Transient Osteoporosis of the Hip: State of the Art and Review of Literature

Abstract

Transient osteoporosis of the hip (TOH) is a rare condition that causes sudden pain related to bone marrow edema of the hip. It is a benign disease and usually has a self-limiting course and resolution. Orthopedic literature on this topic is poor and no guidelines or algorithm has been proposed yet. TOH remains a poorly understood topic which happens to be often clinically underestimated. This paper aims to provide an up to date of the current knowledge through a literature revision. Info about TOH from etiology to treatment have been collected in order to guide the orthopedic surgeons among the clinical presentations and the best combination of therapies.
