Avascular Necrosis of Head of Femur in Dyskeratosis Congenita - A Rare Presentation.

Avascular necrosis of head of femur is a rare presentation in Dyskeratosis Congenita (DC). Aplastic anaemia, increased susceptibility to infections and fatal pulmonary complications often complicate the clinical scenario in these patients leading to short life span and difficulty in performing surgical interventions. The diagnosis initially and subsequent management by total hip replacement posed a great challenge. To our knowledge this is the first case report of any intervention in form of total hip Arthroplasty done in DC. At 5 years of follow up the patient is asymptomatic with no radiographic signs of loosening or lysis.
