Necrosis of the femoral head and increased pain after functional exercises may be caused by incorrect functional exercises that increase the burden on the femoral head and cause the femoral head to collapse.
Necrosis of the femoral head refers to a disease in which the blood supply to the femoral head is damaged or interrupted, resulting in the death of bone marrow components and bone cells and subsequent tissue repair, which in turn leads to structural changes and collapse of the femoral head, causing pain and dysfunction of the patient’s hip joint.
Patients with necrosis of the femoral head should do non-weight-bearing hip flexion and extension exercises, which will not lead to continuous stress stimulation of the femoral head, and therefore can slow down the development of necrosis of the femoral head to a certain extent.
If the patient does not do the functional exercise in a correct way, such as playing soccer, basketball, running and other sports, which increases the burden on the femoral head, accelerates the necrosis of the femoral head, and causes the collapse of the femoral head, it will lead to the local pain aggravation after the functional exercise.
It is suggested that patients should carry out reasonable functional exercises under the guidance of doctors, and should also quit smoking, alcohol, and avoid the use of hormone drugs in order to avoid aggravation of symptoms.
