Which donor site is cited as an example for a free flap in lower-extremity reconstruction?

• A. Rectus abdominis free flap
• B. Latissimus dorsi free flap
• C. Gracilis free flap
• D. Vastus lateralis free flap

Answer: (B)

The main idea is that some donor sites provide reliable, versatile tissue with a dependable blood supply for free flap reconstructions in the leg. The latissimus dorsi free flap is a classic example because it offers a large amount of well-vascularized tissue and a long, reliable pedicle (the thoracodorsal vessels), which gives surgeons a generous arc of rotation to reach leg defects. The muscle is robust and can be used as muscle-only or combined with skin, making it adaptable for various lower-extremity needs. Donor-site morbidity is generally manageable, and the flap can cover sizable defects in the leg, which is why it’s frequently cited in discussions of free flap options for limb reconstruction. While other donor sites like rectus abdominis, gracilis, or vastus lateralis are useful in different scenarios, the latissimus dorsi stands out as a widely used, dependable choice for leg soft-tissue coverage.
