Operative treatment with radial shortening in Kienböck's disease.
Eighty-eight patients underwent radial shortening for Kienböck's disease. Prerequisites for surgery were radiographic studies positive for Kienböck's disease without evidence of radiocarpal arthritis and wrist pain unrelieved by conservative management. Thirty-nine patients were evaluated by subjective questionnaire at a mean postoperative follow-up of 86 months (range: 24-188 months). Following surgery, a significant decrease was noted in pain severity, frequency, and duration. Functional status improved postoperatively, with the most significant gains noted in the following activities: opening jars, opening car doors, carrying bags, and shoveling. Only 3 of 34 patients employed outside the home were unable to return to their original occupations due to their wrist problems. Seventy-six patients were evaluated by physical examination at a mean postoperative follow-up of 31 months (range: 3-87 months). Objective evaluation by physical examination revealed a significant improvement in wrist motion and grip strength. Seventy-seven patients underwent radiographic evaluation at a mean postoperative follow-up of 31 months (range: 3-180 months). A significant progression in Lichtman stage of Kienböck's disease was noted despite the favorable subjective findings and high satisfaction ratings. Thirty-six of 39 patients stated they would undergo the surgery again. The long-term data demonstrate radial shortening in patients with stage II-IIIA Kienböck's disease provides substantial improvement over preoperative status.
