Abstract
STUDY DESIGN Reliability study utilizing 183 injury CT scans by 22 spine trauma experts with assessment of radiographic features, classification of injuries and treatment recommendations. OBJECTIVES To assess the reliability of the AOSpine TL Injury Classification System (TLICS) including the categories within the classification and the M1 modifier. METHODS Kappa and Intraclass correlation coefficients were produced. Associations of various imaging characteristics (comminution, PLC status) and treatment recommendations were analyzed through regression analysis. Multivariable logistic regression modeling was used for making predictive algorithms. RESULTS Reliability of the AO Spine TLICS at differentiating A3 and A4 injuries (N = 71) (K = .466; 95% CI .458 - .474; P < .001) demonstrated moderate agreement. Similarly, the average intraclass correlation coefficient (ICC) amongst A3 and A4 injuries was excellent (ICC = .934; 95% CI .919 - .947; P < .001) and the ICC between individual measures was moderate (ICC = .403; 95% CI .351 - .461; P < .001). The overall agreement on the utilization of the M1 modifier amongst A3 and A4 injuries was fair (K = .161; 95% CI .151 - .171; P < .001). The ICC for PLC status in A3 and A4 injuries averaged across all measures was excellent (ICC = .936; 95% CI .922 - .949; P < .001). The M1 modifier suggests respondents are nearly 40% more confident that the PLC is injured amongst all injuries. The M1 modifier was employed at a higher frequency as injuries were classified higher in the classification system. CONCLUSIONS The reliability of surgeons differentiating between A3 and A4 injuries in the AOSpine TLICS is substantial and the utilization of the M1 modifier occurs more frequently with higher grades in the system.

Abstract
INTRODUCTION Although the reduction of traumatic fractures of the thoracolumbar spine is of good quality during conventional so-called open procedures, the alternative minimally invasive approach also appears to confer good results. The aim of this study was to measure the radiological parameters before and after minimally invasive surgery, in order to assess the quality of the reduction of thoracolumbar compression fractures. MATERIALS AND METHODS This retrospective, monocentric study included 112 patients with a mean age of 48.9years, presenting with 135 type A thoracolumbar compression fractures treated by a posterior minimally invasive surgical approach comprising vertebral augmentation or posterior osteosynthesis or a mixed procedure. RESULTS The parameters analyzed were significantly lower whatever the procedure in the immediate postoperative period. Mean regional and local kyphosis, posterior wall displacement, and mean vertebral height were significantly lower (p<0.01). Fracture reduction was better when osteosynthesis was associated with vertebral augmentation. In the osteosynthesis subgroup with osteosynthesis hardware removal but without vertebral augmentation, we found a significant worsening of the regional kyphosis (p<0.05). CONCLUSION The management of thoracolumbar compression fractures by a posterior minimally invasive approach allows excellent fracture reduction with a restoration of the spinal canal, vertebral height and kyphosis.

Abstract
BACKGROUND AND AIM Thoracic fractures can lead to death and disability. This retrospective study aimed to evaluate cases of upper and middle thoracic vertebral fractures due to trauma that had been treated, to determine the fracture type and treatment method according to age, sex, cause of injury, neurological status, fracture level, kyphotic angles, and classification methods and to discuss the results regarding that reported in the literature. PATIENTS AND METHODS This study included 238 patients who were evaluated for post-traumatic upper and middle thoracic vertebral fractures between January 2012 and December 2020. We classified each patient according to the Dennis, TLICS, ATLICS, and ASIA classifications using neurological examination, radiography, computed tomography, and magnetic resonance imaging. We statistically evaluated the data obtained. RESULTS Fifty-five percent of total patients were male. The average age was 51.11. Traffic accidents were the most common causes of trauma, with 67.2%. T8 was most affected. The ASIA classification, the Dennis, TLICS, and ATLICS classifications showed a significant increase in the severity of neurological deficits as the fracture scores increased (p < 0.001). We observed that the increase in the preoperative kyphotic angle caused an increase in the number of deficits according to the classifications (p < 0.001). CONCLUSION The ATLICS classification yielded more accurate results than that of the other classifications. In addition, the kyphotic angle was evaluated for upper and middle thoracic fractures, and we concluded it is important in surgical decision making.

Abstract
STUDY DESIGN Systematic review. OBJECTIVES Management of stable traumatic thoracolumbar burst fractures in neurologically-intact patients remains controversial. Conservative management fails in a subset of patients who require subsequent surgical fixation. The aim of this review is to (1) determine the rate of conservative management failure, and (2) analyze predictive factors at admission influencing conservative management failure. METHODS A systematic review adhering to PRISMA guidelines was performed. Studies with data pertaining to traumatic thoracolumbar burst fractures without posterior osteoligamentous injury (e.g. AO Type A3/A4) and/or the rate and predictive factors of conservative management failure were included. Risk of bias appraisal was performed. Pooled analysis of rates of failure was performed with qualitative analysis of predictors of conservative management failure. RESULTS 16 articles were included in this review (11 pertaining to rate of conservative management failure, 5 pertaining to predictive risk factors). Rate of failure of conservative management from a pooled analysis of 601 patients is 9.2% (95% CI: 4.5%-13.9%). Admission factors predictive of conservative management failure include age, greater initial kyphotic angle, greater initial interpedicular distance, smaller initial residual canal size, greater Load Sharing Classification (LSC) score and greater admission Visual Analog Scale (VAS) pain scores. CONCLUSION A proportion (9.2%) of conservatively managed, neurologically-intact thoracolumbar burst fractures fail conservative management. Among other factors, age, kyphotic angle, residual canal area and interpedicular distance should be investigated in prospective studies to identify the subset of patients prone to failure of conservative management. Surgical management should be carefully considered in patients with the above risk factors.

Patients with combined pelvic and spinal injuries have worse clinical and operative outcomes than patients with isolated pelvic injuries analysis of the German Pelvic Registry. BMC Musculoskelet Disord 2022; 23:251.

Abstract
Background Pelvic fractures are often associated with spine injury in polytrauma patients. This study aimed to determine whether concomitant spine injury influence the surgical outcome of pelvic fracture. Methods We performed a retrospective analysis of data of patients registered in the German Pelvic Registry between January 2003 and December 2017. Clinical characteristics, surgical parameters, and outcomes were compared between patients with isolated pelvic fracture (group A) and patients with pelvic fracture plus spine injury (group B). We also compared apart patients with isolated acetabular fracture (group C) versus patients with acetabular fracture plus spine injury (group D). Results Surgery for pelvic fracture was significantly more common in group B than in group A (38.3% vs. 36.6%; p = 0.0002), as also emergency pelvic stabilizations (9.5% vs. 6.7%; p < 0.0001). The mean time to emergency stabilization was longer in group B (137 ± 106 min vs. 113 ± 97 min; p < 0.0001), as well as the mean time until definitive stabilization of the pelvic fracture (7.3 ± 4 days vs. 5.4 ± 8.0 days; p = 0.147). The mean duration of treatment and the morbidity and mortality rates were all significantly higher in group B (p < 0.0001). Operation time was significantly shorter in group C than in group D (176 ± 81 min vs. 203 ± 119 min, p < 0.0001). Intraoperative blood loss was not significantly different between the two groups with acetabular injuries. Although preoperative acetabular fracture dislocation was slightly less common in group D, postoperative fracture dislocation was slightly more common. The distribution of Matta grades was significantly different between the two groups. Patients with isolated acetabular injuries were significantly less likely to have neurological deficit at discharge (94.5%; p < 0.0001). In-hospital complications were more common in patients with combined spine plus pelvic injuries (groups B and D) than in patients with isolated pelvic and acetabular injury (groups A and C). Conclusions Delaying definitive surgical treatment of pelvic fractures due to spinal cord injury appears to have a negative impact on the outcome of pelvic fractures, especially on the quality of reduction of acetabular fractures.

