Anterior Column Reconstruction of Destructive Vertebral Osteomyelitis at the Thoracolumbar Spine with an Expandable Vertebral Body Replacement Implant: A Retrospective, Monocentric Radiological Cohort Analysis of 24 Cases. J Clin Med 2024; 13:296. [PMID: 38202303 PMCID: PMC10780050 DOI: 10.3390/jcm13010296] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 12/21/2023] [Accepted: 12/28/2023] [Indexed: 01/12/2024] Open
Abstract
BACKGROUND Vertebral osteomyelitis (VO) often necessitates surgical intervention due to bone loss-induced spinal instability. Anterior column reconstruction, utilizing expandable vertebral body replacement (VBR) implants, is a recognized approach to restore stability and prevent neurological compromise. Despite various techniques, clinical evidence regarding the safety and efficacy of these implants in VO remains limited. METHODS A retrospective cohort analysis, spanning 2000 to 2020, was conducted on 24 destructive VO cases at a Level 1 orthopedic trauma center. Diagnosis relied on clinical, radiological, and microbiological criteria. Patient demographics, clinical presentation, surgical interventions, and radiological outcomes were assessed. RESULTS The study included 24 patients (62.5% male; mean age 65.6 ± 35.0 years), with 58% having healthcare-associated infections (HAVO). The mean radiological follow-up was 137.2 ± 161.7 weeks. Surgical intervention significantly improved the bi-segmental kyphotic endplate angle (BKA) postoperatively (mean -1.4° ± 13.6°). However, a noticeable loss of correction was observed over time. The study reported a mortality rate of 1/24. CONCLUSIONS Anterior column reconstruction using expandable VBR effectively improved local spinal alignment in destructive VO. However, the study underscores the necessity for prolonged follow-up and continuous research to refine surgical techniques and postoperative care. Addressing long-term complications and refining surgical approaches will be pivotal as the field progresses.

Hoffmann MF, Kuhlmann K, Schildhauer TA, Wenning KE. Improvement of vertebral body fracture reduction utilizing a posterior reduction tool: a single-center experience. J Orthop Surg Res 2023; 18:321. [PMID: 37098619 PMCID: PMC10131469 DOI: 10.1186/s13018-023-03793-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Accepted: 04/11/2023] [Indexed: 04/27/2023] Open
Abstract
BACKGROUND Extensive research regarding instabilities and prevention of kyphotic malalignment in the thoracolumbar spine exists. Keystones of this treatment are posterior instrumentation and anterior vertebral height restoration. Anterior column reduction via a single-stage procedure seems to be advantageous regarding complication, blood loss, and OR-time. Mechanical elevation of the anterior cortex of the vertebra may prevent the necessity of additional anterior stabilization or vertebral body replacement. The purpose of this study was to examine (1) if increased bony reduction in the anterior vertebral cortex could be achieved by utilization of an additional reduction tool, (2) if postoperative loss of vertebral height could be reduced, and (3) if anterior column reduction is related to clinical outcome. METHODS From one level I trauma center, 173 patients underwent posterior stabilization for fractures of the thoracolumbar region between 2015 and 2020. Reduction in the vertebral body was performed via intraoperative lordotic positioning or by utilization of an additional reduction tool (Nforce, Medtronic). The reduction tool was mounted onto the pedicle screws and removed after tightening of the locking screws. To assess bony reduction, the sagittal index (SI) and vertebral kyphosis angle (VKA) were measured on X-rays and CT images at different time points ((1) preoperative, (2) postoperative, (3) ≥ 3 months postoperative). Clinical outcome was assessed utilizing the Ostwestry Disability Index (ODI). RESULTS Bisegmental stabilization of AO/OTA type A3/A4 vertebral fractures was performed in 77 patients. Thereof, reduction was performed in 44 patients (females 34%) via intraoperative positioning alone (control group), whereas 33 patients (females 33%) underwent additional reduction utilizing a mechanical reduction tool (instrumentation group). Mean age was 41 ± 13 years in the instrumentation group (IG) and 52 ± 12 years in the control group (CG) (p < 0.001). No differences in terms of gender and comorbidities were found between the two groups. Preoperatively, the sagittal index (SI) was 0.69 in IG compared to 0.74 in CG (p = 0.039), resulting in a vertebral kyphosis angle (VKA) of 15.0° vs. 11.7° (p = 0.004). Intraoperatively, a significantly greater correction of the kyphotic deformity was achieved in the IG (p < 0.001), resulting in a compensation of the initially more severe kyphotic malalignment. The SI was corrected by 0.20-0.88 postoperatively, resulting in an improvement of the VKA by 8.7°-6.3°. In the CG, the SI could be corrected by 0.12-0.86 and the VKA by 5.1°-6.6°. The amount of correction was influenced by the initial deformity (p < 0.001). Postoperatively, both groups showed a loss of correction, resulting in a gain of 0.08 for the SI and 4.1° in IG and 0.03 and 2.0°, respectively. The best results were observed in younger patients with initially severe kyphotic deformity. Considering various influencing factors, clinical outcome determined by the ODI showed no significant differences between both groups. CONCLUSION Utilization of the investigated reduction tool during posterior stabilization of vertebral body fractures in a suitable collective of young patients with good bone quality and severe fracture deformity may lead to better reduction in the ventral column of the fractured vertebral body and angle correction. Therefore, additional anterior stabilization or vertebral body replacement may be prevented.

Abstract
Background For the treatment of unstable thoracolumbar fractures, this study compared the results of short-segment fixation with fracture level inclusion (SSFIFL) with long-segment pedicle fixation (LSPF). Methodology In this prospective case series study conducted from January 2015 to January 2019, 80 patients with partial spinal cord lesions were investigated. For the comparison, two groups of 40 patients each were chosen and treated with SSFIFL and LSPF. The outcomes were measured using pre and postoperative radiological parameters and clinical parameters. The radiographic variables included the kyphotic angle with loss of correction, kyphotic deformation, and the Beck index. Mean blood loss, operative time, and cost-effectiveness were also examined for clinical indicators such as the American Spinal Injury Association Impairment Scale, Visual Analog Scale (VAS), and Oswestry Disability Index (ODI). Results There were no substantial variations between the groups regarding age or gender, trauma etiology, fracture level, or fracture pattern. Between the two categories, there appeared to be no notable change in radiological indicators such as kyphotic angle, kyphotic deformation, and Beck index at the end of follow-up (p = 0.120, 0.360, and 0.776, respectively). Both groups had similar neurological outcomes (p = 0.781). In terms of ODI and VAS, statistically, there was no discernible difference (p = 0.567 and 0.161, respectively). In this study, however, there was less surgical time, blood loss, and implant cost (p = 0.05). Conclusions When fracture level is included in a short-segment fixation, the radiological and clinical results are comparable to long-segment posterior fixation. Ultimately, this treatment has proven to be not only a motion segment-saving procedure but also cost-effective.

Abstract
OBJECTIVE To see if, in elderly patients with traumatic thoracolumbar fracture, standing X-rays with orthoses 24-48h after admission can predict vertebral collapse after consolidation. MATERIAL AND METHODS Prospective cohort study endorsed by the Clinical Research Ethics Committee. INCLUSION CRITERIA age >65 years, acute thoracolumbar junction fracture due to fall, hospital admission, treatment with orthesis. EXCLUSION CRITERIA various levels, suspected malignancy, non-immediate fracture or atraumatic. VARIABLES Farcy index (F), regional kyphosis (C: Cobb from cranial to caudal to broken vertebra) - both measured at admission (F0 and C0), at 24-48h in standing position with orthesis (F1 and C1) and 3 months, without brace (F2 and C2), collapse (increase from F0 to F1 -F0F1- and from F1 to F2 -F1F2-; as well as from C0 to C1 -C0C1- and from C1 to C2 -C1C2-), age and gender. STATISTICAL ANALYSIS R package. RESULTS Series of 40 patients, with a mean age of 75 years (66-87). Nine men and 31 women. Neither gender nor age were correlated with any variable. Six required surgery at follow-up. There were no differences in F1, C1, F0F1 or C0C1 between the six patients who required surgery and the other 34. Subsequently, data analysis was performed only for those patients who did not require surgery. The values obtained in the Farcy index were 8°+7° (F0), 12°+7° (F1) and 15°+8° (F2) and in kyphosis (three vertebrae, Cobb) they were: C0=8°+13°; C1=11.5°+14° and C2=13°+13°. There was a correlation of F2 with F0 and F1 (p<.001), with F0F1 (p=.038) and F1F2 (p=.007). The most powerful was with F1 (Rho Spearman=.889 (95% CI=.776-.947), with a Linear Regression line: F2=2.61288+F1×1.01237 (R2=.79). C2 was correlated with C0 and C1 (p<.001), especially with C1 (Rho Spearman=.952, 95% CI=.899-.977). Linear regression: C2=2.23371+C1×0.93758 (R2=.927). CONCLUSIONS Immediate standing collapse predicts alignment at consolidation (3 months). It is therefore advisable to perform that radiography in the follow-up protocol.

