Hip prosthesis: biomechanics and design
2022Total hip arthroplasty is currently one of the most successful and frequently performed surgical procedures. The hip replacement operation is required if the joint is affected by severe osteoarthritis, which is known to lead to pain and limitations in the joint functions, especially when the patient is not responding to conservative treatments ...

Wear of the Christiansen hip prosthesis
Acta Orthopaedica Scandinavica, 1986The wear was examined in 39 Christiansen total hip prostheses, which were removed because of mechanical loosening after being used 5 (3-11) years. In the polyacetal acetabular cups, the head had made an eccentric defect, the mean volume of which was 680 (180-3310) mm3. The mean penetration of the head into the wall of the cup was 0.8 (0.1-3.2) mm.

SUBHEPATIC MIGRATION OF A HIP PROSTHESIS
The Journal of Bone and Joint Surgery. British volume, 1996The intrapelvic migration of an acetabular cup is a known complication of hip arthroplasty (Eftekhar and Nercessian 1989) but it is usually associated with pain or visceral complications. We report an exceptional case of migration which was painless and without any such complications. Case report.

Hip Arthroplasty with the Metallic Prosthesis
The Journal of Bone & Joint Surgery, 1962The results of 251 operations done for insertion of an internal hip prosthesis were evaluated by examination of the patient in ninety-one cases and by questionnaire in forty-eight. Of these 139 operations, 112 were considered successful (excellent, good, or satisfactory result) and twenty-two unsuccessful (poor or failure).

Cone prosthesis for the hip joint
Archives of Orthopaedic and Trauma Surgery, 2000The shape of the proximal segment of the femur must be taken into account when implanting femoral endoprostheses, especially those intended for cementless anchorage. Numerous femoral prostheses are available for the proximally broadly extending, "trumpet-shaped" morphology.

Furlong Hydroxyapatite-Coated Hip Prosthesis vs the Charnley Cemented Hip Prosthesis
The Journal of Arthroplasty, 2010We report the results of a prospective trial comparing uncemented Furlong hydroxyapatite-coated total hip arthroplasty and cemented Charnley total hip arthroplasty. One hundred ninety-one patients were allocated into 2 groups depending on their year of birth.

Topological optimization in hip prosthesis design
Biomechanics and Modeling in Mechanobiology, 2009With particular interest on total hip arthroplasty (THA), optimization of orthopedic prostheses is employed in this work to minimize the probability of implant failure or maximize prosthesis reliability. This goal is often identified with the reduction of stress concentrations at the interface between bone and these devices.

Acta chirurgiae orthopaedicae et traumatologiae Cechoslovaca, 2001
50 years ago, prosthetic replacement of the hip joint ushered in a new epoch in orthopaedics. Total hip replacement made it possible to remove a severely diseased, painful hip and restore normal function and a normal quality of life to the afflicted patient.
