RESUMO
Objective To classify traumatic triangular fibrocartilage complex(TFCC)injury based on 3.0T MR.Methods A total of 46 patients with definite history of wrist trauma admitted were collected.All patients underwent MRI scanning within 3 days after trauma,and the MRI findings were classified as follows according to the Palmer classification criteria:the focal structures of triangular fibro-cartilage(articular disc)(TFC)injury,the horizontal of the articular disc tear,injuries of ulnar styloid attachment and ulnar fovea attach-ment in TFC,ulnolunate and ulnotriquetral ligaments injuries,injury of the radial sigmoid notch junction,meniscal homologous inju-ry.The presence of TFCC injury was eventually confirmed by surgery in all patients.Results Of 46 patients,38 patients could be classified by Palmer,and there were 10 cases with type ⅠA,23 cases with type ⅠB,3 cases with type ⅠC and 2 cases with type ⅠD.A total of 8 patients were not suitable for Palmer type,and there were 3 patients with horizontal tears in the articular disc and 5 patients with meniscus homologous injuries.Conclusion The 3.0T MR can not only show various subtypes of Palmer classification,but also refine and supplement the classification based on the original classification,such as the injuries of ulnar styloid attachment and ulnar fovea attachment at the ulnar end of the articular disc,horizontal tear of the articular disc,meniscus homologous injury,etc.
RESUMO
BACKGROUND:At present,wrist protection products designed in and outside China have not solved the contradiction between protecting the wrist joint from injury and maintaining the flexible movement of the wrist joint. OBJECTIVE:To investigate the biomechanical mechanism of dorsiflexion injury of the wrist joint in elderly people after falls,and to provide a biomechanical basis for the prevention and treatment of wrist injury in elderly people after falls. METHODS:A 65-year-old man was selected to obtain the original data by uninterrupted CT scan of the middle and lower 2/3 of his left forearm up to the end of the finger.A finite element model of wrist dorsiflexion was established using ANSYS 12.0 finite element software.The palm surface of the model was constrained,and the model at a velocity load of 2 m/s in the direction of vertical downward was given to simulate the injury state of the palm when the elderly fall.The stress distribution of the soft tissues and bones of the wrist joint and the change of the stress with time were observed after the load was applied. RESULTS AND CONCLUSION:(1)A realistic and effective finite element model of the dorsal extension position of the wrist joint of the elderly was established.The soft tissue stresses were mainly concentrated in the small fissure of the palm and the dorsal side of the wrist after loading.The skeletal stresses were mainly concentrated in the lower end of the ulnar radius dorsally.The stresses in the lower end of the radius were the greatest.The palmar stresses were mainly concentrated in the middle and lower 1/3 of the radius and the hook bone.The stress distribution of the ulnar radius was asymmetric,and the stresses in the radius were more concentrated.(2)The results of the study are consistent with the clinical situation of a fallen wrist injury in elderly people,and can be used to explain the mechanism of wrist dorsiflexion injury,which can provide the biomechanical basis for the design of wrist protection devices that can be used to prevent wrist injury induced by falling and the treatment of wrist injury in elderly people.
RESUMO
BACKGROUND:Scaphoid fractures are common wrist fractures.The percutaneous screw is used to treat scaphoid fractures.The closed reduction of the fracture site,the precise placement of the hollow compression screw in the scaphoid axis and the compression fixation of the fracture site can promote fracture healing and achieve the better function of the wrist. OBJECTIVE:To evaluate the efficacy of percutaneous hollow compression screw fixation of scaphoid fractures using a novel Kirschner wire guide. METHODS:Between January 2015 and December 2020,clinical data from 15 patients with scaphoid fractures selected at the Department of Hand Surgery,Third Hospital of Hebei Medical University were retrospectively analyzed.All patients underwent percutaneous hollow compression screw fixation by a novel Kirschner wire guide.Fracture healing time,operation time,number of intraoperative fluoroscopies,time to return to work and complications were collected.According to the modified Mayo wrist scoring system,the functional outcomes of wrists were assessed 12 months after surgery.Wrist flexion,extension,ulnar deviation,radial deviation and grip strength were measured. RESULTS AND CONCLUSION:All patients were followed up for 12 months.The compression screw was located in the axial position of the scaphoid by routine immediate postoperative radiographs.All scaphoid fractures united at an average of 10.0 weeks.The average operation time was 55.7 minutes.The number of intraoperative fluoroscopies was 10.9.The average time to return to work was 10.3 weeks.The results of wrist joint function were excellent in 9 cases,good in 5 cases,and average in 1 case,with an excellent and good rate of 93.3%.No significant differences in wrist flexion,extension,ulnar deviation,radial deviation and grip strength were found between the affected and healthy sides(P>0.05).None of the patients had wound infection,malunion,screw displacement,or screw breakage.These findings indicate that the application of a novel guide can shorten the operation time,reduce the number of intraoperative fluoroscopies,improve the accuracy of screw insertion,and shorten the time to return to work.The function of the wrist was satisfactory after the operation.The novel Kirschner wire guide made percutaneous hollow compression screw fixation easier for scaphoid fractures.