Abstract
Background and Objectives: The thoracolumbar burst fracture is one of the most common spinal injuries. If the patient has severe symptoms, corpectomy is indicated. Currently, minimally invasive corpectomy with a navigated expandable vertebral cage is available thanks to spinal surgical technology. The aim of this study is to retrospectively compare clinical and radiographic outcomes of conventional and navigational minimally invasive corpectomy techniques. Materials and Methods: We retrospectively evaluated 21 patients who underwent thoracolumbar minimally invasive corpectomy between October 2016 and January 2021. Eleven patients had a navigated expandable cage (group N) and 10 patients had a conventional expandable cage (group C). Mean follow-up period was 31.9 months for group N and 34.7 months for group C, ranging from 12 to 42 months in both groups. Clinical and radiographic outcomes are assessed using values including visual analogue scale (VAS) for back pain and Oswestry disability index (ODI). This data was collected preoperatively and at 6, 12, and 24 months postoperatively. Results: Surgical time and intraoperative blood loss of both groups were not significantly different (234 min vs. 267 min, 656 mL vs. 786 mL). Changes in VAS and ODI were similar in both groups. However, lateral cage mal-position ratio in group N was lower than that of group C (relative risk 1.64, Odds ratio 4.5) and postoperative cage sinking was significantly lower in group N (p = 0.033). Conclusions: Clinical outcomes are not significantly different, but radiographic outcomes of lateral cage mal-position and postoperative cage sinking were significantly lower in the navigation group.

Abstract
ABSTRACT Objective: To analyze the anatomic influence of the ribs related to the severity of thoracic spine burst fractures. Methods: A retrospective review of 28 patients with thoracic spine burst fractures hospitalized by the Spine Group of the Hospital Ortopédico de Passo Fundo between January 2002 and December 2016 was conducted. The kyphosis, vertebral collapse, and narrowing of the vertebral canal measurements were compared between patients who had fractures at the true and false rib levels (T1 to T10) and those with fractures at the floating rib levels (T11 to T12). Results: The kyphosis, vertebral collapse, and narrowing of the vertebral canal values, measured only for vertebrae pertaining to the rib cage, were low. In addition, there were no statistically significant differences between the measurements of the group of patients with fractures at the level of the true and false ribs (T1 to T10) and the group of patients whose fractures were at the level of the floating ribs (T11 and T12). Conclusion: The differences between the traumatic structural changes in the vertebrae with true and false ribs (T1 to T10) and the vertebrae with floating ribs (T11 and T12) were not significant in the present study.

Abstract
Lower lumbar spine burst fractures make up only 1% of all lumbar spine fractures. A burst fracture with neurological compromise, ligamentous injury, severe kyphotic deformity, or loss of anterior column support typically requires surgical stabilization. Treatment options at the L4 and L5 levels are challenging and often require an anterior/posterior approach. Very little has been reported on anterior approaches to the L4 and L5 levels when a corpectomy is required. Hence, we present a patient with a complex burst fracture of L4 and L5. She underwent a corpectomy of L4 and L5 and placement of an expandable cage through a window created between the aorta and the inferior vena cava via an anterior transperitoneal abdominal approach followed by posterior stabilization and fusion from L2 to the pelvis.

Abstract
BACKGROUND Short-segment transpedicular screw fixation is a common method for the treatment of thoracolumbar burst fractures (TBFs),but this technique has many problems. Therefore,the purpose of this article is to observe and evaluate the clinical efficacy of a novel transpedicular reducer that we designed for fractured vertebral body reduction and bone grafting in the treatment of TBFs. METHODS From July 2018 to November 2020, 70 cases of TBFs were included. Thirty-five patients were treated with the novel transpedicular reducer for reduction and bone grafting combined with pedicle screw fixation (observation group), and 35 patients were treated with short-segment transpedicular screw fixation (control group). Before the operation, after reduction, and 3 days, 3 months,and 12 months after the operation, the two groups were assessed, and compared with respect to the anterior and middle heights of the injured vertebrae, the ratios of the anterior and middle heights of the injured vertebral body to the respective heights of the adjacent uninjured vertebral bodies (AVBHr and MVBHr, respectively), and the Cobb angle of the patients. We compared the pain VAS score and quality of life GQOL-74 score at the last follow-up. Finally,we evaluated the distribution of bone grafts and bone healing 12 months after the operation. RESULTS The anterior height, middle height, AVBHr, MVBHr, and Cobb angle of the injured vertebral body in the observation after reduction, and 3 days, 3 months and 12 months post-operatively were compared with those of the injured vertebral body before operation. All of these parameters were improved, and the difference was statistically significant (p < 0.05). These parameters in the observation group at the above time points were significantly better than thoes in the control group at the corresponding time points (p < 0.05). The VAS scores at the last follow-up were significantly better than those of the control group (p < 0.05), but the GQOL-74 score differences were not statistically significant (p > 0.05). The observation group showed no obvious defects on CT at 12 months after the operation, and the bone healing was good. CONCLUSION The novel transpedicular reducer for reduction and bone grafting combined with pedicle screw fixation for TBFs has good clinical efficacy.

Traumatic compression fractures in thoracic-lumbar junction: vertebroplasty vs conservative management in a prospective controlled trial. J Neurointerv Surg 2021; 14:202-206. [PMID: 33758067 DOI: 10.1136/neurintsurg-2020-017141] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Revised: 02/13/2021] [Accepted: 03/10/2021] [Indexed: 01/05/2023]
Abstract
BACKGROUND Both surgery and conservative management are well established treatments for compression fractures of the thoraco-lumbar spine without neurological compromise. This article aims to compare the outcomes of conservative management to those of vertebroplasty, a relatively safe and simple procedure. METHODS 102 patients were admitted to our neurosurgical unit between January 2012 and February 2016, presenting with a single-level, post-traumatic A1 or A2 Mager l type fracture, affecting the thoracic-lumbar spine without any neurological deficits. After description of both treatment options, the patients were asked to choose between vertebroplasty or conservative treatment. Accordingly, the patients were allocated into two groups and a prospective non-randomized controlled trial was carried out. The first group (Group A) included 52 patients, treated with bed rest and an orthosis. The second group (Group B) of 50 patients underwent a percutaneous vertebroplasty. Pain intensity (assessed via visual analog scale (VAS)), disability degree (assessed via Oswestry Disability Index), ability to resume work (assessed via Denis work Scale), vertebral body height loss rate, regional kyphosis angle (Cobb's angle), duration of hospitalization and treatment-associated complications, were prospectively recorded in a database and analyzed. Follow ups were planned at 1, 6, and 12 months after the injury. RESULTS Group B, compared with group A, showed a faster improvement in VAS score as well as functional ability and return to work. Cobb's angle progression was significantly less in the surgical group. Morbidity, mortality, and complication rate were similar and comparable in both groups without a statistical difference (P<0.05) CONCLUSIONS: Vertebroplasty is a safe and effective treatment in post-traumatic thoracic-lumbar fractures compared with conservative management.

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
AbstractThe thoracolumbar junction (TLJ) is the most common site of traumatic spinal injury. Its management is a highly controversial area. There are no specific guidelines for management of these injuries. The primary goal of treatment of TLJ fractures involves protecting the spinal cord from further neural damage, obtaining the stability by reconstructing anatomical alignment of spinal column, and returning patients to workplace through early mobilization and rehabilitation. There is a great variation in evaluation of stability of these fractures, which is one of the crucial factors in deciding the treatment. Controversy also exists regarding conservative versus operative treatment, timing of intervention, anterior versus posterior approach, short versus long segment fixation, and bracing versus no bracing. This article had reviewed the conflicting results and recommendations for management of TLJ fractures of previously published reports in PubMed, PubMed Central, and Medline databases. We analyzed these related articles which addresses issues regarding evaluation of stability, indications for operative and conservative treatment, timing of surgery, surgical approach, and fusion length.

Abstract
BACKGROUND: Complete lesion after spinal cord injury (SCI) remains irreversible with little hope of neurological recovery. Newer interventions such as re-stimulation of damaged neurons using artificial agents and the use of stem cells for neuronal regeneration have shown promising results. AIM: This study was undertaken for evaluating the neurological status of acute SCI participants after stem cell augmentation and comparing them with other treatment methods. SETTING AND DESIGN: Randomized controlled trial in the northern Indian population. MATERIALS AND METHODS: A total 193 SCI participants of complete paraplegia with unstable T4–L2 injury having thoracolumbar injury severity score ≥4 were enrolled in this study. Participants were randomly allocated for three different treatment modalities, namely, conventional with stem cell augmentation (Group-1), conventional (Group-2), and conservative (Group-3). Neurological recovery after 1 year was evaluated through the ASIA Impairment Scale (AIS)-grading, sensory, and motor scores. STATISTICAL ANALYSIS: T-test for sensory-motor score analysis of each group and analysis of variance for comparison of same variables between the groups. RESULTS: After 1-year significant difference was observed in the AIS-grade, sensory and motor scores in-Group 1 (P < 0.001). In Group-1 versus 2, the mean difference at 1 year for AIS grade, sensory and motor scores were 0.40 (P = 0.010, 95% confidence interval [CI] 0.075–0.727), 8.52 (P = 0.030, 95% CI 0.619–16.419), and 4.55(P = 0.003, 95% CI 1.282–7.815), respectively. In Group-1 versus 3, 1.03, 19.02 and 7.22 (P < 0.001 for each of the parameters) and in Group-2 versus 3, 0.63 (P < 0.001), 10.49 (P = 0.009), and 2.68 (P = 0.019), respectively. CONCLUSIONS: Significant motor neurological recovery and AIS-grade promotion was observed in Group-1 as compared to Group-2 and 3.