Abstract
Background A thoracolumbar burst fracture (BF) is a severe type of compression fracture, which is the most common type of traumatic spine fractures. Generally, surgery is the preferred treatment, but whether the optimal approach is either an anterior or a posterior approach remains unclear. This study aims to determine whether either method provides an advantage. Methods Following PRISMA guidelines, a systematic review was conducted, identifying studies comparing anterior versus posterior surgical approaches in patients with thoracolumbar BFs. Data were analyzed using Review Manager 5.3. Seven studies were included. Results An operative time of 87.97 min (53.91, 122.03; p<0.0001) and blood loss of 497.04 mL (281.8, 712.28; p<0.0001) were lower in the posterior approach. Length of hospital stay, complications, reintervention rate, neurological outcomes, postoperative kyphotic angle, and costs were similar between both groups. Conclusions Surgical intervention is usually selected to rehabilitate patients with BFs. The data obtained from this study suggest that a posterior approach represents a viable alternative to an anterior approach, with various advantages such as a shorter operative time and decreased bleeding.

Abstract
Background: The purpose of this study was to evaluate the effectiveness of minimally invasive posterior mono-axial pedicle screws fixation in the treatment of thoracolumbar burst fractures. Methods: In the present study, we analyzed 98 patients retrospectively who had thoracolumbar burst fractures without a neurological deficit. Patients were divided into two groups: mono-axial pedicle screw fixation group (n = 52) and poly-axial pedicle screw fixation group (n = 46). We collected clinical data (visual analog scale (VAS) score for back pain) and included radiographic measurements. Results: Sagittal index was significantly improved at postop and last follow-up in the mono group and the poly group. The mono group was better for reducing and maintaining anterior vertebral height. For the mono group, the mean postoperative regional kyphosis correction rate was 62.31%, and correction loss was 14.18% in late follow-up. For the poly group, the mean postoperative regional kyphosis correction rate was 52.17%, and correction loss was 33.42% in late follow-up. The mono-axial pedicle screw group had a good correction rate and reduced the risks of correction loss. The mean VAS scores for back pain improved by 2.4/2.5 and 3.8/4.2 for the mono and poly groups, respectively. There was no significant difference between groups. Conclusions: The mono-axial pedicle screw fixation was better for reducing and maintaining anterior vertebral height and regional kyphosis. Therefore, the mono-axial pedicle screw is a better optional instrumentation to treat thoracolumbar vertebral fractures.

Abstract
BACKGROUND Long-segment posterior fixation has been used as a mainstay treatment of spine fracture-dislocations. Studies using short-segment posterior fixation in cases of thoracolumbar fracture-dislocation are limited. We describe our experience of 26 patients with thoracolumbar fracture-dislocation treated by short-segment or long-segment posterior spinal fixation and fusion. METHODS This is a single-center retrospective study of 26 patients with thoracolumbar fracture-dislocation treated by long-segment (group 1, n = 12) and short-segment posterior instrumentation (group 2, n = 14). Clinical (visual analog scale [VAS], Oswestry Disability Index [ODI]), neurological (American Spinal Injury Association [ASIA] scale), radiological (kyphotic angle, translational percentage, and displacement angle), and surgical (blood loss, operative time) outcomes and complications were recorded with each method. The mean follow-up period was 8.64 months (6-20 months). RESULTS The mean duration of surgery was 3.92 ± 0.67 hours in group 1 and 3.21 ± 0.54 hours in group 2, and mean blood loss was 583.33 ± 111.5 mL and 478.6 ±112.2 mL in groups 1 and 2, respectively (P < .05). There was no radiologically visible pseudarthrosis, implant failure, or screw breakage in either group at follow up with no statistically significant difference between the 2 groups with regard to the radiological outcome (P > .05). Two patients in group 1 and 6 patients in group 2 improved after surgery at least 1 ASIA grade. VAS and ODI improved in both groups at the final follow up. CONCLUSIONS Short-segment fixation can be used for treating fracture-dislocation patients, as it results in less blood loss, decreased intraoperative time, and saves fusion segments with similar radiological and clinical outcomes as long-segment fixation. LEVEL OF EVIDENCE 3.

Abstract
Management of patients with thoracolumbar burst fractures who do not have a neurologic injury has historically been controversial. Whilst management with an orthosis has gained popularity over surgical management, more recent evidence has suggested that even an orthosis may be unnecessary. A systematic review of the literature comparing orthosis with no orthosis in the management of thoracolumbar burst fractures in patients without neurological deficit was conducted. A risk of bias assessment was performed according to the Cochrane Collaboration Back Review Group. The quality of evidence was assessed according to the GRADE system. Two trials met the eligibility criteria. The functional outcomes, radiologic measures of kyphosis, pain scores, and quality of life scores were equivalent between the orthosis and the no orthosis groups. The level of evidence ranged from very low to moderate for the outcomes evaluated. The rate of complications and the rate of failure of treatment requiring surgery was low. Evidence from two small randomised controlled trials suggests that there are equivalent outcomes between treatment with and without an orthosis. Larger trials are needed to assess the treatment effect with greater confidence.

Abstract
ABSTRACT Objective To compare the Schanz screw insertion angle and the loss of the regional kyphosis correction in thoracolumbar burst fractures following posterior short instrumentation surgery. Methods Patients with a thoracolumbar burst fracture between levels T11-L2 were divided into two groups (parallel and divergent) according to the angle formed between the Schanz screw and the vertebral plateau. Regional kyphosis was evaluated in preoperative, immediate postoperative and last follow-up radiographs. Results Of the 58 patients evaluated, 31 had a parallel assembly and 27 had a divergent assembly. When we analyzed the angle of kyphosis, no statistical difference was observed between the pre- and postoperative radiographs. However, a statistical difference in the last follow-up radiographs and in the final loss of the kyphosis correction was confirmed. Conclusion The insertion of Schanz screws with a divergent assembly presents better radiographic results with less loss of kyphosis correction angle when compared with the parallel assembly technique. Level of Evidence III; Retrospective cohort study.

Abstract
The aim of this systematic review was to evaluate the surgical, radiological, and functional outcomes of posterior-only versus combined anterior-posterior approaches in patients with traumatic thoracolumbar burst fractures. The ideal approach (anterior-only, posterior-only, or combined anterior-posterior) for the surgical management of thoracolumbar burst fracture remains controversial, with each approach having its advantages and disadvantages. A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed (registration no., CRD42018115120). The authors reviewed comparative studies evaluating posterior-only approach compared with combined anterior-posterior approaches with respect to clinical, surgical, radiographic, and functional outcome measures. Five retrospective cohort studies were included. Postoperative neurological deterioration was not reported in either group. Operative time, estimated blood loss, and postoperative length of stay were increased among patients in the combined anterior-posterior group in one study and equivalent between groups in another study. No significant difference was observed between the two approaches with regards to long-term postoperative Cobb angle (mean difference, -0.2; 95% confidence interval, -5.2 to 4.8; p =0.936). Moreover, no significant difference in functional patient outcomes was observed in the 36item Short-Form Health Survey, Visual Analog Scale, and return-to-work rates between the two groups. The available evidence does not indicate improved clinical, radiologic (including kyphotic deformity), and functional outcomes in the combined anterior-posterior and posterior-only approaches in the management of traumatic thoracolumbar burst fractures. Further studies are required to ascertain if a subset of patients will benefit from a combined anterior-posterior approach.

