Radial Nerve Supracondylar Block Versus Fracture Hematoma Block. Comparison of Their Efficacy in Cases of Fractures of the Distal Third of the Radius.

Objective The present study compares the analgesic efficacy of two techniques to perform non-surgical reduction: fracture hematoma block and radial nerve supracondylar block. Methods Forty patients with fractures of the distal third of the radius, who required reduction, were selected in a quasi-randomized clinical trial to receive one of the anesthetic techniques. All patients signed the informed consent form, except for those who did not wish to participate in the study, had neurological injury, had contraindication to the procedure in the emergency room, or with contraindication to the use of lidocaine. To measure analgesia, the numerical pain rate scale was used at four different moments: preblock, postblock, during reduction, and after reduction; then three differences were calculated: the first between before and after blocking; the second between during reduction and after blockade; and the third between before blocking and after reduction. Results The fracture hematoma and supracondylar block groups showed the following mean values, respectively: 3.90 (1-10) and 3.50 (-6-10) in difference 1; 4.35 (-5-10) and 5.00 (-3-10) in difference 2; and 4.65 (1-10) and 3.80 (-3-10) in difference 3. Conclusion Both techniques proved to be efficient for analgesia, with mild superiority of hematoma block, but without statistical significance.

Resumo Objetivo O estudo compara a eficácia analgésica de duas técnicas para realizar redução incruenta: o bloqueio de hematoma da fratura e o bloqueio supracondilar de nervo radial. Métodos Quarenta pacientes com fraturas do terço distal do rádio, que necessitassem redução, foram selecionados em um ensaio clínico quasi-randomizado, para receber uma das técnicas anestésicas. Todos os pacientes assinaram o termo de consentimento ou assentimento, com exceção daqueles que não desejassem participar do estudo, tivessem lesão neurológica, com contraindicação ao procedimento na sala de emergências, ou com contraindicação ao uso da lidocaína. Para aferir a analgesia foi utilizada a escala numérica da dor em quatro momentos distintos: pré-bloqueio, pós-bloqueio, durante a redução e após a redução; em seguida, foram calculadas três diferenças: a primeira entre antes e após o bloqueio; a segunda entre durante a redução e após o bloqueio; e a terceira entre antes do bloqueio e após a redução. Resultados Os grupos do bloqueio de hematoma de fratura e bloqueio supracondilar apresentaram respectivamente os seguintes valores médios: 3.90 (1-10) e 3.50 (-6-10) na diferença 1; 4.35 (-5-10) e 5.00 (-3-10) na diferença 2; e 4.65 (1-10) e 3.80 (-3-10) na diferença 3. Conclusão As duas técnicas se provaram eficientes para analgesia, com discreta superioridade do bloqueio de hematoma, mas sem significância estatística.

TREATMENT OF THORACOLUMBAR FRACTURES BY CLOSED REDUCTION VIA A PERCUTANEOUS SOLID PEDICLE SCREW.

Objectives: Investigate the effect of closed reduction and per- cutaneous pedicle screw fixation in treating thoracolumbar fractures. Methods: This retrospective study analyzed 12 cases of single-segment thoracolumbar spine fractures without spinal cord and nerve injury at our department from March 2016 to September 2017. Patients were treated with closed reduction, percutaneous reduction, and internal fixation with solid pedicle screws. The operation time, intraoperative blood loss, anterior vertebral body height ratio (AVHR), Cobb angle (CA) of sagittal kyphosis, and VAS of back pain were determined and statistically compared. Results: The average operation time was 147.2 ± 45.6 min, and the average intraoperative bleeding was 67.8 ± 34.2 mL. All fractured vertebrae were completely reduced, their height was restored, and kyphosis was corrected. The average follow-up period was 10.6 ± 2.7 months, with significant improvements seen in the AVHR, CA of sagittal kyphosis, and VAS score (P < 0.01). One case had a broken rod after three months, and another had a postoperative infection. All the patients achieved bony healing. Conclusion: The treatment of thoracolumbar fractures by closed reduction and internal fixation with a percutaneous solid pedicle screw is simple, effective, and economical. Level of Evidence VI; Therapeutic Study, Case Series .

