Transtibial transposition of gastrocnemius muscle and musculocutaneous flaps.

The medial and lateral gastrocnemius muscle flaps have become the workhorses of proximal calf reconstruction since their initial description by McCraw et al. in 1977. Since that time many authors have presented varying and often ingenious techniques by which the range of these flaps can be expanded. This report adds another modification of the standard gastrocnemius muscle flap: transtibial transposition of the muscle through the posterior cortex.
