Abstract
OBJECTIVE Skipped multifocal pyogenic spondylodiscitis is a rare presentation of spinal infection. In our institution, we used the single posterior approach for circumferential debridement and anterior reconstruction with fibular allograft for treatment. This study aimed to ascertain the viability and reliability of this technique for these difficult cases. METHODS Nine patients with skipped pyogenic spondylodiscitis who received our treatment method from January 2012 to December 2019 were enrolled in this study. Visual analog scale scores, causative agents, laboratory data, comorbidities, and complications were recorded. The patients' clinical conditions were evaluated based on modified Brodsky's criteria, visual analogue scale, and Oswestry Disability Index. RESULTS All the patients achieved infection eradication without repeat surgical treatment. The average visual analog scale score was 8.4 (range, 8-9) before operation, which decreased to 1.9 (range, 1-3) 1 year after the surgery. No patient experienced severe complications such as neurologic deterioration or fixation failure. All patients achieved a good or excellent outcome based on modified Brodsky's criteria. The Oswestry Disability Index improved from 80.4 (range, 70-86) preoperatively to 25.1 (range, 20-32) 1 year after the surgery. CONCLUSIONS In our case series, good clinical outcomes and high successful rates could be achieved through the single-stage posterior-only approach. This could be considered an alternative method to manage patients with skipped pyogenic spondylodiscitis.

Abstract
Objective To evaluate the clinical effects of the posterior unilateral approach with 270° spinal canal decompression and three-column reconstruction using double titanium mesh cage (TMC) for thoracic and lumbar burst fractures. Materials and methods From May 2013 to May 2018, 27 patients with single-level thoracic and lumbar burst fractures were enrolled. Every patient was followed for at least 18 months. Demographic data, neurologic status, back pain, canal compromise, anterior body compression, operative time, estimated blood loss and surgical-related complications were evaluated. Radiographs were reviewed to assess deformity correction, anterior body height correction, bony fusion and TMC subsidence. Results The average preoperative percentages of canal compromise and anterior body height compression were 58.4% and 50.5%, respectively. All surgeries were successfully completed in one phase, the operative time was 151.5 ± 25.5 min (range: 115-220 min), the estimated blood loss was 590.7 ± 169.9 ml (range: 400-1,000 ml). Neurological function recovery was significantly improved except for 3 grade A patients. The preoperative visual analog scale (VAS) scores for back pain were significantly decreased compared with the values at the last follow-up (P = 0.000). The correct deformity angle was 12.4 ± 4.7° (range: 3.9-23.3°), and the anterior body height recovery was 96.7%. The TMC subsidence at the last follow-up was 1.3 ± 0.7 mm (range: 0.3-3.1 mm). Bony fusion was achieved in all patients. Conclusion The posterior unilateral approach with 270° spinal canal decompression and three-column reconstruction using double TMC is a clinically feasible, safe and alternative treatment for thoracic and lumbar burst fractures.

Abstract
Abstract
Background
Skipped multifocal spinal tuberculosis (TB) is an atypical presentation of spinal TB. Surgical treatment for these unusual cases remains a challenge for spine surgeons. In our institute, we used single-stage circumferential debridement and anterior reconstruction with fibular allograft followed by posterior instrumentation through posterior-only approach for these patients. This study aimed to determine the efficacy and feasibility of this technique.
Methods
Twelve patients with skipped multifocal spinal TB who received our treatment method from January 2012 to June 2020 were enrolled in this study. The visual analog score (VAS), laboratory data, comorbidities, complications, and neurologic status based on Frankel scale were recorded. The patients’ clinical conditions were evaluated based on modified Brodsky’s criteria and Oswestry Disability Index (ODI).
Results
All the patients were infection free at the end of the treatment. The average VAS score was 7.5 (range, 7–8) before surgery and decreased to 2.1 (range, 1–3) one year postoperatively. No one experienced any severe complications such as neurologic deterioration, fixation failure, or bone graft dislodgement. Out of the three patients requiring debridement surgery, two had wound infection and one had seroma formation. The ODI score improved from 76.8 (range, 70–84) preoperatively to 25.5 (range, 22–28) one year after surgery. All patients achieved good or excellent outcome based on modified Brodsky’s criteria one year postoperatively.
Conclusions
In our study, the patients could achieve a good clinical outcome. This technique could be an alternative for patients with skipped spinal TB.

The Efficiency and Reliability of Minimally Invasive Anterior Corpectomy and Percutaneous Posterior Stabilization for the Treatment of Unstable Thoracolumbar Burst Fractures. World Neurosurg 2022; 167:e310-e316. [PMID: 35961588 DOI: 10.1016/j.wneu.2022.08.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Revised: 08/01/2022] [Accepted: 08/02/2022] [Indexed: 11/23/2022]
Abstract
OBJECTIVE The purpose of this study was to evaluate the radiological and clinical outcomes of minimally invasive anterior corpectomy and percutaneous posterior stabilization for treating unstable thoracolumbar burst fractures. METHODS Patients with unstable thoracolumbar burst fractures who underwent minimally invasive anterior corpectomy and percutaneous posterior stabilization between 2012 and 2019 at a tertiary hospital were enrolled. Radiological outcomes such as endplate subsidence and fusion status were identified on preoperative and postoperative plain radiographs and computed tomography images. Preoperative and postoperative neurological statuses were evaluated using the American Spinal Injury Association impairment scale. Furthermore, operation-related parameters were analyzed. RESULTS In total, 21 patients (mean follow-up period, 21.7 months) were included in this study. Of them, 17 (80.95%) patients exhibited complete fusion according to the Bridwell's criteria at the final follow-up, and only 1 patient exhibited nonunion at the surgical level. Endplate subsidence was observed in 6 (28.57%) patients; however, there were no definite symptoms that would have necessitated a revision surgery. Of 15 patients with preoperative neurological impairment, 7 exhibited neurological improvement during follow-up. None of the patients experienced postoperative neurological deterioration. Regarding operation-related parameters, the mean operative time and intraoperative blood loss were 266.19 ± 51.54 min and 520.71 ± 190.86 ml, respectively. The mean length of hospital stays and days to postoperative ambulation were 12.14 and 4.20 days, respectively. CONCLUSIONS Minimally invasive anterolateral corpectomy with percutaneous pedicle screw fixation is a reliable surgical treatment option for unstable thoracolumbar burst fractures.

Abstract
OBJECTIVE Because of the challenging anatomic location, corpectomies are performed less often at the fourth lumbar vertebral body than at other levels. Our objective was to review the literature of L4 corpectomy and anterior column reconstruction. METHODS A literature search in the Medline/PubMed database was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to identify all relevant cases and cases series describing corpectomies of the L4 vertebral body using "lumbar" AND "corpectomy" as search terms. We present an illustrative case to describe the technique. RESULTS We identified 18 articles with 30 patients who met the search criteria. Including our case illustration, the most common approach used was the lateral retroperitoneal approach (n = 17, 54.8%), of which 8 (26.7%) were performed via a transpsoas approach. Seven (23%) patients underwent corpectomy through a posterior approach, 4 (12.9%) through an anterior retroperitoneal approach, and 3 (10%) through combined anterior and lateral retroperitoneal. The overall complications rate was 19.3% including 1 case each of femoral nerve injury and iatrogenic lumbar nerve root injury. CONCLUSIONS Corpectomies of the L4 vertebral body are challenging. None of the various approaches described clearly demonstrates any superiority in mitigating the risk of neural complications. Decision making about which surgical approach to use should be based on patient-specific characteristics.