Objetivo: Investigar o efeito da redução incruenta e da fixação com parafuso de pedículo percutâneo no tratamento das fraturas toraco- lombares. Métodos: Este estudo retrospectivo analisou 12 casos de fraturas toracolombares com segmento único sem lesão medular ou neural, encontrados no departamento dentro do período de março de 2016 a setembro de 2017. Os pacientes foram tratados com redução fechada e fixação interna com parafusos de pedículo percutâneo. O tempo de operação, a perda sanguínea intra-operatória, a relação da altura do corpo vertebral anterior (AVHR), o ângulo de Cobb (CA) da cifose sagital e a EVA relativa à dor nas costas foram determinados e comparados estatisticamente. Resultados: O tempo médio da operação foi de 147,2±45,6 min, com sangramento intraoperatório médio de 67,8±34,2 mL. Todas as vértebras fraturadas foram com- pletamente reduzidas, suas alturas foram restauradas e a cifose foi corrigida. O período médio de acompanhamento foi de 10,6±2,7 meses, apresentando melhorias significativas observadas no AVHR, CA da cifose sagital e pontuação VAS (P <0,01). Um caso teve uma haste quebrada após 3 meses, e outro paciente apresentou uma infecção pós-operatória. Todos os pacientes alcançaram a recuperação óssea. Conclusão: O tratamento das fraturas toracolombares por redução fechada com fixação interna pelo parafuso de pedículo percutâneo é simples, eficaz e econômico.

DEVELOPMENT OF ORTHOPEDIC SIMULATOR TO PRACTICE CLOSED REDUCTION OF PEDIATRIC FRACTURES OF THE MIDDLE THIRD OF FOREARM.

In the current scenario of medical education, a trend of using models and simulators to train operational skills, especially in the practice of basic orthopedic techniques, is growing. This form of teaching allows academics to maximize learning opportunities and contributes to improving the quality of care for their future patients. However, the realistic simulation has high costs as a major limitation. Objective: To develop a low-cost orthopedic simulator for practicing pediatric forearm reduction skills in the preclinical setting. Methods: A model of an arm and forearm with a fracture in the middle third was developed. Orthopedists, residents, and medical students evaluated the simulator's ability to reproduce fracture reduction. Results: The simulator had a significantly lower cost than the others in the literature. The participants agreed that the model had a good performance, and that the manipulation was consistent with the reality of reducing closed pediatric forearm fracture. Conclusion: The results suggest that this model can be used to teach orthopedic residents and medical students the skill of closed reduction of fractures in the middle third of the forearm. Level of Evidence III, Case Control Study.

Luxação dorsal complexa da articulação metacarpofalangeana dos dedos longos: relato de caso e revisão da literatura / Complex dorsal dislocation of the metacarpophalangeal joint of the long fingers: case report and literature review

As luxações dorsais da articulação metacarpofalangeana dos dedos são lesões raras, vistas com mais frequência em pacientes jovens, secundárias a trauma por hiperextensão forçada do dedo na mão que estende. São classificadas como simples, quando a redução fechada é possível; ou complexas, quando a redução por métodos fechados não é possível devido à interposição de estruturas periarticulares. É importante distinguir entre uma luxação simples e uma complexa porque sua abordagem e tratamento são diferentes. O objetivo deste estudo é atualizar a abordagem clínica e as diferentes técnicas cirúrgicas utilizadas no tratamento das luxações complexas. Foi realizada uma revisão bibliográfica sobre a luxação dorsal metacarpofalangeana dos dedos longos, excluindo os do polegar, incluindo o Medline (interface PubMed), SciELO e bancos de dados acadêmicos do Google. Todos os artigos revisados concluem que as tentativas de redução incruenta nesses tipos de lesões costumam ser malsucedidas e levar a complicações adicionais. A redução cirúrgica aberta é o método de escolha, permitindo a recuperação anatômica articular com o menor risco de complicações. A imobilização pós-operatória com uma tala de travamento dorsal é recomendada por duas semanas, seguida por reabilitação por terapia ocupacional, esperando-se uma amplitude de movimento normal em seis semanas. A baixa frequência somada ao desconhecimento do médico emergencista ao realizar a manobra de redução pode, muitas vezes, levar à transformação de um simples deslocamento em complexo, tornando-o irredutível e lesionando estruturas adjacentes, por isso, acreditamos ser fundamental conhecer o manejo desta lesão.

