RESUMO
STUDY DESIGN: Descriptive cross-sectional study. OBJECTIVES: To investigate the relationship between perceived social support and depression and to evaluate the role of family, friends and other caregivers in the perception of social support in Iranian individuals with spinal cord injury (SCI). SETTING: Brain and Spinal Cord Injury Research Center, Tehran University of Medical Sciences, Tehran, Iran. METHODS: Social support was evaluated using the Multidimensional Scale of Perceived Social Support questionnaire, which gauges perceptions of support from family, friends and 'important persons'. The presence and severity of depression were assessed with the Beck Depression Inventory (BDI-II-PERSIAN)-a 21-item multiple-choice questionnaire. RESULTS: A total of 140 individuals with SCI were enrolled in the study. The average age of the participants was 29.4±7.9 years; the mean duration of injury was 46.3±46.5 months and most patients were male (72%). Social support and all subscales of social support were numerically greater in males; however, this difference was not statistically significant. The subcategory of friends' support in men was 17.9±7.9 compared to 14.6±8.0 in women (P=0.04). The self-reported social support score (r=-0.387, P<0.001) and subscales of social support, including family (r=-0.174, P=0.045), friends (r=-0.356, P<0.001) and important persons (r=-0.373, P<0.001), were all negatively correlated with depression. CONCLUSION: Higher self-reported perception of social support appears to be associated with lower levels of depression in individuals with SCI. SCI care providers should consider the relationship between social support and depression in their continuing care.

STUDY DESIGN: Descriptive cross-sectional study. OBJECTIVES: Pain is a prevalent complication of individuals with spinal cord injury (SCI). Our objective was to examine the association between social support, socioeconomic factors and psychosocial factors and pain to develop more effective management strategies. SETTING: Brain and Spinal Cord Injury Research (BASIR) Center, Tehran University of Medical Sciences, Tehran, Iran. METHODS: The Persian version of the Brief Pain Inventory was used to measure the pain, and the Multidimensional Scale of Perceived Social Support was used to measure social support through structured face-to-face interviews in SCI individuals. RESULTS: The overall prevalence of pain was 50.7%; 79.3% of individuals had bilateral pain, with lower limbs and back being the most common location. The quality of pain was described as aching (41.4%), tingling (32.9%), pressure (15.7%), coldness (5.7%) and feeling electric shock sensations (4.3%). The frequency of pain in individuals with paraplegia (60.9% vs 45.7%) and incomplete (53.5% vs 52.5%) SCI was higher than with other types of neurological injuries. Patients with a medium level of education had the least pain and those with good economic situation reported higher frequency of having pain (P=0.034). There was no significant relationship between pain and social support. There was a positive correlation between pain and impairment of mood, normal work, relations with other people and lack of sleep (P<0.001). CONCLUSION: These novel findings will inform the development of strategies to manage pain by improving access to health-care facilities and supplies.

Optimal treatment of injuries to the thoracolumbar spine is based on a detailed analysis of instability, as indicated by injury morphology and neurological status, together with significant modifying factors. A classification system helps to structure this analysis and should also provide guidance for treatment. Existing classification systems, such as the Magerl classification, are complex and do not include the neurological status, while the TLICS system has been accused of over-simplifying the influence of fracture morphology and instability. The AOSpine classification group has developed a new classification system, based mainly upon the Magerl and TLICS classifications, and with the aim of overcoming these drawbacks. This differentiates three main types of injury: Type A lesions are compression lesions to the anterior column; Type B lesions are distraction lesions of either the anterior or the posterior column; Type C lesions are translationally unstable lesions. Type A and B lesions are split into subgroups. The neurological damage is graded in 5 steps, ranging from a transient neurological deficit to complete spinal cord injury. Additional modifiers describe disorders which affect treatment strategy, such as osteoporosis or ankylosing diseases. Evaluations of intra- and inter-observer reliability have been very promising and encourage the introduction of this AOSpine classification of thoracolumbar injuries to the German speaking community.

