Morel Lavallee Lesion: A Shear Fascia-Nating Soft Tissue Injury, Isaac F. Su, James A. Espinosa, Alan A. Lucerna

Rowan-Virtua Research Day

Morel-Lavallée lesions (MLLs), first described by their namesake, French physician Victor-Auguste-François Morel-Lavallée, in 1863, represent a distinct category of soft-tissue degloving injuries. These injuries occur when a shearing force disrupts the connection between subcutaneous tissue and fascia, severing lymphatic vessels and capillaries, and leading to an encapsulated collection of lymph, blood, and necrotic fat. Because this space is deep and enclosed, the fluid accumulation cannot easily drain or resolve spontaneously and often an inflammatory capsule develops, further inhibiting resorption. Undiagnosed, patients go on to develop chronic pain, infection, skin necrosis, progressive neurovascular deficits, and, in severe cases, potential loss of …

Deep Tissue Pressure Injury (DTPI): Predictors and Risk Factors During Hospitalization. A Literature Review

Tricia Foley, RN, BSN, CWOCN, MMC

Background: Deep tissue pressure injuries (DTPI) at Maine Medical Center (MMC) have increased from 2014 to 2016. DTPI initially appear as purple or maroon discoloration and either resolve or evolve into a deeper wound. When a DTPI evolves into an eschar, this is called an unstageable pressure injury by the National Pressure Ulcer Advisory Panel. Patients with an unstageable, stage 3 or 4 pressure injury are reported to the State of Maine according to Maine Law. This is considered a …
