Core Decompression with Non Vascularized Fibular Graft as Modern Surgical Treatment of Early Hip Avascular Necrosis.

Abstract

Cellular death of bone due to impairment of the blood supply leading to collapse resulting in pain, and loss of joint function is known as avascular necrosis (AVN). The head of femur is the most common bone affected by avascular necrosis followed by talus and scaphoid. We evaluate the results of core decompression with non-vascularized fibular graft in avascular necrosis of femoral head. This quasi experimental study was done at Mymensingh Medical College Hospital, Dhaka Medical College Hospital and some other private hospitals of Bangladesh. The study includes patients who underwent core decompression and non-vascularized fibular grafting in avascular necrosis of femoral head from January 2017 to December 2018. In this study we evaluated total 20 patients and majority of the patients belongs to the group of 20-30 years. Out of 20 patients, 8 of them were unilaterally involved rest 12 had bilateral involvement. Out of 24 hips of bilateral involvement 4 were grade III and IV (Ficat and Arlet classification) therefore not included in the study. So, we study 28 hips only. The average success rate was 90% after core decompression and non-vascularized fibular bone grafting. Harris hip score of 60 on presentation had poorer outcome. Patients with less than 80 degrees of flexion had poorer outcome.