STUDY DESIGN: Retrospective case-control. OBJECTIVES: To characterize changes in American Spinal Injury Association Motor Score (AMS) in patients treated with relative hypertension (HTN) (mean arterial pressure (MAP) > 85 mm Hg for 5 days) with and without preexisting HTN. SETTING: A regional spinal cord injury (SCI) center in Pennsylvania, United States. METHODS: All patients with an acute SCI who were treated with induced HTN (MAP goal above 85) in the intensive care unit (ICU) for at least 5 days were identified. Patients were stratified based on the presence of preexisting HTN, and the change in the AMS between admission and day 5 was determined. Predictors of outcome were identified using correlation analysis and multiple linear regression. RESULTS: Ninety-two patients met inclusion criteria of which 22 had a previous history of HTN. HTN was a predictor of poor early outcome. Patients with HTN had an average decline in their AMS of 7.6, compared with an average decrease of only 0.6 in the AMS of patients without HTN (P=0.04). HTN had no effect (P>0.05) on other in-hospital variables including length of stay, length of stay in the ICU, complications or mortality. Additionally, multiple linear regression analysis demonstrated that diabetes, coronary artery disease and pulmonary disease had no effect on the change in AMS. CONCLUSION: Chronic HTN is an independent risk factor for poor early neurologic recovery in patients treated with relative HTN for an acute SCI. This is independent of age and other comorbidities.

BACKGROUND: In France, attempts to define common ground during spine surgery meetings have revealed significant variability in clinical practices across different schools of surgery and the two specialities involved in spine surgery, namely, neurosurgery and orthopaedic surgery. OBJECTIVES: To objectively characterise this variability by performing a survey based on a fictitious spine trauma case. Our working hypothesis was that significant variability existed in trauma practices and that this variability was related to a lack of strong scientific evidence in spine trauma care. METHODS: We performed a cross-sectional survey based on a clinical vignette describing a 31-year-old male with an L1 burst fracture and neurologic symptoms (numbness). Surgeons received the vignette and a 14-item questionnaire on the management of this patient. For each question, surgeons had to choose among five possible answers. Differences in answers across surgeons were assessed using the Index of Qualitative Variability (IQV), in which 0 indicates no variability and 1 maximal variability. Surgeons also received a questionnaire about their demographics and surgical experience. RESULTS: Of 405 invited spine surgeons, 200 responded to the survey. Five questions had an IQV greater than 0.9, seven an IQV between 0.5 and 0.9, and two an IQV lower than 0.5. Variability was greatest about the need for MRI (IQV=0.93), degree of urgency (IQV=0.93), need for fusion (IQV=0.92), need for post-operative bracing (IQV=0.91), and routine removal of instrumentation (IQV=0.94). Variability was lowest for questions about the need for surgery (IQV=0.42) and use of the posterior approach (IQV=0.36). Answers were influenced by surgeon specialty, age, experience level, and type of centre. CONCLUSION: Clinical practice regarding spine trauma varies widely in France. Little published evidence is available on which to base recommendations that would diminish this variability.

STUDY DESIGN: Survey of expert opinion, feedback and final consensus. OBJECTIVE: To describe the development and the variables included in the International Spinal Cord Injury (SCI) Spinal Interventions and Surgical Procedures Basic Data set. SETTING: International working group. METHODS: A committee of experts was established to select and define data elements. The data set was then disseminated to the appropriate committees and organizations for comments. All suggested revisions were considered and both the International Spinal Cord Society and the American Spinal Injury Association endorsed the final version. RESULTS: The data set consists of nine variables: (1) Intervention/Procedure Date and start time (2) Non-surgical bed rest and external immobilization, (3) Spinal intervention-closed manipulation and/or reduction of spinal elements, (4) Surgical procedure-approach, (5) Date and time of the completion of the intervention or surgical closure; (6) Surgical procedure-open reduction, (7) Surgical procedure-direct decompression of neural elements, and (8 and 9) Surgical procedure-stabilization and fusion (spinal segment number and level). All variables are coded using numbers or characters. Each spinal intervention and procedure is coded (variables 1 through 7) and the spinal segment level is described (variables 8 and 9). Sample clinical cases were developed to illustrate how to complete it. CONCLUSION: The International SCI Spinal Interventions and Surgical Procedures Basic Data Set was developed to facilitate comparisons of spinal interventions and surgical procedures among studies, centers and countries.

STUDY DESIGN: Cross-sectional observational study. OBJECTIVES: To examine variables associated with the development of pressure ulcers in subjects with spinal cord injury (SCI). SETTING: SCI patients under coverage of the State Welfare Organization of Iran. METHODS: Mobile rehabilitation teams gathered data from 20 of the 30 provinces in Iran. There were 8104 SCI patients registered in the database; 7489 patients were included in the analysis. The prevalence of PU in patients aged <10 years was lower than those aged >10; therefore, we used different logistic models for these groups. Likewise, separate models were created for patients who had experienced SCI during the past year versus patients injured >1 year before the evaluation. RESULTS: PU was present in 34.6% of the patients. The variables associated with PU in patients aged <10 years were female gender and the time passed since SCI. In patients aged >11 years, male gender, the time passed since SCI, lower level of education, lack of an intimate partner, quadriplegia and older age presented a significant association with PU. Patients for whom <1 year has passed since SCI, male gender, quadriplegia and older age were associated with PU. And patients for whom >1 year had passed since SCI, male gender, quadriplegia, older age, lower level of education and lack of an intimate partner were associated with PU. CONCLUSION: SCI patients are a heterogeneous group and the risk factors associated with PU may vary in specific subgroups. Different models are needed to describe PU in SCI patients depending on the patient's age and the time passed since SCI.

