An Internal Arc Fixation Channel and Automatic Planning Algorithm for Pelvic Fracture [PDF]
arXiv, 2021 Fixating fractured pelvis fragments with the sacroiliac screw is a common treatment for unstable pelvis fracture. Due to the complex shape of the pelvis, sometimes a suitable straight screw fixation channel cannot be found using traditional methods, which increases the difficulty of pelvic fracture fixation. Therefore, there is an urgent need to find a

Common low back pain hiding tuberculous sacroiliitis
Clinical Case Reports, 2022 The sacroiliac joint is rarely affected by tuberculosis. Only few cases have been reported. Consequently, the diagnosis is often delayed. This case report highlights the importance of continued awareness for early detection and treatment of a tuberculous

Automatic detection and diagnosis of sacroiliitis in CT scans as incidental findings [PDF]
, 2019 Early diagnosis of sacroiliitis may lead to preventive treatment which can significantly improve the patient's quality of life in the long run. Oftentimes, a CT scan of the lower back or abdomen is acquired for suspected back pain. However, since the differences between a healthy and an inflamed sacroiliac joint in the early stages are subtle, the ...

Theoretical Limits of Joint Detection and Estimation for Radar Target [PDF]
arXiv, 2022 This paper proposes a joint detection and estimation (JDE) scheme based on mutual information for the radar work, whose goal is to choose the true one between target existent and target absence, and to estimate the unknown distance parameter when the target is existent.

Simultaneous topology and fastener layout optimization of assemblies considering joint failure [PDF]
, 2020 This paper provides a method for the simultaneous topology optimization of parts and their corresponding joint locations in an assembly. Therein, the joint locations are not discrete and predefined, but continuously movable. The underlying coupling equations allow for connecting dissimilar meshes and avoid the need for remeshing when joint locations ...
