Abstract
STUDY DESIGN Prospective Observational Study. OBJECTIVE To determine the alignment of the AO Spine Thoracolumbar Injury Classification system and treatment algorithm with contemporary surgical decision making. METHODS 183 cases of thoracolumbar burst fractures were reviewed by 22 AO Spine Knowledge Forum Trauma experts. These experienced clinicians classified the fracture morphology, integrity of the posterior ligamentous complex and degree of comminution. Management recommendations were collected. RESULTS There was a statistically significant stepwise increase in rates of operative management with escalating category of injury (P < .001). An excellent correlation existed between recommended expert management and the actual treatment of each injury category: A0/A1/A2 (OR 1.09, 95% CI 0.70-1.69, P = .71), A3/4 (OR 1.62, 95% CI 0.98-2.66, P = .58) and B1/B2/C (1.00, 95% CI 0.87-1.14, P = .99). Thoracolumbar A4 fractures were more likely to be surgically stabilized than A3 fractures (68.2% vs 30.9%, P < .001). A modifier indicating indeterminate ligamentous injury increased the rate of operative management when comparing type B and C injuries to type A3/A4 injuries (OR 39.19, 95% CI 20.84-73.69, P < .01 vs OR 27.72, 95% CI 14.68-52.33, P < .01). CONCLUSIONS The AO Spine Thoracolumbar Injury Classification system introduces fracture morphology in a rational and hierarchical manner of escalating severity. Thoracolumbar A4 complete burst fractures were more likely to be operatively managed than A3 fractures. Flexion-distraction type B injuries and translational type C injuries were much more likely to have surgery recommended than type A fractures regardless of the M1 modifier. A suspected posterior ligamentous injury increased the likelihood of surgeons favoring surgical stabilization.

[PMID: 38510618 PMCID: PMC10951763 DOI: 10.1016/j.bas.2024.102745] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 12/27/2023] [Accepted: 01/03/2024] [Indexed: 03/22/2024]
Abstract
Introduction The treatment of traumatic thoracic and lumbar spine fractures remains controversial. To date no consensus exists on the correct choice of surgical approach and technique. Research question to provide a comprehensive up-to-date overview of the available different surgical methods and their quantified outcomes. Methods PubMed and EMBASE were searched between 2001 and 2020 using the term 'spinal fractures'. Inclusion criteria were: adults, ≥10 cases, ≥12 months follow-up, thoracic or lumbar fractures, and surgery <3 weeks of trauma. Studies were categorized per surgical technique: Posterior open (PO), posterior percutaneous (PP), stand-alone vertebral body augmentation (SA), anterior scopic (AS), anterior open (AO), posterior percutaneous and anterior open (PPAO), posterior percutaneous and anterior scopic (PPAS), posterior open and anterior open (POAO) and posterior open and anterior scopic (POAS). The PO group was used as a reference group. Results After duplicate removal 6042 articles were identified. A total of 102 articles were Included, in which 137 separate surgical technique cohorts were described: PO (n = 75), PP, (n = 39), SA (n = 12), AO (n = 5), PPAO (n = 1), PPAS (n = 1), POAO (n = 2) and POAS (n = 2). Discussion and conclusion For type A3/A4 burst fractures, without severe neurological deficit, posterior percutaneous (PP) technique seems the safest and most feasible option in the past two decades. If needed, PP can be combined with anterior augmentation to prevent secondary kyphosis. Furthermore, posterior open (PO) technique is feasible in almost all types of fractures. Also, this technique can provide for an additional posterior decompression or fusion. Overall, no neurologic deterioration was reported following surgical intervention.

