Functional Morphology of the Thoracic Limb in the Silky Anteater (Cyclopes didactylus): A Comparative Study With Tamandua tetradactyla

Acta Zoologica, EarlyView.
ABSTRACT The order Xenarthra presents unique morphophysiological adaptations related to its specialized ecological niches. This study investigates the functional morphology and comparative myology of the thoracic limb in Cyclopes didactylus (silky anteater) and Tamandua tetradactyla (southern tamandua) to elucidate how muscle arrangements support ...

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Assessment of Humerus Union and Shoulder Movement After Management of Humeral Shaft Fracture by Interlocking Nail [PDF]

Zagazig University Medical Journal
Background: Humeral shaft fracture makes up approximately 3% of all fracture types. Advantages of intramedullary nailing in management is considered a minor invasive surgical procedure can effectively shorten the operative time and hospital stay and ...

Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds

Journal of Anatomy, EarlyView.
The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Final outcomes of radial nerve palsy associated with humeral shaft fracture and nonunion

Journal of Orthopaedics and Traumatology, 2019
Background Little evidence regarding the extent of recovery of radial nerve lesions with associated humerus trauma exists. The aim of this study is to examine the incidence and resolution of types of radial nerve palsy (RNP) in operative and nonoperative

Intramedullary nailing of humeral shaft fractures: failure analysis of a single centre series

, 2015
Intramedullary nailing (IMN) is an accepted technique for the treatment of humeral shaft fractures. Previous studies published concerns over whether this technique had higher complication rates such as nonunion and technical failures compared to plate ...

Cumulative effects of lifelong systemic excess growth hormone on postcranial skeletal morphology in adult mice

Journal of Anatomy, EarlyView.
Our μCT‐based pilot study reveals size and shape disparity in the adult postcranial skeleton of growth‐hormone model (bGH) mice relative to wild‐type mice. bGH mice have larger and more sexually dimorphic bones, with a systemic radiodensity increase in bony sesamoids and associated, but typically uncalcified, soft tissues.

Anterolateral surgical approach for the treatment of humeral shaft fractures [PDF]

, 2022
Background: The posterior approach is the most commonly used approach for mid-shaft and distal humeral fractures. However, fixation via the posterior approach is associated with iatrogenic radial nerve palsy. The purpose of this study was to evaluate the
