Fracturas supracondíleas humerales pediátricas. Comparación de dos técnicas de reducción / Pediatric humeral supracondylar fractures. Comparison of two reduction techniquesin

Resumen Objetivo: Analizar los resultados de la técnica quirúrgica de colocación de clavillos Kirschner forma lateral versus cruzada en el manejo de las fracturas supracondíleas de húmero en pacientes pediátricos. Metodología: Se captaron a todos los pacientes con fractura supracondílea humeral en edad pediátrica que requirieron intervención quirúrgica, y posteriormente fueron evaluados a las 24 horas y 6 meses posterior al tratamiento quirúrgico para observar y comparar las diferencias entre cada técnica quirúrgica utilizada, tomando en cuenta las complicaciones agudas y tardías que se presentaron mediante un análisis con la prueba de Mann-Whitney. Resultados: Para el presente estudios se evaluaron 44 pacientes pediátricos de los cuales 70% eran hombres y 30% mujeres, en quienes se presentaron complicaciones nerviosas y angulares sin importancia significativa alguna con el sexo y edades de los pacientes, siendo la afección del nervio cubital la de mayor frecuencia con 33% en la colocación de forma cruzada. Al realizar la comparativa con discriminación de variables se obtiene que la colocación de forma lateral presenta menos complicaciones posquirúrgicas tempranas y tardías y que tales no se deben al azar. Limitaciones o implicaciones: En el presente estudio no se incluyó el tipo de daño mecánico que provoca este tipo de fractura, ni se consideró el ángulo de Baumann. Otra limitación inherente en la población pediátrica es la habilidad del explorador para detectar un déficit neurológico, especialmente en pacientes de edad temprana dado a que los reportes de una exploración física siempre son subjetivos. Además, dada la limitación en cuanto a los detalles del mecanismo específico de daño, se puede subestimar el número de daños provocados por mecanismos de alta energía. Originalidad y valor: Su importancia radica en que ambas técnicas quirúrgicas fueron realizadas por los mismos cirujanos y que se trata de un estudio en población mexicana, siendo un aporte para la literatura de este país. Conclusión: Ambas técnicas quirúrgicas presentan resultados posquirúrgicos con casos de lesión nerviosa, deformidad angular, dolor y edema persistente, pero la que los presenta en menor frecuencia es la técnica de colocación de clavillos Kirschner en forma lateral, además de causar una significancia estadística en cuanto a la disminución de presentar cubito valgo en el seguimiento tardío de los pacientes.

Abstract: Objective: To analyze the results of the surgical technique placement of Kirschner pins lateral versus crossed in the management of supracondylar fractures of the humerus in pediatric patients. Methodology: All pediatric patients with humeral supracondylar fracture who required surgical intervention and were subsequently evaluated 24 hours and 6 months after surgical treatment to observe and compare the differences between each patient. surgical technique used. Taking into account the acute and late complications that occurred, through an analysis with the Mann-Whitney test. Results: For the present studies, 44 pediatric patients were evaluated, of whom 70% were men and 30% women, in whom nerve and angular complications presented without any significant importance with the sex and age of the patients, with ulnar nerve involvement being the most frequent with 33% in cross placement. When carrying out the comparison with discrimination of variables, it is obtained that the placement laterally presents fewer early and late post-surgical complications and that such are not due to chance. Or the present study, it is considered that a placement of Kirschner pins laterally regardless of the member, age, gender or classification; leads to better post-surgical results. Limitations or implications: In the present study, the type of mechanical damage that causes this type of fracture was not included, nor was the Baumann angle considered. Another limitation inherent in the pediatric population is the ability of the examiner to detect a neurological deficit, especially in young patients since reports of a physical examination are always subjective. Furthermore, given the limited details of the specific damage mechanism, the number of damages caused by high-energy mechanisms may be underestimated. Originality or value: Its importance lies in the fact that both surgical techniques were performed by the same surgeons and that it is a study in the mexican population, being a contribution to the literature of this country. Findings or conclusions: Both surgical techniques present post-surgical results with cases of nerve injury, angular deformity, pain and persistent edema, but the one that presents them less frequently in the technique of placement of Kirschner pins laterally, in addition to causing statistical significance in terms of the decrease of presenting cubitus valgus in the late follow-up of the patients.

Meta-analysis of open reduction and internal fixation versus total elbow arthroplasty for distal humeral fracture in the elderly / 中国组织工程研究

BACKGROUND: The most common surgical procedure for the treatment of distal humeral fracture in the elderly is open reduction and internal fixation and total elbow arthroplasty. There is still a lack of systematic evaluation of the efficacy between the two methods, and further research is needed to better guide clinical work. OBJECTIVE: To compare the clinical efficacy of open reduction and internal fixation combined with total elbow arthroplasty in the treatment of elderly patients with distal humeral fractures. METHODS: The computer was used to retrieve information in databases such as PubMed, The Cochrane Library, EMBASE, Science Direct, CNKI, Wanfang, and VIP. An observational cohort study or randomized controlled trial was performed in the study of open reduction and internal fixation/total elbow arthroplasty for the treatment of elderly patients with distal humeral fractures. The search period was 1998-2018. Studies were read and screened; data were extracted and the quality of the study was assessed by two persons independently. Data analysis was performed using RevMan 5.3. RESULTS AND CONCLUSION: (1) A total of 10 studies were included in 1 069 patients. (2) Meta-analysis results showed that total elbow arthroplasty group was superior to the open reduction and internal fixation group in the incidence of total complications (OR=1.67, 95%C/: 1.19-2.35, P=0.003), Mayo elbow performance score at the last follow-up (MD=-12.68, 95%C/: -16.60 to -8.77, P 0.05). (4) These results confirmed that the total complication rate of the total elbow arthroplasty group was lower than that of the open reduction and internal fixation group, and the elbow joint function was better than that of the open reduction and internal fixation group. For elderly patients with distal humeral fracture, the degree of osteoporosis is different, and the articular surface is difficult to be effectively reset. The treatment of total elbow arthroplasty should be considered.