Dorsal dislocations of the metacarpophalangeal joint of the fingers are rare injuries that are seen more frequently in young patients secondary to trauma due to forced hyperextension of the finger on the extending hand. They are classified as simple when closed reduction is possible, or complex when reduction by closed methods is not possible given the interposition of peri-articular structures. It is important to distinguish between a simple and complex dislocation because their approach and treatment differ. The objective of this study is to update the clinical approach and the different surgical techniques used in the treatment of complex dislocations. We conducted a bibliographic review on metacarpophalangeal dorsal dislocation of the long fingers, excluding those of the thumb, including the Medline (PubMed interface), SciELO and academic google databases. All the articles reviewed conclude that attempts at closed reduction in these types of injuries are often unsuccessful and often lead to additional complications. Open surgical reduction is the method of choice, allowing joint anatomical recovery with the lowest risk of complications. Postoperative immobilization using a dorsal locking splint is recommended for two weeks followed by rehabilitation by occupational therapy, expecting a normal range of motion at six weeks. The low frequency added to the ignorance of the emergency physician when performing the reduction maneuver can often lead to transform a simple dislocation into a complex one, making it irreducible and injuring adjacent structures, which is why we believe it is essential to know the management of this injury.

Características epidemiológicas de las fracturas supracondíleas de húmero en niños y adolescentes

Introducción: Las lesiones traumáticas del codo son muy frecuentes, sobre todo en niños y adolescentes. Algunas de ellas son de difícil tratamiento y se asocian a complicaciones. De ellas, las fracturas supracondíleas del húmero son una de las más frecuentes. Objetivo: Describir las características epidemiológicas de un grupo de pacientes con esta enfermedad traumática. Métodos: Se realizó un estudio observacional descriptivo en 56 pacientes menores de 18 años atendidos en el Hospital Pediátrico Provincial Dr. Eduardo Agramonte Piña de la provincia Camagüey desde el primero de enero de 2018 al 31 de diciembre de 2021 con un total de 48 meses. Resultados: La razón sexo masculino-femenino de los 56 pacientes fue de 3,3 a 1, codo izquierdo-derecho de 1,9 a 1 y zona rural urbana de 2,2 a 1. El promedio de edades en general fue de 7,5 años. La estadía hospitalaria promedio fue de 4,8 días. El mecanismo de extensión fue el hallazgo más frecuente, así como las fracturas grado III. Los meses de enero y julio en conjunto con los días del jueves, viernes y domingo son los que presentan la mayor cantidad de pacientes. La reducción cerrada y fijación percutánea con alambres de Kirschner fue el método más empleado en esta enfermedad traumática. Conclusiones: Las fracturas supracondíleas del humero en el niño son más frecuentes en el sexo masculino y el codo izquierdo. El promedio de edades en el sexo masculino es mayor que en el femenino. Las zonas rurales aportan la mayor cantidad de pacientes. El tratamiento más empleado es el quirúrgico y las complicaciones inmediatas son infrecuentes.

