Anatomical and topographic features of fascia of the gluteal-femoral region in the common lynx

The  article  presents  anatomical  features of the superficial and deep fascia, in particular on the pelvic limb of the common lynx, which are absent in the available literature. The material for the research was a sectional material - pelvic limbs (n= 6), selected from the common lynx, without external signs of pathologies  of  the  musculoskeletal  system. Methods of fine macro- and microanatomic dissection of the lynx's left pelvic limb were used. At the same time, a functional analysis of  the  studied  structures  and  skeletotopic projection  of  muscles,  fascia  and  fascial nodes  were  carried out.  Based  on  the  conducted  studies,  it  was  found  that  the  deep fascia is separated from the superficial fascia by an interfacial space filled with loose connective (or fatty) tissue. In the pelvic limb area, it is represented by the gluteal-femoral fascia, and on the lower leg it continues as the deep fascia of the lower leg. In the process of dissecting the deep fascia, we noted that  in  the  gluteal  region,  the  deep  gluteal fascia is fixed on the supracosteal ligament, in the area of the root of the tail, along the tail fold and up to the sciatic tubercle. We noted  that  the  deep  gluteal  fascia  begins from the vertebral head of the biceps femoris muscle and, in the cranial direction, covers successively the posterior, superficial gluteal and caudal part of the middle gluteus muscle. Along the way, the perimysium of the above muscles are interwoven into it, however, in the area of the iliac wing, it fuses with  the  perimysium  of  the  middle  gluteal muscle  and  then  continues  into  the  lumbar fascia. At the same time, it forms a fascial node in the maklok area. Distally, the deep gluteal fascia continues as the deep femoral fascia. The data obtained are the reference in assessing the structural and functional state of the fascial formations of the pelvic limb in the common lynx.
