INTRODUCTION: Brown-Séquard syndrome due to a stab injuries is uncommon and results from a lesion in one half of the spinal cord. BACKGROUND: The role of surgery in the treatment of penetrating spinal injury often remain controversial. AIM: To discuss the current diagnostic and therapeutic approach for these types of injuries. MATERIALS AND METHODS: The Authors describe two rare cases of Brown-Séquard syndrome due to civilian stab injuries differently treated. Mechanism of damage, clinical features and neurological outcome are reported. RESULTS: The recovery of neurological function in the first case indicates that the spinal tracts were injured by a contusion, rather than by a direct injury as in the second case. Moreover, surgery was required in the second patient to remove the weapon and to stabilize the spine, presenting bony and ligamentous instability. DISCUSSION: The diagnostic and therapeutic management are debated. An overview on clinical research in sperimental medical treatment of spinal cord injury was considered to evaluate future possible approaches to these injuries. CONCLUSIONS: As the neurologic improvement depends on the type and severity of the spinal cord damage, the indications for acute surgical management are limited and conservative management should be preferred.

BACKGROUND: Rehabilitation is a crucial issue in the management of spinal cord injuries (SCI) but, in these patients, the primary treatment can bias the outcome of recovery protocols. AIM: Purpose of this paper is to review our case load in the treatment of surgical failures and to define the role of surgery in thoraco-lumbar injuries rehabilitation. PATIENTS AND METHODS: Between 2000 and 2009 seventy patients with post-traumatic paraplegia were referred to Surgical Department as rehabilitation was unfeasible due to inadequate spine injury treatment. Forty-six had had surgery, 24 were treated conservatively Twenty-five patients had a thoracic lesion, 9 a lumbar lesion and 36 a lesion of the thoraco-lumbar junction. A total of 44 surgical procedures were performed (by anterior, posterior or anterior-posterior). RESULTS: On postoperative imaging sagittal alignment was found good in 93% of cases and acceptable in 7%. All patients regained the sitting position within 5 days after surgery. Wound healing problems requiring revision were observed in 4 cases. Major complications were a cerebro spinal fluid (CSF) leakage and a massive pulmonary embolism case in the early post-op. CONCLUSIONS: Wrong primary treatment frequently leads to demanding revision procedures with increased risks for the patient and more than double costs for the health care system. Whatever the technique a stable spine is the target in surgery of SCI allowing a quick and effective rehabilitation without external orthosis. [ABSTRACT FROM AUTHOR]

Background: The early management of polytrauma patients with traumatic spinal cord injury (tSCI) is a major challenge. Sparse data is available to provide optimal care in this scenario and worldwide variability in clinical practice has been documented in recent studies., Methods: A multidisciplinary consensus panel of physicians selected for their established clinical and scientific expertise in the acute management of tSCI polytrauma patients with different specializations was established. The World Society of Emergency Surgery (WSES) and the European Association of Neurosurgical Societies (EANS) endorsed the consensus, and a modified Delphi approach was adopted., Results: A total of 17 statements were proposed and discussed. A consensus was reached generating 17 recommendations (16 strong and 1 weak)., Conclusions: This consensus provides practical recommendations to support a clinician's decision making in the management of tSCI polytrauma patients., (© 2024.

The aim of this study was to determine whether early surgical treatment results in better neurological recovery 12 months after injury than late surgical treatment in patients with acute traumatic spinal cord injury (tSCI). Patients with tSCI requiring surgical spinal decompression presenting to 17 centres in Europe were recruited. Depending on the timing of decompression, patients were divided into early (≤ 12 hours after injury) and late (> 12 hours and < 14 days after injury) groups. The American Spinal Injury Association neurological (ASIA) examination was performed at baseline (after injury but before decompression) and at 12 months. The primary endpoint was the change in Lower Extremity Motor Score (LEMS) from baseline to 12 months. The final analyses comprised 159 patients in the early and 135 in the late group. Patients in the early group had significantly more severe neurological impairment before surgical treatment. For unadjusted complete-case analysis, mean change in LEMS was 15.6 (95% confidence interval (CI) 12.1 to 19.0) in the early and 11.3 (95% CI 8.3 to 14.3) in the late group, with a mean between-group difference of 4.3 (95% CI -0.3 to 8.8). Using multiply imputed data adjusting for baseline LEMS, baseline ASIA Impairment Scale (AIS), and propensity score, the mean between-group difference in the change in LEMS decreased to 2.2 (95% CI -1.5 to 5.9). Compared to late surgical decompression, early surgical decompression following acute tSCI did not result in statistically significant or clinically meaningful neurological improvements 12 months after injury. These results, however, do not impact the well-established need for acute, non-surgical tSCI management. This is the first study to highlight that a combination of baseline imbalances, ceiling effects, and loss to follow-up rates may yield an overestimate of the effect of early surgical decompression in unadjusted analyses, which underpins the importance of adjusted statistical analyses in acute tSCI research., Competing Interests: The authors have no conflicts of interest to declare., (© 2023 Author(s) et al.)

