ABSTRACT

OBJECTIVE@#To compare the biomechanical stability of three cross-bridge headless compression screws and locking plates in the fixation of Mason type Ⅲ radial head fractures by finite element method.@*METHODS@#Using reverse modeling technology, the radial CT data and internal fixation data of a healthy 25-year-old male were imported into the relevant software. Three-dimensional finite element model of 3 cross-bridge headless compression screws and locking plates for MasonⅢ radial head fractures were established, and the radial head was loaded with 100 N axial loading. The maximum displacement, maximum Von Mises stress and stress distribution of the two groups were compared.@*RESULTS@#The maximum displacements of the three cross-bridge screws group and locking plate group were 0.069 mm and 0.087 mm respectively, and the Von Mises stress peaks were 18.59 MPa and 31.85 MPa respectively. The stress distribution of the three screws group was more uniform.@*CONCLUSION@#Both internal fixation methods can provide good fixation effect. CoMPared with the locking plate fixation method, the 3 cross-bridge headless compression screws fixation is more stable and the stress distribution is more uniform.

ABSTRACT

Introducción: el músculo pronador cuadrado funciona como un estabilizador dinámico de la articulación radiocubital distal. Su reparación posterior a la fijación interna con placa de bloqueo volar en fracturas distales del radio es controvertida. Objetivo: determinar si la reparación del músculo pronador cuadrado influye en los resultados clínicos y funcionales de pacientes con fractura de radio distal que se sometieron a reducción abierta y fijación interna con placa de bloqueo volar. Materiales y métodos: se realizó una revisión sistemática y metanálisis. Las bases de datos analizadas fueron PubMed/Medline, Embase y Bireme/Lilacs (búsqueda realizada hasta el 20 de febrero del año 2023). Los términos de búsqueda fueron: distal radius fracture AND volar plate AND pronator quadratus. Se determinó la calidad metodológica según el manual de revisiones Cochrane. Resultados: en total se incluyeron 4 ensayos clínicos aleatorizados de adecuada calidad metodológica, lo cual corresponde al análisis de 213 participantes. Existen mejores resultados en la puntuación DASH a los 12 meses de seguimiento en el grupo de no reparación del músculo pronador cuadrado DM 2,8 [IC 95%: 0,51;5,10]. No hubo diferencias significativas al año de seguimiento en las puntuaciones de dolor, rangos de movilidad de la muñeca, fuerza de agarre e incidencia de complicaciones. Conclusión: no existe evidencia que sustente la reparación rutinaria del músculo pronador cuadrado posterior a la fijación interna con placa de bloqueo volar en las fracturas de radio distal. (AU)


Introduction: the pronator quadratus muscle functions as a dynamic stabilizer of the distal radioulnar joint, and its repair after internal fixation with volar locking plate in distal radius fractures is controversial. Objective: to determine whether the repair of the pronator quadratus muscle influences the clinical and functional outcomes of patients with distal radius fracture who underwent open reduction and internal fixation with volar locking plate. Materials and methods: a systematic review and meta-analysis were conducted. The analyzed databases were Pubmed/Medline, Embase, and Bireme/Lilacs (search performed until February 20th, 2023). The search terms were distal radius fracture AND volar plate AND pronator quadratus. Methodological quality was determined according to the Cochrane Reviewer's Handbook. Results: a total of 4 randomized clinical trials of adequate methodological quality, corresponding to the analysis of 213 participants, were included. Better DASH scores were observed at 12 months of follow-up in the non-repair group of the pronator quadratus muscle, with a mean difference of 2.8 [95% CI 0.51; 5.10]. There were no significant differences at one-year follow-up in pain scores, wrist mobility ranges, grip strength, and incidence of complications. Conclusion: there is no evidence to support routine repair of the pronator quadratus muscle after internal fixation with volar locking plate in distal radius fractures. (AU)

ABSTRACT

PURPOSE@#The aim of this study was to analyze if any difference exists on the type of immobilisation (above elbow vs. below elbow) in the conservative treatment of distal end radius fractures in adults.@*METHODS@#The study was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses. An electronic literature search was performed up to 1st October 2021 in Medline, Embase, Ovid and Cochrane database using the search terms, "distal end radius fractures OR fracture of distal radius", "conservative treatment OR non-surgical treatment", "above elbow immobilisation" and "below elbow immobilisation". Randomized clinical trials written in English, describing outcome of distal end radius fractures in adults by conservative or non-surgical means using above elbow immobilisation or below elbow immobilisation were included and assessed according to the risk of bias assessment (RoB2) tool by Cochrane collaboration. Non-randomized clinical trials, observational studies, retrospective studies, review articles, commentaries, editorials, conference presentations, operative techniques and articles without availability of full text were excluded from this review. The meta-analysis was performed using Review Manager version 5.4.1 (The Cochrane Collaboration, Copenhagen, Denmark).@*RESULTS@#Six randomized clinical trials were included for quantitative review. High heterogeneity (I2 > 75%) was noted among all the studies. The standard mean difference (MD) between the disability of the arm, shoulder and hand scores in both the groups was 0.52 (95% CI: -0.28 to 1.32) which was statistically non-significant. There was no statistical difference in the radial height (MD = 0.10, 95% CI: -0.91 to 1.12), radial inclination (MD = 0.5, 95% CI: -1.88 to 2.87, palmar tilt (MD =1.06, 95% CI: -0.31 to 2.43) and ulnar variance (MD = 0.05, 95% CI: -0.74 to 0.64). It was observed that shoulder pain occurred more commonly as a complication in above elbow immobilisation and the values were statistically significant (above elbow: 38/92, 41.3%; below elbow: 19/94, 20.2%).@*CONCLUSION@#This two-armed systematic review on the above elbow or below elbow immobilisation to be used for conservative treatment of the distal end radius fracture in adults resulted in non-significant differences in terms of functional and radiological scores among the 2 groups but significant increase in the complication rates in the above elbow group.