Abstract
STUDY DESIGN Subgroup analysis of a multicenter prospective cohort study. OBJECTIVE To analyse surgical strategies applied to osteoporotic thoracolumbar osteoporotic fracture (OF) 5 injuries with anterior or posterior tension band failure and to assess related complications and clinical outcome. METHODS A multicenter prospective cohort study (EOFTT) was conducted at 17 spine centers including 518 consecutive patients who were treated for an osteoporotic vertebral fracture (OVF). For the present study, only patients with OF 5 fractures were analysed. Outcome parameters were complications, Visual Analogue Scale (VAS), Oswestry Disability Questionnaire (ODI), Timed Up & Go test (TUG), EQ-5D 5L, and Barthel Index. RESULTS In total, 19 patients (78 ± 7 years, 13 female) were analysed. Operative treatment consisted of long-segment posterior instrumentation in 9 cases and short-segment posterior instrumentation in 10 cases. Pedicle screws were augmented in 68 %, augmentation of the fractured vertebra was performed in 42%, and additional anterior reconstruction was done in 21 %. Two patients (11 %) received short-segment posterior instrumentation without either anterior reconstruction or cement-augmentation of the fractured vertebra. No surgical or major complications occurred, but general postoperative complications were observed in 45%. At a follow-up of mean 20 ± 10 weeks (range, 12 to 48 weeks), patients showed significant improvements in all functional outcome parameters. CONCLUSIONS In this analysis of patients with type OF 5 fractures, surgical stabilization was the treatment of choice and lead to significant short-term improvement in terms of functional outcome and quality of life despite a high general complication rate.

Spine J 2023; 23:315-324. [PMID: 36058516 DOI: 10.1016/j.spinee.2022.08.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 07/09/2022] [Accepted: 08/26/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Pedicle screw-rod assembly procedures following pedicle screw insertion include contouring and placing rods into screw tulips, introducing set screws into the tulip along the screw thread, applying a counter-torque holder and tightening all the set screws clockwise. Even if an appropriate pedicle screw is implanted, screw dislodgement after tightening of the tulip and set screw is not uncommon. Pedicle wall violation resulting from excessive rotational force due to inadequate use of a counter-torque holder might be the reason. However, the strain change in the pedicle during tulip-set screw tightening and the role of counter-torque have never been investigated. PURPOSE This study determined differences in the strain change in the outer and inner pedicle walls during tulip-set screw tightening; additionally, the influence of counter-torque on pedicle wall violation was elucidated. STUDY DESIGN A controlled biomechanical study; the strain values of outer and inner pedicle walls in cadaveric porcine L4-L5 vertebrae during tulip-set screw tightening with or without a counter-torque holder were measured. METHODS Twelve L4-L5 fresh-frozen porcine lumbar vertebrae were implanted with screw-rod constructs; the set screw was randomly locked into the tulip in the right L5, right L4, left L5 and left L4 testing groups. The maximal values from eight strain gauges (P-R-O: outer cortex of right pedicle in proximal vertebra; P-R-I: inner cortex of right pedicle in proximal vertebra; D-R-O: outer cortex of right pedicle in distal vertebra; D-R-I: inner cortex of right pedicle in distal vertebra; P-L-O: outer cortex of left pedicle in proximal vertebra; P-L-I: inner cortex of left pedicle in proximal vertebra; D-L-O: outer cortex of left pedicle in distal vertebra; D-L-I: outer cortex of left pedicle in proximal vertebra) for each specimen during tightening to 12 Nm were measured. RESULTS The maximal strain values of the ipsilateral strain gauges in all testing groups were almost significantly higher when a counter-torque holder was not used than when one was used. The strain values in the adjacent pedicle of specimens without a counter-torque holder were significantly increased: P-R-O and P-R-I in the right L5 group; D-R-I in the right L4 group; P-L-I and P-L-O in the left L5 group; D-L-O and D-L-I in the left L4 group. CONCLUSIONS The constraint effect of counter-torque during tulip-set screw tightening is necessary. Clockwise rotational force with a fragile lateral pedicle wall suggests that caution is required when using a counter-torque holder to tighten the right L5 and left L4 constructs. CLINICAL SIGNIFICANCE A counter-torque holder is important during tulip-set screw tightening; improper use may lead to adjacent pedicle wall violation, sequentially resulting in pedicle screw loosening.

