Hip Impingement Syndrome (HIS) is a condition in which the structural mismatch between the acetabulum and the femoral head and neck joint is abnormal, resulting in significant pain when the hip joint is in motion. Due to the structural mismatch between the acetabulum and the femoral head and neck joint area, the two will have abnormal friction or even collision when the hip joint is moving, and the main symptom is chronic hidden pain in the hip joint and limitation of activities, which can be aggravated by prolonged walking or strenuous exercise. Clinically, this phenomenon is called hip impingement syndrome. Hip impingement syndrome can be categorized into three types according to the different parts of structural abnormalities, i.e. concave wheel impingement, pincer impingement and mixed impingement, and the abnormal structures are the abnormal bony protrusion of the femoral head and neck union area, the abnormal development of the acetabulum, and the co-existence of both of the above. If the diagnosis of hip impingement syndrome is clear, it is recommended to standardize the treatment under the guidance of doctors.
