2. Joint stiffness and limited mobility. Poor hip flexion and extension, difficulty squatting, inability to stand for a long time, and duck-like walking. Early symptoms are limited abduction and external rotation.

3. Lameness. Progressive shortening claudication is caused by hip pain, femoral head collapse or late-stage hip subluxation. Intermittent claudication often occurs in the early stages, and is more obvious in children.

4. Physical signs. Local deep tenderness, tenderness at the adductor muscle insertion, positive 4-digit test, positive G-sign, positive A11is sign, positive TKDele-Uq test. Limited abduction, external rotation or internal rotation, shortening of the affected limb, muscle atrophy, and even subluxation. Sometimes positive axial thrust pain.

Femoral head necrosis, also known as aseptic necrosis of the femoral head and ischemic necrosis of the femoral head, has the following symptoms: Early symptoms include: low back pain, side hip pain, side groin pain, knee pain, limb coldness, weakness in movement, pain, and fatigue. In the middle stage of femoral head necrosis, the symptoms are very obvious, mainly including lameness, walking pain, functional impairment, and taking X-films, you will see that most of the trabeculae disappear, cystic changes, bone sclerosis, femoral cartilage fractures and collapses. In the late stage of femoral head necrosis, patients have more severe lameness, obviously feel short legs, have difficulty walking, and pain. X-rays will show that the femoral head is flat and collapsed, the joint space is narrow or disappeared, the cystic changes are obvious, the area of ​​bone sclerosis is large, the femoral head cartilage is completely broken, and the joint surface is rough.
