Scapholunate ligament injuries may lead to scapholunate instability
and wrist osteoarthritis. Many surgical techniques have been described to repair
these injuries. The goal of our study is to assess the clinical results after
capsulodesis with the scaphotriquetral ligament for scapholunate instabilities.
METHODS: Twenty-eight patients, 22 men and six women, were operated for
scapholunate instability between January 2006 and December 2008. The average age
was 37.8 years, and the average time between trauma and surgery was 9.9 months.
The scaphoid shift test was present in 26 patients. All patients underwent static
and dynamic X-rays of the wrist and scan. A capsulodesis with scaphotriquetral
ligament was performed in all patients. RESULTS: At 24 months follow-up, a 13
degrees significant decreased of wrist range-of-motion was noted. The strength
was significantly improved after surgery. The wrist stability was improved in 26
patients. Concerning pain, a significant reduction was noted with Analogical
Visual Scale after surgery (p<0.005). Twenty-one patients returned to their
previous work. Complications were reflex dystrophy in one patient and wrist
infection in one patient. CONCLUSION: Many techniques were described for
treatment of scapholunate injuries, from the simple scapholunate ligament suture
to partial wrist arthrodesis. Capsulodesis with scaphotriquetral ligament
improves grip strength, decreases wrist instability and pain with a slight lost
of range-of-motion.
