Explore the influence of hip replacement on lower extremity hemodynamics in Crowe Ⅳ hip dysplasia patient.
Changes of limb length after total hip replacement is common, especially for Crowe Ⅳ hip dysplasia patient. Such change potentially increases tension of vessel and influence lower extremity hemodynamics. Till now, little is known in this area.
