Outcome of opening-closing wedge osteotomy in the correction of Blount’s disease

Abstract

Background: Blount’s disease, a multiplanar deformity characterized by tibia vara, is usually a cause of concern for the caregivers. Although early onset Blount’s disease is treated with observation and trial of brace, surgical correction is usually needed for late or persisting deformities.
Objective: The aim of this study was to describe the technique and evaluate the outcome of openingclosing wedge osteotomy in the correction of Blount’s disease.
Design: This was a retrospective study.
Methods: Data was collected over a five year period (including age, follow up duration, pre and postoperative tibio femoral angles). Seventeen patients (with 25 extremities) were analyzed. SPSS version 22 was utilized.
Results: The majority of patients (41.2%) were aged between 5-10 years. The mean pre-tibio-femoral angle was 34.75 ± 16.51, while the post operativetibio-femoral angle was 7.83 ± 9.81. No implants were used.
Conclusion: Opening-closing wedge osteotomy is a safe and effective technique in the management of Blount’s disease
