Dilated MMA sign in cDAVF and other arterial feeders on 3D TOF MRA

A cranial dural fistula is among the various causes of pulsatile tinnitus, which can cause significant mortality and morbidity, is a cranial dural arteriovenous fistula. " This paper was intended to determine the diagnostic accuracy of the dilated middle meningeal artery by three-dimensional time-of-flight magnetic resonance angiography in cranial dural arteriovenous fistula, as well as other feeders that may help with the identification of these lesions. All patients with cranial dural arteriovenous fistula treated in a joint tertiary referral center between 2007 and 2020 were included in both magnetic resonance angiography and digital subtraction angiography results. Magnetic resonance angiography was assessed on the middle meningeal artery and other feeders obtained from digital subtraction angiography. "The dilated middle meningeal artery sign can help identify a cranial dural arteriovenous fistula," the author states.

3D PRINTING TECHNIQUE FOR PATIENT-SPECIFIC INSTRUMENTATION IN TOTAL KNEE ARTHROPLASTY

"The aim of the study was to evaluate clinical and radiological consequences of knee arthroplasty using patient-specific websites that are used for positioning resection blocks. " With the use of patient specific maps for resection blocks positioning, the authors reviewed the treatment outcomes of four patients during the period from 2015 to 2016 when they underwent complete knee arthroplasty for posttraumatic gonarthroplasty in the III-IV stage. All patients' initial signs of mobility in the knee joint were limited. Results were found in accordance with FLFS roentgenography, all patients had a varus deformity of the lower leg with an average value of 15. 0u00b112. 3. u00b0. In both patients, the authors noted a significant rise in joint mobility and a pain syndrome reduction. In the following situations: inflammatory process or deformation of the femoral joint in patient's history; when the use of intramedullary charts is problematic; severe mobility restrictions in the knee joint; or the use of a common set of instruments creates significant technological challenges.

Effects of 3D Imaging on Surgical Tactics in Primary and Revision Hip Arthroplasty

The aim of the research was to determine the 3D imaging capabilities of bone tissue repair and optimization of hip osteoarthroplasty. Materials and Methods The 3D model in 80% of cases did not change the surgical tactics established in the preoperative planning using pelvic radiographs; in 20% of cases, the use of 3D imaging revealed new circumstances and changed the surgical approaches. Conclusion. It is also recommended to perform 3D imaging in primary hip arthroplasty in patients with post-traumatic deformity, which includes a missing joint of acetabulum bottom or 2 to 3 degree osteopenia. In the case of revision arthroplasty, 3D visualization is suggested in acetabulum Paprosky IIIA, IIIB, pelvic discontinuity.
