Why does hip dysplasia occur?

Hip dysplasia may be caused by non-disease factors or disease-related factors, such as trauma, osteogenesis imperfecta, and others. The specific analysis is as follows:

I. Non-disease factors

Abnormal or incomplete hip joint development during the embryonic period, weakening of the quadriceps and gluteal muscles, ligamentous laxity or excessive tightness, and prolonged poor posture may all contribute to hip dysplasia.

II. Disease-related factors

1. Trauma

During childhood and adolescence, growth plates and ligaments and other soft tissues have not fully matured. If injured by external forces and not treated promptly and effectively, damage to the hip's growth plates and soft tissues may occur, disrupting normal hip joint development and leading to hip dysplasia.

2. Osteogenesis imperfecta

In patients with osteogenesis imperfecta, the hip joints are prone to fractures, deformities, and structural defects, which impair normal hip development and function, ultimately resulting in hip dysplasia.

In addition, degenerative hip joint disease, rheumatoid arthritis, ankylosing spondylitis, and other conditions may also cause hip dysplasia. It is recommended that treatment be administered under the guidance of a qualified physician according to the specific condition, including external fixation or surgical interventions such as hip replacement or proximal femoral shortening osteotomy, to alleviate symptoms.