Abstract
STUDY DESIGN This was a retrospective study of the clinical and radiologic outcomes of traumatic thoracolumbar (TL) burst fractures. OBJECTIVES We aimed to evaluate the clinical and radiologic outcomes after 6 years of follow-up of 144 patients with monosegmental TL burst fractures treated with percutaneous short-segment pedicle screw fixation, comparing two groups with versus without placement of an intermediate screw at the fractured vertebra. SUMMARY OF BACKGROUND DATA Traumatic TL fractures are the most common vertebral fractures, especially at the TL junction (T10-L2). Minimally invasive surgery (MIS) is a valuable treatment option for traumatic TL burst fractures. MATERIALS AND METHODS The clinical outcomes and radiologic parameters (Cobb angle, midsagittal index, and sagittal index) of 144 patients with traumatic monosegmental TL fractures treated with MIS were evaluated preoperatively, postoperatively, and after 3 and 6 years of follow-up. Patients were categorized into a nonintermediate screw group (nISG) and an intermediate screw group (ISG), and the groups were compared. RESULTS There were 71 patients (49.3%) in the nISG and 73 patients (50.7%) in the ISG. The radiologic parameters improved significantly more from the preoperative evaluation to the 6-year follow-up in the ISG than in the nISG (P<0.025). There were no significant differences in the mean Oswestry Disability Index (ODI) and Visual Analog Scale scores at the 6-year follow-up between the ISG and the nISG: 15.6% (ISG) versus 16.8% (nISG) for ODI (P<0.1) and 2.2 (ISG) versus 2.4 (nISG) for Visual Analog Scale score (P<0.85) (P<0.73). CONCLUSIONS MIS showed good clinical outcomes 6 years after surgery in both the ISG and the nISG. The additional intermediate screw significantly improved radiologic parameters but not clinical outcomes.

Abstract
OBJECTIVES To compare the efficacy and safety of novel percutaneous minimally invasive pedicle screw fixation and traditional open surgery for thoracolumbar fractures without neurological deficit. METHODS Sixty adult patients with single thoracolumbar fracture between June 2014 and June 2016 were recruited in this study, randomly divided into open fixation group (group A) or minimally invasive percutaneous fixation group (group B). Clinical and surgical evaluation including surgery time, blood losses, radiation times, hospital stay, and complication were performed. The two groups of patients with pre-operative and last follow-up anterior height ratio of fracture vertebral, Cobb angle of fracture vertebral, and VAS score of back pain were compared. RESULTS All patients completed valid follow-ups, with an average time period of 15.4 months (12-26 months). Group B achieved much better results in time of operation, intra-operative blood loss, and length of stay than group A (P < 0.05). Group A was significantly better than group B in the times of radiation (P < 0.05). The VAS score was significantly lower in group B than in group A at three days after the operation (P < 0.05). There were no significant differences between the two groups in the anterior height ratio of fracture vertebral, Cobb angle, and VAS score in the last follow-up (P > 0.05). No injured nerve or other severe complications occurred in both groups; one of the patients from group A had back and loin pain lasting for about one month, which resolved after analgesia and functional training. There was no significant difference between the two groups in incidence of complications. CONCLUSIONS Novel percutaneous pedicle screws with angle reset function can achieve the same effect as traditional open pedicle screw fixation in the treatment of thoracolumbar fractures without nerve injuries. Percutaneous minimally invasive pedicle screw fixation has the characteristics of shorter operative time, less bleeding, and less pain, but it needs more radiation times.

Abstract
Background and Aim: Instrumentation is commonly used in spinal surgery to stabilize the fracture. In the present study, we aimed to compare the early and late changes seen in bone production and degradation products in patients with traumatic spinal fracture who had been treated surgically or conservatively. Materials and Methods: Forty-three patients were admitted to the Neurosurgery Department with thoracolumbar or lumbar fracture in this prospective study. Patients were divided into two groups of surgically treated (n = 23) and nonsurgically/conservatively treated (n = 20) patients. The early and late changes seen in bone production and degradation products were compared in patients with traumatic spinal fracture who had been treated surgically or conservatively. Results: In conservatively treated patients, although osteocalcin level was slightly increased and deoxypiridinoline (DPD)/creatinine was slightly decreased after the treatment, the difference was not statistically significant (P = 0.08 and P = 0.539, respectively). There is no significant difference between admission time, posttreatment late period osteocalcin level, and DPD/creatinine ratio between the two group of patients (P = 0.215 and P = 0.236, respectively). Conclusion: We suggest that the healing and fusion processes in fractured vertebrae not only followed by the radiological examination but also by noninvasive biochemical changes seen in the serum levels of bone formation and resorption markers.

Abstract
Background The failure rate for the closed/non-surgical treatment of thoracic and lumbar vertebral body fractures (TLVBF) in trauma patients has not been adequately evaluated utilizing computed tomography (CT) studies. Methods From 2007 to 2008, consecutive trauma patients, who met inclusion criteria, with a CT diagnosis of acute TLVBF undergoing closed treatment were assessed. The failure rates for closed therapy, at 3 months post-trauma, were defined by progressive deformity, vertebral body collapse, or symptomatic/asymptomatic pseudarthrosis. The Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification was utilized to classify the fractures (groups A1 and non-A1 fractures) and were successively followed with CT studies. Results There were 54 patients with 91 fractures included in the study; 66 were A1 fractures, and 25 were non-A1 fractures. All had rigid bracing applied with flat and upright X-ray films performed to rule out instability. None had sustained spinal cord injuries. Thirteen patients (24%) failed closed therapy [e.g. 13 failed fractures (14%) out of 91 total fractures]. Five failed radiographically only (asymptomatic), and eight failed radiographically and clinically (symptomatic). A1 fractures had a 4.5% failure rate, while non-A1 fractures failed at a rate of 40%. Conclusion Failure of closed therapy for TLVBF in the trauma population is not insignificant. Non-A1 fractures had a much higher failure rate when compared to A1 fractures. We recommend close follow-up particularly of non-A1 fractures treated in closed fashion using successive CT studies.

Abstract
OBJECTIVE A multicenter, prospective, randomized equivalence trial comparing a thoracolumbosacral orthosis (TLSO) to no orthosis (NO) in the treatment of acute AO Type A3 thoracolumbar burst fractures was recently conducted and demonstrated that the two treatments following an otherwise similar management protocol are equivalent at 3 months postinjury. The purpose of the present study was to determine whether there was a difference in long-term clinical and radiographic outcomes between the patients treated with and those treated without a TLSO. Here, the authors present the 5- to 10-year outcomes (mean follow-up 7.9 ± 1.1 years) of the patients at a single site from the original multicenter trial. METHODS Between July 2002 and January 2009, a total of 96 subjects were enrolled in the primary trial and randomized to two groups: TLSO or NO. Subjects were enrolled if they had an AO Type A3 burst fracture between T-10 and L-3 within the previous 72 hours, kyphotic deformity < 35°, no neurological deficit, and an age of 16-60 years old. The present study represents a subset of those patients: 16 in the TLSO group and 20 in the NO group. The primary outcome measure was the Roland Morris Disability Questionnaire (RMDQ) score at the last 5- to 10-year follow-up. Secondary outcome measures included kyphosis, satisfaction, the Numeric Rating Scale for back pain, and the 12-Item Short-Form Health Survey (SF-12) Mental and Physical Component Summary (MCS and PCS) scores. In the original study, outcome measures were administered at admission and 2 and 6 weeks, 3 and 6 months, and 1 and 2 years after injury; in the present extended follow-up study, the outcome measures were administered 5-10 years postinjury. Treatment comparison between patients in the TLSO group and those in the NO group was performed at the latest available follow-up, and the time-weighted average treatment effect was determined using a mixed-effects model of longitudinal regression for repeated measures averaged over all time periods. Missing data were assumed to be missing at random and were replaced with a set of plausible values derived using a multiple imputation procedure. RESULTS The RMDQ score at 5-10 years postinjury was 3.6 ± 0.9 (mean ± SE) for the TLSO group and 4.8 ± 1.5 for the NO group (p = 0.486, 95% CI -2.3 to 4.8). Average kyphosis was 18.3° ± 2.2° for the TLSO group and 18.6° ± 3.8° for the NO group (p = 0.934, 95% CI -7.8 to 8.5). No differences were found between the NO and TLSO groups with time-weighted average treatment effects for RMDQ 1.9 (95% CI -1.5 to 5.2), for PCS -2.5 (95% CI -7.9 to 3.0), for MCS -1.2 (95% CI -6.7 to 4.2) and for average pain 0.9 (95% CI -0.5 to 2.2). CONCLUSIONS Compared with patients treated with a TLSO, patients treated using early mobilization without orthosis maintain similar pain relief and improvement in function for 5-10 years.