OBJECTIVE@#To observe the clinical efficacy of lesion removal, bone grafting, fusion, and external fixation in the treatment of late-stage wrist tuberculosis.@*METHODS@#From October 2015 to May 2019, 25 patients with late-stage wrist tuberculosis were treated using lesion removal, bone grafting, fusion, and external fixation. Among these patients, there were 14 males and 11 females, aged from 40 to 74 years old, with an average age of (60.72±8.45) years old. The duration of the disease ranged from 5 to 24 months, with an average of (11.52±7.61) months. There were 11 cases of left wrist tuberculosis and 14 cases of right wrist tuberculosis, with 5 cases accompanied by sinus formation. Postoperative regular anti-tuberculosis treatment was continued. Visual analogue score (VAS), inflammatory indicators, Gartland-Werley wrist function score, and upper limb function score were observed before and after treatment.@*RESULTS@#All 25 patients were followed up for ranging from 12 to 36 months with an average of (19.7±6.3) months. At the latest follow-up, all wounds were healed satisfactorily, and there was no recurrence of tuberculosis or infection. VAS at one week before operation and three months after operation were (5.16±1.14) score and (1.68±0.80) score respectively. One week before operation and three months after operation, erythrocyte sedimentation rate (ESR) was (44.20±20.56) mm·h-1 and (14.44±1.14) mm·h-1, and C-reactive protein (CRP) was (12.37±7.95) mg·L-1 and (4.3±3.37) mg·L-1. The differences in all three data sets were statistically significant (P<0.01). According to Gartland-Werley wrist function scoring, the scores at one week before operation and one year after operation were (21.32±3.44) and (14.96±1.37) respectively, showed a statistically significant difference (P<0.01). According to the upper limb function score (disabilities of the arm, shoulder, and hand, DASH), the score was (70.52±7.95) at one week before operation and(28.84±2.30) at one year after operation. The difference was statistically significant (P<0.01). At the latest follow-up, no patient had a recurrence of tuberculosis.@*CONCLUSION@#The short-term clinical efficacy of treating wrist tuberculosis with lesion removal, bone grafting, fusion, and external fixation is satisfactory.

ObjectiveTo observe the effect of wrist-hand orthosis combined with modified constraint-induced movement therapy (mCIMT) on upper limb and hand function in patients with stroke. MethodsFrom February, 2022 to December, 2023, 32 patients after stroke in Huashan Hospital, Fudan University were randomly assigned to control group (n = 16) and experimental group (n = 16). Both groups underwent routine rehabilitation, and wore constraint glove almost four hours a day. The experimenal group wore dynamic wrist-hand orthosis four hours everyday, additionally; five days every week, for three weeks. They were evaluated with Wolf Motor Function Test (WMFT), Action Reach Arm Test (ARAT), the strength of gripping, Amount of Use (AOU) and Quality of Movement (QOM) of Motor Activity Log (MAL), Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) before and after treatment, while root mean square ratio of affected/healthy extensor muscle of wrist was measured with surface electromyography ResultsAfter treatment, the scores of WMFT, ARAT, MAL-QOM, HAMA and the root mean square ratio of affected/healthy extensor muscle of wrist improved in both groups (|t| > 2.179, P < 0.05), and the improvement of WMFT score and the strength of gripping was greater in the experimental group than in the control group (|t| > 2.343, P < 0.05); the strength of gripping, the scores of MAL-AOU and HAMD improved in the experimental group (|t| > 2.819, P < 0.05). ConclusionmCIMT assisted with dynamic wrist-hand orthosis could improve upper limb and hand function in stroke patients.
