title: Range of motion of the first metatarsophalangeal joint after chevron procedure reinforced by a modified capsuloperiosteal flap.
abstract: BACKGROUND
  This study analyzed the range of motion of the first metatarsophalangeal joint following the chevron procedure with increased stabilization using a modified capsuloperiosteal flap in the treatment of hallux valgus cases.
  
  
  METHODS
  Forty-three feet of 40 patients were treated with modified chevron osteotomies. The patient selection criteria included failure of conservative treatment, painful deformity, age between 18 and 50, hallux valgus and intermetatarsal angles less than 40 degrees and 17 degrees, respectively, and no osteoarthritic changes of the metatarsophalangeal joint. The passive range of motion of the first metatarsophalangeal joint was compared to the hallux valgus and intermetatarsal angles.
  
  
  RESULTS
  The mean age of patients was 30.9 +/- 9.0 (range, 18 to 46) years. The preoperative mean hallux valgus angle was 32.2 (range, 22 to 40 degrees), whereas postoperatively it was 13.1 (range, 3 to 22 degrees). The preoperative mean passive total range of motion, dorsiflexion and plantar flexion were found to be 80.2 (range, 71 to 99 degrees), 66.8 (51 to 86) degrees and 13.4 (range, 7 to 23 degrees), respectively, whereas postoperatively these values were 69.2 (range, 48 to 85 degrees), 58.6 (range, 43 to 75) degrees and 10.8 (range, 1 to 20 degrees). According to Bonney and MacNab subjective scores, the feet were evaluated as follows: 12 as excellent, 26 as good, and 5 as moderate. According to objective scores, the evaluation was as follows: 27 as excellent, 14 as good, 1 as moderate, and 1 as poor.
  
  
  CONCLUSIONS
  We believe that the chevron procedure reinforced by modified capsuloperiosteal flap causes minimal irritation and damage to adjacent soft tissues. Furthermore, we conclude that this method is a benefical means of managing moderate hallux vagus deformities by decreasing the stiffness after surgery.