Abstract
Background Osteoporotic thoracolumbar compression fractures have become a great social burden due to the aging tendency of population. This study is aimed at comparing the clinical and radiological outcomes of percutaneous kyphoplasty with or without pedicle screw fixation in patients with osteoporotic thoracolumbar fractures. Hypothesis. There is a difference in clinical outcomes between percutaneous kyphoplasty with pedicle screw fixation and percutaneous kyphoplasty. Methods This retrospective study included 87 patients who received percutaneous kyphoplasty with or without pedicle screw fixation between October 2015 and October 2017 at Ningbo No.6 Hospital and were followed for 2 years. A total of 40 patients received percutaneous kyphoplasty with pedicle screw fixation (PKPF group), and the other 47 patients had percutaneous kyphoplasty only (PKP group). The outcomes were measured using the visual analogue scale (VAS), Oswestry Disability Index (ODI), Cobb angle (CA), and anterior vertebra height rate (AVHr), which were calculated at preoperative admission and each follow-up visit. Complications including postoperative back pain, refracture, and fixation failure were collected from medical records. Results There was no significant difference in baseline characteristics or preoperative data between the two groups (p < 0.05) but significantly better improvements in VAS, ODI, CA, and AVHr at 12- and 24-month follow-up visits in the PKPF group compared with those of the PKP group. 23 (48.9%) patients in the PKP group had complications, whereas only 5 (12.5%) patients in the PKPF group presented complications including 2 postoperative back pain and 1 fixation failure (p = 0.04). Conclusions PKPF obtained longer correction and better improvement in VAS, ODI, and CA in patients with osteoporotic thoracolumbar vertebral fractures than PKP.

Reduce the fractured central endplate in thoracolumbar fractures using percutaneous pedicle screws and instrumentational maneuvers: Technical strategy and radiological outcomes.

Abstract
INTRODUCTION Traumatic thoracolumbar burst fracture is a common condition without a clear consensus on the best treatment approach. Percutaneous pedicle screw fixation (PPSF) techniques are widely used in practice, while its ability to correct fracture deformity is relatively weak, especially for the central area of the endplate. In this study, we reported a novel technique to reduce the fractured central endplate in thoracolumbar burst fractures. METHODS The new reduction technique uses six percutaneous pedicle screws for the fractured vertebra and its adjacent vertebrae. Pedicle screws implanted in the two adjacent vertebrae were parallel to the superior vertebral endplate, as routinely required. Two monoaxial pedicle screws implanted in the fractured vertebra were placed toward the anteroinferior portion of the fractured vertebral body. After routine instrumentation and ligamentotaxis reduction, the bolt heads of the four screws implanted in the adjacent vertebrae were first tightened, and then the bolt heads of the screws implanted in the fractured vertebra were gradually tighten to elevate the collapsed endplate. A fundamental principle of this technique is to implant the pedicle screw in the fractured vertebra towards the anteroinferior portion of the vertebra in such a way that the angle between the pedicle screw and the rod is oblique on lateral fluoroscopy. As such, when the bolt heads were tightened, the pedicle screws can be swung up to reduce the endplate fragments. RESULTS The novel technique was performed in 24 patients with neurologically intact thoracolumbar AO type A3 fractures. The middle vertebral height ratio was significantly improved from 69.7%±7.6% after routine reduction to 85.1%±4.5% postoperatively (p<0.01). No complication was noticed for this new reduction technique. At 6-month follow-up, no significant correction loss of the middle and posterior vertebral height ratios, Cobb angle, and vertebral wedge angle was observed, while 5.8% of correction loss was observed for the anterior vertebral height ratio. CONCLUSION The described reduction technique is simple, safe, and effective in reducing the collapsed central endplate in thoracolumbar burst fractures. Such a practical reduction strategy does not need additional medical costs.

