A novel classification for atypical Hangman fractures and its application: A retrospective observational study.

Atypical Hangman fractures (AHF) were first formally reported and considered to be more often associated with neurologic deficit in 1993. However, there is a paucity of literature focusing on these fractures. The purpose of the retrospective study was to introduce a new classification scheme for AHF and its application.Sixty-two patients with Hangman fractures were identified. There were 46 (74.2%, 46/62) AHF patients, including 29 type I, 9 type II, 5 type IIa, and 3 type III fractures (Levine-Edwards classification). Based on fracture patterns, incidence, and their impact on neurologic status, a primary classification for AHF was devised. The clinical features of AHF were observed, and a new classification was introduced. The appropriate treatment strategy of AHF was discussed.Of 46 AHF patients, 27 underwent surgical treatment (24 with posterior approach with screw-rod fixation and fusion, 1 with anterior approach by C2/3 discectomy and fusion, and 2 with anterior and posterior approach), and the remaining 19 patients underwent nonoperative treatment. No patient complained severe neck pain at final follow-up. Neurologic status improved 1 to 2 grade in 12 cases with neurologic deficit. All patients achieved bony fusion within the follow-up period.AHF should be recognized as a distinct fracture subtype. The new classification for AHF is based on the feature of fracture patterns, injury mechanism, incidence, and their impact on neurologic deficit. And the new classification is complementary to Levine-Edwards.

Association Between Alendronate Use and Hip Fracture Risk in Older Patients Using Oral Prednisolone.

Oral glucocorticoid treatment increases fracture risk, and evidence is lacking regarding the efficacy of alendronate to protect against hip fracture in older patients using glucocorticoids.

Orbital fractures treated in Auckland from 2010-2015: review of patient outcomes.

The purpose of this study was to review patient outcomes from surgical reconstruction of isolated orbital fractures, performed by the Auckland District Health Board (ADHB) Oral and Maxillofacial Surgery service (OMFS), from 2010 to 2015. In particular, we wished to assess titanium as an orbital reconstructive material and compare outcomes with the international literature.

The role of acromioplasty when repairing rotator cuff tears-no difference in pain or functional outcome at 24 months in a cohort of 2,441 patients.

The role of acromioplasty with rotator cuff repair remains unclear. This study aims to test the null hypothesis-that acromioplasty in conjunction with rotator cuff repair has no effect on improvement in pain or shoulder function at two years follow up.

Evaluation of the Components of the North Carolina Syndromic Surveillance System Heat Syndrome Case Definition.

To improve heat-related illness surveillance, we evaluated and refined North Carolina's heat syndrome case definition.

Closed reduction of a traumatic hip dislocation in children: case report.

Traumatic dislocation of the hip in children is a rare disease. It only represents 5% of hip dislocations in all age groups. Before 10 years, the mechanism is often a minimal domestic accident; after 10 years, the dislocation occurs with the waning of an accident of the public highway. It is different from that of the adult by its rarity, its ease of reduction and better prognosis. This is an emergency trauma: risk necrosis of the femoral head (If delayed reduction). We report a rare case of a 3 year old boy, who suffered from bipolar trauma after a fall near his height of his house causing him a detachment of the right humerus and post-traumatic dislocation of the left hip. The diagnosis was clinically confirmed by the results of standard radiographs and CT scans of the pelvis. The consultation period to emergencies was 5 hours after the trauma. We performed an hour after a closed reduction under general anesthesia for hip dislocation with establishment of a splint pelvic-pedal for analgesic keep for three weeks. The radiological outcome was satisfactory. Peeling Salter I humerus was reduced by orthopedic manner and immobilized by thoracoabdominal plaster to keep for a month. The child was discharged the next day. Reviewed in consultation after a month, the clinical examination showed a steady left hip. Traumatic dislocation of the hip in children is a rare diagnosis, the management should as urgent as possible to overcome the different possible subsequent complications dominated by coxa magna.

Percutaneous vertebroplasty in Moroccan patients with vertebral compression fractures.

