title: [The proximal crescentic osteotomy of the first metatarsal bone combined distal soft tissue reconstruction to treat severe hallux valgus].
abstract: OBJECTIVE
  To explore the method of the treatment for hallux valgus with the proximal crescentic osteotomy of the first metatarsal bone, combining with distal lateral soft tissue release.
  
  
  METHODS
  From January 2008 to December 2012, 21 cases 21 hallux valgus feet were treated by operative procedure, included 1 male (1 foot) and 20 females (20 feet), with the mean age of 52 years (range, 36-68 years). Among all patients were followed up for 12 to 26 months, with the mean 16 months. The preoperative, post-operative and final follow-up X-ray films of all patients were collected. The hallux valgus angle, intermetatarsal angle and distal metatarsal articular angle were measured and analyzed. The surgical outcome was evaluated combined with the AOFAS score.
  
  
  RESULTS
  The average hallux valgus angle decreased from 42.3° ± 1.8° preoperatively to 14.5° ± 1.8 postoperatively, the average intermetatarsal angle did from 21.9° ± 1.7 to 9.1° ± 1.8°, and the average distal metatarsal articular angle did from 14.9° ± 1.8 to 7.2° ± 1.5, respectively. There were significant differences between the preoperative and postoperative roentgenographic index. AOFAS score was improved from 44.0 ± 1.8 preoperatively to 83.9 ± 2.2 at the final follow-up.
  
  
  CONCLUSIONS
  The proximal crescentic osteotomy of the first metatarsal bone combined distal soft tissue reconstruction obtained satisfactory results in severe hallux valgus patients with big intermetatarsal angle.
