​Pain in the joint where the thigh meets the hip bone

Pain in the joint where the thigh meets the hip bone is also called hip pain. Hip pain is a very common phenomenon. If such a situation occurs, you need to compare your own situation and analyze the reasons for it. For example, for people who exercise regularly, joint pain at the thigh joint and hip bone is likely caused by muscle and tendon strain during daily exercise. Other causes are detailed below.

In fact, what people commonly call "hip pain" or "thigh pain" is medically called "hip joint pain", which manifests as pain and discomfort in the hip joint or around the joint. However, please note that hip pain does not necessarily mean femoral head necrosis!

What causes hip pain?

There are many causes of hip pain, the following are the most common:

1. Muscle and tendon strain: usually caused by a history of acute trauma or strenuous exercise. Local exudation leads to swelling, tenderness, and ecchymosis. The diagnosis can be confirmed by B-ultrasound or MRI.

2. Hip osteoarthritis: common in middle-aged and elderly people, caused by degenerative changes in hyaline cartilage, chondromalacia, etc., often affecting both sides. The clinical manifestations are joint pain and inflexibility. The main causes are aging, long-term unreasonable posture and exercise, trauma and drugs.

3. Developmental dysplasia of the hip: This disease is a congenital developmental disease and is common in women. It often affects both sides.

4. Ankylosing spondylitis involving the hip joint: common in adolescent males, mostly involving bilateral sacroiliac joints, and HLA-B27 is mostly positive.

5. Rheumatoid arthritis: more common in middle-aged and elderly women, affecting both sides.

6. Temporary osteoporosis: It can be seen in young and middle-aged people, often occurring on one side, with temporary pain in the hip joint without obvious cause.

7. Lumbar disc herniation: It is more common in people who engage in long-term heavy physical activities. Lumbar disc herniation compresses the spinal nerve roots, causing pain in the waist, buttocks, hip joints and other parts.

8. Avascular necrosis of the femoral head: Any factor that affects the local blood supply to the femoral head, such as femoral neck fracture, long-term use of glucocorticoids, alcoholism, etc., causes bone cell death, which in turn leads to structural changes in the femoral head, causing femoral head collapse and dysfunction. This disease is called avascular necrosis of the femoral head. The main symptoms are hip pain mainly in the groin, buttocks and thigh areas, and limited internal rotation of the hip joint.

9. Bone or soft tissue tumors.