Abstract
BACKGROUND There is no consensus on the treatment for spinal injuries resulting in thoracolumbar fractures without neurological impairment. Many trauma centers are opting for open surgery rather than a neurointerventional approach combining posterior percutaneous short fixation (PPSF) plus balloon kyphoplasty (BK). OBJECTIVE To assess the safety and efficacy of PPSF+BK and to estimate the expected improvement by clarifying the factors that influence improvement. METHODS We retrospectively reviewed patients who underwent PPSF+BK for the treatment of single traumatic thoracolumbar fractures from 2007 to 2019. Kyphosis, loss of vertebral body height (VBH), clinical and functional outcomes including visual analog scale and Oswestry disability index were assessed. We examined the overall effects in all patients by constructing a linear statistical model, and then examined whether efficacy was dependent on the characteristics of the patients or the fractures. RESULTS A total of 102 patients were included. No patient experienced neurological worsening or wound infections. The average rates of change were 74.4% (95% CI 72.6% to 76.1%) for kyphosis and 85.5% (95% CI 84.4% to 86.6%) for VBH (both p<0.0001). The kyphosis treatment was more effective on Magerl A3 and B2 fractures than on those classified as A2.3, as well as for fractures with slight posterior wall protrusion on the spinal canal. A higher postoperative visual analog scale score was predictive of poorer outcome at 1 year. CONCLUSIONS This is the largest series reported to date and confirms and validates this surgical treatment. All patients exhibited improved kyphosis and restoration of VBH. We advise opting for this technique rather than open surgery.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVES Doubts still remain whether a sufficient reduction of vertebral body fractures can be achieved if a percutaneous surgical approach is adopted. The aim of this retrospective cohort study was to analyze the reduction and perioperative complications using a percutaneous versus open surgical approach for dorsal stabilization. METHODS Patients suffering from a traumatic injury of the thoracic or lumbar spine who were treated with dorsal stabilization at our level 1 trauma center were included. From January 2007 through June 2009, only the open approach was used; from June 2009 through March 2014, only the percutaneous approach with a special reduction technique was used. Retrospectively, total reduction, perioperative and intraoperative data, and postoperative complications were analyzed. RESULTS Using the percutaneous (n=185) versus open surgical approach (n=91), the mean reduction over all spinal injuries was 7.7±6.6 versus 8.3±5.5 degrees, respectively. The mean operation time was 75.5±50.2 versus 71.5±41.9 minutes, respectively. There was no significant difference between the 2 treatment groups in terms of the total reduction (P=0.753) or operation time (P=0.814).After the percutaneous and open surgical approach, 7 (3.8%) and 22 (24.2%) complications were documented. Complications requiring interventions were more frequent in the open treatment group. CONCLUSIONS Percutaneous dorsal stabilization seems to be a good alternative to the traditional open surgical approach. The fracture's reduction is similar, whereas severe complications are reduced and the operation time is not prolonged. LEVEL OF EVIDENCE Level III-retrospective cohort study.

Abstract
Approximately 200,000 spinal fractures occur each year in Germany. The decimated stability of the vertebra often leads to type A fractures with a substantial influence by osteoporosis. A mobility preserving and gentle treatment has clear advantages compared to conservative treatment. The hybrid stabilization as a combination of minimally invasive dorsal stabilization and vertebral augmentation has become an established method. In the period from July 2014 to June 2015 a total of 205 spinal operations were documented. In the group of very old patients more than 80% were treated for a geriatric type A vertebral fracture, 24 with hybrid stabilization, 5 by percutaneous bisegmental, 22 by kyphoplasty stabilization and 13 by percutaneous polysegmental procedures. Furthermore, these 4 groups were also considered with respect to the treatment in geriatric trauma centers (GTC). The 4 forms of treatment achieved a mean remuneration of 11,238.77 €. For the individual treatment form of kyphoplasty there was an increase in the remuneration of 4276.54 €, when patients undergo geriatric complex treatment and the remuneration is according to the diagnosis-related groups (DRG) classification I34Z. In the field of operative treatment of geriatric vertebral fractures, the augmentative procedures of kyphoplasty and vertebroplasty are well-established but an injury-related involvement of adjacent spinal segments and continuity fractures are frequent occurrences so that a bisegmental hybrid stabilization is advantageous. In addition, the perioperative stress in hybrid stabilization is only negligibly longer so that hybrid stabilization and geriatric complex treatment can be recommended as the new standard in spinal surgery for the treatment of type A fractures in aged patients.

