Abstract
Objective: This study Outlines the technique and evaluates the functional outcome of modified step cut 3 D
osteotomy for pediatric post traumatic cubitus varus deformity avoiding drawbacks of biplanner osteotomy
like residual deformity, lateral prominence, loss of fixation and ulnar nerve palsies.
Patients and methods: 24 cases (18 boys and 6 girls) suffered from post traumatic cubitus varus deformity
due to mal-united supracondylar fracture humerus. Age ranged from 3 to 13 years old (mean 5 years old).
Mean management time was 3.3 years (1.5–6 years) after the injury using a modified step-cut 3 D osteotomy.
The average follow-up period was 2 years (1–3.5 years). Objective assessment included measurement of
preoperative and postoperative lateral prominence index, carrying angle and range of elbow motion. Results
were graded excellent, good or poor according to the Oppenheim criteria.
Results: There were 18 excellent, 5 good and 1 poor result. A residual varus of 5° was seen in the single patient
with poor result. None of the patients showed a prominent lateral humeral condyle or formation of hypertrophic scar.
Conclusion: A modified step-cut 3 D osteotomy is a safe and simple osteotomy which prevents lateral
prominence and provides excellent outcomes in most of the patients. The modified step-cut osteotomy
procedure, was superior to the conventional lateral closing wedge osteotomy regarding the lateral humeral
condyle prominence, less scaring and better cosmoses.
