Functional results of the Darrach procedure: a long-term outcome study.
PURPOSE:
To assess long-term functional outcome after ulnar head excision for distal radioulnar joint dysfunction with prior or concomitant wrist trauma. We hypothesized that long-term outcomes would reflect good functional results with satisfactory pain relief.
METHODS:
A retrospective chart review identified patients who had undergone the Darrach procedure for traumatic or posttraumatic distal radioulnar joint (DRUJ) pathology. We assessed subjective outcomes using a visual analog scale questionnaire to assess pain, wrist stability, and overall satisfaction. We evaluated objective functional outcomes using the Quick Disabilities of the Shoulder, Arm, and Hand and Patient-Rated Wrist Evaluation measures. Final radiographs were compared with preoperative x-rays to investigate the effect of possible ulnar impingement syndrome (convergent instability).
