Abstract
Aims: To assess the long-term outcomes of Core decompression, progression in the stage of avascular necrosis and requirement of Total Hip Replacement following core decompression of Femoral head.
Methodology: In this observational study, we included 89 hips in 51 patients (33 men, 18 women) who underwent Core decompression for Avascular Necrosis of Femoral Head.Preoperative evaluation using hospital records and post operative evaluation using Harris Hip score was done. The disease was classified according to Ficat staging system.
Results: Out of 89 hips, 24 showed radiological progression at 09-month followup and 42 hips showed progression at 03 years. 17 hips had to undergo Total Hip replacement at 03 years.There were no major complications. 12 Hips had excellent score, 53 Hips had good score ,5 hips had Fair score and 19 hips showed poor score at the end of follow up.
Conclusion: The procedure is highly recommended in stage 1 disease as the statistical analysis shows significant improvement in hip scores. Clinical results of core decompression surgery are very encouraging in stage 1 and stage 2 of the disease; but not so favorable if done in stage 3.