How Difficult Is It to Surgically Treat AO-C Type Distal Humerus Fractures for Inexperienced Orthopedic Surgeons?

PURPOSE: Twenty early surgical management cases of distal humerus type-C fractures were analyzed. MATERIALS AND METHODS: This study analyzed 20 early patients, who received surgical management of distal humerus type-C fractures, and could be followed-ups for more than one year between March of 2013 and May of 2015. The operative time, bone union time, and elbow range of motion were analyzed. The Mayo's functional score was used to evaluate their postoperative function. The primary and secondary complications of each patient immediately after each of their surgery were also reviewed. RESULTS: All patient groups achieved bone union within an average period of 16.4 weeks. Based on the Mayo functional score, 6, 10, and 4 patients scored excellent, good, and fair, respectively. The average range of motion was a flexion contracture of 14.5° with a follow-up improvement averaging 120.7°. Six patients received nine revision operations due to major and minor complications. Two patients received revision fixation from an inadequate fixating power, and another patient received an ulnar nerve transposition. Other complications included olecranon osteotomy site displacement, superficial operational site infection, and pin loosening. CONCLUSION: Distal humerus fractures of the AO-C type can cause a range of complications and has a very high rate of revision due to its difficult nature of surgical manageability. Therefore, it is imperative for a surgeon to expect various complications beforehand and a careful approach to their postoperative rehabilitation is essential.

Artroplastía total de codo para el tratamiento de fracturas de húmero distal en pacientes mayores de 65 años / Total elbow arthroplasty for distal humerus fractures in patients older than 65 years old

Objetivo: Comunicar los resultados clínico-radiológicos del tratamiento de las fracturas de húmero distal con prótesis total de codo en pacientes >65 años. Materiales y Métodos: Estudio retrospectivo en dos centros quirúrgicos. Criterios de inclusión: pacientes con fractura de húmero distal, >65 años, operados con prótesis total de Coonrad-Morrey y seguimiento >1 año. Se incluyeron 21 pacientes (20 mujeres), edad promedio: 79 años. Según la clasificación AO, 13 C3, siete C2 y una A2. Todos fueron operados sin desinserción del aparato extensor. Seguimiento promedio: 40 meses. Resultados: La flexo-extensión fue de 123-17°, arco de movilidad de 106° (80% con respecto al lado sano). Dolor según la escala analógica visual: 1 punto. El puntaje de la Clínica Mayo promedio fue 83: resultado excelente (8 pacientes), bueno (11 pacientes), regular (1 caso) y malo (1 caso). El puntaje DASH promedio fue de 24. No hubo aflojamientos en 13 pacientes. Se produjeron nueve complicaciones: dos pacientes fueron operados nuevamente por desgaste del polietileno, uno operado otra vez al mes de la cirugía para la recolocación del perno de ensamble, dos parestesias del nervio cubital, una falsa vía intraoperatoria, un hematoma de la herida que necesitó de un colgajo braquial y dos aflojamientos protésicos. Conclusiones: El tratamiento de las fracturas de húmero distal con prótesis total de codo en pacientes >65 años puede ofrecer una opción terapéutica razonable, pero las indicaciones deben limitarse a fracturas complejas donde la fijación interna puede ser precaria, en pacientes con osteoporosis y con baja demanda funcional.

Objective: To report the clinical-functional results of humeral distal fracture treatment with total elbow prosthesis in patients older than 65 years. Methods: Retrospective study performed in two surgical centers. Inclusion criteria: patients with humeral distal fractures, >65 years, operated on with Coonrad-Morrey prostheses, and with a follow-up >1 year. Twenty-one patients were included (20 women) with an average age of 79 years. According to AO classification: 13 type C3 fractures, 7 C2 and 1 A2. All patients were operated on without disinsertion of the extensor mechanism. Average follow-up: 40 months. Results: Flexion-extension: 123-17°, with a total arc of mobility of 106° (80% of the contralateral side). Pain according to visual analogue scale was 1. The Mayo Clinic score was 83 points, results were excellent (8 patients), good (11 patients), regular (one case) and bad (one case). Average DASH score was 24 points. No loosening of the implants was evidenced in 13 patients. Nine complications were reported: 2 reoperations for polyethylene wear, one early decoupling of the prosthesis, 2 ulnar nerve paresthesia, one patient presented a false intraoperative via, one hematoma that needed a local flap and 2 loosening of the prosthesis. Conclusions: Treatment of humeral distal fractures with total elbow arthroplasty in patients older than 65 years may be a good therapeutic option, but indications must be limited to patients with complex fractures, bad bone quality, with osteoporosis and low functional demands.
