Introduction. The management of thoracolumbar burst fractures is controversial. The goal of our study was to evaluate whether the psychological factors or the late spinal deformities influence outcome and in particular quality of life following surgical treatment of burst fractures of the thoracolumbar spine. Material and methods. In a retrospective analysis, we evaluated outcome in 45 patients in whom burst fractures of the thoracolumbar spine without neurological deficits were surgically treated between April 2001 and November 2004. For this purpose, patient charts, surgery reports and x-ray images were analyzed consecutively. 29 patients could be examined physically and the outcome could be evaluated with VAS spine core, quality of life according to short-form 36 (SF36) and Beck Depression Inventory (BDI) with a minimum follow up of 30 months. Results. Mean VAS spine score was 60±26. Neither VAS spine score, nor quality of life results correlated with the following radiological findings: vertebral body angle, sagittal index and height of cranial disc space of the vertebra. Beck Depression Inventory (BDI) correlated with SF-36 score and VAS spine score (p< 0.05). Patients who were depressed showed significantly worse results in relation to the VAS spine score and the SF36 score (p< 0.01). Conclusion. For the first time, we could show, that psychological factors have high influence on functional outcome and health related quality of life in operative treated thoracolumbar burst fracture independent of x-ray findings. Therefore, we recommend inclusion of psychological components in the treatment and outcome-evaluation of the thoracolumbar burst fracture in future

Many authors recommend surgery to remove retropulsed bone fragments from the canal in burst fractures to 'decompress' the spinal canal. We believe, however, that neurological damage occurs at the moment of injury when the anatomy is most distorted, and is not due to impingement in the resting positions observed afterwards. We studied 20 consecutive patients admitted to our spinal injuries unit over a two-year period with a T12 or L1 burst fracture. There was no correlation between bony or canal disruption and the degree of neurological compromise sustained but there was a significant correlation between the energy of the injury (as gauged by the Injury Severity Score) and the neurological status (p < 0.001). This suggests that neurological injury occurs at the time of trauma rather than being a result of pressure from fragments in the canal afterwards and questions the need to operate simply to remove these fragments.

In 139 patients with burst fractures of the thoracic, thoracolumbar or lumbar spine, the least sagittal diameter of the spinal canal at the level of injury was measured by computerised tomography. By multiple logistic regression we investigated the joint correlation of the level of the burst fracture and the percentage of spinal canal stenosis with the probability of an associated neurological deficit. There was a very significant correlation between neurological deficit and the percentage of spinal canal stenosis; the higher the level of injury the greater was the probability. The severity of neurological deficit could not be predicted.

The purpose of this study was to determine whether patients with a burst fracture of the thoracolumbar spine treated by short segment pedicle screw fixation fared better clinically and radiologically if the affected segment was fused at the same time. A total of 50 patients were enrolled in a prospective study and assigned to one of two groups. After the exclusion of three patients, there were 23 patients in the fusion group and 24 in the non-fusion group. Follow-up was at a mean of 23.9 months (18 to 30). Functional outcome was evaluated using the Greenough Low Back Outcome Score. Neurological function was graded using the American Spinal Injury Association Impairment Scale. Radiological outcome was assessed on the basis of the angle of kyphosis.

Peri-operative blood transfusion requirements and duration of surgery were significantly higher in the fusion group (p = 0.029 and p < 0.001, respectively). There were no clinical or radiological differences in outcome between the groups (all outcomes p > 0.05). The results of this study suggest that adjunctive fusion is unnecessary when managing patients with a burst fracture of the thoracolumbar spine with short segment pedicle screw fixation.

