Fracturas inestables de radio distal intra y extraarticulares: análisis comparativo de resultados a mediano plazo del tratamiento quirúrgico con placas volares / Intra- and extra-articular distal radius unstable fractures: comparative analysis of the medium-term results of volar plate surgical treatment

Introducción Comparar los resultados radiológicos y recuperación postoperatoria de la función de la muñeca a mediano plazo en las fracturas inestables extra e intra articulares de radio distal, después de la reducción abierta con abordaje palmar y osteosíntesis con placa volar. Materiales y métodos Estudio de casos y controles en 52 pacientes divididos en los grupos de fracturas extra o intra articulares de acuerdo a la clasificación AO. Las radiografías preoperatorias y postoperatorias fueron evaluadas para determinar la restauración anatómica de la longitud radial, ángulo radial e inclinación palmar del radio. Se evaluó además el resultado, seis meses después de la cirugía, del rango activo de movimiento y la fuerza de agarre, a la vez, que se hizo evaluación del puntaje de QuickDASH. Resultados La edad promedio fue 53,7±16,8 (DE) años; el 63% mujeres. Las fracturas extra articulares fueron más frecuentes en las mujeres, pero las intra articulares presentaron distribución similar por sexo (p=0.023). La fuerza de agarre de la mano operada fue 73.7% y 67.5% de la mano opuesta en las fracturas extra e intra articulares, respectivamente. El puntaje QuickDASH promedio fue 2.36 (DE 2.01) y 4.16 (DE 3.82) en fracturas extra e intra articulares respectivamente (p=0.111). Discusión Para fracturas de radio distal la reducción abierta con abordaje palmar y estabilización con placa volar ofrece resultados funcionales satisfactorios tanto para las fracturas extra articulares como para las intra articulares, con una leve, aunque esperada, ventaja en las primeras debido a su menor complejidad.

Background To examine and compare the radiological results and postoperative recovery of the medium-term wrist function in unstable extra- and intra-articular fractures of distal radius, after open reduction with a palmar approach and osteosynthesis with a volar plate. Materials and methods Retrospective case control study in 52 patients, divided into groups according to the Orthopaedic Association (AO) classification as extra- or intra-articular fractures. The pre-operative and post-operative radiographs were evaluated to determine the anatomical restoration of the radial length, radial angle, and palmar inclination of the radius. The medium-term results of the active range of motion and the grip strength, as well as the Quick DASH score, were evaluated six months after surgery. Results The mean age was 53.7±16.8 (SD) years and 63% were women. Extra-articular fractures were more frequent in women, but intra-articular fractures had a similar distribution by gender (P=.023). The grip strength of the operated hand was 73.7% and 67.5% of the opposite hand in the extra- and intra-articular fractures, respectively. The mean Quick DASH score was 2.36 (SD 2.01) and 4.16 (SD 3.82) in extra- and intra-articular fractures, respectively (P=.111). Discussion For unstable distal radius fractures, open reduction with palmar approach and volar plate stabilisation offers satisfactory functional results for both extra-articular and intra-articular fractures, with a slight, but expected, advantage in the former due to its lesser complexity.

Bilateral Macrodactyly of the Halluces in an Adolescent Girl Corrected with Shortening Osteotomies of the First Metatarsal and the Phalangeal Bones: A Case Report.

CASE: A 14-year-old girl presented with painful high-arched feet and unusual, asymptomatic, bilateral macrodactyly of the halluces. After a year of observation, a surgical reduction was performed because of the psychological effect that the abnormality had on the patient. Bilateral shortening osteotomies of the metatarsal and the proximal phalangeal bones were performed. At 2 months after surgery, complete bone healing and alignment had been achieved. At the 5-year follow-up, we noted fully functional big toes, plantigrade feet, bilateral proper toe formula, and extreme patient satisfaction with the cosmetic results. CONCLUSION: Dual osteotomies for toe shortening in a patient with bilateral nondysmorphic macrodactyly provided appropriate length reduction and satisfactory aesthetic and functional results.
