Abstract
The natural history of an untreated isolated scapholunate interosseus ligament injury remains unclear, although it is commonly assumed that patients continue to suffer with pain, stiffness and weakness of the wrist and ultimately develop secondary osteoarthritis (SLAC wrist). In this study, we evaluated the clinical condition of 11 patients with an arthroscopically proven interosseus scapholunate ligament injury, but without any radiological signs of either DISI deformity or scapholunate gapping, who had declined further treatment at an average follow-up of 7 years. Whilst there was on going pain and functional limitation in all cases, there was no rapid progression to degenerative change (SLAC wrist).
