Abstract
The conventional treatment for the resection of cervical spinal tumors comprises anterior, posterior, and combined surgical approaches. However, these approaches have certain limitations when tumors invade the vertebrae, vertebral artery, or spinal nerves. Herein, we report an interesting case where a 45-year-old patient was admitted for neck pain. An invasive cervical spinal tumor was discovered and approached in two stages: stage 1 was open biopsy with posterior instrumentation, which was followed by stage 2 with an anterolateral approach for definitive surgical resection. A series of preoperative tests including angiography as well as a balloon occlusion test of the vertebral artery facilitated stage 2 surgical planning for gross total resection of the tumor while minimizing surgical complications.

Abstract
PURPOSE Axial malignant bone tumours are rare in children and adolescents, and their prognosis is still relatively poor due to non-specific symptoms, such as back or groin pain, which may result in late hospital presentation. Therefore, it is very important to raise awareness regarding this pathology. METHODS We performed a narrative review, including scientific publications published in English. We searched Medline and Google Scholar databases for information on the incidence and prognosis of axial malignant bone tumours in children and adolescents (< 18 years). Outcomes of different surgical management strategies and reconstruction options were assessed. RESULTS The incidence of primary malignant bone tumours before the age of 18 years is approximately five per one million population; around 25% of these tumours are located in the axial skeleton. With a five-year survival rate of 50%, tumours in an axial location (chest cage, spine, pelvis) are associated with a poorer prognosis than tumours in more peripheral locations. En bloc excision with clear margins has been shown to improve local control and overall survival, even though obtaining adequate surgical margins is difficult due to the close location of large neurovascular structures and other major organs. Spinal reconstruction options include instrumented fusion with allograft or expandable cage. Pelvic reconstruction is needed in internal hemipelvectomy, and the options include biological, endoprosthetic reconstructions, hip transposition, arthrodesis or creation of pseudoarthrosis and lumbopelvic instrumentation. CONCLUSION Early diagnosis, a timely adequate multidisciplinary management, appropriate en bloc excision, and reconstruction improve survival and quality of life in these patients.

Abstract
Primary Ewing sarcoma in the spine is very rare, and the treatment for it is multidisciplinary. There is no consensus regarding the optimal method of local control; however, en bloc resection is associated with an improvement in survival rates. The authors report a case of a 5-year-old girl who initially presented low back pain, and was diagnosed with Ewing sarcoma after being submitted to imaging studies by radiography, magnetic resonance and bone biopsy. A spondylectomy was performed in accordance with the Euro Ewing protocol. At the three-year follow-up, the patient had no restrictions regarding her daily activities, and there has been no evidence of recurrence to date.

Abstract
Objective: To demonstrate a novel technique for multilevel en bloc post-vertebrectomy reconstruction. Methods: A novel technique for en bloc multiple post-vertebrectomy reconstruction was used in a patient presenting for curative resection of Ewing's Sarcoma at the oncology center of a public university hospital. Results: The procedure described was feasible for en bloc resection of the four vertebrae. The reconstruction was acceptable and satisfactory in terms of mechanical stability and was without any neurological sequelae in the patient. Conclusion: The use of an allograft with a locked intramedullary nail was an adequate solution for reconstructing the anterior and medial spines after multilevel vertebrectomy. In addition, the association of four intramedullary nails provided stability to the reconstruction. Immediate benefits of the technique compared to other commonly used techniques were shorter hospitalization times and reduced surgical morbidity. Level of Evidence V, Clinical study of a new surgical technique and a literature review.

Abstract
Primary vertebral leiomyosarcoma in thoracic spine is extremely rare. Metastatic origin must be excluded. Wide surgical excision can result in local tumor control and long-term survival.
Introduction To describe an unusual primary vertebral leiomyosarcoma in thoracic spine. Presentation of case An isolated lesion of the T11 vertebra in a 62-year-old woman with no neurologic deficit is reported. Imaging findings indicated a nonspecific high-grade malignant lesion. TC-guided biopsy failed thus open incisional biopsy was needed. A diagnosis of low-intermediate mesenchymal sarcoma was made. A total en bloc spondylectomy of T11 was performed with three-column reconstruction. The histology and immunostaining showed the appearance of leiomyosarcoma. After diagnosis, post-operative radiation therapy was performed. Metastatic lesion was ruled out by CT scans of the chest, abdomen and pelvis, in addition to total body radionuclide scanning and 18-F-FDG-PET. After five years of follow-up, no signs of local recurrence, metastasis or distant lesions suggesting a primary lesion were observed. Discussion Vertebral primary leiomyosarcoma is exceedingly rare. Primary vertebral leiomyosarcoma diagnosis must be performed when the metastatic origin is excluded. For the treatment of primary tumors, total en bloc spondylectomy (TES) is the technique of choice to achieve marginal or wide tumor resection, decrease the risk of local recurrence and remote lesions and increase survival. Conclusions A well-planned pre-operative study and a wide surgical excision can result in local tumor control and long-term survival. This case presents the longest disease-free survival period of a primary leiomyosarcoma in spinal location after total en bloc spondylectomy.