Decision-making regarding operative versus non-operative treatment of patients with thoracolumbar burst fractures in the absence of neurological deficits is controversial, and evidence from trials is sparse. We present a systematic review and meta-analysis of randomised trials comparing operative treatment to non-operative treatment in the management of thoracolumbar burst fractures. With the assistance of a medical librarian, an electronic search of Medline Embase and Cochrane Central Register of Controlled trials was performed. Trials were included if they: were randomided, had radiologically confirmed thoracolumbar (T10-L3) burst fractures, had no neurological deficit, compared operative and non-operative management (regardless of modality used), and had participants aged 18 and over. We examined the following outcomes: pain, using a visual analogue scale (VAS), where 0=no pain and 100=worst pain; function, using the validated Roland Morris Disability Questionnaire (RMDQ); and Kyphosis (measured in degrees). Two randomised trials including 79 patients (41 operative vs. 38 non-operative) were identified. Both trials had similar quality, patient characteristics, outcome measures, rates of follow up, and times of follow up (mean=47 months). Individual patient data meta-analysis (a powerful method of meta-analysis) was performed, since data was made available by the authors. There were no between-group differences in sex, level of fracture, mechanism of injury, follow up rates or baseline pain, kyphosis and RMDQ scores, but there was a borderline difference in age (mean 44 years in operative group vs. 39 in non-operative group, p=0.046). At final follow up, there were no between group differences in VAS pain (25 in operative group vs. 22 non-operative, p=0.63), RMDQ scores (6.1 in operative group vs. 5.8 non-operative, p=0.85), or change in RMDQ scores from baseline (4.8 in operative group vs. 5.3 non-operative, p=0.70). But both kyphosis at final follow up (11 degrees vs. 16 degrees, p=0.009) and reduction in kyphosis from baseline (1.8 degrees vs. -3.3 degrees, p=0.003) were better in the operative group. Operative management of thoracolumbar burst fractures appears to improve kyphosis, but does not improve pain or function

The progressive kyphosis and pain in patients with acute thoracolumbar burst fractures treated conservatively so as the recurrent kyphosis after posterior reduction and fixation were associated to disc collapse rather than vertebral body compression. It depends on redistribution of the disc tissue in the changed morphology of the space after fractures of the endplate. The aim of this study is to evaluate the safety and the efficacy of balloon kyphoplasty with calcium phosphate, alone or associated to short posterior instrumentation, in the treatment of acute thoracolumbar burst fractures. Eleven fractures in ten consecutive patients with an average age of 48 years who sustained acute thoracolumbar traumatic burst fractures without neurological deficits were included in this study. The fractures were A1.2 (3), A3.1 (4) and A3.2 (4), according to AO classification. In 7 fractures (A1.2 and A3.1) the kyphopasty was performed alone in order to make the most of efficacy in fracture reduction, anterior and medium column stabilization and, as much as possible, segmental kyphosis correction. In the A3.2 fractures (4), that are unstable, the kyphoplasty was associated to a short posterior instrumentation. To avoid the PMMA long run complications in younger patients, we used a calcium phosphate cement. VAS, SF-36, Roland-Morris questionnaire (RMQ) and Oswestry low back pain disability questionnaire (ODQ) were used to evaluate pain, state of health, functional outcomes and spine disability. To the average follow-up time of 15.5 months (range 8–31) we did not observe statistically significant differences in 7 of 8 SF-36 domains in comparison to general healthy population of same sex and age. At the same follow-up, the spine disability questionnaire showed a functional restriction of 18% (ODQ) and 29,6% (RMQ) being 100% the maximum of disability. No bone cement leakage, no implant failure and no height correction loss were observed in any case. Our data confirm the safety and the efficacy of ballon kyphoplasty with calcium phosphate in the treatment of acute thoracolumbar burst fractures. In this way we can reduce the possible complications resulted from discal space collapse and obtain an early functional restoration. When performed alone, this mini invasive surgical technique offer the advantage of almost immediate return to daily activities. When associated to posterior instrumentation, it decreases the long run complications and allows to reduce the number of stabilized levels, maintaining, in part, the thoracolumbar junction movement

