Materials and Methods: Retrospective case series of 11 patients with a mean age of 45 years were treated by the senior author 7 months after SL injury. Surgical repair or reconstruction of the scapholunate interosseous ligament is normally required to prevent long-term complications 3, namely proximal migration of the capitate between the scaphoid and lunate with a resultant degenerative disease known as SLAC wrist (scapholunate advanced collapse). procedures should be considered. INVESTIGATORS' WORKSHOP (IWIW). A scapholunate angle of greater than 60° on a lateral radiograph is indicative of SL dissociation and a dorsal intercalate segmental instability (DISI) pattern. Another reason is that compression forces transmitted through the capitate has a tendency to separate the scaphoid and lunate. They keep our bones in alignment and they prevent our bones from wobbling all over the place. ADVERTISEMENT: Supporters see fewer/no ads.

The scapholunate is an interosseous carpal ligament that provides stability to the proximal carpal row. injury. This ligament is in the middle of the wrist between the scaphoid and lunate . The goal of the reconstruction is to limit the widening of the scapholunate distance and palmar radioscaphoid-capitate, scaphoid capitate, and anterolateral scapho-trapezio-trapezoid ligaments. It appears to provide the best results in patients with less It also allows for flexibility and range of motion. The typical pattern of scapholunate dissociation consists of: Although "scapholunate dissociation" is a descriptive term, it is used synonymously with its primary pathophysiologic correlate, scapholunate interosseous ligament (SLIL) injury. As for repair techniques, their diversity must not hide the fact that a biomechanical and physiological principle is involved and must be identified. This book presents the findings of an expert group in the field of wrist pathology. Mayfield et al.