ABSTRACT

OBJECTIVE@#To explore the clinical effect of Kirschner wire intramedullary fixation in the treatment of both-bone forearm fractures in children of high altitude area.@*METHODS@#From August 2020 to December 2021, 19 children were treated with Kirschner wire intramedullary fixation including 11 males and 8 females, aged from 4 to 13 years old with an average of (8.16±2.71) years old. The course of disease was 1 to 10 days, with a mean of (4.11±2.51) d. First, close reduction was performed. If the reduction was unsuccessful, limited open reduction was performed, followed by Kirschner wire intramedullary fixation of the radius and ulna. The fracture healing was evaluated by X-ray after operation, and the curative effect was evaluated by Anderson forearm function score standard.@*RESULTS@#The wound healed well after operation, 2 cases had clinical manifestations of needle tail irritation after operation, and the symptoms disappeared after removing the internal fixation. The average follow-up time was(7.68±3.50) months (3 to 14 months). X-ray showed that all fracture healing in follow-up, Anderson forearm function score showed excellent in 16 cases, good in 2 cases and fair in 1 case at the final follow-up.@*CONCLUSION@#Children with fractures in plateau areas often have delayed medical treatment, lack of medical conditions and insufficient compliance. Based on these characteristics, Kirschner wire intramedullary fixation for the treatment of children's double forearm fractures has the advantages of small injury and rapid recovery. It is a kind of operation method that can be popularized.

ABSTRACT

OBJECTIVE@#To analyze the clinical outcomes of mini-plate combined with wireforms in the treatment of Type C distal radial fractures with marginal articular fragments.@*METHODS@#This retrospective study included a total of 10 cases, including 5 males and 5 females, with 6 cases involving the left side and 4 cases involving the right side, of Type C distal radial fractures with marginal articular fragments. The age of the patients ranged from 35 to 67 years old. All patients underwent surgical treatment utilizing mini-plate combined with wireforms for internal fixation.@*RESULTS@#The follow-up period ranged from 6 to 18 months. Complete fracture healing was observed in all cases, with healing times ranging from 10 to 16 weeks. During the entire follow-up period, patients reported high levels of satisfaction with the treatment outcomes, and there were no incidences of incision infection, chronic wrist pain, or wrist traumatic arthritis. At the final follow-up assessment, the Mayo score for the wrist joint ranged from 85 to 95, with 7 cases rated as excellent and 3 cases as good.@*CONCLUSION@#Mini-plate combined with wireforms proves to be an effective fixation method for Type C distal radial fractures with marginal articular fragments. The early initiation of wrist joint exercises, strong fixation, maintenance of proper reduction, minimal complications, and high rates of excellent and good outcomes demonstrate the reliability and efficacy of this treatment approach.

ABSTRACT

OBJECTIVE@#The relationship between the distal screws and the wrist articular surface was assessed by the additional lateral oblique fluoroscopic view during the operation, and the dorsal tangential view of the wrist was used to observe whether the distal screw penetrated the dorsal cortex, so as to evaluate the clinical efficacy of the volar locking plate in the treatment of distal radius fractures.@*METHODS@#From January 2020 to June 2021, 45 cases of fresh distal radius fractures were treated using the volar Henry's approach, including 20 males and 25 females, aged from 32 to 75 years old with an average of (52.4±8.1) years old. During the operation, they were divided into 2 groups according to the different intraoperative fluoroscopic views:the control group of 20 cases, treated with standard anteroposterior and lateral fluoroscopic view;25 cases in the observation group, additional lateral oblique fluoroscopic view and dorsal tangential view of the wrist were taken. The wrist joint function score and postoperative complications were evaluated at 6 weeks, 3 and 6 months after operation between two groups.@*RESULTS@#All 45 patients were followed up and the duration ranged from 6 to 14 months, with an average of (10.8±1.7) months, all patients achieved bone union and the incision healed well. The incidence of postoperative complications in the observation group was lower than that in the control group, and the difference was statistically significant (P<0.05). In terms of Gartland-Werley score of wrist joint function, the score of wrist function in the observation group was (4.58±1.31) at 6 weeks, (2.98±0.63) at 3 months and (1.95±0.65) at 6 months post-operatively, which were better than those in the control group (6.32±1.96) at 6 weeks, (3.63±0.76) at 3 months and (2.43±0.73) at 6 months. The difference was statistically significant (P<0.05). In the observation group, 7/25 cases(28%) were found to have screw penetration during the operation by additional lateral oblique and dorsal tangential radiograph fluoroscopic views of wrist.@*CONCLUSION@#The addition of lateral oblique and dorsal tangential during the operation could improve the accuracy of distal screw placement, reduce postoperative complications, and achieve early functional exercise.

