Swelling and tenderness on the outside of the hip

Introduction Lateral hip swelling and tenderness are one of the clinical diagnostic criteria for intertrochanteric fractures. Intertrochanteric fractures occur mostly in the 66 to 76 years old. The incidence of women is three times higher than that of men. Griffin and Boyd's study of 300 cases of intertrochanteric fractures showed that the mortality rate of patients within 3 months after injury was 16.7%, which was about twice the mortality rate of patients with femoral neck fractures. The reason for such a high case fatality rate is that the patient is older; the fracture causing the fracture is heavier; the blood loss after the fracture is large; the treatment is relatively large. It can be seen that the intertrochanteric fracture is a more serious fracture.

Cause

(1) Causes of the disease

Direct violence reverses often causing intertrochanteric fractures of the femur.

(two) pathogenesis

Osteoporosis in the elderly, limb inflexibility, when the lower limbs suddenly twisted, fell or caused the large trochanter to directly contact the ground, it is easy to cause fractures. Due to the complex stress of the trochanter and the forward angulation, the hip varus deformity and the small trochanteric fulcrum as the fulcrum to form a small trochanteric butterfly fracture can also cause the small trochanter caused by the sudden contraction of the iliopsoas muscle. Avulsion fracture. The trochanter bone is crispy, so the fracture is often comminuted.

[Main diagnosis basis]

1. Pain in the hip after injury, can not stand and walk.

2. The lateral hip is swollen and tender.

3. The external rotation and shortening of the lower extremities are obvious, the activity is limited, and there is axial axillary pain.

4. X-ray inspection.

Differential diagnosis

Differential diagnosis of lateral swelling and tenderness of the hip:

1. Hip soreness discomfort: The soreness caused by acetabular dysplasia will initially be located in the knee joint, and then mainly 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.

Pediatric hip subluxation, also known as "children's hip joint staggered", "children's hip joint transient synovitis". The age of onset is more common in 5-10 years old, followed by 2-5 years old, followed by 10-15 years old, and occasionally adult (mostly female). The disease is a frequently-occurring disease in children, with more females than males, about 6:4. Most patients must be cured by manual reduction after the disease occurs. Otherwise, adverse consequences will result.

2, hip joint pain: folks commonly known as "squatting pain." In medicine, we call it "hip pain", referred to as "hip pain", which is an uncomfortable pain around the hip or joint. There are many causes of hip pain, and there are different reasons for different age groups.

3, hip pain: mainly manifested as hip pain, there is a sound when the hip posture changes, or the joint suddenly stuck. The hip strength of the affected side is reduced, and it is difficult to run fast or support one leg. Severe patients can't even lie on their side. Pain can make the legs unable to open the hips, and may also feel pain when walking. Adults are more likely to have chronic rheumatoid arthritis or degenerative hip joint disease. If this happens to children, it may be "Petz disease", one of the bone diseases.
