We report the 12 to 74 month results of our mark I saddle prosthesis after its use as a salvage device for gross loss of pelvic bone stock in 76 patients with failed hip arthroplasties. The implant transmits load between iliac bone and bare polish chrome-cobalt. Our clinical and radiological results indicate that a useful and stable articulation can be(More)
A highly sensitive and specific enzymatic assay for the quantitative determination of 2-[N-[(S)-1-ethoxycarbonyl-3-phenylpropyl]-L-alanyl]-(1S,3S, 5S)-2-azabicyclo[3.3.0]octane-3-carboxylic acid (Hoe 498) and its hydrolysis product Hoe 498-diacid in serum and a GLC method for the simultaneous determination of both compounds in urine are described. Both(More)
Total femur replacement may offer a useful solution in cases of severe trauma or neoplasia and in revision arthroplasty after failed total joint replacement when gross losses of bone have resulted in an unloadable femur and all other methods of treatment would fail to provide the patient with a stable leg. Until recently, total femur components were(More)
SHV extended-spectrum beta-lactamases (ESBLs) arise through single amino acid substitutions in the parental enzyme, SHV-1. In order to evaluate the effect of genetic dissimilarities around the structural gene on MICs, we had previously devised an isogenic system of strains. Here, we present an extended version of the system that now allows assessment of all(More)
The St. Georg total knee prosthesis has been modified to incorporate axial rotation of the tibial component. The kinematics approximate more those of the normal knee and the stress imposed at the bone-cement interface are attenuated, thus reducing the risk of mechanical failure. The construction and laboratory testing are described.
Our clinical experience with different constructions of interposition and arthrodesis nails, used in 3 and 12 patients respectively, is presented. It has shown that cemented intramedullary nailing for the stabilization of long bones and the knee joint using an approach from the site of the defect is a useful additional means in reconstructive bone and joint(More)
Clinical and laboratory investigations have resulted in a new design for the shaft prosthesis of the "St. Georg" model total hip prosthesis, the purpose of which was to minmize the risk of biomechanical complications. The original method of attachment and the same material for the limb were retained for our investigations. It was possible to test the(More)
