[Results after minimally invasive therapy of acute scapholunate dissociation]

In 27 cases with acute scapholunate ligament injury, minimal invasive treatment was performed. After closed reduction scapholunate transfixation was achieved by Kirschner wires. Postoperatively, a short-arm cast was applied for six weeks. All patients have been reexamined on average 26 months after operation. Follow-up results have been good concerning clinical examination and patients' satisfaction. Radiological examination has shown recurrence of scapholunate instability in 15 cases. In fact, 11% of the patients had dynamic and 44% static instability at follow-up. Recurrence has been most frequent in cases involving primary static instability. Consequently, these cases should be treated by open reduction. Minimal invasive treatment of acute scapholunate dissociation is not recommended. The therapeutic procedure must be adapted to the different stages of scapholunate ligament injury.