Incidence of vertebral compression fractures (VCFs) is increasing due to the increase in human life expectancy and prevalence of osteoporosis. Percutaneous vertebroplasty (PVP) has become a widely used alternative treatment for symptomatic VCFs refractory to medical therapy. It is a minimally invasive technique involving injection most frequently of polymethylmethacrylate (PMMA) directly into the vertebral body through the pedicles. Percutaneous vertebroplasty yields good results in terms of early vertebral stabilization and prompt pain relief. This study describes the experience of the Department of Neurosurgery at Ibn Sina University Hospital (Rabat, Morocco) and assesses short and long term clinical and radiological outcomes and complications of vertebroplasty in a retrospective assessment of 36 vertebral compression fractures in 35 patients (16 men and 19 women subjects) who had been treated with vertebroplasty from November 2006 to December 2014.

Maxillofacial fractures in a budding teaching hospital: a study of pattern of presentation and care.

Previous reports indicated that there is geographic and sociodemographic variation in the epidemiology of maxillofacial fractures. Audit of maxillofacial injuries managed at any institution is therefore necessary to understand the trends and proffer strategies for prevention. We therefore embarked on this study to determine the pattern of maxillofacial fractures and concomitant injuries in our institution.

Comparison of intramedullary fixation and arthroplasty for the treatment of intertrochanteric hip fractures in the elderly: A meta-analysis.

More and more studies conduct to compare intramedullary fixation (IMF) with arthroplasty in treating intertrochanteric hip fractures, but it remains controversy. The aim of this meta-analysis was to find out whether IMF or arthroplasty was more appropriate for treating intertrochanteric hip fractures in elderly patients.

One-stage surgical treatment of cervical spine fracture-dislocation in patients with ankylosing spondylitis via the combined anterior-posterior approach.

The aim of the article is to investigate the efficacy and safety of 1-stage surgical therapy via combined anterior-posterior approach on cervical spine fracture in patients with ankylosing spondylitis (AS).We retrospectively analyzed profiles of 12 AS patients with severe fracture-dislocation of cervical spine received 1-stage combined anterior-posterior surgery in our hospital from October, 2013, to October, 2015, including clinical characteristics, follow-up data, and imaging records. We compared the parameters before and after surgery on the basis of neurological function, bone fusion, Cobb angles of operation segment, Barthel index (BI) score, and incidence rate of complications.A total of 12 patients received 1-stage surgery via combined anterior-posterior approach within 3 days after injury. No severe complications and death occurred. All patients received the successfully anatomical reduction of fracture-dislocation, in which 9 achieved function restoration. The latest follow-up showed the neurological function status of patients was improved. The Cobb angles of operation segments were recovered; the rate of bone fusion was 66.7% at 3 months and 100% at 6 months post-operation. The BI score was improved, 4 cases of moderate dependence and 8 of slight dependence at the latest follow-up compared to 10 of severe dependence and 2 of moderate dependence preoperation. In no cases did severe complications from implanted instrumentation occur.It was high efficacy and safety that the surgical therapy was performed on cervical fracture-dislocation in AS patients by the 1-stage combined anterior-posterior approach. The key of the surgery is the robust stabilization and full decompression of fracture spine at early stage. In addition, if spinal anatomical reduction of fracture segments is difficult to be achieved, the functional restoration should be adopted during the surgery.

Incidence of trigger digits following carpal tunnel release: A nationwide, population-based retrospective cohort study.

