What is a Morel-Lavallee lesion?

• A. A type of herniated disc
• B. An intervertebral joint dysfunction
• C. A posttraumatic hemolymphatic collection of fluid
• D. A ligament injury

Answer: (C)

A Morel-Lavallee lesion is characterized as a posttraumatic hemolymphatic collection of fluid. This type of injury occurs when there is significant blunt trauma that separates the skin and subcutaneous tissue from the underlying fascia, leading to accumulation of blood and lymph fluid in the space created by this separation. It is typically seen in areas where there is a greater degree of soft tissue mobility and can present as a fluctuating mass in the subcutaneous tissue, often requiring careful assessment and management.

This lesion serves as a reminder of the complexities involved in managing soft tissue injuries post-trauma, as well as the potential for complications such as infection or continued fluid accumulation if not treated appropriately. Understanding this condition emphasizes the importance of a thorough evaluation and appropriate imaging, like ultrasound or MRI, to confirm the diagnosis and guide treatment options effectively.