STUDY DESIGN: Survey of expert opinion, feedback and final consensus. OBJECTIVES: To describe the development of the International Spinal Cord Injury (SCI) Spinal Column Injury Basic Data Set. SETTING: International working group. METHODS: A committee of experts was established to select and define data elements. The data set was then disseminated to the appropriate committees and organizations for comment. All suggested revisions were considered and the final version was endorsed by both the International Spinal Cord Society (ISCoS) and the American Spinal Injury Association (ASIA). RESULTS: The data set consists of seven variables: (1) penetrating or blunt injury, (2) spinal column injury(ies), (3) single or multiple level spinal column injury(ies), (4) spinal column injury level number, (5) spinal column injury level, (6) disc and/or posterior ligamentous complex injury and (7) traumatic translation. All variables are coded using numbers or characters. For variables 1, 2, 3, 4, 6 and 7, response categories are assigned a numeric point score. Variable 5 assigns both characters and numbers to identify level(s) of spinal injured vertebra(e). When there are several distinct and separate levels of injury, then each one is described using variables 4 through 7. CONCLUSION: The International SCI Spinal Column Injury Basic Data Set was developed to facilitate comparisons of spinal column injury data among studies, centres and countries. This data set is part of the National Institute of Neurological Disorders and Stroke Common Data Element project, and tools are now available to assist investigators in collecting this data in their SCI clinical studies.

Bringing evidence to practice is a key issue in modern medicine. The key barrier to information searching is time. Clinical decision support systems (CDSS) can improve guideline adherence. Mounting evidence exists that mobile CDSS on handheld computers support physicians in delivering appropriate care to their patients. Subaxial cervical spine injuries account for almost half of spine injuries, and a majority of spinal cord injuries. A valid and reliable classification exists, including evidence-based treatment algorithms. A mobile CDSS on this topic was not yet available. We developed and tested an iPhone application based on the Subaxial Injury Classification (SLIC) and 5 evidence-based treatment algorithms for the surgical approach to subaxial cervical spine injuries. The application can be downloaded for free. Users are cordially invited to provide feedback in order to direct further development and evaluation of CDSS for traumatic lesions of the spinal column.
RESUMO
STUDY DESIGN: Investigation of burden of traumatic spinal cord injury (SCI) using disease modeling. OBJECTIVES: The present paper is intended to estimate the SCI burden for the year 2008. SETTING: Tehran, capital of Iran. METHODS: Epidemiological data needed to calculate Disability-Adjusted Life-Years (DALYs) for SCI, was estimated according to prevalence, duration and relative risk of mortality using DISMOD software. For DALY calculation, the years of life lost because of premature mortality (YLL) was added to the number of years lost because of disability (YLD). To calculate DALYs for SCI, first year DALY calculated separately and for the next years, the DALY was assessed for six different clinical presentations of traumatic SCI including quadriplegia, quadriparesis, paraplegia, paraparesis, hemiplegia and hemiparesis. RESULTS: In first year following SCI, the DALY was 3772 years, which has 0.5 DALY per 1000 people and YLL/DALY was 89.3%. Following the first year, the DALY was 435 for quadriplegia, 163 for quadriparesis, 868 for paraplegia, 164 for paraparesis, 26 for hemiplegia and 14 for hemiparesis. The total YLL for traumatic SCI was 4077 years and total YLD was 1364 years (total YLL/DALY was 74.9%) and total DALY was 5441 years, (M/F=2.0), which has 0.7 DALY per 1000 people in Tehran in 2008. CONCLUSIONS: This study showed a high burden for SCI. Identifying the risk factors of SCI, and performing cost-effective preventive interventions for reducing burden of SCI is recommended.

