Assessment of results of opponensplasty.

One hundred and fifty-six opponensplasties carried out on 115 patients at Anandaban Hospital between 1987 and 1997 were reviewed. In most cases a flexor digitalis superficialis opponensplasty was performed. The outcome was assessed by measuring the finger to which the thumb could obtain a pinch grip, the gap between the thumb and little metacarpophalangeal joints, and the satisfaction of the patient. The objective assessments demonstrated excellent or good results in 89%. Good or fair patient satisfaction was obtained in 93%. Early complications were seen in seven cases (4%). Objective measurements of outcome and patient satisfaction were not always in agreement, indicating that objective measures do not adequately assess the success of surgery from the patient's perspective. We thus conclude that subjective measurements of results are an important measure of success and should be included in the evaluation of surgical results.
