Medullary radius as a major contributor to variance in the proximal femur: Insights from statistical shape modeling

Journal of Anatomy, EarlyView.
Workflow from CT to PCA‐based shape modeling of the proximal femoral canal (n = 763). Feature maps (size, roundness, torsion, flare, curvature) reveal sex‐ and age‐dependent patterns; three PCs capture ≈68% of variance and summarize dominant anatomical changes. Insights inform implant sizing and design envelopes in cementless THA.

A report of radiographic manifestations of 32 patients with Histiocytosis X

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2001
Objective: Histiocytosis-X (H-X) is more common in children who are under 12 years. It involves different organs such as bone, lung, liver, spleen and skin.

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 ...

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.

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 ...

Induced Biochemical osteoporosis: Effects of 1-month calcium–deprived diet on rat bone remodelling with/without contemporary administration of PTH(1-34) [PDF]

, 2013
It is known that rats fed calcium-deprived diet develop osteoporosis due to en-hanced bone resorption secondary to parathyroid overactivity resulting from nutritional hypocalcemia.

Postcranial anatomy of the Miocene hippopotamoids of Toros‐Menalla, Chad

Journal of Anatomy, EarlyView.
We establish a framework for the identification of postcranial remains in hippopotamoids by describing and comparing for the first time two late Miocene hippopotamoids from Toros‐Menalla, Chad (Hexaprotodon garyam, an early hippopotamid, and Libycosaurus bahri, the last African anthracothere) with the common hippopotamus.
