What are the symptoms of necrosis of the femoral head?

There are many clinical symptoms of femoral head necrosis, among which the more common ones are: 1. Pain The pain of femoral head necrosis is not limited to the femoral head, but around the hip joint, inner thigh, front or knee. There are also quite a few types of pain:

Dull, dull, stabbing, intermittent pain. The pain is worse after too much activity, and it can be slightly relieved with rest, and some patients have persistent pain. The pain symptoms of late femoral head necrosis become more severe after activity, reaching the point where the pain is immediate when it moves, and the pain stops when it is still.

2. Claudication The main causes of claudication are pain, limited hip function, and secondarily shortening of the affected limb. Painful claudication is characterized by the fact that the affected limb does not dare to step on the ground with weight, and the foot on the affected side is lifted immediately as soon as it steps on the ground, that is, the healthy foot lands heavily and for a long time, and the affected foot lands lightly and for a short time, and the function is limited. In addition to pain and shortening of the affected limb, the main manifestation of claudication is adduction of the affected hip, that is, the knee joint of the affected side is tightly moved closer to the unaffected side, and even the knees rub against each other.

3. Hip joint dysfunction The main manifestations of hip joint dysfunction are: abduction, adduction, difficulty in bending and extending forward, difficulty in squatting, dare not cross legs, joint stiffness, and inflexibility in leg lifting. The clinical symptoms of femoral head necrosis are introduced to you, and we need to actively carry out and prevent femoral head necrosis.

Common early symptoms of femoral head necrosis in children, situations that need parental attention: 1: Claudication 2:

"Duck step" may occur in children with necrosis of the femoral head in both sides"Duck step", that is, when walking, the sides of the pelvis rise and fall alternately, and the torso also swings from side to side at the same time, like a "duck" walking. In adulthood, secondary hip osteoarthritis occurs, and the hip pain and stiffness make it impossible to walk normally, resulting in disability.

Three: Limitation of joint mobility.

Early symptoms include: low back pain, hip pain on the affected side, groin pain on the affected side, knee pain in the affected limb, chills in the affected limb, weakness when moving a lot, soreness, and fatigue. Interim symptoms:

Medium-stage femoral head necrosis, the symptoms are very obvious, mainly claudication, walking pain, dysfunction, when taking X-ray, you will see most of the trabeculae disappearing, cystic changes, osteosclerosis, and fracture and collapse of the cartilage of the femoral head. In the late stage of femoral head necrosis, the patient has more severe claudication, obvious feeling of short legs, difficulty in walking, pain, x-ray will see flattening and collapse of the femoral head, narrowing or disappearance of the joint space, obvious cystic changes, large area of osteosclerosis, complete fracture of the cartilage of the femoral head, and rough articular surface.

The main symptoms of femoral head necrosis are:

1. Pain: It mostly occurs in the first part of the femoral head, that is, the groin part, the pain is sometimes localized to the groin part, and also occurs around the knee joint and hip joint, and some patients have pain radiating along the inner thigh to the knee joint, and may ignore the necrosis of the femoral head due to **knee joint pain, resulting in misdiagnosis and delay. Clinical analysis and accurate examination must be carried out to determine whether the pain is caused by necrosis of the femoral head;

2. Claudication: that is, stilted or lame, some patients collapse the femoral head or severe swelling of the joints around the femoral head due to necrosis of the femoral head, and at this time, the length of the legs is different;

3. Difficulty walking: Some young adults have a complete decline in labor force and working ability due to necrosis of the femoral head, resulting in difficulties in life;

4. Muscle atrophy: necrosis of the femoral head leads to pain in joint functional activity, triggers the body's self-protection effect, produces muscle disuse atrophy, and causes different thicknesses of the legs.

The above symptoms may affect each other, and patients should not be masked or bothered by lumbar spine disease or other knee joint diseases, and should go to the hospital for examination to diagnose whether femoral head necrosis has occurred.

Necrosis of the femoral head.

Early manifestations are atypical, predominantly in the hip or groin area.

Pain or soreness, relieved by rest, as the disease progresses, the femoral head collapses, at which point the pain worsens, the limb shortens, and gradually difficulty walking or claudib.

What are the early symptoms of femoral head necrosis?

Patients with necrosis of the femoral head have atypical early symptoms, and pain is the earliest complaint in most patients, mainly presenting with pain or soreness in the hip or groin area. The pain is intermittent and gradually worsens and is relieved with rest.

What are the typical symptoms of femoral head necrosis?

The typical symptom of necrosis of the femoral head is pain in the groin area, which can radiate to the ipsilateral hip or knee.

Pain is often intermittent and progressively worsening, with occasional acute episodes.

If the lesion involves both hip joints.

May present with alternating pain on the left and right sides. There are also a small number of patients who have no clinical symptoms in the early stage and gradually develop difficulty walking, limited hip movement, stiffness, or painful claudication. If the femoral head collapses, it may be accompanied by shortening of the lower limbs, compensatory tilting of the pelvis, and forced walking on crutches.

Signs. Patients often have deep tenderness in the groin area, hip pain during strong internal rotation, positive "4" test, and significant limitations in internal rotation and abduction of the lower limbs.

The most important signs of femoral head necrosis are pain, joint stiffness, limited mobility, and claudication.
