BACKGROUND The role of bone morphogenetic proteins (BMPs) in osseous repair has been demonstrated in numerous animal models. Recombinant human osteogenic protein-1 (rhOP-1 or BMP-7) has now been produced and was evaluated in a clinical trial conducted under a Food and Drug Administration approved Investigational Device Exemption to establish both the safety(More)
For the staged management of infected total knee arthroplasty (TKA), antibiotic laden polymethylmethacrylate (PMMA) spacers have been recommended. Antibiotic-impregnated PMMA spacers target drug delivery, achieving high local levels while limiting the potential for host toxicity associated with parenteral antimicrobial therapy. This study examined the(More)
As the number of total joint arthroplasty and internal fixation procedures continues to rise, the threat of infection following surgery has significant clinical implications. These infections may have highly morbid consequences to patients, who often endure additional surgeries and lengthy exposures to systemic antibiotics, neither of which are guaranteed(More)
Mortality from battlefield wounds has historically declined, thanks to better surgical management, faster transport of casualties, and improved antibiotics. Today, one of the major challenges facing U.S. military caregivers is the presence of multidrug-resistant organisms in orthopaedic extremity wounds. The most frequently identified resistant strains of(More)
Failed ankle arthrodesis represents a significant challenge to the orthopaedist today. The complexity of this problem is further increased when associated with additional complications, such as osteomyelitis, leg length discrepancy, or concomitant foot deformity. In many instances, the only viable salvage alternative is amputation. The authors report 21(More)
Long bone osteomyelitis presents a variety of challenges to the physician. The severity of the disease is staged depending upon the infection's particular features, including its etiology, pathogenesis, extent of bone involvement, duration, and host factors particular to the individual patient (infant, child, adult, or immunocompromised). Long bone(More)
BACKGROUND Surgical site infection (SSI) after total joint arthroplasty (TJA) is a major cause of morbidity. Multiple patient comorbidities have been identified as SSI risk factors including obesity, tobacco use, diabetes, immunosuppression, malnutrition, and coagulopathy. However, the independent effect of multiple individual patient factors on risk of(More)
OBJECTIVES Staphylococcus aureus is the most common organism isolated in osteomyelitis. Methicillin-resistant S. aureus (MRSA) infections are particularly difficult to treat. We evaluated the efficacy of tigecycline and vancomycin with and without rifampicin in a rabbit model of MRSA osteomyelitis. METHODS A 28 day antibiotic therapy with a subcutaneous(More)
