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)
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)
Bipolar dislocation of the clavicle ("floating clavicle") is extremely rare. It exists no standardised treatment for this trauma and the treatment is often conservative. This is mainly an anterior displacement of the sternoclavicular joint (type III according to Allman) and a posterior dislocation of the acromioclavicular joint (type IV according to(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)
Human leukocytes (peripheral blood mononuclear cells, PBMC) were overlaid on calcium phosphate bone cement (CBC, Norian SRS) and allowed to settle for 1 h under cell culture conditions. Subsequently, the cells were either left unstimulated (i.e. sham stimulation using cell culture medium), or stimulated with toxic shock syndrome toxin-1 (TSST-1, 10 ng/mL),(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)
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)
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)
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)