ABSTRACT

OBJECTIVE@#To investigate the effectiveness of distal radius core decompression in the treatment of chronic wrist pain caused by various etiologies.@*METHODS@#A retrospective analysis was performed for the clinical data of 10 patients with chronic wrist pain treated with distal radial core decompression between January 2018 and December 2021. There were 6 males and 4 females with an average age of 37.4 years (range, 21-55 years). The disease duration ranged from 7 to 72 months, with an average of 26.5 months. Preoperative MRI examination showed that 10 cases had bone marrow edema at the distal radius on the affected side, and 8 cases had bone marrow edema in the carpal bones such as scaphoid and lunate bone. Among them, 3 patients had a history of wrist fracture, and 2 patients had Kienböck diseases (1 case each in stage ⅡB and stage ⅢA). Three cases were combined with triangular fibrocartilage complex (TFCC) type 1A injury. Two cases were combined with osteoarthritis, 1 of them was complicated with severe traumatic arthritis, the wrist arthroscopy showed that the TFCC was completely lost and could not be repaired, and the cartilage of the lunate bone and the ulnar head were severely worn.Visual analogue scale (VAS) score was used to evaluate the relief of wrist pain before operation, at 6 months after operation, and at last follow-up, and the range of motion of the affected wrist in dorsiflexion, palmar flexion, ulnar deviation, and radial deviation was measured. The degree of bone marrow edema was evaluated according to T1WI, T2WI, and STIR sequences of MRI.@*RESULTS@#All the patients were followed up 12-22 months, with an average of 16.4 months. Except for 1 patient who experienced persistent wrist joint pain and limited mobility after operation, the remaining 9 patients showed significant improvement in pain symptoms and wrist joint mobility. The VAS score and range of motion of wrist dorsiflexion, palmar flexion, ulnar deviation, and radial deviation at 6 months after operation and at last follow-up were significantly improved when compared with those before operation, the VAS score and the range of motion of wrist ulnar deviation and radial deviation at last follow-up were further improved when compared with those at 6 months after operation, all showing significant differences ( P<0.05). There was no significant difference in wrist dorsiflexion and palmar flexion between at 6 months after operation and at last follow-up ( P>0.05). Bone marrow edema was improved in 6 patients on MRI at 6 months after operation, and was also improved in other patients at last follow-up.@*CONCLUSION@#For chronic wrist pain caused by a variety of causes, distal radius core decompression can directly reduce the pressure of the medullary cavity of the distal radius, improve the blood supply of the corresponding distal structure, significantly alleviate chronic wrist pain, and provide an option for clinical treatment.

ABSTRACT

OBJECTIVE@#To investigate the effectiveness of sequential plate internal fixation in the correction of Madelung deformity after ulnar osteotomy and shortening.@*METHODS@#The clinical data of 13 patients with Madelung deformity admitted between September 2015 and July 2021 were retrospectively analyzed. There were 5 males and 8 females with an average age of 18.3 years ranging from 17 to 23 years. The disease duration ranged from 12 to 24 months, with an average of 17 months. Three cases had a clear history of trauma. All patients had external radial deviation deformity and limited movement of the ulnar deviation, and the ulnar impact pain was significant during ulnar deviation movement; 9 patients had limited wrist joint supination movement, and the supination movement was normal. In the first stage, ulnar osteotomy and shortening combined with external fixator were used to correct wrist deformity in 13 patients. After operation, bone transfer was performed 6 times per day, with adjustments made every 4 hours, which was 1 mm per day. After the osteotomy was in place, the ulnar plate internal fixation was performed to reconstruct the ulnar stability in the second stage. The Cooney wrist joint score was used to assess the pain, function, range of motion, flexion and extension range of motion, and grip strength of the wrist joint before operation and before the removal of internal fixator. The subjective feeling and appearance satisfaction of patients were recorded.@*RESULTS@#After the second-stage operation, all the 13 patients were followed up 10-22 months, with an average of 15 months. The deformity of wrist joint disappeared after operation, and the flexion, extension, and ulnar deviation were basically normal. There was no complication such as ulnar impingement sign, nonunion or infection. Wrist function, pain, and range of motion were significantly improved after operation, except for 1 patient who had no significant improvement in rotation and pain. The ulnar internal fixator was removed at 10-18 months after the second-stage operation. The scores of pain, function, range of motion, flexion and extension range of motion, and grip strength in the Cooney wrist score before removal of internal fixator significantly improved when compared with those before operation ( P<0.05). Subjective and appearance satisfaction of patients were excellent in 9 cases, good in 3 cases, and fair in 1 case.@*CONCLUSION@#Ulnar osteotomy and shortening with sequential plate internal fixation for correction of Madelung deformity, with mild postoperative pain, can effectively avoid bone nonunion, improve wrist joint function, and have significant effectiveness.

ABSTRACT

Abstract Objective Over the last decades, volar locking plates (VLPs) have been the mainstay treatment for distal radius fractures (DRFs). With the growing body of evidence, we systematically reviewed studies on recent VLP modifications. Methods A systematic search was performed in the PubMed/MEDLINE database for studies published in English in the past five years. The inclusion criteria were randomized controlled trials (RCTs) on the operative treatment of DRFs. We excluded ongoing trials and studies not directly addressing DRF. The primary outcomes assessed were subjective (such as the scores on the Disabilities of the Arm, Shoulder and Hand [DASH] questionnaire, the Patient-rated Wrist Evaluation [PRWE], the European Quality of Life-5 Dimensions [EQ-5D], the 36-item Short Form Health Survey [SF-36], and the Visual Analog Scale [VAS]) and objective clinical outcomes (the complication rate). Results We identified 29 articles published from 2016 to 2020 with high quality of evidence, except for one, which had evidence of moderate quality. In total, 3,079 DRFs were analyzed in the present study. All studies except one had a greater proportion of female participants, and only in 1 study the mean age of the sample was < 40 years old. There were no significant differences between the VLP and external fixation (EF) in terms of the scores on the DASH (p= 0.18) and PRWE (p= 0.77). The VLP alone without pronator quadratus (PQ) repair yielded significantly better outcomes. Conclusion In unstable fractures, the VLP and EF yielded comparable long-term results. There is no clear benefit of adding PQ repair to current the VLP surgical technique. Level of EvidenceLevel I


