An unusual clinical presentation of nontraumatic myositis ossificans: Leg length discrepancy

Abstract

Functional leg length discrepancy results from soft tissue tightness or weakness across any joint in the lower extremity or spine. Herein, we present a 23-year-old female patient with leg length discrepancy due to a nontraumatic myositis ossificans (MO). Interpretation of the imaging findings is quite decisive in diagnosing soft tissue pathologies. It is particularly valid for MO to differentiate from other malignant or infectious lesions. There is no consensus on the treatment of nontraumatic MO. Although there are studies stating the contrary, surgical interventions should be considered as second option for patients who failed with nonsurgical treatments such as physical therapy.
