title: The radiographic effects of the scarf bunionectomy on rearfoot alignment.
abstract: OBJECTIVE
  Excessive pronation of the rearfoot has been implicated as a destabilizing force in the progression of hallux abducto valgus. Although the scarf bunionectomy has been shown to effectively correct the intermetatarsal angle associated with hallux valgus deformity, its effect on the rearfoot has yet to be established. The purpose of this case series is to demonstrate the effect of the scarf bunionectomy on rearfoot alignment.
  
  
  METHODS
  Medical records were reviewed to isolate patients who underwent unilateral or bilateral scarf bunionectomies (with or without akin osteotomy) who had complete medical records, follow-up of at least 12 months, and met the inclusion/exclusion criteria. Preoperative and postoperative radiographic measurements were analyzed at various postoperative time intervals. Standard deviations and statistical significance was obtained.
  
  
  RESULTS
  One hundred feet (71 patients) were included in this analysis. The long-term results of this study highlighted the scarf osteotomy's ability to affect the medial longitudinal arch by decreasing the intermetatarsal angle and lateral talar-first metatarsal angle. The talar declination and calcaneal inclination angle were not significantly altered with the scarf bunionectomy.
  
  
  CONCLUSIONS
  This case series demonstrates that the scarf bunionectomy had significant effect on radiographic alignment of the bunion deformity and medial longitudinal arch over time. However, its effect on the rearfoot position was not statistically significant.
  
  
  METHODS
  Therapeutic, Level IV: Case Series.
