The Cincinnati Children's Hospital Medical Center Hip Deformity Service treats patients with coxa vara. Coxa vara is an unusual hip condition in which there is a discrepancy of growth in the round ball part of the joint and the upper end of the thigh bone. This discrepancy leads to overgrowth, and a shepherd's crook deformity of the hip joint.
Coxa vara usually presents with a limp, and limited ability to bring the thigh out to the side. X-rays are diagnostic. Depending on the underlying cause and severity of the deformity, reconstructive surgery may be needed to improve the hip alignment and biomechanics.
