Implant Complications and Failures: The Fixed Prosthesis

Dental Update, 2002
The 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, 2007
Mechanical 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, 1991
Abstract 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 Analysis of a Titanium Hip Prosthesis

Journal of Failure Analysis and Prevention, 2020
Total 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 ...

Failure prediction of the total hip prosthesis system

Journal of Biomechanics, 1981
Abstract The mechanical failure of the prosthesis-cement-femur system is analyzed by using a two-dimensional finite element model. The strain energy density (SED) criterion is applied to locate potential failure sites in the PMMA and prosthesis stem for five different prosthesis positions.

Cellular basis for failure of joint prosthesis

Bio-Medical Materials and Engineering, 1996
In recent times, loosening of joint prosthesis resulting in failure, is of grave concern to orthopedicians. It is estimated that 50% of total hip replacements become loose after 15 years, and most of them require either revision surgery or resection orthoplasty.

Failure of an uncemented acetabular prosthesis – a case study

Engineering Failure Analysis, 2006
Severe 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

Mechanical Failure of the Repiphysis Expandable Prosthesis

The Journal of Bone and Joint Surgery-American Volume, 2010
The 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.

Ossiculoplasty Failure with Ceramic Ossicular Replacement Prosthesis

ORL, 2010
The stability of ceramic ossicular replacement prosthesis (CORP) in the middle ear was evaluated in 162 ears that had been followed for more than 18 months. The CORP extruded from 8 ears (4.9%) and was dislocated in 6 ears (3.7%). These failures were considered to be due mainly to postoperative tubal dysfunction and disease recurrence.

The inverse prosthesis as a revision prosthesis in failures of shoulder hemiarthroplasty.

La Chirurgia degli organi di movimento, 2005
The authors describe their series of seven cases of complications and failures of shoulder hemiarthroplasty that were submitted to revision surgery involving an inverse prosthesis. This prosthesis has for some time now been indicated in elderly patients with arthropathy caused by rupture of the cuff.
