Prosthesis retention after an infected hip prosthesis: hip fractures versus primary total hip prosthesis, data from 1998 - 2015 [PDF]

Journal of Bone and Joint Infection, 2018
Background: A prosthetic joint infection (PJI) is a serious complication and specifically a burden for patients after hip fracture surgery, as they are mostly frail elderly patients with multiple comorbidities. Since treatment protocols are lacking there

Polycrystalline Diamond as a Potential Material for the Hard-on-Hard Bearing of Total Hip Prosthesis: Von Mises Stress Analysis. [PDF]

Biomedicines, 2023
Due to polymeric wear debris causing osteolysis from polymer, metal ions causing metallosis from metal, and brittle characteristic causing fracture failure from ceramic in the application on bearing of total hip prosthesis requires the availability of ...

Combining iterative metal artifact reduction and virtual monoenergetic images severely reduces hip prosthesis-associated artifacts in photon-counting detector CT. [PDF]

Sci Rep, 2023
Aim of this study was to assess the impact of virtual monoenergetic images (VMI) in combination and comparison with iterative metal artifact reduction (IMAR) on hip prosthesis-associated artifacts in photon-counting detector CT (PCD-CT). Retrospectively,

Analysis of contact pressure in a 3D model of dual-mobility hip joint prosthesis under a gait cycle

Scientific Reports, 2023
Hip joint prostheses are used to replace hip joint function in the human body. The latest dual-mobility hip joint prosthesis has an additional component of an outer liner that acts as a cover for the liner component.

Minimizing Risk of Failure from Ceramic-on-Ceramic Total Hip Prosthesis by Selecting Ceramic Materials Based on Tresca Stress

Sustainability, 2022
The choice of ceramic-on-ceramic coupling in total hip prosthesis has advantages over couplings with other combinations of materials that use polyethylene and metal materials in terms of high hardness, scratch resistance, low wear rate, and increased ...

Trends of mechanical consequences and modeling of a fibrous membrane around femoral hip prostheses [PDF]

, 1990
In the present study, the effects of a fibrous membrane between cement and bone in a femoral total hip replacement were investigated. The study involved the problem of modeling this fibrous membrane in finite-element analyses, and its global consequences

Calculation of wear (f.i. wear modulus) in the plastic cup of a hip joint prosthesis [PDF]

, 1975
The wear equation is applied to the wear process in a hip joint prosthesis and a wear modulus is defined. The sliding distance, wear modulus, wear volume, wear area, contact angle and the maximum normal stress were calculated and the theoretical ...

Patient-individual hip cups: simulation-based design and sheet metal forming manufacturing [PDF]

, 2013
The revision of an hip prosthesis can have different reasons. One frequent cause, especialley after implantation of a conventional cup, is the so called stress-shielding effect which can lead to a migration or loosening.

Complications of Resection Arthroplasty in Two-Stage Revision for the Treatment of Periprosthetic Hip Joint Infection [PDF]

, 2019
Little data is available regarding complications associated with resection arthroplasty in the treatment of hip periprosthetic joint infection (PJI). We assessed complications during and after two-stage revision using resection arthroplasty.
