Morel-lavallee lesion - causes, signs and symptoms, investigation, treatment
A Morel-Lavallee Lesion (MLL) is a closed traumatic soft tissue degloving injury characterized by separation of the dermis from the underlying fascia due to a shearing force.
Diagnosis requires high a index of suspicion with presence of an area of ecchymosis, swelling, fluctuance and skin hypermobility in the polytrauma patient with underlying fractures.
Treatment is generally operative irrigation and debridement for most lesions given the proximity to planned surgical incisions and increased risk of infection.
