The aim of this retrospective study was to investigate the clinical outcome of Dalbo®-Rotex® retention elements in a private practice. The majority of the retention elements was fixed with self-adhesive composite cement, and in almost 40% the exposed root surface was additionally covered with composite. The success rate of 96.3% after 24 months in a total of 50 included patients (response rate 48.5%) demonstrated that a simple and cost-effective fixation of removable dentures using prefabricated, chair-side inserted retention elements is feasible...

We report our surgical method used to treat type C distal femur fractures accompanied by patella fractures whereby we approach the articular surface of the femur through the already-fractured patella. We treated 10 patients with type C3 distal femur and patella fractures between May 2013 and April 2015. Because the patella was fractured in all cases, we could approach the articular surface of the distal femur through the transverse gap between the retracted patellar fracture fragments, "transpatellar approach...

Around one third of humeral fractures and 2-6% of all fractures occur to the distal part of the humerus. There is a bimodal distribution differentiating between young male patients with high-energy and elderly female patients with low-energy trauma related to osteoporosis. The AO classification and Dubberley subclassification are used in daily routine. Most fractures are diagnosed on radiographs. For further evaluation, three-dimensional computed tomography is recommended, especially for comminuted or complex fractures...

BACKGROUND: Paradoxically, elderly persons with type 2 diabetes mellitus (T2DM) fracture despite having higher bone density than nondiabetics. Systemic factors associated with aging and T2DM may have detrimental, local effects on the skeleton. One such factor could be by altering the microenvironment of the mesenchymal stem cells (MSCs), multipotent progenitors capable of differentiating into adipocytes or osteoblasts. METHODS: Sera were obtained from four participant groups (n = 40 total, 10 per group): (1) young women with normal glucose tolerance (NGTY), (2) postmenopausal women with NGT), (3) postmenopausal women with impaired glucose tolerance (IGT), and (4) postmenopausal women with T2DM...

Pins exposed out of the skin after surgery for mallet fractures keep patients from washing their hands. The authors buried the tips of all pins under the skin while performing extension block pinning for 14 patients with mallet fractures. The patients were allowed to wash their hands 4 to 5 days postoperatively, without any dressing or splinting. The pins were removed at a mean of 8 weeks postoperatively. Solid union was achieved in all 14 fractures. No pull-out or subsidence of the pin was observed. No patient developed infection or other pin-related complications...

The authors developed a technique for reducing the fractured segment by introducing an elevator through the accessory maxillary ostium (AMO).Through an upper gingivolabial vestibular incision, the fractured segments were exposed. In cases where no cleft was available for inserting the elevator, the blunt end of a Cottle elevator was inserted into the AMO via a nasal approach. The curved blunt end of a Cottle elevator was inserted into the middle meatus and the AMO was felt at the medial wall of the maxillary sinus...

BACKGROUND: Irrigation is one of the key procedures in open fracture management to eliminate pathogens and prevent infection. Metal ion deprivation could inhibit bacterial adhesins and weaken adhesion to the host tissue. EDTA in solution can competitively bind to a metal ion and thus might be able to inhibit bacterial adhesins. QUESTIONS/PURPOSES: (1) Is normal saline-EDTA toxic to fibroblasts and endothelial cells? (2) In a contaminated wound rat model, does irrigation with normal saline-EDTA solution decrease the risk of positive bacterial cultures and infection when compared with normal saline and soap solutions? (3) In an infected wound rat model, are fewer surgical débridements and irrigations with normal saline-EDTA solution required to obtain culture-free wounds when compared with normal saline and soap controls? METHODS: Normal saline-EDTA solution refers to 1 mmol/L EDTA dissolved in normal saline (pH adjusted to 7...