Abstract
A 47-year-old woman presented with symptoms of low back pain and weakness in bilateral lower limbs. MRI of the spine revealed a mass arising from T11 vertebra involving neural foramina at bilateral T11-12 and right T10-11 levels with extension to the right paravertebral region. Suspecting a nerve sheath tumour, she underwent posterior spinal decompression, stabilisation and debulking, following which her neurological symptoms resolved. Histopathological and immunohistochemical evaluation revealed a leiomyosarcoma. A month later she developed sudden paraparesis and MRI revealed an increase in size of the tumour with cord compression and displacement. She underwent a repeat spinal decompression and debulking procedure after which she received adjuvant radiotherapy via volumetric modulated arc therapy, to a total dose of 45 Gy in 25 fractions over 5 weeks. MRI performed 2 months later revealed complete response and she is disease free for the past 5 months.

Abstract
Primary osseous leiomyosarcoma of the spine is a very unusual condition, with only few cases being reported in the literature. In fact, this type of tumors arises from the smooth muscle cells and occurs usually in the uterus and the gastrointestinal tracts. If the spine should be involved, it occurs generally as a metastatic location. Location to the spine as a primary site is exceedingly rare. We present the case of a 37 years old female patient, with multiple spine levels involvement - to vertebral body and to posterior aspects of Vertebra, causing spinal cord compression syndrome. A secondary location to the skull was diagnosed one month later. Through a literature review, we analyze various aspects in the diagnosis and management of this rare entity.

Abstract
The present study aimed to analyze the indications, feasibility, safety and clinical effects of total spondylectomy and spine reconstruction through posterior or combined anterior-posterior approaches for thoracic lumbar and sacral vertebrae tumors. Between December 2009 and May 2012, 10 patients with thoracic lumbar and sacral vertebrae tumors were retrospectively analyzed. Different surgical indications and approaches were used according to the affected segments, the extent of lesion involvement and the specific pathology results. One-stage posterior or combined anterior-posterior total spondylectomy and reconstruction was used for the treatment of complicated thoracic lumbar and sacral vertebral malignant tumors and invasive benign tumors. The duration of surgery, levels of intraoperative blood loss and transfusions, and the clinical effects were observed. The average surgical duration was 6.8 h (range, 4.8-12 h), with an average blood loss level of 3,200 ml (range, 1,500-10,000 ml) and an average transfusion level of 2,500 ml. During the average 15 months (range, 3-29 months) follow up, two patients succumbed and one patient experienced tumor recurrence. Neither tumor reoccurrence nor metastasis was observed in all other patients. Personalized surgical indications and approaches according to the affected segments, the extent of lesion involvement and the specific pathology results would aid in the reduction of pain, the improvement of nerve function and the reduction of tumor recurrence.

