- Abstract: 594Med J Malaysia Vol 75 No 5 September 2020SUMMARYMorel-Lavallee lesions (MLL) are post-traumatic, closedinternal degloving injuries that can result in severecomplications if not diagnosed early. It is conventionallyseen in cases of the high energy injuries of the pelvis andlower limb. The accumulation of extravasated blood,secondary to fracture and soft tissue damage may causeinternal degloving injury, skin necrosis, soft tissue damageand acute osteomyelitis. We report here the clinical andradiological features in a 32-year-old male referred from theemergency department of a tertiary hospital who hadsustained high energy motor vehicle accident. Onexamination, there was a fluctuant, mobile, non-tendersubcutaneous mass over the distal arm with suspicion ofinternal degloving injury. Plain radiographs showed nofractures. Ultrasound showed a fluid collection with thepresence of septations and echogenic debris within thecollection. Extravasation was noted between subcutaneoustissue layer and fascia at the posterolateral aspect of thearm. Wound debridement under general anaesthesia wascarried out. Intraoperative findings reported a significantamount of thick serous fluid with necrotic debris. Unhealthyskin and fat layers were debrided. Underlying muscles werefound to be healthy. The results of the intraoperative fluidculture and sensitivity showed no growth. Negative pressurevacuum dressing was carried out. After five cycles ofvacuum dressing, the wound showed signs of healing withan improved range of motion of the elbow. Orthopaedicsurgeons need to be vigilant of the possibility of MLL in theupper limb as a differential diagnosis in the management ofhigh energy trauma.
