Chandler's disease, also known as idiopathic avascular osteonecrosis of the femoral head (ANFH or ONFH), is a rare condition in which the bone cells in the head of the femur (FH) die due to lack of blood. This disease is caused when blood flow is reduced to the part of a bone near a joint.

This process takes place over months to years and eventually causes disabling arthritis, particularly of the femoral head (hip). [2] Dysbaric osteonecrosis lesions are typically bilateral and usually occur at both ends of the femur and at the proximal end of the humerus. Symptoms are usually only present when a joint surface is involved, which ...
When an LCP disease diagnosis occurs after age eight, a better outcome results with surgery rather than nonoperative treatments. [20] Shape of femoral head at the time when Legg-Calvé Perthes disease heals is the most important determinant of risk for degenerative arthritis; hence, the shape of femoral head and congruence of hip are most ...

In this case, the lesion was caused by avascular necrosis of the bone just under the cartilage.

In this instances, it is a more conservative treatment, and in the long term can postpone the need for a hip replacement. [11] In the later stages of osteonecrosis (3 through 6), where the bone has begun to collapse or has fully collapsed, the Phemister graft is not recommended. [9] [12]

Osteonecrosis risk may also be increased by common immunosuppressants like cyclosporine and tacrolimus, due to the induced vasoconstriction. Drugs such as sirolimus may potentiate this effect by similar action or influencing the lipid profile.
