Anatomy and morphometry of the distal gracilis muscle tendon in adults and foetuses

Abstract

Ten human gracilis muscles obtained from adults and ten gracilis muscles collected from human foetuses between the 15th and 21st week of gestation were examined. The results of this preparatory study show that the gracilis muscle in adults is narrow and long - 482 mm on average. The distal tendon of gracilis muscle is long, 294 mm on average. It can be divided into two sections - external part, outside the muscle belly, and internal, intramuscular, part. The latter one is partially covered by muscle fibres and some of it is completely hidden inside the muscle belly, which is on average 76 mm long. Presence of an intramuscular part of the distal tendon was also demonstrated in the foetal material. Moreover, very strong correlations between particular muscle lengths were noted in foetuses.

Anatomical and topographical features of the gracilis muscle of the thigh from the position of using it for autotransplantation

“…An analysis of the literature data shows that the average width of the muscle part of m. Gracilis at its base, in the middle and at the end is 34.5±6.395, 26.3±4.682, 17.4±3.527 mm, respectively. At the same time, Dziedzic DW, et.al [8] and Rajeshwari MS, Roshankumar BN indicated the width of the belly of m. Gracilis 31.9 and 39 mm only, respectively [15].…”

An assessment of the variation of the intramuscular innervation of the gracilis muscle, with the aim of determining its neuromuscular compartments

“…The neural supply comes from the anterior branch of the obturator nerve, and its vascularity mainly from the deep femoral artery and medial circumflex femoral artery. The innervation and blood supply of the GM have been described previously (An et al, 2016; Crystal et al, 2005; Dziedzic et al, 2018; Fattah et al, 2013; Kumar et al, 1998; Kwon et al, 2009; Macchi et al, 2008; Magden et al, 2010; McKee et al, 1990; Meyers et al, 2005; Morris & Yang, 1999; Yan et al, 2019; Yu et al, 2010). Such knowledge is very valuable in planning transplant surgeries.…”