OBJECTIVES: Retrospective evaluation of extended anterior glass-ceramic veneers 7 years after placement in a private practice. MATERIALS AND METHODS: A total of 31 patients (20 females/11 males) underwent restoration with adhesively luted extended veneers that were fabricated using heat-pressed glass-ceramic (Cergo, Dentsply Sirona). A single dentist restored 101 teeth (maxilla, n = 65; mandible, n = 36). Adhesive cementation was performed using an etch-and-rinse adhesive (OptibondFL, Kerr Corporation), and two different dual-curing composite cements (Variolink, Ivoclar Vivadent/Calibra, Dentsply Sirona)...

BACKGROUND: Fifth metatarsal base fractures of the metaphyseal-diaphyseal watershed junction (Jones fracture) are commonly treated with surgical fixation in athletes. Intramedullary screw fixation remains the most utilized construct, although plantar-lateral plating is an alternative. Purpose/Hypothesis: The purpose was to compare the mechanical strength of fracture fixation between an intramedullary screw and plantar-lateral plating. The hypothesis was that plantar-lateral plate fixation would allow for more cycles and higher peak loads before failure, as well as less fracture gapping, than would an intramedullary screw in cadaveric foot specimens with simulated Jones fractures exposed to cantilever bending...

BACKGROUND: Operative management of scapular body fractures, when indicated, typically involves extensive exposure through a posterior approach. We present our experience with a deltoid preserving approach that allows excellent exposure of the fracture lines for reduction and fixation while minimizing muscle detachment and overall tissue trauma. TECHNIQUE: Exposure of the scapula was obtained through a posterior incision. The posterior deltoid was exposed and retracted superiorly while the arm was abducted in accordance with Brodsky et al...

INTRODUCTION: Kirschner wire osteosynthesis is considered to be the standard technique for surgical fixation of displaced supracondylar humeral and distal radial fractures in children. The Kirschner wires can be left exposed or buried under the skin. Advantages of the epicutaneous technique are, e. g. the efficiency (cost, effort) and the possibility for wire removal without the necessity of a second anesthesia. On the other hand, there is a concern about higher infection rates as well as traumatization of the children due to externally visible wires...

BACKGROUND/AIMS: Endothelial-mesenchymal transition (EndMT) has been shown to take part in the generation and progression of diverse diseases, involving a series of changes leading to a loss of their endothelial characteristics and an acquirement of properties typical of mesenchymal cells. Low-intensity pulsed ultrasound (LIPUS) is a new therapeutic option that has been successfully used in fracture healing. However, whether LIPUS can inhibit oxidative stress-induced endothelial cell damages through inhibiting EndMT remained unknown...

BACKGROUND & AIMS: Preterm infants are exposed to a higher risk of developing Metabolic Bone Disease (MBD) with an increased bone fragility, a higher fracture risk and a long-term reduced linear growth and childhood height. Monitoring bone growth has become mandatory in neonatology. Several risk factors have been identified among the population of extremely low birth weight infants, but we still do not know which is the real incidence of MBD since its evaluation is not routinely performed worldwide...

The development of unconventional oil and gas (UOG) resources results in production of large volumes of wastewater containing a complex mixture of hydraulic fracturing chemical additives and components from the formation. Release of these wastewaters into the environment poses potential risks that are poorly understood. Microbial communities in stream sediments form the base of the food chain, and may serve as sentinels for changes in stream health. Iron reducing organisms have been shown to play a role in the biodegradation of a wide range of organic compounds, and to evaluate their response to UOG wastewater, we enriched anaerobic microbial communities from sediments collected upstream (background) and downstream (impacted) of an UOG wastewater injection disposal facility in the presence of hydraulic fracturing fluid (HFF) additives: guar gum, ethylene glycol, and two biocides, DBNPA and Bronopol...

Carbon nanotube (CNT) fibers are promising reinforcements in ceramic matrix composites where the service environments involve extremely high temperatures that are generally beyond 1000 °C. This work focuses on the thermal stability of a direct spun CNT fiber in vacuum and in a wide temperature (25-2000 °C). The microstructure, mechanical and electrical properties of the fibers as a function of the heat-treatment temperature were investigated. The results show that high temperature exposure could increase the defect density and loosen the packing state of the fiber, but enhance the graphitization degree of the CNTs...
