Synopsis

Tibia vara is an idiopathic tibial growth disorder in infants, children, and adolescents characterized by progressive bowing of the legs. Contributing factors include obesity and early walking, which are believed to disrupt normal ossification and chondrocyte processes. There are higher rates of occurrence in children of African descent. The infantile form is more common in females while the late-onset form is more common in males. More than half of cases are bilateral.

Characterized by below-the-knee bowing, leg length discrepancy of lower limbs, and in severe cases, knee, ankle, and lower leg pain. If left untreated, patient is at greater risk for development of severe deformity and early degenerative arthritis of the knee.

Staging is done by the Langenskiöld 6-stage classification system. Mild, early-onset cases may respond to braces and orthotic management. More severe cases require surgical correction.