Study Design: Retrospective multicenter., Objectives: diffuse idiopathic skeletal hyperostosis (DISH) involving the cervical spine is a rare condition determining disabling aero-digestive symptoms. We analyzed impact of preoperative settings and intraoperative techniques on outcome of patients undergoing surgery for DISH., Methods: Patients with DISH needing for anterior cervical osteophytectomy were collected. Swallow studies and endoscopy supported imaging in targeting bone decompression. Patients characteristics, clinico-radiological presentation, outcome and surgical strategies were recorded. Impact on clinical outcome of duration and time to surgery and different surgical techniques was evaluated through ANOVA., Results: 24 patients underwent surgery. No correlation was noted between specific spinal levels affected by DISH and severity of pre-operative dysphagia. A trend toward a full clinical improvement was noted preferring the chisel ( P = 0.12) to the burr ( P = 0.65), and whenever C2-C3 was decompressed, whether hyperostosis included that level ( P = 0.15). Use of curved chisel reduced the surgical times ( P = 0.02) and, together with the nasogastric tube, the risk of complications, while bone removal involving 3 levels or more ( P = 0.04) and shorter waiting times for surgery ( P < 0.001) positively influenced a complete swallowing recovery. Early decompressions were preferred, resulting in 66.6% of patients reporting disappearance of symptoms within 7 days. One and two recurrences respectively at clinical and radiological follow-up were registered 18-30 months after surgery., Conclusion: The "age of DISH" counts more than patients' age with timeliness of decompression being crucial in determining clinical outcome even with a preoperative mild dysphagia. Targeted bone resections could be reasonable in elderly patients, while in younger ones more extended decompressions should be preferred.

Background: Compression injuries of the thoracolumbar spine without neurological impairment are usually treated with minimally invasive procedures. Intravertebral expandable implants represent an alternative strategy in fractures with low fragments' displacement., Methods: Patients with A2, A3 and A4 fractures of the T10-L2 spinal segment without neurological impairment, fracture gap >2 mm, vertebra plana, pedicle rupture, pedicle diameter <6 mm, spinal canal encroachment ≥50%, and vertebral body spread >30% were treated with the SpineJack device. Patients with pathological/osteoporotic fractures were excluded. Demographic and fracture-related data were assessed together with vertebral kyphosis correction, vertebral height restoration/loss of correction and final kyphosis. The modified Rankin Scale (mRS), Oswestry Disability Index (ODI), Visual Analogue Scale (VAS), Smiley-Webster Pain Scale (SWPS) and EuroQol-5D (EQ-5D) were evaluated at 1 (-post), 6 and 12 months (-fup) after surgery. Statistical analysis was performed and p values ≤0.05 were considered significant., Results: Fifty-seven patients were included in the study. Patients aged >60 years reported worse kyphosis correction (<4°) with more postoperative complications, while vertebral plasticity in younger patients, fragmentation-related greater remodeling in A3/A4 fractures, and treatments within 7 days of trauma determined superior wedging corrections, with better EQ-5D-post and mRS-fup. Cement leakages did not affect functional outcome, while female gender and American Society of Anesthesiologists (ASA) score of 3-4 were associated with worse ODI-fup and VAS-fup. Although fracture characteristics and radiological outcome did not negatively influence the clinical outcome, A2 fracture was a risk factor for complications, thus indirectly compromising both the functional and radiological outcome., Conclusion: With spread of <30%, the SpineJack is an alternative to minimally invasive fixations for treating A3/A4 thoracolumbar fractures, being able to preserve healthy motion segments in younger patients and provide an ultra-conservative procedure for elderly and fragile patients., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Conservative treatment is commonly accepted and widely used for most atlas compression fractures. Malunion due to mismatching of the articular surfaces in C0-C1 and C1-C2 is therefore frequent even without associated instability. Such a result is considered acceptable in the elderly with low functional requests but should be avoided in young patients. Authors describe a new surgical technique to reduce and fix a nonunion and malunited fracture of the atlas through a posterior arch osteotomy followed by articular masses stabilization with polyaxial screws and precurved titanium rod. Rod prebending reduces lateral inclination of the screw heads during the reduction maneuver through compression applied between screw heads making it effective., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Case: We present a 36-year-old man with L1 burst fracture after a sneeze. He was in follow-up for indolent systemic mastocytosis (ISM), and osteoporosis was treated with bisphosphonate. Owing to neurologic impairment, posterior decompressive laminectomy and thoraco-lumbar fusion with cemented screws were performed., Conclusion: Vertebral fractures in young patients affected by ISM required a multidisciplinary approach and a careful preoperative planning to achieve acceptable results. These fractures are so rare that even an experienced spine surgeon may not come across them during his whole career. Nevertheless, diagnostic tool improvement makes its diagnosis more frequent, that is why every spine surgeon should know this disease., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSCC/B653)., (Copyright © 2021 by The Journal of Bone and Joint Surgery, Incorporated.)