Resumo Objetivo Nas últimas décadas, a placa volar bloqueada (PVB) tem sido o tratamento principal para fraturas do rádio distal (FRDs). Com o crescente conjunto de evidências, revisamos sistematicamente estudos sobre modificações recentes na PVB. Métodos Uma pesquisa sistemática foi realizada utilizando o banco de dados PubMed/MEDLINE por estudos publicados em inglês nos últimos cinco anos. Os critérios de inclusão foram ensaios clínicos controlados e randomizados (ECCRs) sobre o tratamento cirúrgico de FRDs. Excluímos ensaios e estudos em andamento que não abordavam diretamente a FRD. Os desfechos primários avaliados foram desfechos clínicos subjetivos (como as pontuações no questionário de Deficiências do Braço, Ombro e Mão [Disabilities of the Arm, Shoulder and Hand, DASH, em inglês], na Avaliação do Punho Classificada pelo Paciente [Patient-rated Wrist Evaluation, PRWE, em inglês], no questionário Qualidade de Vida Europeia - 5 Dimensões [European Quality of Life-5 Dimensions, EQ-5D, em inglês], na Pesquisa de Saúde por Formulário Curto de 36 Itens [36-item Short Form Health Survey, SF-36, em inglês], e na Escala Visual Analógica [EVA]) e objetivos (taxa de complicações). Resultados Identificamos 29 artigos publicados entre 2016 e 2020 com alta qualidade de evidência, exceto por um, de qualidade moderada. Ao todo, foram analisadas 3.079 FRDs neste estudo, Todos os estudos analisados, exceto por um, tinham maior proporção de participantes do gênero feminino, e somente em 1 estudo a idade média da amostra foi < 40 anos. Não houve diferença significativa entre a PVB e fixação externa (FE) em termos das pontuações no DASH (p= 0,18) e na PRWE (p= 0,77). Os resultados da PVB isolada, sem qualquer reparo do pronador quadrado (PQ), foram significativamente melhores. Conclusão Em fraturas instáveis, a PVB e a FE produziram resultados comparáveis no longo prazo. Não há um benefício claro em se adicionar reparo do PQ à técnica cirúrgica atual da PVB.

ABSTRACT

Objetivo: Comparar los resultados y las complicaciones entre la fijación percutánea con clavijas (FPC) y el enclavado endomedular elástico (EEE). materiales y métodos:Se evaluaron las radiografías para determinar deformidades angulares en la consolidación. Se usó el sistema de Clavien-Dindo adaptado para clasificar las complicaciones. Resultados: El grupo A (FPC) incluyó a 17 pacientes y el grupo B (EEE), a 19. La edad promedio era de 12.5 ± 1.6 años y el seguimiento promedio fue de 27.6 ± 16.6 meses. Los pacientes con EEE requirieron menos tiempo de inmovilización (2.8 ± 1.8 vs. 5.9 ± 1.3 semanas, p 0,00029). Un paciente de cada grupo tuvo una angulación >10° en la consolidación. La tasa de complicaciones fue mayor en el grupo A (18% vs. 5,3%, p 0,27). En el grupo A, hubo 2 complicaciones tipo III (pérdida de corrección) y 2 tipo II (infección y granuloma). Un paciente del grupo B presentó una complicación tipo I (prominencia del implante). Dieciséis pacientes del grupo B se sometieron a una segunda cirugía para extraer el implante. Dos del grupo A requirieron revisión de la fijación por pérdida de alineación. Conclusiones: Ambas técnicas son eficaces para estabilizar fracturas metafiso-diafisarias de radio distal en adolescentes. El EEE tiene la ventaja de una inmovilización más corta y menos complicaciones, pero es más caro y requiere otra cirugía para extraer el implante. La FPC no requiere de anestesia para extraer el implante, aunque sí una inmovilización más prolongada y la tasa de complicaciones es más alta. Nivel de Evidencia: III


Objective: To compare results and complications of closed reduction percutaneous pinning (CRPP) versus dorsal entry elastic intramedullary nails (ESIN). Materials and methods: Radiographs were evaluated to determine angular deformities at the time of radiographic union. Complications were graded with a modification of the Clavien-Dindo classification. Results: The CRPP group consisted of 17 patients (Group A) whereas the ESIN group consisted of 19 patients (Group B). The average age of the patient cohort was 12.5±1.6 years. The average follow-up was 27.6±16.6 months. The demographic data revealed no differences between groups (p> 0.05). Patients treated with ESIN required a shorter immobilization time (2.8±1.8 versus 5.9±1.3 weeks, p 0.00029). One patient in each group presented an angulation >10° at the time of consolidation. The complication rate was higher in group A (18% versus 5.3%, p 0.27). According to the Clavien-Dindo classification, group A presented 2 type II (infection and granuloma), and 2 type III complications (loss of reduction). Group B presented one type I complication (implant prominence). Sixteen patients in group B underwent a second procedure for hardware removal. Two patients (11.8%) in group A required revision due to loss of reduction. Conclusions: Both techniques are effective in stabilizing metaphyseal-diaphyseal fractures of the distal radius in the adolescent population. ESIN has the advantage of requiring a shorter immobilization time and fewer complications but needs a second surgery for implant removal. CRPP does not require anesthesia for implant removal, although it requires a longer postoperative immobilization, and has a higher complication rate. Level of Evidence: III

