Avascular necrosis of femoral head in Wilsons disease

Abstract

Introduction: Wilson disease is an autosomal recessive disorder which is due to mutation in gene encoding for ATPase. Due to excessive copper accumulation in various organs, it can present with spectrum of hepatic, neurological, osteoarticular changes most common being arthiritis. Diagnosis is confirmed on clinical features and genetic testing. Case presentation: We present a case of 25year old male, diagnosed with Wilsons disease on genetic testing with complaints of both hip pain and restricted movements. Further radiological evaluation was suggestive of avascular necrosis of both hips (grade 3 on left and grade 2 on right Ficat-Arlet staging). He underwent core decompression of right hip which relieved his symptoms of pain on right side and was counselled for bilateral total hip arthroplasty at a later date. Conclusion: With varied clinical manifestations of Wilsons disease being encountered, avascular necrosis of femoral head should be kept as a differential diagnosis in cases of hip pain.