Abstract
BACKGROUND Over the years, en bloc spondylectomy has proven its efficacy in controlling spinal tumors and improving survival rates. However, there are few reports of large series that critically evaluate the results of multilevel en bloc spondylectomies for spinal neoplasms. QUESTIONS/PURPOSES Using data from a large spine tumor center, we answered the following questions: (1) Does multilevel total en bloc spondylectomy result in acceptable function, survival rates, and local control in spinal neoplasms? (2) Is reconstruction after this procedure feasible? (3) What complications are associated with this procedure? (4) is it possible to achieve adequate surgical margins with this procedure? METHODS We retrospectively investigated 38 patients undergoing multilevel total en bloc spondylectomy by a single surgeon (AL) from 1994 to 2011. Indications for this procedure were primary spinal sarcomas, solitary metastases, and aggressive primary benign tumors involving multiple segments of the thoracic or lumbar spine. Patients had to be medically fit and have no visceral metastases. Analysis was by chart and radiographic review. Margin quality was classified into intralesional, marginal, and wide. Radiographs, MR images, and CT scans were studied for local recurrence. Graft healing and instrumentation failures at subsequent followup were assessed. Complications were divided into major or minor and further classified as intraoperative and early and late postoperative. We evaluated the oncologic status using cumulative disease-specific and metastases-free survival analysis. Minimum followup was 24 months (mean, 39 months; range, 24-124 months). RESULTS Of the 38 patients, 34 (89%) were alive and walking without support at final followup. Thirty-one (81%) had no evidence of disease. Two patients died postoperatively and another two died of systemic disease (without local recurrence). Only three patients (8%) had a local recurrence. There were 14 major complications and 22 minor complications in 25 patients (65%). Only one patient required revision of implants secondary to mechanical failure. Two cases of cage subsidence were noted but had no clinical significance. Wide margins were achieved in nine patients (23%), marginal in 25 (66%), and intralesional in four (11%). CONCLUSIONS In patients with multisegmental spinal tumors, oncologic resections were achieved by multilevel en bloc spondylectomy and led to an acceptable survival rate with reasonable local control. Multilevel en bloc surgery was associated with a high complication rate; however, most patients recovered from their complications. Although the surgical procedure is challenging, our encouraging mid-term results clearly favor and validate this technique. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
Since 1922 surgical approaches toward limb salvage in bone and soft tissue tumours have been documented. There is the famous "Umkippplastik" of Sauerbruch, the "Tikhoff-Linberg" inter-scapulo-thoracic resection or in 1943 a metallic tumour prosthesis for the hip joint in the United States (Moore, Bohlman). Since 1960 acrylic prostheses and metallic prosthesis with bone cement have been in use. Cement-free implants and the first modular ceramic prostheses were implanted in the 1970s in Vienna. At the same time successful chemotherapy in bone sarcomas was introduced by Gerald Rosen and Norman Jaffe. This was mainly the decade of custom-made prostheses. In the 1980s modular tumour prostheses with cone connection to be adopted to the needs of the patient were built intra-operatively. Since 1981 biannual international meetings (ISOLS) have pushed forward the field of bone tumour treatment to allow also tumour resection in wide borders for spine and pelvic tumours. New hope for resistant tumours could be monoclonal antibodies or even dendritic cell therapy.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE To report results of 4- and 5-level en bloc spondylectomy (EBS) in the treatment of malignant spinal tumors. SUMMARY OF BACKGROUND DATA EBS is widely used to avoid local recurrence in the treatment of spinal malignant tumors. Four- and 5-level EBS are aggressive procedures associated with complications and morbidity. METHODS We conducted a retrospective study of all patients treated with minimum 4-level EBS. Patient and surgical data were noted. Radiographs, magnetic resonance images, and computed tomographic scans were studied for local recurrence, graft, and instrumentation failures at subsequent follow-up. Type of excision was classified into intralesional, marginal, and wide margins. Complications were divided into major or minor and were further classified as intraoperative, early, and late postoperative. At the last follow-up, the patients were classified as alive with no evidence of local or systemic disease, alive with evidence of local or systemic disease or both, dead with evidence of local disease, or systemic disease or both, and dead without evidence of local and systemic disease. RESULTS Nine patients were identified who required a minimum 4-level en bloc resection. Five males and 4 females. Average age was 41.66 years (11-66). There were 8 primary malignant tumors: 3 chordomas, 3 osteosarcomas, 1 chondrosarcoma, 1 primary lung tumor and 1 metastatic alveolar soft part sarcoma. Six were operated with 4-level en bloc and 3 with 5 levels. The mean surgical time was 713 minutes and estimated blood loss was 4.5 L. Mean follow-up was 27.7 months (8-84). At the last follow-up, 6 patients were alive with no evidence of local or systemic disease, 1 alive with evidence of systemic disease, 1 dead with evidence of local disease, or systemic disease or both, and 1 DNLS. Only 1 (11%) patient had a local recurrence. Three patients with Frankel D had full neurological recovery. Histopathological assessment showed marginal margins in 7 patients and wide in 2. There were 9 major and 9 minor complications in 7 patients. Five of 7 patients (71%) with complications, had fully recovered from their complications at the last follow-up. CONCLUSION Multilevel EBS, can be offered to a patient to prevent local recurrence of disease. Even in experienced hands, the risks of intra- and postoperative complications are high (78%). However, most of the patients with complications, recovered completely (71%). Although the surgery itself may prove beneficial, patients should be well informed regarding the morbidity associated with it. LEVEL OF EVIDENCE 4.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE To assess critically if cross-links are necessary adjuvants in posterior spinal constructs. SUMMARY OF BACKGROUND DATA Although numerous biomechanical studies are available in the literature, there has been no clinical study that has evaluated the need for cross-links in clinical situations. METHODS The spinal constructs of patients of varied etiology who underwent surgery between July 2007 and July 2011 without the usage of cross-links were evaluated. The immediate postoperative erect radiographs were compared with the erect radiographs at the last follow-up by 2 independent observers (spine fellows not involved in the management of the patients) critically for any rotational instability using the Nash-Moe technique of assessment of vertebral rotation as well as for any "parallelogram effect." The intraobserver and interobserver reliability was analyzed. RESULTS There were 208 cases included in the study during the study period that satisfied the criteria. The total number of motion segments fused was 707 ranging from 1 to 15 involving various etiologies. The average follow-up was 15 months (12-36 mo). Barring one patient with a thoracolumbar fracture with rotational instability (AO [Arbeitsgemeinschaft für Osteosynthesefragen] type C) who had undergone a short-segment fixation, none of the cases demonstrated any rotational instability in the follow-up radiographs. Interestingly, the rotational instability (parallelogram effect) in that patient got corrected spontaneously once anterior reconstruction was performed. The intraobserver reliability was 100% and the interobserver reliability was 92.83%. This variability was in assessing the grade of vertebral rotation only; none of the levels had a change in rotation irrespective of variation in grade assessment in the final postoperative radiograph. CONCLUSION This study concludes that use of cross-links in clinical practice may be avoidable. The derivations from biomechanical studies do not translate into clinical advantages. Eliminating the usage of cross-links reduces the operative time as well as the overall total hospital costs (a single cross-link may cost anywhere between $1500 and $2000 and surgeons tend to use single or multiple cross-links). Additionally, prominence of implants, corrosion, infection, implant failure, and pseudarthrosis are the other complications attributed to cross-links in the literature that can be eliminated by preventing their incorporation in spinal constructs.

