Hip inversion is a deformity of the hip bone. The normal hip joint has a cervical stem angle that averages 127 degrees. If it is less than this angle, the hip is internally rotated. Hip inversion can cause abnormalities in the biomechanics of the hip joint, which can lead to increased hip wear and accelerated walking abnormalities that need to be addressed. There are many causes of hip inversion, the most common cause is developmental, and orthopedic management may also be required for a previous injury to the hip or a fracture that has healed abnormally. Mild hip inversion can be treated by training the muscles around the hip joint, or can be kept under observation for the time being if the symptoms are relieved. If the angle of the hip is particularly large, conservative treatment may not be effective. If it affects the ability to walk, orthopedic surgery may be needed to correct it. Hip impingement is very harmful, if hip impingement occurs, it is necessary to go to the hospital in time for systematic diagnosis and treatment.
