Abstract：Objective:To analyze the effect of Zu-waixi Formula Ⅱ(足外洗方Ⅱ号)on patients with hallux valgus complicated with metatarsalgia after surgery.Methods:A retrospective study method was adopted to collect 98 patients(140 feet)who under-went Wen's minimally invasive osteotomy and manual reduction combined with Weil osteotomy due to moderate to severe hallux valgus complicated with metatarsalgia.Among them,there were 12 male patients(17 feet)and 86 female patients(123 feet).According to whether the Zuwaixi Formula Ⅱ was used 6 weeks after the surgery,the included patients were divided into the treatment group(72 feet)and the control group(68 feet).The treatment group used the Zuwaixi Formula Ⅱ from 6 weeks to 12 weeks after the surgery,while the control group did not receive this treatment.The American Orthopaedic Foot and Ankle Society(AOFAS)ankle-hindfoot score,the degree of foot swelling,and the scar hyperplasia index of the patients in the two groups were compared.Results:The AOFAS ankle-hindfoot scores of the patients in the two groups at 2 weeks,6 weeks,and 12 weeks after surgery were all higher than those before surgery(P＜0.001),and the degree of foot swelling at 6 weeks after surgery was higher than that at 2 weeks after surgery(P＜0.05),and the degree of foot swelling at 12 weeks after surgery was lower than that at 2 weeks after surgery(P＜0.05)and 6 weeks after surgery(P＜0.001).In the treatment group,the scar hyperplasia index of the patients at 6 weeks after surgery was significantly higher than that at 2 weeks after surgery(P=0.020),and the scar hyperplasia index at 12 weeks after surgery was lower than that at 6 weeks after surgery(P＜0.001).In the control group,the scar hyperplasia index of the patients at 6 weeks after surgery was higher than that at 2 weeks after surgery(P＜0.05),and the scar hyperplasia index at 12 weeks after surgery was higher than that at 6 weeks after surgery(P＜0.001)and 2 weeks after surgery(P＜0.05).At 12 weeks after surgery,the AOFAS ankle-hindfoot scores of the patients in the treatment group were higher than those in the control group(P＜0.001),and the degree of foot swelling and the scar hyperplasia index were lower than those in the control group(P＜0.001).Conclusions:The Zuwaixi Formula Ⅱ has a better intervention effect on patients with hallux valgus complicated with metatarsalgia after surgery.It can promote the recovery of the affected foot's function and the reduction of swelling,and inhibit scar hyperplasia.