Abstract
STUDY DESIGN Retrospective observational. OBJECTIVES This study aimed to document the safety and efficacy of lumbar corpectomy with reconstruction of anterior column through posterior-only approach in complete burst fractures. METHODS In this retrospective study, we analyzed complete lumbar burst fractures treated with corpectomy through posterior only approach between 2014 and 2018. Clinical and intraoperative data including pre and post-operative neurology as per the ISNCSCI grade, VAS score, operative time, blood loss and radiological parameters, including pre and post-surgery kyphosis, height loss and canal compromise was assessed. RESULTS A total of 45 patients, with a mean age of 38.89 and a TLICS score 5 or more were analyzed. Preoperative VAS was 7-10. Mean operating time was 219.56 ± 30.15 minutes. Mean blood loss was 1280 ± 224.21 ml. 23 patients underwent short segment fixation and 22 underwent long segment fixation. There was no deterioration in post-operative neurological status in any patient. At follow-up, the VAS score was in the range of 1-3. The difference in preoperative kyphosis and immediate post-operative deformity correction, preoperative loss of height in vertebra and immediate post-operative correction in height were significant (p < 0.05). CONCLUSION The posterior-only approach is safe, efficient, and provides rigid posterior stabilization, 360° neural decompression, and anterior reconstruction without the need for the anterior approach and its possible approach-related morbidity. We achieved good results with an all posterior approach in 45 patients of lumbar burst fracture (LBF) which is the largest series of this nature.

Abstract
Purpose Approaches for lumbar corpectomies can be roughly categorized into anterolateral (AL) and posterolateral (PL) approaches. It remains controversial to date whether one approach is superior to the other, and no comparative studies exist for the two approaches for lumbar corpectomies. Methods A systematic review of the literature was performed through a MEDLINE/PubMed search. Studies and case reports describing technique plus outcomes and possible complications were included. Thereafter, estimated blood loss (EBL), length of operation (LOO), utilized implants, neurological outcomes, complication rates, and reoperation rates were analyzed. Results A total of 64 articles reporting on 702 patients including 513 AL and 189 PL corpectomies were included in this paper. All patients in the PL group were instrumented via the same approach used for corpectomy, while in the AL group the majority (68.3%) of authors described the use of an additional approach for instrumentation. The EBL was higher in the AL group (1393 ± 1341 ml vs. 982 ± 567 ml). The LOO also was higher in the AL group (317 ± 178 min vs. 258 ± 93 min). The complication rate (20.5% vs. 29.1%, p = 0.048) and the revision rate (3.1% vs. 9.5%, p = 0.004) were higher in the PL group. Neurological improvement rates were 43.8% (AL) vs. 39.2% (PL), and deterioration was only noted in the AL group (6.0%), while 50.2% (AL) and 60.8% (PL) showed no change from initial presentation to the last follow-up. Conclusion While neurological outcomes of both approaches are comparable, the results of the present review demonstrated lower complication and revision rates in anterolateral corpectomies. Nevertheless, individual patient characteristics must be considered in decision-making.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE The aim of this study is to evaluate the clinical, neurological, and radiological outcomes of posterior vertebral column resection (PVCR) technique for treatment of thoracic and thoracolumbar burst fractures. METHODS Fifty-one patients (18 male, 33 female) with thoracic/thoracolumbar burst fractures who had been treated with PVCR technique were retrospectively reviewed. Preoperative and most recent radiographs were evaluated and local kyphosis angle (LKA), sagittal and coronal spinal parameters were measured. Neurological and functional results were assessed by the American Spinal Injury Association (ASIA) Impairment Scale, visual analogue scale score, Oswestry Disability Index, and Short Form 36 version 2. RESULTS The mean age was 49 years (range 22-83 years). The mean follow-up period was 69 months (range 28-216 months). Fractures were thoracic in 16 and thoracolumbar in 35 of the patients. AO spine thoracolumbar injury morphological types were as follows: 1 type A3, 15 type A4, 4 type B1, 23 type B2, 8 type C injuries. PVCR was performed in a single level in 48 of the patients and in 2 levels in 3 patients. The mean operative time was 434 minutes (range 270-530 minutes) and mean intraoperative blood loss was 520 mL (range 360-1100 mL). The mean LKA improved from 34.7° to 4.9° (85.9%). For 27 patients, the initial neurological deficit (ASIA A in 8, ASIA B in 3, ASIA C in 5, and ASIA D in 11) improved at least 1 ASIA grade (1-3 grades) in 22 patients (81.5%). Solid fusion, assessed with computed tomography at the final follow-up, was achieved in all patients. CONCLUSION Single-stage PVCR provides complete spinal canal decompression, ideal kyphosis correction with gradual lengthening of anterior column together with sequential posterior column compression. Anterior column support, avoidance of the morbidity of anterior approach and improvement of neurological deficit are the other advantages of the single stage PVCR technique in patients with thoracic/thoracolumbar burst fractures.

Abstract
STUDY DESIGN A single-institution retrospective study of a cohort of patients who underwent internal fixation spine surgery for thoracolumbar burst fracture (TLBF). OBJECTIVE To observe the imaging manifestations of intervertebral disc changes in TLBF, to analyze the relationship between the degree of disc injury and the Cobb angle increase. METHODS We retrospectively analyzed the data of patients who underwent short-segment pedicle screw instrumentation in the spinal surgery department of a single hospital between January 2014 and December 2017 (n = 90). According to the magnetic resonance imaging characteristics of the superior intervertebral disc tissue of the injured vertebrae before the operation, the intervertebral disc injury was divided into three types, which was used for group allocation: group A, uninjured intervertebral disc group; group B, mild intervertebral disc injury group; and group C, severe intervertebral disc injury group. The main imaging results of the three groups Cobb, IVA, IHI, AHIV, and VAS were compared among groups. RESULTS Ninety patients were included in the study (n = 38, 32, and 20, in groups A, B, and C, respectively). There was no statistically significant difference in demographics among the three groups (p > .05). 1-year post-surgery, the Cobb angle in group C differed significantly from that in groups A and B (p < .01). There was a significant difference in Cobb angle between groups A and B after internal fixation was removed for 6 months. At 1-year post-surgery, the IHI group C differed significantly from groups A and B (p < .01), while groups A and B were similar (p = .102); however, at 6 months after the internal fixation was removed, the IHI differed significantly between these two groups, also the AHIV between groups A and B was statistically significant (p < .01). The VAS pain score was similar among the three groups. Pearson's test showed that the increase in the Cobb angle was moderately correlated with IVA and IHI, and weakly correlated with AHIV. CONCLUSION For TLBF with an intervertebral disc injury, the presurgical degree of intervertebral disc injury is the main reason for the post-surgery increase in the Cobb angle. Thus, diagnosis and treatment of this kind of patient require attention to the risk of spinal deformity.

Abstract
BACKGROUND We evaluate the feasibility of a single-stage posterior corpectomy and circumferential arthrodesis with the aid of spinal navigation for the treatment of traumatic thoracolumbar burst fractures. METHODS This was a single-center, retrospective study. Demographics, clinical, and radiologic data of 19 patients who underwent surgery at our institution for thoracolumbar burst fractures between 2016 and 2019 were collected. All patients enrolled in the present study underwent surgery by means of posterior fixation and transpedicular corpectomy with the aid of an intraoperative image-guided neuronavigation system. RESULTS Postoperative correction of the vertebral height ratio was achieved in all cases, with an average increase of 23.6% (p = 0.0005). No statistical differences (p = 0.9) were found comparing 1- and 3-month postoperative CT scans, in relation to vertebral height ratio. A statistically significant difference was found between the pre- and postoperative kyphotic angles for the thoracolumbar and lumbar segments (p = 0.0018 and 0.005, respectively), but no difference was found between kyphotic angles at the 3-month follow-up. A unilateral approach was performed on 15 patients (79%), while 4 cases (21%) required a bilateral laminectomy. We did not observe any significant intraoperative complication. CONCLUSION Single-stage posterior corpectomy and fixation is a safe and effective approach for thoracic and lumbar burst fractures. It provides excellent 360-degree reconstruction in a single surgical stage with satisfactory results in terms of kyphosis reduction, biomechanical stability, and reduced invasiveness. Spinal navigation represents a fundamental tool to overcome some anatomical limits of the presented technique.

