Wear of a composite ceramic head caused by liner fracture.
Third-generation composite ceramics (eg, Delta; DePuy Orthopaedics, Warsaw, Indiana; Ceramtec, Plochingen, Germany) have greatly improved material characteristics compared with second-generation products. This case report presents a patient after total hip arthroplasty with a fractured ceramic liner and a heavily worn ceramic head (both third-generation ceramics) retrieved 9 months after surger...
متن کاملCatastrophic Failure of the Acetabular Polyethylene Liner in Ceramic-on-Polyethylene Total Hip Arthroplasty
INTRODUCTION Catastrophic polyethylene failure is a rare complication of ceramic-on-polyethylene total hip arthroplasty due to the favorable tribological characteristics of ceramic. Failure of the polyethylene liner can be disastrous, increasing periprosthetic osteolysis, metallosis, and risk of dislocation. Complications associated with ceramic-on-polyethylene articulations have been studied e...
متن کاملExtraction of a well fixed but fractured ceramic acetabular liner
Ceramic fractures have been reported to occur in hip replacements, but the techniques used to extract a well fixed but fractured component are not commonly described. We present a case of ceramic liner fracture and validate a modification of a previously reported extraction technique that allowed us to save the acetabular cup and insert a polyethylene liner. With an increasing trend in ceramic ...
متن کاملDelayed diagnosis of catastrophic ceramic liner failure with resultant pelvic discontinuity and massive metallosis
With newer-generation ceramic components used in total hip arthroplasty, component fracture is a rare complication. However rare, when ceramic component fracture does occur, prompt identification and revision is necessary as delay can lead to dramatic failure with resultant metallosis as the extremely hard ceramic debris abrades remaining components. We present a case of a 70-year-old woman wit...
متن کاملFracture of the alumina-bearing couple delta ceramic liner.
The fracture rate of third-generation ceramic liners is greatly reduced compared with first- and second-generation liners because of improvements in the design and manufacturing process. Fractures of the alumina-bearing couple are rare for the same reason.This article describes a case of a fracture of an alumina-bearing couple delta ceramic liner without trauma history that was treated with cer...
