PMMA can significantly enhance pediclescrew stability in osteoporosis and severe osteoporosis.
2
Only studies of water-based endoscopic TLIF with pediclescrew fixation were included.
3
The accuracy of thoracic pediclescrew placement is critical to the spinal surgery.
4
The primary endpoint was to compare pediclescrew accuracy between the 2 groups.
5
The accuracy of pediclescrew placement was later reviewed and recorded by independent observers.
Usage of pedicle screws in inglês
1
It was possible to postoperatively compare the position classifications of 406 pediclescrews.
2
The potential use of drill templates to place lumbar pediclescrews is promising.
3
Fluoroscopy was used only once after all the pediclescrews had been inserted.
4
The thoracic pediclescrews were inserted with the help of the navigation module.
5
The main problem of the procedure is the false positioning of the pediclescrews.
6
In the comparison group, 211 pediclescrews were placed.
7
Thoracic and lumbar cortical bone trajectory pediclescrews have been described in adult spine surgery.
8
Seventy-six cortical bone trajectory pediclescrews were placed.
9
A total of 133 pediclescrews were placed.
10
Study design: A biomechanical study in porcine spines of the construct stiffness effects of segmental pediclescrews.
11
The exact determination of pediclescrews has up to now only been possible through postoperative computed tomography.
12
The positions of the pediclescrews were determined and compared in the axial reconstructions of both procedures.
13
Based on the anatomic measurements, it may be reasonable to consider thoracic pediclescrews in preadolescent idiopathic scoliosis.
14
Initial insertional torque values were significantly greater in pediclescrews placed with washers compared with screws placed without washers.
15
In the cadaveric experiment, 36 pediclescrews were inserted and no pedicle perforation was observed by postoperative CT scan.
16
Interpretation: Posterior pediclescrews demonstrated the best mechanical stability of allospacer failure-subsidence and the lowest risk of screw loosening.
