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 ...

The family Carabodidae (Acari, Oribatida) VIII: The genus Machadocepheus (first part) Machadocepheus leoneae sp. n. and Machadocepheus rachii sp. n. from Gabon [PDF]

, 2014
The genus Machadocepheus, being one of the more complex genera of the Carabodidae family, is briefly outlined to demonstrate this complexity. Descriptions of two new species from Gabon, M. leoneae sp. n. and M. rachii sp. n.

Vibratory and conventional impaction of acetabular components into porcine acetabula

Bone & Joint Research
Aims: Sufficient primary implant stability with minimal bone damage is one of the challenges for uncemented implant fixation to prevent periprosthetic fractures and implant loosening.

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)

Journal of Anatomy, EarlyView.
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

An In vitro Simulation Method for the Tribological Assessment of Complete Natural Hip Joints [PDF]

, 2017
The use of hip joint simulators to evaluate the tribological performance of total hip replacements is widely reported in the literature, however, in vitro simulation studies investigating the tribology of the natural hip joint are limited with ...

Development of the abdominal musculature in the chicken embryo

Journal of Anatomy, EarlyView.
In this study, we investigate anatomy, morphogenesis, segmental origin, and fiber formation of the abdominal musculature in the chicken embryo. We show that abdominal muscles arise from somites 24 to 28, and that the segmental identity of individual fibers in the abdominal muscle sheets is maintained.

Correlation between the Acetabular Diameter and Thickness in Thais

Journal of Orthopaedic Surgery, 2002
We conducted a study on dried cadaveric pelvic bones to determine the relation between acetabular diameter and thickness of the acetabular wall. The acetabulum was divided into four quadrants: antero-superior, postero-superior, postero-inferior, and ...

Algorithm of selection of acetabular component of hip joint endoprothesis in patients with femoral head aseptic necrosis.

Medičnì Perspektivi, 2015
The article represents a comparative roent­gen­morphometric analysis of hip joint deformation development in femoral head aseptic necrosis (FHAN) that was done to identify criteria which determine the selection of the acetabular component of the total ...

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.

A new mini-navigation tool allows accurate component placement during anterior total hip arthroplasty. [PDF]

, 2018
Introduction: Computer-assisted navigation systems have been explored in total hip arthroplasty (THA) to improve component positioning. While these systems traditionally rely on anterior pelvic plane registration, variances in soft tissue thickness ...