Introduction: Traumatic injuries of the elbow are very frequent, some of them are difficult to treat and are associated with complications, of which supracondylar fractures of the humerus are one of the most frequent. Objetive: To describe the epidemiological behavior of a group of patients with this traumatic disease. Methods: A descriptive observational study was carried out in patients treated at the Dr. Eduardo Agramonte Piña Provincial Pediatric Hospital in the city of Camagüey from January 1st, 2018 to December 31st, 2021 with a total of 48 months. Results: the male-female sex ratio of the 56 patients was 3.3 to 1, the left-right elbow was 1.9 to 1, and the urban rural area was 2.2 to 1. The average age in general was 7.5 years. The average hospital stay was 4.8 days. The extension mechanism was the most frequent finding, as well as grade III fractures. The months of January and July together with the days of Thursday, Friday and Sunday are the ones with the largest number of patients. Closed reduction and percutaneous fixation with Kirschner wires was the most used method in this traumatic entity. Conclusions: Supracondylar fractures of the humerus in children are more frequent in males and in the left elbow. The average age of males is higher than that of females. Rural areas provide the largest number of patients. The most used treatment is surgery and immediate complications are infrequent.

Bridging versus Nonbridging Dynamic External Fixation of Unstable Distal Radius Fractures in the Elderly with Polytrauma: A Randomized Study.

Background Despite the high prevalence of unstable distal radius fractures (DRFs), there is no consensus regarding the optimal method and treatment timing, especially for elderly patients with multiple associated injuries. Purpose This study aimed to compare the grip strength achieved with two different methods for definitive dynamic external fixation of DRFs in elderly patients with polytrauma operated on within the first 24 hours. Methods In this prospective randomized trial, 35 patients were assigned to undergo definitive external dynamic fixation of DRFs using the nonbridging (group A) or bridging (group B) method. The grip strength, range of motion (ROM), Disabilities of the Arm, Shoulder and Hand (QuickDASH) outcome measure, visual analog scale (VAS) score for pain, and radiographic characteristics were evaluated at 6 and 12 months. Results At 12 months, no significant between-group difference was observed with respect to grip strength. All patients showed results in the third or fourth quartiles. The mean ROMs were 96.94 and 96.38% and the mean QuickDASH scores were 3.53 and 3.85 in groups A and B, respectively. The VAS scores were 1.60 and 1.85 in groups A and B, respectively. The overall complication rates were 13.3 and 15% in groups A and B, respectively. Initial fracture reduction was maintained in 86.67 and 95% of the patients in groups A and B, respectively. Conclusions Both bridging and nonbridging external definitive dynamic fixation proved safe and reliable for the treatment of unstable DRFs in elderly patients with polytrauma. The grip strength results in both groups predicted the restoration of ability in elderly patients to perform activities of daily living independently.

Fracturas en niños: experiencia en un centro de alta complejidad del suroccidente Colombiano / Fractures in children: experience in a tertiary referral hospital in South west Colombia

Resumen Introducción: Es importante conocer las características demográficas y clínicas de las fracturas en niños para mejorar las estrategias de prevención y tratamiento en estos pacientes. Objetivos: Describir las fracturas en niños y sus características epidemiológicas. Metodología: Estudio tipo corte transversal desde enero 2014 hasta diciembre 2017. Pacientes menores de 18 años que consultaron por fracturas a una clínica en Colombia fueron incluidos. Se incluyeron datos demográficos, lugar donde ocurrió el trauma, huesos fracturados y tipo de tratamiento. Se evaluó la distribución por género y grupo etario. La fuente de información fue la historia clínica. Se utilizaron medidas de tendencia central y dispersión para agrupar los datos. Se calculó la incidencia de fracturas por cada 1000 niños/ año. Este estudio recibió aval del comité de ética de la institución. Resultados: Hubo 2436 niños fracturados, 65.6% (n=1597) ocurrieron en hombres. La mayoría fueron entre 6-11 años (40.7%, n=991), luego entre 12-17 años (36.4%, n=887) y finalmente, menores de 6 años (22.9%, n=558). La localización de la fractura más frecuente entre 0-5 años fue el húmero (30.6%, n=171), seguido por el radio (29%, n=162) y la clavícula (15.9%, n=89); entre 6-11 años fue el radio (45.2%, n=448), seguido por el húmero (18%, n=178) y el cúbito (16.6%, n=165); y entre 12-17 años fue el radio (34.6%, n=307), seguido por los huesos de la mano (22.7%, n=201) y los huesos del pie (10.8%, n=96). Requirieron manejo quirúrgico 30.9% de los niños fracturados (n=752). La incidencia de fracturas fue de 29.7/1000 niños por año. Conclusión: Las fracturas en niños se presentan con mayor frecuencia en el género masculino. Los huesos fracturados varían dependiendo del grupo etario, con un porcentaje importante del radio en todos los grupos. La mayoría se manejan de forma conservadora.

