[Scapholunate dissociation. Results of ligament suture and ligament-plasty]

The diagnosis of scapholunate ligament rupture is frequently missed. Untreated, it will lead to carpal collapse and arthrosis of the wrist, and ultimately to scapholunate advanced collapse (SLAC-wrist). We report the results of 20 patients treated either by direct suture or reconstruction of the ligament with a follow-up of three to five years after surgery. The operation was performed between 0.5 and 120 months (suture 2.6 months, reconstruction 28 months) after the original trauma. The results of direct repair were superior to ligament reconstruction. In our experience, direct ligament repair was only possible up to four to six months after trauma, this study emphasizes the importance of early diagnosis and treatment by anatomical reposition of scapholunate ligament rupture.
