Incidence & Clinical Significance of Osteolysis Following PEEK Suture Anchor Use in Hand & Wrist Surgery

Description

This prospective observational study evaluates the incidence & clinical significance of osteolysis following polyetheretherketone (PEEK) suture anchor use in hand & wrist surgery. Building on a pilot study, it focuses on patients undergoing hand & wrist surgeries with suture anchor implantation over the past 10 years. Patients are grouped by anchor composition: PEEK, metallic, or bioabsorbable. The investigators hypothesize that PEEK anchors will show significantly greater osteolysis than metallic or bioabsorbable anchors. Furthermore, among all patients with osteolysis, the investigators expect no statistically significant differences in patient-reported outcomes (PROs), post-op complications, or revision surgery rates, regardless of anchor type. Lastly, for patients with ulnar collateral ligament (UCL) thumb injuries, the investigators hypothesize that osteolysis presence will not correlate with increased UCL laxity upon valgus stress testing compared to the nonoperative thumb.