Abstract
Objective To compare the clinical results of two surgical techniques, Wiltse approach and conventional transforaminal interbody fusion, for the treatment of unstable thoracolumbar fracture associated with traumatic intervertebral disc lesion (TIDL). Methods A total of 76 patients with unstable thoracolumbar fracture associated with TIDL treated by posterior pedicle screw fixation and transforaminal thoracolumbar interbody fusion from June 2010 and July 2016 were reviewed retrospectively. These patients including 48 male and 28 female patients were divided into Wiltse approach transforaminal thoracolumbar interbody fusion (W‐TLIF) group (n = 38) and conventional transforaminal thoracolumbar interbody fusion (C‐TLIF) group (n = 38). Patients were followed up for about 33 months. Clinical and radiological records, kyphotic angle, fractured vertebral body height, visual analogue score (VAS), Oswestry Disability Index (ODI), complications, neurological improvement and fusion rate were compared between two groups. Results All patients underwent posterior surgery successfully. Blood loss, operation time and hospital stay in the W‐TLIF group was 437.84 ± 143.98 ml, 118.64 ± 20.55 min and 12.32 ± 2.87 days, respectively. While those parameters in the C‐TLIF group was 862.70 ± 300.24 ml, 141.35 ± 31.72 min and 15.51 ± 2.08 days, respectively. Average operation time and hospital stay time were significantly shorter, and blood loss was significantly less in the W‐TLIF group than in the C‐TLIF group (P < 0.05). VAS and ODI in the W‐TLIF group were significantly less than those in the C‐TLIF group at 1 week after operation and final follow‐up. The kyphotic angle and vertebral body height were improved. There was 1–2 grade improvement in patients with neurological deficit. Thirty‐three patients in the W‐TLIF group and 32 patients in the C‐TLIF group had achieved fusion during follow‐up. No internal fixation failure was observed in two groups. Conclusions The both techniques of W‐TLIF and C‐TLIF were feasible and effective for unstable thoracolumbar fracture with TIDL. Compare to C‐TLIF, The technique of W‐TLIF was a relatively less invasive way to decompress the neural elements and an easy method to reconstruct the anterior column using the same posterior approach.

Abstract
CASE The case describes a 59-year-old male patient who suffered from a solitary metastasis of unknown origin in the L1 vertebra. Owing to the instability, a corpectomy and posterior fixation with the expandable cage implantation was performed. However, the disease progressed, which required additional nonadjacent corpectomy and cranial elongation of the construct with implantation of the additional expandable cage at the level Th11. CONCLUSION In such complex pathology, two single-level nonadjacent corpectomies and expandable cage implantations present a surgical solution that may provide a satisfactory outcome.

Abstract
Objective To evaluate the surgical outcomes of partial pedicle subtraction osteotomy (PPSO) in patients with thoracolumbar fractures and compare the outcomes of PPSO for burst fractures with those for posttraumatic kyphosis (PTK).
Methods From June 2013 to May 2019, 20 consecutive adult patients underwent PPSO for thoracolumbar fractures at the levels of T10 to L2. Of these patients, 10 underwent surgery for acute fractures (burst fractures), and 10 for sequelae of thoracolumbar fractures (PTK). Outcomes of PPSO were evaluated and compared between the groups.
Results Twenty patients (each 10 patients of burst fractures and PTK) with a mean age of 64.7±11.1 years were included. The mean follow-up period was 21.8±11.0 months. The mean correction of the thoracolumbar angle was -34.9°±18.1° (from 37.8°±20.5°preoperatively to 2.8°±15.2° postoperatively). The mean angular correction at the PPSO site was -38.4°±13.6° (from 35.5°±13.6° preoperatively to -2.9°±14.1° postoperatively). The mean preoperative sagittal vertical axis was 93.5±6.7 cm, which was improved to 37.6±35.0 cm postoperatively. The mean preoperative kyphotic angle at the PPSO site was significant greater in patients with PTK (44.8°±7.2°) than in patients with burst fractures (26.2°±12.2°, p=0.00). However, the mean postoperative PPSO angle did not differ between the two groups (-5.9°±15.7° in patients with burst fractures and 0.2°±12.4° in those with PTK, p=0.28). The mean angular correction at the PPSO site was significantly greater in patients with PTK (-44.6°±10.7°) than in those with burst fractures (-32.1°±13.7°, p=0.04). The mean operation time was 188.1±37.6 minutes, and the mean amount of surgical bleeding was 1030.0±533.2 mL. There were seven cases of perioperative complications occurred in five patients (25%), including one case (5%) of neurological deficit. The operation time, surgical bleeding, and complication rates did not differ between groups.
Conclusion In cases of burst fracture, PPSO provided enough spinal cord decompression without corpectomy and produced sagittal correction superior to that achieved with corpectomy. In case of PTK, PPSO achieved satisfactory curve correction comparable to that achieved with conventional PSO, with less surgical time, less blood loss, and lower complication rates. PPSO could be a viable surgical option for both burst fractures and PTK.

Dual expandable interbody cage utilization for enhanced stability in vertebral column reconstruction following thoracolumbar corpectomy: A report of two cases. NORTH AMERICAN SPINE SOCIETY JOURNAL (NASSJ) 2021; 8:100081. [PMID: 35141646 PMCID: PMC8819912 DOI: 10.1016/j.xnsj.2021.100081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/12/2021] [Revised: 09/22/2021] [Accepted: 09/22/2021] [Indexed: 11/22/2022]
Abstract
Background Thoracolumbar corpectomies require adequate anterior column spinal reconstruction, often achieved through a single static or expandable cage. Patients with larger vertebrae, or those who require a larger footprint of reconstruction placed via a posterior approach are technically challenging. The aim of this report was to describe a novel approach for reconstruction using two smaller expandable cages following corpectomy, in the setting of tumor and trauma. Methods These technical reports illustrate a novel intraoperative technique with reconstruction via dual expandable cages implanted posteriorly from a bilateral costotransversectomy and transpedicular approaches. Due to the smaller size of each cage, implantation in the vertebral column was achieved with minimal retraction of the spinal cord. Results Two patients underwent urgent corpectomy in the thoracolumbar spine using this technique. Clinical improvement was evident post-surgery and adequate spine stabilization was confirmed radiographically without cage migration or subsidence, at up to one year of clinical follow up. No iatrogenic neurological deficits were reported in each case as well. Conclusion To the authors’ knowledge, this is the first report of a corpectomy where this surgical technique was implemented in the thoracolumbar spine. This technique created a large footprint of reconstruction with less retraction on the spinal cord during surgery, reducing the potential for neurological complications. An alternative strategy is to place a larger footprint reconstruction through an anterior or lateral approach; however, these techniques also have potential morbidity which require consideration.

Abstract
Objective To investigate the effectiveness of limited middle and posterior column osteotomy via transvertebral space approach in treatment of old thoracolumbar compression fracture. Methods A clinical data of 47 patients with old thoracolumbar compression fractures, who met the selection criteria between January 2010 and March 2018, was retrospectively analyzed. Twenty-five patients (group A) underwent the limited middle and posterior column osteotomy via transvertebral space approach, and 22 patients (group B) underwent the pedicle subtraction osteotomy (PSO). There was no significant difference in gender, age, cause of injury, time from injury to operation, fracture segment, and preoperative Cobb angle, sagittal vertical axis (SVA), visual analogue scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and Oswestry disability index (ODI) between the two groups ( P>0.05). The operation time, intraoperative blood loss, and postoperative complications, as well as postoperative Cobb angle, SVA, VAS score, JOA score, ODI and the differences of all indexes between pre- and post-operation were recorded and compared between the two groups. The neurological function was evaluated by Frankel scale. Results The operations of both groups were successfully completed. The operation time and intraoperative blood loss in group A were significant lower than those in group B ( P<0.05). All incisions healed by first intetion. All patients were followed up 23-27 months (mean, 24.2 months) in group A and 24-28 months (mean, 24.8 months) in group B. At last follow-up, the VAS score, JOA score, ODI, Cobb angle, and SVA of the two groups were compared with those before operation, and the differences were significant ( P<0.05). There was no significant difference between the two groups ( P>0.05) in the indexes at last follow-up and the difference between pre- and post-operation. The lower extremity neurological symptoms (Frankel grade D) in 3 patients of group A before operation relieved (Frankel grade E) at last follow-up. The other patients were Frankel grade E. At last follow-up, CT showed bony fusion in the grafted area without any complications such as failure of internal fixation or pseudarthrosis. Conclusion For patients with old thoracolumbar compression fractures, the limited middle and posterior column osteotomy via transvertebral space approach has a satisfactory effectiveness. Compared with PSO, it can reduce surgical trauma on the basis of achieving the same degree of deformity correction.

