Question

A child, now 1 year old, has hip dysplasia and cannot live a normal life.

Answer

Clinical observation of the following abnormalities can be noticed by parents or caregivers, indicating a unilateral complete dislocation or subluxation:

  1. Both legs are of uneven length, and the affected side has reduced mobility.
  2. One side (the affected limb) of the hip joint is less easy to abduct.
  3. The skin creases on both sides of the inner thigh, inguinal area, perineum, or buttocks are asymmetrical.
  4. The trochanter of the affected side is outwardly convex upwards. Medical staff can use the following physical examination programs to evaluate and diagnose:
  5. The hip joint is unstable and can be dislocated outwardly or can be reduced.
  6. The affected hip joint does not move synchronously with the pelvis.
  7. When the legs are bent at 90 degrees, the affected side is lower. X-ray examination is not very helpful for infants aged 3 to 4 months, generally used to analyze and judge the condition of skeletal dysplasia. If there is only dysplasia, the above examinations are not easy to detect.
