Does congenital coxa vara represent a variant of slipped capital femoral epiphysis with chronic changes?

A few studies in the literature do consider CCV a variant of a chronic slip with the continued varus biomechanically predisposing to increased shear stresses across the proximal femoral physis. The changes found in the cartilage of this physis are suggested to resemble those found in SCFE. Other studies suggest that imaging (eg, MRI) results are not similar to those of SCFE and that a chronic slip theory does not explain the bone changes found in the metaphyseal bone of the proximal femur. The authors believe that a more generalized bone abnormality is present that predisposes these patients to deformity. Hopefully, future investigations will shed further light on this topic. When is the best patient age at which to operate on hips affected by this condition? Most patients seem to present for evaluation and are considered for treatment when aged 5-10 years. Femoral osteotomy procedures are technically easier in the older child, as more bone stock is present. Earlier surgical interventi