Abstract
OBJECTIVE Lateral lumbar corpectomy with interbody fusion has been well described via a transpsoas approach in the lateral position, as has lumbar interbody fusion with posterior fixation in the prone position. However, no previous report has described the use of both an open posterior approach and a lateral transpsoas approach simultaneously in the prone position. Here, the authors describe their technique of performing transpsoas lumbar corpectomy in the prone position in order to have simultaneous posterior and lateral access for difficult clinical scenarios, and they report their early clinical experience. METHODS The surgical technique for simultaneous posterior and lateral transpsoas access to the lumbar spine was reviewed and described in detail. The cases of 2 patients who underwent simultaneous posterior and lateral access in the prone position for complex lumbar pathology were retrospectively reviewed. Clinical presentation, preoperative radiographs, postoperative course, and postoperative radiographs were reviewed. RESULTS The first patient presented after previous transforaminal lumbar interbody fusion that was complicated by significant subsidence of the intervertebral cage, vertebral body split fracture, rotational instability, and resulting spinal stenosis. A simultaneous posterior and lateral transpsoas approach in the prone position allowed for removal of the previous cage, lumbar corpectomy, and rigid posterior fixation with direct decompression. The second patient had a significant pathologic burst fracture secondary to a plasmacytoma with retropulsion, resulting in vertebra plana and significant canal stenosis. Simultaneous approaches allowed for complete resection of the plasmacytoma, restoration of lumbar alignment, rigid fixation, and direct posterior decompression. There were no short-term complications, and both patients had resolution of their preoperative symptoms. CONCLUSIONS Simultaneous posterior and lateral transpsoas access to the lumbar spine in the prone position is a previously unreported technique that allows a safe surgical approach to difficult clinical scenarios.

Abstract
BACKGROUND CONTEXT Thoracic costotransversectomies (TCT) are amongst the most invasive spine procedures performed. Of greatest concern to the patient and surgeon is the risk of iatrogenic neurologic injury associated with these procedures. Most available studies limit their assessment of neurologic function to nonspecific scales such as the broader ASIA scoring system of A to E and have not comprehensively described the rates of iatrogenic injury following these procedures by looking more precisely with ASIA motor scoring (0-100) which allows for more in-depth analysis. PURPOSE The purpose of this study is to investigate the rates and degree of iatrogenic neurologic decline following TCT and subsequent rates and degree of motor recovery. STUDY DESIGN/SETTING Retrospective medical record review at a single institution. PATIENT SAMPLE Around 116 consecutive patients undergoing TCT operations. OUTCOME MEASURES Neurological changes from preprocedure to final follow-up assessed by lower extremity motor score. METHODS A retrospective chart review of patients undergoing TCT between May 2008 and April 2018 was carried out. Clinical, surgical, and intraoperative neuromonitoring data were collected. Patients who demonstrated an initial postoperative decline in lower extremity motor scores (LEMS) were followed through their final follow up to assess recovery. RESULTS Around 116 patients underwent TCT between T2 and T12 between May 2008 and April 2018. Seven (6.0%) patients demonstrated an immediate postoperative decline as defined by a drop of more than 4 points (mean 15.1; range 5-50) in motor score. All patients who demonstrated an initial postoperative motor score decline returned to within 4 LEMS points of their preoperative LEMS by final follow up. IOMN changes were noted only in half of all monitored patients who were noted to have a decline. CONCLUSIONS In our series, 6.0% of patients undergoing TCT experienced an initial decline in motor score with 94.0% demonstrating an unchanged or improved examination compared to preoperative exam. In our series, all patients who exhibited a decline recovered to within 4 points of the preoperative motor score within the first year postoperatively.

Abstract
BACKGROUND There is some controversy about which is the best approach, decompression technique and number of fixed levels in the surgical treatment for burst thoracolumbar fractures. Without a neurological injury, correcting thoracolumbar kyphosis and preventing mechanical failure should be the main concerns. The two-segment short fusion with screws at fractured vertebra by posterior approach was performed in 64 patients. Although a significant increase of postoperative kyphosis was observed, there were not clinical consequences, nor was there reintervention for mechanical failure. METHODS Patients with unstable T11-L2 burst fractures and a two-level fusion including screws at the injured vertebra between 2000 and 2015 were included in the study. Demographic, clinical, and radiological variables were analyzed. Thoracolumbar, segmental, and vertebral kyphosis and anterior and posterior vertebral height were measured preoperatively, postoperatively, at one-year, and at the end of follow-up in the radiological study. The statistical analysis consisted of a descriptive analysis, and we used the t test to compare the preoperative, postoperative, one-year, and end-of-follow-up radiographs to observe a thoracolumbar T10-L2 kyphosis increase. Significance level was established at P < .05. RESULTS Fifty-four patients were included. A statistically significant increase of vertebral, segmental, and thoracolumbar kyphosis (P < .05) was observed during follow-up, without clinical consequences. CONCLUSIONS Two-segment fusion is an effective technique and allows initial deformity kyphotic correction after thoracolumbar burst fracture. The thoracolumbar kyphosis increased during the follow-up, without pain, disability, or mechanical failure. LEVEL OF EVIDENCE 2a.

Abstract
OBJECTIVE Controversy remains regarding the optimal methods for resection of the vertebral body, reconstruction of the anterior column, and decompression of the spinal cord in patients who have severe vertebral body destruction of the thoracic or lumbar spine with associated neurologic impairment. We report an alternative technique for primary treatment and salvage involving single-stage corpectomy followed by reconstruction of the anterior column using double small mesh cages via the posterior-only approach. METHODS Plain radiographs and computed tomography scans, taken at different intervals, were used to measure local kyphosis, segmental height, and fusion grade. Pain was evaluated using the visual analog scale (VAS), and neurologic symptoms were classified according to Frankel grade. RESULTS The mean kyphotic deformity improved by 14.47 ± 9.06 degrees (P < 0.001), and the mean segmental height improved by 7.17 mm ± 6.11 mm (P < 0.001) after surgery. Fusion was achieved at 84% of patients, within a median interval of 12 months. Kyphotic recurrence was observed in 2 patients (11%), segmental height loss occurred in 1 patient (5%), and both kyphotic recurrence and segmental height loss occurred in 1 patient (5%). None of the patients reported worsening pain or neurologic symptoms after surgery, and there were no surgery-related complications such as neural injury, cerebrospinal fluid leakage, cage dislocation, surgical site infection, or cardiopulmonary complications. CONCLUSIONS Single-stage corpectomy followed by reconstruction of the anterior column using double small mesh cages via the posterior-only approach is a reliable and less invasive single-stage treatment and salvage option in selected cases.

Abstract
PURPOSE For anterior spine column reconstruction after corpectomy, expandable cages offer solid anterior support and allow correction of deformity, providing excellent primary stability. To provide a larger body of clinical observations concerning the effectiveness of the approach, this retrospective study examines patients treated by corpectomy and reconstruction with an expandable cage for different pathologies. METHODS Across 5 years, 39 patients underwent vertebral reconstruction with expandable cages after single (n = 34), double (n = 4), or triple (n = 1) corpectomy. Pathologies were tumors (n = 21), fractures, or deformities in traumatic injuries (n = 14), degenerative pathology (n = 2), and infection (n = 2). Levels were cervical (n = 10), thoracic (n = 14), and lumbar (n = 15). All patients were evaluated clinically and radiographically. RESULTS There were no cases of neurologic deterioration. Nurick grade showed significant improvement at 3 months postoperative versus preoperative (p < 0.01). Visual analog scale significantly improved preoperatively versus 3 and 12 months postoperatively (both p = 0). Regional angulation was significantly corrected, from preoperative to 3 and 12 months postoperative, at cervical, thoracic, and lumbar levels. We achieved reconstruction of the normal local anatomy with full recovery of the height of the vertebral body. Six patients (15.4%) had complications and two (5.1%) underwent revision surgery. CONCLUSIONS In our experience, expandable cages confer stable anterior support, providing significant improvement of the segmental kyphosis angle and restoration of the original somatic height. Our clinical results are favorable, and the low rate of complications and revision accentuates the expandable cage as a valuable tool to replace the vertebral body in diverse pathologies and different spine levels.

