ABSTRACT
Lateral closing wedge osteotomy is a treatment for Kienbock’s disease. It is one of the most fre-quently used treatment options, which has been reported with relatively good long-term results. However, the results about the treatment are still controversial in some literatures and some key mechanisms are still not clear. The objective of the current study was to study the biomedical mechanism of the treatment. A finite element model was developed based on the geometry of car-pal bones. Various situations including inclination angle changes by cutting the radial with 0°, 5°, 10° and 15° osteotomy angles were studied. The effectiveness of the treatment was also studied for the carpal structure with abnormal positions of the lunate bone. The results show that the ef-fectiveness of the stress reduction with the angle depends on many situations such as the initial morphology of the carpal structure.