Which anatomic structures are responsible for the reduction loss after hybrid stabilization of osteoporotic fractures of the thoracolumbar spine? BMC Musculoskelet Disord 2020; 21:54.

Abstract
Introduction Hybrid stabilization is an accepted therapy strategy for unstable osteoporotic thoracolumbar fractures. However, a moderate reduction loss has been reported and it remains unclear which anatomic structure is responsible for the reduction loss. Methods This retrospective study was performed at a level I trauma center. Patients aged 61 and older were stabilized using hybrid stabilization after suffering acute and unstable osteoporotic vertebral body fractures at the thoracolumbar spine. Posterior stabilization was done short-segmental and minimal invasive with cement-augmentation of all pedicle screws. The minimum follow-up has been 2 years. The outcome parameters were the reduction loss and the relative loss of height of both intervertebral discs adjacent to the fractured vertebral body, the fractured vertebral body and a reference disc (intervertebral disc superior of the stabilization) between the postoperative and latest lateral radiographs. Additionally, implant positioning and loosening was analyzed. Results 29 mainly female (72%) patients (73.3 ± 6.0 years) were included. Fractures consisted of 26 incomplete burst fractures and 3 complete burst fractures of the thoracolumbar junction (Th11 – L2: 86%) and the midlumbar spine. The mean follow-up time was 36 months (range: 24–58 months). The mean reduction loss was 7.7° (range: 1–25). The relative loss of heights of both intervertebral discs adjacent to the fractured vertebral body, the reference disc, and the central vertebral body were significant. Thereby, the relative loss of the superior disc height was significant higher compared to the reference disc. Additionally, only the relative loss of central vertebral body height and reduction loss correlated significantly. There were no signs of implant loosening in any patient. Conclusions The mean reduction loss was moderate 3 years after hybrid stabilization of unstable osteoporotic vertebral fractures of the thoracolumbar spine. A significant loss of both adjacent disc heights and the central vertebral body was seen, with the highest loss in the superior adjacent disc significantly outranging the reference disc. The superior adjacent intervertebral disc and the central part of the fractured vertebral body seem to be responsible for the majority of reduction loss.

Abstract
Background Less invasive stabilization systems (LISSs) have gained popularity. However, limited quality of life (QOL) and clinical outcome data exist for trauma patients treated with LISSs. The objective of this study is to describe QOL and outcome for posterior percutaneous pedicle screw fixation in the management of traumatic thoracolumbar fractures. Methods Between January 2006 and December 2011, data from all patients treated with a posterior percutaneous pedicle screw fixation technique for thoracolumbar fractures were collected and analyzed. Sixty-nine patients met the inclusion criteria. Additional vertebral reduction and cement augmentation was used in 25 patients, when there was more than 50% of vertebral body comminution. Results Mean follow up of 19 months (range = 6-49 months). Fifty-one percent of the study population consisted of polytrauma patients, with 22% having injury severity score ≥ 15. In 6 cases (8.7%) there were perioperative complications. Response rate for the follow-up health survey was 78%, with a satisfactory overall median EuroQuol score of 0.811 (Q1-Q3 95% confidence interval = 0.709-0.897). Conclusions Posterior percutaneous pedicle screw fixation proves to be effective in the management of traumatic thoracolumbar fractures, with a good overall functional outcome. Percutaneous techniques that reduce perioperative morbidity are an alternative approach well suited for damage control orthopaedics, as long as there are no neurological deficits. Especially in polytrauma patients with spine fractures, the spinal column can be stabilized in an emergency setting, while limiting the risks of "a second hit" at the patients' already frail condition.

