[Transosseous lacerations in the ankylosed cervical spine].

Transosseous lacerations represent a particular type of discoligamentous injury of the cervical spine and occur in ankylosing diseases of the spine, with ankylosing spondylitis and diffuse idiopathic skeletal hyperostosis (DISH) being the primary entities. The altered biomechanics of the spine due to the underlying disease pose special challenges in the diagnostics and treatment. Even low-energy trauma can cause severe injuries of the cervical spine, which are often difficult to accurately diagnose due to the difficult assessability of the conventional projection radiography used in the primary diagnostics.

Two-screw osteosynthesis is biomechanically superior to single-screw osteosynthesis for type II odontoid fractures.

The data on the use of a one- or two-screw technique (1S, 2S) for ventral osteosynthesis of type II dens fractures are contradictory. The aim was to design an apparatus to mimic the physiological conditions and test stability with 1S, 2S, and a headless compression screw (HCS) for osteosynthesis of artificially created type II odontoid fractures. The apparatus was mounted on a Zwick materials testing machine.

Interleukin-6 as a critical inflammatory marker for early diagnosis of surgical site infection after spine surgery.

Purpose: Early diagnosis of surgical site infections (SSIs) could prevent surgical revision. Inflammatory markers (IMs), such as procalcitonin (PCT), interleukin-6 (IL-6), and tumor necrosis factor α (TNF-α), seem more accurate in diagnosing SSI than C-reactive protein (CRP) and white blood cell (WBC) count. The aim was to compare the predictive values of CRP, WBC count, PCT, IL-6, and TNF-α in SSI detection.

Effect of a Contrast Agent on Bone Mineral Density Measurement in the Spine and Hip Using QCT-Conversion Factor Recommendation.

Background: Osteoporosis causes an increased fracture risk. Clinically, osteoporosis is diagnosed late, usually after the first fracture occurs. This emphasizes the need for an early diagnosis of osteoporosis.

Combination of vertebral bone quality scores from different magnetic resonance imaging sequences improves prognostic value for the estimation of osteoporosis.

Background Context: Recent findings revealed a correlation between vertebral bone quality based on T1-weighted (VBQ) magnetic resonance imaging (MRI) and volumetric bone mass density (vBMD) measured using quantitative computerized tomography. The coherence of VBQ for other MRI sequences, such as T2 or short tau inversion recovery (STIR), has not been examined. The combination of different VBQs has not been studied.

Physiological Offset Parameters of the Adult Shoulder Joint-A MRI Study of 800 Patients.

Background: Humeral offset (HO) and glenoidal offset (GO) are important morphological parameters in diagnostics and therapy for shoulder pathologies. However, physiological reference values have not yet been sufficiently determined. The aim of the present study was to establish physiological reference values for shoulder offset parameters (SOPs).

Morphological Analysis of the Tibial Slope in 720 Adult Knee Joints.

Background: The tibial slope (TS) defines the posterior inclination of the tibial plateau (TP). The “individual physiological” TS plays a crucial role in knee-joint stability and should be taken into account in knee-joint surgery. The aim of this study was to analyse the specific morphology of the TS for the medial (med) and lateral (lat) TP in relation to patient characteristics and the measurement method.
