Bilateral developmental coxa vara

Coxa vara in children is either a consequence of a congenital malformation or a developmental anomaly and is defined as a decrease in the femoral neck-shaft angle below a normal of 120°. The chief clinical features are limb shortening/deformity, limping, and delay or difficulty in walking. In cases of bilateral involvement, a distinctive waddle and exaggerated lumbar lordosis is noted. Prompt and early management leads to good results, whereas untreated cases often advance to crippling disabilities. This case report describes a 6-year-old boy presenting with walking difficulty, having the characteristic clinicoradiological features of bilateral developmental coxa vara.
