We examined the effects of vancomycin on the compressive strength and fatigue life of bone cement and the pharmacokinetics and antimicrobial activity against methicillin-resistant Staphylococcus aureus of vancomycin eluted from bone cement, both alone and in combination with tobramycin. Two cements, Palacos and Simplex, were tested. Three antibiotic(More)
A retrospective review was conducted to determine the intermediate-term results of a noncustomized, oblong, porous-coated, cementless, acetabular component designed to obtain stability on host bone while maintaining an anatomic hip center. The clinical and radiographic results were reviewed in 18 patients (3 primary, 15 revision). All patients had(More)
Lemierre's syndrome, a systemic anaerobic infection caused by Fusobacterium necrophorum, is characterized by an acute oropharyngeal infection, septic thrombophlebitis of the internal jugular vein, sepsis, and multiple metastatic infections. It commonly leads to septic arthritis and occasionally to osteomyelitis. In the preantibiotic era, this infection was(More)
An unresolved issue in total hip arthroplasty is acetabular reconstruction when there is bone loss that results in pelvic discontinuity, that involves radiation-compromised bone stock, or that is significant enough to exceed the limits of jumbo hemispherical cups. Achieving pain relief and initial and long-term implant stability on host bone are the major(More)
A total knee has been designed to mimic less-compliant medial and more-compliant lateral behavior. In vivo testing compared open-kinematic chain behaviors of cadaver knees in their normal state and after implantation of the knee prosthesis. Specimen's limbs were computed tomography scanned, and infrared arrays on tibia and femur were registered to bone(More)
Lipoxin A4 (LXA4) was competitive with [3H]leukotriene D4 (LTD4) for specific binding to cultured rat glomerular mesangial cells. Half-maximal inhibition was obtained with 100 nM LXA4, compared with 10 nM for unlabeled LTD4. At 10 and 50 nM LXA4 induced low, but significant, increases in mesangial-cell inositol trisphosphate generation: 48% and 44%(More)
BACKGROUND Revision of a failed total hip arthroplasty with massive acetabular bone loss and pelvic discontinuity is a reconstructive challenge. This report presents the mid-term to long-term results of revision total hip arthroplasty with a custom-made porous-coated triflange acetabular prosthesis in a consecutive series of patients with pelvic(More)
In view of its role as a pro-inflammatory mediator in glomerular injury, we investigated the renal cortical microcirculatory responses to the intrarenal arterial administration of platelet-activating factor (PAF) in the anesthetized euvolemic Munich-Wistar rat. Close arterial administration of PAF led to dose-dependent reductions in renal plasma flow rate(More)
BACKGROUND A multicenter retrospective study was conducted to determine the clinical and radiographic results of primary total hip arthroplasty with insertion of the S-ROM modular femoral stem without cement in a series of patients who had been followed for four to seven years. Four centers participated in the study, with one contributing surgeon at each(More)
