What is bilateral femoral head avascular necrosis?
Avascular necrosis (AVN) of the femoral head is a pathologic process that results from interruption of blood supply to the bone. AVN of the hip is poorly understood, but this process is the final common pathway of traumatic or nontraumatic factors that compromise the already precarious circulation of the femoral head.
What causes avascular necrosis of the head of femur?
Avascular necrosis occurs when blood flow to a bone is interrupted or reduced. Reduced blood supply can be caused by: Joint or bone trauma. An injury, such as a dislocated joint, might damage nearby blood vessels.
What is the treatment for avascular necrosis of the hip?
In early stages of AVN (precollapse), core decompression with or without bone graft is typically considered the most appropriate treatment. In late stages, characterized by collapse, femoral head deformity, and secondary osteoarthritis, total hip arthroplasty is the most appropriate treatment.
What are the consequences of avascular necrosis of the femoral head?
Legg-Calve-Perthes is idiopathic avascular necrosis of the femoral head that affects pediatric populations. Lack of blood supply causes necrosis of the femoral head leading to a deformity that puts the patient at high risk of developing osteoarthritis and/or losing range of motion (ROM).
How serious is avascular necrosis?
Avascular necrosis is a localized death of bone as a result of local injury (trauma), drug side effects, or disease. This is a serious condition because the dead areas of bone do not function normally, are weakened, and can collapse.
Is avascular necrosis a disability?
Under Social Security Disability (SSDI) guidelines, there is no “listing” for AVN, and having AVN does not automatically entitle you to long-term disability (LTD) under SSDI or under a group disability plan provided by an employer (ERISA).
Do you need surgery for avascular necrosis?
Surgical and other procedures Because most people don’t develop symptoms until avascular necrosis is fairly advanced, your doctor might recommend surgery. The options include: Core decompression. The surgeon removes part of the inner layer of your bone.