Study Design: Retrospective multicenter study., Objective: Analysis of impact of conservative and surgical treatments on functional outcome of geriatric odontoid fractures., Summary of Background Data: Treatment of odontoid fractures in aged population is still debatable., Methods: One hundred fourty-seven consecutive odontoid fractures in elderly patients were classified according to Anderson-D'Alonzo and Roy-Camille classifications. Philadelphia type collar was always positioned and kept as a treatment whenever acceptable. Halo-vest, anterior screw fixation, C1-C2 posterior arthrodesis, and occipito-cervical fixation were the other treatments adopted. Conservative or surgical treatment strategy was more significantly influenced by antero-posterior displacement (< or >5 mm) and by surgeon decision. On admission ASA, modified Rankin scale (mRS-pre) and Charlson Comorbidity Index (CCI) were assessed. Modified Rankin scale (mRS-post), Neck Disability Index (NDI), and Smiley Webster Pain Scale (SWPS) were administered 12 to 15 months after treatment to estimate functional outcome in terms of general disability, neck-related disability, and ability to return to work/former activity. Risk of treatment crossover was calculated considering factors affecting outcome. Fracture healing process in terms of fusion-stability, no fusion-stability, no fusion-no stability was evaluated at 12 months through a cervical computed tomography (CT) scan. Dynamic cervical spine x-rays were obtained whether necessary. No fusion-stability was considered an adequate treatment goal in our geriatric population. Chi square/Fisher exact test and logistic regression were performed for statistical anal., Results: Overall 67 patients were treated conservatively whereas 80 underwent surgery. Collar was adopted in 45 patients, while anterior odontoid fixation and C1-C2 posterior arthrodesis were preferred for 30 patients each. 79.8% of patients showed good outcomes according to NDI. No significant differences were observed between patients of 65 to 79 years and more than or equal to 80 years (P = 0.81). CCI greatly correlated with mRS-post, with higher indexes in 68.8% of cases characterized by good outcomes (P = 0.05). mRS-pre correlated with NDI (P < 0.000001) and mRS-post (P = 0.04). CCI, mRS-pre, and surgery were associated with worse NDI, while both C1-C2 posterior arthrodesis and occipito-cervical stabilization were associated with worse mRS-post, respectively in 40% and 30% of cases. Younger patients had a higher risk of treatment crossover., Conclusion: mRS-pre and CCI provided two independent predictive values respectively for functional outcome and post-treatment disability. Compared with conservative immobilizations, surgery revealed no advantages in the elderly in terms of functional outcome., Level of Evidence: 3.

