Medico-legal considerations for Morel-Lavall ée lesions

We describe the case of a 24-year-old motorcycle driver who was hit by a car. Clinically, the right lumbar region had a large 16 × 15 cm ecchymosis with subcutaneous fluid swelling found by palpation. A body scan revealed a Morel-L avallée lesion among other lesions. On day 7, its thickness was decreased by half. Morel-Lavallée lesions are specifically induced by shearing force with moderate-to-high kinetics in an anatomical area with an underlying fascia. The associated functional disability is globally moderate, but a larg e lesion or recurrences can extend the time needed to recover. Apart from some exceptions, care without any delay in diagnosis and treatment allows evolution of the lesion without functional consequences, but these lesions are frequently unnoticed in the initial phase.
