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] Complications may include collapse of the bone or nearby joint surface. [1]
Pain in the affected area [1] [2] Muscle spasm in the affected area [1] Numbness and tingling in an arm or leg [1] [2] Paleness [1] [2] of the skin of the arm or leg; Muscle weakness of an arm or leg, [1] [2] possibly to the grade of paralysis [2] Later symptoms are closely related to infarction of the tissue supplied by the occluded artery:
Cancellous bone, with its mesh like structure and spaces filled with marrow tissue is more susceptible to damage by bone infarcts, leading to hypoxia and premature cell apoptosis. [15] [16] [27] [28] The mean life-span of osteocytes has been estimated to be 15 years in cancellous bone, [29] and 25 years in cortical bone.
Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply.The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque), compressed by something outside of the vessel causing it ...
Bone pain originates from both the periosteum and the bone marrow which relay nociceptive signals to the brain creating the sensation of pain. Bone tissue is innervated by both myelinated (A beta and A delta fiber) and unmyelinated sensory neurons. In combination, they can provide an initial burst of pain, initiated by the faster myelinated ...
Freiberg disease is a rare condition that affects the second metatarsal head, leading to pain and potential deformity. It is often associated with activities that ...
Enchondroma is a type of benign bone tumor belonging to the group of cartilage tumors. [1] [2] There may be no symptoms, [3] or it may present typically in the short tubular bones of the hands with a swelling, pain or pathological fracture.
Osteomyelitis (OM) is an infection of bone. [1] Symptoms may include pain in a specific bone with overlying redness, fever, and weakness. [1] The feet, spine, and hips are the most commonly involved bones in adults. [2] The cause is usually a bacterial infection, [1] [7] [2] but rarely can be a fungal infection. [8]