Background: It has been reported that there is poor correlation between neurological injury and degree of bony retropulsion in thoracolumbar burst fractures. 1. Wilcox et al. 2. showed biomechanically that there was poor concordance between the extent of post impact spinal canal occlusion and the maximum amount of occlusion that occurred at the moment of impact. In the current study we examined the possibility that variation in the termination of the conus medullaris may offer protection from neurological injury in a proportion of these fractures. Methods: A retrospective study was made of 39 patients (26M:13M, mean age 35.9 years, range 15 – 75 years) presenting with a single level thoracolumbar burst fracture (T12–L2) between 1998 and 2001. A whole spine MRI scan was performed on all patients and the level of the conus noted. Age, sex, injury severity score (ISS), neurological status (ASIA motor score) and the transverse spinal canal area (TSCA) of the vertebral levels either side of the fractured vertebra was measured. A predicted TSCA for the injured level was then calculated from the mean of the TSCA’s of the adjacent levels. The actual TSCA of the injured level was calculated and this enabled a percentage decrease of the TSCA to be worked out from the predicted value. Analysis was made of the presence or absence of neurological injury in relation to canal compromise and involvement of the conus. Results: Eighteen patients with neurological compromise and 21 with intact neurology (the age and sex distribution in the two groups were similar). The mean ± SD ASIA motor score of the patients studied was 90.4 ± 23. Mean ISS was 20.2 in the neurologically injured and 10.5 in the intact (p=0.0005). Mean TSCA of the canal was 218mm. 2. in the intact and 150mm. 2. in the injured groups (p=0.006) and mean %TSCA was 70 and 49 respectively (p=0.007). The conus lay between T12 and L2 in all patients. When the conus lay cranial to the fracture (n=13), 38% were neurologically intact. When the conus lay at the level of the fracture (n=26), 62% were intact (NS). Neurological deficit did not occur in the absence of neurological compression on MRI. Conclusion: Our study showed that the risk of neurological injury from a thoracolumbar burst fracture was not decreased when the conus lay outside the fracture zone. However, there was a statistically significant difference in percentage of canal compromise when the patients with neurological impairment were compared with those that were neurologically intact

Introduction: The management of patients with thoracolumbar burst fractures has evolved over the last 60 years from the days of conservative management through to the current era of anterior decompression combined with either anterior or posterior stabilisation. There is no doubt that surgical outcomes have improved markedly with the more modern techniques. Nevertheless, there are still technical and other difficulties, which the surgeon may encounter. Based upon his experience with posterior vertebrectomy and reconstruction for thoracolumbar tumours, the author has used this technique for the management of acute burst fractures in this region. This paper presents a review of 10 patients with severe thoracolumbar burst fracture or fracture dislocation managed since 1997, using a single stage posterior decompression, realignment and stabilisation/interbody fusion. Methods: Data were acquired prospectively on consecutive patients between June 1997 and October 2000. All patients underwent single stage posterior decompression via laminectomy and then a subtotal eggshell vertebrectomy with removal of any herniated bone fragment(s) or partial vertebrectomy/ pedicle subtraction osteotomy. Pedicle screw stabilisation was performed to include one or two vertebrae above and below the involved vertebra(e). The intervertebral discs adjacent to the fractured vertebra were removed prior to realigning the vertebral column and performing inter-body fusion using carbon fibre spacers and autograft (4 patients) or vertebral body reconstruction with Titanium mesh cages and autograft (6 patients). Results: The mean age was 37 years (21–52 years). There were six males and four females. Three patients had no neurological deficit. Seven had incomplete paraplegia, three of which were severe with no or only a flicker of leg movement. The principal fracture involved L1 in 6 patients, L2 in 2, L4 in 1 and L5 in 1. Seven had herniated bone fragments occupying 90+% of the spinal canal. Of the seven patients with incomplete paraplegia, all recovered the ability to walk. Two with conus lesions still self catheterize. There were no serious early complications. A serious late complication was the development at three months of a severe deep wound infection, which required debridement and subsequent anterior/ posterior revision surgery. One patient with severe polytrauma and an L4 burst fracture/dislocation has developed a chronic pain syndrome. Discussion: The decompression, realignment, interbody reconstruction and stabilisation of thoracolumbar burst fractures/dislocations using a single stage posterior technique is technically demanding but the neurological outcome and restoration of spinal balance in these 10 patients was gratifying. The procedure appears to have two advantages over an anterior decompression and reconstruction combined with anterior or posterior stabilisation: first, it appears to provide easier access and improved visualisation for lumbar burst fractures where the psoas muscle may be swollen and contused, and second, it allows for easier realignment of any coronal or sagittal deformity

