Comparing biomechanical strength of unicortical locking plate versus bicortical compression plate for transverse midshaft metacarpal fracture

Journal of Orthopaedic Surgery, 2018
Purpose: Metacarpal bone fractures constitute 10% of all fractures. Unstable metacarpal fractures require surgical intervention, which poses danger to flexor tendon either due to bicortical drilling or construct of the implant.

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.

Microanatomical features of bovids long bones: What are the effects of mass and habitat?

Journal of Anatomy, EarlyView.
This study provides the first qualitative and quantitative exploration of inter‐bones and interspecific variations in the microanatomy of long bones in bovids in response to significant changes in body mass and habitat. Abstract Bovids are a valuable group for studying limb long bone adaptations due to differences in size and the environment that the ...

Preexisting lesions associated with complete diaphyseal fractures of the third metacarpal bone in 12 Thoroughbred racehorses

, 2017
We characterized features of complete diaphyseal fractures of third metacarpal bones in Thoroughbred racehorses. Given that stress fractures are known to occur in the third metacarpal bone, an additional aim was to determine if complete fractures are ...

Allometric patterns in Rhamphorhynchus muensteri and their role in the paleoecology, life habits, and taxonomic framework of pterosaurs

Journal of Anatomy, EarlyView.
The Graphical Abstract ilustrates the different allometric pattern within different Pterosauria groups, highlighting how the allometry influences the flight and habits of Pterosauria. Abstract Pterosaurs were the first vertebrates to achieve powered flight, a result of various unique anatomical adaptations, and significant morphological diversity ...

Scratching beneath the surface: Quantification of muscle architecture and myosin heavy chain content in the forelimbs of black‐tailed prairie dogs (Cynomys, Rodentia)

Journal of Anatomy, EarlyView.
Black‐tailed prairie dogs are highly social ground squirrels that excavate communal burrow systems, most often in medium‐textured soils. Their forelimbs demonstrate morphofunctional trade‐offs for scratch‐digging and terrestrial ecology, including well‐developed and fast‐contracting proximal musculature with large mechanical advantage paired with ...

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

Customized Metal 3D Printed Total Wrist Prosthesis in the Treatment of Severely Destroyed Wrist: Design Rationale and Clinical Applications

Orthopaedic Surgery, Volume 17, Issue 5, Page 1536-1546, May 2025.
Four patients with severe wrist destruction from various causes were treated with customized 3D‐printed prostheses. In addition to the specific articular surface matching their original radiocarpal joint, two innovative proximal component designs were created to address different bone defects.
