■➜ Reconstructive options 23. B, D, E A large scalp defect with bone tissue removed cannot be repaired by a rhomboid flap but would require reconstruction with a free flap. Heel ulcers are difficult due to their site, but can be treated by employing a pedicled instep flap.

Wounds of the ankle and lower third of the leg can be repaired using fasciocutaneous or free flaps. Doppler apparatus is an easy and good way to identify perforating vessels on the skin surface.