Abstract Introduction: It is important to know the demographic and clinical characteristics of fractures in children to improve prevention and treatment strategies in these patients. Objectives: To describe fractures in children and their epidemiological characteristics. Methodology: Cross-sectional study performed between January 2014 and December 2017. Patients under 18 years old with fractures who consulted to a hospital in Colombia were included. Demographic data, the location where the trauma occurred, fractured bones and type of treatment were included. Age and gender distribution were analyzed. Medical records were the source of information. Central tendency and dispersion measures were used to group the data. Incidence of fractures per 1000 children / year was calculated. This study received approval from the institution's ethics committee. Results: There were 2436 children with fractures, 65.6% (n=1597) occurred in males. Most fractures were in children between 6-11 years old (40.7%, n=991), followed by 12-17 years old (36.4%, n=887) and finally by children under 6 years old (22.9%, n=558). For the group under 6 years, most fractures occurred in humerus (30.6%, n=171), followed by radius (29%, n=162) and clavicle (15.9%, n=89); between 6-11 years old it was in radius (45.2%, n=448), followed by humerus (18%, n=178) and ulna (16.6%, n=165); and between 12-17 years it was in radio (34.6%, n=307), followed by bones of the hand (22.7%, n=201) and bones of the foot (10.8%, n=96). Surgical treatment was required in 30.9% (n=752) of the patients. The incidence of fractures was 29.7/1000 children per year. Conclusions: Fractures in children occur more frequently in males. The fractured bones differ depending on the age group; however, radius fractures represent an important proportion in all groups. Most fractures in children are treated in a conservative manner.

Desrotación interfragmentaria y reducción por vía percutánea de la fractura supracondílea de húmero desplazada / Interphragmental debridement and percutaneous reduction of displaced humeral supracondylar fracture

La fractura supracondílea de húmero tiene una alta incidencia en la primera década de la vida. Representa el 3-16 % de todas las fracturas en niños, solo superada por la fractura distal del radio; además constituye el 53-67 % de las fracturas del codo en este grupo de edad. La magnitud del desplazamiento de los fragmentos, la severidad de las lesiones de partes blandas y la posibilidad de complicaciones neurovasculares, la convierten en una lesión grave que requiere tratamiento de urgencia. En determinados casos las condiciones locales de la fractura impiden la manipulación adecuada de los fragmentos, por lo que la reducción no se logra de la manera correcta y la fijación es inestable, haciéndose necesaria una intervención quirúrgica para alcanzar la reducción. En este artículo se expone un nuevo método que consigue la reducción anatómica y permite la fijación estable por vía percutánea. Además, se muestran los resultados obtenidos en dos casos clínicos en los que se aplicó dicho método.

Supracondylar humerus fracture has a high incidence in the first decade of life. It represents 3-16% of all fractures in children, only surpassed by radius distal fracture; it also constitutes 53-67% of elbow fractures in this age group. The magnitude of the fragments displacement, the severity of soft tissue lesions and the possibility of neurovascular complications, make it a serious injury requiring emergency treatment. In certain cases the fracture local conditions the prevent the fragments adequate manipulation, so the reduction is not achieved in the correct way and the fixation is unstable, requiring surgical intervention to achieve reduction. In this article a new method is presented that achieves the anatomical reduction and allows stable fixation by percutaneous way. In addition, the results obtained in two clinical cases in which this method was applied are shown.