Purpose: Analysis of functional outcome of elderly patients with type II odontoid fractures treated conservatively in relation to their radiological outcome., Methods: A total of 50 geriatric patients with type II odontoid fractures were treated with Aspen/Vista collars. On admission, each patient was assessed assigning ASA score, modified Rankin Scale (mRS-pre) and Charlson Comorbidity Index (CCI). From 12-15 months after treatment, functional evaluations were performed employing a second modified Rankin Scale (mRS-post) together with Neck Disability Index (NDI) and Smiley-Webster pain scale (SWPS). Radiological outcome was evaluated through dynamic cervical spine X-rays at 3 months and cervical spine CT scans 6 months after treatment. Three different conditions were identified: stable union, stable non-union and unstable non-union. Surgery was preferred whenever a fracture gap > 2 mm, an antero-posterior displacement > 5 mm, an odontoid angulation > 11° or neurological deficits occurred., Results: Among the 50 patients, 24 reached a stable union, while 26 a stable non-union. Comparing the two groups, no differences in ASA (p = 0.60), CCI (p = 0.85) and mRS-pre (p = 0.14) were noted. Similarly, no differences in mRS-post (p = 0.96), SWPS (p = 0.85) and NDI (p = 0.51) were observed between patients who reached an osseous fusion and those with a stable fibrous non-union. No effects of age, sex, ASA, mRS-pre, fracture dislocation and radiological outcome were discovered on functional outcome. At logistic regression analysis, female sex and high values of CCI emerged associated with worse NDI., Conclusions: In geriatric type II odontoid fractures, pre-injury clinical status and comorbidities overcome imaging in determining post-treatment level of function. Hard collar immobilization led to a favourable functional outcome with mRS-post, NDI and SWPS values diffusely encouraging whatever a bony union or a fibrous non-union was obtained.

Background Context: The load sharing classification (LSC) laid foundations for a scoring system able to indicate which thoracolumbar fractures, after short-segment posterior-only fixations, would need longer instrumentations or additional anterior supports., Purpose: We analyzed surgically treated thoracolumbar fractures, quantifying the vertebral body's fragment displacement with the aim of identifying a new parameter that could predict the posterior-only construct failure., Study Design: This is a retrospective cohort study from a single institution., Patient Sample: One hundred twenty-one consecutive patients were surgically treated for thoracolumbar burst fractures., Outcome Measures: Grade of kyphosis correction (GKC) expressed radiological outcome; Oswestry Disability Index and visual analog scale were considered., Methods: One hundred twenty-one consecutive patients who underwent posterior fixation for unstable thoracolumbar burst fractures were retrospectively evaluated clinically and radiologically. Supplementary anterior fixations were performed in 34 cases with posterior instrumentation failure, determined on clinic-radiological evidence or symptomatic loss of kyphosis correction. Segmental kyphosis angle and GKC were calculated according to the Cobb method. The displacement of fracture fragments was obtained from the mean of the adjacent end plate areas subtracted from the area enclosed by the maximum contour of vertebral fragmentation. The "spread" was derived from the ratio between this subtraction and the mean of the adjacent end plate areas. Analysis of variance, Mann-Whitney, and receiver operating characteristic were performed for statistical analysis. The authors report no conflict of interest concerning the materials or methods used in the present study or the findings specified in this paper. No funds or grants have been received for the present study., Results: The spread revealed to be a helpful quantitative measurement of vertebral body fragment displacement, easily reproducible with the current computed tomography (CT) imaging technologies. There were no failures of posterior fixations with preoperative spreads <42% and losses of correction (LOC)<10°, whereas spreads >62.7% required supplementary anterior supports whenever LOC>10° were recorded. Most of the patients in a "gray zone," with spreads between 42% and 62.7%, needed additional anterior supports because of clinical-radiological evidence of impending mechanical failures, which developed independently from the GKC. Preoperative kyphosis (p<.001), load sharing score (p=.002), and spread (p<.001) significantly affected the final surgical treatment (posterior or circumferential)., Conclusions: Twenty-two years after the LSC, both improvements in spinal stabilization systems and software imaging innovations have modified surgical concepts and approach on spinal trauma care. Spread was found to be an additional tool that could help in predicting the posterior construct failure, providing an objective preoperative indicator, easily reproducible with the modern viewers for CT images., (Copyright © 2017 Elsevier Inc.

