Abstract
Lateral closing wedge osteotomy is a treatment for Kienbock’s disease. It is one of the most frequently 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 cur-rent study was to study the biomedical mechanism of the treatment. A finite element model was developed based on the geometry of carpal bones. Various situations in-cluding inclination angle changes by cutting the radial with 0?, 5?, 10? and 15? osteot-omy 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 effectiveness of the stress reduction with the angle depends on many situations such as the initial morphology of the carpal structure.
Highlights
IntroductionKienbock’s disease is the osteonecrosis of the lunate bone [1]
The lunate bone is a carpal bone in the human hand
As the minimum principal stress detonates the maximum value of the compression stress under the compression load in the models, the minimum principal stress was compared for model 1 with osteotomy angles of 0 ̊, 5 ̊, 10 ̊ and 15 ̊
Summary
Kienbock’s disease is the osteonecrosis of the lunate bone [1] This disease was firstly termed by Robert Kienböck, an Austrian radiologist, in 1910 and was believed to be the consequence of the surrounding soft tissue trauma [2] [3]. The aetiology and the progression history of the disease still remain unclear, the disease seems to be more frequently related to a biological vascular issue for blood flow affecting the lunate [1]. It might be affected by many factors such as morphological variations of carpus bones and trauma.