RESUMO
Abstract Objective This study evaluated the epidemiological data and functional outcomes from patients with concomitant distal radial and scaphoid fractures treated in a single center specialized in hand surgery. Functional outcomes analysis used validated instruments. Methods Patients diagnosed with distal radial and scaphoid fractures treated from January 2011 to December 2021 underwent assessments using the Disabilities of the Arm, Shoulder and Hand (DASH), Patient-Rated Wrist Evaluation (PRWE), Visual Analog Scale (VAS) for pain, goniometry, radiographic consolidation, and complications six months after surgery. Results The study included 23 patients, 73.9% men and 26.1% women. Most (56.5%) fractures occurred on the right side, and 43.5% happened on the left side. Treatment of most (56%) distal radial fractures used a locked volar plate. Functional assessment by PRWE resulted in a mean score of 35.9 points (range, 14 to 71 points), while DASH showed a mean score of 37.8 points (range, 12 to 78 points). The mean VAS was 2.33 during activities (range, 0.6 to 6.2). Conclusion Distal radial fractures associated with scaphoid fractures resulted from high-energy trauma, and most patients were males. There was a low rate of complications with surgical treatment, and the patients had satisfactory functional evolution with a low level of pain.

Abstract Objective: This study evaluated sociodemographic and radiographic features of patients with distal radial fractures treated at a trauma hospital in southern Brazil, comparing those treated by hand surgery specialists (group 1) and non-specialists (group 2). Methods: This study consists of a retrospective cohort of 200 patients treated in 2020. After reviewing medical records and radiographs, the following parameters were analyzed: age, gender, trauma mechanism, laterality, associated comorbidities and fractures, fracture classification (AO), radial height, radial inclination, and volar inclination. Comparison of the two groups used the Student t-test, chi-square test, or Fisher exact test. Results: Most subjects were women (54%), sustained low-energy traumas (58%), and were left-handed (53%). Group 1 had a lower mean age (50.2 years); most of their subjects sustained high-energy trauma (54%) and had type C fractures (73%); type A fractures prevailed in group 2 (72%). Radiographs showed a significant difference regarding the mean radial inclination (21.5° in group 1 and 16.5° in group 2 [p < 0.001] in women, and 21.3° in group 1 and 17° in group 2 [p < 0.001] in men) and volar inclination (10.1° and 12.8° in groups 1 and 2, respectively [p < 0.001]). In addition, the absolute number of cases with reestablished anatomical parameters per the three evaluated variables was also significantly different; all parameters were better in group 1. Conclusion: Hand surgeons treated the most severe fractures and had the best radiographic outcomes.

SUMMARY: Distal radius fractures are the most common fractures of the upper limb. The most commonly used method in the repair of these fractures is volar locking plates. Recently, the frequency of removal of volar locking plates after surgery has increased. There are many factors in its reduction. Anatomically, incompatibility of the distal end of the radius with volar locking plates is one of them. In previous studies, different volar cortical angle (VCA) values were found in other races. For this reason, this study aimed to determine the mean values by making VCA measurements of the Anatolian population. The study was designed retrospectively. In the study, measurements were made on computed tomography (CT) images of the distal end of the radius of 53 men and 28 women. Radial width, intermediate volar angle, and radial volar angle were measured in the images. On average, the radius width was 23.35±1.96 mm, and the intermediate volar angle was 26.02±.3.83°, radial volar angle was 24±3.07°. Radial width, intermediate volar angle, and radial volar angle differed significantly by gender (p<0.001). A significant correlation was found between radius width, intermediate volar angle, and radial volar angle values (p<0.001). It has been determined that the Anatolian population has a different VCA value than the European, Asian, and other populations. When using volar locking plates in distal radius fracture surgery, volar locking plates should be selected by considering the average values of the races.
Las fracturas del radio distal son las fracturas más comunes del miembro superior. El método más utilizado en la reparación de estas fracturas son las placas de bloqueo volar. Recientemente, ha aumentado la frecuencia de extracción de placas de bloqueo volar después de la cirugía. Existen muchos factores en su reducción y anatómicamente, la incompatibilidad de la extremidad distal del radio con las placas de bloqueo volar es una de ellas. En estudios anteriores, se encontraron diferentes valores del ángulo cortical volar (VCA) en otras grupos. Por esta razón, este estudio tuvo como objetivo determinar los valores medios, realizando mediciones de VCA de la población de Anatolia. El estudio fue diseñado de manera retrospectiva. En el estudio, se realizaron mediciones en imágenes de tomografía computarizada (TC) de la extremidad distal del radio de 53 hombres y 28 mujeres. En las imágenes se midieron el ancho radial, el ángulo volar intermedio y el ángulo volar radial. En promedio, el ancho del radio fue de 23,35 ± 1,96 mm, el ángulo volar intermedio fue de 26,02 ± 3,83° y el ángulo volar radial fue de 24 ± 3,07°. El ancho radial, el ángulo volar intermedio y el ángulo volar radial difirieron significativamente según el sexo (p<0,001). Se encontró una correlación significativa entre los valores del ancho del radio, el ángulo volar intermedio y el ángulo volar radial (p<0,001). Se ha determinado que la población de Anatolia tiene un valor de VCA diferente al de las poblaciones europeas, asiáticas y otras. Cuando se utilizan placas de bloqueo volar en cirugía de fractura de la extremidad distal del radio, las placas deben seleccionarse considerando los valores promedio de los individuos de diferentes grupos.

