Orthopedics Questions? Ask an Orthopedist for Answers ASAP
I am an Orthopaedic surgeon and I would be happy to help you today.
You are probably describing an injury which goes by the name of Morel-Lavallee lesion named after french surgeon who first described it. It involves degoving of large part of skin of thigh and pelvis from underlying tissue with fluid collecting between the skin and underlying tissue as a result of trauma.
Orthopaedic surgeons treat this injury . You may be having difficulty getting proper treatment as this is not a common injury.
I would suggest that you visit Orthopaedic surgery department in a teaching hospital associated with a university .Senior surgeons at these hospitals have much larger experience especially in polyrauma patients who get this injury more frequently.Most of times surgical treatment is required.
Feel free to ask any follow-up questions.
