Abstract

We report a case of a 31-year-old man who developed a non-simultaneous bilateral transient hip osteoporosis (THO) complicated with an atraumatic undisplaced pathological femoral neck fracture (FNF) of his left hip. He was successfully treated with internal fixation on the left hip, and a follow-up Magnetic Resonance Imaging evidenced satisfactory resolution on the right side. Diagnosis and management of THO are usually challenging as symptoms before pathological FNFs might be misdiagnosed. This case highlights the importance of suspecting pathological FNFs when pain persists despite conservative treatment. Finally, surgical treatment is strongly recommended if a pathological FNF is confirmed.

Level of evidence: Level IV.
