Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...

A dual dimensional optimization strategy for automatic osteotomy preoperative planning in congenital radioulnar synostosis

Scientific Reports
Congenital radioulnar synostosis (CRUS) presents a complex forearm deformity, requiring precise osteotomy planning for anatomical restoration. This study proposes an automatic osteotomy preoperative planning method for forearms with CRUS.

Variation in trabecular bone microarchitecture across rhesus macaque (Macaca mulatta) load‐bearing joints

Journal of Anatomy, EarlyView.
Aging of bone density (BV/TV) is regional: Forelimb [left] elements gain bone sporadically (orange) but hind limb elements [right] lose bone globally (blue). Abstract Globally, human population structure is quickly trending older, increasing the prevalence and systemic burden of age‐related skeletal disorders such as osteoporosis.

Tracking dinosaurs in Scotland [PDF]

, 2005
<p>Dinosaurs, the Loch Ness Monster not included, are a rarity in Scotland. Although dinosaurs have been known of in England and elsewhere in the world for over 300 years, it was only in the last 23 years that dinosaurs began to appear in Scotland.

Does ulnar curvature covary with locomotion and substrate use in cercopithecids?

Journal of Anatomy, EarlyView.
This study investigates ulnar curvature in cercopithecids in relation to locomotor behaviors, introducing an analysis of anteroposterior and mediolateral curvature, using geometric morphometric on 167 specimens (23 species). Although the two curvatures distinguish arboreal and terrestrial quadrupeds, their moderate covariation suggests that they ...

Scaling of internal joint distance in the elbow of small‐ to medium‐sized mammals: Implications for range of motion analyses

Journal of Anatomy, EarlyView.
We investigated the internal joint distances (IJDs) of the humero‐ulnar and humero‐radial joint, within a sample of 15 small‐ to medium‐sized mammals and report isometric results. We also found that joint poses had no effect on IJDs and that IJDs scale isometrically within small species.

Soft tissue abnormalities in the congenital limb malformation radial dysplasia (RD): Their clinical impact and treatment significance

Journal of Anatomy, EarlyView.
We review the characteristic changes to the limb soft tissue and neurovascular abnormalities that have been described in the congenital limb birth defect, Radial Dysplasia. These include consistent changes in muscle anatomy or absence of specific muscles, persistent median arteries and absent radial arteries and consistent alterations in neural ...

Hoffmann's two‐toed sloth II: Muscle architectural properties in the thoracic limb of Choloepus (Pilosa: Xenarthra)

Journal of Anatomy, EarlyView.
Two‐toed sloths use their thoracic limbs for more frequent and greater suspensory support than three‐toed sloths and have muscle architectural properties consistent with stability of the pectoral girdle, enhanced flexor force/torque applied at the shoulder and elbow joints, and grip on the support as indicated by their myology. Abstract Two‐toed sloths
