title: Correction of severe hallux valgus using a basal chevron osteotomy and distal soft tissue release.
abstract: BACKGROUND
  There are many procedures described for the correction of severe hallux valgus. This is the first to examine the role of a basal osteotomy with distal soft tissue release.
  
  
  METHODS
  26 patients with severe hallux valgus underwent a basal chevron osteotomy with distal soft tissue release. All were reviewed at an average of 38 months.
  
  
  RESULTS
  The mean AOFAS score improved from 24 to 82 points (p<0.001). The IMA improved from an average of 23.90 to 130 (p<0.01). The HVA improved from an average of 490 to 170 (p<0.005). The correlation coefficient between the AOFAS score and various radiological angles was low (0.47).
  
  
  CONCLUSIONS
  Good clinical outcomes in cases of severe hallux valgus can be achieved without full restoration of normal radiological values. Furthermore, a basal chevron osteotomy with a distal soft tissue release offers a high satisfaction rating with regards to both clinical and functional outcomes in the short to medium-term.
  
  
  METHODS
  Level IV - Case series.
