STATISTICAL ANALYSIS ON FUNCTIONAL AND RADIOGRAPHIC RESULTS AFTER USE OF LOCKED VOLAR PLATE FOR FRACTURES OF THE DISTAL RADIUS

Abstract

Objectives: To evaluate the functional results from using a fixed-angle locked volar plate for treating fractures of the distal extremity of the radius, using the DASH (disorders of the arm, shoulder and hand) questionnaire and its radiographic correlation with the Lidström classification.

Methods: Thirty patients with unstable fractures of the distal extremity of the radius were evaluated after they had undergone a surgical procedure consisting of open reduction and internal fixation using a fixed-angle locked volar plate, at the Military Police Central Hospital of Rio de Janeiro between 2008 and 2009. The results were assessed based on range of motion, DASH protocol scores and radiographies with the Lidström classification.

Results: The mean age of the patients in the study was 51 years. The mean DASH score was 11.9 points. It was observed that the radiographic findings did not influence the DASH score. It was found that flexion, pronation, supination and radial deviation correlated with the DASH score.

Conclusions: The study showed that subjective functional outcomes using the DASH protocol, obtained from using a locked volar plate to treat fractures of the distal extremity of the radius, are influenced by the range of motion, and especially by the flexion, supination, pronation and radial deviation of the wrist after surgery. There is no correlation between the radiological parameters of either the normal or the operated radius, and the subjective functional outcomes assessed using the DASH protocol.

Preoperative radiographs on the wrist in (A) anteroposterior view and (B) lateral view, showing fracture of the distal extremity of the radius extending to the distal radioulnar joint, with associated fracturing of the styloid process of the ulna. (C and D) osteosynthesis was performed using a 2.4 mm locked volar plate on the radius, with fixation using a Kirschner wire in the ulna. This was removed 12 weeks after its placement. Twenty-three months after the first surgical procedure, a new radiological control was performed in (E) anteroposterior view and (F) lateral view.
