Simultaneous occurrence of a severe Morel-Lavallée lesion and gluteal muscle necrosis as a sequela of transcatheter angiographic embolization following pelvic fracture: a case report
Abrupt traumatic separation of the skin and subcutaneous fatty tissue from the underlying fascia is termed a closed degloving injury. This was first described by Morel-Lavallée in the mid 19th century, and he was later credited with the eponym by Letournel and Judet in their classification of acetabular fractures. They referred to closed degloving injuries over the region of the greater trochanter as Morel-Lavallée lesions. Such trauma is often but not always associated with pelvic and acetabular fractures. Clinical manifestation varies, hence diagnosis is often delayed. Small Morel-Lavallée lesions may present with a soft fluctuant swelling over the thigh, skin hypermobility, and loss of cutaneous sensation. Larger lesions may manifest as skin necrosis, or as wound sepsis. We report on a patient who suffered bilateral Morel-Lavallée lesions and resultant septic shock after severe closed bony pelvic trauma.
