Early stenotic prosthesis failure after implantation of a stentless porcine aortic valve prosthesis [PDF]

Interactive CardioVascular and Thoracic Surgery, 2011
Stentless biological aortic prostheses are used routinely in aortic valve replacement surgery, offering beneficial hemodynamics compared to stented biological valves of similar size. We report here a rare case of early stenotic prosthesis failure of a RootElan stentless porcine aortic valve prosthesis due to swelling at the bottom of the right coronary

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

, 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 ...

Three-dimension-printed custom-made prosthetic reconstructions: from revision surgery to oncologic reconstructions [PDF]

, 2019
Background The use of custom-made 3D-printed prostheses for reconstruction of severe bone defects in selected cases is increasing. The aims of this study were to evaluate (1) the feasibility of surgical reconstruction with these prostheses in oncologic ...

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

arXiv, 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 ...

Application of biologics for ridge preservation/reconstruction after implant removal

Clinical Advances in Periodontics, Volume 12, Issue 4, Page 270-276, December 2022., 2022
Abstract Background The purpose of this review was aimed at providing the rationale supported with a series of cases to apply biologics to enhance orchestrating the healing process at implant removal sites. Summary Implant removal is commonly applied on a daily basis, in particular, in cases that exhibit esthetic failures linked to inadequate implant ...

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

, 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 ...

Failure analysis of a Ti6Al4V cementless HIP prosthesis

Engineering Failure Analysis, 2007
This work investigates the causes of in vivo fracture of a cementless hip prosthesis model manufactured with Ti6A14V alloy. To this end an assessment of geometric characteristics, a fractographic analysis of the fracture surface, and a microstructural study of the stem material were carried out.

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

, 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.
