Sentence examples for cup orientation from inspiring English sources
This study was designed to examine the combined effects of acetabular cup orientation and stiffness and on pelvic osseous loading.
Finally, we demonstrate a computational method which provides corrected version and abduction angles to achieve the desired cup orientation, given that the actual measurement errors are known.
This study is intended to test the effect of patient׳s individual geometry of musculoskeletal system, acetabular cup orientation, and radius of femoral head on wear.
Acetabular cup orientation has been shown to influence dislocation, impingement, edge loading, contact stress, and polyethylene wear in total hip arthroplasty.
This work presents a complete mathematical formulation for the analysis of the inaccuracies related to the anterior pelvic plane axes (APPA) definition and their effect on final cup orientation.
We also present a sensitivity analysis of the results by introducing differential changes between sequential coordinate frames, which simulates the errors in the APPA and their effect on cup orientation.
Although cup orientation is affected by a change in pelvic tilt after surgery, it has been unclear whether surgeons can prevent impingement and edge-loading by proper positioning by taking into account any change in pelvic alignment associated with alteration of hip range of motion.
TAL-guided cup orientation was influenced by pelvic sagittal tilt.
With the help of a three-dimensional computer model of the hip, we then systematically analyzed the effects of FT on femoral antetorsion and its influence on calculations for a ROM maximized and impingement-free compliant stem/cup orientation.
This so called "zone-of-compliance" contains a combined, stem/cup orientation to position both components in a way that the normal range-of-motion (ROM) is contained within an impingement-free prosthetic ROM, aiming for at least 130° flexion, 40° extension, 50° abduction, 50° adduction, 40° external, and 80° internal prosthetic rotation.
3. Re-calculate the zones of impingement-free compliant stem/cup orientation with and without the effect of FT. For studying the incidence of FT after cementless THA, 40 postoperative computed tomography (CT) scans were analyzed by a single investigator (LP).
