title: Hallux valgus in men. Part II: First ray mobility after bunionectomy and factors associated with hallux valgus deformity.
abstract: OBJECTIVE
  To determine the 1st ray mobility following a distal soft-tissue procedure with proximal osteotomy (DSTP-PMO) and any associated factors.
  
  
  METHODS
  A retrospective study of 30 men (35 feet) was performed. First ray mobility, ankle dorsiflexion, pes planus, and metatarsus adductus were evaluated at the final follow-up. All internal fixation was routinely removed at six to eight weeks postoperatively. Standard radiographs were evaluated and angular measurements were calculated on all feet.
  
  
  RESULTS
  The mean follow-up was 78 months. No cases of degenerative arthritis of the 1st MTC joint were noted on follow-up radiographs. DSTP-PMO resulted in a mean postoperative 1st ray mobility of 4.9 mm (range, 2.5 to 8). In those feet evaluated following bunion correction, there was no correlation with pes planus, limited ankle dorsiflexion or metatarsus adductus. The preoperative hallux valgus angle and 1-2 intermetatarsal angle correlated with toe pronation and a positive family history. Twenty-two patients had an AOFAS score of 90-100, seven of 80-89 and one less than 69.
  
  
  CONCLUSIONS
  Hallux valgus in this group of male patients was not associated with limited ankle dorsiflexion or pes planus. Men with toe pronation and a positive family history had a greater hallux valgus deformity than those without after a distal soft tissue repair with proximal first metatarsal osteotomy. There was no evidence of first ray hypermobility after a DSTP-PMO.
