Stress fractures are typically discovered after a rapid increase in exercise. Symptoms usually have a gradual onset, with complaints that include isolated pain along the shaft of the bone and during activity, decreased muscular strength and cramping.
Avascular necrosis (AVN), also called osteonecrosis or bone infarction, is death of bone tissue due to interruption of the blood supply. [1] Early on, there may be no symptoms. [ 1 ] Gradually joint pain may develop, which may limit the person's ability to move. [ 1 ]
Radiographically, occult and subtle fractures are a diagnostic challenge. They may be divided into 1) high energy trauma fracture, 2) fatigue fracture from cyclical and sustained mechanical stress, and 3) insufficiency fracture occurring in weakened bone (e.g., in osteoporosis and postradiotherapy). Independently of the cause, the initial ...
Articular: Legg-Calvé-Perthes disease (or, avascular necrosis of the femoral head in the hip), Köhler's disease (of the tarsal navicular bone of the foot), Freiberg's infraction (of the second or third metatarsal of the foot and less frequently the first or fourth; sometimes called Freiberg's Infraction or Freiberg's disease), [10] Blount's ...
A hip fracture is a break that occurs in the upper part of the femur (thigh bone), at the femoral neck or (rarely) the femoral head. [2] Symptoms may include pain around the hip , particularly with movement, and shortening of the leg. [ 2 ]
Radiological signs of transient osteoporosis of the hip include localized osteoporosis of the femoral head and neck (Figure 8). Nevertheless, final diagnosis has to be made with MRI to differentiate it from avascular necrosis and from insufficiency or stress fractures of the femoral head or neck.
An open fracture (or compound fracture) is a bone fracture where the broken bone breaks through the skin. [2] A bone fracture may be the result of high force impact or stress , or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis , osteopenia , bone cancer , or osteogenesis imperfecta ...
Necrotic bone and inflammation histology slide. The current etiology or origin of this disease is unknown. Some studies theorized that bone remodeling is maintained in a microenvironment in the FH meaning that there is a greater local component to changes to the femoral head than the normal systemic way that bone remodeling is handled throughout the body.