SUMMARY: The present study aimed to evaluate wrist (lunate) anatomy in terms of the incidence of lunatum morphology on plain-radiographs among the Anatolian (Turkey) population, accompanied by demographic analysis. We obtained all the patients' data regarding demographical features, diagnosis, and posteroanterior (PA) X-ray imaging. Two radiograph-reviewers repeated the analysis twice, one month later, blinded to their findings before the previous review. The lunatum structure was determined as Type-1 (n:293) and Type-2 (n:207) for each radiograph. Most of the 500 wrists' radiographs [n:293 (58.6 %)] were type-I lunate. The mean age was 36.7±13.3 (range:18-90) years. Sex distribution was as follows: 185 (63.1 %) males to 108 (36.9 %) females. Type-2 lunate was seen in 207 participants (41.4 %). The mean age for type-2 was 41.6±15.2 (18-88) years. 142 (68.6 %) participants were male sex, while 65 (31.4 %) were females. The mean age of subjects with type-I showed a difference with type-II (p=0.007). There was no relationship in terms of sex (p=0.206) between the groups. In the Anatolian region, type-1 lunate was dominant compared to type-2. The incidence rate of lunate type in Anatolian population was similar to the Arab population.
El presente estudio tuvo como objetivo evaluar la anatomía de la articulación radiocarpiana en términos de la incidencia de la morfología del hueso semilunar en radiografías simples entre la población de Anatolia (Turquía), acompañado de un análisis demográfico. Obtuvimos todos los datos de los pacientes con respecto a las características demográficas, el diagnóstico y las imágenes de rayos X posteroanteriores (PA). Dos revisores de radiografías repitieron el análisis dos veces, un mes después, sin conocer sus hallazgos antes de la revisión anterior. La estructura del lunatum se determinó como Tipo-1 (n:293) y Tipo-2 (n:207) para cada radiografía. La mayoría de las 500 radiografías de muñecas [n:293 (58,6 %)] fueron semilunar tipo I. La edad media fue de 36,7±13,3 (rango: 18-90) años. La distribución por sexos fue la siguiente: 185 (63,1 %) hombres y 108 (36,9 %) mujeres. El semilunar tipo 2 se observó en 207 participantes (41,4 %). La edad media para el tipo 2 fue de 41,6±15,2 (18-88) años. 142 (68,6 %) participantes eran del sexo masculino, mientras que 65 (31,4 %) eran del sexo femenino. La edad media de los sujetos con tipo I mostró una diferencia con el tipo II (p = 0,007). No hubo relación en cuanto al sexo (p=0,206) entre los grupos. En la región de Anatolia, el semilunar tipo 1 era dominante en comparación con el tipo 2. La tasa de incidencia del tipo semilunar en la población de Anatolia fue similar a la de la población árabe.

Abstract Objective The study aims to demonstrate an evaluation method to predict the functional success of total wrist arthrodesis (TWA) and assist its indication. Methods A prospective study including ten patients submitted to (TWA) posttraumatic arthritis. Exclusion criteria were patients who lost postoperative follow-up or incomplete information in the medical record. The objective functional assessment (handgrip strength, three-point pinch, lateral pinch and pulp-pulp pinch) and the subjective functional assessment (DASH, PRWE, EVA) were evaluated in 3 different periods: (1) Before surgery without articular anesthesia, (2) Before surgery under articular anesthesia and (3) 12 weeks after the surgical procedure. Results There was an increase in handgrip strength in all three pinches measurements after pain relief, both after joint anesthesia and after the consolidation of the arthrodesis (p < 0.05). In the comparisons between the subjective evaluations (DASH, PRWE and VAS), the patients had better scores in the postoperative evaluation after 12 weeks (p < 0.05). There was no statistical difference when comparing the mean strength values found after anesthesia and after 12 weeks of TWA. Conclusion the outcomes could propose an assessment protocol for patients with indication for TWA, in which patients with good response to intra-articular anesthetic infiltration would benefit from the effects of the surgical procedure.
