Avascular Necrosis of the femoral head-AVN

Avascular Necrosis of the femoral head-AVN

Avascular necrosis (AVN) of the femoral head is a devastating disease that often leads to the destruction of hip joint. New and Minimally Invasive Modality for the Treatment of Avascular Necrosis of the Femoral Head is  insertion of bone merrow cell through the core of the bone.Core decompression of femoral head is the most common conservative surgical treatments where an 8-10mm cylindrical core of bone is removed from antero-lateral segment of the femoral head. But it is applied only in early stages of the disease and efficacy of this process are still controversial and most of patients ultimately require total hip arthroplasty. Application of Laser stimulates the reparative process with in the bone while local hyperthermia is produced by the laser vaporizes some of necrotic areas results a reduction of the intraosseous pressure which is the fulcrum of AVN regardless of its cause.Core decompression by Laser osteoperforation has been proven to be an effective, safe and minimally invasive treatment modality for AVN of the femoral head at this modern edage.
