Hoffmann's two‐toed sloth I: Complete myology in the thoracic limb of Choloepus (Pilosa: Xenarthra)

Journal of Anatomy, EarlyView.
Two‐toed sloths use their thoracic limbs for more frequent and prolonged suspensory support than three‐toed sloths and accordingly demonstrate myological traits consistent with stability of the pectoral girdle, enhanced flexor force/torque applied at the elbow joint, and grip on the support.

Open Dislocation of the Scaphoid With an Associated Hamate Fracture and Fourth Metacarpal Fracture

Journal of Hand Surgery Global Online
Scaphoid dislocation represents a rare injury with only a few case reports and limited case series reported in the literature. The majority of scaphoid dislocations result from a high-energy trauma causing hyperextension and ulnar deviation of the wrist.

Pulsed Electromagnetic Fields in the treatment of fresh scaphoid fractures. A multicenter, prospective, double blind, placebo controlled, randomized trial

BMC Musculoskeletal Disorders, 2011
Background The scaphoid bone is the most commonly fractured of the carpal bones. In the Netherlands 90% of all carpal fractures is a fracture of the scaphoid bone.

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 ...

Virtual brain endocasts of the palaeanodont Metacheiromys marshi and the neurosensory evolution of early Pholidotamorpha

Journal of Anatomy, EarlyView.
We describe the endocranial anatomy of Metacheiromys marshi. Decrease in olfaction and eye movement control occurred through time in Pholidotamorpha and is likely linked to fossorial adaptations. The development of the orbital gyrus might be related to the evolution of myrmecophagy and the emergence of a protrusile tongue in early Pholidotamorpha ...

How do forelimb long bones adapt in rhinoceroses? An in‐depth examination of their microanatomy

Journal of Anatomy, EarlyView.
Here, we study the bone structure in the forelimb long bones of the five extant species of rhinoceroses. By combining traditional description of virtual sections made on the bones (A) with in‐depth cartographies of the variation of bone compactness and anisotropy (B), we show how bone tissue can adapt to extreme forces and constraints in the second ...

Treatment of scaphoid waist nonunion with iliac crest bone graft and double Kirschner wire fixation: An observational clinical study

Journal of Orthopaedic Reports
Background: Scaphoid fracture nonunion may be considered a serious problem if not treated properly. Nonunion can lead to resorption, loss of bone, and deformity.

Morphofunctional effects of captivity on the microanatomy of the talus bone in a wild ungulate (Sus scrofa)

Journal of Anatomy, EarlyView.
Our study explores the plastic changes induced by captivity on the microanatomy of the talus of wild boars, revealing denser bone with tighter trabecular networks but a lower relative maximum thickness of compact bone. These plastic adaptations can serve to detect early processes of domestication in the archaeological record.

Growing together: Developmental integration and modularity in the human talus–calcaneus complex

Journal of Anatomy, EarlyView.
This study investigates morphological integration and trabecular bone development in the human talus–calcaneus complex during postnatal ontogeny. The two bones exhibit strong integration throughout development, with differing bone volume fraction trajectories presumably reflecting their distinct functional roles during bipedal gait acquisition ...
