Risk Factors for Prosthesis Failure in Pulmonary Valve Replacement
The Annals of Thoracic Surgery, 2011After initial right ventricular outflow tract reconstruction, replacement of the pulmonary valve (PVR) with a bioprosthetic valve may be performed. Bioprosthetic valves fail (PVF) and require repeat replacement. Identification of risk factors for PVF would be useful for clinicians choosing among various options for the initial PVR.We retrospectively ...

Failure of an uncemented thumb carpometacarpal joint ceramic prosthesis
Journal of Hand Surgery (European Volume), 2017Thumb carpometacarpal joint replacement is associated with high rates of loosening and failure. We present our results for an uncemented ceramic–ceramic total joint prosthesis with a reverse ball-and-socket design and bioactive coating. Between 2008 and 2012, 29 prostheses were inserted into 28 patients (mean age 63 years) with advanced osteoarthritis.

Multidisciplinary approach for in-deep assessment of joint prosthesis failure
2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009In spite of advancement in biomaterials and biomechanics, in development of new osteo-integrative materials and coatings, and in macro- micro- component design, a non negligible fraction of the implanted prosthesis fails before the expected lifetime. A prospective observational clinical study has been conducted to define and apply a set of experimental

Vascular Prostheses Performance Assessment of Vascular Prosthesis Failure
Artificial Organs, 1986Abstract: During 30 years of active participation in clinical vascular surgery and the screening and development of vascular prostheses, >450 different fabrications have been evaluated. Vascular prosthesis retrieval and analysis during this period of time have been systematized, and >40 different causes of failure of vascular prostheses have ...

Mechanical Failure of the Repiphysis Expandable Prosthesis
The Journal of Bone and Joint Surgery-American Volume, 2010The current treatment of osteosarcoma includes neoadjuvant chemotherapy followed by wide resection of the tumor and postoperative chemotherapy. While amputation of the extremity was once the mainstay of treatment, medical and surgical developments over the last several decades have led to the success of limb-salvage surgery1,2.

Symptomatic failure of snap-on bipolar radial head prosthesis
Journal of Shoulder and Elbow Surgery, 2009As the design of prosthetic radial head components improves, and the understanding of the necessity for early restoration of elbow and forearm stability in complex elbow trauma increases, prosthetic radial head replacement is becoming more common. In fact, open reduction and internal fixation of complex radial head fractures has been shown to have ...

Failure of the Jonas Prosthesis
Journal of Urology, 1986A total of 27 patients received the standard Jonas silicone-silver penile prosthesis. The procedure was done at 3 separate hospitals by 2 surgical teams. Four patients who were reported on previously presented consecutively to our clinic with failed penile rigidity and complete multiple wire fractures were found at reoperation. Therefore, the remaining