Purpose of study: There is a controversy in the surgical treatment of unstable thoracolumbar burst fractures scoring high on the Load Sharing Classification (LSC). We have been treating unstable thoracolumbar fractures with postero-lateral fusion using short segment instrumentation and in this study we investigated our complication rate. Methods and results: We retrospectively reviewed notes and radiographs of patients presenting with thoracolumbar burst fractures and stabilised with a short-segment instrumented postero-lateral fusion between 1998 and 2007. We identified 31 patients who had adequate documentation and radiographs. Twenty patients had a high (> =7) LSC score and none of these fixations failed. Overall early and late complication rate was low (one wound infection, one dehiscence and four unrelated infections), the one metalwork failure related to infection. Fifty-five percent of patients returned to full-time work. Approximately 50% of correction of kyphosis was lost but the average kyphosis at final follow-up was 11 degrees that we thought was acceptable. Conclusion: We concluded that treating unstable burst fractures with posterior instrumented fusion alone using a pedicle screw construct does not result in late instrumentation failure, high complication rate or unacceptable final deformity. Ethics approval: None. Interest Statement: None

The evaluation of early results of combined percutaneous pedicle screw fixation and kyphoplasty for the management of thoraco-lumbar burst fractures. Between October 2008 and April 2009, 9 patients with thoracolumbar burst fractures underwent percutaneous short-segment pedicle screw fixation and augmentation kyphoplasty with calcium phosphate cement. All patients were selected according to the type of fracture (unstable type A3 fractures based on the Magerl classification) the absence of neurological signs and an intact posterior longitudinal ligament on the pre-operative MRI scan. Patient demographics, co-morbidities and complications were recorded. The main endpoints included Cobb angle correction, vertebral body height restoration and the length of hospital stay. There were 3 male and 6 female patients with an average age of 43.6 years. The average follow-up was 2.4 months. The mean kyphotic angulation improved from 18.40 pre-operatively to 6, 80 post-operatively. The loss of vertebral body height improved from a mean of 38.7 % pre-operatively to 12.1 % post-operatively. The average duration of surgery was 40 minutes with insignificant blood loss. There were no post-operative complications. The average length of hospital stay was 3.2 days. The combination of percutaneous short-segment pedicle screw fixation supplemented by balloon kypho-plasty for the management of thoracolumbar burst fractures with no neurological deficit offers correction of the normal thoracolumbar anatomy as well as augmentation of the anterior load-bearing column, using a minimally invasive technique. The early results are promising

The October 2012 Spine Roundup. 360. looks at: a Japanese questionnaire at work in Iran; curve progression in degenerative lumbar scoliosis; the cause of foot drop; the issue of avoiding the spinal cord at scoliosis surgery; ballistic injuries to the cervical spine; minimally invasive oblique lumbar interbody fusion; readmission rates after spinal surgery; clinical complications and the severely injured cervical spine; and stabilising the thoracolumbar burst fracture

We hypothesised whether MIS techniques confer any benefit when treating thoracolumbar burst fractures. This was a prospective, non-randomised study over the past seven years comparing conservative (bracing:n=27), conventional surgery (open techniques:n=23) and MIS techniques (n=21) for stabilisation and correction of all thoracolumbar spinal fractures with kyphosis of >20. 0. , using Camlok S-RAD 90 system (Stryker Spine). All patients previously had normal spines, sustained only a single level burst fracture (T12, L1 or L2) as their only injury. Age range 18–65 years. All patients in both operatively treated groups were corrected to under 10. 0. of kyphosis, posteriorly only. All pedicle screws/rods were removed between 6 months and 1 year post surgery to remobilise the stabilised segments once the spinal fracture had healed, using the original incisions and muscle splitting/sparing techniques. Patients were assessed via Oswestry Disability Index (ODI) and work/leisure activity status 1 year post fracture. The conservatively treated group fared worst overall, with highest length of stay, poorest return to work/activity, and with a proportion (5/27) requiring later intervention to deal with post-traumatic deformity. 19/27 returned to original occupation, at average 9 months. ODI 32%. Conventional open techniques fared better, with length of stay 5 days, most (19/23) returning to original work/activity, and none requiring later intervention. Average return to work was at 4 months. ODI 14%. MIS group fared best, with shorter length of stay (48 hours), all returning to original work/activity at average 2 months, and none requiring later intervention. ODI negligible. There was no loss of correction in either operatively treated groups. The Camlok S-RAD 90 system is a powerful tool for correction of thoracolumbar burst fractures, and maintains an excellent correction. MIS techniques provide the best outcomes in treating this group of spinal fractures, and offer patients the best chance of restoration to pre-fracture levels of activity

