Limb-Bone Scaling Indicates Diverse Stance and Gait in Quadrupedal Ornithischian Dinosaurs [PDF]

open access: yes, 2012
Background The most primitive ornithischian dinosaurs were small bipeds, but quadrupedality evolved three times independently in the clade. The transition to quadrupedality from bipedal ancestors is rare in the history of terrestrial vertebrate ...

New ophthalmosaurid ichthyosaurs from the European lower cretaceous demonstrate extensive ichthyosaur survival across the Jurassic–Cretaceous boundary [PDF]

open access: yes, 2012
Background Ichthyosauria is a diverse clade of marine amniotes that spanned most of the Mesozoic. Until recently, most authors interpreted the fossil record as showing that three major extinction events affected this group during its history: one ...

Late Presentation of Paediatric Pink Pulseless Supracondylar Fracture of Humerus: A Case Report [PDF]

open access: yesMalaysian Orthopaedic Journal, 2019
Supracondylar humeral fracture is the most common elbow injury in children. It may be associated with a vascular injury in nearly 20% of the cases with a pink pulseless limb.

A Comparative Study on Closed Reduction vs. Open Reduction Techniques in the Surgical Treatment of Rotated Lateral Condyle Fractures of the Distal Humerus in Children

open access: yesFrontiers in Pediatrics, 2022
ObjectiveThe best approach between closed reduction and open reduction in the treatment of total displaced and rotated LCFs is still being debated. This study aimed to comparatively evaluate the clinical outcomes and complications of closed reduction vs.

Management of supracondylar/intercondylar distal humerus fractures using triceps-reflecting anconeus pedicle approach

open access: yesJournal of Orthopedics, Traumatology and Rehabilitation, 2019
Introduction: Chevron olecranon osteotomies are commonly used for intra-articular distal humerus fractures but are often associated with complications such as prominence of hardware, displacement, and nonunion of osteotomy.

A motion-decomposition approach to address gimbal lock in the 3-cylinder open chain mechanism description of a joint coordinate system at the glenohumeral joint [PDF]

open access: yes, 2010
In this study, the standard-sequence properties of a joint coordinate system were implemented for the glenohumeral joint by the use of a set of instantaneous geometrical planes.