STUDY DESIGN: A systematic review of clinical and preclinical literature. OBJECTIVE: To critically evaluate the evidence supporting a role for vasopressor support in the management of acute spinal cord injury and to provide updated recommendations regarding the appropriate clinical application of this therapeutic modality. BACKGROUND: Only few clinical studies exist examining the role of arterial pressure and vasopressors in the context of spinal cord trauma. METHODS: Medical literature was searched from the earlier available date to July 2009 and 32 articles (animal and human literature) answering the following four questions were studied: what patient groups benefit from vasopressor support, which is the optimal hypertensive drug regimen, which is the optimal duration of the treatment and which is the optimal arterial blood pressure. Outcome measures used were the incidence of patients needing vasopressors, the increase of arterial blood pressure and neurologic improvement. RESULTS: Patients with complete cervical cord injuries required vasopressors more frequently than either incomplete injuries or thoracic/lumbar cord injuries (P<0.001). There was no statistical difference in neurologic improvement between patients on vasopressor support with a mean arterial pressure (MAP) of less than 85 mm Hg and those with MAP less than 90 mm Hg. Duration of treatment is often recommended between 5 and 7 days although this is not supported by high-level evidence and no single vasopressor appeared superior over the variety used in clinical treatment. CONCLUSION: There is currently no gold standard on vasopressor support. Based on non-randomized human studies, complete cervical cord injuries require vasopressors more frequently than other spinal cord injuries.

BACKGROUND: The increased risk for venous thromboembolic events following spinal trauma is well established. The purpose of the present study was to examine the literature in order to determine the optimum thromboprophylaxis regimen for patients with acute spinal injuries with or without spinal cord injury. METHODS: EMBASE, MEDLINE, and Cochrane databases were searched from the earliest available date to April 2008 for clinical trials comparing different methods of thromboprophylaxis in adult patients following acute spinal injuries (with or without spinal cord injury). Outcome measures included the prevalences of deep-vein thrombosis and pulmonary embolism and treatment-related adverse events. RESULTS: The search yielded 489 studies, but only twenty-one of them fulfilled the inclusion criteria. The prevalence of deep-vein thrombosis was significantly lower in patients without spinal cord injury as compared with patients with spinal cord injury (odds ratio = 6.0; 95% confidence interval = 2.9 to 12.7). Patients with an acute spinal cord injury who were receiving oral anticoagulants had significantly fewer episodes of pulmonary embolism (odds ratio = 0.1; 95% confidence interval = 0.01 to 0.63) than those who were not receiving oral anticoagulants (either untreated controls or patients managed with low-molecular-weight heparin). The start of thromboprophylaxis within the first two weeks after the injury resulted in significantly fewer deep-vein-thrombosis events than delayed initiation did (odds ratio = 0.2; 95% confidence interval = 0.1 to 0.4). With regard to heparin-based pharmacoprophylaxis in patients with spinal trauma, low-molecular-weight heparin significantly reduced the rates of deep-vein thrombosis and bleeding episodes in comparison with the findings in patients who received unfractionated heparin, with odds ratios of 2.6 (95% confidence interval = 1.2 to 5.6) and 7.5 (95% confidence interval = 1.0 to 58.4) for deep-vein thrombosis and bleeding, respectively. CONCLUSIONS: The prevalence of deep-vein thrombosis following a spine injury is higher among patients who have a spinal cord injury than among those who do not have a spinal cord injury. Therefore, thromboprophylaxis in these patients should start as early as possible once it is deemed safe in terms of potential bleeding complications. Within this population, low-molecular-weight heparin is more effective for the prevention of deep-vein thrombosis, with fewer bleeding complications, than unfractionated heparin is. The use of vitamin K antagonists appeared to be effective for the prevention of pulmonary embolism.

Intramedullary spinal cord neoplasms are relatively uncommon. The most common intramedullary tumors are astrocytomas and ependymomas. Meningiomas can occur as an intradural tumor; however, they are typically in the extramedullary compartment. A 42-year-old male presented with progressive sensory loss in the upper extremities and lower extremity weakness. Pre-operative imaging suggested an intramedullary cervical lesion. To treat the progressive neurological abnormality, surgical resection was planned. At surgery, it was noted that the tumor originated in the cervical spinal cord and extended into the extramedullary region. Histology confirmed the lesion to be a meningioma. This meningioma variant has not previously been described. Spinal meningiomas may occur in locations other than intradural, extramedullary locations, and should be included in the differential diagnosis of intramedullary lesions. Intramedullary meningiomas can be successfully treated with surgery.

