ABSTRACT
[Objective]To evaluate the effect of transverse arch reconstruction by modified Youngswick osteotomy on young and middle-aged hallux valgus. [Methods]From November 2005 to November 2008,25 female(36 feet) hallux valgus patients with the average age of 37.7years old(range 22 to 49 years old) were treated surgically.All feet had hypemobility of the first tarsometatarsal joint and collapse of the transverse arch of the foot.In the operation,the first metatarsal head was pushed laterally,downward and rotated downward.Modified McBride procedure was used on the correction for hallux valgus deformity.The X-ray films of all patients were obtained before operation,and 12 months after operation.The hallus valgus angle and intertatarsal angle were measured and analyzed on radiographs.The surgical outcome was evaluated combined with the Gu Xiang-jie's score.All pamameters were statistically analyzed.All cases were followed-up regularly.[Results]Twenty-one cases(28 feet) were followed-up for averaged 15.9 month.Hallax valgus angle reduced from 26.8??1.07? to 11.1??0.29?,intertatarsal angle reduced from 14.9??1.36? preoperatively to 8.3??1.19? postoperatively.The painful callus beneath the forefoot was alleviated or diminished obviously in all cases.Based on Gu Xiangjie'score,the subjective assessments were given as excellent in 16 feet,good in 7 feet,and fair in 5 feet.The good to excellent result was 82.1%.[Conclusion]For the hallux valgus with hypermobility of the first tarsometatarsal joint and transversal arch collapse,modified Youngswick surgery can recover the transverse arch,correct first metatarsal adduct abnormality,and regain the weight-bearing function of the first metatarsal head.Modified Youngswick surgery is an ideal choice for young and middle-aged hallux valgus because of less complications and reliable surgery outcomes.
ABSTRACT
[Objective]To evaluate the effects of Austin surgery for mild and moderate juvenile hallux valgus. [Method]From November 2005 to Januuary 2007,16 juvenile hallux valgus patients(28 feet)with average of 17.8 years(range,17 to 19 years)were treated with Austin surgery.The X-ray films of all patients were obtained before operation,and twelve months,fifteen months after operation.The hallus valgus angle,intermetatarsal angle,proximal articular set angle,and distal articular set angle were measured and analyzed on radiographs.The surgical outcome was evaluated combined with the Gu Xiang-jie's score.All pamameters were statistically analyzed. [Result]All the patients were completely followed up.Hallax valgus angle reduced from 26.3?1.19 to 11.7?0.40,intermetatarsal angle reduced from 14.1?0.82 to 7.2?0.85,proximal articular set angle from 12.7?0.28 to 6.4?0.54(all P
