M93: Other osteochondropathies

M93.0: Slipped upper femoral epiphysis (nontraumatic)

The femur has an upper, middle and lower section. The upper section of the femur is connected to the pelvic bones by the hip joint. The upper section includes the neck and head of the femur plus 2 bony protrusions. The bony protrusions lie between the neck of the femur and its central section. The neck of the femur is set at an angle to the central section.

In children and adolescents the bone’s growth stems from the growth plates. There are growth plates in the long bones in the arms and legs, and the long bones in the hands and feet. There is a growth plate at each end of these bones.

If the femoral head shifts relative to the femoral neck in the growth plate, it can be painful. You may then no longer be able to walk properly, and limp.