Restoration of biomechanically sufficient spinal stability. Functional preservation and/or regaining of adequate neurological function. INDICATIONS Primary malignant and benign, aggressive spinal tumors. Solitary metastatic tumors of biologically and prognostically favorable primary tumor (good prognostic scores). Extracompartmental, multisegmental vertebral tumor manifestations according to Tomita type 6. CONTRAINDICATIONS Diffuse spinal/vertebral tumor spread according to Tomita type 7 (disseminated spinal metastatic disease). Detection of distant metastases in the staging investigation. Biologically unfavorable tumor entities or primary systemic malignant tumors/diffuse disseminated malignoma (Tomita score < 4-5 points, Tokuhashi score < 12 points). SURGICAL TECHNIQUE Depending on tumor growth, sequential performance of the anterior and posterior approach for local tumor release and preparation/replacement of encased large vessels. Posterior approach via dorsomedial incision and exposure of the posterior vertebral elements. Costotransversectomy, resection of the facets, resection of paravertebral rib segments. Laminectomy in the tumor-free lamina segment, resection of the ligamentum flavum and paradural ligation of affected nerve roots, bilateral ligation of the segmental arteries. Digital extrapleural palpation and dissection to the anterior vertebral body parts. Insertion of S-shaped spatulas ventral to the anterior aspect of the spine, and dissection of the disc spaces and the posterior longitudinal ligament.

Abstract
STUDY DESIGN Retrospective case study of 13 primary malignant fibrous histiocytomas (MFH) of the spine. OBJECTIVE To analyze the clinic, radiologic, histologic, and prognostic features of 13 cases with the MFH of the spine. SUMMARY OF BACKGROUND DATA MFH, a soft tissue sarcoma, rarely occurs at the spine. Only sporadical cases have been reported in the English literature concerning the clinical and prognostic features of the primary MFH at the spine. METHODS Between January 1999 and December 2006, 13 cases with primary MFH of the spine were treated in the authors' spine center. Clinical history, radiographic, surgery resection, and pathologic features were recorded. The patients were followed up regarding their local recurrence and survivals. The 17 cases with primary MFH at the spine in the literature were reviewed. RESULTS Paraspinal or epidural mass at multiple spinal levels developed in 11 cases, with osteolytic destruction in all 13 cases. The tumor size averaged on 10.4 cm in greatest dimension. Metastases occurred in 10 of 13 cases. Compared with the 14 ± 0.60-months median survival of the debulking surgeries in seven cases, the median survival of the en bloc resection in six cases was 25 ± 6.12 months (P ∇ 0.009). The median survival was 8.7 months in 10 cases of the literature group, with 30% 1-year survival and 6.7% 2-year survival, respectively; while the median survival was 18.0 months in the authors' series, with 92.3% 1-year survival and 38.5% 2-year survival, respectively. The 5-year survival was between 25% and 69% in the extremities of MFH, but it was 28% in the head and neck and 26.7% in the abdominal cavity, compared with 7.7% in the spine in the authors' series. CONCLUSION The MFH of the spine tends to extensively invade paraspinal structures at multiple spinal levels, with aggressive osteolytic destruction in the vertebrae, resulting to local huge mass, radiculopathy, and myelopathy. Regardless of recent advancements in the diagnosis, treatment methods, and adjuvant therapies, for its biologically aggressive nature, it frequently recurs at the primary site and metastasizes. It has a worse prognosis than that of MFH in other sites.

