The influence of silver nanoparticle morphology on their dissolution kinetics in ultrapure water as well biological effect eukaryotic and prokaryotic cells was examined.
Purpose To report results of sacral decompression and lumbopelvic fixation in neurologically impaired patients with highly displaced, comminuted fracture-dislocations resulting spino-pelvic dissociation. Design Retrospective clinical study. Setting Regional level one trauma center. Patients Nineteen comminuted, irreducible Roy-Camille type 2-4 fractures instability patterns cauda equina deficits were identified over a 6-year period, 18 which met the 12-month minimum follow-up criterion....
Objective To conduct a biomechanical comparison of new triangular osteosynthesis and the standard iliosacral screw for unstable transforaminal sacral fractures in immediate postoperative situation as well early weight-bearing period. Design Twelve preserved human cadaveric lumbopelvic specimens were cyclicly tested single-limb-stance model. A fracture combined with ipsilateral superior inferior pubic rami created stabilized. Loads simulating muscle forces body weight applied. Fracture site...
Presentation of a new triangular osteosynthesis technique that permits early weight-bearing in vertically unstable sacral fractures.Retrospective evaluation consecutive series.Level I trauma center.Thirty-four patients, twenty-eight whom were polytraumatized, all with fractures. This group included eight women and twenty-six men, mean age thirty-five years. Average time between definite operation was thirteen days (range 0 to 28 days).All patients underwent using combination vertical...
Retrospective evaluation of 19 consecutive patients with sacral fracture dislocations and cauda equina syndrome.To review the safety patient impact early surgical decompression, rigid segmental stabilization in high-grade dislocations.The ideal treatment for presenting sacrum resulting from high-energy mechanisms remains unknown. Previous studies consisted multicenter case reviews that showed satisfactory outcomes either nonoperative or a variety methods. However, over last 20 years, no...
The ability of the osteoinductive protein and recombinant human bone morphogenetic protein-2, combined with polylactic glycolic acid porous microspheres autologous blood clot to heal a large segmental defect was tested in rabbit diaphyseal model. Two centimeter nonuniting defects were surgically created bilateral ulnae 50 male New Zealand white rabbits. Each then implanted pastelike acid/blood combination that mixed 5 different concentrations protein-2. forearms radiographically assessed on...
To report the results of intramedullary nailing proximal quarter tibial fractures with special emphasis on techniques reduction.Retrospective clinical study.Level 1 trauma center.During a 36-month period, 456 patients shaft (OTA type 42) or metaphysis 41A2, 41A3, and 41C2) were treated operatively at level center. Thirty-five 37 primarily their formed study group. Thirteen (35.1%) open 22 (59.5%) had segmental comminution. Three intraarticular extensions.Alignment reduction postoperatively...
Video is an essential component of most Massive Open Online Courses (MOOCs) and other forms online learning. This exploratory study examines video as instructional medium investigates the following research questions: • How designed, produced, used in learning contexts, specifically with regard to pedagogy cost? What are benefits limitations standardizing production process?
The shift towards open innovation has substantially changed the academic and practical understanding of corporate innovation. While studies on are burgeoning, most research topic focuses later phases process. So far, impact implications general tendency more openness in industrial science at very front-end process have been mostly neglected. Our paper presents a conceptualization this as new paradigm. Based empirical data current literature, we analyze phenomenon propose four perspectives...
The aim of this study was to reproduce the physico-mechanical antibacterial effect nanocolumnar cicada wing surface for metallic biomaterials by fabrication titanium (Ti) surfaces using glancing angle sputter deposition (GLAD). Nanocolumnar Ti thin films were fabricated GLAD on silicon substrates. S. aureus as well E. coli incubated with nanostructured or reference dense film test samples one three hours at 37 °C. Bacterial adherence, morphology, and viability analyzed fluorescence staining...
Reorganization in the sensorimotor cortex accompanied by increased excitability and enlarged body representations is a consequence of spinal cord injury (SCI). Robotic-assisted bodyweight supported treadmill training (BWSTT) was hypothesized to induce reorganization improve walking function.
Periprosthetic joint infection (PJI) is a devastating complication that leads to enormous economic and health care complaints from affected patients. The aim of this study identify the causative pathogens responsible for PJI, evaluate temporal trends concerning pathogen pattern potential risk factors PJI.This was retrospective analysing total 937 patients suffering PJI hip or knee between 2003 2011.In total, 394 (42.0 %) with arthroplasty (TKA), 477 (50.9 (THA) 64 (6.8 receiving dual-head...
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, to illustrate clinical efficacy this with special reference early postoperative full weight bearing. Design: Prospective cohort study. Setting: Level I trauma centers Bochum Leipzig, Germany. Intervention: Thirty-six depression type thirty-two patients were augmented after...
Acute traumatic pelvic ring instability causes severe pain and associated hemorrhage. Circumferential sheeting provides patient comfort noninvasive, rapid, temporary stability. A bed sheet is readily available, inexpensive, easily applied around the pelvis, disposable.
Lumbopelvic fixation in spinal and pelvic surgery relies on rods or screws as an iliac anchor. Secure placement of with maximum diameter length for the greatest pullout strength requires knowledge structure intraoperative fluoroscopic landmarks secure placement. Therefore, authors evaluated intrailiac length, inner width, cortical thickness three different transiliac screw anchor paths aimed toward anterior inferior spine initiated at tubercle, posterior superior spine, spine. Measurements...
Objectives Evaluation of bacterial adhesion to pure tantalum and tantalum-coated stainless steel versus commercially titanium, titanium alloy (Ti-6Al-4V), grit-blasted polished steel. Design Experimental in vitro cell culture study using Staphylococcus aureus epidermidis evaluate qualitatively quantitatively adherence metallic implants. Methods A assay was performed by culturing S. (ATCC 6538) (clinical isolate) for one hour with tantalum, steel, alloy, implant discs. Adhered living dead...

Adequate exposure of the articular surface distal humerus and elbow joint is required for operative stabilization bicolumnar fractures. The transolecranon approach, which provides complete posterior visualization access to humerus, commonly used. Nevertheless, an olecranon osteotomy other extensor mechanism-disrupting approaches have risks possible complications. Alternative exposures been described primarily total arthroplasty, but these involve extensive potentially devascularizing...
Background: Silver nanoparticles (Ag-NP) are one of the fastest growing products in nano-medicine due to their enhanced antibacterial activity at nanoscale level. In biomedicine, hundreds have been coated with Ag-NP. For example, various medical devices include silver, such as surgical instruments, bone implants and wound dressings. After degradation these materials, or depending on coating technique, silver nanoparticle ion form can be released may come into close contact tissues cells....
