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

Abstract

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.