Resumo Objetivo O estudo tem como objetivo demonstrar um método de avaliação para predizer o sucesso funcional da artrodese total do punho (ATP) e auxiliar na sua indicação. Métodos Um estudo prospectivo incluindo dez pacientes submetidos a ATP por artrite pós-traumática. Os critérios de exclusão foram pacientes que perderam o acompanhamento pós-operatório ou informações incompletas no prontuário. A avaliação funcional objetiva (força de preensão manual, pinça de três pontos, pinça lateral e pinça polpa-a-polpa) e a avaliação funcional subjetiva (DASH, PRWE, EVA) foram avaliadas em 3 momentos diferentes: (1) Antes da cirurgia sem anestesia articular, (2) Antes da cirurgia sob anestesia articular e (3) 12 semanas após o procedimento cirúrgico. Resultados Houve aumento da força de preensão palmar nas três medidas de pinça após o alívio da dor, tanto após a anestesia articular quanto após a consolidação da artrodese (p < 0,05). Nas comparações entre as avaliações subjetivas (DASH, PRWE e VAS), os pacientes tiveram melhores escores na avaliação pós-operatória após 12 semanas (p < 0,05). Não houve diferença estatística ao comparar os valores médios de força encontrados após a anestesia e após 12 semanas de ATP.

In 2013, midpalatal suture maturation stage assessment was proposed for the evaluation of patients before performing maxillary expansion. In this study, we aimed to analyze the association between the midpalatal suture maturation stages assessed by CBCT, according to the method described by Angelieri et al., and other objective methods used to assess skeletal maturation or bone fusion. A computerized database search was conducted using PubMed, Cochrane Library, SciELO, LILACS, Web of Science, and Scopus, without language restriction. Unpublished literature was searched on ClinicalTrials.gov, the National Research Register, and Pro-Quest Dissertation Abstracts and Thesis database. Authors were contacted when necessary, and reference lists of the included studies were screened. Search terms included midpalatal suture, maturation, correlation, diagnostic performance, classification, evaluation, assessment, and relationship. Quality assessment was performed using the Observational Cohort and Cross-Sectional Studies tool developed by the National Heart, Lung, and Blood Institute. Eleven studies met the inclusion criteria. Of all the studies included, 81.9% had fair qualit y and 18.1% good quality, respectively. Eight out of eleven studies assessed the correlation between the midpalatal suture maturation method and the skeletal maturity evaluated by CVM method (Spearman's correlation coefficient: 0.244-0.908). Two out of eleven studies evaluated the correlation between midpalatal suture maturation method and the skeletal maturity assessed by HWM method (Spearman's correlation coefficient: 0.904-0.905) Even though midpalatal suture maturation stage assessment needs an exhaustive training and calibration process, it is a valid method to evaluate skeletal maturation or bone fusion. From a clinical perspective, for patients at CS4, CS5 and CS6, an assessment of the midpalatal suture on CBCT is indicated. A similar assessment should be done in patients at SMI 7-9.
En 2013, se propuso un nuevo método para la evaluación del estadio de maduración de la sutura palatina mediana para la evaluación de los pacientes antes de realizar la expansión maxilar. En este estudio, nuestro objetivo fue analizar la asociación entre las etapas de maduración de la sutura palatina mediana evaluada en CBCT, según el método descrito por Angelieri et al., y otros métodos objetivos utilizados para evaluar la maduración esquelética o la fusión ósea. Se realizó una búsqueda en las bases de datos PubMed, Cochrane Library, SciELO, LILACS, Web of Science y Scopus, sin restricción de idioma. Se buscó literatura no publicada en ClinicalTrials.gov, el Registro Nacional de Investigación y la base de datos Pro-Quest Dissertation Abstracts and Thesis. Se estableció contacto con los autores cuando fue necesario y se revisaron las listas de referencias de los estudios incluidos. Los términos de búsqueda incluyeron sutura palatina mediana, maduración, correlación, rendimiento diagnóstico, clasificación, evaluación, valoración y relación. La evaluación de la calidad se realizó mediante la herramienta de Estudios transversales y de cohortes observacionales desarrollada por el Instituto Nacional del Corazón, los Pulmones y la Sangre. Once estudios cumplieron con los criterios de inclusión. Del total de estudios incluidos, el 81.9% tuvo calidad regular y el 18.1% calidad buena, respectivamente. Ocho de once estudios evaluaron la correlación entre el método de maduración de la sutura palatina mediana y la madurez esquelética evaluada por el método CVM (coeficiente de correlación de Spearman: 0.244-0.908). Dos de once estudios evaluaron la correlación entre el método de maduración de la sutura palatina mediana y la madurez esquelética evaluada por el método HWM (coeficiente de correlación de Spearman: 0.904-0.905). Aunque la evaluación del estado de maduración de la sutura palatina mediana necesita un proceso exhaustivo de entrenamiento y calibración, es un método válido para evaluar la maduración esquelética o la fusión ósea. Desde una perspectiva clínica, para pacientes en CS4, CS5 y CS6, está indicada una evaluación de la sutura palatina mediana en CBCT. Se debe realizar una evaluación similar en pacientes con SMI 7-9.

