The surgical treatment of a series of 11 Kienbock patients by lunate core decompression method

Kienbock disease is characterized by avascular necrosis of the lunate bone. Without treatment, it is usually progressive. While many factors may predispose to Kienbock's disease, it is likely caused by a combination of repetitive loading, vascular risk and mechanical predisposition. Treatments therefore have been designed to decrease compressive loading of the lunate, to prevent lunate collapse, and to allow lunate revascularization. There has been suggested different treatments, no treatment has ever been proved successful and the rate of surgical complication is relatively high. In this study we performed a new surgical method in the treatment of Kienbock disease
