Abstract

PURPOSE
The purpose of this study is to compare the treatment outcomes of distal chevron osteotomy with those of proximal metatarsal closing wedge osteotomy in patients with moderate severity hallux valgus.
MATERIALS AND METHODS
Forty-two patients (51 feet) who were underwent either distal chevron osteotomy (Group I, 22 patients, 27 feet) or proximal metatarsal closing wedge osteotomy (Group II, 20 patients, 24 feet) for the correction of moderate hallux valgus deformity were evaluated retrospectively. We assessed the radiographic results with several parameters including hallux valgus angle (HVA), intermetatarsal angle (IMA) and distal metatarsal articular angle (DMAA). And clinical results with modified AOFAS score at last follow-up.
RESULTS
There were no significant differences in IMA, HVA and DMAA between two groups preoperatively. We can achieve the good results with both procedures, but mean HVA and IMA of group II was significantly lower than those of group I. There was some loss of correction in group I at the last follow-up. There was no significant difference in clinical results according to modified AOFAS scoring between two groups at the last follow-up.
CONCLUSION
The proximal metatarsal closing wedge osteotomy for the hallux valgus with moderate severity is better treatment option to achieve better radiographic correction and to prevent loss of correction or recurrence than distal chevron osteotomy.
