Failure of a Novel Ceramic-on-Ceramic Hip Resurfacing Prosthesis

The Journal of Arthroplasty, 2015
We report the early failure of five ceramic-on-ceramic hip resurfacings (CoCHRs). The ceramic used for the acetabular liner was a novel ceramic-composite (two thirds polyurethane and one third alumina ceramic). All cases were revised for increasing metal ion levels (blood cobalt 3.93-208.0 μg/l and chromium 1.57-17.5 μg/l) due to ceramic liner fracture

Failures of the RM finger prosthesis joint replacement system

Journal of Hand Surgery (European Volume), 2011
In our unit a high failure rate of the RM finger prosthesis joint replacement system was noted, prompting a review of cases. A series of patients underwent implantation under the care of one surgeon and the results were monitored. Twenty-one devices were implanted of which 16 were inserted for rheumatoid disease.

Failure of the Uncoated Titanium ProxiLock Femoral Hip Prosthesis

Clinical Orthopaedics and Related Research, 2006
New prostheses should be evaluated for stability and clinical performance. In a prospective randomized clinical trial, we implanted 22 titanium (Ti) and 20 hydroxyapatite-coated (HA) ProxiLock femoral hip prostheses during total hip arthroplasty in 42 patients.
