- Abstract
Objectives: To clarify the effect of combining medial capsule interposition with modified scarf osteot- omy for hallux valgus. Methods: A multicenter, retrospective study included 64 cases [59 osteoarthritis patients (excluding rheumatoid arthritis); age 68.8 years, range 40-93 years] of modified scarf osteotomy which were performed from 2013 to 2017 and followed for 26.6 (range, 13-50) months. Patients were treated by either (1) without medial capsule interposition (33 cases) or (2) combined with interposition (31 cases) at each senior surgeon-s discretion. The Japanese Society for Surgery of the Foot (JSSF) hallux metatar-sophalangeal (MTP)-interphalangeal scale was evaluated along with radiographic parameters (hallux valgus angle [HVA], first and second metatarsals intermetatarsal angles, and Hardy grade). Results: All JSSF scale and radiographic parameters were similar at baseline and significantly improved at final follow-up in both groups (pre-operation vs. final follow-up: p<.001). However, compared to without interposition group, interposition group showed significantly higher improvement in the JSSF scale (pre-operation to final follow-up: p value between the two groups at final follow-up) for pain (without interposition: 19.4-34.2, interposition: 18.4-37.1; p=.02), function (without interposition: 20.8-33.6, interposition: 18.3-36.6; p=.005), total score (without interposition: 41.5-81.8, interposition: 38.5-88.5; p<.001), and the MTP joint space (without interposition: 1.4-1.5mm, interposition: 1.6-2.6mm; p<.001) with significant correlation between the total JSSF score (r=.40; p=.001). Conclusion: Combining medial capsule interposition with modified scarf osteotomy significantly improved mid-term clinical outcomes.
