Indocyanine Green–Based Fluorescence Imaging to Guide Local Tissue Rearrangement of a Complex Morel–Lavallee Lesion About a Hip: A Technical Trick

Summary: Morel–Lavellee (ML) lesions are challenging injuries that can be complicated by persistent fluid collection and superimposed infection. The use of indocyanine green (ICG)–based fluorescence in orthopedic trauma continues to advance. ICG can be used to assess tissue perfusion and guide local tissue rearrangement. Perforating vessels can be easily identified and protected without the use of microvascular techniques, which can augment traditional keystone island perforator flap techniques. This case presentation and accompanied video demonstrate the use of ICG-based fluorescence to guide local tissue rearrangement to successfully treat an infected complex Morel–Lavellee lesion about a hip.
