title: [Scaphotriquetral capsulodesis for scapholunate instability].
abstract: OBJECTIVE
  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° 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.
  
  
  CONCLUSIONS
  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.
