Silver nanoparticles (Ag-NP) are increasingly used in biomedical applications because of their remarkable antimicrobial activity. In biomedicine, Ag-NP are coated onto or embedded in wound dressings, surgical instruments and bone substitute biomaterials, such as silver-containing calcium phosphate cements. Free Ag-NP and silver ions are released from these(More)
OBJECTIVE Presentation of a new triangular osteosynthesis technique that permits early weight-bearing in vertically unstable sacral fractures. DESIGN Retrospective evaluation of a consecutive series. SETTING Level I trauma center. PATIENTS Thirty-four patients, twenty-eight of whom were polytraumatized, all with vertically unstable sacral fractures.(More)
OBJECTIVES To describe the surgical handling, potential complications, and remodeling of an injectable, osteoconductive calcium phosphate cement (Norian SRS) for joint depression-type calcaneal fractures in humans, and to illustrate the clinical efficacy of this cement with special reference to early postoperative full weight bearing. DESIGN Prospective(More)
INTRODUCTION Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are common procedures in the increasing older population. According to the AAOS, approximately 19,200 Americans are actually living with ipsilateral prosthetic hip and knee leading to 240 interprosthetic fractures annually. Few reviews and case reports give an idea of the obvious(More)
STUDY DESIGN Retrospective chart review. OBJECTIVES The aim of our study was to evaluate the mortality rate and further specific risk factors for Fournier's gangrene in patients with spinal cord injury (SCI). SETTING Division of Spinal Cord Injury, BG-University Hospital Bergmannsheil Bochum, Ruhr-University Bochum, Germany. METHODS All patients with(More)
STUDY DESIGN Retrospective chart review. OBJECTIVES This study was performed to compare the outcome, especially the mortality rate, in patients with and without spinal cord injury (SCI) and necrotizing fasciitis (NF). SETTING Division of Spinal Cord Injury and Department of Plastic and Hand Surgery, BG-University Hospital Bergmannsheil Bochum,(More)
INTRODUCTION The surgical treatment of displaced proximal humeral fractures (ORIF) is a perpetual challenge to the surgeon. For this reason, the principle of polyaxiality was developed to provide an improved primary stability of the fracture through better anchorage of the screws, especially in osteoporotic bone. The aim of this study was to present(More)
Cylindric titanium rods with different surfaces were axially implanted into the femora of sheep. The three surfaces were grit-blasted titanium, plasma-sprayed titanium and plasma-sprayed hydroxyapatite (HA). After 2 months, a 2-cm segment of the femoral shaft was completely resected to load the implant, and the animals were allowed full weight-bearing for 9(More)
Eight patients with sacrum fractures combined with pelvic ring fractures type C were treated using a triangular osteosynthesis after reduction of the fracture. The additional vertical stabilization between the lumbar spine and the posterior iliac crest caused the stability, which is necessary for immediate mobilization of patients. Perfect reduction,(More)
BACKGROUND Extracorporeal life support (ECLS) devices maintain the circulation and oxygenation of organs during acute right ventricular failure and cardiogenic shock, bypassing the lungs. A pulmonary embolism can cause this life-threatening condition. ECLS is a considerably less invasive treatment than surgical embolectomy. Whether to bridge embolectomy or(More)
