【Abstract】 Objective To investigate the effect and advantage of oblique os teotomy of the first metatarsal in treatment of hallux valgus deformity. Method The measurement of hallux valgus angle(HVA), intermetatarsal an gle(IMA), and proximal articular set angle(PASA) were obtained from preoperative standing forefoot AP radiographs. All patients were treated with oblique osteot omy of the first metatarsal, 19 feet of which combined with the great toe proxim al phalangeal osteotomy and 6 feet with other metatarsal osteotomy.Resul ts The range of follow-up were from 6.2 to 44.0 months (average 19.6 m on ths ). All hallux valgus deformity were corrected. There was a significant diffe rence between preoperative and postoperative measurements of forefoot standing A P radiographs in HVA, IMA and PASA (P<0.01). The fineness rate was u p to 94.4%. One foot complicated with fracture of the first metatarsal.C onclusions Oblique osteotomy of the first metatarsal for treatment of hallux valg us is wider than other procedures in range of indications, which can be combined with other procedures and performed simply. Its strong fixation allows an early functional recovery. Oblique osteotomy of the first metatarsal is an effective and reliable procedure to correct the hallux valgus deformity, especially for se rious hallux valglus, with a minimum of complications.更多还原