Abstract
Aim: To study the functional and radiological outcomes in cases managed conservatively for single-level traumatic thoracolumbar spine fractures without neurological deficit. Materials and Methods: In this prospective study design, thirty patients who presented to tertiary care hospital and diagnosed with posttraumatic thoracolumbar vertebral fracture without any neurodeficit were recruited. All the patients were managed conservatively as per the protocol which included bed rest, spinal braces, and physiotherapy. Adequate analgesia was given wherever necessary. The patients were followed at regular intervals up to a maximum of 2 years. Clinically visual analog scale (VAS) score and Roland Morris Disability Questionnaire (RMDQ)-24 were assessed and radiologically local vertebral kyphosis, scoliosis, and loss of body height were noted at each follow-up. Results: The data was statistically analyzed and the results were as follows. Thoracolumbar fractures were more in young adults (<26 years) and more so among the males (80% cases). The most common fracture type in our study was compression fracture. The most common site involved in our study was L1 vertebra (36.7%). There was a significant decrease of VAS score (pain score) in 79% cases with the maximum decrease in type A1 fracture. The mean RMDQ-4 score in our study was 5.53. The overall progression of kyphosis was 1.9°. There was no relation found between the kyphotic deformity and the clinical outcomes (VAS and RMDQ-24 scores). Canal size changes were found to be insignificant at the end of 2 years compared to baseline. Conclusion: Study showed favorable outcomes in terms of return to daily activities, making it a good option in managing Type A1 dorsolumbar fractures. Though there was a progression of kyphosis but no neurological deficit was seen.

Abstract
Background This study aimed to compare the surgical outcomes between open pedicle screw fixation (OPSF) and percutaneous pedicle screw fixation (PPSF) for the treatment of thoracolumbar fractures, which has received scant research attention to date. Material/Methods Eight-four patients with acute and subacute thoracolumbar fractures who were treated with SSPSF from January 2013 to June 2014 at the Changzhou Hospital of Traditional Chinese Medicine (Changzhou, China) were retrospectively reviewed. The patients were divided into 4 groups: the OPSF with 4 basic screws (OPSF-4) group, the OPSF with 4 basic and 2 additional screws (OPSF-6) group, the PPSF with 4 basic screws (PPSF-4) group, and the PPSF with 4 basic and 2 additional screws (PPSF-6) group. The intraoperative, immediate postoperative, and over 1-year follow-up outcomes were evaluated and compared among these groups. Results Blood loss in the PPSF-4 group and the PPSF-6 group was significantly less than in the OPSF-4 group and the OPSF-6 group (P<0.05). The OPSF-6 group exhibited significantly higher immediate postoperative correction percentage of anterior column height of fractured vertebra than the other 3 groups (P<0.05), and higher correction of sagittal regional Cobb angle and kyphotic angle of injured vertebra than in the PPSF-4 and -6 groups (P<0.05). In addition, there was no significant difference in the correction loss of percentage of anterior column height, and loss of sagittal Cobb angle and kyphotic angle of fractured vertebrae at final follow-up among the 4 groups (P>0.05). Conclusions OPSF with 6 screws had an advantage in the correction of injured vertebral height and kyphosis, and PPSF reduced the intraoperative blood loss of patients.

Abstract
Objectives: Classification methods that are currently being used for clinical decision making in thoracolumbar fractures, are limited by reproducibility and prognostic value. Additionally, they do not include kyphosis. As a posttraumatic kyphosis is related to persistent pain, it is of importance to determine a risk of posttraumatic kyphosis based on fracture type and patient characteristics. Purpose: To determine risk factors (AO classification, age, gender, localization) that may lead to progressive kyphosis after a thoracolumbar fracture. Materials and Methods: Retrospective radiographic analysis of a consecutive patientcohort that presented in our clinic with a traumatic fracture of the thoracolumbar spine between 2004 and 2011. Cobb angle, Gardner angle, vertebral compression angle and anterior vertebral body compression were measured on plain radiographs, direct post-trauma and at follow-up. Results: Age and localization are not significantly correlated, but there seems to be an increased risk of progression of kyphosis in age > 50 years and fractures localized at Th12 or L1. A3 type fractures are significantly more at risk for posttraumatic kyphosis compared to A1 and A2 type fractures. 30-50% of the A3 type fractures have an end Gardner angle and end vertebral compression angle of more than 20 degrees. Conclusion: AO-type A3 fractures appear to be at risk of progression of kyphosis. Localization at Th12-L1 and age above 50 years seem to be risk factors for significant posttraumatic kyphosis. These findings should be used in patient counseling and a meticulous evaluation by weekly radiographs is recommended to determine the treatment strategy of thoracolumbar fractures.

Abstract
BACKGROUND The purpose of this study was to prospectively assess the sensitivity of clinical examination to screen for thoracolumbar spine (TLS) injury in awake and alert blunt trauma patients with distracting injuries. METHODS From December 2012 to June 2014, all blunt trauma patients older than 13 years were prospectively evaluated as per standard TLS examination protocol at a Level 1 trauma center. Awake and alert patients with Glasgow Coma Scale (GCS) score of 14 or greater underwent clinical examination of the TLS. Clinical examination was performed regardless of distracting injuries. Patients with no complaints of pain or tenderness on examination of the TLS were considered clinically cleared of injury. Patients with distracting injuries, including those clinically cleared and those with complaints of TLS pain or tenderness, underwent computed tomographic scan of the entire TLS. Patients with minor distracting injuries were not considered to have a distracting injury. RESULTS A total of 950 blunt trauma patients were entered, 530 (56%) of whom had at least one distracting injury. Two hundred nine patients (40%) with distracting injuries had a positive TLS clinical examination result, of whom 50 (25%) were diagnosed with TLS injury. Three hundred twenty-one patients (60%) with distracting injuries were initially clinically cleared, in whom 17 (5%) TLS injuries were diagnosed. There were no missed injuries that required surgical intervention, with only four injuries receiving TLS orthotic bracing. This yielded an overall clinical clearance sensitivity for injury of 75% and sensitivity for clinically significant injury of 89%. CONCLUSION In awake and alert blunt trauma patients with distracting injuries, clinical examination is a sensitive screening method for significant TLS injury. Radiologic assessment may be unnecessary for safe clearance of the asymptomatic TLS in patients with distracting injuries. These findings suggest significant potential reduction of both health care cost and patient radiation exposure.

Abstract
OBJECT
The treatment of traumatic burst fractures unaccompanied by neurological impairment remains controversial and ranges from conservative management to 360° fusion. Because of the heterogeneity of fracture types, classification systems, and treatment options, comparative biomechanical studies might help to improve our knowledge. The aim of the current study was to create a standardized fracture model to investigate burst fractures in a multisegmental setting.
METHODS
A total of 28 thoracolumbar fresh-frozen human cadaveric spines were used. The spines were dissected into segments (T11–L3). The T-11 and L-3 vertebral bodies were embedded in Technovit 3040 (cold-curing resin for surface testing and impressions). To simulate high energy, a metallic drop tower was designed. Stress risers were used to ensure comparable fractures. CT scans were acquired before and after fracture. All fractures were classified using the AO/OTA classification.
RESULTS
The preparation and embedding of the spine segments worked well. No repositioning or second embedding of the specimen, even after fracture, was required. It was possible to create single burst fractures at the L-1 level in all 28 spine segments. Among the 28 fractures there were 16 incomplete burst fractures (Type A3.1), 8 burst-split fractures (Type A3.2), and 4 complete burst fractures (Type A3.3). The differences before and after fracture for stiffness and for anterior, posterior, and central heights were all significant (p < 0.05).
CONCLUSIONS
The ability to create reproducible burst fractures of a single vertebral body in a thoracolumbar spine segment may serve as a basis for future biomechanical studies that will provide better understanding of mechanical properties or fixation techniques.