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.

Abstract Objective To investigate the long-term use of smartphones as a risk factor for the development of morbidities in the wrist and fingers. Methods The present is a descriptive, exploratory study with a quantitative approach based on injury prevalence among one hundred smartphone users of a private university in the state of Pernambuco, Northeastern Brazil. We applied a semi-structured questionnaire and the Boston Carpal Tunnel Questionnaire (BCTQ), as well as the Visual Analog Scale (VAS) and the Finkelstein, Phalen, reverse Phalen, and Tinel signal tests on the wrist. Results The average of the sample was of 22.73 years, with a prevalence of single, right-handed female participants. Most of them had been using smartphones for 5 to 10 years, and 85% reported discomfort in the wrist and fingers while using the device, with numbness as the most prevalent symptom. Most clinical tests were negative, and the Finklestein test showed greater positivity. The BCTQ is composed of a symptom severity scale (S scale) and a functional status scale (F scale): the overall score on the S scale was of 1.61, indicating mild to moderate symptoms, and the F scale revealed that the symptoms did not affect functionality. Conclusion There was a significant correlation between the length of use of smartphones and discomfort in the wrist and fingers; as such, smartphones are a risk factor for the development of morbidities.
Resumo Objetivo Investigar o uso de smartphones em longo prazo como fator de risco para o desenvolvimento de morbidades no nível do punho e dos dedos. Métodos Realizou-se um estudo descritivo, exploratório, de abordagem quantitativa, para a obtenção de medidas de prevalência com cem acadêmicos usuários de smartphones de uma faculdade privada localizada no sertão de Pernambuco. Foram aplicados um questionário semiestruturado e o Questionário de Síndrome doTúnel do Carpo de Boston (Boston Carpal Tunnel Questionnaire, BCTQ, na sigla em inglês), além da Escala Visual Analógica (EVA) e dos testes de Finkesltein, Phalen, Phalen reverso, e sinal de Tinel no punho. Resultados A idade média da amostra foi de 22,73 anos, com prevalência de solteiros, de destros, e do sexo feminino. O tempo de uso do smartphone indicado pela maioria dos participantes era entre 5 e 10 anos, e 85% da amostra relatou já ter sentido desconforto no punho e nos dedos durante o uso do aparelho, sendo a dormência o sintoma mais prevalente. Com relação aos testes clínicos, houve prevalência de resultados negativos, e o de Finklestein apresentou maior positividade. Quanto ao BCTQ, dividido em duas escalas, uma de gravidade dos sintomas (escala G) e uma de estado funcional (escala F), a média geral das pontuações foi de 1,61 na escala G, o que indica sintomas de leve a moderados, já a escala F revelou que os sintomas não afetavam a funcionalidade. Conclusão Foi possível observar uma correlação significativa entre o tempo de uso dos smartphones e a presença de desconforto no punho e nos dedos, o que indica que se trata de um fator de risco para o desenvolvimento de morbidades.

RESUMO
Abstract Chronic distal radioulnar joint (DRUJ) dislocation has been treated historically with complex osteotomies and reconstructive procedures, often resulting in intractable stiffness and loss of function. It is desirable to use a technique of fixation that will not only restore the wrist biomechanics but also be cosmetically appealing to the individual. We present a novel technique of reduction and fixation of a chronically dislocated DRUJ in a 26-year-old male using a minimally invasive approach, with successful restoration of DRUJ function and no postoperative complications.
Resumo Luxação crônica da articulação radioulnar distal (ARUD) foi tratada historicamente com osteotomias complexas e procedimentos reconstrutivos, geralmente resultando em rigidez intratável e perda de função. É desejável usar uma técnica de fixação que não apenas restaure a biomecânica do punho, mas também seja esteticamente atraente para o indivíduo. Apresentamos uma nova técnica de redução e fixação de uma ARUD deslocada cronicamente em um homem de 26 anos, usando uma abordagem minimamente invasiva, com restauração bem-sucedida da função da ARUD e sem complicações pós-operatórias.

Abstract: Scaphoid fractures are a common wrist injury accounting for 2-7% of all adult fractures. Nonunion is described in 5-12% of cases leading to osteoarthritis. Several classifications have been developed focused on this pathology and its complication. We present a case of a 28 years old male patient with a scaphoid fracture and nonunion who spontaneously consolidates without treatment. We performed a literature review to recognize this pathology, its common evolution and possible treatment options.