Abstract
STUDY DESIGN This was a meta-analysis study. OBJECTIVE To compare different posterior spine fixation methods for burst fracture fixation. SUMMARY OF BACKGROUND DATA This study was performed to elucidate if the current body of literature supports one posterior spinal fusion fixation method for burst fracture to minimize the rate of implant failure and progression of posttraumatic kyphosis. MATERIALS AND METHODS An extensive electronic search was conducted using PubMed for pertinent articles. The articles were examined against the inclusion and exclusion criteria. Data pertaining to kyphosis angle, Frankel score, vertebral level, blood loss, operation time, hospital stay, postoperative bracing, instrument failure, complications, and follow-up were collected. A random effects model was chosen due to variation among the individual studies' patient populations and surgical methods. RESULTS A total of 23 publications were eventually deemed eligible according to the criteria and included into this study. The group with 2 levels above and 1 below with intermediate screws had the greatest maintenance of spine kyphosis and lowest implant failure at final follow-up (P<0.001). There was no difference between the periods of hospital stay (P=0.788) and blood loss (P=0.154) among different tiers. CONCLUSIONS A fixation method consisting of 2 levels above and 1 below with intermediate screws for the thoracolumbar burst fractures showed the highest correction of kyphosis angle both at immediate and final follow-up and also the lowest implant failure at final follow-up.

Abstract
STUDY DESIGN Case series. OBJECTIVE Thoracolumbar burst fractures (TLBF) are the most frequent type of spinal fractures. Approximately half of the patients are neurologically intact and their treatment is still debatable. Gender could influence outcome after surgical procedures, but this is still unclear in patients sustaining a spinal fracture. The aim of this study was to investigate how gender influences health-related quality of life (HRQOL) and disability in patients operated on for TLBF. METHODS We identified 44 neurologically intact patients from a consecutive series of patients treated surgically for a single-level traumatic burst fracture (AOSpine Subaxial Classification System A3) in the thoracolumbar transition area (Th12-L2). At 1 year after surgery, they were evaluated using the SF-36v2 questionnaire to assess HRQOL and Oswestry Disability Index (ODI) questionnaire to evaluate disability. RESULTS Male patients scored higher in each item of the SF-36v2, with significant differences (P < .05) for Physical Function (PF), Bodily Pain (BP), and Social Function (SF). Male patients also had lower disability scores. Overall ODI score had a strong correlation with Physical Function, Role-Physical, Bodily Pain, Vitality, Mental Health, and overall Physical Component Summary (PCS) of the SF-36 in women, but only with Physical Function, Role-Physical, Role-Emotional, and PCS in men. CONCLUSIONS In this study, male patients reported better outcomes at 1 year after surgery for TLBF than women. Disability strongly correlated with the overall HRQOL, physical and mental health in women, but not in men. We found gender-related differences favoring men after surgical interventions for spinal fractures.

Abstract
This study aims to evaluate the application of multimodal intraoperative monitoring (MIOM) in surgical treatment for spine burst fracture and dislocation (SBFD) patients.Eleven patients who underwent posterior reduction and instrumentation (PRI) for SBFD from June 2014 to July 2016 were included into the study. The function of the spinal cord was monitored by MIOM. The muscle strength of the lower extremities and American Spinal Injury Association (ASIA) scores were, respectively, evaluated (before surgery, and at 1, 3, 6, and 12 months after surgery). Furthermore, the extent of reduction was also assessed.Muscle strength recovery, ASIA score changes, and the extent of reduction were correlated with MIOM results. Among the 11 patients who received surgery under MIOM, 8 patients with negative MIOM results during the operation did not demonstrate neurological deterioration postoperatively and exhibited improvements in ASIA scores during follow-ups. However, among the 3 patients who encountered MIOM events (case 4, 7, and 8), 2 patients avoided nerve lesion and 1 patient suffered from neurologic deterioration postoperatively.The application of MIOM technology during PRI surgery may detect spinal cord impairment at the early stage, and operative schemes can be modified before permanent nerve compromise is triggered by surgical manipulation.

Abstract
STUDY DESIGN Prospective, correlational, exploratory, clinical research. OBJECTIVE To identify the factors determining a patient's recovery after conservative treatment of compression fractures of the thoracolumbar spine. SUMMARY OF BACKGROUND DATA The reported results of compression fractures are poor. These results are not influenced by the severity of compression, the fracture site, or the residual deformity. Otherwise, the factors that determine a patient's recovery are unknown. METHODS In 48 conservatively treated patients the preinjury versus the 12-month follow-up differences (Δ) in back pain (visual analogue scale for pain), Oswestry disability index (ODI), and the Greenough and Fraser low back outcome scale were prospectively recorded. For these differences and for time lost from work and satisfaction, multiple linear regressions with combinations of 16 factors were performed. RESULTS At 1 year, patients with an income-insurance were 9% (P = 0.096) more disabled than those without. They reported a 15% less favorable global outcome and 27% less participation. Smokers were 13% (P = 0.010) more disabled and 11% (P = 0.044) less satisfied. With each increase of the AO-fracture type from A1 to A3 the disability was 8% worse. Patients with pre-existent chronic low back pain (CLBP) returned two points (on a visual analogue scale [VAS] pain total of 10) more closely (P = 0.041) to their preinjury pain level than those without but were 21% (P = 0.001) less satisfied. Our model offers an explanation for more than 25% of the variability of ΔODI and of the satisfaction. For sick leave, no significant predictors were found. CONCLUSION Smoking and insurance status are the strongest negative predictors for recovery. LBP patients returned more closely to their preinjury back pain level, but were less satisfied. The AO fracture type had a marked influence on disability, the sagittal deformity had not. The time lost from work did not depend on patient or injury-related factors. LEVEL OF EVIDENCE N/A.

Abstract
STUDY DESIGN Retrospective analysis of 16 patients. SUMMARY OF BACKGROUND DATA The lumbar split fracture-dislocation is a rare but severe injury, which is type C1.2.1 fracture in the Association for the Study of Internal Fixation spine fracture classification. The axial compressive and torsional force shattered the vertebral body into 2 halves and displaced them rotationally. This kind of fracture is so highly unstable that the treatment is very challenging. PURPOSE The purpose of this study was to report and compare on clinical outcome and complications of patients with lumbar split fracture-dislocation which had been treated either short-segment or long-segment posterior fixation and anterior fusion. MATERIALS AND METHODS A total of 16 patients with acute, split fracture-dislocation of the lumbar spine from March 2000 to May 2009 in our department were recruited. Seven patients (group I) treated by long-segment posterior fixation (2 levels above and 2 below the fracture) and anterior corpectomy and strut grafting. With the improvement of surgical technique and instrument, 9 patients after August 2004 were treated by short-segment posterior fixation (1 level above and 1 below, and included the fractured vertebrae itself) and anterior discectomy and strut grafting. The intraoperative blood loss, operation time, complications of operation, time to achieve bony fusion, Frankel scale, Oswestry Disability index, and Visual Analogue Pain Scale the Cobb angle were collected and compared. RESULTS The mean follow-up was 33.4 months for group I and 36.2 months for group II. The operation time was 457.1 minutes in group I which was significantly longer than 240.0 minutes in group II. The total blood loss was for group I was 2001.4 mL (range, 1580-2500 mL) and for group II was 730.6 mL (range, 430-950 mL). There was no neurological deterioration after surgery in both group and no difference in neurological outcome between the 2 groups. The loss of correction in Cobb angle averaged at the final evaluation was 2 and 5 degrees for groups I and II, respectively. There was no radiologically visible pseudarthrosis. The postoperative Visual Analogue Pain Scale score was 3.3 and 2.7 for groups I and II, respectively. In the SF-36 survey, after surgery the domains Role physical and Bodily pain improved significantly only in group B (P<0.05 and P=0.06, respectively). Time to achieve bony fusion in group I was 7.9 months which was significantly longer than 3.8 months in group II. Complications included 3 urinary infections, 1 decubitus ulcer, and 1 superficial infection that were cured by antibiotics. Screw breakage was found in 1 patient in the group II. CONCLUSIONS The lumbar sagittal split fracture-dislocation is a rare but severe injury, which can be treated either with short-segment or long-segment posterior fixation and anterior fusion. The short construct with pedicle screws in the fractured vertebrae followed by the maneuver of rod derotation can obtain anatomic reduction, restoration of 3-column alignment, and decompress the affected neural elements by restoration of the normal canal dimension. It may be a better therapeutic option for the highly unstable lumbar fracture of C1.2.1.