The onset of trigger digits after carpal tunnel release (CTR) have been reported inconsistently across different studies. The aim of this study is to assess the incidence of trigger digits after CTR using nationwide population cohort data.We conducted a retrospective cohort study using the Longitudinal Health Insurance Database 2000 (LHID2000) from the National Health Insurance Database (NHIRD) in Taiwan. The LHID2000 contained 1 million beneficiaries randomly selected from the year 2000 Registry for Beneficiaries in NHIRD. We identified 2605 carpal tunnel syndrome (CTS) patients received CTR from 2000 to 2010 (CTR cohort, n = 2605). For each CTR patient, 4 CTS patients without CTR were randomly selected in the control cohort from the general population frequency matched by age, sex, and diagnosed year (non-CTR cohort, n = 10,420). Both cohorts were followed up until the end of 2011 to investigate the occurrence of trigger digits. Adjusted hazard ratios (aHRs) with 95% confidence interval (CI) of trigger digits were estimated using the Cox proportional hazards model after controlling for age, sex, and comorbidities.The CTR cohort had a mean follow-up period of 5.58 ± 3.18 years and the non-CTR cohort had a mean follow-up period of 5.90 ± 3.10 years. The overall risk of trigger digits was 3.63-fold greater in the CTR cohort than in the non-CTR cohort (incidence rate: 12.6 vs 3.38/1000 person-years, aHR: 3.63, 95% CI, 2.97-4.44). The incidence of postoperative trigger digits was highest in the 1st 6 months (incidence rate: 27.9/1000 person-years, aHR: 9.65, 95% CI, 5.27-17.7) and then significantly decreased over time.CTR was significantly associated with the subsequent development of trigger digits, especially in the postoperative 6 months.

The use of 3D-printed titanium mesh tray in treating complex comminuted mandibular fractures: A case report.

Precise bony reduction and reconstruction of optimal contour in treating comminuted mandibular fractures is very difficult using traditional techniques and devices. The aim of this report is to introduce our experiences in using virtual surgery and three-dimensional (3D) printing technique in treating this clinical challenge.

Right femoral pathological fracture caused by primary bone epithelioid angiosarcoma: Case report.

Epithelioid angiosarcoma (EAS) is an extremely rare malignant disease, which accounts no more than 1% of all soft tissue sarcomas. In this article, we would report a new case of EAS with multiple bone destruction and right femoral pathological fracture, which was an even rarer manifestation of EAS.

A biomechanical analysis of plate fixation using unicortical and bicortical screws in transverse metacarpal fracture models subjected to 4-point bending and dynamical bending test.

In the published literature there are controversial data to the biomechanical stability of monocortical comparing to the bicortical fixation of metacarpal fractures. The aim of this study was to compare the biomechanical stability of monocortical and bicortical locking osteosynthesis in quasi-static and dynamic 4-point bending tests of composite third metacarpal bone (4th Gen third metacarpal, Sawbones, Malmö, Sweden) fixed with 7-hole locking plate (XXS System, Biotech-Ortho, Wright, Memphis, TN). The tests to determine quasi-static yield and bending strength as well as fatigue strength were conducted in 4 groups of 10 samples after creating standardized mid-shaft transverse osteotomies using a diamont belt grinder (0.3 mm saw blade). The force applied was the dorsal apex loading, similar to the forces applied to metacarpals during normal finger flexion and extension.In the quasi-static testing, no plate breakage was observed in each group. All metacarpals broke at their thinnest part. The average bending strength of the bicortical samples (10.54 ± 0.998 Nm) was significantly higher comparing to the monocortical samples (8.57 ± 0.894 Nm) (P < .001).In the dynamic loading test, all constructs (8 monocortical samples and 7 bicortical) that failed broke at the osteotomy site and the average fatigue strength did not differ in both groups.Consequently, a unicortical plating method may provide adequate strength and stability to metacarpal fractures based on the results of the cyclical loading representative of in vivo loading.

Residential radon and lung cancer: a cohort study in Galicia, Spain.

Case-control studies show an association between residential radon and lung cancer. The aim of this paper is to investigate this association through a cohort study. We designed an ambispective cohort study using the Galician radon map, Spain, with controls drawn from a previous case-control study. Subjects were recruited between 2002 and 2009. The data were cross-checked to ascertain lung cancer incidence and then analysed using a Cox regression model. A total of 2,127 subjects participated; 24 lung cancer cases were identified; 76.6% of subjects were drawn from the radon map. The adjusted hazard ratio was 1.2 (95%CI: 0.5-2.8) for the category of subjects exposed to 50Bq/m3 or more. This risk rose when subjects from the case-control study were analyzed separately. In conclusion, we did not observe any statistically significant association between residential radon exposure and lung cancer; however, it appears that with a sample of greater median age (such as participants from the case-control study), the risk of lung cancer would have been higher.