Abstract
STUDY DESIGN In vitro biomechanics study. OBJECTIVE To determine whether kyphoplasty is an adequate stand-alone treatment for restoring biomechanical stability in the spine after experiencing high-energy vertebral burst fractures. SUMMARY OF BACKGROUND DATA Kyphoplasty in the treatment of high-energy vertebral burst fractures has been shown by previous studies to significantly improve stiffness when used in conjunction with pedicle screw instrumentation. However, it is not known whether kyphoplasty as a stand-alone treatment may be an acceptable method for restoring biomechanical stability of a spinal motion segment post-burst fracture while allowing flexibility of the motion segment through the intervertebral discs. METHODS Young cadaveric spines (15-50 yr old; 3 males and 1 female; bone mineral density 0.27-0.31 gHA/cm) were divided into motion segments consisting of 3 intact vertebrae separated by 2 intervertebral discs (T11-L1 and L2-L4). Mechanical testing in axial, flexion/extension, lateral bending, and torsion was performed on each specimen in an intact state, after an experimentally simulated burst fracture and postkyphoplasty. Computed tomography was used to confirm the burst fractures and quantify cement placement. RESULTS Between the intact and burst-fractured states significant decreases in stiffness were seen in all loading modes (63%-69%). Burst fracture increased the average angulation of the vertebral endplates 147% and decreased vertebral body height by an average of 40%. Postkyphoplasty, only small recoveries in stiffness were seen in axial, flexion/extension, and lateral bending (4%-12%), with no improvement in torsional stiffness. Large angular deformations (85%) and height loss (31%) remained postkyphoplasty as compared with the intact state. CONCLUSION Lack of overall improvement in biomechanical stiffness indicates failure of kyphoplasty to sufficiently restore stability as a stand-alone treatment after high-energy burst fracture. The lack of stability can be explained by an inability to biomechanically repair the compromised intervertebral discs. LEVEL OF EVIDENCE 3.

Abstract
The objective of this study was to assess which patient group had better outcomes for management of single level thoracolumbar spinal fractures. We prospectively collected data on the outcomes of patients having either conservatively managed, traditional open surgery, or minimally interventional surgery (MIS) for treatment of a single level thoracolumbar fracture. All patients had previously asymptomatic spines prior to their fractures and had a single level thoracolumbar burst fracture of more than 20° kyphosis. Fractures treated operatively, either via open surgery or MIS techniques, were corrected to less than 10° of residual kyphosis using a monoaxial pedicle screw construct 2 levels above & 2 levels below the fracture posteriorly only. The metalwork was removed between 6 months and 1 year post operatively to remobilise the spinal segments. All patients were then evaluated at least 6 months after metal work removal and at 18 months post fracture using radiographs and the Oswestry Disability Index (ODI). Those patients treated with MIS techniques demonstrated superior outcomes compared to traditional open techniques and conservative methods of treatment, with significantly reduced hospital stay, better return to work & leisure, and the best chance of restoring their spine to near its pre-injury status. We would recommend MIS techniques as the best way of treating single level thoracolumbar spinal fractures. There is a significant improvement in ODI when treated by MIS over open surgical methods.

Abstract
Traumatic fractures of the thoracolumbar spine are relatively common occurrences that can be a source of pain and disability. Similarly, osteoporotic vertebral fractures are also frequent events and represent a significant health issue specific to the elderly. Neurologically intact patients with traumatic thoracolumbar fractures can commonly be treated nonoperatively with bracing. Nonoperative treatment is not suitable for patients with neurological deficits or highly unstable fractures. The role of operative versus nonoperative treatment of burst fractures is controversial, with high-quality evidence supporting both options. Osteoporotic vertebral fractures can be managed with bracing or vertebral augmentation in most cases. There is, however, a lack of high-quality evidence comparing operative versus nonoperative fractures in this population. Bracing is a low-risk, cost-effective method to treat certain thoracolumbar fractures and offers efficacy equivalent to that of surgical management in many cases. The evidence for bracing of osteoporotic-type fractures is less clear, and further investigation will be necessary to delineate its optimal role.

Abstract
OBJECT The overall evidence for nonoperative management of patients with traumatic thoracolumbar burst fractures is unknown. There is no agreement on the optimal method of conservative treatment. Recent randomized controlled trials that have compared nonoperative to operative treatment of thoracolumbar burst fractures without neurological deficits yielded conflicting results. By assessing the level of evidence on conservative management through validated methodologies, clinicians can assess the availability of critically appraised literature. The purpose of this study was to examine the level of evidence for the use of conservative management in traumatic thoracolumbar burst fractures. METHODS A comprehensive search of the English literature over the past 20 years was conducted using PubMed (MEDLINE). The inclusion criteria consisted of burst fractures resulting from a traumatic mechanism, and fractures of the thoracic or lumbar spine. The exclusion criteria consisted of osteoporotic burst fractures, pathological burst fractures, and fractures located in the cervical spine. Of the studies meeting the inclusion/exclusion criteria, any study in which nonoperative treatment was used was included in this review. RESULTS One thousand ninety-eight abstracts were reviewed and 447 papers met inclusion/exclusion criteria, of which 45 were included in this review. In total, there were 2 Level-I, 7 Level-II, 9 Level-III, 25 Level-IV, and 2 Level-V studies. Of the 45 studies, 16 investigated conservative management techniques, 20 studies compared operative to nonoperative treatments, and 9 papers investigated the prognosis of conservative management. CONCLUSIONS There are 9 high-level studies (Levels I-II) that have investigated the conservative management of traumatic thoracolumbar burst fractures. In neurologically intact patients, there is no superior conservative management technique over another as supported by a high level of evidence. The conservative technique can be based on patient and surgeon preference, comfort, and access to resources. A high level of evidence demonstrated similar functional outcomes with conservative management when compared with open surgical operative management in patients who were neurologically intact. The presence of a neurological deficit is not an absolute contraindication for conservative treatment as supported by a high level of evidence. However, the majority of the literature excluded patients with neurological deficits. More evidence is needed to further classify the appropriate burst fractures for conservative management to decrease variables that may impact the prognosis.

Abstract
Study Design Systematic literature review. Objective The management of traumatic thoracolumbar burst fractures (TLBF) remains challenging, and analyzing the levels of evidence (LOEs) for treatment practices can reform the decision-making process. However, no review has yet evaluated the operative management of traumatic thoracolumbar burst fractures with particular attention placed on LOE from an established methodology. The objective of the present study was to characterize the literature evidence for TLBF, specifically for operative management. Methods A comprehensive search of the English literature over the past 20 years was conducted using PubMed (MEDLINE). The inclusion criteria consisted of (1) traumatic burst fractures (2) in the thoracic or lumbar spine. Exclusion criteria included (1) osteoporotic burst fractures, (2) pathologic burst fractures, (3) cervical fractures, (4) biomechanical studies or those involving cadavers, and (5) computer-based studies. Studies were assigned an LOE and those meeting level 1 or 2 were included. Results From 1,138 abstracts, 272 studies met the criteria. Twenty-three studies (8.5%) met level 1 (n = 4, 1.5%) or 2 (n = 19, 7.0%) criteria. All 23 studies were reported. Conclusions The literature contains a high LOE to support the operative management of traumatic thoracolumbar burst fractures. For patients who are neurologically intact, a high LOE demonstrated similar functional outcomes, lower complication rates, and less costs with conservative management when compared with surgical management. There is a high LOE for short- or long-segment pedicle instrumentation without fusion and less invasive (percutaneous and paraspinal) approaches. Furthermore, the posterior approaches are associated with lower complications as opposed to the anterior or combined approaches.

