| Abstract | ||
| Background Cubitus varus is a complex multiplan deformity of the elbow where the extended forearm is deviated towards the midline of the body. It is commonly found as a complication following neglected or improperly reduced supracondylar humeral fracture in children. Different osteotomy techniques were described for the correction of this deformity. Dome and modified step-cut osteotomies are among the commonly used techniques. In this study, the authors aimed to compare the clinical and radiological results of both types of osteotomies. Patients and Methods A total of 39 children with cubitus varus deformities following supracondylar humeral fracture were managed either by a dome (group I) or modified step-cut (group II) osteotomy. Correction was performed within a mean of 3 years (1.5–5 years) from the incident of fracture. Patients were assessed in terms of the carrying angle, elbow range of motion, and lateral prominence index. Preoperative planning was done for every case, and osteotomies were fixed by K-wires in dome osteotomies and by K-wires or screws in modified step-cut osteotomies. Results Fifteen patients had excellent results, and five patients had good results in group I, while in group II, 14 patients had excellent results, and five patients had good results. The carrying angle, elbow range of motion, and lateral prominence index were significantly improved in both groups. No significant complications were encountered in any of these patients throughout the study. Conclusions Both dome and modified step-cut osteotomies are reliable techniques for correcting cubitus varus in children. Both were comparable in achieving deformity correction and minimizing the lateral condylar prominence. However, dome osteotomy has been found to be technically easier. | ||
