Treatment of chronic scapholunate instability according to the functional demand of the wrist.

Scapholunate instability is the most common form of carpal instability. Complete scapholunate ligamentous complex failure can lead to pain, reduced functional performance, and scapholunate advanced collapse if untreated. The goal of surgery for chronic scapholunate instability (diagnosed later than 6 weeks) before onset of osteoarthritis is to correct the scapholunate instability in order to reduce pain while limiting loss of motion and protecting against osteoarthritis-related collapse in the long-term.

Mini TightRope® suture button indications for thumb basal joint arthritis.

Our aim was to explore the different indications of the Mini TightRope® suture button whether during first-line treatment or secondary surgery of thumb carpometacarpal osteoarthritis (OA). The indications for this new device are presented and discussed based on our own small case series and published data. Twenty-one patients treated with the Mini TightRope® were included in a prospective study.

Dorsal intercarpal ligament capsulodesis: a retrospective study of 120 patients according to types of chronic scapholunate instability.

The purpose of this study was to assess the results of dorsal intercarpal ligament capsulodesis (Mayo technique) for cases of chronic scapholunate instability and to specify the indications according to the severity of instability. A retrospective analysis was conducted and examined dorsal intercarpal ligament capsulodesis procedures performed for chronic scapholunate instability without intercarpal or radiocarpal arthritis. One-hundred and twenty patients were examined by an independent observer (48 predynamic, 48 dynamic and 24 static scapholunate instabilities).
