ANTEROLATERAL APPROACHES FOR PROXIMAL HUMERAL OSTEOSYNTHESIS: A SYSTEMATIC REVIEW [PDF]

Acta Ortopédica Brasileira, 2019
Objective: Anterolateral approaches for proximal humerus osteosynthesis have great advantages because they allow direct exposure of the lateral aspect of the humerus without the muscular retraction seen in the deltopectoral approach.

Segmentation of cortical bone, trabecular bone, and medullary pores from micro‐CT images using 2D and 3D deep learning models

The Anatomical Record, EarlyView.
Abstract Computed tomography (CT) enables rapid imaging of large‐scale studies of bone, but those datasets typically require manual segmentation, which is time‐consuming and prone to error. Convolutional neural networks (CNNs) offer an automated solution, achieving superior performance on image data.

Review of the anatomical basis for predicting plutonium alpha particle radiation induced osteogenic cancers

The Anatomical Record, EarlyView.
Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

A rare procedure of total humerus allograft for osteosarcoma

Journal of Orthopaedic Reports, 2022
Background: One of the most common sites for primary sarcoma is the proximal humerus. Despite several methods of reconstruction, an ideal method for reconstruction after proximal humeral resection is controversial.

Silesaurid (Archosauria: Dinosauriformes) remains from the base of the Dockum Group (Late Triassic: Otischalkian) of Texas provide new insights to the North American record of dinosauriforms

The Anatomical Record, EarlyView.
Abstract Silesaurids (Archosauria: Dinosauriformes) are found in Middle to Upper Triassic deposits across Pangea, but few stratigraphic sections record the evolution of the group in one geographic area over millions of years. Here, we describe silesaurid remains from the oldest of the Upper Triassic stratigraphic sequence from the base of the Dockum ...

“90/90” Plating of proximal humerus fracture—a technical note

Journal of Orthopaedic Surgery and Research, 2019
Introduction While locking plates have markedly improved fixation of proximal humerus fractures, a cohort of fractures remains difficult to treat. This cohort has been identified as fractures with marked medial comminution and varus deformity.

Cement augmentation of the proximal humerus internal locking system in elderly patients: a multicenter randomized controlled trial

Archives of Orthopaedic and Trauma Surgery, 2019
IntroductionCement augmentation of the proximal humerus internal locking system (PHILOS) screws might reduce complication rates in osteoporotic bones.

A proximodistal gradient in bone structure and mechanics in the wings of Seba's short‐tailed bat, Carollia perspicillata

The Anatomical Record, EarlyView.
Abstract Bats possess the remarkable ability to fly, and with this, distinctive wing bone properties. We investigated the structural, mechanical, and compositional properties of the humerus, radius, metacarpals, and proximal and middle phalanges of Carollia perspicillata, an approximately 15 g fruit‐eating bat native to the Neotropics.

Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

The Anatomical Record, EarlyView.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

Bilateral traumatic proximal humerus fractures managed by open reduction and internal fixation with locked plates

Chinese Journal of Traumatology, 2013
【Abstract】Fractures of the proximal humerus are uncommon in young patients. Although bilateral fracture of proximal humerus itself is rare, association with epilepsy and electrocution is frequent. Only one case of traumatic bilateral proximal humerus
