Clinical exploration of the international society of limb salvage classification of endoprosthetic failure using Henderson in the application of 3D-printed pelvic tumor prostheses

open access: yesFrontiers in Oncology, 2023
BackgroundThe use of 3D-printed pelvic prosthesis for postoperative reconstruction after pelvic tumor resection has become one of the primary reconstruction methods the incidence of complications related to postoperative prosthesis reconstruction is high.

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

open access: yes, 2014
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).

Detachment of the Amplatzer Device after Interventional Closure of a Mitral Prosthesis Paravalvular Leak

open access: yesInternational Journal of Medical Students, 2018
Background: Paraprosthetic leak is a complication of mitral and aortic valve implantation interventions, that can be treated either through a surgical procedure (repair or replacement of the prosthesis) or by means of a less-invasive percutaneous ...

Revision of reversed shoulder arthroplasty : is a reoperation possible? [PDF]

open access: yes, 2017
Introduction. As the number of reversed shoulder arthroplasty (RSA) procedures increases, the revision rate will also increase. In case of severe bone insufficiency, instability or infection of the primary RSA, revision to another RSA is preferable but ...

Design of EMG-driven Musculoskeletal Model for Volitional Control of a Robotic Ankle Prosthesis [PDF]

open access: yesarXiv, 2022
Existing robotic lower-limb prostheses use autonomous control to address cyclic, locomotive tasks, but they are inadequate to operate the prosthesis for daily activities that are non-cyclic and unpredictable. To address this challenge, this study aims to design a novel electromyography (EMG)-driven musculoskeletal model for volitional control of a ...

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

open access: yes, 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 ...

Enterococcal periprosthetic joint infection: clinical and microbiological findings from an 8-year retrospective cohort study [PDF]

open access: yes, 2019
BACKGROUND: Treatment of enterococcal periprosthetic joint infections (PJI) is challenging due to non-standardized management strategies and lack of biofilm-active antibiotics. The optimal surgical and antimicrobial therapy are unknown.
