Residual Torsional Deformity in Pediatric Genu Varum After Coronal Plane Deformity Correction by 8 Plate Hemi Epiphysiodesis.

Angular deformities around the knee in children is a common finding including genu valgum and genu varum.

The genu valgum or varum may be idiopathic or arise from diverse etiologies, such as trauma, dysplasia, metabolic disease, inflammatory, endocrine, tumor, neoplastic, or developmental pathologies.

Surgical treatment options include osteotomies with either acute or gradual correction and temporary hemi epiphysiodesis (guided growth),the latter being less invasive and with significantly lower rate of major complications.

Guided growth by 8 plate hemi epiphysiodesis is commonly used to correct coronal plane deformity around the knee. Since its introduction by Stevens in 2007 many studies have demonstrated the efficacy, safety and advantages of tension band plating in the paediatric age group as an alternative to corrective osteotomy.

Genu varum deformities of the leg are often associated with internal tibial torsion. The 3 major causes of pediatric in-toeing are metatarsus adductus, internal tibial torsion, and femoral anteversion.
