Abstract
|
|
|
Purpose: To analyze the relationship between cubitus varus deformities and rotatory abnormalities after bone union.
Materials and Methods: A total of 263 patients were diagnosed with Gartland type II supracondylar humerus fractures between May 1996 and May 2003 and underwent surgery. The Gartland method was used to classify the fractures. Of the 263 cases, 141 were type II, and 122 were type III. All patients underwent subcutaneous K-wire fixation after manual reduction except one that showed open radial nerve damage at the time of trauma. A mathematical method was used to evaluate rotation abnormalities in the axial plane.
Results: There was no postoperative nonunion or iatrogenic ulnar nerve palsy in 8 cases of cubitus varus deformity. Cubitus varus deformities failed to show a statistically significant correlation with malrotation in the axial plane.
Conclusion: There was no relationship between rotatory abnormalities after union and cubitus varus deformities.
