Capitolunate arthrodesis with compression screws.

Scapholunate dissociation or scaphoid pseudarthrosis may lead to wrist osteoarthritis. When osteoarthritis concerns the midcarpal joint, proximal row carpectomy is not possible. Only 4-corner or capitolunate arthrodesis may be indicated. In this procedure, pseudarthrosis was frequently described in literature. However, in these series, fixation was performed with pins or staples. Type and position of the device are important to obtain carpal bones fusion. The efficiency of compression screws has been validated in scaphoid fracture or pseudarthrosis. Moreover, the axial position of the screws, parallel to the physiological wrist loads, may participate to improve bone fusion. Therefore, we present our technique of capitolunate arthrodesis with compression screws fixation through a dorsal approach.
