Abstract
Purpose

To assess the medium-term results of (DVR) fixed-angle anatomic plates in the treatment of unstable distal radius fractures.

Materials and methods

Retrospective study of 93 dorsally displaced unstable distal radius fractures, treated by means of open reduction with a volar approach and DVT plate fixation. Mean age was 46 years and mean follow-up was 13 months. A clinicalfunctional evaluation was carried out for all patients by measuring range of movement, degree of pain, surgical outcomes (using the Gartland–Werley and Green-O’Brien scales) and degree of disability as reflected by the DASH scale. Radiographs were used to assess volar and radial inclination angles as well as radial height, articular step-offs and radiocarpal arthritis. The last X-ray follow-up value obtained was used to carry out a statistical comparison with immediate pre- and post-operative radiographs.

Results

All our fractures but one healed in a mean 8.2-week period. The radiological parameters studied showed that the mean correction achieved was within normal values and now significant variations occurred at the end of follow-up (p≤0.05). Some degree articular step-off persisted in 12 fractures. 73,33% of patients were pain free. The score of excellent and good results were higher than 80% according to the scales used, and the disability index was low (18.32) according to the DASH score.

Conclusions

The use of fixed-angle volar plates with locking screws in a safe and efficient treatment for dorsally displaced instable distal radius fractures. We think these constitute an excellent alternative for the treatment of this kind of injury.

Resumen
Objetivo

Evaluar a medio plazo los resultados de la placa anatómica de ángulo fijo (DVR [distal volar radius]) en el tratamiento de las fracturas inestables del radio distal.

Material y método

Estudio retrospectivo de 93 fracturas inestables, distales, del radio y con desplazamiento dorsal, tratadas mediante reducción abierta por vía volar y osteosíntesis con placa DVR. La edad media fue de 46 años y el seguimiento medio de 13 meses. A todos los pacientes se les realizó evaluación clinicofuncional mediante medición de los rangos articulares, valoración del dolor, medición de los resultados con escalas Gartland- Werley y Green-O’Brien, y del grado de discapacidad a través del DASH (Disabilities of the Arm, Shoulder and Hand). Se realizó evaluación radiográfica de los ángulos de inclinación volar y radial, altura radial, escalones articulares, y artrosis radiocarpiana y se tomó el último control radiológico obtenido para la comparación estadística con las radiografías preoperatorias y postoperatorias inmediatas.

Resultados

Todas estas fracturas, excepto una, consolidaron en un tiempo medio de 8,2 semanas. En los parámetros radiológicos estudiados se obtuvo corrección media dentro de los valores normales y no hubo variación estadísticamente significativa al final del seguimiento (p ≤ 0,05). En 12 fracturas quedó algún grado de escalón articular. El 73,33% de los pacientes estaba libre de dolor. Las tasas tuvieron de excelentes a buenos resultados: superiores al 80% según las escalas aplicadas y un bajo índice de discapacidad (18,32) según el DASH.

Conclusiones

El empleo de placas volares de ángulo fijo con tornillos bloqueados es un tratamiento seguro y eficaz para fracturas distales del radio, inestables y con desplazamiento dorsal. Los autores de este artículo creen que es una excelente alternativa en el tratamiento de este tipo de lesiones.