Introduction: The optimal treatment for acute thoracolumbar burst fractures remains controversial, particularly in the patient with minimal or no neurologic deficit. While this group could be treated conservatively, at Burwood we prefer to utilise short segment instrumented stabilisation. We wished to review the indications for surgical intervention and the outcomes in this group with emphasis on safety, rate of rehabilitation, function, and pain levels. Methods: The clinical notes and X-rays were reviewed for 34 consecutive patients with thoracolumbar burst fractures with minimal or no neurologic deficit, and treated by Dick fixator between August 1995 and September 2001. A questionnaire was mailed to all patients. Results: At presentation this group had a mean age of 30.7 yrs (range 16–59), mean kyphotic deformity (Cobb method) of 16.1°, decrease in vertebral body anterior height of 40.9%, and decrease in canal area of 41.2%. Operative fixation was successful in greatly improving both height and kyphosis. No major complication such as metal-ware breakage, thromboembolism, deep infection, or neurologic deterioration was encountered. Average operating time was 71 min, time to discharge was 8.4 days, except where an associated injury limited mobility (17.1 days). Questionnaires were returned by 29 of 34 patients at a mean of 3 years post-injury. All of these had returned to work or usual level of activity at 14.3 weeks (4–36 wks). Pain was experienced never or occasionally by 18 (62%), in relation to activity by 9 (31%), and on most days by 2 (7%). The average visual analog pain score was 2.1/10. No patient required regular or opioid analgesia. Discussion: This form of operative fixation appeared to benefit this group of patients by allowing rapid rehabilitation with early mobilisation, discharge, and return to work. Pain frequency and severity were both low at medium term follow up and no major complication was encountered

Introduction: The poor correlation between neurological injury and degree of retropulsion in thoracolumbar burst fractures has been identified, but not adequately explained. We have examined the possibility that variation in the termination of the conus medullaris may offer protection from neurological injury in a proportion of these fractures. Methods: A retrospective study was made of 39 patients presenting with single level thoracolumbar burst fractures between June 1998 and April 2001. Admission MRI was performed on all patients. Age, sex, ISS, neurological status, mode of treatment and any neurological recovery were recorded. From the MRI scans the levels of the conus and the fracture were noted. Transverse Spine Area(TSA) was measured at the cranial, caudal and injured levels. A predicted TSA and % TSA for the injury level was calculated from the mean of the two other levels. Analysis was of severity of neurological injury in relation to canal compromise and involvement of the conus. Results: 26 male and 13 female patients of mean age 35.9 (SD 17) years and mean ASIA motor score 90.4 (SD 23) were studied. Neither sex nor age distribution differed between 18 neurologically injured and 21 intact patients. Mean ISS was 20.2 in the neurologically injured and 10.5 in the intact (p=0.0005). Mean TSA of the canal was 218mm2 in the intact and 150mm2 in the injured groups (p=0.006) and mean %TSA was 70 and 49 respectively (p=0.007). The conus lay between T12 and L2 in all. When the conus lay cranial to the fracture (n=13), 38% were neurologically intact. When the conus lay at the level of the fracture (n=26), 62% were intact (NS). Neurological deficit did not occur in the absence of neurological compression on MRI. Conclusions: Neurological injury is not less likely when the conus lie outside the fracture zone. Canal compromise is a highly significant factor in neurological injury

