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.

Association of schizophrenia with fracture‐related femoral neck displacement: A cross‐sectional retrospective study

PCN Reports
Aim Fracture‐related femoral neck displacement is more likely in patients with schizophrenia because of delayed diagnosis, as these patients frequently have less severe fracture‐associated subjective symptoms.

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.

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).

Three‐dimensional assessment of subchondral arc and hip joint coverage angles in the asymptomatic young adult hip

Clinical Anatomy, EarlyView.
Abstract The primary objective of this study was to develop a custom algorithm to assess three‐dimensional (3D) acetabular coverage of the femoral head based on surface models generated from computed tomography (CT) imaging. The secondary objective was to apply this algorithm to asymptomatic young adult hip joints to assess the regional 3D acetabular ...

Successful treatment for bilateral femoral neck insufficiency fractures: a rare lesion case report and an updated review of the literature

BMC Musculoskeletal Disorders, 2020
Background The incidence of insufficiency fracture (IF) at femoral neck is low, accounting for about 5% of all insufficiency fractures, and IF at bilateral femoral neck is less common with more occurrence in athlete or serviceman.
