title: The effect of sesamoid position on outcome following scarf osteotomy for hallux abducto valgus.
abstract: BACKGROUND
  Hallux valgus is a common forefoot condition, with numerous operations described to correct the deformity. Debate remains as to the relative importance of correcting the position of the sesamoid apparatus.
  
  
  METHODS
  Forty-six cases were reviewed. Preoperative and post-operative X-rays were used to measure forefoot width, inter-metatarsal angle (IM), hallux valgus (HV) angle and sesamoid position (Reynolds stations). Satisfaction was assessed via questionnaire.
  
  
  RESULTS
  Significant improvements were seen in all radiological parameters. 37/43 patients were satisfied with the result. Comparison between the satisfied and non-satisfied group revealed significant differences in the IM angle (p<0.05) and HV angle (p<0.05). However, patient satisfaction was not associated with post-op sesamoid position or change in sesamoid position (p>0.05).
  
  
  CONCLUSIONS
  This study showed that scarf osteotomy, can successfully correct hallux valgus, with high levels of satisfaction. Satisfaction is associated with a greater correction of deformity. Improvement in sesamoid position was not associated with patient satisfaction.
