[PART 2] A gentleman was injured in a road traffic accident when the oil tanker in which he was travelling overturned and he got crushed beneath the tanker. 

The wound was covered with latissimus dorsi muscle flap.The latissimus dorsi muscle is the largest muscle in the body, up to 20 by 40 centimeters, allowing coverage of extremely large wounds. In spite of its size, no significant donor functional deficit results from removal of the muscle. It is the largest flap that can be harvested on a single predicle, and can even be combined with the serratus, scapular or parascapular flaps, to create a flap complex that can cover massive wounds. In the normal population the muscle is quite thin, allowing it to be draped over irregular surfaces with ease. When re-innervated using the thoracodorsal nerve, the latissimus can be used as a functional muscle.Credit: Dr. N. Jithendran
