title: Correction of cubitus varus by French or dome osteotomy: a comparative study.
abstract: BACKGROUND
  The purpose of this study was to compare the outcomes of two different techniques of supracondylar osteotomy, French osteotomy and dome osteotomy, for the correction of posttraumatic cubitus varus.
  
  
  METHODS
  A comparative randomized study was undertaken of 25 patients (average age 10 years) with an established posttraumatic cubitus varus deformity (mean time from injury to corrective osteotomy, 1.7 years). Patients were followed-up with for 1 year, and carrying angle, Baumann's angle, and internal rotation deformity were measured. Postoperative complications were assessed.
  
  
  RESULTS
  A significant (p < 0.01) correction of carrying angle and Baumann's angle was achieved with both techniques, with no statistically significant differences between them. Although internal rotation deformity was corrected by both techniques, the correction was significantly greater with the dome osteotomy (p < 0.01). However, the persistence of internal rotation did not seem to affect the final outcome. There was a higher incidence of postoperative complications in the dome osteotomy group, including infection (1), inadequate correction (1), nerve palsy (1), loss of motion (5), and circulatory compromise (1).
  
  
  CONCLUSIONS
  The dome osteotomy is technically more difficult than the French osteotomy and has a higher incidence of complications. We suggest that the French osteotomy be used for the correction of cubitus varus after supracondylar fractures of the elbow in children.
