Femoral Neck Fractures in Children: A Review

Indian Journal of Orthopaedics, 2018
Paediatric femoral neck fractures are uncommon injuries and are usually caused by high-energy trauma. Low-energy trauma can result in pathologic neck fractures and stress fractures of the neck, due to repetitive activity.

Automated volumetric and statistical shape assessment of cam-type morphology of the femoral head-neck region from 3D magnetic resonance images [PDF]

arXiv, 2021
Femoroacetabular impingement (FAI) cam morphology is routinely assessed using two-dimensional alpha angles which do not provide specific data on cam size characteristics. The purpose of this study is to implement a novel, automated three-dimensional (3D) pipeline, CamMorph, for segmentation and measurement of cam volume, surface area and height from ...

Brittle fracture of polymer transient networks [PDF]

Journal of Rheology 61(6), 1267-1275, 2017, 2017
We study the fracture of reversible double transient networks, constituted of water suspensions of entangled surfactant wormlike micelles reversibly linked by various amounts of telechelic polymers. We provide a state diagram that delineates the regime of fracture without necking of the filament from the regime where no fracture or break-up has been ...

Primary care access to radiology: Characteristics of trauma patients referred to the emergency department

Journal of Evaluation in Clinical Practice, Volume 29, Issue 1, Page 101-107, February 2023., 2023
Abstract Rationale, Aims and Objectives Low‐urgent Emergency Department (ED) attendances are a known contributing factor to ED crowding. In the Netherlands, general practitioners (GPs) have direct access to radiology facilities during office hours. Patients with radiographically confirmed traumatic injuries are subsequently referred to the ED.

The application of the 150° oblique tangential fluoroscopic view to detect the posterosuperior femoral neck screw in–out–in intraoperatively

Scientific Reports, 2022
This study investigates the application of the 150° tangential fluoroscopic projection as a novel fluoroscopic view to detect the posterosuperior screw in–out–in (IOI) in the cannulated screws fixation of femoral neck fractures.

Percolative Mechanism of Aging in Zirconia-Containing Ceramics for Medical Applications [PDF]

Advanced Materials, Volume 15, Issue 6, March, 2003, Pages 507-511, 2018
Recently, several episodes of fracture of zirconia ceramic femoral heads of total hip prostheses have alarmed the medical and scientific community regarding aging problems in zirconia prostheses. Such fractures cause immediate local tissue reactions, which require urgent medical intervention to prevent further complications.

Ipsilateral Acetabular and Femoral Neck and Shaft Fractures

Case Reports in Orthopedics, 2015
Floating hip injuries and ipsilateral femoral neck and shaft fractures are rare. Additionally, the simultaneous occurrence of these injuries is extremely rare, and only one case report of the simultaneous occurrence of these injuries has been published ...

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

BMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).