Abstract
INTRODUCTION The descriptions of total spondylectomy and further development of the technique for the treatment of vertebral sarcomas offered for the first time the opportunity to achieve oncologically sufficient resection margins, thereby improving local tumor control and overall survival. Today, single level en bloc spondylectomies are routinely performed and discussed in the literature while only few data are available for multi-level resections. However, due to the topographic vicinity of the spinal cord and large vessels, the multisegmental resections are technically demanding, represent major surgery and only few case reports are available. Surgical options are even more limited in cases of revision surgery and local recurrences when en bloc spondylectomy was considered to be not feasible due to high risk of vital complications in expanding resection margins. Deranged anatomy, implants in situ and extensive intra-/paraspinal scar tissue formation resulting from previously performed approaches and/or radiation are considered the principal complicating factors that usually hold back spine surgeons to perform revision for resection leaving the patient to palliative treatment. METHODS We present two patient cases with previously performed piecemeal vertebrectomy in the thoracic spine due to a solitary high-grade spinal sarcoma. After extensive re-staging, both patients underwent a multi (4)-level en bloc spondylectomy in our department (one patient with combined en bloc lung resection). Except a local wound disturbance, there was no severe intra- or postoperative complication. RESULTS After multilevel en bloc spondylectomy both patients showed a good functional outcome without neurological deficits, except those resulting from oncologically scheduled resection of thoracic nerve roots. After a median follow-up of 13 months, there was no local recurrence or distant metastasis. The reconstruction using a posterior screw rod system that is interconnected to an anterior vertebral body replacement with a carbon composite cage showed no implant failure or loosening. In summary, the approach of a multilevel en bloc surgery for revision and oncologically sufficient resection in cases of spinal sarcoma recurrences seems possible. However, interdisciplinary decision making in a tumor board, realistic evaluation of surgical resectability to attain tumor free margins, advanced experiences in spinal reconstructions and involvement of vascular, visceral and thoracic surgical expertise are essential preconditions for acceptable oncological and functional outcome.

Abstract
STUDY DESIGN Retrospective clinical study for patients receiving multilevel en-bloc spondylectomy resection for sarcomas and solitary metastases of the thoracolumbar spine. OBJECTIVE Assess the clinical and radiologic outcome after multilevel en-bloc spondylectomy and reconstruction. SUMMARY OF BACKGROUND DATA Monolevel en-bloc spondylectomies have proven their oncosurgical effectiveness while reports on multilevel resections for extracompartmental tumor localizations are rare. METHODS Patients treated by multilevel en-bloc spondylectomy and restoration with a carbon composite vertebral body replacement system were investigated. Patient charts, and clinical follow-up investigations were analyzed for histopathological tumor origin, preoperative symptoms, surgical peri- and postoperative data, applied adjuvant therapies, as well as the course of disease. Solitary metastases time until occurrence and prognostic scores were evaluated (Tomita/Tokuhashi Score). CT-scans were performed and analyzed at follow up. Oncological status was evaluated including local recurrence rates, cumulative disease specific, and metastases-free survival. RESULTS Multilevel (2-5 segments) en-bloc spondylectomy of the thoracolumbar spine was performed in 20 patients (15 sarcomas and 5 solitary spinal metastases 9 male/11 female, mean age at surgery: 54 ± 15 years.). Wide and marginal surgical margins were achieved in 7 and 13 patients, respectively. Mean follow-up period was 25.0 (9-53) months. Thirteen patients received adjuvant therapy. No implant breakage or loosening was observed. Local recurrence occurred in one patient. Thirteen of the 18 surviving patients showed no evidence of the disease, two died of systemic disease. CONCLUSION Multilevel en-bloc spondylectomy offers a radical resection option for extracompartmental tumor involvement. It provides oncologically adequate resection margins with low local recurrence. However, the procedures are complex; the patient's stress is high and metastatic disease developed in one-third of patients. A judicious patient selection and a realistic feasibility evaluation must precede the decision for surgery. Reconstruction using a carbon composite cage system showed low complication rates and offers advantages for oncosurgical procedures.

