Radial collateral ligament repair of the thumb: long-term outcomes and predictive factors of postoperative deficits

摘要: The thumb’s radial collateral ligament (RCL) plays an important role in stabilizing the first metacarpophalangeal joint (MCP-1). RCL injuries are rare and treatment recommendations inconsistent current literature. aim of this study was to report on long-term outcomes following surgical repair thumb tear identify prognostic risk factors for failure. Patients with from 10/1998 10/2019 were included present retrospective single center cohort study. In follow-up visits, participants assessed regarding pain, range motion strength as well disability shoulder, arm hands (DASH), Short-Form 36 (SF36) questionnaires. Finally, predictive postoperative deficits identified. 43 patients fulfilled inclusion criteria. Median age 43.5 years (range 18–80 years). most frequent mechanism injury a fall or impact. Bony avulsions identified 46.5% (20/43). Time surgery 12 days (0–276 days). One Stener-like lesion observed intraoperatively among our patients. After repair, MCP-1 stable every patient. Mean time 5.3 years (1 month 17 years). Persistency pain reported by 11 Postoperative averaged score 3.75 DASH 44.96 SF36, respectively. average grip pinch 32.7 kg 8.37 kg, Predictive delay > 3 weeks (OR 10.72, p 0.017) palmar subluxation prior 8.86, 0.019). Long-term has proven that enables patient regain adequate stability minimizes disability. persistency after joint.
