Abstract
Introduction and purpose

In the last few years, there has been increased aggressiveness in the treatment of distal radius fractures by means of internal fixation. Locked plates prevent metaphyseal collapse even in the presence of osteoporotic or comminuted bone; they also maintain reduction and allow early motion. Nevertheless, there is as yet not enough evidence as to what may be the best way of treating this fracture. Our purpose is to assess our functional results and the complications that can arise from the use of distal radius locked plates.

Materials and methods

This is a retrospective study of 145 unstable distal radius fractures treated by means of a locked volar plate, with a mean follow-up of 28 months. AO (Association for the Study of Osteosynthesis) and Fernandez’ classifications were used to assess the presence of osteoporosis, need for a graft, difference between healthy and fractured hand in terms of mobility, the radiographic measurements and the functional PRWE (Patient-Rated Wrist Evaluation) test and any potential complications. A statistical analysis was carried out.

Results

95 patients were analyzed. Mean PRWE score was 13 points. A significant relation was found between motion and functional result. A graft was used in 3 patients and there were no cases of pseudoarthrosis or metaphyseal collapses. Eight percent of patients presented with some serious complication (algodystrophy, chronic pain, malunion).

Conclusions

Locked plates can be regarded as an alternative to the treatment of unstable distal radius fractures. They provide good functional results and few complications, they minimize the need for grafting and they allow early mobilization even in the presence of osteoporotic and comminute bone.

Resumen
Introducción y objetivos

En los últimos años se está observando un aumento en la intensidad del tratamiento de la fractura de radio distal derivado hacia la fijación interna. Las placas bloqueadas evitan el colapso metafisario aun con el hueso osteoporótico o conminuto, mantienen la reducción y permiten una movilidad temprana. Sin embargo, todavía no hay suficiente evidencia de cuál es el mejor método de tratamiento para esta fractura. Nuestro objetivo es evaluar nuestro resultado funcional y las complicaciones con el uso de las placas bloqueadas de radio distal.

Material y métodos

Estudio retrospectivo sobre 145 fracturas inestables de radio distal tratadas mediante placa volar bloqueada, con un seguimiento medio de 28 meses. Se usó la clasificación AO (Asociación para el Estudio de la Osteosíntesis) y la clasificación de Fernández. Se evaluó la presencia de osteoporosis, la necesidad de injerto, la diferencia de movilidad entre la muñeca sana y la muñeca fracturada y las medidas radiográficas, así como el test funcional PRWE (Patient-Rated Wrist Evaluation) y las complicaciones. Análisis estadístico.

Resultados

Se revisó a 95 pacientes. La puntuación media del PRWE fue de 13 puntos. Se encontró una relación significativa entre la movilidad y el resultado funcional. Se utilizó injerto en 3 pacientes y no hubo casos de seudoartrosis o colapsos metafisarios. El 8% de los pacientes presentó alguna complicación seria (algodistrofia, dolor crónico o consolidación viciosa).

Conclusiones

Las placas bloqueadas se presentan como una alternativa para el tratamiento de las fracturas inestables de radio distal, proporcionan buenos resultados funcionales, pocas complicaciones, minimizan la necesidad de aporte de injerto y permiten una movilización temprana aun con hueso osteoporótico o conminuto.
