Treatment of these conditions includes treating the resultant pain, stiffness, and limitations ofmovement surgically with bone grafts both vascularized and non-vascularized andarthroplasty inmost advanced stages.  \nMaterials and Methods: In a duration of 2 years, five patients were treated for such pathologies using vascularized bones (pedicled or free). All of them were subjected to radioisotope (Technetium 99m) scan postoperatively to evaluate the viability of the transferred bones. The post-operative pain was assessed using visual analog scale (VAS) to assessthe outcome of treatment by comparing the scorebefore and after surgery.  \nResults: All patients improved symptomatically as per the outcome assessment with VAS score with viability of the transferred bones as evidenced by radioisotope scan.  \nConclusion: Vascularized bone transfer is indispensable in the treatment of avascular necrosis of bone and the complications thereof, and should always be offered primarily to younger patients especially.  \nKeywords: Avascularnecrosis of bone, vascularized bone graft, osteonecrosis of femoral head, scaphoidfracture non-union.  \nIntroduction  \nAvascular necrosis (AVN) of bone, affecting various components of human skeletal system, is not uncommon in clinical practice. Commonly involved regions include theepiphyses of long bones at the weight-bearing site. Head of the femur is most commonly involved, followed by knee, talus, and small bones ofwrist, such as lunate and scaphoid. AVN results from a myriad ofcauses, ofwhich, common onesinclude trauma, chemo-radiation, and hematological disorders such as coagulopathies and sickle cell disease. Corticosteroid intake is also one of the common causes of this pathology. Treatment  \nmodality of this condition, by and large, is governed by the stage of the disease. Itvaries from conservative management with nonsteroidal anti-inflammatory drugs to advanced form of surgical management, like arthroplasties. In younger patients with advanced stage of AVN affecting major joints, arthroplasty isnot considered ideal, as the procedure most often needs to be repeated after about two decades. Hence, for these groups of patients, debridement of necrotic bone and replacing it with vascularized bone graft is considered tobe the most appropriate treatment to alleviate the symptoms of pain, stiffness, and limitations ofmovement and also prevent further complications.
