Femur fractures and hemorrhagic shock: Implications for point of injury treatment.

Background: Femur shaft fractures (FSF) are perceived as potentially life-threatening injuries due to significant blood loss. However, these injuries are rarely the sole cause of hemorrhagic shock. Clinical practice guidelines for the prehospital management of FSF are inconsistent, especially concerning the use and timing of traction splinting which is postulated to reduce bleeding.

Mapping of magnetic resonance imaging's transverse relaxation time at low signal-to-noise ratio using Bloch simulations and principal component analysis image denoising.

High-resolution mapping of magnetic resonance imaging (MRI)'s transverse relaxation time (T ) can benefit many clinical applications by offering improved anatomic details, enhancing the ability to probe tissues' microarchitecture, and facilitating the identification of early pathology. Increasing spatial resolutions, however, decreases data's signal-to-noise ratio (SNR), particularly at clinical scan times. This impairs imaging quality, and the accuracy of subsequent radiological interpretation.

T2 Mapping Values in Postmeniscectomy Knee Articular Cartilage after Running: Early Signs of Osteoarthritis?

Loading on the joints during running may have a deleterious effect on post-partial meniscectomy knee cartilage, leading to osteoarthritis. Utilizing T2-mapping measurements before and after running may enable the observation of changes in the articular cartilage of the postmeniscectomy knees compared with healthy knees. After medial partial meniscectomy, 12 volunteers underwent magnetic resonance imaging (MRI) of the both knees, before and immediately after 30 minutes of running.

Gas forming infection of the spine: a systematic and narrative review.

Purpose: Gas forming infection (GFI) of the spine is a rapidly progressive and potentially life-threatening infection. It can be a consequence of aetiologies such as Emphysematous Osteomyelitis (EOM), Necrotizing Fasciitis (NF), and Gas-containing Spinal Epidural Abscess (Gas-containing SEA). This review aims to summarize the characteristics of these subtypes of GFI, describing their aetiology, diagnosis, management, and prognosis.

Delayed Penetration of the Thoracic Aorta by Pedicle Screws: A Case Report of Screws Left As-Is.

Study Design: A case report.

Objective: Presentation of a patient diagnosed with perforation of the aorta by pedicle screws at levels T6 and T9 2 years after spinal fusion, who was advised no intervention. Review of other reported cases that did not undergo excision of the penetrating screws.
