Reverse engineering based integrity assessment of a total hip prosthesis

Procedia Structural Integrity, 2018
The structural strength of a total hip prosthesis was investigated based on a 3D scanning procedure of a hip prosthesis and Finite Element Analysis. 3D scanning was performed by the ATOS 3D scanner, and the CAD model was built using Geomagic Design X ...

Finite Element analysis of stress state in the cement of total hip prosthesis with elastomeric stress barrier

Fracture and Structural Integrity, 2021
In the total hip prosthesis, according to different positions of the patient, there are a variety of loads acting on femoral head which generate stress concentration in the cement called polymethylmethacrylat (PMMA) and consequently in interfaces stem ...

Outcomes of total hip arthroplasty with a standard prosthesis for the affected hip in patients with poliomyelitis sequelae: a mid-term retrospective follow-up study

Journal of Orthopaedic Surgery and Research, 2023
Introduction Total hip arthroplasty for poliomyelitis sequelae could be a technical challenge due to the higher risk for prosthetic dislocation and degenerative changes in the affected limbs.

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

Loosened hip joint prosthesis-decision options

Journal of the Bulgarian Orthopaedics and Trauma Association
For the period 2013-2015, 36 patients underwent revision surgery because of secondary developed complications after primary hip joint replacement surgery. 14 of them were male and 23 – female, with average age 73 years.

Prospective five-year subsidence analysis of a cementless fully hydroxyapatite-coated femoral hip arthroplasty component [PDF]

, 2013
Early subsidence >1.5 mm is considered to be a predictive factor for later aseptic loosening of the femoral component following total hip arthroplasty (THA).