Abstract
Study Design Cohort study. Purpose The aim of this study is to propose and evaluate a new technique to assess bone mineral density of fractured vertebrae using quantitative computed tomography (QCT). Overview of Literature There is no available technique to estimate bone mineral density (BMD) at the fractured vertebra because of the alterations in bony structures at the fracture site. Methods Forty patients with isolated fracture from T10 to L2 were analyzed from the vertebrae above and below the fracture level. Apparent density (AD) was measured based on the relationship between QCT images attenuation coefficients and the density of calibration objects. AD of 8 independent regions of interest (ROI) within the vertebral body and 2 ROI within the pedicles of vertebrae above and below the fractured vertebra were measured. At the level of the fractured vertebra, AD was measured at the pedicles, which are typically intact. AD of the fractured vertebral body was linearly interpolated, based on the assumption that AD at the fractured vertebra is equivalent to the average AD measured in vertebrae adjacent to the fracture. Estimated and measured AD of the pedicles at the fractured level were compared to verify our assumption of linear interpolation from adjacent vertebrae. Results The difference between the measured and the interpolated density of the pedicles at the fractured vertebra was 0.006 and 0.003 g/cm3 for right and left pedicle respectively. The highest mean AD located at the pedicles and the lowest mean AD was found at the anterior ROI of the vertebral body. Significant negative correlation exist between age and AD of ROI in the vertebral body. Conclusions This study suggests that the proposed technique is adequate to estimate the AD of a fractured vertebra from the density of adjacent vertebrae.

Abstract
INTRODUCTION A case of young male patients aged 25 years old presented with history of injured from falling heavy object on his back. There was burst Fracture of L5 Vertebrae with grade 3 spondylolisthesis. It was completely different from the types of L5 fracture that had been published up to now. Our patient had combination of a complete burst fracture of the fifth lumbar vertebra with dislocation and complete disruption of the posterior ligamantous and bony complex between L5 and sacrum. We would like to report this unique case of comminuted burst fracture of L5 with grade III spondylolisthesis treated with reconstruction of L5 body from transforaminol approach with the good results & significant neurological improvement till his six month follow up after the operation. CASE REPORT A case of young male patients aged 25 years old presented with history injured from falling heavy object on his back. The physical examination revealed contusion on his back Neurological examination confirmed complete paralysis of L5 and S1 root on both sides. Loss Bladder-bowel function, sphincter tone and peri-anal sensation. Plain radiograph of lumbar-sacral spine showed the anterior dislocation of L5-S1 spondylo-listhesis approximately 75%, with the complete comminuted burst fracture of L5 vertebra. CONCLUSION Anterior support and reconstruction of vertebral body is of immense importance in Lumbar burst fracture, When combined with posterior short segment fixation. This can be achieved with Usage of expandable cages when opted for posterior only approach. They obviate need of anterior approach for reconstruction of vertebral body.

Abstract
Objective To illustrate the technique of single-stage posterior subtotal corpectomy and circumferential reconstruction for the treatment of unstable thoracolumbar burst fractures and to evaluate the radiographical and clinical outcomes of patients treated using this technique. Methods 16 consecutive patients with unstable thoracolumbar burst fractures were treated with single-stage posterior subtotal corpectomy and circumferential reconstruction. The mean patient age was 54.8 years. The mean follower up period was 25 months. Five patients suffered from T12 fractures, 10 from L1, 1 from L2. The segmental kyphosis, neurologic status, visual analogue scale for back pain was evaluated before surgery and at follow up. Results The segmental kyphotic angle improved from 18.5 degrees before surgery to -9.2 degrees at the last follow up. The mean correction angle was 28.9 degrees. The mean surgical time was 255 minutes, and a mean intraoperative blood loss was 1073 mL. Intraoperative complications included two dural tears, and a superficial wound infection. There were no other severe complications. The mean visual analog scale of back pain decreased from a mean value of 6.6 to 2 at the last follow up. Conclusion The single-stage posterior subtotal corpectomy and circumferential reconstruction achieved satisfactory kyphosis correction with direct visualization of the circumferentially decompressed spinal cord, as well as good fusion with less blood loss and complications. It is a safe and reliable surgical treatment option for unstable thoracolumbar burst fractures.

Abstract
PURPOSE The purpose of this study was in thoracolumbar fractures to assess the effectiveness of minimal invasive stabilisation compared to the open technique with regards to the change in kyphosis angle, the loss of reduction and length of hospital stay. METHODS The retrospective study consisted of 104 patients who received minimally invasive stabilisation or open stabilisation. Patients were between 15 and 86 years of age, had a thoracolumbar fracture and no neurological deficits. Kyphotic angle (Cobb angle) and loss of reduction was compared after minimal invasive and open stabilisation. The Cobb angle was evaluated directly post operatively, at 6 weeks, 3 months, 6 months and 12 months after surgery. RESULTS Evaluated patients who received the minimally invasive technique had a shorter surgical intervention time and a shorter hospital stay compared to patients who received the open technique. Kyphosis angle and loss of reduction showed no significant difference compared to open technique. There was also no significant difference between minimally invasive poly-axial and mono-axial stabilisation. CONCLUSION In this study we provide evidence that MIS instrumentation in selected thoracolumbar fractures can effectively be used without significant differences in loss of reduction compared to open stabilisation. MIS can also sufficiently retain reduction as compared to traditional open techniques. The main advantages are reduced operation time and shorter hospital stay.

Abstract
The optimal treatment for thoracolumbar fractures (TLF) without neurological deficit remains controversial. Majority of the systematic reviews and meta-analyses have evaluated open operative approaches but have yet to compare the outcomes of minimally invasive percutaneous pedicle fixation (MIPPF) versus non-operative treatment. A retrospective cohort study was performed to compare clinical and radiological outcomes between MIPPF and conservative groups for TLF AO Type A1 to Type B2 during a 2-year follow-up period. Pre-operative plain and CT films were evaluated and decision made for short segment (non-fusion) MIPPF. Patients who refused operation were treated conservatively with three months of body cast, brace, or corset. MIPPF group showed earlier Visual Analog Score(VAS) improvement at six months post-injury (0 vs 6.0- p<0.001), as well as better functional and radiological outcomes (p<0.050) at final follow-up. Progressions of regional kyphosis (RK) were noted in both groups but there was no significant difference within and between them(p>0.050). MIPPF as a method of internal bracing can be pursued in the treatment of TLF, with larger future cohorts and RCTs being called for to support and explore new findings.

Abstract
As a result of axial compression, traumatic vertebral burst fractures disrupt the anterior column, leading to segmental instability and cord compression. In situations with diminished anterior column support, pedicle screw fixation alone may lead to delayed kyphosis, nonunion, and hardware failure. Vertebroplasty and kyphoplasty (balloon-assisted vertebroplasty) have been used in an effort to provide anterior column support in traumatic burst fractures. Cited advantages are providing immediate stability, improving pain, and reducing hardware malfunction. When used in isolation or in combination with posterior instrumentation, these techniques theoretically allow for improved fracture reduction and maintenance of spinal alignment while avoiding the complications and morbidity of anterior approaches. Complications associated with cement use (leakage, systemic effects) are similar to those seen in the treatment of osteoporotic compression fractures; however, extreme caution must be used in fractures with a disrupted posterior wall.

[PMID: 25596983 DOI: 10.1016/j.otsr.2014.11.012] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2014] [Revised: 10/20/2014] [Accepted: 11/17/2014] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Recent epidemiological data for spinal trauma in France are sparse. However, increased knowledge of sagittal balance and the development of minimally invasive techniques have greatly improved surgical management. OBJECTIVES To describe the epidemiology and management of traumatic vertebral fracture, and to analyze evolution and risk factors for poor functional outcome at 1 year's follow-up. MATERIALS AND METHODS A prospective multicenter French cohort study was performed over a 6-month period in 2011, including all cases of vertebral fracture surgery. Data were collected by online questionnaire over the Internet. Demographic characteristics, lesion type and surgical procedures were collected. Clinical, functional and radiological assessment was carried out at 1 year. RESULTS Five hundred and eighteen patients, with a mean age of 47 years, were included. Sixty-seven percent of fractures involved the thoracic or lumbar segment. Thirty percent of patients had multiple fractures and 28% neurological impairment. A minimally invasive technique was performed in 20% of cases and neurological decompression in 25%. Dural tear was observed in 42 patients (8%). Seventy percent of patients were followed up at 1 year. Functionally, SF-36 scores decreased on all dimensions, significantly associated with age, persistent neurological deficit and previous spine imbalance. Thirty-eight percent of working patients had returned to work. Radiologically, sagittal balance was good in 74% of cases, with fracture consolidation in 70%. DISCUSSION Despite progress in management, spinal trauma was still a source of significant morbidity in 2011, with pronounced decrease in quality of life. Conserved sagittal balance appeared to be associated with better functional outcome.

