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

Mechanical failure of omniphase penile prosthesis
Urology, 1988We report a case of mechanical failure due to cable breakage in both cylinders of an OmniPhase penile prosthesis. The failure occurred six weeks after implantation and was manifested by inability to activate the device. X-ray films showed cable fracture at the point of insertion into the activator mechanism bilaterally.

Failure Analysis of a Titanium Hip Prosthesis
Journal of Failure Analysis and Prevention, 2020Total hip arthroplasty or total hip replacement (THR) is a surgical procedure for inserting an implant, which aims to restore the functionality of movements lost due to fractures, joint wear, bone loss and other problems. Although the THR procedure is consolidated in medicine, failures in THR implants associated with different problems are frequently ...

Implant Complications and Failures: The Fixed Prosthesis
Dental Update, 2002The implant-retained fixed prosthesis has been advocated as an effective restoration offering significant benefits over conventional prosthetics. The success of treatment depends on careful pre-surgical planning and prosthesis design. This paper outlines some common complications encountered during the planning, fabrication and maintenance of both ...

Mechanical Failure with Malleable Penile Prosthesis
Urology, 2007Mechanical failure with a malleable penile prosthesis is very rare, and no mechanical failure has been reported with the AMS 650 malleable penile prosthesis. A 67-year-old man, using the AMS 650 malleable penile prosthesis without a problem since 1999, presented with right penile deformity and difficulty in sexual intercourse for the preceding 2 months.

Mechanical failure of a St. Jude Medical prosthesis
The American Journal of Cardiology, 1991Abstract The St. Jude Medical (SJM) prosthetic cardiac valve is a low-profile, bileaflet mechanical valve with an excellent record of durability and a low overall complication rate.1–3 Mechanical failure is a rare occurrence with this valve.4 We report a case of mechanical failure of a SJM prosthesis due to leaflet fracture with subsequent ...

Failure of an uncemented acetabular prosthesis – a case study
Engineering Failure Analysis, 2006Severe wear and aseptic loosening in an uncemented acetabular prosthesis have been observed in a revision surgery carried out at King Edwards VII hospital by L. Taylor and P. Heaton-Adegbile, twelve years following the primary total hip replacement operation. The superior-lateral wall of the polyethylene liner and part of the titanium cup were found to

Migration and failure of the Mecron screw-in acetabular prosthesis
The Journal of Arthroplasty, 1998Early results with the Mecron prosthesis have been variable. We report our experience with this prosthesis at medium- to long-term follow-up. At 5 to 9 years after surgery, 43 patients (49 implants) were reviewed. Radiographic measurements of superior migration, alteration in the opening angle, and thread engagement were made. The failure rate was very

The pathology of the joint tissues and its clinical relevance in prosthesis failure.
Clinical Orthopaedics and Related Research, 1976Thirty-four hip and knee total arthroplasty failures due to infection, loosening, intractable pain and dislocation were examined for synovial and capsular tissue debris.