BACKGROUND CONTEXT: Prospective studies have failed to demonstrate the superiority of either operative or nonoperative treatment of thoracolumbar fractures. Similar to other surgical fields, research has been limited by the variability in surgical interventions, difficult recruitment, infrequent pathology, and the urgency of interventions. PURPOSE: To outline factors precluding randomized controlled trials in spinal fractures research, and describe a novel methodology that seeks to improve on the design of observational studies. STUDY DESIGN/SETTING: A preliminary report describing an observational study design with clinical equipoise as an inclusion criterion. The proposed methodology is a cohort study with head-to-head comparison of operative and nonoperative treatment regimens in an expertise-based trial fashion. Patients are selected retrospectively by an expert panel and clinical outcomes are assessed to compare competing treatment regimens. Surgeon equipoise served as an inclusion criterion. PATIENT SAMPLE: Patients with closed or open thoracolumbar spinal fracture with or without neurological impairment, presenting to one of two different trauma centers between 1991 and 2005 (N = 760). OUTCOME MEASURES: Homogeneity of baseline clinical and demographic data and distribution of prognostic risk factors between the operative and the nonoperative cohort. METHODS: Patients treated for spine fractures at two University hospitals practicing opposing methods of fracture intervention were identified by medical diagnosis code searches (n = 760). A panel of spine treatment experts, blinded to the treatment received clinically has assessed each case retrospectively. Patients were included in the study when there was disagreement on the preferred treatment, that is, operative or nonoperative treatment of the injury. Baseline and initial data of a study evaluating nonoperative versus operative spinal fracture treatment are presented. RESULTS: One hundred and ninety patients were included in the study accounting for a panel discordance rate of 29%. The distribution of baseline characteristics and demographics of the study populations were equal across the parallel cohorts enrolled in the study, that is, no differences in prognostic factors were observed. CONCLUSIONS: The use of clinical equipoise as an inclusion criterion in comparative studies may be used to avoid selection bias. Using multivariate analysis of retrospectively assembled parallel cohorts, a valid comparison of operative and nonoperative spine fracture treatment strategies and their outcomes is possible.

BACKGROUND CONTEXT: Spinal injuries are common sequelae of falls from hunting tree stands. Significant neurological injury is not uncommon and can result in significant morbidity as well as enormous expenditure of health care dollars. Recent literature on the subject is limited. PURPOSE: The purpose of this study was to identify precipitating causes, characterize the spectrum of spinal injury, and determine potential interventional safety and prevention recommendations. STUDY DESIGN: A retrospective study. METHODS: Medical record review of 22 patients admitted either directly or via referral to a level I spinal cord injury referral center over a 10-year period (1995-2005) after a fall from a hunting tree stand. RESULTS: All patients were men with a mean age of 46 years (range, 27-80 years). Initial acute care hospitalization averaged 10 days (range, 2-28 days). The average height of fall was 18 feet (range, 10-30 feet). Four of 19 falls (21%) occurred during the morning hours, 2 of 19 falls occurred during the afternoon, and 13 of 19 falls (68%) occurred during the evening hours. Time lapse from injury to presentation to an emergency department ranged from 30 minutes to 14 hours. Alcohol use was a factor in 2 of 20 falls (10%). Hypothermia complicated 3 of 21 cases (14%). Associated injuries were present in 12 of 21 patients (57%) and included fractures to the axial and appendicular skeleton, pneumothoraces, a retroperitoneal bleed, and a brachial plexopathy. Eight of 22 patients (37%) sustained injury to the cervical spine. Five of these 8 patients (63%) had neurological deficits (3 complete and 2 incomplete spinal cord injuries). Thirteen of 22 (59%) patients sustained injury to the thoracic or lumbar spine. Ten of these 13 (77%) had neurologic deficits (3 complete and 7 incomplete). Nine of 22 (41%) patients were treated nonoperatively; the remaining 13 (59%) underwent operative intervention. CONCLUSIONS: Falls from hunting tree stands remain a significant cause of spinal injury and subsequent disability. The best intervention for these injuries is prevention. There is a continued need for hunter safety education to reduce the incidence of these injuries with emphasis on safety harness usage, proper installation and annual inspection of tree stands, hunting in groups with periodic contact, the use of communication devices, and abstinence from alcohol consumption while hunting.

So far, there is no widely accepted classification system based on objective findings that can serve as a guide in selecting the treatment method for spinal tuberculosis. This retrospective study evaluates patients with spinal tuberculosis (Pott's disease) treated with different surgical procedures. Our aim was to outline a new classification of spinal tuberculosis. A retrospective review of 76 cases (55 male and 25 female patients) of spinal tuberculosis was conducted. Five of the patients were treated medically, and the others who were treated surgically were classified into three types (I, II and III) according to the new classification system for spinal tuberculosis. All 76 patients were classifiable by this new system. The most common complication observed was local kyphosis (maximum 8 degrees) in type-II patients, but none of the patients needed correction. No neurological deterioration was observed in any of the cases. This new classification system helps in differentiating the various manifestations of spinal tuberculosis and appears to correlate with the surgical treatment of spinal tuberculosis. We believe that this new classification system can be used as a practical guide in the treatment of Pott's disease.