Injury 2015; 46:392-8.

Abstract
INTRODUCTION The purpose of this study was to determine whether radiographic findings associated with thoracolumbar burst fractures could also indicate the presence of posterior ligamentous complex (PLC) injuries, which were identified through short-tau inversion-recovery (STIR)-weighted MRI. PATIENTS AND METHOD Sixty-four patients were surgically treated for thoracolumbar burst fractures between April 2007 and February 2014 at our institution. Twenty-four patients were excluded from this study because of the lack of STIR-weighted MRIs, and therefore 40 patients were included in this study. The patients were divided into two groups based upon the integrity of the PLC, which was evaluated using STIR-weighted MRI: a P group with a PLC injury and a C group without such injury. The following radiographic parameters were evaluated: loss of vertebral body height (LOVBH), local kyphosis (LK), vertebral body translation, canal compromise (sagittal transverse ratio, STR), interlaminar distance (ISD), supraspinous distance (SSD) and interspinous distance (ISD). Frankel scale score and total severity score (load sharing and thoracolumbar injury classification systems, respectively) were also evaluated. RESULTS Preoperative STIR-weighted MRI showed that 25 patients had a PLC injury (P group: 15 men and 10 women), and 15 patients did not have a PLC injury (C group: 8 men and 7 women). More patients in the P group had an LK>20°: 14 patients in the P group and 1 patient in the C group (p<0.01). The % SSD differed between the P and C groups (118.8%±53.4% and 88.0%±24.3%, respectively; p<0.05). Multivariate logistic analysis showed that an LK>20° was a risk factor for PLC injury in patients with thoracolumbar burst fractures (odds ratio, 55.5 [95% confidence interval, 1.30-2360.1]; p<0.05). CONCLUSIONS These results demonstrate that while LOVBH, vertebral body translation, and canal compromise do not correlate significantly with the presence of a PLC injury in patients with thoracolumbar fractures, an LK>20° and increased % SSD are associated with a PLC injury.

Expectations of recovery and functional outcomes following thoracolumbar trauma: an evidence-based medicine process to determine what surgeons should be telling their patients. J Neurosurg Spine 2014; 22:101-11.

Abstract
OBJECT The aim of this study was to define the expected functional and health-related quality of life outcomes following common thoracolumbar injuries on the basis of consensus expert opinion and the best available literature. Patient expectations are primarily determined by the information provided by health care professionals, and these expectations have been shown to influence outcome in various medical and surgical conditions. This paper presents Part 2 of a multiphase study designed to investigate the impact of patient expectations on outcomes following spinal injury. Part 1 demonstrated substantial variability in the information surgeons are communicating to patients. Defining the expected outcomes following thoracolumbar injury would allow further analysis of this relationship and enable surgeons to more accurately and consistently inform patients. METHODS Expert opinion was assembled by distributing questionnaires comprising 4 cases representative of common thoracolumbar injuries to members of the Spine Trauma Study Group (STSG). The 4 cases included a thoracolumbar junction burst fracture treated nonoperatively or with posterior transpedicular instrumentation, a low lumbar (L-4) burst fracture treated nonoperatively, and a thoracolumbar junction flexion-distraction injury managed with posterior fusion. For each case, 5 questions about expected outcomes were posed. The questions related to the proportion of patients who are pain free, the proportion who have regained full range of motion, and the patients' recreational activity restrictions and personal care and social life limitations, all at 1 year following injury, as well as the timing of return to work and length of hospital stay. Responses were analyzed and combined with the results of a systematic literature review on the same injuries to define the expected outcomes. RESULTS The literature review identified 38 appropriate studies that met the preset inclusion criteria. Published data were available for all injuries, but not all outcomes were available for each type of injury. The survey was completed by 31 (57%) of 53 surgeons representing 24 trauma centers across North America (15), Europe (5), India (1), Mexico (1), Japan (1) and Israel (1). Consensus expert opinion supplemented the available literature and was used exclusively when published data were lacking. For example, 1 year following cast or brace treatment of a thoracolumbar burst fracture, the expected outcomes include a 40% chance of being pain free, a 70% chance of regaining pre-injury range of motion, and an expected ability to participate in high-impact exercise and contact sport with no or minimal limitation. Consensus expert opinion predicts reemployment within 4-6 months. The length of inpatient stay averages 4-5 days. CONCLUSIONS This synthesis of the best available literature and consensus opinion of surgeons with extensive clinical experience in spine trauma reflects the optimal methodology for determining functional prognosis after thoracolumbar trauma. By providing consistent, accurate information surgeons will help patients develop realistic expectations and potentially optimize outcomes.

Abstract
PURPOSE The aim of the study is to use an algorithm previously published to decide whether to perform open surgery or percutaneous surgery with short fixation in patients with thoraco-lumbar junction and lumbar spine fractures, and to compare retrospectively surgical and conservative options of treatment. METHODS Between 2005 and 2009, two groups of 25 patients were analyzed to compare retrospectively surgical and conservative option of treatment to assess perception of pain and to evaluate quality of life during treatment, to evaluate how quickly patients return to work and to their daily activities, to evaluate patients' satisfaction. X-ray controls were performed to evaluate the fusion rate at 3 and 6 months and CT scans at 6 months. RESULTS The surgical group had a better functional recovery, a better quality of life and returned to work earlier in comparison to the conservative group. CONCLUSIONS We can conclude that the percutaneous procedure seems to give better results in terms of satisfaction and return to normal activities, although both procedures guarantee excellent fusion rates.

Abstract
Study Design Retrospective analysis. Purpose The aim of this study was to evaluate the clinical and radiological outcomes of patients with unstable thoracolumbar fracture (UTLF) who were treated by percutaneous long-segmental posterior fixation (PLSPF) by two vertebrae cranial to the fracture with two vertebrae caudal. Overview of Literature To the best of our knowledge, PLSPF for stabilization of UTLF has not been reported. Methods The study involved retrospective analysis and investigation from the results of 27 patients who had undergone PLSPF for stabilization of a UTLF with partial neurologic deficit, over a follow-up period of two years. Kyphotic angle (KA), anterior vertebral height percentage (AVHP) and cross-sectional ratio of the displaced fragment within the spinal canal were evaluated with simple radiographs and axial computed tomography scans preoperatively and two years postoperatively. The clinical outcome for pain was assessed by a visual analogue scale (VAS) and Denis' scale, and the degree of neurologic deficit was measured by modified Frankel classification. Results Five patients had minor complications. The KA, AVHP, and cross-sectional ratio of the displaced fragment improved significantly after surgery (p<0.001, p<0.001, p<0.003, respectively). Neurologic recovery of one or more for the Frankel grade was seen in 19 patients with an average improvement of 1.7. The VAS and Denis' score improved significantly at a two year follow-up (p=0.02, p=0.012, respectively). Conclusions The technique of PLSPF is useful for the treatment of UTLF with partial neurologic deficit, and produces decreased morbidity and fewer complications.

Abstract
STUDY DESIGN A retrospective review of clinical and radiological parameters. OBJECTIVE The purpose of this study was to investigate the therapeutic efficacy of transpedicular intracorporeal bone graft (IBG) in osteonecrosis of vertebral body (ONV) for 5-years follow-up period. SUMMARY OF BACKGROUND DATA Although a broad spectrum of surgical options has been described for the treatment of ONV without neurological deficits, no effective treatment has been definitely established. Limited previous work has reported favorable outcomes with IBG; however, these studies were limited by short-term follow-up and small sample sizes. This study is the first to report the clinical and radiological results of IBG with short-segmental posterior instrumentation in ONV with a 5-year follow-up period. METHODS Thirty-six patients were followed for at least 5 years after transpedicular IBG with short-segmental posterior instrumentation. We retrospectively reviewed outcomes, including visual analogue scale score, the Oswestry Disability Index score, compression ratio, and kyphotic angle. RESULTS There were 11 complications, including pneumonia in 4 patients, screw loosening in 5 patients, mild hematoma at the subcutaneous tissue in 1 case, and pseudarthrosis in 1 case. The mean visual analogue scale score was exhibiting V-shaped upward trend after postoperative 6 months that ended with the almost similar score obtained with preoperative status. The mean Oswestry Disability Index score was also shown with similar trend. In functional score, there was a statistical significant improvement until only 6 months after surgery. In radiological evaluation, the mean kyphotic angle and compression ratio was significantly corrected after surgery (P < 0.05). However, these improved radiological parameters were maximal at the immediate postoperative time with gradual loss over time. CONCLUSION Transpedicular IBG with short-segmental posterior instrumentation may lead to complications such as prolonged back pain and recurrence of kyphotic deformity in the 5 years after the procedure. Therefore, we do not recommend short-segmental posterior instrumentation concurrently with transpedicular IBG for treating ONV. LEVEL OF EVIDENCE 4.

