Abstract:Objective To explore the curative effect of the first metatarsal base wedge osteotomy combined with modified Mcbride surgery for moderate and severe hallux valgus. Methods Eighty patients with hallux valgus(131 feet) treated in Jiangsu Province Hospital from January 2010 to August 2017.Among them,68 feet with moderate to severe hallux valgus,who were treated with the first metatarsal proximal base wedge osteotomy combined with modified Mcbride surgery.The curative effect of the operation was analyzed. Results During one year follow-up period after operation,the valgus angle,the angle between the first metatarsal and the second metatarsal,and distal metatarsal articular angle of the first metatarsal significantly decreased compared with those before operation (all P<0.01).The incidence of complications was 3.33%.The VAS pain score was statistically lower than that before operation (1.68 ± 0.12 vs 6.65±0.31,P<0.01),and American Orthopedic Foot and Ankle Society (AOFAS) score was significantly higher than that (89.54±2.36 vs 42.38±3.42,P<0.01) before operation. Conclusion For patients with moderate and severe hallux valgus,the first metatarsal base wedge osteotomy combined with modified Mcbride surgery can improve the symptoms of patients with fewer complications and effectively alleviate the pain and promote the rehabilitation of foot function.
