In early AVN without femoral head collapse, a total hip replacement is performed

In severe AVN with femoral head collapse, decompression by drilling is performed
|
|
|
In severe AVN with femoral head collapse, a total hip replacement is performed

Detailed explanation-1: -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.
Detailed explanation-2: -In the early stages of avascular necrosis, certain medications may help ease symptoms: Nonsteroidal anti-inflammatory drugs (NSAIDs). Over-the-counter medications like ibuprofen (Advil, Motrin IB, others) or naproxen sodium (Aleve) might help relieve pain associated with avascular necrosis.
Detailed explanation-3: -Core decompression. Core decompression is the most commonly performed surgical procedure for treatment of early ONFH. It decreases the intraosseous pressure in the femoral head and increases blood flow to the necrotic area, thus augmenting neobone formation [Figures 1 and 2].
Detailed explanation-4: -Femoral head avascular necrosis is the cause of paralyzing status of youth population. Initial diagnosis is the main element in treating the disease. Bone grafting and core decompression are the approved cures at the early steps of the disease. Hip replacement in a total manner is the common cure in the final stages.
