Determining mineral content variations in bone using backscattered electron imaging.
The mechanical properties of bones are greatly influenced by the ratio of organic constituents to mineral. Determination of bone mineral content on a macroscopic scale is straightforward, butExpand

Complications with hydroxyapatite particulate separation in total hip arthroplasty.
This study reports on the results of the implant and tissue analysis of clinically retrieved hydroxyapatite (HA)-coated implants. Five of the patients with fixed HA-coated stems had been clinicallyExpand

Comparison of human and canine external femoral morphologies in the context of total hip replacement.
The canine is frequently used as a model for human hip arthroplasty research. In order to better understand the appropriateness of the canine as a model for human total hip replacement studies, theExpand

Osteolysis from a press-fit hydroxyapatite-coated implant. A case study.
The clinical and histological results of hydroxyapatite (HA) coating separation from a press-fit total hip arthroplasty 3.3 years after surgery are documented. Semiquantitative histological analysisExpand

Histologic, biochemical, and ion analysis of tissue and fluids retrieved during total hip arthroplasty.
Large amounts of metal and polyethylene debris and high ion readings are found in capsule and fibrous membranes of both loose titanium and cobalt-chromium stems. Prostaglandin E2, interleukin-1, andExpand

Implications of reference axes used for rotational alignment of the femoral component in primary and revision knee arthroplasty.
A careful review of the literature revealed that no data had been reported on the angular difference or similarity between the posterior condylar axis used by many surgeons for primary total kneeExpand

Progression of human bone ingrowth into porous-coated implants. Rate of bone ingrowth in humans.
We report the measured progression of human cancellous bone ingrowth into load-bearing porous-coated titanium implants over 5 time periods (0, 3, 6, 9, and 12 months). There was a statisticallyExpand
