Arthroscopic Debridement for Treatment of Chronic Dynamic Scaphoid Instability.

 There is a paucity of information on minimal surgical intervention for the treatment of chronic dynamic scaphoid instability (CDSI) that will achieve an acceptable mid-term result.  We hypothesize that by following a debride-first-then-wait protocol, some patients with CDSI can be treated with arthroscopic debridement alone and avoid a reconstructive procedure.  We performed a retrospective, longitudinal study from January 2008 to December 2018 of all patients diagnosed with CDSI and treated with arthroscopic debridement of the scapholunate interosseous ligament.
