Introducción

Se presenta la evaluación retrospectiva de 6 casos de fracturas intraarticulares conminutas del calcáneo tratadas con reducción abierta, reconstrucción de la forma del calcáneo, injerto óseo autólogo y artrodesis subastragalina primaria fijada con un tornillo canulado de 7 mm, en el período comprendido entre noviembre de 1997 y agosto de 2002.

Material y método

Todos los pacientes eran trabajadores cubiertos por el sistema argentino de riesgos laborales. La decisión para tal técnica fue tomada preoperatoriamente en tres casos de fracturas tipo IV de Sanders mediante la evaluación de cortes tomográficos coronales, e intraoperatoriamente en tres casos de fracturas tipo III de Sanders cuando, bajo visión directa, se constató compromiso del cartílago articular que afectaba al tercio o más de la carilla calcánea posteroexterna.

Resultados y conclusiones

Todas las artrodesis consolidaron dentro de los primeros 4 meses de tratamiento. La dehiscencia de la herida con necrosis angular del colgajo dorsal del abordaje fue la principal complicación (50% de los casos). No se observó artrosis de articulaciones vecinas. Los pacientes retornaron a sus anteriores empleos antes de los 6 meses de evolución. El seguimiento promedio fue de casi 30 meses. La puntuación promedio según la American Orthopaedic Foot & Ankle Society (AOFAS) fue de 76 puntos.

Introduction

The retrospective evaluation of six cases of intraarticular comminuted calcaneal fractures is presented. They were treated with open reduction, reconstruction of the calcaneal shape, autologous bone grafting and a primary subtalar arthrodesis fixed with a single cannulated 7 mm screw, in the period between November 1.997 and August 2.002.

Material and methods

All these cases were funded by the Argentine National Insurance System. The decision to use this technique was taken preoperatively in three cases of Sanders Type IV fractures using the evaluation of coronal CT views, and intraoperatively in three cases of Sanders Type III fractures when, under direct testing, a compromise of the articular surface that affected one third or more of the posterior facet was verified.

Results and conclusions

All the arthrodeses consolidated during the first four months of treatment. Wound dehiscence with angular necrosis of the dorsal flap of the incision was the first complication (50% of cases). Arthrosis of neighboring joints were not observed. The patients returned to their previous jobs within six months. The average AOFAS score was 76 points.