ABSTRACT

OBJECTIVE@#To investigate the effect of suture of pronator muscle on forearm function after modified Henry approach for distal radius fractures.@*METHODS@#from January 2018 to December 2020, 220 patients with distal radius fractures were treated with open reduction and locking plate internal fixation through the modified Henry approach. They were divided into two groups according to different suture methods. There were 112 cases in the intraoperative suture group, including 35 males and 77 females;The age ranged from 37 to 65(48.5±7.4) years;AO classification of fracture, 46 cases of type B and 66 cases of type C;After fracture reduction and locking plate fixation, the pronator muscle was opened and sutured. There were 108 cases in the non suture group, 32 males and 76 females;The age ranged from 34 to 67(47.6±7.8) years;There were 41 cases of fracture type B and 67 cases of fracture type C;After fracture reduction and locking plate fixation, the open pronator muscle was not sutured, and it was laid on the surface of the plate in situ. The range of wrist motion (pronation, supination, palmar inclination and dorsiflexion), the score of disability of arm shoulder and hand dash and visual analog scale(VAS) were compared between the two groups at 6 weeks and 6 months after operation.@*RESULTS@#All 220 patients were followed up for 6 to 18 (8.5±1.3) months. There was no significant difference in the range of motion and DASH score of forearm and wrist between the two groups 6 weeks after operation (P>0.05);There was significant difference in VAS score between suture group (2.6±1.2) and non suture group (5.8±2.3)(P<0.05). Six months after operation, there was no significant difference in the range of motion, DASH score and VAS score of forearm and wrist between the two groups(P>0.05).@*CONCLUSION@#The modified Henry approach has no obvious advantages in the range of wrist movement and upper limb function, but the intraoperative suture of pronator can reduce the early postoperative pain. It is suggested that the pronator should be sutured during the operation.

ABSTRACT

Introducción: Las fracturas metafisarias de radio distal son las fracturas más frecuentes en la edad pediátrica, siendo 30% del total de las mismas. Mantener la reducción de las fracturas desplazadas no siempre es posible: el re-desplazamiento es la principal complicación de estas lesiones. Clásicamente se realizó tratamiento con maniobra y yeso, aunque en los últimos años se asoció fijación con Kirschner wire (Kw) en búsqueda de disminuir el re-desplazamiento. El objetivo de nuestro trabajo es identificar factores de riesgo en búsqueda de realizar el mejor tratamiento siendo lo menos agresivo posible. Materiales y métodos: Se realizó una búsqueda sistematizada a través del buscador electrónico PubMed. La misma alcanzó un total de 4594 artículos, que de acuerdo con los criterios de inclusión y exclusión se seleccionaron 15 trabajos para realizar nuestra revisión bibliográfica. Resultados: Se destaca que la mayoría de los artículos encontrados son de nivel de evidencia III y IV. Nuestra búsqueda refleja un índice de re-desplazamiento entre 20-39% mediante yeso a las 2 semanas; asi como un índice de re-manipulación entre el 5-10 % del total de las fracturas desplazadas. La mayoría de los estudios analizados intentan identificar los factores de riesgo más importantes para el re-desplazamiento de las fracturas, de lo que se destacan el grado de desplazamiento inicial de la fractura y la reducción lograda de la misma. A su vez, otros artículos valoran los resultados del tratamiento mediante estabilización con yeso o fijación mediante Kirschner wire. Conclusión: el desplazamiento inicial de la fractura y la reducción lograda en block quirúrgico (BQ) son los factores de riesgo más importantes para el re-desplazamiento. Si bien la técnica de enyesado no es considerado una variable estadísticamente significativa, es considerada una variable importante en cuanto al pronóstico de la lesión, destacando al moldeado de 3 puntos como principal índice a considerar. Se considera aconsejable asociar un Kw en aquellas fracturas cabalgadas en las que no se logra una reducción anatómica en block quirúrgico.


Introduction: Distal radius metaphyseal fractures are the most frequent fractures in pediatric age, accounting for 30% of the total. Maintaining the reduction of displaced fractures is not always possible: re-displacement is the main complication of these injuries. Classically, treatment was performed with a maneuver and a cast, although in recent years fixation with Kirschner wire (Kw) has been associated in search of reducing re-displacement. The objective of our work is to identify risk factors in search of the best treatment while being the least aggressive possible. Materials and methods: A systematic search was carried out using the PubMed electronic search engine. It reached a total of 4594 articles, which according to the inclusion and exclusion criteria, 15 papers were selected for our bibliographic review. Results: It should be noted that most of the articles found are level of evidence III and IV. Our search reflects a re-displacement rate between 20-39% using a cast at 2 weeks; as well as a re-manipulation index between 5-10% of all displaced fractures. Most of the studies analyzed attempt to identify the most important risk factors for the re-displacement of fractures, of which the degree of initial displacement of the fracture and the reduction achieved are highlighted. In turn, other articles assess the results of treatment by stabilization with plaster or fixation with Kirschner wire. Conclusion: the initial displacement of the fracture and the reduction achieved in the surgical block (BQ) are the most important risk factors for re-displacement. Although the casting technique is not considered a statistically significant variable, it is considered an important variable in terms of the prognosis of the injury, highlighting the 3-point casting as the main index to be considered. It is considered advisable to associate a Kw in those mounted fractures in which an anatomical reduction in surgical block is not achieved.