Introduction: The management of thoraco-lumbar burst fractures remains controversial. Different authors have advocated immobilisation, external bracing or internal fixation by either anterior or posterior approaches. Advocates of posterior fixation have in general performed stabilisation one level above and one level below the site of the fracture, resulting in fixation of two motion segments. It is known that multi-segmental spinal fusion produces undesirable biomechanics. To stabilise the site of the fracture and avoid unnecessary fixation of an uninjured segment the senior author (T.S.) for selected patients has been using a novel technique of monosegmental fixation with placement of pedicle screws directly into the fractured vertebral body. Methods: All patients with thoraco-lumbar burst fractures admitted to St Vincents and Concord Hospitals between January 2001 and October 2003 were considered for monosegmental fixation. Patients with severe osteoporosis or complete loss of vertebral body height (“vertebra plana”) were excluded. All patients underwent surgical decompression and fixation within 10 days of injury. Fixation was obtained with 4 titanium pedicle screws and a single transverse connector (Xia System Stryker Spine). Reduction of kyphotic deformity was carried out in selected patients. Average blood loss for the procedure was 250 ml with no patients requiring transfusion. All patients had a minimum of 6 months radiological and clinical follow-up. Results: Since January 2001, 18 patients with thoracolumbar burst fractures (T10-L2) were treated with single-level pedicle screw fixation. All patients were mobilised within 10 days of surgery. One patient experienced a minor superficial wound infection. There were no other postoperative complications. All patients had a stable fusion construct at 6 weeks following surgery. No patient experienced neurological deficit or have developed a delayed kyphotic deformity. There were no instances of instrument failure. 17 out of 18 patients report no significant back pain with any limitation of function by three months following surgery. One patient reports mild mechanical lower back pain 12 months following the injury. Discussion: Single level fixation for selected cases of thoracolumbar burst fracture is a safe and effective procedure to decompress the neural elements and obtain fixation and fusion of the fractured segment. It allows for rapid mobilisation and avoids a two-level fusion procedure with its subsequent detrimental effect on spinal biomechanics. It is considerably less invasive than anterior/lateral approaches which require extensive muscle dissection, rib removal and even diaphragmatic division

Objective. To evaluate the outcomes of the treatment of acute thoracolumbar burst fractures by transpedicular balloon kyphoplasty with Calcium phosphate cement and posterior instrumented fusion. Methods: Twenty-three consecutive patients (average age 48 years) who sustained thoracolumbar A3-type burst fracture with or without neurologic deficit were included in this prospective study. Twenty-one out 23 patients had single fractures and the left 2 had each one additional A1 compression contiguous fracture. On admission 5(26%) out 23 patients had neurologic lesion (5 incomplete, one complete). Bilateral transpedicular balloon kyphoplasty was performed with quick hardening calcium phosphate cement to reduce segmental kyphosis and restore vertebral body height and supplementary pedicle screw instrumentation (long including 4 vertebrae for T9-L1 fractures and short (3 vertebrae) for L2 to L4 fractures. Gardner kyphosis angle, anterior and posterior vertebral body height ratio and spinal canal encroachment were calculated pre–to postoperatively. Results: All 23 patients were operated within two days after admission and were followed for at least 24 months after index surgery. Operating time and blood loss averaged 70 minutes and 250 cc respectively. The 5 patients with incomplete neurologic lesions improved by at least one ASIA grade, while no neurological deterioration was observed in any case. Overall sagittal alignment was improved from an average preoperative 16o to one degree kyphosis at final follow up observation. The anterior vertebral body height ratio improved from 0.6 preoperatively to 0.9 (P< 0.001) postoperatively, while posterior vertebral body height was improved from 0.95 to 1 (P< 0.01). Spinal canal encroachment was reduced from an average 32% preoperatively to 20% postoperatively. No differences in preoperative values and postoperative changes in radiographic parameters between short and long group were shown. Cement leakage was observed in 4 cases: three anterior to vertebral body and one into the disc without sequalae. In the last CT evaluation, continuity was shown between calcium phosphate and cancellous vertebral body bone. Posterolateral radiological fusion was achieved within 6–8 months after index operation. There was no instrumentation failure or measurable loss of sagittal curve and vertebral height correction in any group of patients. Conclusions: Balloon kyphoplasty with calcium phosphate cement secured with posterior long and short fixation in the thoracolumbar and lumbar spine respectively provided excellent immediate reduction of posttraumatic segmental kyphosis and significant spinal canal clearance and restored vertebral body height in the fracture level in an equal amount both in short and long instrumentation