Abstract
Primary malignant bone tumors of the vertebral column, i.e., bone sarcomas of the spine, are inherently rare entities. Vertebral osteosarcomas and chordomas represent the largest groups, followed by the incidence of chondro-, fibro-, and Ewing's sarcomas. Detailed clinical and neurological examination, complete radiographic imaging [radiographs, computed tomography (CT), magnetic resonance imaging (MRI)], and biopsy are the decisive diagnostic steps. Oncosurgical staging for spinal tumors can serve as a decision-guidance system for an individual's oncological and surgical treatment. Subsequent treatment decisions are part of an integrated, multimodal oncological concept. Surgical options comprise minimally invasive surgery, palliative stabilization procedures, and curative, wide excisions with complex reconstructions to attain wide or at least marginal resections. The most aggressive mode of surgical resection for primary vertebral column tumors is the total en bloc vertebrectomy, i.e., single- or multilevel en bloc spondylectomy. En bloc spondylectomy involves a posterior or combined anterior/posterior approach, followed by en bloc laminectomy, circumferential (360 degrees) vertebral dissection, and blunt ventral release of the large vessels, intervertebral discectomy and rotation/ en bloc removal of the vertebra along its longitudinal axis. Due to the complex interdisciplinary approach and the challenging surgical resection techniques involved, management of vertebral bone sarcomas is recommended to be performed in specific musculoskeletal tumor centers.

Abstract
In primary tumors of the spine and, with limitations, solitary metastasis, the surgical approach should aim for curative treatment of the disease. Because the prognosis of malignant bone tumors is extremely limited, if an intralesional approach is performed, an extralesional en bloc resection is the treatment of choice. Therefore, it is mandatory to use an appropriate staging system. For the spine, the WBB staging system has been approved, which transfers the principles of the Enneking classification for treating primary malignant tumors of the limb to the spine. After en bloc spondylectomy, rigid and primary stable instrumented dorsoventral reconstruction must be performed - posteriorly with a dual-rod system using pedicle screws, and anteriorly in the ideal case by means of a vertebral body replacement cage. The possibility of extralesional (wide or marginal) resection of spinal tumors depends on tumor size and location. Extralesional resection and, if indicated, other neoadjuvant, adjuvant, or local therapeutic modalities have a strong positive influence on long-term survival rates. A good prognosis for primary tumors is associated with a good response to chemotherapy and extralesional resection. Solitary metastases have a much worse quod vitam prognosis. Therefore, local control of the disease in en bloc resections of solitary metastasis is a second relevant goal, although curative treatment is the primary aim.

Abstract
Object
Sarcomas of the spine are a challenging problem due to their frequent and extensive involvement of multiple spinal segments and high recurrence rates. Gross-total resection to negative margins, with preservation of neurological function and palliation of pain, is the surgical goal and may be achieved using either intralesional resection or en bloc excision. The authors report outcomes of surgery for primary and metastatic sarcomas of the mobile spine in a large patient series.
Methods
A retrospective review of patients undergoing resection for sarcomas of the mobile spine between 1993 and 2005 was undertaken. Sarcomas were classified by histology study results and as either primary or metastatic. Details of the surgical approach, levels of involvement, and operative complications were recorded. Outcome measures included neurological function, palliation of pain, local recurrence, and overall survival.
Results
Eighty patients underwent 110 resections of either primary or metastatic sarcomas of the mobile spine. Twenty-nine lesions were primary sarcomas (36%) and 51 were metastatic sarcomas (64%). Intralesional resections were performed in 98 surgeries (89%) and en bloc resections were performed in 12 (11%). Median survival from surgery for all patients was 20.6 months. Median survival for patients with a primary sarcoma of the spine was 40.2 months and was 17.3 months for patients with a metastatic sarcoma. Predictors of improved survival included a chondrosarcoma histological type and a better preoperative functional status, whereas osteosarcoma and a high-grade tumor were negative influences on survival. Multivariate analysis showed that only a high-grade tumor was an independent predictor of shorter overall survival. American Spinal Injury Association scale grades were maintained or improved in 97% of patients postoperatively, and there was a significant decrease in pain scores postoperatively. No significant differences in survival or local recurrence rates between intralesional or en bloc resections for either primary or metastatic spine sarcomas were found.
Conclusions
Surgery for primary or metastatic sarcoma of the spine is associated with an improvement in neurological function and palliation of pain. The results of this study show a significant difference in patient survival for primary versus metastatic spine sarcomas. The results do not show a statistically significant benefit in survival or local recurrence rates for en bloc versus intralesional resections for either metastatic or primary sarcomas of the spine, but this may be due to the small number of patients undergoing en bloc resections.

