Abstract

• We evaluated the clinical results of the closed reduction and percutaneous K-wire fixation for supracondylar fracture of the humerus in thirty patients who were treated from Jan 1990 to Nov 1993. We analyzed the relationships between non-anatomical reduction and occurrence of varus deformity in displaced supracondylar fractures of the humerus in children.
  The following results were obtained:
  1. There were twenty-two males and eight females, twelve cases of type IIB and eighteen cases of type IIIfractures by Gartland classification. Posteromedial displacement and fractures through the olecranon fossa were most common pattern.
  2. After closed reduction, eleven rotations and three medial displacements of distal fragment, and three angular deformities of medial cortex were observed in eleven cases.
  3. Radiologically, the differences of carrying angle compared with normal side were decreased in twenty-one cases, no changes in three cases, and increased in six cases.
  4. Two cubitus varus deformities were developed in decreased cases more than six degrees of carrying angle with residual rotation and medial displacement.
  5. We obtained relatively good results in supracondylar fracture of the humerus in children treated by closed reduction and percutaneous K-wire fixation with grossly normal carrying angle.
