Morel-Lavallée lesion
Pronunciation: mor-EL la-val-AY
Closed degloving injury causing separation of subcutaneous tissue from underlying fascia with fluid collection.
Full Definition
A Morel-Lavallée lesion is a post-traumatic closed degloving injury that occurs when significant shear forces separate the subcutaneous tissue from the underlying fascia, creating a potential space that fills with blood, lymphatic fluid, and liquefied fat. These lesions commonly occur over the greater trochanter, knee, or lumbosacral region following high-energy trauma. The condition can complicate fracture management by creating infection risk and wound healing problems. Early recognition and appropriate management, including drainage and debridement, are essential to prevent complications in associated orthopedic injuries.
