Isolated Acetabular Osteoporosis in TOH in Pregnancy: A Case Report

Authors: U K. Debnath, FRCS, R Kishore, MRCS, R J. Black, FRCS


Transient osteoporosis of the hip (TOH) is a rare, self-limiting syndrome characterized by hip pain in the 2nd or 3rd trimester of pregnancy. Conventional radiography shows demineralization of the femoral head. Diagnosis is confirmed by MRI scan. Over the course of a few months, the radiological abnormalities and the pain disappear spontaneously with complete resolution. We report the case of a patient with isolated acetabular involvement during pregnancy, confirmed by MRI scan, who obtained spontaneous remission of her symptoms.

Key Points

* TOH in pregancy usually affects the femoral head.

* Isolated acetabular involvement is rare and is a self limiting disease.

* Early MRI scans are the mainstay of diagnosis.

* Treatment includes non-weight bearing for six weeks along with calcium supplementation and NSAIDs.
