Hip soreness

Introduction The soreness caused by acetabular dysplasia is initially located in the knee joint, and is mainly located in the hip, thigh root, and groin area. The initial performance is the soreness of the hips. It will increase after standing for a long time or after a long walk. It will generally improve after the break. Most patients will think that they are tired or sprained and have not paid attention to it. Acetabular dysplasia, also known as hip subluxation, refers to a hip deformity that is not formed by the acetabulum. The main pathological change is that the acetabulum becomes shallow, resulting in insufficient tolerance and coverage of the acetabulum to the femoral head. Due to the above pathological changes, the weight-bearing area of the hip joint is reduced, and the pressure per unit area is significantly increased, which gradually causes the damage and degeneration of the articular cartilage, which eventually leads to the occurrence of hip osteoarthritis, painful hip joints and limited activity. Therefore, the variability of acetabular dysplasia is high.

Cause

The occurrence of this disease, mostly due to children jumping rubber bands, running, skating or slipping, resulting in excessive abduction or adduction of lower limbs and damage. Muscle spasm caused the joint position is not correct after injury, and the round ligament of the femoral head is squeezed or pulled, which makes the round ligament thinner and the blood supply is insufficient. The femoral head is necrotic due to ischemia.

1. There is no obvious history of trauma in children.

2, more than the beginning of the next day, hip pain, do not dare to bend the hip activities.

3. When walking, gait is dragged, or walking.

4, check: the child lying on the bed, take off the pants, the body is square, showing the length of the legs are not uniform, the groin becomes shallow, the middle part of the groin is tender. Hip pain occurs when the hip flexes 90 degrees, and the greater the degree of flexion, the more severe the pain.

5. The X-ray film shows normal.

Differential diagnosis

Differential diagnosis of hip soreness discomfort:

1. Dislocation of the medullary joint: There is a history of obvious trauma, local pain, swelling, dysfunction of the hip joint, and can not stand. X-ray film see the femoral head off the acetabulum.

2. Hip joint tuberculosis: Local pain symptoms are similar to this disease. However, hip tuberculosis has pain in walking and rest, and the night is obvious. The hips bend and the knees are not painful, but when they are straight, they feel pain, contrary to the disease. Later X-ray films showed that the acetabular or femoral head cartilage surface was rough and had a necrosis shape.

3. Suppurative hip arthritis: no history of trauma, acute onset, local redness, pain, and fever. There are systemic symptoms such as elevated body temperature and irritability, and the pain is obvious at night.
