Abstract

|
Scapholunate dissociation is the most common cause of the wrist pain and instability and typically results from scapholunate interosseous ligament (SLIL) injury. It is difficult for surgeons to diagnose the SLIL injury due to its complex anatomy and biomechanics. The natural history of the SLIL injury is still not fully understood as most of the SLIL injuries are not detected in their acute stage. Careful physical examination and radiologic evaluation are essential aspects of SLIL injury diagnosis. We should consider five conditions to evaluate SLIL injuries: the integrity of the dorsal SLIL, the healing potential of the disrupted ligament, the alignment of the scaphoid, the reducibility of the carpal malalignment, and the cartilage condition. In this review, the stages classified based on these conditions and the current treatments according to each stage will be described in detail.
