Cubitus varus deformity of humerus correction with modified lateral closed wedge Osteotomy.
Pak J Surg Jan ;25(1):58-61.

Objective: To evaluate the outcome of modified lateral closed wedge osteotomy for cubitus varus deformity. Study Design: Quasi-experimental study. Setting & Duration: Orthopaedic Department of Ayub Medical College and Teaching Hospital Complex, Abbotabbad and Khyber Teaching Hospital Peshawar from January 2006 to June 2008. Methodology: Thirty patients with cubitus varus deformity secondary to malunited supracondylar fracture of the humerus between the ages of seven to fourteen years. Clinical and radiological assessment of the upper extremity was done in all the cases. Modified lateral closing wedge osteotomy with two screws and tension bend wire between them and 2-K wires from the lateral side to engage the medial cortex of the proximal fragment were done to correct the deformities. All the patients were followed for six months. Postoperatively the patients were examined for range of motion (ROM, scar and postoperative complications. Carrying angle and lateral condylar prominence index were calculated on antero posterior and lateral radiograph of the elbow. Results: Thirty patients with twenty two males and eight females were studied. The average age at the time of osteotomy was 8.5yrs (range 7-12 years). The average preoperative carrying angle was 25.2 degree varus (range 18-30) and the postoperative angle was 7 degree valgus (6-13). There were no significant difference between the pre and postop range of motion. The average preoperative lateral condylar prominence index (LCPI) was 175 degrees (range 128-232) and postoperative LCPI was 156 degrees (range 100-240). Twenty six patients were excellent, two good and two poor results. Conclusion: The additional fixation by K-wires controls rotational forces effectively besides angulation and translational forces and maintain the correction achieved.