Introdução: As fraturas metafisárias do rádio distal são as mais frequentes na idade pediátrica, correspondendo a 30% do total. Manter a redução das fraturas desviadas nem sempre é possível: o deslocamento é a principal complicação dessas lesões. Classicamente, o tratamento era realizado com manobra e gesso, embora nos últimos anos a fixação com fio de Kirschner (Kw) tenha sido associada na busca pela redução do deslocamento. O objetivo do nosso trabalho é identificar os fatores de risco em busca do melhor tratamento sendo o menos agressivo possível. Materiais e métodos: uma busca sistemática foi realizada usando o mecanismo de busca eletrônico PubMed. Chegou-se a um total de 4.594 artigos, que de acordo com os critérios de inclusão e exclusão, foram selecionados 15 artigos para nossa revisão bibliográfica. Resultados: Ressalta-se que a maioria dos artigos encontrados são de nível de evidência III e IV. Nossa pesquisa reflete uma taxa de re-deslocamento entre 20-39% usando um gesso em 2 semanas; bem como um índice de remanipulação entre 5-10% de todas as fraturas deslocadas. A maioria dos estudos analisados ​​busca identificar os fatores de risco mais importantes para o deslocamento das fraturas, que incluem o grau de deslocamento inicial da fratura e a redução alcançada. Por sua vez, outros artigos avaliam os resultados do tratamento com estabilização gessada ou fixação com fio de Kirschner. Conclusão: o deslocamento inicial da fratura e a redução alcançada no bloqueio cirúrgico (QB) são os fatores de risco mais importantes para o deslocamento. Embora a técnica de gesso não seja considerada uma variável estatisticamente significativa, é considerada uma variável importante em termos de prognóstico da lesão, destacando-se o gesso em 3 pontos como o principal índice a ser considerado. Considera-se aconselhável associar um Kw nas fraturas montadas em que não se consegue redução anatômica no bloqueio cirúrgico.

ABSTRACT

OBJECTIVE@#To compare therapeutic effects of internal fixation with volar locking plate in treating extension and flexion type of distal radius fracture (DRF).@*METHODS@#From January 2015 to June 2018, 103 patients with DRF were retrospectively analyzed. According to original fracture displacement direction, patients were divided into extension fracture(Colles) group and flexion fracture (Smith) group. In Colles fracture group, there were 24 males and 44 females aged from 20 to 79 years old with an average of (59.0±13.4) years old;according to AO classification, 9 patients of type A2, 13 patients of type A3, 16 patientsof type C1, 17 patients of type C2 and 13 patients of type C3;the time from injury to operation ranged from 2 to 9 days with an average of (3.9±0.8) days. In Smith fracture group, there were 15 males and 20 females, aged from 27 to 87 years old with an average of (60.1±15.3) years old;according to AO classification, 4 patienst of A2, 7 patients of A3, 14 patients of C1, 5 patients of C2 and 5 patients of C3;the time from injury to operation ranged from 2 to 6 days with an average of (4.1±0.9) days. Operation time, fracture healing time and postoperative complications were recorded between two groups. Disabilities of arm, shoulder and hand (DASH) score at 6 and 8 weeks, 6 and 8 months were used to evaluate functional recovery of affected limbs during each follow up. Volar tilt, radial inclination and radius height were measured at 8 months after operation. Mayo score was measured at 8 months after operation to evaluate recovery of limb function.@*RESULTS@#All patients were followed up for 8 to 30 months with an average of (14.8±4.3) months, and no difference in follow up between two groups (@*CONCLUSION@#Patients with Colles fracture and Smith fracture could receive good reduction and fixation through volar locking plate. The radiographic parameters of both groups recovered satisfactorily after operation. Recovery of volar tilt of Smith fracture group is better than that of Colles fracture group, and early recovery function of Colles fracture group is better than that of Smith group, but there is no significant difference in long-term wrist joint function and incidence of postoperative complications between two groups.

ABSTRACT

Resumen: Introducción: Las fracturas intraarticulares de radio distal son un desafío terapéutico para el cirujano ortopedista. Hay estudios que avalan el uso de la fluoroscopía y otros promueven la artroscopia. Con este trabajo intentamos resumir la evidencia, para determinar si la asistencia artroscópica aporta beneficios adicionales para evitar incongruencias articulares en comparación con los resultados obtenidos bajo asistencia fluoroscópica. Material y métodos: Búsqueda sistemática de estudios prospectivos, retrospectivos, de cohortes, seguimiento, ensayos clínicos en PubMed, MEDLINE, Scopus, Scielo, Embase, Google Scholar y otras fuentes nacionales, incluyendo como palabras clave los términos: intraarticular distal radius fracture, wrist arthroscopy, arthroscopy, fluoroscopy. Los valores medios y desvíos estándar para cada característica, obtenidos de los trabajos seleccionados fueron analizados usando estadística descriptiva y gráficos ilustrativos. Resultados: Fueron evaluados 463 pacientes (256 mujeres y 207 hombres), con una edad promedio de 48.29 años y rango de 39 a 64 años. Los dos tratamientos (A y F) fueron homogéneos en cuanto a la edad de los pacientes que reportan (p = 0.5820) y el tiempo de seguimiento promedio (p = 0.9597). Sólo la desviación cubital y el DASH, para las cuales el grupo de artroscopía tuvo mejor desempeño, en las variables restantes las diferencias no fueron significativas. Conclusión: La evidencia disponible hasta la fecha es controvertida y no permite hacer recomendaciones a favor o en contra de estas intervenciones, encontrando otros factores que podrían influir en la toma de decisiones.


