Transient Osteoporosis of the Hip: A Case Report

Asl Abu-Nayla et al. Cureus. .

Abstract

Transient osteoporosis of the hip (TOH), also known as bone marrow edema (BME), is an uncommon condition of unknown etiology. While transient osteoporosis usually affects the hip, it could affect other joints as well. The most common presentation is pain and it has been linked to reduced bone mineral density. This self-limiting disease predominantly affects middle-aged men and pregnant women in their third trimester, presenting unique challenges in diagnosis and management. The exact cause of TOH remains uncertain, with theories suggesting vascular disruption, altered bone remodeling, and neurovascular influences as potential factors.

Keywords: avascular necrosis (avn); bone marrow edema; diagnosis; magnetic resonance imaging (mri); transient osteoporosis of the hip (toh).
