Estudo descritivo comparativo da anatomia do músculo tensor da fáscia lata em macaco prego (Sapajus apella) e canídeos neotropicais / Comparative anatomy of the fascia lata tensor muscle in capuchin monkeys (Sapajus apella) and neotropical canides

A Anatomia comparativa vem se destacando nos tempos, como recurso que permite a avaliação da evolução de determinadas espécies, evidenciando suas adaptações ao meio em que vive. Com a intervenção humana, no bioma do cerrado diversas espécies entraram ou se encontram em vias de entrarem em risco de extinção sem nem ao menos terem a sua biologia estudada. Este trabalho visa descrever e comparar a anatomia do músculo tensor da fáscia lata de macaco-prego e canídeos neotropicais. Para tanto, foram utilizados dois espécimes de cada grupo taxonômico: macacoprego; raposa-do-campo; cachorro-do-mato e lobo-guará, comparando os resultados encontrados entre si, com a literatura humana e veterinária já bem estabelecidas. Os animais foram fixados em solução aquosa de formol a 10%, e dissecados sob técnicas usuais de dissecação utilizadas em Anatomia macroscópica, seguido de foto documentação. O músculo tensor da fáscia lata não apresenta divergências entre as espécies estudadas, possuindo formato aproximadamente triangular e localização na parte proximal da face lateral da coxa, constituído por uma parte cranial e outra caudal. As principais diferenças estão relacionadas, com o porte físico-postural de cada grupo, certamente atrelado ao modo de vida.

The comparative anatomy has been assuming an important role during the last decades as a tool that allows evaluatingthe evolution of certain species, showing their adaptations to the environment they live in. Due to human intervention in the cerrado biome, several species have been or are about to be endangered without even having their biology studied. This study aimed to describe and compare the anatomy of the Fascia Lata Tensor muscle in capuchin monkeys and neotropical canides. For such purpose, two specimens of each taxonomic group (capuchin monkey, field fox; forest dog and maned wolf) were used. The obtained results were compared among the studied species and discussed with the human and veterinary literature data, which are already well established. As the focus of this study was on the descriptive anatomy rather than on the statistical data, the dissection of a larger number of animals was not required. The pieces were fixed in 10% formalin aqueous solution, using dissection routine techniques in macroscopic anatomy. Next, the pieces were analyzed, described and photographed. Regarding the shape and location the fasciae latae tensor muscle presented no major differences, having an approximately triangular shape, locating in the proximal part of the thigh lateral side and comprising a cranial portion and another caudal one, both fleshy. The main differences were related to the postural-physical size of each group, certainly linked to the lifestyle.

Anatomical and Radiological Study of the Vascular Distribution and Skin Territory for the Tensor Fasciae Latae Free Flap / 대한해부학회지

The authors studied the pattern of vascularization of the tensor fasciae latae muscle in 110 Korean cadavers using macroscopic dissection and radiographic methods. The location of the points in this study were expressed as XY coordination in reference to the line between ASIS (A) and lateral margin of the patella (B). The deep femoral artery was arised from XY coordination value X: 8.1 cm, Y: 5.5 cm. The length and external diameter of the deep femoral artery were 30.0 mm, and 5.6 mm, respectively. The most common pattern of the lateral circumflex femoral artery was from the deep femoral artery 81.4% (n: 176) and femoral artery 18.6% (n: 42). The lateral circumflex femoral artery was arised from XY coordination value X: 10.3+/-1.3 cm, Y: 4.6+/-0.8 cm and ended XY coordination value X: 10.5+/-2.3 cm, Y: 3.7+/-9.6 cm. Lateral circumflex femoral artery branched into ascending, transverse and descending branch. The length and external diameter of the lateral circumflex femoral artery was 21.2+/-12.9 mm, and 5.1+/-2.3 mm, respectively. The average number of branches, length and external diameter of pedicles to the tensor fasciae latae muscle were 3.9+/-3.5, 30.9+/-12.1 mm and 2.6+/-0.7 mm, respectively. The pedicle of the tensor fasciae latae muscle arised from XYcoordination X: 8.8+/-2.0cm, 1.8+/-0.9 cm and skin territory was 5x13 cm2 at 13 cm on the line AB. The pattern of distribution, arterial supply and territories of the tensor fasciae latae muscle obtained in this study will provide useful anatomical backgrounds for the free flap surgery.
