Mastery Trigger: Check the "Mark Skill as Read" under each Step. […] radius malunion is the most common cause may be purely ligamentous or have associated ulnar and radial styloid fractures Associated conditions intracarpal injury (scapholunate or lunotriquetral ligament) acute carpal tunnel syndrome compartment syndrome Prognosis [orthobullets.com] Prognosis: Volar dislocation more severe than dorsal. Scapholunate dissociation (SLD) is the most common type of carpal instability. It is the most common instability pattern because the intercarpal motion during flexion and extension cross at the scapholunate interface.

Scapholunate instability is the most frequent pattern of carpal instability occurring separately and as part of other wrist disorders. New to Orthobullets? Join for free. Outcomes of scapholunate intercarpal ligamentoplasty for chronic scapholunate dissociation: a prospective study in 26 patients. Scapholunate dissociation.

It consists of dorsal, proximal and palmar segments that bridge the scaphoid and lunate.

The scapholunate is an interosseous carpal ligament that provides stability to the proximal carpal row. It consists of dorsal, proximal and palmar segments that bridge the scaphoid and lunate. When the ligament complex tears, the scaphoid tends to flex while the lunate extends, creating translational and rotational instability between the two.

It consists of dorsal, proximal and palmar segments that bridge the scaphoid and lunate. When the ligament complex tears, the scaphoid tends to flex while the lunate extends, creating translational and rotational instability between the two.
