Abstract
Transient osteoporosis of the hip is a rare condition of unknown aetiology affecting middle aged men with no risk factors and women in their third trimester of pregnancy. The condition invariably resolves spontaneously, however, due to its rarity and initially normal plain radiographs, the syndrome is often not appreciated early in its development, and particularly represents a diagnostic problem of differentiation from osteonecrosis.
We present a case of unilateral transient osteoporosis of the hip in a 52 year old male and a case of bilateral hip involvement in a 32 year old female in her 35th week of pregnancy. Both cases include the initial and follow-up plain radiographs, MRI and DEXA scan findings, through to symptomatic resolution.
We present a literature review of the disease and analyse the current evidence on aetiology, the problems in diagnosis and the current treatment modalities.
