Disassembly and Dislocation of a Bipolar Hip Prosthesis

Journal of the Formosan Medical Association, 2008
Dislocation of a hip prosthesis is a common complication. In usual cases of hip prosthesis dislocation, the prosthetic femoral head comes out from either the natural acetabular cavity in a bipolar hemiarthroplasty or the prosthetic acetabulum in a total ...

Prediction of time to prosthesis implantation as a function of joint anatomy in patients with developmental dysplasia of the hip [PDF]

, 2019
BACKGROUND: Developmental dysplasia of the hip (DDH) can lead to pain and premature secondary osteoarthritis at an early stage. Joint-preserving osteotomy is an established solution to this problem.

Quality of life and health status after Girdlestone resection arthroplasty in patients with an infected total hip prosthesis

Journal of Bone and Joint Infection, 2019
Introduction: The Girdlestone resection arthroplasty (GRA) is a salvage procedure for a recurrent or persistent prosthetic joint infection of the hip. This procedure negatively impacts the functional outcome and presumably also diminishes health status ...

Transient elastohydrodynamic lubrication analysis of a novel metal-on-metal hip prosthesis with a non-spherical femoral bearing surface

, 2011
Effective lubrication performance of metal-on-metal hip implants only requires optimum conformity within the main loaded area, while it is advantageous to increase the clearance in the equatorial region.