Abstract
During the past 2 decades, the number of spinal surgeries performed annually has been steadily increasing, and these procedures are being accompanied by a growing number of postoperative imaging studies to interpret. CT is accurate for identifying the location and integrity of implants, assessing the success of decompression and intervertebral arthrodesis procedures, and detecting and characterizing related complications. Although postoperative spinal CT is often limited owing to artifacts caused by metallic implants, parameter optimization and advanced metal artifact reduction techniques, including iterative reconstruction and monoenergetic extrapolation methods, can be used to reduce metal artifact severity and improve image quality substantially. Commonly used and recently available spinal implants and prostheses include screws and wires, static and extendable rods, bone grafts and biologic materials, interbody cages, and intervertebral disk prostheses. CT assessment and the spectrum of complications that can occur after spinal surgery and intervertebral arthroplasty include those related to the position and integrity of implants and prostheses, adjacent segment degeneration, collections, fistulas, pseudomeningoceles, cerebrospinal fluid leaks, and surgical site infections. Knowledge of the numerous spinal surgery techniques and devices aids in differentiating expected postoperative findings from complications. The various types of spinal surgery instrumentation and commonly used spinal implants are reviewed. The authors also describe and illustrate normal postoperative spine findings, signs of successful surgery, and the broad spectrum of postoperative complications that can aid radiologists in generating reports that address issues that the surgeon needs to know for optimal patient management.©RSNA, 2019.

Abstract
Infections of the lumbar spine can have serious sequelae, including neurological deficits, paralysis, and death. Prolonged infection can result in fracture of the vertebrae, local abscesses, and infiltration and compression of local vascular structures. In cases with significant instability or neurological compromise, a common treatment approach is vertebral corpectomy with interbody cage followed by long-term antibiotics. The following case describes a patient with a three-month history of progressively worsening lower back pain, lower extremity radiculopathy, and bilateral lower extremity edema, in the setting of a nontraumatic three-column fracture dislocation of L5 with grade 4 retrolisthesis of L4 on L5. A posterior-only corpectomy with placement of an expandable cage, to be followed by pedicle screw placement from L3-S1/ilium, was performed. The procedure was successful, and the patient was discharged on postoperative day 5 without complication and with resolution of his edema. Histopathological analysis demonstrated acute and chronic inflammation, but extensive tests and cultures failed to identify a causative organism. This case highlights several interesting features, including a technically challenging and seldom-performed procedure, as well as the ability of lumbar spinal infections to present with leg edema due to involvement the inferior vena cava and iliac vessels. For patients with three-column fractures of L5 due to an inflammatory process or trauma, a single-stage posterior corpectomy with placement of an expandable cage may be considered as an appropriate treatment option.

Abstract
PURPOSE To evaluate a novel effective procedure utilizing three-column reconstruction via a posterior approach with a technique that utilizes an arthroscope to visualize the anterior surface of the dura during decompression. METHODS A Prospective Study. 80 Osteoporotic vertebral burst fracture patients with similar demographic data managed by three-column reconstruction through single posterior approach surgery: Pedicle screw fixation, Corpectomy, Arthroscope Assisted Transpedicular Decompression (AATD) and Fusion (Mesh Cage + Bone grafting). Preoperative and postoperative clinical parameters (Visual Analog Score VAS, swestry Disability Index ODI, neurlogy, radiological parameters and surgical variables were recorded analysed. RESULTS No significant differences in demographic data. Significant improvement was noted in VAS (pre-operative, 7.90 ±0.60; final follow-up 2.90 ± 0.54) and ODI (preoperative, 77.10 ± 6.96; final follow-up 21.30 ± 6.70). Neurological improvement was noted in 74 patients (Frankel grade E) while six patients remained non-ambulatory (Frankel grade C). Significant improvement was noted in local kyphosis angle (preoperative, 22.14 ± 2.60; postoperative, 10.40 ± 1.40) with a 10% loss of correction (2.5 ± 0.90) at final follow-up. Implant failure in two patients and proximal junctional failure in two patients managed with revision surgery. No iatrogenic dural or nerve injury. CONCLUSIONS Osteoporotic Burst fracture can be managed with single posterior surgery, three-column reconstruction with mesh cage. It provides a significant improvement in clinical, radiological and functional outcomes. The arthroscope can improve a surgeon's operative field and magnification thereby ensuring complete decompression without injuring the dura or spinal cord.

Abstract
Management of unstable thoracolumbar fractures remains controversial. Furthermore, when these are accompanied by related neurological injury, the choice of approach, decompression technique and timing of the intervention could have a neuroprotective effect. In terms of site, the lumbar spine represents only 1.2% of cases, yet fractures with severe instability and neurological injury call for attainment of the same goals, i.e., neurological stability and decompression. After suffering high-energy trauma as a result of an accidental fall, a young male patient presenting with unstable injury of the lumbar spine and neurological impairment compatible with incomplete cauda equina syndrome was treated with emergency stabilisation and decompression through single-stage posterior transpedicular approach. At one year of the intervention, the patient is making good progress, with absence of lumbar pain, isolated deficit in left ankle dorsiflexion with no need of orthosis or cane, adequate sphincter control and return to his previous activity. Patients who present with unstable injury of the lumbar spine and incomplete neurological involvement can benefit from emergency stabilisation and decompression treatment by posterior transpedicular approach, with improvement in neurological status and functional recovery.

Abstract
BACKGROUND Thoracolumbar pathology can result in compression of neural elements, instability, and deformity. Circumferential decompression with anterior column reconstruction is often required to restore biomechanical stability and minimize the risk of implant failure. OBJECTIVE To assess the safety and viability of wide-footprint rectangular cages for vertebral column resection (VCR). METHODS We performed VCR with wide-footprint rectangular endplate cages, which were designed for transthoracic or retroperitoneal approaches. We present our technique using a single-stage posterior approach. RESULTS A total of 45 patients underwent VCR with rectangular endplate cages. Mean age was 58 yr. Diagnoses included 23 tumors (51%), 14 infections (31%), and 8 deformities (18%). VCRs were performed in 10 upper thoracic, 17 middle thoracic, 14 lower thoracic, and 4 lumbar levels. Twenty-four cases involved a single level VCR (53%) with 18 two-level (40%) and 3 three-level (7%) VCRs. Average procedure duration was 264 min with mean estimated blood loss of 1900 ml. Neurological outcomes were stable in 27 cases (60%), improved in 16 (36%), and worse in 2 (4%). There were 7 medical and 7 surgical complications in 11 patients. There were significant decreases in postoperative thoracic kyphosis (47° vs 35°, P = .022) and regional kyphosis (34° vs 10°, P < .001). There were 2 cases of cage subsidence due to intraoperative endplate violation, neither of which progressed on CT scan at 14 and 35 mo. CONCLUSION Posterior VCR with rectangular footprint cages is safe and feasible. This provides improved biomechanical stability without the morbidity of a lateral transthoracic or retroperitoneal approach.

Abstract
Since the first vertebral body replacement operations over 50 years ago until now, there were developed numerous methods and implants. Vertebral body replacement after corpectomy nowadays is a standard procedure in spinal surgery. At the beginning mainly bone grafts were used. Due to continuous development, PMMA and titanium implants were developed. Nowadays various expandable and non-expandable implants are available. Numerous implants can still be justified. The question arises which methods and systems are on the market and which ones have proven themselves? This article describes and compares the advantages and disadvantages of each implant type.

