Profunda femoris artery perforator flaps: a detailed anatomical study
Published in Journal of Plastic Surgery and Hand Surgery, 2020
Said Algan, Onder Tan
Hupkens et al. investigated proximal, middle, and distal part of the posterior thigh region anatomically using 12 fresh cadavers. Of the perforators, 69.1 and 30.9% consisted of the musculocutaneous and septocutaneous varieties, respectively. The primary origin of perforators was PFA 61.7%. Of the perforators, 52% were located in the middle third of the PTR. The PFA perforators were the longest with an average length of 13.7 ± 4.69 cm. The largest diameter of perforators was seen in the PFA (2.9 ± 0.98 mm). Musculocutaneous perforators consisted of 38.4% adductor magnus muscle, 23.0% gracilis muscle, and 23.07% biceps femoris muscle. However, this study included only perforators with a minimum diameter of 1 mm [2].

The use of the posterior thigh as donor site for autologous breast reconstruction was introduced in 2012 by Allen et al. They were the first to use the profunda artery perforator (PAP) flap for breast reconstruction. This flap is the perforator version of the posterior thigh myocutaneous flap used to reconstruct pressure sores. It is based on a perforator of the deep femoral vessels (profunda femoris artery and vein) coursing through the adductor magnus muscle. Advantages compared to the TUG/TMG flap are a longer pedicle, sparing the muscles and orienting the skin island away from the lymph nodes in the femoral triangle. Disadvantages are related to the transverse orientation of the flap [70].
Comparison of hip extensor muscle activity including the adductor magnus during three prone hip extension exercises

The adductor magnus muscle (Amag) is another primary hip extensors, along with the Gmax and hamstring muscles, for the following reasons. First, the Amag has an extensor portion, originating on the ischium and ischial tuberosity, as well as an adductor portion, originating at the inferior ramus of the pubis (Takizawa et al., 2014). Second, muscle fibers of Amag are closely related to the origin of semimembranosus and the fiber orientation of Amag is similar with hamstrings (Philippon et al., 2014). Third, the posterior head of the Amag muscle has the greatest moment arm for hip extension relative to other hip muscles (Neumann, 2010).
