Outcomes after Rotation Scarf with Akin Osteotomy for Severe Hallux Valgus
Research Square (Research Square)(2021)
Abstract
Abstract Background: Hallux valgus is one of the most common foot deformities. Surgical treatment is the optimal choice for moderate to severe hallux valgus deformity. Rotation scarf with Akin osteotomy has become increasingly popular. The purpose of our study is to evaluate the long-term outcomes of rotation scarf with Akin osteotomy on severe hallux valgus. Methods: We conducted a retrospective study of patients with hallux valgus who underwent surgery using rotation scarf with Akin osteotomy in our hospital between June 2014 and January 2020. Anteroposterior and lateral weightbearing X-ray were performed before and after the operation. The parameters evaluated include (1) the hallux valgus angle (HVA), (2) intermetatarsal angle (IMA), (3) distal metatarsal articular angle (DMAA) and (4) tibial sesamoid position (TSP). A visual analog scale (VAS) was used to evaluate the pain level before and at the last follow-up after the operation. American Orthopaedic Foot & Ankle Society (AOFAS) Forefoot Score were assessed before and at the last follow-up after the operation. Patient satisfaction assessment was also conducted at the time. Results: A total of 42 patients with 50 feet met our inclusion criteria. Average age at the time of surgery was 61 ± 9 years. Follow-up data were obtained in all 42 patients. The average follow-up time was 47.4 ± 20 months. All radiological parameteres including HVA, IMA, DMAA and TSP had statistically significant improvement (p < 0.001). The VAS score and AOFAS score was also statistically significant before operation and at the last follow-up after the operation (p < 0.001). There are 41 (82%) feet in patients were very satisfied or satisfied. Conclusion: Rotation scarf with Akin osteotomy is demonstrated to be safe, effective, and feasible for correcting severe hallux valgus. It can obtain good long-term correction with a low incidence of recurrence and metatarsalgia. Postoperative satisfaction and functional recovery of patients are significantly improved.
