Alcohol-induced multifocal osteonecrosis: a case report with 14-year follow-up

초록

Alcohol-induced osteonecrosis of femoral head is common but multifocal osteonecrosis secondary to alcohol is very rare. The authors report one case of multifocal alcohol-induced osteonecrosis involving both hips and both knees and its subsequent progression and management over a period of 14 years. There was bilateral involvement of hips in pre-collapse stage for which a core decompression was done. The left hip responded well and at 14-year follow-up was asymptomatic with full range of motion. The core decompression surgery failed in the right hip within 1 year and subsequently hybrid total hip replacement arthroplasty was done with good functional results at 13 years follow-up. The diagnosis of knee osteonecrosis was most probably missed initially and was subsequently diagnosed 6 months back due to symptoms of pain and radiographic findings for which a core decompression was done with good early results. The results of treatment of hip was excellent in our patient and despite the rarity, a high degree of suspicion and regular screening is necessary to detect involvement of other areas like the knee in alcohol-induced osteonecrosis.