Long-term health status and trajectories of seriously injured patients: A population-based longitudinal study.

Improved understanding of the quality of survival of patients is crucial in evaluating trauma care, understanding recovery patterns and timeframes, and informing healthcare, social, and disability service provision. We aimed to describe the longer-term health status of seriously injured patients, identify predictors of outcome, and establish recovery trajectories by population characteristics.

Timing of femoral shaft fracture fixation following major trauma: A retrospective cohort study of United States trauma centers.

Femoral shaft fractures are common in major trauma. Early definitive fixation, within 24 hours, is feasible in most patients and is associated with improved outcomes. Nonetheless, variability might exist between trauma centers in timeliness of fixation. Such variability could impact outcomes and would therefore represent a target for quality improvement. We evaluated variability in delayed fixation (≥24 hours) between trauma centers participating in the American College of Surgeons (ACS) Trauma Quality Improvement Program (TQIP) and measured the resultant association with important clinical outcomes at the hospital level.

Risk of hospitalization with neurodegenerative disease after moderate-to-severe traumatic brain injury in the working-age population: A retrospective cohort study using the Finnish national health registries.

Previous epidemiological studies suggest that working-aged persons with a history of moderate-to-severe traumatic brain injury (TBI) may have an increased risk for developing neurodegenerative disease (NDD) while persons with a history of mild TBI do not. In this comprehensive nationwide study in Finland, we assessed the risk of NDD and history of moderate-to-severe TBI in the working-age population.

Major scientific lessons learned in the trauma field over the last two decades.

John B Holcomb summarizes recent conceptual and practical advances in trauma care, in both military and civilian settings, and presents directions for future research.

The botulinum toxin legend of Reinhard Heydrich's death: The end of "Himmler's brain".

The high-ranking German Nazi Reinhard Heydrich (1904-1942) was one of the main organizers of the mass murder of Jews during the Second World War. He died on June 4, 1942, in Prague after having been wounded in Operation Anthropoid planned by the British intelligence services. Since the 1970s and 1980s, Heydrich's death has been frequently presented in British, American, and French literature as the consequence of a bacteriologic attack. Botulinum toxin would have been used in the grenades or ammunition. We discuss the botulinum toxin hypothesis using the now declassified British archives of Operation Anthropoid and of the chemical and bacteriologic warfare centers to assess this hypothesis.

Neuromarkers of Post-Traumatic Stress Disorder (PTSD) in a patient after bilateral hand amputation - ERP case study.

<b>Introduction</b>. There is a lack in the worldwide literature of reports on the Neuromarkers of Post-Traumatic Stress Disorder (PTSD) in patients after bilateral hand amputation The aim of this study was to test a hypothesis regarding developing Post-Traumatic Stress Disorder (PTSD) in a patient after bilateral hand amputation with the use of Event Related Potentials (ERPs). On the basis of previous research, the amplitudes of P3 ERP components elicited in the cued GO/NOGO tasks have been chosen as candidates for neuromarkers of PTSD. <b>Case study</b>. A 24-year-old patient had undergone bilateral hand amputation 12 months previously. The patient was repeatedly operated on (he had undergone successful bilateral hand replantation) and despite the severity of the injuries, he recovered. However, the patient complained of flashbacks, anxiety and sleep difficulties. Specialist tests showed the presence of PTSD. The patient participated in the cued GO/NOGO task (Kropotov, 2009) with recording 19-channel EEG. P3 GO and NOGO waves in this task were found to be significantly smaller, in comparison to a group of healthy control subjects of the same age (N=23) taken from the HBI normative database ( This observed pattern of ERP waves in the patient corresponds to the pattern found in PTSD patients. <b>Conclusions.</b> ERPs in a GO/NOGO task can be used in the assessment of the functional brain changes induced by chronic PTSD.

To compare the socio-demographic characteristics and type of injury sustained, the use of hospital resources and rates of hospitalisation by injury type, and survival following fall injuries to older Aboriginal people and non-Indigenous Australian people hospitalised for fall-related injuries.