Abstract
INTRODUCTION Flexion-distraction fractures represent around 15% of all thoracolumbar fractures, with neurological deficit in 25% of cases. Optimal surgical strategy remains controversial. In neurologically intact patients, percutaneous fixation can offer quick stabilization with good deformity correction. If necessary, an additional minimally invasive anterior approach can complete the surgical strategy. We report results in a series of 28 thoracolumbar flexion-distraction fractures without neurologic deficit, treated using a minimally invasive approach. METHOD A single-center retrospective study was conducted for the period 2008-2015. Patients over 16 years of age with a flexion-distraction fracture without neurologic deficit were included. Analysis was based on preoperative CT-scan and measurement of post-traumatic kyphotic deformity. Surgery comprised posterior percutaneous fixation, alone or associated to an anterior step in case of discal lesion on preoperative MRI or of severe vertebral comminution. Operative time, blood loss and postoperative complications were recorded. Residual segmental kyphosis and bone healing were evaluated on CT at 1 year. RESULTS Seventeen males and 11 females were included (mean age, 29.2 years). An anterior approach was performed in 11 cases (39%): 5 for B1 fractures due to severe comminution (corpectomy and expandable vertebral cage with bone and BMP-2) and 6 for B2 fractures due to discal involvement on MRI (discectomy and iliac graft fusion). Regional kyphosis was significantly reduced (17.3° vs. 5.7°; p<0.05) and bone healing was obtained in all cases. There were no cases of postoperative infection. CONCLUSION Patients with flexion-distraction fractures without neurologic deficit can be eligible for minimally invasive percutaneous posterior fixation, associated if necessary to a minimally invasive anterior approach. This technique provides excellent bone healing with low surgical trauma and bleeding. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE The aim of this study was to evaluate midterm results after hybrid stabilization of unstable osteoporotic fractures of the thoracolumbar junction. METHODS This retrospective study was performed at a level I trauma center. A total of 113 patients aged 61 and older were stabilized using hybrid stabilization consisting of short-segmental posterior instrumentation and augmentation of the fractured vertebral body after suffering an unstable osteoporotic vertebral body fracture at the thoracolumbar spine. All patients were treated by hybrid stabilization. The primary outcome parameters were the ODI score and loss of reduction. Secondary radiological outcome parameters were the sagittal alignment parameters. RESULTS Seventy-two women and 41 men (74.6 ± 6.8 years) were included. Sixty-nine patients (61%) were re-evaluated after a mean of 48 months. Seventeen patients have died during the follow-up period (15%). A total of five in-patient complications were documented (4.4%). Additionally, 12 patients (17.4%) suffered from further osteoporotic vertebral body fractures affecting vertebral bodies of different levels. The average ODI score at the final follow-up was 29.9 (± 22.0). Thereby, 66.6% of all patients had low to moderate limitations. The average regional sagittal loss of reduction was 7.4% (± 5.6%). Loss of reduction was below 10° in 78% of the patients. There were statistically significant correlations between the loss of reduction and the ODI score, pelvic incidence and latest Cobb angle, and between the ODI scores and the lumbar lordosis. CONCLUSIONS The majority of patients had low or moderate limitations and low to moderate reduction loss. Thereby, high loss of reduction correlated directly with inferior outcomes.