Resumen: Las fracturas de escafoides son una lesión frecuente de la muñeca y representan de 2-7% de todas las fracturas en adultos. La no unión se describe en 5-12% de los casos y conduce a la osteoartritis. Se han desarrollado varias clasificaciones centradas en esta patología y su complicación. Presentamos el caso de un paciente varón de 28 años con fractura y no unión de escafoides que consolida espontáneamente sin tratamiento. Realizamos una revisión bibliográfica para reconocer esta patología, su evolución habitual y las posibles opciones de tratamiento.
RESUMO
Introducción: Las fracturas del radio distal se encuentran entre las más comunes y deben incrementarse por su relación con el envejecimiento poblacional. Su tratamiento quirúrgico ha aumentado gracias a un mejor conocimiento de la anatomía, la introducción de nuevos implantes y los beneficios de la movilización precoz. Objetivo: Revisar la anatomía regional del radio distal, la articulación de la muñeca y los actuales abordajes quirúrgicos para esta región. Métodos: Se realizó una búsqueda en PubMed con los términos: anatomía del radio distal, anatomía de la muñeca, abordajes quirúrgicos para radio distal, fracturas de radio distal. Se revisaron artículos del servicio ClinicalKey e Hinari. Desarrollo: El extremo óseo distal del radio posee 5 superficies; los tendones y numerosas estructuras vasculonerviosas obligan a un conocimiento profundo. Existen múltiples abordajes quirúrgicos para el adecuado manejo de las fracturas del extremo distal del radio. Conclusiones: Los abordajes quirúrgicos para el radio distal pueden ser volares, radiales y dorsales. La visualización de la superficie articular se logra mejor artroscópicamente. Cada abordaje requiere una comprensión profunda de la anatomía local del radio distal para poder disecar y exponer las fracturas.
Introduction: Fractures of the distal radius are among the most common and they should increase due to their relationship with population aging. Its surgical treatment has increased thanks to better knowledge of the anatomy, the introduction of new implants and the benefits of early mobilization. Objective: To review the regional anatomy of the distal radius, the wrist joint, and the current surgical approaches for this region. Methods: A PubMed search was performed using the terms distal radius anatomy, wrist anatomy, distal radius surgical approaches, distal radius fractures. Articles from the Clinical key and Hinari service were reviewed. Development: The distal bony end of the radius has 5 surfaces, the tendons and numerous neurovascular structures that require in-depth knowledge. There are multiple surgical approaches for the proper management of fractures of the distal end of the radius. Conclusions: The surgical approaches for the distal radius can be volar, radial and dorsal. Visualization of the articular surface is best achieved arthroscopically. Each approach requires a thorough understanding of the local anatomy of the distal radius in order to dissect and expose fractures.
RESUMO
SUMMARY: The ulnar nerve (UN) is the main nerve responsible for innervation of the intrinsic musculature of the hand. It is of great importance to have a deep anatomical knowledge of the UN. The aim of this study is to enrich the knowledge of the UN anatomy at the wrist and provide useful reference information for clinical and surgical applications. In this descriptive cross-sectional study, 44 upper limbs of fresh cadavers were evaluated. The UN, the superficial branch of the ulnar nerve (SBUN), and the deep branch of the ulnar nerve (DBUN) were evaluated. Morphometric variables were measured using a digital caliper, and samples of nervous tissue were taken to evaluate the histomorphometry. Before entering the Guyon's canal, the UN had a diameter of 3.2 ± 0.4 mm. In 36 samples (82 %) the UN presented a bifurcation pattern and in the remaining 8 samples (18 %) a trifurcation was shown. The diameter of the DBUN was 1.9 ± 0.33 mm and that of the SBUN was 1.29 ± 0.22 mm. In the bifurcation patterns, the SBUN had a trunk of 5.71 ± 1.53 mm before bifurcating into the common digital nerve (fourth and fifth fingers) and an ulnar digital collateral nerve (fifth finger). The DBUN had an area of 2.84 ± 0.7 mm2 and was made up of 8 ± 1.4 fascicles and 3595 ± 465 axons. The SBUN area was 1.31 ± 0.27 mm2, it was made up of 6 ± 1.1 fascicles and 2856 ± 362 axons. The reported findings allow the hand surgeon to improve his understanding of the clinical signs of patients with UN pathologies at the wrist level and thus achieve greater precision while planning and performing surgical approaches and dissections.
