Which free flap donor site is given as an example in the material?

• A. Rectus abdominis free flap
• B. Gracilis free flap
• C. Latissimus dorsi free flap
• D. Tensor fasciae latae free flap

Answer: (C)

Latissimus dorsi is used as a representative example because it offers a large amount of tissue, a reliable and long vascular pedicle from the thoracodorsal vessels, and versatility in harvesting as muscle, myocutaneous, or fasciocutaneous flaps. This combination makes it a go-to option for covering sizeable defects and provides good reach and reliability, which is why teaching materials often cite it as a typical example. Other donor sites have more specific limitations—rectus abdominis carries abdominal wall morbidity concerns; gracilis is thinner and better suited for smaller defects or functional transfers; tensor fasciae latae can affect hip function—so they’re less commonly used as the default example in introductory material.