Abstract: Introduction: Intraarticular distal radius fractures are a therapeutic challenge for the orthopedist surgeon there are studies that support the use of fluoroscopy, and others promote arthroscopy, with this work we try to summarize the evidence, to determine whether arthroscopic assistance provides additional benefits to avoid joint incongruities compared to results obtained under fluoroscopic assistance. Material and methods: Systematic search for prospective, retrospective, cohort, follow-up, clinical trials on PubMed, MEDLINE, Scopus, Scielo, Embase, Google Scholar and other national sources, including as keywords the terms: «intra-articular distal radius fracture¼, «wrist arthroscopy¼, «arthroscopy¼, «fluoroscopy¼. The average values and standard offsets for each characteristic, obtained from the selected works, were analyzed using descriptive statistics and illustrative graphs. Results: 463 patients (256 women and 207 men) were evaluated, with an average age of 48.29 years and range from 39 to 64 years. The two treatments (A and F) were homogeneous in terms of the age of the patients reporting (p = 0.5820) and the average follow-up time (p = 0.9597). Only the ulnar deviation and DASH score, for which the arthroscopy group performed best, in the remaining variables the differences were not significant. Conclusion: The evidence available to date is conflicting, and does not allow recommendations to be made for or against these interventions, finding other factors that could influence decision-making.

ABSTRACT

RESUMEN Introducción: Las pseudoartrosis diafisarias de cúbito y radio constituyen un desafío terapéutico para el cirujano ortopédico, a causa de la dificultad para lograr y mantener la reducción de dos huesos paralelos en presencia de músculos pronadores y supinadores que ejercen influencias angulares y rotacionales. Objetivo: Evaluar la eficacia de la aplicación del minifijador externo combinado con el injerto óseo homólogo en esta afección. Métodos: Se realizó un estudio longitudinal, retrospectivo de corte transversal en 74 pacientes operados de pseudoartrosis diafisaria de cúbito y radio desde enero de 2000 hasta diciembre de 2014, en el Complejo Científico Ortopédico Internacional Frank País, en los que se utilizó el modelo de minifijación externa RALCA® e injerto óseo homólogo del Banco de Tejidos ORTOP. Resultados: La pseudoartrosis fue más frecuente en hombres (73 por ciento) y en las edades comprendidas entre 30 y 39 años. La localización más frecuente fue en el cúbito, en su tercio superior (52 por ciento). La mayoría de los pacientes presentaron una pseudoartrosis no viable (56 por ciento). Se consolidó en 66 por ciento de los pacientes antes de las 18 semanas y en solo uno no se obtuvo la consolidación. El hueso que menos tiempo requirió para consolidar fue el radio. En la evaluación de la eficacia de la técnica quirúrgica se obtuvo 62 por ciento de resultados buenos, 33 por ciento regulares y 5 por ciento malos. Conclusiones: La asociación de la minifijación externa modelo RALCA® e injerto óseo homólogo de banco mostró buenos resultados en el tratamiento de la pseudoartrosis de cúbito y radio(AU)


ABSTRACT Introduction: Diaphyseal pseudoarthroses of the ulna and radius constitute a therapeutic challenge for the orthopedic surgeon, due to the difficulty to achieve and maintain the reduction of two parallel bones in the presence of pronator and supinator muscles that exert angular and rotational influences. Objective: To evaluate the effectiveness of using external minifixator combined with homologous bone graft in the treatment of this condition. Method: A longitudinal, retrospective and cross-sectional study was carried out with 74 patients operated on, from January 2000 to December 2014, for diaphyseal pseudoarthrosis of the ulna or radius at Frank País International Orthopedic Scientific Complex, cases in which RALCA® external minifixation and homologous bone graft from the ORTOP Tissue Bank were used. Results: Pseudoarthrosis was more frequent in men (73 percent) and at ages 30-39 years. The most frequent location was the ulna, in its upper third (52 percent). Most of the patients had nonviable pseudoarthrosis (56 percent). The condition was consolidated in 66 percent of the patients within 18 weeks, and only one did not achieve consolidation. The bone that took the least time to heal was the radius. In the evaluation of the effectiveness of the surgical technique, 62% obtained good outcomes; 33 percent fair outcomes; and 5 percent, poor outcomes. Conclusions: The association of the RALCA® model miniexternal fixation and homologous bone graft from the Bank showed good outcomes in the treatment of ulna and radius pseudoarthrosis(AU)