Intermediate screws or kyphoplasty: Which method of posterior short-segment fixation is better for treating single-level thoracolumbar burst fractures? EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2018; 28:502-510. [PMID: 30448987 DOI: 10.1007/s00586-018-5822-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/20/2017] [Accepted: 11/04/2018] [Indexed: 10/27/2022]
Abstract
PURPOSE To compare intermediate screws (IS) with kyphoplasty (KP) in posterior short-segment fixation (PSSF) for patients with single-level thoracolumbar burst fractures. METHODS Between 2010 and 2016, 1465 patients were retrospectively reviewed; 48 patients were enrolled with a minimal follow-up of 2 years. Perioperative and functional outcomes were compared. The regional Cobb angle (CA) was included in radiographic analysis. Implant failures or CA correction loss over 10° were regarded as surgical failures. Multiple linear regression was performed to investigate the risk factors of kyphosis recurrence. RESULTS Fluoroscopic time (23.7 ± 3.6 vs. 79.3 ± 12.1 s, p < 0.001), operative time (109.6 ± 13.1 vs. 123.8 ± 19.0 min, p = 0.006) and blood loss (104.6 ± 34.9 vs. 129.1 ± 21.7 ml, p = 0.005) were all lower in the IS group. The KP group had lower Visual Analogue Scale scores (3.3 ± 0.9 vs. 2.7 ± 0.8, p = 0.028) and greater anterior body height (ABH) (30.3 ± 9.0 vs. 36.3 ± 11.0%, p = 0.044) after surgery, and less correction loss (5.6 ± 2.7 vs. 0.4 ± 1.2%, p < 0.001). Both groups had a CA correction loss of 4° with a 10% failure rate. The A3 Magerl subclassification, smaller preoperative ABH and smaller postoperative CA had positive correlations with CA correction loss. CONCLUSION PSSF with KP provides better back pain relief, greater ABH reduction and less correction loss, while IS has the advantages of less operative time, fluoroscopic time and blood loss. Magerl subclassification of burst fracture is a potential predictor for recurrent kyphosis. Reducing fractured vertebral body height rather than segmental curvature may be more important in PSSF.

Abstract
STUDY DESIGN consensus paper with systematic literature review. OBJECTIVE The aim of this study was to establish recommendations for treatment of thoracolumbar spine fractures based on systematic review of current literature and consensus of several spine surgery experts. METHODS The project was initiated in September 2008 and published in Germany in 2011. It was redone in 2017 based on systematic literature review, including new AOSpine classification. Members of the expert group were recruited from all over Germany working in hospitals of all levels of care. In total, the consensus process included 9 meetings and 20 hours of video conferences. RESULTS As regards existing studies with highest level of evidence, a clear recommendation regarding treatment (operative vs conservative) or regarding type of surgery (posterior vs anterior vs combined anterior-posterior) cannot be given. Treatment has to be indicated individually based on clinical presentation, general condition of the patient, and radiological parameters. The following specific parameters have to be regarded and are proposed as morphological modifiers in addition to AOSpine classification: sagittal and coronal alignment of spine, degree of vertebral body destruction, stenosis of spinal canal, and intervertebral disc lesion. Meanwhile, the recommendations are used as standard algorithm in many German spine clinics and trauma centers. CONCLUSION Clinical presentation and general condition of the patient are basic requirements for decision making. Additionally, treatment recommendations offer the physician a standardized, reproducible, and in Germany commonly accepted algorithm based on AOSpine classification and 4 morphological modifiers.