Abstract
BACKGROUND Reconstruction of thoracolumbar structural stability is a formidable challenge for spine surgeons after vertebral body tumor resection. Various disadvantages of the currently used expandable or nonexpandable cages have limited their clinical applications. We sought to develop a novel prosthesis for clinical use and assess its preliminary clinical outcome in reconstruction of thoracolumbar structural stability after spinal tumor resection. METHODS Using data obtained from a retrospective analysis of the morphological characteristics of the thoracolumbar vertebrae and endplates in previously reported studies, we modified the nano-hydroxyapatite/polyamide-66 (n-HA/PA66) strut into a novel height-adjustable vertebral body. A retrospective study was performed of 7 patients who had undergone reconstruction of thoracolumbar structural stability with this novel prosthesis from August 2016 to January 2017. RESULTS A novel height-adjustable vertebral body (AHVB) composed of n-HA/PA66 with 2 separate components with a 163° contact surface at each end was manufactured. The height-adjustable range was 28-37 mm. No significant implant-related complications were observed in the process of operation. All patients experienced a significant reduction in pain, with the visual analog scale score decreasing from 7.9 to 4.0. Neurological improvement was assessed using the Frankel grading system after surgery. Postoperative radiographic and computed tomography/magnetic resonance imaging findings indicated that the operated segment was stable, the outcome of kyphosis correction was good, and no prosthesis subsidence or dislocation was observed. CONCLUSION This novel prosthesis has many advantages in the reconstruction of height, lordosis, and alignment after thoracolumbar spinal tumor resection and has a favorable prospect for clinical application.

Abstract
PURPOSE The posterior transpedicular approach (PTA) is a posterior approach that has the advantage of achieving circumferential arthrodesis by a single posterior-only approach. The purpose of this study was to analyze our experience with PTA in the management of pediatric traumatic thoracolumbar burst fractures (TTLBFs). METHODS Consecutive pediatric patients (age ≤18 years) with TTLBFs treated with PTA for 6 years were included in this retrospective study. Correction of kyphotic deformity and change in neurologic status were analyzed to assess outcome. The Cobb angle and American Spinal Injury Association (ASIA) grade were used for this purpose. RESULTS There were 6 male and 8 female patients. Five patients had complete injury (ASIA-A), and 9 had incomplete injury. The mean Thoracolumbar Injury Classification and Severity score was 6.71. The mean preoperative Cobb angle was 14.71° and improved to -3.35° postoperatively (mean kyphosis correction -18.05°). Two of the patients experienced iatrogenic nerve root injury. There was 1 postoperative mortality due to complications unrelated to the surgery. The mean Cobb angle was -0.07° at the 32.2-month follow-up visit. Six patients experienced cage subsidence, but none required revision surgery. Postoperatively, 11 (78.5%) patients showed neurologic improvement, and none experienced deterioration. The average ASIA score improved from 2.5 to 3.78. A fusion rate of 100% (n = 12) was observed at the last follow-up visit. CONCLUSIONS The present study demonstrates that PTA is a feasible approach in selected pediatric patients with unstable traumatic thoracolumbar burst fractures, with results comparable with those in the adult population. This study demonstrates in detail the procedure, along with the neurologic and radiologic outcomes of this approach in the pediatric population.

Abstract
STUDY DESIGN A laboratory cadaveric study. OBJECTIVE We aimed to demonstrate the feasibility of a posterior oblique approach, sharing the same advantages as the transpsoas technique while minimizing the risk of lumbar plexus or psoas muscle injuries. SUMMARY OF BACKGROUND DATA The transpsoas approach for interbody fusion and corpectomy offers advantages over posterior and anterior approaches. However, possible risks include traumatization of the psoas muscle or lumbar plexus. METHODS All lumbar disk spaces and vertebral bodies were exposed by a posterior oblique approach from left and right on a human cadaveric specimen. The exposure obtained and a step-by-step documentation of the procedure is outlined in detail. RESULTS We were able to achieve wide exposure of all lumbar disk spaces and vertebral bodies above the L5/S1 disk space. Only the psoas muscle was retracted, and the lumbar plexus nerves were easily visualized and gently retracted. Sharp dissection was only required around the tip of the transverse processes. CONCLUSIONS A posterior oblique approach seems to be less invasive than the transpsoas approach. Exposure of the anterior column structures above the iliac crest is comparable. The oblique approach offers direct access to the lumbar plexus and the extraforaminal segments of the nerve roots.

Abstract
Posttraumatic deformities after vertebral fractures are challenging for orthopedic surgeons in the non-operative and operative field. Especially osteoporotic fractures may cause a hyperkyphosis resulting in segmental or global sagittal imbalance and chronic back pain. Different vertebral osteotomies are potent to restore sagittal profile but show a very high perioperative risk including neurological and soft tissue complications. In addition, some of these extensive operations require a two-step procedure including posterior and anterior approaches. Therefore, these established techniques may be contraindicated in elderly or multimorbide patients suffering from concomitant diseases. The authors describe the double transforaminal lumbar interbody fusion (TLIF) osteotomy (DTO) as an innovative one-stage and low-invasive surgical technique to correct a fixed posttraumatic kyphosis in the thoracolumbar junction. The procedure includes posterior release (laminectomy, facettectomy, nucleotomy) combined with two expandable TLIF implants (sandwich technique) and posterior instrumentation and is illustrated by a case of a multimorbide 78-year old female.

Abstract
STUDY DESIGN This was a retrospective study. OBJECTIVE To compare the radiographic and clinical results of anterior support with nonexpandable cage with those of expandable cage. SUMMARY OF BACKGROUND DATA The goals of surgical treatment in patients with thoracolumbar angular kyphosis are to improve the neurological deficit through neural decompression, to restore the normal alignment by correction of deformity, and to stabilize the spinal column by arthrodesis. Mesh cages have been traditionally used for reconstruction after corpectomy. However, expandable cages are gaining popularity due to some advantages over mesh cages, structural autograft or allograft, and poly-ether-ether-ketone/carbon fiber. MATERIALS AND METHODS We performed a retrospective study in a consecutive series of 42 subjects with a male-to-female ratio of 15:27, a mean age of 65.3±10.9 years, and a mean follow-up period of 36.4±7.1 months, who underwent posterior vertebral column resection at our medical institutions between 2006 and 2011. They consist of 32 patients with posttraumatic kyphosis with a mean kyphotic angle of 33.1 degrees (range, 12.2-58.1 degrees) and 10 patients with tuberculous kyphosis with a mean kyphotic angle of 53.9 degrees (range, 22.6-126.0 degrees). The mean follow-up period was 36.4 months (range, 28-54 mo). We compared the clinical outcomes between the 2 groups based on radiographic findings, neurological status, and complications. Intervertebral heights and kyphosis at the level of vertebral column resection were used to measure the radiographic outcomes. Neurological outcome was evaluated using the modified Frankel grading system. RESULTS Postoperatively, the mean kyphosis angle was 3.0±10.8 and 6.7±7.2 degrees (P=0.094). At a final follow-up, these values were 4.7±10.1 and 12.3±18.9 degrees in the corresponding order (P=0.099). There were 19 (80.0%) and 21 (86.4%) patients with solid arthrodesis of grade 1. On modified Frankel grading system, all the patients but one achieved improvement. But there was no significant difference in the grade between the 2 groups (P>0.05). Also in our series, there were 12 patients with cage subsidence and 6 with screw loosening. CONCLUSIONS Nonexpandable cage and expandable cage are viable options for anterior support; both cages allow for correction of kyphosis with good fusion rate with similar neurological outcomes. Expandable cage is effective for the anterior support of posterior vertebral column resection.

Abstract
STUDY DESIGN Retrospective clinical and radiographic study. OBJECTIVE To examine the efficacy and safety of vertebrectomy and expandable cage placement by a single-stage posterior approach for unstable mid and lower lumbar burst fractures (below the L3). SUMMARY OF BACKGROUND DATA Patients with unstable mid and lower lumbar burst fractures require surgical treatment to relieve pain, address paralysis, and stabilize the spine to prevent further segmental deformity. However, controversy remains regarding the optimal surgical treatment. MATERIALS AND METHODS Eleven patients underwent single-stage posterior-only vertebral column resection and vertebral body reconstruction using an expandable cage. Neurological status was classified using the American Spinal Injury Association (ASIA) Impairment Scale, whereas functional outcome was analyzed using a visual analog scale for back pain. Segmental Cobb angles were measured above and below the fractured vertebral body preoperatively, immediate postoperatively, and at the last follow-up. RESULTS The preoperative neurological status was ASIA grade E in 2 patients, grade D in 5 patients, grade C in 2 patients, and grade B in 2 patients. Postoperatively, neurological stability was demonstrated in 3 patients (27%), and 8 (73%) showed improvement in the ASIA grade. The mean preoperative visual analog scale score was 8.3, which decreased to 4.5 postoperatively, and to 1.8 at the final follow-up. The mean preoperative segmental lordotic angle was 9.2 degrees, which increased to 16.9 degrees postoperatively, and decreased to 15.1 degrees at the last follow-up. The mean operating time was 208.8 minutes, and the mean blood loss was 1006.3 mL. Regarding surgical complications, 1 patient experienced a dural tear and 1 patient demonstrated cage subsidence. CONCLUSIONS The results of this small series suggest the feasibility, efficacy, and safety of this surgical option for unstable mid and lower lumbar burst fractures. This technique from a single posterior approach offers several advantages over traditional anterior or combined approaches using strut graft or nonexpandable implants.

