PURPOSE: To study the clinical presentation of femoral @entity135 (ONFH). Publications dedicated to this aspect of ONFH are rare. Our aim was to systematically collect and describe the clinical data. METHODS: A prospective survey was conducted in a cohort of ONFH recruited from a dedicated clinic for @entity2530 . The history of symptoms, medical management, and physical findings were obtained from 88 @entity1 suffering from 125 ONFH. Subgroups were formed: bilateral versus unilateral ONFH, radiological stages 1-2 (pre-fractured) versus fractured stage 3 versus stage 4. RESULTS: ONFH was bilateral in 63  %, especially in @entity228 users and in sickle-cell cases. These @entity1 were younger but had similar BMIs compared to the unilateral cases. The @entity158 was mechanical in 79  % of @entity572 and inflammatory in 21  %. Acute @entity158 at the onset was present in 55  % of @entity572 . The localization of this @entity158 was variable, including in the groin, the buttocks, or diffused in the lower limbs. A limp was present in 50  % of the @entity1 , only when one hip was @entity158 . The physical examination of the hip was normal in 31  %, especially in stages 1-2 (55  %). The diagnosis delay was 12  months, with inadequate medical management in 51  % of @entity1 . CONCLUSIONS: In ONFH cases, no typical clinical pattern was found. The clinical presentation was very variable, sometimes having spine or knee symptoms with a normal physical examination of the hip. ONFH should be systematically suspected in cases of onset of @entity158 in the pelvis, buttocks, groin, and lower limbs.

A prospective cohort study of the clinical presentation of non-traumatic XXXX of the femoral head: spine and knee symptoms as clinical presentation of hip @entity2530 .
