Abstract Introduction: Posterior short segment pedicle screw fixation is considered the most common way for management of unstable thoracolumbar spine fracture. This study is aiming to evaluate the efficacy of both posterior short same segment and posterior short segment pedicle screw fixation on postoperative kyphotic angle and pain dense score in thoracolumbar fractures. Methods: This is a Prospective study of 32 patients with single level thoracolumbar spine fracture between June 2011 and May 2014. Patients were divided randomly into 2 groups, one of them was submitted to short same segment posterior pedicle screw fixation with mean age 31.25+9.25ys, while the other group submitted to short segment posterior pedicle screw fixation with mean age 29.18+9.65ys. Cobb method and Denis work scale were used to assess kyphotic angle and pain score respectively on admission, during follow up period and after one year postoperatively. Results: The short same segment type of operation showed improvement in correction in kyphotic angle deformity at the end of follow up period although this improvement was not statistically significant compared to short segment type. The short same segment patients showed statistically significant improvement as regard pain Denis score among those patients treated by short segment fixation. Conclusion: In this study short same segment posterior pedicle screw fixation is more efficient in postoperative pain reduction than short segment posterior pedicle screw fixation.

<p>The aim of this study was to evaluate the efficacy of inclusion of the fractured vertebra in short segment fixation in terms of clinical and the radiological outcomes in unstable thoracolumbar junction burst fractures at a minimum of 1 year follow-up. Records of 52 patients (age: 21-50 years) with thoracolumbar burst fracture (T10–L2) in Magerl Type A fractures underwent posterior pedicle screw fixation including the fractured vertebra. Clinical parameters were back pain using Visual Analogue Score (VAS) and disability using Oswestry disability index (ODI), neurological deficit (using ASIA grade) and radiologic parameters (Cobb angle, the kyphotic deformation and vertebral height) were measured before surgery and at 3, 6 and 12 months  post-operatively. The presence of screw breakage, screw pullout, peri-implant loosening, and rod breakage were considered as criteria for implant failure. The majority of fractures resulted due to falls (31 cases), and the remaining cases resulted from car accidents (21 cases). The fractured vertebral body level was L1, T12, L2, T11, and T10 in 23, 17, 6, 4 and 2 cases and achieved satisfactory clinical outcomes according to the modified Mcnab criteria 18, 25, 6 and 3 cases were considered to have excellent, good, fair, and poor outcome. The mean kyphotic angle at pre-, post-operative and final follow-up was 13.5 ± 6.3, 13.4 ± 4.3, 8.5 ± 6.  The average loss of kyphosis correction was 6.4 ± 5.2° at the final follow-up. The mean pre- and post-operative kyphotic deformation of vertebral body was 5.1 ± 3.2, 4.8 ± 2.3 and at final follow-up was 4.5 ± 4.0 (p&gt;0.05). The mean anterior and posterior vertebral height also showed significant improvements post-operatively, which were maintained at the final follow-up. The mean ODI and VAS scores at the end of 1 year were 17.4%, 1.7 respectively. There was no case of major complication after surgery and during the follow-up period. In conclusion, reduction of unstable thoracolumbar junction burst fracture can be achieved and maintained with the use of short-segment pedicle screw fixation including the fractured vertebra, avoiding the need for anterior reconstruction.</p><p> </p>

Abstract Background Treatment of congenital hemivertebra is challenging and data on long-term follow-up (≥ 5 years) are lacking. This study evaluated the surgical outcomes of posterior thoracolumbar hemivertebra resection and short-segment fusion with pedicle screw fixation for treatment of congenital scoliosis with over 5-year follow-up. Methods This study evaluated 27 consecutive patients with congenital scoliosis who underwent posterior thoracolumbar hemivertebra resection and short-segment fusion from January 2007 to January 2015. Segmental scoliosis, total main scoliosis, compensatory cranial curve, compensatory caudal curve, trunk shift, shoulder balance, segmental kyphosis, and sagittal balance were measured on radiographs. Radiographic outcomes and all intraoperative and postoperative complications were recorded. Results The segmental main curve was 40.35° preoperatively, 11.94° postoperatively, and 13.24° at final follow-up, with an average correction of 65.9%. The total main curve was 43.39° preoperatively, 14.13° postoperatively, and 16.06° at final follow-up, with an average correction of 60.2%. The caudal and cranial compensatory curves were corrected from 15.78° and 13.21° to 3.57° and 6.83° postoperatively and 4.38° and 7.65° at final follow-up, with an average correction of 69.2% and 30.3%, respectively. The segmental kyphosis was corrected from 34.30° to 15.88° postoperatively and 15.12° at final follow-up, with an average correction of 61.9%. A significant correction (p < 0.001) in segmental scoliosis, total main curve, caudal compensatory curves and segmental kyphosis was observed from preoperative to the final follow-up. The correction in the compensatory cranial curve was significant between preoperative and postoperative and 2-year follow-up (p < 0.001), but a statistically significant difference was not observed between the preoperative and final follow-up (p > 0.001). There were two implant migrations, two postoperative curve progressions, five cases of proximal junctional kyphosis, and four cases of adding-on phenomena. Conclusion Posterior thoracolumbar hemivertebra resection after short-segment fusion with pedicle screw fixation in congenital scoliosis is a safe and effective method for treatment and can achieve rigid fixation and deformity correction.