Abstract
Spinal trauma is a devastating event with a high morbidity and mortality. The rationale of imaging is to diagnose the traumatic abnormalities and characterize the type of injury, to estimate the severity of the lesions, to evaluate the potential spinal instability. In case of spinal instability, the goals of operative treatment are decompression of the spinal cord canal and stabilization of the disrupted vertebral column. Particularly, diagnostic imaging, mainly by CT and MR, has a main role in the post-treatment evaluation. The neuroradiological evaluation of the postoperative spine requires a general knowledge of the surgical approach to each spinal region and of the normal temporal evolution of expected postoperative changes. The neuroradiologist should evaluate the devices implanted, their related complications and promptly alert the surgeon of acute complications, mainly vascular and infective. During the follow-up, it is mandatory to know and search chronic complications as pseudomeningocele, accelerated degenerative disease, arachnoiditis, peridural fibrosis. Knowledge of specific complications relating to each surgical approach will assist the neuroradiologist in interpretation of postoperative images.

Direct Midline Posterior Corpectomy and Fusion of a Lumbar Burst Fracture with Retrospondyloptosis. World Neurosurg 2017; 99:809.e11-809.e14.

Abstract
BACKGROUND Traumatic burst fractures of the lumbar spine can result in significant neurologic injury and mechanical instability. The ideal surgical approach for the treatment of unstable lumbar spine burst fractures remains debatable. CASE DESCRIPTION A 37-year-old man presented with severe neurologic injury including loss of motor function below the level of the iliopsoas muscles bilaterally, saddle anesthesia, and absent rectal tone, after a fall from 18.28 m (60 ft). Computed tomography showed an L4 vertebral body comminuted burst fracture with complete posterior translation of L4 over L5. The patient was taken to the operating room for an L4 corpectomy and L2-S1 posterior fusion. The L4 vertebral body was visualized posterior to the posterior elements of L5 and resected in a piecemeal fashion. Because the thecal sac had been completely transected, a visible path down the L3-L4 and L4-L5 disk spaces was apparent, allowing direct posterior discectomies at these levels and completion of the L4 segment resection. The use of a direct posterior approach resulted in minimal blood loss, correction of sagittal alignment, and satisfactory outcomes comparable with the standard posterior transpedicular approach. Construct stability and solid bony fusion have been maintained for 4 years postoperatively. CONCLUSIONS The use of a direct midline posterior corpectomy approach may be considered for patients with lumbar burst fractures, high-grade neurologic injury, and transection of the thecal sac.

Abstract
OBJECTIVE This study aims to improve the understanding of the anatomic variations along the thoracic and lumbar spine encountered during an all-posterior vertebrectomy, and reconstruction procedure. This information will help improve our understanding of human spine anatomy and will allow better planning for a vertebral body replacement (VBR) through either a transpedicular or costotransversectomy approach. SUMMARY OF BACKGROUND DATA The major challenge to a total posterior approach vertebrectomy and VBR in the thoracolumbar spine lies in the preservation of important neural structures. METHODS This was a retrospective analysis. Hundred normal magnetic resonance imaging (MRI) spinal studies (T1-L5) on sagittal T2-weighted MRI images were studied to quantify: (1) mid-sagittal vertebral body (VB) dimensions (anterior, midline, and posterior VB height), (2) midline VB and associated intervertebral discs height, (3) mean distance between adjacent spinal nerve roots (DNN) and mean distance between the inferior endplate of the superior vertebrae to its respective spinal nerve root (DNE), and (4) posterior approach expansion ratio (PAER). RESULTS (1) The mean anterior VB height gradually increased craniocaudally from T1 to L5. The mean midline and posterior VB height showed a similar pattern up to L2. Mean posterior VB height was larger than the mean anterior VB height from T1 to L2, consistent with anterior wedging, and then measured less than the mean anterior VB height, indicating posterior wedging. (2) Midline VB and intervertebral disc height gradually increased from T1 to L4. (3) DNN and DNE were similar, whereby they gradually increased from T1 to L3. (5) Mean PAER varied between 1.69 (T12) and 2.27 (L5) depending on anatomic level. CONCLUSIONS The dimensions of the thoracic and lumbar vertebrae and discs vary greatly. Thus, any attempt at carrying out a VBR from a posterior approach should take into account the specifications at each spinal level.

Abstract
STUDY DESIGN In vitro cadaver biomechanics study. OBJECTIVE The goal of this study is to compare the in situ fatigue life of expandable versus fixed interbody cage designs. SUMMARY OF BACKGROUND DATA Expandable cages are becoming more popular, in large part, due to their versatility; however, subsidence and catastrophic failure remain a concern. This in vitro analysis investigates the fatigue life of expandable and fixed interbody cages in a single level human cadaver corpectomy model by evaluating modes of subsidence of expandable and fixed cages as well as change in stiffness of the constructs with cyclic loading. METHODS Nineteen specimens from 10 human thoracolumbar spines (T10-L2, L3-L5) were biomechanically evaluated after a single level corpectomy that was reconstructed with an expandable or fixed cage and anterior dual rod instrumentation. All specimens underwent 98 K cycles to simulate 3 months of postoperative weight bearing. In addition, a third group with hyperlordotic cages was used to simulate catastrophic failure that is observed in clinical practice. RESULTS Three fixed and 2 expandable cages withstood the cyclic loading despite perfect sagittal and coronal plane fitting of the endcaps. The majority of the constructs settled in after initial subsidence. The catastrophic failures that were observed in clinical practice could not be reproduced with hyperlordotic cages. However, all cages in this group subsided, and 60% resulted in endplate fractures during deployment of the cage. CONCLUSIONS Despite greater surface contact area, expandable cages have a trend for higher subsidence rates when compared with fixed cages. When there is edge loading as in the hyperlordotic cage scenario, there is a higher risk of subsidence and intraoperative fracture during deployment of expandable cages.

Abstract
Spinal involvement occurs frequently in cases of eosinophilic granuloma (EG), but surgical treatment is limited primarily to those with spinal instability. Involvement of the cervical spine is rare, but primarily occurs in the vertebral bodies, and is normally amenable to anterior corpectomy and spinal reconstruction. The authors describe a 27-year-old man with pathologically proven EG who presented with complete destruction of the C-1 lateral mass requiring spinal stabilization. A titanium expandable cage was used to reconstruct the weight-bearing column from the occipital condyle to the superior articular surface of C-2 from a posterior approach, with preservation of the traversing vertebral artery. To the authors' knowledge, this is the first reported instance of reconstruction of the C-1 lateral mass using an expandable metal cage, which facilitated preservation of the vertebral artery.

Abstract
OBJECTIVE Currently, anterior, posterior, or combined approaches are used in various spinal disorders; however, a single-stage posterolateral transpedicular approach with 360° stabilization and vertebrectomy provides better results for spinal tumors. METHODS We evaluated the age, sex distribution, presenting symptoms, neurologic examination findings according to the pre- and postoperative Frankel classification, pre- and postoperative VAS pain scores, preoperatively administered medical therapies, pre- and postoperative corset use, level of the lesion, levels of previous surgical interventions, root ligation (if performed), results of the primary disease, hospitalization duration (after the operation), postoperative complications (if any), postoperative follow-up duration, and postoperative survival duration of 22 patients. RESULTS We observed that primary bone tumors were localized in the lumbar (75%) and thoracic regions (25%) and that metastatic tumors were localized in the thoracic (77.78%) and lumbar regions (22.22%). The VAS and Frankel scores of the 22 patients who were included in the study revealed that this surgical treatment modality was associated with statistically significant improvements in test scores (P < 0.001). No ribcage dislocation was observed. In 1 patient (4.54%), a neurologic deficit developed. Two patients (9.09%) required revision because of screw malposition. CONCLUSIONS In spinal tumors, 360° fusion performed via a posterolateral approach is a less risky, relatively safe, and less invasive method. This method, which reduces the risks of anesthesia and internal problems and decreases cost, is an essential technique for decreasing hospitalization duration, improving pain levels, and achieving faster mobilization and faster initiation of radiotherapy and chemotherapy.