Abstract
En bloc spondylectomy is a technique that enables wide or marginal resection of malignant lesions of the spine. Both all posterior techniques as well as combined approaches are reported. Aim of the present study was to analyse the results of 21 patients with malignant lesions of the spine, all treated with en bloc excision in a combined posteroanterior (n = 19) or all posterior approach (n = 2). Twenty-one consecutive patients, operated between 1997 and 2005, were included into this retrospective study. Thirteen patients had primary malignant lesions, eight patients had solitary metastases, all located in the thoracolumbar spine. There were 16 single level, three two-level, one three-level and one four-level spondylectomy. The patients were followed clinically and radiographically (including CT studies) with an average follow-up of 4 years. Out of 11 patients with primary Ewing or osteosarcoma seven patients are alive without any evidence of disease. One patient died after 5 years from other causes and three are alive with evidence of disease. Latter had either a poor histologic response to the preoperative chemotherapy (n = 2) or an intralesional resection (n = 1). All three patients with solitary spinal metastases of Ewing or osteosarcoma died of the disease. Five patients with solitary metastases of mainly hypernephroma are alive. In total, six resections were intralesional, mainly due to large intraspinal tumor masses, with two patients having had previous surgery. In the remaining cases, wide (n = 10) or marginal (n = 5) resection was accomplished. There were one pseudarthrosis requiring extension of the fusion and two cases with local recurrences and repeated excisional surgery. At follow-up CT studies, all cages were fused. Health related quality of life analysis (SF-36) revealed only slightly decreased physical component and normal mental component scores compared to normals in those patients with no evidence of disease. En bloc spondylectomy enables wide or marginal resection of malignant lesions of the spine in most cases with acceptable morbidity. Intralesional resection, poor histologic response, and solitary spinal metastases of Ewing and osteosarcoma are associated with a poor prognosis.

Abstract
Wide surgical margins make en bloc spondylectomy and stabilization a referred treatment for certain tumoral lesions. With a total resection of a vertebra, the removal of the segment's stabilizing structures is complete and the instrumentation guidelines derived from a thoracolumbar corpectomy may not apply. The influence of one or two adjacent segment instrumentation, adjunct anterior plate stabilization and vertebral body replacement (VBR) designs on post-implantational stability was investigated in an in-vitro en bloc spondylectomy model. Biomechanical in-vitro testing was performed in a six degrees of freedom spine simulator using six human thoracolumbar spinal specimens with an age at death of 64 (+/- 20) years. Following en bloc spondylectomy eight stabilization techniques were performed using long and short posterior instrumentation, two VBR systems [(1) an expandable titanium cage; (2) a connected long carbon fiber reinforced composite VBR pedicle screw system)] and an adjunct anterior plate. Test-sequences were loaded with pure moments (+/- 7.5 Nm) in the three planes of motion. Intersegmental motion was measured between Th12 and L2, using an ultrasound based analysis system. In flexion/extension, long posterior fixations showed significantly less range of motion (ROM) than the short posterior fixations. In axial rotation and extension, the ROM of short posterior fixation was equivalent or higher when compared to the intact state. There were only small, nonsignificant ROM differences between the long carbon fiber VBR and the expandable system. Antero-lateral plating stabilized short posterior fixations, but did not markedly effect long construct stability. Following thoracolumbar en bloc spondylectomy, it is the posterior fixation of more than one adjacent segment that determines stability. In contrast, short posterior fixation does not sufficiently restore stability, even with an antero-lateral plate. Expandable verses nonexpandable VBR system design does not markedly affect stability.

Abstract
Primary and metastatic spinal mesenchymal tumors are uncommon lesions. Surgical management of these tumors remains a challenge. En bloc wide resection provides the best chance for local tumor control and long-term survival. However, limitations to this technique include technical considerations (including neurovascular anatomy), patient selection, and tumor histology. Intralesional resection provides good neurologic outcomes, but local recurrence rates are high. Postoperative adjuvant chemotherapy with or without radiation may help to delay recurrence and improve outcomes. We present three cases of our surgical experience with spinal mesenchymal tumors for illustrative purposes.

