Hip replacement does not technically "cure" avascular necrosis, but it effectively eliminates the symptoms and restores normal hip function in advanced cases. Avascular necrosis (AVN), also known as osteonecrosis, is a condition where bone tissue dies due to lack of blood supply.
While hip replacement surgery cannot regenerate the dead bone tissue or restore the original blood supply, it provides a definitive solution by replacing the damaged bone and cartilage with artificial components, effectively eliminating pain and restoring mobility.
Avascular necrosis occurs when blood flow to the femoral head (the ball-shaped top of the thigh bone) is disrupted, causing bone cells to die and eventually leading to collapse of the joint surface. Several factors contribute to AVN:
Avascular necrosis progresses through distinct stages, and the treatment approach varies based on the stage at diagnosis:
Before considering hip replacement, hip preservation surgery offers options for early-to-mid stage AVN. Dr. Gourineni's approach uses bisphosphonate injection therapy and other preservation techniques to protect the femoral head from deformation in early stages.
