Abstract:
An intervertebral disc prosthesis for installation in a spinal column between upper and lower vertebral surfaces includes a first intervertebral plate and a second intervertebral plate. The first intervertebral plate engages the upper vertebral surface. The second intervertebral plate engages the tower vertebral surface. A nonelastomeric resilient body is installed between and engages said intervertebral plates. The nonelastomeric resilient body comprises a plurality of deformable plates and permits relative movement between the first intervertebral plate and the second intervertebral plate.
Abstract:
An adaptable spinal facet joint prosthesis, including a pedicle fixation element; a laminar fixation element; d a facet joint bearing surface having a location adaptable with respect at least one of the pedicle fixation element d the laminar fixation element. Also disclosed is a method of implanting an adaptable spinal facet joint asthesis including the steps of determining a desired position for a facet joint bearing surface; and attaching a prosthesis comprising a facet joint bearing surface to a pedicle portion of a vertebra and a lamina portion of a vertebra to place the facet joint bearing surface in the desired position. The invention also provides a facet joint prosthesis implant tool including a tool guide adapted to guide a vertebra cutting tool; and first and second fixation le alignment elements extending from the saw guide. The invention also provides systems for treating spinal pathologies that include intervertebral discs in combination with spinal and facet joint prostheses.

Abstract:
The present invention provides a method for detecting the presence or absence of, or for discriminating between, blood type variants, including RHD*r's, RHD*DIIIa, RHD*DIVa-2, RHCE*cs s and RHCE*ce733G. The method comprises genotyping a sample obtained from a human subject at one or more positions in intron 7 of the RHD gene and/or in intron 7 of the RHCE gene. The invention also provides products, in particular, probes, primers and kits for use in the method of the invention.