Abstract
BACKGROUND AND PURPOSE Thoracoscopic-assisted ventral stabilisation for thoracolumbar fractures has been shown to be associated with decreased recovery time and less morbidity when compared with open procedures. However, there are a limited number of studies evaluating late clinical and radiological results after thoracoscopic spinal surgery. METHODS We performed an analysis of the late outcomes of thoracolumbar fractures after minimally invasive thoracoscopic ventral instrumentation. Between August 2003 and December 2008, 70 patients with thoracolumbar fractures (T5-L2) underwent ventral thoracoscopic stabilisation. Tricortical bone grafts, anterior plating systems (MACS-System), and cage implants were used for stabilisation. Outcomes measured include radiologic images (superior inferior endplate angle), Visual Analogue Scale (VAS), VAS Spine Score, quality of life scores SF-36 and Oswestry Disability Index (ODI). RESULTS Forty seven patients (67%, 47 out of 70) were recruited for the follow up evaluation (2.2 ± 1.5 years). Lower VAS Spine scores were calculated in patients with intra- or postoperative complications (44.7 (± 16.7) vs. 65.8 (± 24.5), p=0.0447). There was no difference in outcome between patients treated with bone graft vs. cage implants. Loss of correction was observed in both bone graft and titanium cage groups. INTERPRETATION The present study demonstrates diminished long-term quality of life in patients treated with thoracoscopic ventral spine when compared with the outcome of german reference population. In contrast to the other patients, those patients without intra-operative or post-operative complications were associated with improved outcome. The stabilisation method (bone graft versus spinal cage) did not affect the long-term clinical or radiographic results in this series.

Abstract
BACKGROUND Decision-making regarding nonoperative versus operative treatment of patients with thoracolumbar burst fractures in the absence of neurologic deficits is controversial. Lack of evidence-based practice may result in patients being treated inappropriately and being exposed to unnecessary adverse consequences. PURPOSE Using meta-analysis, we therefore compared pain (VAS) and function (Roland Morris Disability Questionnaire) in patients with thoracolumbar burst fractures without neurologic deficit treated nonoperatively and operatively. Secondary outcomes included return to work, radiographic progression of kyphosis, radiographic progression of spinal canal stenosis, complications, cost, and length of hospitalization. METHODS We searched MEDLINE, EMBASE(®), and the Cochrane Central Register of Controlled Trials for 'thoracic fractures', 'lumbar fractures', 'non-operative', 'operative' and 'controlled clinical trials'. We established five criteria for inclusion. Data extraction and quality assessment were in accordance with Cochrane Collaboration guidelines. The main analyses were performed on individual patient data from randomized controlled trials. Sensitivity analyses were performed on VAS pain, Roland Morris Disability Questionnaire score, kyphosis, and return to work, including data from nonrandomized controlled trials and using fixed effects meta-analysis. We identified four trials, including two randomized controlled trials consisting of 79 patients (41 with operative treatment and 38 with nonoperative treatment). The mean followups ranged from 24 to 118 months. RESULTS We found no between-group differences in baseline pain, kyphosis, and Roland Morris Disability Questionnaire scores. At last followup, there were no between-group differences in pain, Roland Morris Disability Questionnaire scores, and return to work rates. We found an improvement in kyphosis ranging from means of 12.8º to 11º in the operative group, but surgery was associated with higher complication rates and costs. CONCLUSIONS Operative management of thoracolumbar burst fractures without neurologic deficit may improve residual kyphosis, but does not appear to improve pain or function at an average of 4 years after injury and is associated with higher complication rates and costs. LEVEL OF EVIDENCE Level II, therapeutic study. See the Guidelines for Authors for a complete description of level of evidence.

Abstract
BACKGROUND The main indications for surgery for old thoracolumbar fractures are pain, progressive deformity, neurological damage, or increasing neurological deficit. These fractures have been one of the greatest therapeutic challenges in spinal surgery. Anterior, posterior, or combined anterior and posterior procedures have been successful to some extent. As far as we know, there is no report in the literature of transforaminal lumbar interbody fusion (TLIF) for old thoracolumbar fracture and dislocation. METHODS Case report. RESULTS A 26-year-old man with old fracture and dislocation of T12/L1 was treated with TLIF. At 12 months' follow-up, multi-slice computed tomography (CT) scans showed that solid fusion had been achieved between T12 and L1. Back pain had resolved completely at 2-year follow-up. CONCLUSIONS We performed TLIF for in a man with old fracture and dislocation of T12/L1, with good clinical outcome. TLIF might be an option in the treatment of old thoracolumbar fracture.

Thoracolumbar burst fractures with a neurological deficit treated with posterior decompression and interlaminar fusion. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2011; 20:2195-201. [PMID: 21688000 DOI: 10.1007/s00586-011-1875-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/08/2010] [Revised: 03/07/2011] [Accepted: 06/04/2011] [Indexed: 10/18/2022]
Abstract
INTRODUCTION To our knowledge, thoracolumbar burst fractures with a neurological deficit treated with posterior decompression and interlaminar fusion have never been reported. Our study was to assess the outcome of posterior decompression and interlaminar fusion in treating thoracolumbar burst fractures with a neurological deficit. MATERIALS AND METHODS Forty-one patients suffering from thoracolumbar burst fractures with a neurological deficit were included this study. All patients were treated with posterior decompression, interlaminar fusion and short-segment fixation of the vertebrae above and below the fracture level and the fractured vertebrae. RESULTS All patients were followed up for at least 24 months after surgery. Operative time and blood loss averaged 72 min and 325 ml, respectively. Thirty-eight patients with incomplete neurological lesions improved, by at least one American Spine Injury Association grade, whereas no neurological deterioration was observed in any case. Overall sagittal alignment improved from an average preoperative 22.4°-4.6° kyphosis at the final follow-up observation. The anterior vertebral body height ratio improved from 0.61 before surgery to 0.90 after surgery, whereas posterior vertebral body height ratio improved from 0.90 to 0.95. Spinal canal encroachment was reduced from an average 61.5% before surgery to 8.7% after surgery. Interlaminar radiological fusion was achieved within 6-8 months after surgery. No instrumentation failure was found in any patients. CONCLUSION Posterior decompression, interlaminar fusion with posterior short-segment fixation provided excellent immediate reduction for traumatic segmental kyphosis and significant spinal canal clearance, and restored vertebral body height in the fracture level in patients with a thoracolumbar burst fracture and associated neurological deficit.

Abstract
INTRODUCTION Although outcome instruments have been used extensively in spine surgical research, few studies at present specifically address their use in investigations regarding spine trauma. In this review we provide a summary of the outcome instruments used most frequently in spine trauma research, identify the unique challenges of studying outcomes of spine trauma patients, and propose an integrated approach that may be beneficial for future studies. METHODS We reviewed the use of outcome instruments applicable to spine trauma research, including generic health measures, inventories of back-specific function, pain scales, health related quality of life (HRQOL) instruments, and radiographic determinants of outcome. RESULTS Several inventories have been utilised to measure clinical outcomes following spinal trauma. Excluding measures of neurological function (e.g. ASIA motor score), none have been specifically validated for use with spine fractures. The SF-36, RMDQ, and ODI are amongst the most commonly used instruments. Importantly, the use of validated functional outcome measures in spine trauma research is hampered by the fact that the pre-morbid state of patients who sustain spine trauma may not be accurately represented by normative values established for the general population. The VAS is used most frequently to assess degree of neck and back pain. Most studies have relied on non-validated measures to determine radiographic results of treatment, although more elegant radiographic metrics exist. CONCLUSIONS Functional outcome measurement of traumatically injured spine patients is challenging because available generic and spine-specific instruments were not designed for or validated in this population. Furthermore, no single inventory is capable of capturing global data necessary to evaluate results following these injuries. Investigations seeking to quantify outcomes following spine trauma should consider the use of a combination of existing surveys in a complementary fashion that should include a generic health survey, a measure of back-specific function, and determinants of bodily pain and work-related disability.

