ABSTRACT

Antecedentes y objetivo: El abordaje posterior percutáneo del húmero se ha descrito utilizando una placa LCP de 4,5mm. A pesar de que las placas rectas han demostrado buenos resultados, estas no han sido diseñadas para adaptarse a la metáfisis del húmero distal. El objetivo de este estudio es probar la hipótesis nula de que no existen diferencias en la extracción de la osteosíntesis después de una MIPO posterior utilizando una placa recta comparado a una placa anatómica. Materiales y métodos: Se incluyeron retrospectivamente en 2 instituciones pacientes mayores de 18 años que habían sufrido una fractura diafisaria de húmero distal tratados mediante técnica percutánea posterior con una placa bloqueada y con un seguimiento mínimo de 12 meses. Los pacientes se dividieron en: grupo 1 (placa recta LCP de 4,5mm) y grupo 2 (placa de forma anatómica de 3,5mm). Durante el postoperatorio se reportó la evaluación clínica y radiológica, así como la necesidad de retirar el implante debido al dolor. Resultados: Sesenta y siete pacientes cumplieron los criterios de inclusión. Veintisiete pacientes en el grupo 1 y 40 en el grupo 2. No se perdió ningún paciente durante el seguimiento. Dentro del grupo 1, el 18% (IC 95%: 6-38%) de los pacientes requirieron extracción del implante, mientras que en el grupo 2 esta incidencia fue del 0% (IC 95%: 0-9%) (p 0,009). No hubo diferencias estadísticas entre las medidas de resultado informadas por los pacientes; todas las fracturas consolidaron. Conclusión: Los resultados de nuestro estudio demostrarían que el uso de placas LCP rectas de 4,5mm comparado a las placas anatómicas LCP de 3,5mm en MIPO posterior de húmero genera mayores molestias y, por lo tanto, conllevan un incremento en el riesgo de extracción del implante de un 18%.(AU)


Purpose: Posterior MIPO approach in the humerus has been described by using a 4.5mm LCP plate. Although straight plates have shown good results, they have not been designed to adapt to the distal humeral metaphysis. The goal of the study was to test the null hypothesis that there is no difference in hardware removal after posterior MIPO with either a straight or a pre-contoured plate. Methods: Patients older than 18 years, who had suffered mid-distal humeral shaft fracture, were treated by a posterior MIPO technique with a locking plate and had a minimum of 12-month follow-up were retrospectively included. Patients were separated into: group 1 (LCP 4.5mm straight plate); and group 2 (3.5mm anatomically shaped plate). Clinical and radiological evaluation were performed in the postoperative period. Patient-reported outcomes and the need of hardware removal because of pain were assessed. Results: Sixty-seven patients fulfilled the inclusion criteria. Twenty-seven patients in group 1 and 40 in group 2. No patient was lost to follow-up. There were no statistical differences between in patient reported outcomes measures. All the fractures healed. Within group 1, 18% (95%CI: 6-38%) of the patients required implant removal while in group 2 this incidence was 0% (95%CI: 0-9%) (P 0.009). Conclusion: These results suggest that the use of a 4.5mm LCP compared to an anatomical 3.5mm LCP in posterior MIPO of the humerus generates greater discomfort and therefore leads to a 18% increase in the risk of implant removal.(AU)

ABSTRACT

OBJECTIVE: To report our experience in the treatment of 2-3 fragment proximal humeral fractures using a minimally invasive technique that involves an angular-stable locking implant and find out the factors affecting patients outcomes. MATERIAL AND METHODS: Descriptive, prospective study of the case series type. Twenty-two patients, 13 females and 9 males, were operated on between February 2010 and August 2012. Mean age was 50.8 years (24-82 years). Patients were placed in a beach-chair position. A lateral acromial approach was used under fluoroscopic guidance. Minimal follow-up period was 24.3 months (11-32). Follow-up consisted of X-ray review to check for bone healing and avascular necrosis, and functional assessment using the Constant-Murley scale. RESULTS: Bone healing occurred in all cases at 6 months. There were no cases of avascular necrosis. Two patients had varus healing (109º), and two had plate impingement. The functional assessment score according to the Constant-Murley scale was 68.8. There were no associated neurologic lesions. CONCLUSIONS: Fixation of proximal humeral fractures with a minimally invasive technique using locking plates represents a valid surgical approach. The avascular necrosis rate was low and early rehabilitation was possible in patients with poor bone quality.


OBJETIVO: Dar a conocer nuestra experiencia en el tratamiento de las fracturas de húmero proximal de 2 a 3 partes con técnica de mínima invasión mediante el uso de un implante con estabilidad angular bloqueado e investigar los factores que afectan los resultados de los pacientes. MATERIAL Y MÉTODOS: Estudio descriptivo y prospectivo tipo serie de casos. De 22 pacientes fueron intervenidos 13 mujeres y nueve hombres en el período comprendido entre Febrero de 2010 y Agosto de 2012. El rango de edad media fue 50.8 años (24-82 años). Se hizo un abordaje acromial lateral con el paciente en posición de silla de playa bajo visión fluoroscópica. El tiempo de seguimiento mínimo fue de 24.3 meses (11-32). El seguimiento se hizo mediante revisión de radiografías para la consolidación y necrosis avascular y la valoración funcional de la escala de Constant. RESULTADOS: En todos los casos se observó consolidación de la fractura a los seis meses. No se detectaron casos con necrosis avascular. Dos pacientes mostraron consolidación en varo (109o). Dos pacientes presentaron pinzamiento por la placa. El resultado funcional según la escala de valoración de Constant-Murley fue de 68.8 puntos. No hubo lesiones neurológicas asociadas. CONCLUSIONES: La fijación con técnica mínimamente invasiva para las fracturas de húmero proximal con placas bloqueadas es una alternativa válida como tratamiento quirúrgico. La incidencia de necrosis avascular fue baja y se permitió una rehabilitación temprana en pacientes de mala calidad ósea.

ABSTRACT

Objetivo: Las fracturas de radio distal mal consolidadas con angulación dorsal, pérdida de la altura radial y desviación cubital pueden ser tratadas y corregidas por un abordaje palmar, evitando la morbilidad sobre el aparato extensor. Material y metodología: Tratamos 19 pacientes con una mala consolidación de una fractura distal del radio por vía palmar con una placa en «T» palmar de ángulo fijo. Fueron evaluadas radiográficamente y con una escala funcional (DASH). Resultados: Todos los resultados fueron buenos o excelentes. Conclusión: Proponemos la osteotomía palmar, técnicamente más sencilla, para corregir la mala consolidación (AU)


Objetive: The malunion of the distal radius with dorsal angulation, loss of the radial height and ulnar deviation can be treated with a palmar approach avoiding the morbidity of the extensor mecanism an injury associated with dorsal devices. Material and method: A palmar osteotomy, technically simple to correct the malunion realized in 19 patients, were evaluated with radiological parameters and applied the functional scale of DASH. Results: All the results were good or excellent . Conclusion: The precise position of anatomically fixed angle «T» palmar plate fit the characteristics of the distal radius and facilitates the reduction of the malunion fragment (AU)
