title: Surgical treatment of hallux valgus and forefoot deformities in Sweden: a population-based study.
abstract: BACKGROUND
  Although surgical correction for hallux valgus and other toe deformities is one of the most common procedures in foot surgery, its incidence in the general population is not well-known.
  
  
  METHODS
  The study population comprised patients living in Sweden of a varied age group and both sexes who underwent forefoot surgery. We identified all inpatient cases from 1997 to 2000 and all ambulatory cases in 2000 registered in the National Swedish Patient Register (NSPR). Further, clinical data for the surgical treatment of hallux valgus deformity were extracted from medical records in patients treated in a geographically defined region (Stockholm).
  
  
  RESULTS
  In total, 6956 patients with surgically treated forefoot deformities were identified from the adult population, equivalent to a cumulative incidence of 0.8 procedures per 1000 inhabitants for the whole analyzed group. There were regional variations and significant sex differences. The age distribution in both sexes was characterized by a peak in the fifth decade. Forefoot surgery was statistically more frequently performed in private clinics than in public hospitals (p < 0.001). Hallux valgus surgery was by far the most common procedure regarding forefoot surgery.
  
  
  CONCLUSIONS
  The prevalence of forefoot- and hallux valgus surgery was not evenly distributed in the six major regions in Sweden. It is more common in urban than in rural regions. Furthermore, forefoot surgery is performed more frequently in private clinics than in community hospitals despite common financial sources.
