Purpose: To analyse the characteristics of patients who underwent surgery for fractures of the upper thoracic spine (T1-T6) in our institution. The thoracic spine is supported by the rib cage and associated ligaments; therefore, displacement and fracture of the upper thoracic spine in healthy young adults require a great force. The relatively narrow spinal canal around the spinal cord in this area could result in severe neurological deficit should fractures occur.
Methods: The treatment course of 32 patients (26 men and 6 women) who underwent surgery for fractures of the upper thoracic spine between February 1995 and March 2001 was retrospectively reviewed. Parameters of injuries and treatment methods were evaluated.
Results: Of the 32 patients, 29 were injured in traffic accidents (15 motorcycle and 14 vehicle), 2 in falls, and one by a heavy door falling on his back. 29 patients had spinal fractures at more than one level. 23 patients had complete, 7 had incomplete, and 2 had no neurological deficit. 30 patients required multiple modalities of radiological imaging (in addition to plain radiography) for diagnosis. 20 patients sustained other injuries apart from spinal fractures, 15 of them had associated chest injuries.
Conclusion: High-velocity fractures of the upper thoracic spine are injuries with devastating consequences, and can result in severe neurological deficit and concomitant injuries. These patients are best treated by a multidisciplinary approach.

Morphometric and Morphological Study of Thoracic and Lumbar Intervertebral Discs in Guinea Pigs (Cavia porcellus).

This study investigates the gross morphological and morphometric characteristics of thoracic and lumbar intervertebral discs (IVDs) in guinea pigs, utilising micro-CT imaging and anatomical dissection. The findings reveal 13 thoracic and six lumbar IVDs were identified, with thoracic discs transitioning from rounded forms at T1-T3 to triangular and heart-shaped structures at T4-T13, while lumbar IVDs exhibited a consistently flattened heart shape. Morphometric analysis revealed statistically significant differences, with lumbar IVDs being larger in lateral and dorsoventral width, disc area, annulus fibrosus (AF) area and nucleus pulposus (NP) area, and ventral height compared to thoracic discs.

Unlabelled: Tuberculosis (TB) can affect any organ, and at times more than one organ in any sequence, in which case it is referred to as disseminated tuberculosis (DTB). We report a patient who presented primarily for psychiatric symptoms of three months' duration, which later turned out to be a case of DTB involving the central nervous system as well as the spine and lungs.
Case Presentation: An elderly lady with subacute onset and worsening behavioural changes of three months' duration was referred for exclusion of organic brain disease.
Characteristics of e-scooter and bicycle injuries at a university hospital in a large German city - a one-year analysis.

Background: The increasing adoption of individual urban mobility in European cities is contributing to a rise in the number of bicycle and e-scooter users. Consequently, a corresponding increase in accidents, along with an additional burden on emergency departments, is anticipated, particularly in metropolitan areas. The objective of this prospective cross-sectional study was to gather detailed information regarding the patient demographics, accident mechanisms, and injury patterns of e-scooter riders in comparison to cyclists.

Objective: The purpose of this study was to evaluate the risk factors for loss of intraoperative correction, as measured by lumbar lordosis (LL), with an emphasis on rod characteristics.
Methods: A retrospective study identified patients at least 50 years of age who underwent instrumented fusion with an upper instrumented vertebrae (UIV) in the upper thoracic spine (T1-T6) or thoracolumbar junction (T10-L2) to the pelvis. Inclusion criteria included intraoperative x-rays that allowed for LL measurement, postop standing x-rays, and a minimum follow up of 24 months with the original rods still in place.
Objective: To investigate the value of routine T2-weighted magnetic resonance imaging (MRI) and contrast-enhanced magnetic resonance angiography (CE-MRA) sequences in locating the fistula level of spinal arteriovenous fistula (SAVF).
Methods: Retrospectively analyzed the radiological findings of patients with SAVF diagnosed by surgery from May 2018 to September 2024. All patients completed spinal CE-MRA and routine T2-weighted MRI.