Abstract
OBJECTIVO: Avaliação dos resultados clínicos e radiográficos do tratamento cirúrgico de fracturas tipo burst da coluna toracolombar por fixação posterior curta, com instrumentação do nível fracturado e moldagem in situ. MÉTODOS: Entre Novembro de 2007 e Janeiro de 2009, foram seleccionados pacientes que sofreram fractura da coluna toracolombar tipo burst a um nível, com presença de instabilidade neurológica ou mecânica, submetidos a fixação posterior curta com instrumentação do nível fracturado e moldagem in situ. Foi realizada avaliação radiográfica e clínica no pré-operatório, no pós-operatório imediato e, pelo menos, um ano após a cirurgia. RESULTADOS: Foram incluídos 12 pacientes com uma média de idades de 39,1 anos. O seguimento médio foi de 14,5 meses. Um paciente abandonou a consulta aos dois meses, e dois não compareceram à consulta de avaliação clínica. Dois pacientes apresentavam défices neurológicos à entrada (Frankel B). Obtivemos uma melhoria da angulação vertebral de 14,2º, da deformidade cifótica de 11,2º e 27,2% de recuperação da altura vertebral anterior. Ao tempo de seguimento final, verificaram-se perdas de 2,7º, 3,8º e 6,1%, respectivamente. Registou-se um Oswestry Disability Index (ODI) médio de 6,2 e uma Visual Analogic Scale (VAS) de 1,6. Os dois pacientes com lesões neurológicas melhoraram para um nível D de Frankel. Não se observou qualquer caso de desmontagem ou falência do material. CONCLUSÕES: A instrumentação do nível da fractura aumenta a rigidez da montagem, protegendo a vértebra fracturada de cargas anteriores, garantindo um ponto de fixação adicional que permite uma melhor correcção por moldagem in situ. Os resultados obtidos, radiográficos e clínicos, são bons e mantêm-se ao longo do tempo.

Abstract
STUDY DESIGN A prospective study was performed. OBJECTIVE To assess a technique, three-column reconstruction through single posterior (TRSP) approach, in treatment of highly unstable thoracolumbar fracture. SUMMARY OF BACKGROUND DATA The goal of surgical intervention for treatment of unstable thoracolumbar fractures is to decompress the neural elements, restore vertebral body height, correct angular deformity, and stabilize the columns of the spine. Operative approaches remain disputed. Common opinions include short-segment posterior fixation, multiple-segment posterior fixation, stand-alone anterior approach fixation, and combined anterior-posterior approach. Each technique has its advantages and disadvantages. METHODS A consecutive series of 37 thoracolumbar fractures with load sharing scores > or =6 were managed with TRSP between May 2004 and September 2006. All patients were observed up for a minimum of 2 years. Demographic data, neurologic status, segmental kyphosis, segmental height, the fracture severity score, Visual Analogue Scale, and treatment-related complications were evaluated. RESULTS The mean operative time was 157 minutes (range, 120-240). The mean blood loss was 1086 mL (range, 700-3100). Averagely Frankel score improved from 3.46 to 4.46; kyphotic angulation improved from 25.75 degrees before surgery to 4.49 degrees at last follow-up, and the loss of segmental height improved from a mean of 35.22% before surgery to 7.01% at the time of the last follow-up. The mean preoperative Visual Analogue Scale score was 7.92, and most patients had no complain of pain at last follow-up. No patient experienced worsening of neurologic deficits and other severe complications at last follow-up. One patient developed titanium mess cage subsidence, but revision was not necessary. CONCLUSION The technique of TRSP approach is safe, effective, and offers some advantages over the classic posterior, anterior, combined anterior-posterior approach for some specific highly unstable thoracolumbar fractures.

Abstract
STUDY DESIGN A systematic quantitative review of the literature. OBJECTIVE To compare combined anterior-posterior surgery versus posterior surgery for thoracolumbar fractures in order to identify better treatments. SUMMARY OF BACKGROUND DATA Axial load of the anterior and middle column of the spine can lead to a burst fracture in the vertebral body. The management of thoracolumbar burst fractures remains controversial. The goals of operative treatment are fracture reduction, fixation and decompressing the neural canal. For this, different operative methods are developed, for instance, the posterior and the combined anterior-posterior approach. Recent systematic qualitative reviews comparing these methods are lacking. METHODS We conducted an electronic search of MEDLINE, EMBASE, LILACS and the Cochrane Central Register for Controlled Trials. RESULTS Five observational comparative studies and no randomized clinical trials comparing the combined anteriorposterior approach with the posterior approach were retrieved. The total enrollment of patients in these studies was 755 patients. The results were expressed as relative risk (RR) for dichotomous outcomes and weighted mean difference (WMD) for continuous outcomes with 95% confidence intervals (CI). CONCLUSIONS A small significantly higher kyphotic correction and improvement of vertebral height (sagittal index) observed for the combined anterior-posterior group is cancelled out by more blood loss, longer operation time, longer hospital stay, higher costs and a possible higher intra- and postoperative complication rate requiring re-operation and the possibility of a worsened Hannover spine score. The surgeons' choices regarding the operative approach are biased: worse cases tended to undergo the combined anterior-posterior approach.

Abstract
PURPOSE Surgical treatment in the case of thoracolumbar burst fractures is very controversial. Posterior instrumentation is most frequently used, however, but the number of levels to be instrumented still remains a matter of debate. MATERIALS AND METHODS A total of 94 patients who had a single burst fracture between T11 and L2 were selected and were managed using posterior instrumentation with anterior fusion when necessary. They were divided into three groups as follows; Group I (n = 28) included patients who were operated by intermediate segment fixation, Group II (n = 32) included patients operated by long segment fixation, and Group III (n = 34) included those operated by intermediate segment fixation with a pair of additional screws in the fractured vertebra. The mean follow-up period was twenty one months. The outcomes were analyzed in terms of kyphosis angle (KA), regional kyphosis angle (RA), sagittal index (SI), anterior height compression rate, Frankel classification, and Oswestry Disability Index questionnaire. RESULTS In Groups II and III, the correction values of KA, RA, and SI were much better than in Group I. At the final follow up, the correction values of KA (6.3 and 12.1, respectively) and SI (6.2 and 12.0, respectively) were in Groups II and III found to be better in the latter. CONCLUSION The intermediate segment fixation with an additional pair of screws at the fracture level vertebra gives results that are comparable or even better than long segment fixation and gives an advantage of preserving an extra mobile segment.

Long-term investigation of nonsurgical treatment for thoracolumbar and lumbar burst fractures: an outcome analysis in sight of spinopelvic balance. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2008; 17:1073-95.

Abstract
The nonsurgical treatment of thoracolumbar (TLB) and lumbar burst (LB) fractures remains to be of interest, though it is not costly and avoids surgical risks. However, a subset of distinct burst fracture patterns tend to go with a suboptimal radiographic and clinical long-term outcome. Detailed fracture pattern and treatment-related results in terms of validated outcome measures are still lacking. In addition, there are controversial data on the impact of local posttraumatic kyphosis that is associated, in particular, with nonsurgical treatment. The assessment of global spinal balance following burst fractures has not been assesed, yet. Therefore, the current study intended to investigate the radiographical and clinical long-term outcome in neurologically intact patients with special focus on the impact of regional posttraumatic kyphosis, adjacent-level compensatoric mechanisms, and global spine balance on the clinical outcome. For the purpose of a homogenous sample, strong in- and exclusion criteria were applied that resulted in a final study sample of 21 patients with a mean follow-up of 9.5 years. Overall, clinical outcome evaluated by validated measures was diminished, with 62% showing a good or excellent outcome and 38% a moderate or poor outcome in terms of the Greenough Low Back Outcome Scale. Notably, vertebral comminution in terms of the load-sharing classification, posttraumatic kyphosis, and an overall decreased lumbopelvic lordosis showed a significant effect on clinical outcome. A global and segmental curve analysis of the spine T9 to S1 revealed significant alterations as compared to normals. But, the interdependence of spinopelvic parameters was not disrupted. The patients' spinal adaptability to compensate for the posttraumatic kyphotic deformity varied in the ranges dictated by pelvic geometry, in particular the pelvic incidence. The study substantiates the concept that surgical reconstruction and maintenance of a physiologically shaped spinal curve might be the appropriate treatment in the more severely crushed TLB and LB fractures.