Abstract
The present study investigated the efficacy of percutaneous kyphoplasty and alendronate sodium on thoracolumbar vertebral fracture, and the risk factors leading to the recurrence of fracture. In the present study, a total of 80 patients with thoracolumbar vertebral fracture who were admitted to the Affiliated Jiangyin Hospital of Southeast University Medical College between January 2014 and March 2016 for combination treatment of percutaneous kyphoplasty and alendronate sodium were enrolled. According to the recurrence of fracture, the patients were divided into two groups, the observation group (patients with fracture recurrence, n=40) and control group (patients with no fracture recurrence, n=40). All patients participated in a 1-year follow-up. The recurrence of fracture and the site of fracture were identified through the clinical symptoms and examination of the spine using magnetic resonance imaging. In addition, comparisons of the time of alleviation in numbness of lower limb and that in pains in waist and legs were carried out. Furthermore, statistics on the adverse reactions during intervention in the two groups were also collected; changes in visual analogue scale (VAS) and Oswestry Disability Index (ODI) of pains at different time points in two groups were also observed. One-way analysis and multivariate analysis were performed to identify the relevant risk factors. Alleviation time in numbness of lower legs in patients of the control group was significantly earlier than that in the observation group (P<0.05) and the alleviation time in pains of the waist and legs of patients in the control group was also significantly earlier than that in the observation group (P<0.05). Furthermore, the incidence rates of abdominal pain, diarrhea, constipation and hypocalcemiain in the control group were also significantly lower compared with those in the observation group (P<0.05). One week, one month and one year after operation, the scores of VAS of pains and ODI in the control group were significantly lower compared with those in the observation group in the same period (P<0.05). Lower preoperative bone density and exosmosis of bone cement in treatment were the independent risk factors leading to the recurrence of fracture. For patients with thoracolumbar vertebral fracture who received the combination treatment of percutaneous kyphoplasty and alendronate sodium, there underlies an important correlation between the recurrence rate of fracture and the preoperative bone density as well as the exosmosis of bone cement in operation.

BACKGROUND This study aimed to compare the accuracy of screw placement between open pedicle screw fixation and percutaneous pedicle screw fixation (MIS) for the treatment of thoracolumbar spine fractures (TSF). METHODS forty-nine patients with acute TSF who were treated with transpedicular screw fixation from January 2013 to December 2016 were retrospectively reviewed. The patients were divided into Open and MIS groups. Laminectomy was performed in either group if needed. The accuracy of the screw placement, the evolution of the Cobb sagittal angle postoperatively and at 12-month follow-up and the neurological status were recorded. AO type of fracture and TLICS score were also recorded. RESULTS Mean age was 42 years old. Mean TLICS score was 6.29 and 5.96 for open and MIS groups respectively. Twenty-five MIS and 24 open surgeries were performed, and 350 (175 in each group) screws were inserted (7.14 per patient). Twenty-four and 13 screws were considered "out" in the open and MIS groups respectively (Odds ratio 1.98. 0.97-4,03 P=0.056). The Cobb sagittal angle went from 13.3º to 4.5º and from 14.9º to 8.2º in the Open and MIS groups respectively (both P<0.0001). Loss of correction at 12-month follow-up was 3.2º and 4.2º for the open and MIS groups, respectively. No neurological worsening was observed. CONCLUSIONS For the treatment of acute thoracolumbar fractures, the MIS technique seems to achieve similar results to the open technique in relation to neurological improvement and deformity correction, while placing the screws more accurately.

Abstract
PURPOSE The aim of the current study is to analyze perioperative data and complications of open vs. percutaneous dorsal instrumentation after dorsal stabilization in patients suffering from fractures of the thoracic or lumbar spine. METHODS In the time period from 01/2007 to 06/2009, open surgical approach was used for dorsal stabilization. The percutaneous surgical approach was used from 05/2009 to 03/2014. In every time period, all types of fractures were treated only by open or by percutaneous approach, respectively, to avoid any selection bias. Retrospectively, epidemiological data, complications and perioperative data were documented and statistically analyzed. RESULTS A total of 491 patients met the inclusion criteria. Open surgery procedure was carried out on 169 patients, and percutaneous surgery procedure was carried out on 322 patients. Fracture level ranged from T1 to L5, and fractures were classified types A, B, and C. In 91.4% of all patients, no complication occured following dorsal stabilization after traumatic spine fracture during their hospital stay. However, 42 complications related to dorsal stabilization have been documented during the hospital stay. The complication rate was 14.8% if open surgical approach has been used and was significantly reduced to 5.3% using percutaneous surgical approach. Post-operative hospital stay was also reduced significantly using the percutaneous surgical approach. CONCLUSIONS According to the current study, percutaneous dorsal stabilization of the spine could also be safely used in trauma cases and is not restricted to degenerative spinal surgery.
