title: Scapholunate Dissociation.
abstract: Wrist injuries are a common complaint in the emergency setting. Any disruption of the anatomy of the carpal bones can impair hand function, leading to pain, weakness, and complications. One of the most common forms of carpal bone instability is scapholunate dissociation. This injury can lead to significant morbidity including avascular necrosis, impaired healing, limited function, and arthritis. These diagnostic findings may be subtle, thus identifying high-risk mechanisms of injury, and clinical manifestations will assist the emergency practitioner with early diagnosis and treatment of this high-risk injury.
