To determine whether there is any motion loss associated with the 1,2 intracompartmental supraretinacular artery (ICSRA) bone graft to the dorsal scaphoid. The null hypothesis is that placement of a vascularized bone graft in the dorsal scaphoid does not lead to a significant change in range of motion.
Seven fresh-frozen cadaveric upper extremities were examined. Simulated 1,2 ICSRA bone grafts were harvested and placed into a dorsal trough made in the proximal scaphoid. Wrist motion measurements were performed before and after 1,2 ICSRA bone graft implantation.
There were no significant changes in wrist motion following 1,2 ICSRA bone graft implantation.
Properly placed 1,2 ICSRA vascularized bone grafts for treatment of proximal scaphoid nonunions do not by themselves cause loss of wrist motion.
Loss of motion following the treatment of proximal scaphoid nonunions with properly placed 1,2 ICSRA vascularized bone grafts are due to factors other than the bone graft itself.
确定将1,2骨间室上视网膜动脉（ICSRA）骨移植至舟骨背侧是否会导致任何运动功能丧失。无效假设是带血管蒂骨移植至舟骨背侧不会导致活动范围发生显著变化。
检查了7个新鲜冷冻的尸体上肢。获取模拟的1,2 ICSRA骨移植块并将其植入舟骨近端制作的背侧骨槽中。在植入1,2 ICSRA骨移植块前后进行腕关节运动测量。
植入1,2 ICSRA骨移植块后，腕关节运动无显著变化。
正确放置的用于治疗舟骨近端骨不连的1,2 ICSRA带血管蒂骨移植本身不会导致腕关节运动功能丧失。
用正确放置的1,2 ICSRA带血管蒂骨移植治疗舟骨近端骨不连后出现运动功能丧失是由骨移植本身以外的因素导致的。