Traumatic spinal cord injury: current concepts and treatment update.

Spinal cord injury (SCI) affects 1.3 million North Americans, with more than half occurring after trauma. In Brazil, few studies have evaluated the epidemiology of SCI with an estimated incidence of 16 to 26 per million per year. The final extent of the spinal cord damage results from primary and secondary mechanisms that start at the moment of the injury and go on for days, and even weeks, after the event. There is convincing evidence that hypotension contributes to secondary injury after acute SCI. Surgical decompression aims at relieving mechanical pressure on the microvascular circulation, therefore reducing hypoxia and ischemia. The role of methylprednisolone as a therapeutic option is still a matter of debate, however most guidelines do not recommend its regular use. Neuroprotective therapies aiming to reduce further injury have been studied and many others are underway. Neuroregenerative therapies are being extensively investigated, with cell based therapy being very promising.

Comprehensive geriatric care reduces acute perioperative delirium in elderly patients with hip fractures: A meta-analysis.

The aim of the current meta-analysis was to assess the treatment effect of comprehensive geriatric care in reducing acute perioperative delirium in older patients with hip fractures, compared with the effect of a routine orthopedic treatment protocol.

Comparison of the efficacy and safety of 3 treatments for patients with osteoporotic vertebral compression fractures: A network meta-analysis.

Osteoporotic vertebral compression fractures (OVCFs) constitute an age-related health problem that affects approximately 200 million people worldwide. Currently, various treatments are performed with the goal of reducing pain, stabilizing the vertebrate, and restoring mobility. In this study, we aimed to assess the efficacy and safety of vertebroplasty (VP), kyphoplasty (KP), and conservative treatment (CT) for the treatment of OVCFs.

Effects of atorvastatin on chronic subdural hematoma: A systematic review.

The high recurrent rate of chronic subdural hematoma (CSDH) has consistently confused the neurosurgeons, and the role of atorvastatin in the management of CSDH has remained unclear over past decade, and atorvastatin seems to be a safe and cost-effective treatment to CSDH. Therefore, it is necessary to conduct a systematic review to discuss the effect of atorvastatin in CSDH.

Anterior cervical distraction and screw elevating-pulling reduction for traumatic cervical spine fractures and dislocations: A retrospective analysis of 86 cases.

Treatment of cervical fracture and dislocation by improving the anterior cervical technique.Anterior cervical approach has been extensively used in treating cervical spine fractures and dislocations. However, when this approach is used in the treatment of locked facet joints, an unsatisfactory intraoperative reduction and prying reduction increases the risk of secondary spinal cord injury. Thus, herein, the cervical anterior approach was improved. With distractor and screw elevation therapy during surgery, the restoration rate is increased, and secondary injury to the spinal cord is avoided.To discuss the feasibility of the surgical method of treating traumatic cervical spine fractures and dislocations and the clinical application.This retrospective study included the duration of patients' hospitalization from January 2005 to June 2015. The potential risks of surgery (including death and other surgical complications) were explained clearly, and written consents were obtained from all patients before surgery.The study was conducted on 86 patients (54 males and 32 females, average age of 40.1 ± 5.6 years) with traumatic cervical spine fractures and dislocations, who underwent one-stage anterior approach treatment. The effective methods were evaluated by postoperative follow-up.The healing of the surgical incision was monitored in 86 patients. The follow-up duration was 18 to 36 (average 26.4 ± 7.1) months. The patients achieved bones grafted fusion and restored spine stability in 3 to 9 (average 6) months after the surgery. Statistically, significant improvement was observed by Frankel score, visual analog scale score, Japanese Orthopedic Association score, and correction rate of the cervical spine dislocation pre- and postoperative (P < .01).The modified anterior cervical approach is simple with a low risk but a good effect in reduction. In addition, it can reduce the risk of iatrogenic secondary spinal cord injury and maintain optimal cervical spine stability as observed during follow-ups. Therefore, it is suitable for clinical promotion and application.
