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

Performance of textured dual mobility total hip prosthesis with a concave dimple during Muslim prayer movements [PDF]

Scientific Reports
The single mobility bearing as a previous bearing design of total hip prosthesis has severe mobility constraints that can result in dislocation during Muslim (people who follow the Islam as religion) prayer movements, specifically shalat that requires ...

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 ...

Stereotactic Body Radiation Therapy (SBRT) in prostate cancer in the presence of hip prosthesis – is it a contraindication? A narrative review [PDF]

BMC Urology
Hip replacement is a common orthopedic surgery in the aging population. With the rising incidence of prostate cancer, metallic hip prosthetics can cause considerable beam hardening and streak artifacts, leading to difficulty in identifying the target ...

Fracture simulation for zirconia toughened alumina microstructure [PDF]

Engineering Computations 30, 5 (2013) 648-664, 2013
Purpose - The purpose of this paper is to describe finite element modelling for fracture and fatigue behaviour of zirconia toughened alumina microstructures. Design/methodology/approach - A two-dimensional finite element model is developed with an actual $Al{_2}O{_3}$ - 10 vol% $ZrO{_2}$ microstructure. A bilinear, time-independent cohesive zone law is

An uncommon case of a bladder injury due to hip prosthesis migration: A case report [PDF]

Urology Case Reports
Bladder injuries, although rare, can occur as a complication of hip surgery, particularly when a hip prosthesis migrates into the bladder. We present the case of a 75-year-old woman with a bladder rupture secondary to prosthesis migration requiring ...

Quantitative Effect of Metal Artefact Reduction on CT-based attenuation correction in FDG PET/CT in patients with hip prosthesis [PDF]

EJNMMI Physics, 2021
Background Metal artefact reduction (MAR) techniques still are in limited use in positron emission tomography/computed tomography (PET/CT). This study aimed to investigate the effect of Smart MAR on quantitative PET analysis in the vicinity of hip ...

Performance of the resurfaced hip. Part 1: the influence of the prosthesis size and positioning on the remodelling and fracture of the femoral neck [PDF]

, 2010
Hip resurfacing is an established treatment for osteoarthritis in young active patients. Failure modes include femoral neck fracture and prosthesis loosening, which may be associated with medium-term bone adaptation, including femoral neck narrowing and ...

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 ...