Abstract
BACKGROUND Studies comparing operative with nonoperative treatment of a stable burst fracture of the thoracolumbar junction in neurologically intact patients have not shown a meaningful difference at early follow-up. To our knowledge, longer-term outcome data have not before been presented. METHODS From 1992 to 1998, forty-seven consecutive patients with a stable thoracolumbar burst fracture and no neurological deficit were evaluated and randomized to one of two treatment groups: operative treatment (posterior or anterior arthrodesis) or nonoperative treatment (a body cast or orthosis). We previously reported the results of follow-up at an average of forty-four months. The current study presents the results of long-term follow-up, at an average of eighteen years (range, sixteen to twenty-two years). As in the earlier study, patients at long-term follow-up indicated the degree of pain on a visual analog scale and completed the Roland and Morris disability questionnaire, the Oswestry Disability Index (ODI) questionnaire, and the Short Form-36 (SF-36) health survey. Work and health status were obtained, and patients were evaluated radiographically. RESULTS Of the original operatively treated group of twenty-four patients, follow-up data were obtained for nineteen; one patient had died, and four could not be located. Of the original nonoperatively treated group of twenty-three patients, data were obtained for eighteen; two patients had died, and three could not be located. The average kyphosis was not significantly different between the two groups (13° for those who received operative treatment compared with 19° for those treated nonoperatively). Median scores for pain (4 cm for the operative group and 1.5 cm for the nonoperative group; p = 0.003), ODI scores (20 for the operative group and 2 for the nonoperative group; p <0.001) and Roland and Morris scores (7 for the operative group and 1 for the nonoperative group; p = 0.001) were all significantly better in the group treated nonoperatively. Seven of eight SF-36 scores also favored nonoperative treatment. CONCLUSIONS While early analysis (four years) revealed few significant differences between the two groups, at long-term follow-up (sixteen to twenty-two years), those with a stable burst fracture who were treated nonoperatively reported less pain and better function compared with those who were treated surgically.

Abstract
Thoracolumbar spine fractures are common injuries that can result in significant disability, deformity and neurological deficit. Controversies exist regarding the appropriate radiological investigations, the indications for surgical management and the timing, approach and type of surgery. This review provides an overview of the epidemiology, biomechanical principles, radiological and clinical evaluation, classification and management principles. Literature review of all relevant articles published in PubMed covering thoracolumbar spine fractures with or without neurologic deficit was performed. The search terms used were thoracolumbar, thoracic, lumbar, fracture, trauma and management. All relevant articles and abstracts covering thoracolumbar spine fractures with and without neurologic deficit were reviewed. Biomechanically the thoracolumbar spine is predisposed to a higher incidence of spinal injuries. Computed tomography provides adequate bony detail for assessing spinal stability while magnetic resonance imaging shows injuries to soft tissues (posterior ligamentous complex [PLC]) and neurological structures. Different classification systems exist and the most recent is the AO spine knowledge forum classification of thoracolumbar trauma. Treatment includes both nonoperative and operative methods and selected based on the degree of bony injury, neurological involvement, presence of associated injuries and the integrity of the PLC. Significant advances in imaging have helped in the better understanding of thoracolumbar fractures, including information on canal morphology and injury to soft tissue structures. The ideal classification that is simple, comprehensive and guides management is still elusive. Involvement of three columns, progressive neurological deficit, significant kyphosis and canal compromise with neurological deficit are accepted indications for surgical stabilization through anterior, posterior or combined approaches.

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.

Orthosis versus no orthosis for the treatment of thoracolumbar burst fractures without neurologic injury: a multicenter prospective randomized equivalence trial. Spine J 2014; 14:2557-64. [PMID: 24184649 DOI: 10.1016/j.spinee.2013.10.017] [Citation(s) in RCA: 78] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2013] [Revised: 09/20/2013] [Accepted: 10/17/2013] [Indexed: 02/08/2023]
Abstract
BACKGROUND CONTEXT Thoracolumbar burst fractures have good outcomes when treated with early ambulation and orthosis (TLSO). If equally good outcomes could be achieved with early ambulation and no brace, resource utilization would be decreased, especially in developing countries where prolonged bed rest is the default option because bracing is not available or affordable. PURPOSE To determine whether TLSO is equivalent to no orthosis (NO) in the treatment of acute AO Type A3 thoracolumbar burst fractures with respect to their functional outcome at 3 months. STUDY DESIGN A multicentre, randomized, nonblinded equivalence trial involving three Canadian tertiary spine centers. Enrollment began in 2002 and 2-year follow-up was completed in 2011. PATIENT SAMPLE Inclusion criteria included AO-A3 burst fractures between T11 and L3, skeletally mature and older than 60 years, 72 hours from their injury, kyphotic deformity lower than 35°, no neurologic deficit. One hundred ten patients were assessed for eligibility for the study; 14 patients were not recruited because they resided outside the country (3), refused participation (8), or were not consented before independent ambulation (3). OUTCOME MEASURES Roland Morris Disability Questionnaire score (RMDQ) assessed at 3 months postinjury. The equivalence margin was set at δ=5 points. METHODS The NO group was encouraged to ambulate immediately with bending restrictions for 8 weeks. The TLSO group ambulated when the brace was available and weaned from the brace after 8 to 10 weeks. The following competitive grants supported this work: VHHSC Interdisciplinary Research Grant, Zimmer/University of British Columbia Research Fund, and Hip Hip Hooray Research Grant. Aspen Medical provided the TLSOs used in this study. The authors have no financial or personal relationships that could inappropriately influence this work. RESULTS Forty-seven patients were enrolled into the TLSO group and 49 patients into the NO group. Forty-six participants per group were available for the primary outcome. The RMDQ score at 3 months postinjury was 6.8 ± 5.4 (standard deviation [SD]) for the TLSO group and 7.7 ± 6.0 (SD) in the NO group. The 95% confidence interval (-1.5 to 3.2) was within the predetermined margin of equivalence. Six patients required surgical stabilization, five of them before initial discharge. CONCLUSIONS Treating these fractures using early ambulation without a brace avoids the cost and patient deconditioning associated with a brace and complications and costs associated with long-term bed rest if a TLSO or body cast is not available.

Abstract
BACKGROUND The surgical results of treating thoracolumbar and lumbar burst fractures were reported to be comparable between patients with and without fusion in an intermediate-term follow-up. To our knowledge, no prior report has compared the results of fusion and non-fusion with long-term follow-up. METHODS This study was designed to provide long-term evaluation of patients with a burst fracture of the thoracolumbar and lumbar spine treated with short-segment fixation who were randomly assigned to a fusion or non-fusion group. Patients older than sixty years of age at the time of injury and those who were lost to follow-up were excluded. Functional outcomes were evaluated using the Greenough Low-Back Outcome Score and the visual analog scale for back pain. Radiographic outcomes were focused on the vertebral body height of the injured vertebra, the kyphotic angle, and the regional segmental motion. RESULTS Twenty-two patients were enrolled in the non-fusion group, and twenty-four patients were enrolled in the fusion group. The average follow-up period was 134 months (range, 121 to 161 months). The average preoperative kyphotic angle was 16.4° for the non-fusion group and 19.5° for the fusion group. The average postoperative kyphotic angle was 1.5° for the non-fusion group and 4.0° for the fusion group. At the time of the latest follow-up, the average kyphotic angle was 13.8° for the non-fusion group and 14.7° for the fusion group. The average kyphotic angle between the two groups was similar at all follow-up times. A progressive decrease of the kyphotic angle was significant (p < 0.05) with time, regardless of fusion. The radiographic outcomes were similar between these two groups at all follow-up times, as were functional outcomes. More patients in the non-fusion group underwent additional surgery to remove implants. Regional segmental motion was preserved in the non-fusion group, with a mean motion (and standard deviation) of 4.2° ± 1.9°. CONCLUSIONS The long-term results of short segmental fixation with and without fusion for burst fractures of the thoracolumbar and lumbar spine were comparable. Regional segmental motion could be preserved without fusion, and bone graft donor site complications could be eliminated. LEVEL OF EVIDENCE Therapeutic Level II.