ABSTRACT

Abstract Objective The present paper aims to present results from radiographic evaluations of patients with extra-articular distal radius fractures submitted to percutaneous fixation with a 3.5 mm solid screw. Methods Analytical, descriptive and retrospective case series of 16 patients with evaluation of the radiographic parameters. Results The average age of the study population was 46.5 years old (25-60 years old); 81.25% of the sample was female. The average time until surgery was 8.8 days (4-14 days). The mean preprocedural volar tilt was - 7.41° (−23.48°-5.29°, standard deviation [SD] ± 6.59°). The mean volar tilt immediately after surgery was 5.93° (SD ± 6.23°, p< 0.001). There was no statistical difference in volar tilt values after 6 months of follow-up. The mean preprocedural radial height was 4.13 mm (−7.8 mm-9.5 mm, SD ± 5.06 mm). There was a statistically significant increase at the immediate postoperative period to 10.04 mm (p= 0.002), and a significant reduction at 6 months to 9.55 mm (p= 0.012). The consolidation rate was 100% with the technique used, with a minimal complication rate. No patient had infection or required a reoperation. Conclusion The technique was effective for the treatment of distal radial extra-articular fractures at 6 months, with a low complication rate; radiographic parameters values were acceptable and close to the anatomical ones.


Resumo Objetivo Apresentar o resultado das avaliações radiográficas dos pacientes com fraturas extra-articulares do rádio distal submetidos a fixação percutânea com parafuso maciço de 3.5mm. Métodos Série de casos, analítica, descritiva e retrospectiva de 16 pacientes com avaliação dos parâmetros radiográficos da técnica utilizada. Resultados A média de idade da população estudada foi de 46,5 anos (25-60 anos), sendo 81,25% do sexo feminino. O tempo de espera até a cirurgia foi de 8,8 dias (4-14 dias). O tilt volar médio pré-procedimento foi - 7,41° (−23,48°-5,29°, desvio padrão [DP] ± 6,59°). O tilt volar imediatamente após o procedimento cirúrgico foi de 5,93° (DP ± 6,23°, p< 0,001). Sem diferença estatística nos valores de tilt volar ao final de 6 meses de evolução. A altura radial pré-procedimento foi de 4,13 mm (−7,8°-9,5°, DP ± 5,06°). Aumento estatisticamente significativo no pós-operatório imediato para 10,04 mm (p= 0,002). Redução significativa ao final de 6 meses para 9,55 mm (p= 0,012). Atingimos 100% de consolidação com a técnica utilizada, com índice mínimo de complicações. Nenhum paciente apresentou infecção ou precisou ser reoperado. Conclusão A técnica mostrou-se eficaz para o tratamento de fraturas extra-articulares da extremidade distal do rádio ao final de 6 meses, com baixo índice de complicações e parâmetros radiográficos aceitáveis e próximos dos valores anatômicos.

ABSTRACT

Introducción: El tratamiento de las fracturas de muñeca con placas volares bloqueadas puede ser insuficiente para las fracturas con fragmentos volares marginales distales a la línea de inserción distal del pronador cuadrado, sitio de inserción de importantes ligamentos. Objetivo: Evaluar la reproducibilidad de la técnica y los resultados del tratamiento de fracturas marginales volares de radio distal con clavijas, capturando el fragmento volar y dejándolas debajo de la placa volar bloqueada de radio distal. Materiales y Métodos: La técnica quirúrgica utiliza una o varias clavijas para fijar el fragmento volar semilunar del radio distal, bloqueándolas debajo de la placa. Inicialmente efectuamos una simulación cadavérica. Luego, realizamos un estudio retrospectivo que incluyó a 7 pacientes con fracturas de radio distal intrarticular con un fragmento marginal volar distal a la línea de la orilla, tratados entre septiembre de 2014 y febrero de 2015. El promedio de edad era de 53 años, y el del seguimiento, de 16 meses. Se obtuvieron radiografías en sucesivos controles. Al alta se evaluaron el rango de movilidad, la fuerza de prensión y dos puntajes funcionales. Resultados: Todas las fracturas consolidaron satisfactoriamente manteniendo la reducción del fragmento marginal volar. No hubo casos con inestabilidad radiocubital inferior como secuela. Conclusión: La fijación adicional del fragmento marginal volar lunar del radio con clavijas dobladas por debajo de la placa ofrece una alternativa de estabilización sencilla, económica y adecuada para suplir la fijación de un fragmento que la placa sola no estabilizaría adecuadamente. Nivel de Evidencia: IV


Introduction: Wrist fracture management with volar locking plates may be insufficient in fractures with volar marginal fragments distal to the line insertion of the pronator quadratus, the insertion site of important ligaments. Objective: To evaluate the reproducibility and results for the treatment of volar marginal fragment in distal radius fractures with a technique of pin fixation, capturing the fragment and securing them under the distal radius volar locking plate. Materials and Methods: The surgical technique uses one or more pins for the fixation of the volar lunate facet fragment in the distal radius, securing the pins under the locking plate. We initially performed a cadaveric simulation. Then we conducted a retrospective study on 7 patients with distal radius intra-articular fractures and volar marginal fragments distal to the watershed line, treated between September 2014 and February 2015. The average age was 53 years, and the average follow-up was 16 months. Radiographs were obtained in successive controls. Range of motion, grip strength, and 2 functional scores were assessed at discharge. Results: All fractures healed successfully maintaining reduction of the volar marginal fragment. There were no cases of postoperative distal radio ulnar joint instability. Conclusion: Additional fixation of volar marginal fragment in distal radius fractures with bent pins under the plate provides an easy, affordable and adequate alternative to supply the adequate fragment stabilization that plate-alone techniques do not achieve. Level of Evidence: IV
