The Investigation Of A 3-D Human Hip Joint Under The Effect Of Concentrated Force By Using Finite Element Method

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2012
In this study, a three dimensionally modeled human hip joint with and without prosthesis was investigated by using finite element method. In scope of the study, 3 different types of cemented prosthesis namely; Charnley, Muller and Hipokrat were used ...

A radiographic study of hip-joint alignment after prosthetic hip arthoplasty. [PDF]

open access: yes, 2002
Postoperative hip alignment was studied on radiographs in cases of total hip arthroplasty (THA) and of Bipolar Head Prosthesis(BHP), both with MX-1. Postoperative anteroposterior-view radiographs of hip joints of patients with a normal hip joint on the ...

Current and future biocompatibility aspects of biomaterials for hip prosthesis

open access: yes, 2015
The field of biomaterials has turn into an electrifying area because these materials improve the quality and longevity of human life. The first and foremost necessity for the selection of the biomaterial is the acceptability by human body.

Toward a Refined PI‐RADS: The Feasibility and Limitations of More Informative Metrics in Reviewing MRI Scans

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT The Prostate Imaging–Reporting and Data System (PI‐RADS) is a widely‐adopted framework for assessing prostate cancer risk using multiparametric MRI. However, as advancements in imaging and data analytics emerge, PI‐RADS faces pressure to integrate novel quantitative techniques, enhanced imaging protocols, and artificial intelligence (AI ...

The influence of push-off timing in a robotic ankle-foot prosthesis on the energetics and mechanics of walking [PDF]

open access: yes, 2015
Background: Robotic ankle-foot prostheses that provide net positive push-off work can reduce the metabolic rate of walking for individuals with amputation, but benefits might be sensitive to push-off timing.

A New Cemented Hip Prosthesis Concept [PDF]

open access: yesJournal of Medical Devices, 2011
The orthopedic market offers more than 200 hundred different femoral stems, some with scientific published results. The influence of stem geometry relatively to stress distribution on the cement mantle has been addressed by some authors. Stem geometry influences the fatigue mechanism process at the stem-cement interface and may cause aseptic loosening.

Comparison of External Rotation Torque of Short External Rotator Muscles in Hip Flexion Position

open access: yesJournal of Orthopaedic Research, EarlyView.
Preserving the short external rotator muscles of the hip helps prevent dislocation after total hip arthroplasty, but it's unclear which muscles are most critical. This study quantified the external rotation torque in cadaveric hips and found that the obturator externus provides the highest torque during deep hip flexion, where dislocations often occur.
