OBJECTIVE: The facial region is a commonly fractured site, but the etiology varies widely by country and geographic region. To date, there are no population-based studies of facial fractures in Taiwan. METHODS: We conducted a retrospective study of patients diagnosed with facial fracture and registered in the National Health Insurance Research Database of Taiwan between 1997 and 2011. The epidemiological characteristics of this cohort were analyzed, including the etiology, fracture site, associated injuries, and sex and age distributions...

Objective.:  Rib fractures are present in more than 150,000 patients admitted to US trauma centers each year. Those who fracture two or more ribs are typically treated with oral analgesic drugs and are discharged with few complications. The cost of this care generally reflects its brevity. When a patient fractures three or more ribs, there is an elevated risk of complication. In response, treatments are often broadened and their durations prolonged; this affects cost. While health, function, and survival have been widely explored, patient billing has not...

Renal osteodystrophy (ROD) is a heterogeneous group of metabolic bone diseases complicating progressive chronic kidney disease (CKD). Bone biomarkers and bone imaging techniques may help to assess bone health and predict fractures in CKD but do have important inherent limitations. By informing on bone turnover and mineralization, a bone biopsy may help to guide prevention and treatment of ROD and its consequences. According to a recent survey conducted among European nephrologists, bone biopsies are performed rather exceptionally, both for clinical and research purposes...

The Mesozoic marked a time of experimentation in the tooth morphology of early mammals. One particular experiment involved the movement of three points, or cusps, on the surface of a molar tooth from a line into a triangle. This transition is exemplified by two extinct insectivorous mammals, Morganucodon (cusps in a line) and Kuehneotherium (cusps in a triangle). Here we test whether this difference in cusp arrangement, alongside cusp heights and angles between cusps, is associated with differences in the ability of the teeth to fracture proxy-insect prey...

Deformation twinning rarely occurs in mineral materials which typically show brittle fracture. Surprisingly, it has recently been observed in the biomineral aragonite phase in nacre under high rate impact loading. In this Letter, the twinning tendency and the competition between fracture and deformation twinning were revealed by first principles calculations. The ratio of the unstable stacking fault energy and the stacking fault energy in orthorhombic aragonite is hitherto the highest in a broad range of metallic and oxide materials...

Remote ischemic post‑conditioning (RIPC) is an established method to activate the hypoxia‑inducible factor‑1α (HIF‑1α) pathway, which is involved in the impairment of fracture healing. However, the role of RIPC in fracture healing remains to be fully elucidated. In the present study, rats received fractures and were divided into two groups: Control and RIPC, in which hind limb occlusion was performed. Rats were sacrificed at 7, 14, 28 and 42 days subsequent to tibial fracture. Micro‑computed tomography was performed to measure healing of the bone tissue and biomechanical testing was used to test mechanical strength...

Background: fractures occur more commonly in the thoracic than in the lumbar spine. Physical activity complemented with pharmacological interventions has been advocated as a preventive measure for osteoporosis. However, walking has been shown to produce only a small improvement in spinal bone mineral density. The characteristics of vibration transmission during walking at the lumbar and thoracic spines may be different, and this may help explain the relative incidence of fractures in the two spine regions...

Background: factors affecting mortality after hip fracture surgery have been studied extensively. It has been suggested that do-not-resuscitate (DNR) orders are associated with higher mortality in surgical patients due to less aggressive treatment. However, the effect of DNR orders on mortality in hip fracture patients is unknown. The objective of this study was to investigate the effect of DNR orders on early mortality after hip fracture surgery. Methods: all patients undergoing hip fracture surgery between 2004 and 2015 were included in this retrospective study...

BACKGROUND: Early identification of patients with pelvic fractures at risk for severe bleeding requiring intervention is critical. We performed a multi-institutional study to test our hypothesis that pelvic fracture patterns predict the need for a pelvic hemorrhage control intervention. METHODS: This prospective, observational multi-center study enrolled patients with pelvic fracture due to blunt trauma. Inclusion criteria included shock on admission (SBP<90 or HR>120 and base deficit > 5, and the ability to review pelvic imaging...

Early identification of non-accidental trauma (NAT) is a critical component of pediatric trauma care. Literature searches were conducted related to the association of NAT with seven key areas: history, exam findings (burns, oral trauma, bruising) and imaging (fractures, abdominal and brain injuries). When available, odds ratios (OR) with 95% confidence intervals (CI) for associations with NAT are presented. Systematic reviews have been published in six of the seven key areas and are described. The operational definition of NAT was widely variable across studies, prohibiting meta-analysis...

Trauma, immobilization, and subsequent surgery of the hip and lower limb are associated with a high risk of developing venous thromboembolism (VTE). Individuals undergoing hip fracture surgery (HFS) have the highest rates of VTE among orthopedic surgery and trauma patients. The risk of VTE depends on the type and location of the lower limb injury. Current international guidelines recommend routine pharmacological thromboprophylaxis based on treatment with heparins, fondaparinux, dose-adjusted vitamin K antagonists and acetylsalicylic acid for patients undergoing emergency HFS; however, not all guidelines recommend pharmacological prophylaxis for patients with lower limb injuries...

The dreaded fracture of a root canal instrument is in fact a rare adverse event. Most instrument fractures occur in molar teeth with the highest degree of root curvature. Various treatment options (leaving the fractured instrument with or without apicoectomy, bypassing or removing the fragment) and removing techniques (using ultrasonics, hollow tubes or bypassing and removing with debriders) are discussed. The clinical prognosis for teeth with fractured instruments is not necessarily compromised if appropriate further treatment is undertaken...

By virtue of its excellent bioactivity and osteoconductivity, calcium phosphate cement (CPC) has been applied extensively in bone engineering. Doping a trace element into CPC can change physical characteristics and enhance osteogenesis. The trace element lithium has been demonstrated to stimulate the proliferation and differentiation of osteoblasts. We investigated the fracture-healing effect of osteoporotic defects with lithium-doped calcium phosphate cement (Li/CPC) and the underlying mechanism. Li/CPC bodies immersed in simulated body fluid converted gradually to hydroxyapatite...
