Lunectomy and tendon tamponade

Dislocation of the crescent bone, even if it is rotated 180 °, ischemic necrosis may not necessarily occur, because the nourishing blood vessels located in the palmar ligament are mostly continuous, and the crescent bone can still obtain blood supply from this. Therefore, closed or open reduction is the first choice for the treatment of meniscus dislocation. The indications for this operation should be strictly controlled: for lunial dislocations where the dorsal metacarpal ligament is ruptured, the connection with the surrounding bones is completely lost, and the dislocation of the lunar bone that cannot be reduced by incision, the old lunar dislocation with difficult reduction, For obvious injuries, lunar excision can be considered. Articular cartilage damage is severe dislocation of the lunar bone. Proximal carpal resection and carpal fusion can be performed.
