Proximal Humerus Open Fracture in Pediatrics: A Case Report and Literature Review

Journal of Orthopedic and Spine Trauma
Background: Proximal humerus fracture (PHF) in pediatrics is managed with different options: nonoperative or operative. However, proximal humerus open fractures are sparse in the literature. Case Report: We present a 9-year-old boy who presented

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.

A clinical case of multifocal fracture combining fracture of the head and diaphysis of the humerus

Вестник медицинского института «Реавиз»: Реабилитация, врач и здоровье
Relevance. According to statistical data, multifocal fractures of the humerus are quite rare, accounting for approximately 6% of all skeletal bone fractures.

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.

Biomechanical properties of a novel fixation system for intra-articular distal humerus fractures: a finite element analysis

Journal of Orthopaedic Surgery and Research, 2021
Background The traditional strategy for fixing intra-articular distal humerus fractures is double plating placed in an orthogonal configuration, based on posterior approach.

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.

A study of nutrient foramina in dry adult humeri of South Indian subjects

National Journal of Clinical Anatomy, 2012
Background: Vascular insults to the humerus either during fracture dislocation or during surgical correction of fracture may result in delayed healing or non-union of fracture. It is worth to find the number and size of nutrient foramina.

Proximal humerus fractures and shoulder dislocations: Prevalence of concomitant rotator cuff tear

Journal of Orthopaedics, Trauma and Rehabilitation, 2023
Background: Proximal humerus fractures and shoulder dislocations are relatively common. However, an associated rotator cuff tear is often missed with these injuries.

Reverse shoulder arthroplasty for proximal humerus fracture using a dedicated stem: radiological outcomes at a minimum 2 years of follow-up—case series

Journal of Orthopaedic Surgery and Research, 2015
BackgroundComplex proximal humeral fractures are very difficult to treat particularly in patients older than 65 years with an osteoporotic bone and tuberosities compromised.

The tiger salamander as a promising alternative model organism to the axolotl for fracture healing and regenerative biology research

The Anatomical Record, EarlyView.
Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.