El nervio ulnar (NU) es el principal nervio responsable de la inervación de la musculatura intrínseca de la mano. Es de gran importancia tener un profundo conocimiento anatómico del NU. El objetivo de este estudio fue enriquecer el conocimiento de la anatomía del NU en la muñeca y proporcionar información de referencia útil para aplicaciones clínicas y quirúrgicas. En este estudio descriptivo transversal se evaluaron 44 miembros superiores de cadáveres frescos. Se evaluó el NU, el ramo superficial del nervio ulnar (RSNU) y el ramo profundo del nervio ulnar (RPNU). Las variables morfométricas se midieron con un caliper digital y se tomaron muestras del nervio para evaluar la histomorfometría. Antes de ingresar al canal del nervio ulnar (canal Guyon), el ONU tenía un diámetro de 3,2 ± 0,4 mm. En 36 muestras (82 %) el ONU presentó un patrón de bifurcación y en las 8 muestras restantes (18 %) se presentó una trifurcación. El diámetro del RPNU fue de 1,9 ± 0,33 mm y el del RSNU de 1,29 ± 0,22 mm. En los patrones de bifurcación, el RSNU presentó un tronco de 5,71 ± 1,53 mm antes de bifurcarse en el nervio digital común (cuarto y quinto dedo) y un nervio digital colateral ulnar (quinto dedo). El RPNU tenía un área de 2,84 ± 0,7 mm2 y estaba formado por 8 ± 1,4 fascículos y 3595 ± 465 axones. El área del RSNU fue de 1,31 ± 0,27 mm2, estaba formado por 6 ± 1,1 fascículos y 2856 ± 362 axones. Los hallazgos reportados permiten al cirujano de mano mejorar su comprensión de los signos clínicos de los pacientes con patologías del NU a nivel de la muñeca y así lograr una mayor precisión en la planificación y realización de abordajes y disecciones quirúrgicas.

Abstract: A spontaneous rupture of the extensor pollicis longus (EPL) tendon after a fracture of the distal radius is a known complication in adults. In contrast, there are a paucity of reports concerning EPL tendon ruptures in children and adolescents. The authors present a case of a spontaneous rupture of the EPL tendon in a 15-year-old girl after a non-displaced distal radius fracture. The patient had no predisposing factors including rheumatoid arthritis or steroid injection. During surgery, the EPL tendon was found to be ruptured at the extensor retinaculum (third compartment). Extensor indicis proprius (EIP) to EPL transfer was performed. At the 18-month follow-up, the patient was asymptomatic and showed satisfactory thumb function, with normal active extension.
Resumen: La rotura espontánea del tendón del extensor largo del pulgar (EPL) tras una fractura distal del radio es una complicación conocida en adultos. En cambio, son escasos los informes sobre roturas del tendón del EPL en niños y adolescentes. Los autores presentan un caso de rotura espontánea del tendón del EPL en una niña de 15 años tras una fractura distal del radio no desplazada. La paciente no presentaba factores predisponentes como artritis reumatoide o inyección de esteroides. Durante la intervención quirúrgica, se descubrió que el tendón del EPL estaba roto a la altura del retináculo extensor (tercer compartimento). Se realizó una transferencia del extensor indicis proprius (EIP) al EPL. A los 18 meses de seguimiento, el paciente estaba asintomático y mostraba una función satisfactoria del pulgar, con una extensión activa normal.
RESUMO
Objective:To investigate the clinical efficacy of wrist-ankle acupuncture combined with rehabilitation for dysphagia caused by achalasia of the cricopharyngeal muscle after stroke.Methods:Sixty patients with dysphagia caused by achalasia of the cricopharyngeal muscle after stroke who received treatment in Wenzhou Hospital of Traditional Chinese Medicine from June 2019 to March 2020 were included in this study. They were randomly divided into a treatment group and a control group ( n = 30). All patients received routine drug treatment and swallowing rehabilitation training. The control group underwent routine acupuncture treatment. The treatment group received wrist-ankle acupuncture based on routine acupuncture treatment. Both groups were treated for 4 consecutive weeks. The clinical efficacy in the two groups was evaluated using the Video Fluoroscopic Swallowing Study (VFSS), Standardized Swallowing Assessment (SSA), and Swallow Quality-of-Life Questionnaire (SWAL-QOL). Results:Before treatment, there were no significant differences in VFSS, SSA, and SWAL-QOL scores between the two groups. After treatment, VFSS, SSA, and SWAL-QOL scores in the treatment group were (8.21 ± 0.77) points, (21.19 ± 1.42) points, (200.24 ± 11.12) points, and they were (6.01 ± 0.36) points, (23.31 ± 1.45) points, and (182.37 ± 12.06) points in the control group ( t = 3.26, 5.50, 6.31, all P < 0.05). Conclusion:Wrist-ankle acupuncture combined with rehabilitation is an effective treatment method for dysphagia caused by achalasia of the cricopharyngeal muscle after stroke. It can alleviate dysphagia and improve quality of life.
