{Abstract}: Background  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. Purpose  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. Patients and Methods  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. In all cases, a debride-first-then-wait protocol was followed that included a predetermined wait period after arthroscopic debridement, giving the patient a chance to experience possible symptom improvement. This approach integrated the patient's perceived wellness into the decision-making process. All wrists that remained symptomatic or experienced recurrence of symptoms were treated with a reconstructive procedure. The wrists were divided into two groups: arthroscopic debridement only (ADO) and reconstructive procedure (RP). Results  Seventy-nine wrists (72 patients) of 191 consecutive wrist arthroscopies met the inclusion criteria. The ADO group consisted of 43 wrists (54%). An average of 6.3 years later (range: 2-11 years), these patients remained satisfied with the results of the arthroscopic debridement and did not want further treatment. The RP group included 36 wrists (46%) with 91.7% of reconstructive surgeries occurring within 6 months of the arthroscopy. With a mid-term follow-up, 75% of Geissler grade II ligament tears, 48% of grade III tears, and 39% of grade IV tears were successfully treated with arthroscopic debridement alone and avoided a reconstructive surgery. Conclusion  By adopting a debride-first-then-wait protocol, some patients with CDSI can be treated with a more limited intervention, arthroscopic debridement. In this series, 54% of wrists with CDSI avoided a reconstructive surgery for an average of 6.3 years. Type of Study / Level of Evidence  Case Series, Level IV.
