ABSTRACT
Objective To explore the surgical skill and curative effect of Scarf combined with modified Mcbride osteotomy for treating moderate to severe hallux valgus.Methods Thirty-eight patients (47 feet) with moderate to severe hallux valgus in the Southwest Hospital of Army Military Medical University from July 2014 to June 2015 were selected and treated by Scarf combined with modified Mcbride osteotomy,among them,31 cases(38 feet) were followed up.The cases of phalanx proximal articular angle(PAA) enlargement were added with Akin osteotomy hallex proximal phalanx,and 2,3 plantar Weil osteotomy was used in the patients with 2,3 plantar bone metastasis pain.The hallux valgus angle (HVA),1,2 intermetatarsal angle (IMA),distal metatarsal joint fixed angle(DMAA),PAA were compared between before and after surgery by the erect position,anteroposterior position and lateral X-ray films.The therapeutic effects were assessed by adopting the American Orthopedic Foot and Ankle Society(AOFAS) scoring system.Results The follow-up time was 12～18 months(average 16.42 months).HVA was decreased from preoperative(41.82±5.28)° to postoperative(17.03±4.04)°,IMA was decreased from preoperative(19.00 ± 3.78)°to postoperative(9.24 ± 1.98)°,DMAA was decreased from preoperative(19.42±5.65)°to postoperative(8.71±2.74)°,PAA was decreased from preoperative (5.66± 3.27) ° to postoperative (3.82 ± 2.09) °,and AOFAS score was increased from preoperative (41.47 ± 6.29) to postoperative (84.82 ± 6.43),the differences were statistically significant (P＜0.05).Conclusion Scarf combined with modified Mcbride osteotomy has satisfactory effect for treating moderate to severe hallux valgus.
