title: Radial osteotomies for teenage patients with Kienböck disease.
abstract: Age seems to affect the efficacy of radial osteotomies for Kienböck disease. We questioned whether an osteotomy would produce acceptable results in teenagers. We retrospectively identified 11 patients (six males and five females) between 11-19 years of age who were treated with radial osteotomies for Kienböck disease. Preoperatively, three patients had Lichtman Stage II disease, two patients had Stage IIIA disease, and six patients had Stage IIIB disease. Two patients with zero or positive ulnar variance had lateral closing wedge osteotomies, and nine patients with negative ulnar variance had radial shortenings. All patients were evaluated clinically and radiographically. At a mean followup of 50 months, 10 of 11 patients were free from pain, and the remaining one patient had moderate wrist pain during strenuous activity. All patients except one, who had Stage IIIB disease, had an excellent clinical outcome. Radiographic improvement, indicating lunate revascularization, was seen for eight patients. Despite Stage IIIB disease, radial osteotomies produced excellent clinical results in five of six teenage patients. The current results indicate that radial osteotomies are effective in improving not only short-term clinical outcomes, but also radiographic findings in teenage patients with Kienböck disease.