Introduction: Blood loss with spinal surgery is common potential cause of morbidity and often requires blood transfusion. Tranexamic acid (TXA), is effective in reducing bleeding in patients undergoing knee arthroplasty. TXA used in spine surgery studies have included different cases leading to inconsistence of surgical procedures. Purpose of this prospective observational study was to examine effect of TXA decreasing bleeding in short segment pedicle screw fixation for thoracolumbar fractures. Methods: 38 patients' undergoing short segment pedicle screw for thoracolumbar fractures were enrolled in study from July to August 2013. There were 28 male and 10 female patients, with an average age of 36.5 years. Patients received 10 mg/kg of TXA or a control 30 minutes intravenously before skin incision and 3 hours post-operative and oral medication for three days. Intraoperative bleeding was estimated by weighing surgical sponges, blood collected by suction container and by subtracting all irrigation fluid. Postoperative bleeding was measured from volume in vacuum drainage bag. Results: Twenty (20) patients were in control group and eighteen(18) to TXA group. There were no statistical differences between groups in terms of age, gender, co-morbidities, and operating time, preoperative Hemoglobin, PT and INR. Intra-operative bleeding in TXA group was significant than in control group. Post-operative drainage and Hemoglobin in first 48 h was reduced compared with placebo in TXA group. Need for post-operative transfusion was nil in TXA group. Conclusions: Administration of TXA before surgery significantly reduces perioperative bleeding in patients undergoing short segment pedicle screw fixation for thoracolumbar spine fractures.  Keywords: bleeding; spinal surgery; tranexamic acid.

Abstract Background: Correction loss and hardware failure of short segment posterior pedicle screw fixation in treatment of thoracolumbar unstable burst fracture have been remaining a main concern. Several authors have introduced the procedures to solve these limitations including transforaminal interbody fusion (TIF). The purposes of this study were to evaluate the progressive kyphosis and implant failure of short-segment pedicle screw fixation combined with transforaminal interbody fusion in treatment of unstable thoracolumbar burst fracture.Methods: The retrospective study were enrolled in the patients with isolated unstable thoracolumbar burst fractures, Denis type IIB who were treated by posterior short fixation with TIF between January 2013 to January 2017. Patients were followed up for a minimum of one and half year. For evaluation of correction loss, % loss of anterior vertebral body heights (%AVB), vertebral kyphotic angle (VA) and regional kyphotic angle (RA) were collected preoperatively, postoperatively and at final follow-up. The hardware failure was assessed on radiological images at last follow-up. Results: There were 36 patients who met the inclusion criteria with a mean follow-up duration of 53 months. The mean correction loss of %AVB, VA and, RA were 10.2%, 2.9o and 5.6o, respectively. There were 6 patients (16.7%) with hardware failure at final follow-up. Conclusions: Short-segment posterior pedicle screw fixation with TIF using bone chip graft hasn’t prevented completely the hardware failure and progressive kyphosis in treatment of unstable thoracolumbar burst fracture.

Initial Clinical Experience

Object Surgical intervention for thoracolumbar burst fractures is indicated for patients with neurological deficits and/or evidence of severe spinal instability. The goals of surgery are decompression, deformity correction, and stabilization. Nevertheless, the optimal surgical strategy to achieve these goals remains a subject of debate. Short-segment pedicle screw fixation is associated with a 20 to 50% incidence of pedicle screw failure and progressive spinal deformity. Initial biomechanical and clinical studies have shown that reinforcement of short-segment pedicle screw fixation with vertebroplasty improves spinal stability and decreases instrument failure rates. In this study, the authors describe their initial clinical experience with kyphoplasty used to augment short-segment pedicle screw fixation of traumatic lumbar burst fractures. Methods Five patients with traumatic burst fractures of the lumbar spine were included in this retrospective review of patients treated for this disorder at the University of California, San Diego and the University of California, San Francisco between 2002 and 2004. All patients underwent transpedicular kyphoplasty and short-segment pedicle screw fixation. The mean follow-up period was 10.6 months (range 6–18 months). All patients underwent short-segment pedicle screw fixation reinforced with polymethyl methacrylate kyphoplasty. The preoperative, postoperative, and follow-up plain x-ray films were evaluated. Radiographic analysis included measurements of kyphotic angulation, anterior vertebral body height, and evidence of bone fusion. Clinical evaluation was performed postoperatively and at follow-up review. Conclusions Based on the authors' initial experience, kyphoplasty supplementation may improve the long-term integrity of short-segment pedicle screw constructs and allow for improved rates of fusion and better clinical outcomes in patients with traumatic lumbar burst fractures.
