The lateral margin of the Latissimus dorsi is separated below from the Obliquus externus abdominis by a small triangular interval, the lumbar triangle of Petit, the base of which is formed by the iliac crest, and its floor by the Obliquus internus abdominis.
It is bounded above by the Trapezius, below by the Latissimus dorsi, and laterally by the vertebral border of the scapula; the floor is partly formed by the Rhomboideus major.

 BioMed Central | Full text | The creation of new rotation arc to the rat latissimus dorsi musculo-cutaneous flap with ...
Reversed pedicled latissimus dorsi flap is obtained by elevation of the muscle from the segmental pedicle.
The aim of this study was to change the pivotal point of latissimus dorsi and create a new rotational arc in rats using vascular delay and thus to increase its use and to shorten the period of delay using chemical delay.
In this study, vascular delay in which first thoracodorsal artery, the main vascular pedicle of latissimus dorsi flap in the rats, was ligated and then separated had a strong effect on the flap survival and the flap could survive on the nondominant vascular pedicle.