Abstract
Mono-segment transpedicular fixation is a method for the treatment of certain types of thoracolumbar spinal fracture. Finite element models were constructed to evaluate the biomechanics of mono-segment transpedicular fixation of thoracolumbar fracture. Spinal motion (T10–L2) was scanned and used to establish the models. The superior half of the cortical bone of T12 was removed and the superior half of the cancellous bone of the T12 body was assigned the material properties of injured bone to mimic vertebral fracture. Transpedicular fixation of T11 and T12 was performed to produce a mono-segment fixation model; T11 and L1 were fixed to produce a short-segment fixation model. Motion differences between functional units and von Mises stress on the spine and implants were measured under axial compression, anterior bending, extensional bending, lateral bending and axial rotation. We found no significant difference between mono- and short-segment fixations in the motion of any functional unit. Stress on the T10/T11 nucleus pulposus and T10/T11 and L1/L2 annulus fibrosus increased significantly by about 75% on anterior bending, extensional bending and lateral bending. In the fracture model, stress was increased by 24% at the inferior endplate of T10 and by 43% at the superior endplate of L2. All increased stresses were reduced after fixation and lower stress was observed with mono-segment fixation. In summary, the biomechanics of mono-segment pedicle screw instrumentation was similar to that of conventional short-segment fixation. As a minimally invasive treatment, mono-segment fixation would be appropriate for the treatment of selected thoracolumbar spinal fractures.

Abstract
BACKGROUND Traditionally, conservative treatment of thoracolumbar (TL) burst fractures without neurologic deficit has encompassed the application of an extension brace. However, their effectiveness on maintaining the alignment, preventing posttraumatic deformities, and improving back pain, disability and quality of life is doubtful. OBJECTIVE The objective was to identify and summarize the evidence from randomized controlled trials (RCTs) to determine whether bracing patients who suffer TL fractures adds benefices to the conservative manage without bracing. MATERIALS AND METHODS Seven databases were searched for relevant RCTs that compared the clinical and radiological outcomes of orthosis versus no-orthosis for TL burst fractures managed conservatively. Primary outcomes were: (1) Loss of kyphotic angle; (2) failure of conservative management requiring subsequent surgery; and (3) disability and pain outcomes. Secondary outcomes were defined by health-related quality of life and in-hospital stay. RESULTS Based on predefined inclusion criteria, only two eligible high-quality RCTs with a total of 119 patients were included. No significant difference was identified between the two groups regarding loss of kyphotic angle, pain outcome, or in-hospital stay. The pooled data showed higher scores in physical and mental domains of the Short-Form Health Survey 36 in the group treated without orthosis. CONCLUSION AND RECOMMENDATION The current evidence suggests that orthosis could not be necessary when TL burst fractures without neurologic deficit are treated conservatively. However, due to limitations related with number and size of the included studies, more RCTs with high quality are desirable for making recommendations with more certainty.

Abstract
Object
Thoracolumbar spine injuries are commonly encountered in patients with trauma, accounting for almost 90% of all spinal fractures. Thoracolumbar burst fractures comprise a high percentage of these traumatic fractures (45%), and approximately half of the patients with this injury pattern are neurologically intact. However, a debate over complication rates associated with operative versus nonoperative management of various thoracolumbar fracture morphologies is ongoing, particularly concerning those patients presenting without a neurological deficit.
Methods
A MEDLINE search for pertinent literature published between 1966 and December 2013 was conducted by 2 authors (G.G. and R.D.), who used 2 broad search terms to maximize the initial pool of manuscripts for screening. These terms were “operative lumbar spine adverse events” and “nonoperative lumbar spine adverse events.”
Results
In an advanced MEDLINE search of the term “operative lumbar spine adverse events” on January 8, 2014, 1459 results were obtained. In a search of “nonoperative lumbar spine adverse events,” 150 results were obtained. After a review of all abstracts for relevance to traumatic thoracolumbar spinal injuries, 62 abstracts were reviewed for the “operative” group and 21 abstracts were reviewed for the “nonoperative” group. A total of 14 manuscripts that met inclusion criteria for the operative group and 5 manuscripts that met criteria for the nonoperative group were included.
There were a total of 919 and 436 patients in the operative and nonoperative treatment groups, respectively. There were no statistically significant differences between the groups with respect to age, sex, and length of stay. The mean ages were 43.17 years in the operative and 34.68 years in the nonoperative groups. The majority of patients in both groups were Frankel Grade E (342 and 319 in operative and nonoperative groups, respectively). Among the studies that reported the data, the mean length of stay was 14 days in the operative group and 20.75 in the nonoperative group.
The incidence of all complications in the operative and nonoperative groups was 300 (32.6%) and 21 (4.8%), respectively (p = 0.1065). There was no significant difference between the 2 groups with respect to the incidence of pulmonary, thromboembolic, cardiac, and gastrointestinal complications. However, the incidence of infections (pneumonia, urinary tract infection, wound infection, and sepsis) was significantly higher in the operative group (p = 0.000875). The incidence of instrumentation failure and need for revision surgery was 4.35% (40 of 919), a significant morbidity, and an event unique to the operative category (p = 0.00396).
Conclusions
Due to the limited number of high-quality studies, conclusions related to complication rates of operative and nonoperative management of thoracolumbar traumatic injuries cannot be definitively made. Further prospective, randomized studies of operative versus nonoperative management of thoracolumbar and lumbar spine trauma, with standardized definitions of complications and matched patient cohorts, will aid in properly defining the risk-benefit ratio of surgery for thoracolumbar spine fractures.

Abstract
Object
The optimal management of unstable thoracolumbar fractures remains unclear. The objective of the present study was to evaluate the results of using an expandable prosthetic vertebral body cage (EPVBC) in the management of unstable thoracolumbar fractures.
Methods
Eighty-five patients with unstable T7–L4 thoracolumbar fractures underwent implantation of an EPVBC via an anterior approach combined with posterior fixation. Long-term functional outcomes, including visual analog scale and Oswestry disability index scores, were evaluated.
Results
In a mean follow-up period of 16 months, anterior fixation led to a significant increase in vertebral body height, with an average gain of 19%. However, the vertebral regional kyphosis angle was not significantly increased by anterior fixation alone. No significant difference was found between early postoperative, 3-month, and 1-year postoperative regional kyphosis angle and vertebral body height. Postoperative impaction of the prosthetic cage in adjacent endplates was observed in 35% of the cases, without worsening at last follow-up. Complete fusion was observed at 1 year postoperatively and no cases of infections or revisions were observed in relation to the anterior approach.
Conclusions
The use of EPVBCs for unstable thoracolumbar fractures is safe and effective in providing long-term vertebral body height restoration and kyphosis correction, with a moderate surgical and sepsis risk. Anterior cage implantation is an alternative to iliac bone graft fusion and is a viable option in association with a posterior approach, in a single operation without additional risks.

Abstract
BACKGROUND Percutaneous vertebroplasty (PVP) for patients with chronic painful osteoporotic compression fractures has not been extensively studied. OBJECTIVE To prospectively evaluate the efficacy of PVP for patients with chronic painful osteoporotic vertebral compression fractures (VCFs). METHODS Sixty-two consecutive patients with chronic painful osteoporotic VCFs for ≥3 months underwent PVP. All procedures were performed under local anesthesia. The outcomes were pain relief at one week, one month, three months, six months and one year, as measured by visual analogue scale, Oswestry Disability Index, Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) and Roland Morris Disability Questionnaire scores. RESULTS The PVP procedures were technically successful and well tolerated in all patients. Sixty-two patients underwent PVP on 92 vertebrae in 73 procedures three to five days after referral, and no 30-day mortality was observed. Compared with baseline scores, improvement in visual analogue scale, Oswestry Disability Index, QUALEFFO and Roland Morris Disability Questionnaire scores was significantly greater after PVP at one week (P<0.001), one month (P<0.001), three months (P<0.001), six months (P<0.001) and one year (P<0.001), and the number of patients using drugs for pain treatment was significantly reduced. Five new fractures were reported in five of 62 patients treated with PVP during follow-up. CONCLUSION PVP is effective in patients with chronic painful osteoporotic VCFs. Pain relief after PVP was immediate, was sustained for one year and may be an important factor for reducing persistent pain.

Abstract
BACKGROUND CONTEXT Traumatic fractures of the spine are most common at the thoracolumbar junction and can be a source of great disability. PURPOSE To review the most current information regarding the pathophysiology, injury pattern, treatment options, and outcomes. STUDY DESIGN Literature review. METHODS Relevant articles, textbook chapters, and abstracts covering thoracolumbar spine fractures with and without neurologic deficit from 1960 to the present were reviewed. RESULTS The thoracolumbar spine represents a unique system from a skeletal as well as neurological standpoint. The rigid rib-bearing thoracic spine articulates with the more mobile lumbar spine at the thoracolumbar junction (T10 - L2), the site of most fractures. A complete examination includes a careful neurologic examination of both motor and sensory systems. CT scans best describe bony detail while MRI is most efficient at describing soft tissues and neurological structures. The most recent classification system is that of the new Thoracolumbar Injury Classification and Severity Score. The different fracture types include compression fractures, burst fractures - both stable and unstable -, flexion-distraction injuries and fracture dislocations. Their treatment, both operative and non-operative depends on the degree of bony compromise, neurological involvement, and the integrity of the posterior ligamentous complex. Minimally invasive approaches to the care of thoracolumbar injuries have become more popular, thus, the evidence regarding their efficacy is presented. Finally, the treatment of osteoporotic fractures of the thoracolumbar spine is reviewed, including vertebroplasty and kyphoplasty, their risks and controversies, and senile burst fractures, as well. CONCLUSIONS Thoracolumbar spine fractures remain a significant source of potential morbidity. Advances in treatment have minimized the invasiveness of our surgery and in certain stable situations, eliminated it all together.