Abstract
Primary malignant spinal tumors and solitary vertebral metastases of selected tumor entities in the thoracolumbar spine are indications for total en bloc spondylectomy (TES). This study aimed to describe our oncological and surgical management and to analyze the treatment results by management with TES for extra- and intracompartmental solitary spinal metastases and primary malignant vertebral bone tumors. In 15 patients (3 malignant bone tumors and 12 solitary metastases), tumors were distributed in the thoracic (n = 8) and lumbar (n = 7) spine. Tumors were classified as intra- (n = 8) and extracompartmental (n = 7). All patients underwent TES via a laterally extended posterior approach followed by dorsoventral reconstruction. Function and quality of life were assessed by Oswestry disability index (ODI) and SF-36 score. At follow-up (100%; mean: 33 +/- 22 months), 11 patients had no evidence of disease. Two patients were alive with the disease and two were dead of the disease (no primary bone tumors). Histology revealed negative margins (R0) in all patients with wide (n = 11) and marginal (n = 4) resections. Two patients developed pulmonal metastases of which they died at 4 and 16 months of survival. No local recurrence was observed. Major complications did not occur. TES resulted in an acceptable outcome in the quality of life and function. TES is a demanding procedure reaching wide to marginal resections in a curative approach. In conjunction with multimodal therapies, local recurrences can effectively be prevented while control of distant disease needs to be improved. Proper selection of adequate patients combined with careful surgical planning are prerequisites for low complication rates, acceptable function and improved overall prognosis.

Abstract
STUDY DESIGN Description of surgical technique and retrospective review of 13 cases. OBJECTIVES To describe the surgical technique of margin-free spondylectomy and the outcome of 13 cases and to discuss the advantages and limitations of the procedure. SUMMARY OF BACKGROUND DATA Recently, spondylectomy became a standard procedure by several pioneers. For extended malignant spine tumors involving pedicles or epidural space, however, performing an "en bloc" resection with a tumor-free margin remains a challenge. METHODS Our procedure consists of a combined anterior and posterior procedure with one or two stages. In the anterior procedure, tumor vertebrae are covered by the pleura or psoas muscles as a barrier. The posterior procedure includes decompression through the intact posterior elements, coverage of the tumor with all possible soft tissue barriers, and en bloc extirpation by rotating the tumor vertebrae around the spinal cord. We performed this procedure in 13 cases: 3 chondrosarcoma, 3 giant cell tumor, 1 osteosarcoma, 1 chordoma, and 5 metastases. RESULTS Neurologic status and pain improved in all cases except asymptomatic cases. There was no local recurrence, except in 2 cases (chondrosarcoma with extirpation of 5 vertebrae, chordoma with multiple previous surgeries). Two cases of chondrosarcoma were disease-free 14 years and 13 years after surgery, respectively. CONCLUSION Although the best chance for a cure in extended malignant tumors of the spine is realized through wide resection, the procedure is not yet standardized. Margin-free spondylectomy is technically demanding, but the procedure can be used with a confidence as a more radical surgery for tumors extending to the epidural space and the unilateral pedicle. A key to success is the surgical technique, including a 360 degree dissection around the tumor vertebrae, instrumentation, and removal of the lesion with all possible soft tissues maintained intact to function as a barrier, like the dura mater.

Abstract
✓ The purpose of this case report is to demonstrate that an en bloc resection with negative surgical margins can be successfully achieved in a case of a seemingly unresectable C-2 chordoma if appropriate preoperative staging and planning are performed. The management of chordomas is controversial and challenging because of their location and often large size at presentation. Because chordomas are malignant and will aggressively recur locally if intralesional resection is conducted, wide or true en bloc resection is generally recommended. The literature indicates, however, that surgeons are reluctant to perform wide or even marginal resections because of the lesion’s complex surrounding anatomy and the risk of significant neurological compromise when a tumor abuts the dura mater or neural tissues. In this report the authors outline the successful en bloc resection of a large C1–3 chordoma and discuss the importance of preoperative staging and planning.

Abstract
STUDY DESIGN Resection of a primary malignant tumor of the bone with wide surgical margins has become the golden standard in oncological surgery. In the case of a spinal tumor with tumor invasion of the spinal canal, a wide resection could necessitate resection and subsequent replacement of part of the dura. SUMMARY OF BACKGROUND DATA Dura replacement is a consequent surgical step in the treatment of primary malignant tumors of the spine. METHODS We present the case of a 27-year-old male with a tumor of the dorsal elements of D6. After paraplegic symptoms, a laminectomy of D5 to D7 was performed and histologic examination revealed the presence of an osteosarcoma. After neoadjuvant polychemotherapy, a wide resection of the dorsal elements from D4 to D7 combined with a resection of the dorsal part of the dura was planned. Replacement of the dura was performed with Lyodura (B. Braun Melsungen AG, Melsungen, Germany). The spine was stabilized with an ISOLA instrumentation (Depuy International Ltd., Leeds, England). For wound closure, a pedicled latissimus dorsi flap and split skin graft were necessary. In a second step, ventral spondylodesis with Texas Scottish Rite Hospital instrumentation (Sofamor Danek, Memphis, TN) was performed. RESULTS One hundred sixteen months after surgery the patient is alive without evidence of disease, is pain free, and has returned to his profession and life without any restrictions.
