改良Ludloff截骨术治疗重度拇外翻疗效观察

Objective To explore the midterm effect of modified Ludloff osteotomy for the treatment of severe hallux valgus deformity associated with metatarsus primus varus. Methods Totally 25 patients(30 feet) with severe hallux valgus deformity were treated by modified Ludloff osteotomy and distal soft tissue procedure from March 2006 to 2008 March. Four feet were treated furtherly with reverdin osteotomy. Three feet were treated furtherly with Akin osteotomy. All the patients underwent weight bearing radiograph examination. The follow-ups ranged from 24 to 35 months ( average 28.3 months). The effect was evaluated by Maryland clinical rating systems of AOFAS.Results All the patients underwent the follow-up. There was no bone nonunion, malunion and wound infection,but one old patient had delayed union. According to Maryland clinical rating systems of AOFAS, 19 feet(63.3%)were excellent ( 90 to 100 scores), 8 feet ( 26.7 % ) were good ( 80 to 89 scores), 3 feet ( 10. 0% ) were middle (70 to 79 scores). Conclusions Modified Ludloff osteotomy has the advantage of rapid healing, less shortened metatarsal and ability to correct deformity, which can relieve the pain and recover the function of forfoot. It is a perfect procedure for severe hallux valgus deformity patients whose intermetatarsal angle is over 16°.
