CONCLUSION: The diagnosis of intrathoracic textiloma remains rare and its late presentation is non specific. Radiological imaging with a CT-scan and/or MRI could lead to the diagnosis. Surgery remains the reference treatment for the diagnosis and cure of intrathoracic textiloma with pathological examination, essential for confirmation. A means of prevention has to be developed because swab count is not totally reliable. PMID: 30446182 [PubMed - as supplied by publisher]

ConclusionThe proposed digital workflow allows to predict in an accurate and truly three ‐dimensional way the final position of roots, when an initial CBCT is available, without the need of an extra X‐ray examination for the patient at the end of treatment. The limitation of the exposure to mid‐ and post‐ treatment x‐rays is in accordance with the ALARA (As Low As Reasonably A chievable) principle and it is even more relevant in growing patients.This article is protected by copyright.

This study aimed to evaluate the intra- and interobserver agreement for fracture classifications of the glenoid, using either plain radiographs, computed tomography (CT) scans. The study was retrospective, using images with a variety of fracture types. Six observers classified the fracture patterns. Classifications of Ideberg, OTAAO, Mayo and Euler/Ruedi were used. Agreement was determined using kappa coefficients. Currently used glenoid fracture classification systems have a fair to moderate intraobserver reliability. Combining plain radiographs and CT scans led to a better observer agreement. For interoberserver reliabil...

Authors: Mišič J, Popović P, Hribernik M, Starc A, Dahmane R Abstract In the liver, there are many vascular variants, which are important in liver surgery, the presence of accessory right hepatic veins (aRHVs) in particular. Th eir frequency, number and diameter vary considerably. Detailed imaging diagnostics with computed tomography (CT) should be undertaken before surgery. Th e aim of our study was to examine the characteristics of aRHVs and their demographic correlations. Th e study included data on 188 patients that underwent CT examination of the abdomen with contrast media, 103 men (54.8%) men and 85...

LuoAbstractPlate impact experiments are conducted on a rolled titanium alloy Ti-6Al-4V to investigate the effects of structural anisotropy on dynamic deformation and damage, with the loading axis being parallel to the normal direction or transverse direction, referred to as LA∥ND and LA∥TD, respectively. Free-surface velocity histories are measured to evaluate the mechanical properties; the Hugoniot elastic limits for the LA∥ND and LA∥TD loading are 3.38 GPa and 3...

The objective of this study was to evaluate screw choices for three-dimensional (3D) digital pre-operative planning of osteosynthesis of distal radius fractures and to compare with the screw choices for the conventional method. METHODS: Distal radius fracture patients who underwent osteosynthesis using volar locking plates were evaluated. Thirty wrists in the plan group utilized 3D preoperative planning, and nineteen wrists in the control group utilized conventional preoperative assessment. In the plan group, the 3D preoperative planning was performed prior to surgery. The reduction was simulated with 3D image, and th...

This study aims to evaluate the accuracy of patient-specific computed tomography (CT)-based rapid prototype drill guide templates for the CBT technique. CT scanning was performed in 7 cadaveric thoracolumbar spines, and a 3-dimensional reconstruction model was generated. By using computer software, we constructed drill templates that fit onto the posterior surface of thoracolumbar vertebrae with drill guides to match the CBT. In total, 80 guide templates from T11 to L5 were created from the computer models by using rapid prototyping. The drill templates were used to guide the drilling of CBT screws without any fluoroscopic...