Percutaneous short-segment pedicle screw placement without fusion in the treatment of thoracolumbar burst fractures: is it effective?: comparative study with open short-segment pedicle screw fixation with posterolateral fusion. Acta Neurochir (Wien) 2013; 155:2305-12; discussion 2312. [PMID: 24018981 DOI: 10.1007/s00701-013-1859-x] [Citation(s) in RCA: 79] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2013] [Accepted: 08/20/2013] [Indexed: 12/12/2022]
Abstract
BACKGROUND Since introduction of the pedicle screw-rod system, short-segment pedicle screw fixation has been widely adopted for thoracolumbar burst fractures (TLBF). Recently, the percutaneous pedicle screw fixation (PPSF) systems have been introduced in spinal surgery; and it has become a popularly used method for the treatment of degenerative spinal disease. However, there are few clinical reports concerning the efficacy of PPSF without fusion in treatment of TLBF. The purpose of this study was to determine the efficacy and safety of short-segment PPSF without fusion in comparison to open short-segment pedicle screw fixation with bony fusion in treatment of TLBF. METHODS This study included 59 patients, who underwent either percutaneous (n = 32) or open (n = 27) short-segment pedicle screw fixation for stabilization of TLBF between December 2003 and October 2009. Radiographs were obtained before surgery, immediately after surgery, and at the final follow-up for assessment of the restoration of the spinal column. For radiologic parameters, Cobb angle, vertebral wedge angle, and vertebral body compression ratio were assessed on a lateral thoracolumbar radiograph. For patient's pain and functional assessment, the visual analogue scale (VAS), the Frankel grading system, and Low Back Outcome Score (LBOS) were measured. Operation time, and the amount of intraoperative bleeding loss were also evaluated. FINDINGS In both groups, regional kyphosis (Cobb angle) showed significant improvement immediately after surgery, which was maintained until the last follow up, compared with preoperative regional kyphosis. Postoperative correction loss showed no significant difference between the two groups at the final follow-up. In the percutaneous surgery group, there were significant declines of intraoperative blood loss, and operation time compared with the open surgery group. Clinical results showed that the percutaneous surgery group had a lower VAS score and a better LBOS at three months and six months after surgery; however, the outcomes were similar in the last follow-up. CONCLUSIONS Both open and percutaneous short-segment pedicle fixation were safe and effective for treatment of TLBF. Although both groups showed favorable clinical and radiologic outcomes at the final follow-up, PPSF without bone graft provided earlier pain relief and functional improvement, compared with open TPSF with posterolateral bony fusion. Despite several shortcomings in this study, the result suggests that ongoing use of PPSF is recommended for the treatment of TLBF.

Abstract
PURPOSE We propose to evaluate the complication rate in minimally invasive stabilization (MIS) for spine fractures and tumors, as a common alternative to open fusion and conservative treatment. METHODS From 2000 to 2010, 187 patients were treated by minimally invasive percutaneous fixation in 133 traumatic fractures and 54 primitive and/or secondary spine tumors. Complications were classified, according to the period of onset as intraoperative and postoperative, and according to the severity, as major and minor. RESULTS A total of 15 complications (8 %) were recorded: 5 intraoperative (3 %), 6 early postoperative (3 %) and 4 late postoperative (2 %); 6 were minor complications (3 %) and 9 were major complications (5 %). CONCLUSIONS Minimally invasive stabilization of selected spine pathologies appears to be a safe technique with low complication rate and high patient satisfaction. MIS reduces hospitalization and allows a fast functional recovery improving the quality of life.

Abstract
The efficacy of percutaneous vertebroplasty (PVP) for patients with chronic painful osteoporotic compression fractures remains unknown. The purpose of this study was to compare the efficacy of PVP and conservative treatment (CT) for pain relief and functional outcome in patients with chronic compression fractures and persistent pain. Ninety-six patients with chronic compression fractures confirmed by MRI and persistent severe pain for 3 months or longer were prospectively randomly assigned to undergo PVP (n=46, Group A) or CT (n=50, Group B). The primary outcome was pain relief and functional outcome at 1 week, 1 month, 3 months, 6 months and 1 year. A total of 89 patients (46 in Group A and 43 in Group B) completed the 1 year follow-up assessment. Pain relief and functional outcomes were significantly better in Group A than in Group B, as determined by visual analogue scale scores, Oswestry Disability Index scores, and Roland Morris Disability scores at 1 week, 1 month, 3 months, 6 months and 1 year (all p<0.001). The final clinical follow-up assessment indicated complete pain relief in 39 Group A patients and 15 Group B patients (p<0.001). PVP for patients with chronic compression fractures and persistent severe pain was associated with better pain relief and improved functional outcomes at 1 year compared to CT.

Abstract
BACKGROUND There is significant controversy surrounding the ideal management of thoracolumbar burst fractures. While several treatment and management algorithms have been proposed, the ideal treatment strategy for these fractures remains unsettled. The authors review their experience with short-segment posterior fusion followed by anterior thoracoscopic corpectomy for the treatment of unstable thoracolumbar burst fractures. METHODS We identified all patients treated by a single surgeon at our institution from 2002 to 2009 with short-segment posterior fusion followed by anterior thoracoscopic corpectomy for unstable thoracolumbar junction burst fractures. Demographic data, mechanism of injury, classification of fracture, Cobb angle, American Spinal Injury Association score, associated injuries, tobacco use, follow-up duration, and radiographic studies were all collected. Outcomes were assessed for fracture alignment (preoperative, postoperative, and long-term follow-up kyphosis), rate of fusion, neurological outcome, and treatment complications. RESULTS Thirty-two patients with burst fracture of the thoracolumbar junction defined as T10 to L1 were included. At a mean follow-up of 20.4 months, 90 % of patients had demonstrated radiographic evidence of fusion and 91 % retained the correction of their kyphotic deformity. There were three complications in the series. CONCLUSIONS Short-segment posterior fusion with thoracoscopic anterior corpectomy represents an alternative to traditional open treatment of thoracolumbar burst fractures. A thoracoscopic approach allows for a short-segment posterior fusion, reducing the loss of adjacent motion segments, minimizes morbidity associated with traditional open anterior approaches, allows for anterior and posterior column stabilization, and is associated with a high rate of bony fusion.

Abstract
Minimally invasive stabilization of thoracic and lumbar fractures without neurologic involvement is becoming a more frequent alternative to open fusion and conservative treatment. The authors analyzed the complication rate and limits of this technique in a consecutive series of 99 patients (127 thoracolumbar vertebral fractures) who underwent this technique between May 2005 and November 2009. Eighty-three patients had only spine injuries, whereas 16 had polytrauma injuries (mean Injury Severity Score, 25.2). In these 16 patients, percutaneous fixation was performed as a damage control procedure. The most frequent construct was monosegmental: 1 level above and 1 level below the fractured vertebra. In the remaining 21 patients, multilevel construction was performed for multiple injuries. Complications were analyzed according to the period of onset (intra- and postoperative) and the severity (major and minor). Twelve (12%) complications were recorded: 4 (4%) were intraoperative, 6 (6%) were early postoperative, and 2 (2%) were late postoperative; 4 (4%) were minor and 8 (8%) were major. Mean follow-up was 52 months (range; 36-90 months). All patients except 1 were considered healed after 6-month follow-up. The failed patient had an initial kyphosis greater than 20°, and a posterior open reduction and fusion would have been more appropriate. Minimally invasive stabilization of selected spine injuries is a safe technique with a low complication rate. The main goal of this approach is a fast recovery time, so any complication leading to an extended length of stay should be considered severe. An adequate learning curve is important to minimize complications.
