BackgroundThe purpose of this study was to investigate the accuracy of perforation detection with multiplanar reconstructions using a mobile 3D image intensifier.MethodsIn 12 paired human humeri, K-wires perforating the subchondral bone and placed just below the cartilage level were directed toward five specific regions in the humeral head. Image acquisition was initiated by a fluoroscopy scan. Within a range of 90°, 45° external rotation (ER) and 45° internal rotation (IR). The number and… 
Optimal viewing angles of intraoperative fluoroscopy for detecting screw penetration in proximal humeral fractures: a cadaveric study
A 0°–10° axillary view with 30° arm abduction combined with two horizontal angles in the range of − 30° to −‬10° and 10° to 35° for routine fluoroscopy during surgery will be helpful in avoiding primary screw penetration.

This survey aims to highlight the importance of deep learning techniques in chest disease diagnosis and broadly analyze different DL techniques and recognize some of the important research challenges that mostly affect deep neural networks for investigating various chest diseases.


[Multiplanar reconstruction with mobile 3D image intensifier. Surgical treatment of proximal humerus fractures].
Intraoperative 3D imaging with mobile image intensifier enables an accurate analysis of fracture morphology and a quasi real time preoperative planning, evaluation of reduction and implant position with immediate operative relevance can be realized.
How to Use Fluoroscopic Imaging to Prevent Intraarticular Screw Perforation During Locked Plating of Proximal Humerus Fractures: A Cadaveric Study
The sensitivity and specificity of the fluoroscopic images used to evaluate whether a screw tip has perforated into the glenohumeral joint were determined and screws that are intraarticular may appear to be completely located within the bone of the proximal humerus on some C-arm images.
[The clinical use of the ISO-C(3D) imaging system in calcaneus fracture surgery].
Compared in a prospective study including 82 patients treated with ORIF of an intraarticular calcaneus fracture the quality of fluoroscopy, intraoperatively Iso-C(3D) and postoperative CT-scans is compared, it is suggested that intraoperative 3D I so-C-3D imaging provides a high diagnostic reliability.
Evaluation of 2D and 3D navigation for iliosacral screw fixation
3D image guidance for transiliosacral screw fixation enabled more accurate screw placement in S1 and S2 vertebrae and was recommended for older patients; however, radiation exposure in 3D-navigation was excessive; thus, it is recommended avoiding 3D -navigation in young patients.
Intraoperative 3D imaging in calcaneal fracture care-clinical implications and decision making.
Intraoperative three- dimensional visualization with the ISO-C-3D provides important information in the operative treatment of calcaneal fractures which cannot always be obtained from plain films or standard fluoroscopy alone.
Lessons learned from treating patients with unstable multifragmentary fractures of the proximal humerus by minimal invasive plate osteosynthesis
The results might support the use of MIPO for treating unstable multi fragmentary fractures of proximal humerus such as three- or four-part fractures to decrease osteonecrosis of humeral head.
Bone quality measured by the radiogrammetric parameter “cortical index” and reoperations after locking plate osteosynthesis in patients sustaining proximal humerus fractures
The risk for reoperation is independent of the CI even though the CI may be a predictor for proximal humerus fracture, and younger patients should be aware that surgical treatment of proximal Humerus fractures might be a two-stage surgery.