Abstract
Minimally invasive surgery has become more and more important for the treatment of traumatic spine fractures. Besides, some clinical studies, objective data regarding the possible lower damage to the surrounding tissue of the spine is still missing. Here we report a sheep model where we compared a percutaneous versus an open approach for dorsal instrumentation with pedicle screws to the spine. Twelve skeletally mature sheep underwent bilateral pedicle screw fixation at the L4-L6 level. Forty-eight pedicle screws were bilaterally inserted into the pedicles and connected with rods using either an open dorsal standard or a percutaneous approach. Operation time, blood flow, compartment pressure, radiation time, loss of blood, laboratory findings and EMG were evaluated to objectify possible advantages for the percutaneous operation technique. Loss of blood and the distribution of CK-MM as a marker for muscle damage were significantly lower in the percutaneous group. However, radiation time was significantly longer in the percutaneous group. Other parameters like compartment pressure, blood flow and also measurement of the EMG at different time points did not reveal significant differences. Based on the results we found in the present study, percutaneous screw insertion can bring moderate advantages but it should be noted that essential functional deficits to the muscle could not be detected.

Abstract
Fractures of the thoracolumbar spine rank among the severest injuries of the human skeleton. Especially in younger patients they often result from high-energy accidents. Recently, a shift in paradigm towards more aggressive treatment strategies including anterior procedures could be observed. However, so far only few data exist reflecting the quality of life (QoL) after such injuries. The aim of this study was to evaluate medium-term QoL and further to identify factors that influence the clinical outcome in patients with fractures of the thoracolumbar spine. Data of 906 patients who were treated during a 10-year period in our institution were evaluated retrospectively. Only patients with single-level traumatic injuries aged between 18 and 65 years without neurological deficits, concomitant injuries of other locations and internal comorbidities were included into the investigation (n = 204). Three different treatment groups (i.e. non-operative, dorsal and dorsoventral stabilisation) were compared to healthy controls as well as different pain populations. The QoL was assessed using established questionnaires (SF-36, HFAQ, VAS-Spinescore, PRQ, and PTSD). Sixty-five percent of the included patients (n = 133) were studied at an average follow-up of 5.3 +/- 1.7 years after injury. All treatment groups revealed an identical gender and age distribution. More severe and unstable injuries were found in the surgical groups associated with higher treatment costs and a longer inability to work. Compared to healthy controls, QoL was compromised to the same extent in all groups. Furthermore, all patients treated in this study did significantly better than low back pain individuals with regard to QoL and pain regulation parameters. In our study, patients with thoracolumbar spine fractures showed a reduced QoL compared to healthy controls. Thus, patients do not seem to regain their former QoL. However, the level of discomfort was comparably low in all groups, even in patients with more severe injuries requiring extensive surgery. Overall, outcome and QoL after traumatic fractures of the thoracolumbar spine rather seem to be determined by the severity of injury than by pain regulation or other psychosocial factors which is likely the case in low back pain disorders.

Abstract
The treatment of thoracolumbar fractures remains controversial. A review of the literature showed that short-segment posterior fixation (SSPF) alone led to a high incidence of implant failure and correction loss. The aim of this retrospective study was to compare the outcomes of the SS- and long-segment posterior fixation (LSPF) in unstable thoracolumbar junction burst fractures (T12-L2) in Magerl Type A fractures. The patients were divided into two groups according to the number of instrumented levels. Group I included 32 patients treated by SSPF (four screws: one level above and below the fracture), and Group II included 31 patients treated by LSPF (eight screws: two levels above and below the fracture). Clinical outcomes and radiological parameters (sagittal index, SI; and canal compromise, CC) were compared according to demographic features, localizations, load-sharing classification (LSC) and Magerl subgroups, statistically. The fractures with more than 10 degrees correction loss at sagittal plane were analyzed in each group. The groups were similar with regard to age, gender, LSC, SI, and CC preoperatively. The mean follow-ups were similar for both groups, 36 and 33 months, respectively. In Group II, the correction values of SI, and CC were more significant than in Group I. More than 10 degrees correction loss occurred in six of the 32 fractures in Group I and in two of the 31 patients in Group II. SSPF was found inadequate in patients with high load sharing scores. Although radiological outcomes (SI and CC remodeling) were better in Group II for all fracture types and localizations, the clinical outcomes (according to Denis functional scores) were similar except Magerl type A33 fractures. We recommend that, especially in patients, who need more mobility, with LSC point 7 or less with Magerl Type A31 and A32 fractures (LSC point 6 or less in Magerl Type A3.3) without neurological deficit, SSPF achieves adequate fixation, without implant failure and correction loss. In Magerl Type A33 fractures with LSC point 7 or more (LSC points 8-9 in Magerl Type A31 and A32) without severe neurologic deficit, LSPF is more beneficial.

Abstract
Object
The purpose of this study was to evaluate the results obtained in patients who underwent anterior stabilization for three-column thoracolumbar fractures.
Methods
The authors retrospectively reviewed available clinical and radiographic data (1997–2006) to classify three-column thoracolumbar fractures according to the Association for the Study of Internal Fixation (AO) system, neurological status, spinal canal compromise, pre- and postoperative segmental angulation, and arthrodesis rate.
The mean computed tomography–measured preoperative spinal canal compromise was 48.3% (range 8–92%), and the mean vertebral body height loss was 39.4%. The mean preoperative kyphotic deformity of 14.9° improved to 4.6° at the final follow-up examination. Although this angulation had increased a mean of 1.8° during the follow-up period, the extent of correction was still significant compared with the preoperative angulation (p < 0.01). There were no cases of vascular complication or neurological deterioration.
Conclusions
Contemporary anterior spinal reconstruction techniques can allow certain types of unstable three-column thoracolumbar fractures to be treated via an anterior approach alone. Compared with traditional posterior approaches, the anterior route spares lumbar motion segments and obviates the need for harvesting of the iliac crest.

Abstract
ObjectDespite extensive published research on thoracolumbar burst fractures, controversy still surrounds which is the most appropriate treatment. The objective of this study was to evaluate the scientific literature on operative and nonoperative treatment of patients with thoracolumbar burst fractures and no neurological deficit.MethodsIn their search of the literature, the authors identified all possible relevant studies concerning thoracolumbar burst fracture without neurological deficit. Two independent observers performed study selection, methodological quality assessment, and data extraction in a blinded and objective manner for all papers identified during the search. In a synthesis of the literature, the authors obtained evidence for both operative and nonoperative treatments.ConclusionsThere is a lack of evidence demonstrating the superiority of one approach over the other as measured using generic and disease-specific health-related quality of life scales. There is no scientific evidence linking posttraumatic kyphosis to clinical outcomes. The authors found that there is a strong need for improved clinical research methodology to be applied to this patient population.

Abstract
The application of autogenous bone grafts represents the golden standard for reconstruction of the load-bearing anterior column in the thoracolumbar spine. However, the osseous integration of the implanted grafts is demanding and delayed union or pseudarthrosis may occur. There are no standardized data available yet indicating the further course in such cases. The aim of this study was to evaluate the incorporation of endoscopically applied grafts and to develop therapeutic strategies for delayed or non-fusions. Twenty patients suffering from unstable injuries of the thoracolumbar spine were studied in a prospective clinical trial. After primary dorsal stabilization, the anterior column was thoracoscopically reconstructed with an autogenous iliac crest graft and a fixed-angle implant (MACS). The osseous integration of the bone grafts was detected by MSCT 1 year postoperatively. Complete integration of the transplanted bone grafts was observed in only 65% of the cases. In 25% partial integration was detected and in two cases a fracture of the transplanted iliac crest graft occurred. Despite the incomplete integration of the bone grafts, the further course without surgical intervention revealed no clinical or radiological evidence of a concomitant implant loosening or a relevant secondary loss of correction. Similar to the open technique, endoscopic reconstruction of the anterior column with autogenous bone grafts may lead to disadvantageous results concerning the integration and healing of the applied bone grafts. Decision making in such cases depends on the individual clinical and radiological findings (i.e., evidence of implant loosening and concomitant loss of correction).