Anterior approach with expandable cage implantation in management of unstable thoracolumbar fractures: Results of a series of 93 patients. Neurochirurgie 2016; 62:78-85. [PMID: 27131636 DOI: 10.1016/j.neuchi.2016.01.001] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2015] [Revised: 01/24/2016] [Accepted: 01/29/2016] [Indexed: 11/23/2022]
Abstract
INTRODUCTION Anterior approach indications in unstable thoracolumbar fractures (UTLF) are debated. The aim of this study was to evaluate the results of anterior fixation and expandable prosthetic vertebral body cage (EPVBC) implantation alone or combined with a posterior approach in the management of UTLF. MATERIALS AND METHODS Ninety-three patients underwent anterior fixation with implantation of an EPVBC for UTLF from T7 to L5. Long-term kyphosis and vertebral height loss reduction, functional outcomes including visual analogical scale and Oswestry disability index were evaluated. RESULTS Anterior fixation led to a significant increase of vertebral body height with a gain of 13% after a previous posterior approach, 38% after a single anterior approach and 65% after combined posterior and anterior approaches (P=0.0001). However, anterior fixation did not significantly enhance the vertebral regional kyphosis angle (P=0.08), except in cases of single anterior approach for thoracic fractures (P=0.03). No significant difference was found between early, 3 months and 1 year postoperative vertebral regional kyphosis angle and vertebral body height (P=0.6). Complete fusion was routinely observed at 1 year postoperatively. rhBMP2 implantation in selected cases appears to be a safe and reliable strategy. No infections or surgical revisions were observed after the anterior approach. CONCLUSION Anterior approach and EPVBC implantation, in UTLF, is a safe and effective procedure, providing long-term vertebral body height and kyphosis correction. Adverse effects of anterior approach remain acceptable. Single anterior fixation is a reliable surgical alternative in thoracic fractures without posterior spine segment injury or spinal cord compression. These results prompted us to extend anterior approach indications in oncology and infectious diseases.

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

Abstract
Study Design Case report. Objective The purpose of this report is to discuss the surgical management of lumbar vertebral osteomyelitis with a spinal epidural abscess (SEA) and present a single-stage, posterior-only circumferential decompression and reconstruction with instrumentation using an expandable titanium cage and without segmental nerve root sacrifice as an option in the treatment of this disease process. Methods We report a 42-year-old man who presented with 3 days of low back pain and chills who rapidly decompensated with severe sepsis following admission. Magnetic resonance imaging of his lumbosacral spine revealed intramuscular abscesses of the left paraspinal musculature and iliopsoas with SEA and L4 vertebral body involvement. The patient failed maximal medical treatment, which necessitated surgical treatment as a last resort for infectious source control. He underwent a previously undescribed procedure in the setting of SEA: a single-stage, posterior-only approach for circumferential decompression and reconstruction of the L4 vertebral body with posterior segmental instrumented fixation. Results After the surgery, the patient's condition gradually improved; however, he suffered a wound dehiscence necessitating a surgical exploration and deep wound debridement. Six months after the surgery, the patient underwent a revision surgery for adjacent-level pseudarthrosis. At 1-year follow-up, the patient was pain-free and off narcotic pain medication and had returned to full activity. Conclusion This patient is the first reported case of lumbar osteomyelitis with SEA treated surgically with a single-stage, posterior-only circumferential decompression and reconstruction with posterior instrumentation. Although this approach is more technically challenging, it presents another viable option for the treatment of lumbar vertebral osteomyelitis that may reduce the morbidity associated with an anterior approach.

Single posterior approach for circumferential decompression and anterior reconstruction using cervical trabecular metal mesh cage in patients with metastatic spinal tumour. World J Surg Oncol 2015; 13:256. [PMID: 26306896 PMCID: PMC4549874 DOI: 10.1186/s12957-015-0685-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2015] [Accepted: 08/17/2015] [Indexed: 12/03/2022] Open
Abstract
Background The goal of surgical management of metastatic spinal tumours is to remove the tumour mass, restore spinal stability and alignment, and provide a better quality of life. A single posterior transpedicular approach, with circumferential decompression, for anterior reconstruction has been advocated to reduce the risk of complication and morbidity associated with a combined anterior-posterior approach. The purpose of our study was to evaluate the clinical outcomes of patients who underwent a single posterior approach for anterior reconstruction at our institution to determine the feasibility and effectiveness of the approach, including the use of a cervical trabecular metal (TM) mesh cage as a vertebral body replacer. As a secondary aim, we evaluated the effect of accumulated experience with the surgical approach on clinical outcomes. Methods Twenty consecutive cases of single posterior approach were identified from a retrospective review of spinal surgeries performed at our institution between January 2009 and December 2012. Information on the following clinical outcomes was retrieved from the medical charts for analysis: visual analogue pain score (VAS); neurological status, classified on the Frankel scale; vertebral body reconstruction; spinal alignment, using Cobb’s angle; operative time; volume of blood loss; complications; and the modified Brodsky criteria score, which was used to classify functional recovery as excellent, good, fair, or poor. Results Pre- to post-surgical evaluation of outcomes demonstrated a significant decrease in pain (p < 0.001), improved spinal alignment, with a mean correction angle of 12° (range, 3°–29°), and higher Frankel score (p < 0.001). No severe complications were identified, including deep surgical infection or neurologic deterioration. Eighteen patients achieved good to excellent outcomes, based on the modified Brodsky criteria (p < 0.001), with two patients dying within 9 and 11 months of their surgery. Accumulated surgical experience reduced operative time and intraoperative blood loss (p ≤ 0.007). Conclusions A single posterior approach provided good to excellent clinical and functional outcomes. Based on this evidence, we propose that a posterior approach provides a feasible alternative to the combined posterior-anterior approach for managing patients with metastatic spinal tumours.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE To give some insight in balancing cost and effectiveness of 3 different techniques of corpectomy in destructive thoracolumbar spine disease. SUMMARY OF BACKGROUND DATA Although there are several accepted methods of surgical treatment of single-level corpectomy in destructive metastatic thoracolumbar spine disease, the choice depends on the surgeon's preference. The techniques may vary in perioperative morbidity and short- and long-term outcome, but no study so far has analyzed their cost-effectiveness. METHODS Seventy-five consecutive patients, mean age of 57 years (range: 39-72 yr) with single-level destructive thoracolumbar lesion underwent surgical treatment with 3 different techniques in 2 centers from 2009 to 2013. The 3 groups were (1) mini open transpedicular corpectomy, (2) conventional open transpedicular corpectomy, and (3) the combined posterior-anterior approach. The data were collected prospectively according to our protocol and subsequently analyzed. The clinical outcome was assessed comparing visual analogue scale score of back pain and the short form 12 (SF-12) questionnaire both pre- and postoperatively. The cost analysis was done calculating the operative time, hospital stay, and the implant cost. RESULTS The mean follow-up period was 25 months (range: 24-30 mo). The clinical outcome in terms of visual analogue scale score of thoracolumbar pain and SF-12 physical and mental score improvement (P < 0.005) were comparable with all 3 techniques. The radiological outcome was comparable with current available data. As the intensive care unit stay (average: 7 d) and the hospital stay were longer (average: 15 d) with combined posterior-anterior approach, the total cost was maximum (average: €20,952) with this group. CONCLUSION Using the posterior approach only was the most cost-effective technique, but the mini open was comparable with the conventional open transpedicular approach. LEVEL OF EVIDENCE 3.