Introduction: The goal of the study was to evaluate both clinical and radiological outcome of a consecutive series of 11 patients submitted to lumboiliac fixation after lumbopelvic disjunction or associated injuries of the pelvis and lumbosacral tract in mid- and long-term follow-up., Material and Methods: The following were evaluated from clinical charts: damage control preoperative procedures, surgery, and pre-, intra- and post-operative complications; imaging was also evaluated from the preoperative assessment to the final follow-up (4 to 13.2 years; average 7.2 years)., Results: One patient died a few days after surgery; therefore, long-term follow-up was possible in 10 patients. One of the 10 patients could be evaluated only radiologically because he was non-compliant due to severe mental illness. There were four early complications: one patient had a massive pulmonary embolism, which was fatal; one had wound dehiscence; one developed pulmonary infection and one had caecal fistula, which was repaired by the general surgeon. Late complications were as follows: three patients required hardware removal or substitution because of deep infection (after 1year), system breakage (after 9 years) and screws loosening (after 7 years). Clinical evaluation was available in nine patients and was assessed using Oswestry forms and a Visual Analogue Scale (VAS). All patients were able to walk at least 1 kilometre without external support, two patients were using pain medication regularly and three patients were classified with severe disability at final follow-up. Degenerative changes in the joints close to the fused area were observed in two patients more than 10 years after the operation, but the correlation with surgery is questionable., Discussion: Lumbopelvic disjunctions generally follow high-energy trauma often involving internal thoracic and abdominal organs; therefore, a well-trained team approach is mandatory to preserve patient life and to provide adequate treatment of skeletal injuries. Mechanical complications may occur several years after surgery, thus a long-term follow-up is mandatory., Conclusions: Lumbopelvic fixation is an effective surgical technique for treatment of spinopelvic disjunction. The patient numbers in this series, and in the literature in general, are low; therefore, a multicentre study is advisable to give evidence and statistical importance to our findings., (Copyright © 2016 Elsevier Ltd.

Type and timing of treatment for symptomatic hemangiomas in pregnant females are challenging due to fetus survival and conflicts in neurological recovery. In this article, we report a 40-year-old female patient at pregnancy week 23 with a complicated hemangioma at T1 level. Physical examination revealed an incomplete spastic paraplegia. Patient did not accept any surgery due to child's death risk. Patient was started corticoid treatment and no more weight bearing was allowed. At the 28th week of pregnancy, the patient underwent cesarean section immediately followed by selective arterial embolization, decompression, fixation, and radiotherapy. At two-year follow-up, the patient was pain free, without any signs of local recurrence and with complete neurological recovery. A multidisciplinary approach is mandatory to save the life of the fetus without damaging the spinal cord functions of the mother.

Background Context: Spinal implant placement may be challenging in cases of severe cervicothoracic spinal deformities and anatomical anomalies as in Type 1 neurofibromatosis. Intralaminar screwing of the thoracic spine has been described in few cases in which pedicles were hypoplasic. The costovertebral joints have never been used before as an anchorage point for screws., Purpose: The purpose of the study was to describe a new thoracic fixation technique to be used in severe deformities whenever the posterior arch (laminae and pedicles) is not available because of anatomic abnormalities., Study Design: This is a case report., Methods: An 18-year-old woman with progressive tetraparesis caused by increasing deformity of cervicothoracic spine underwent evaluation and surgical treatment: procedure and techniques were described. The clinical features, the radiological findings, and the outcomes were assessed. Complications and local recurrences were also recorded., Results: Costotransverse joint screwing was successfully used in one case of severe cervicothoracic spine deformity with major hypoplasia of the pedicles. The posterior arch of one thoracic vertebra became mobile soon after periosteal stripping probably because of iatrogenic fracture of the only existent pedicle. The four-cortical trajectory of the screws resulted in a good bone purchase allowing the surgeon to complete the procedure. No local or general complications were recorded during 2 years of follow-up., Conclusions: The procedure was used as a salvage technique during a difficult surgery where a local complication forced a change of strategy. Although the implant remained stable long enough to achieve fusion, it still consists of placing a screw through a joint that remains slightly mobile. This could possibly result in a screw loosening in the long period if fusion is not achieved. We suggest the use of this technique when all the other options have been explored and excluded for anatomical reasons., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Background Context: Many studies have demonstrated that en bloc surgical resection of primary spinal tumors with adequate margins results in improved local disease control and survival compared with intralesional excision. Nevertheless, the use of this procedure is under debate because most of the current evidence is provided by small and heterogeneous series of cases., Purpose: To validate the application of en bloc resection for the treatment of aggressive benign and primary malignant spinal tumors., Study Design: This is a prospective cohort study., Patient Sample: From August 1990 to March 2010, 103 consecutive patients affected by primary spinal tumors were enrolled in the study. All patients were submitted to the same clinical and imaging workup., Outcome Measures: Analysis of local recurrence (LR) and tumor-related mortality, reliability of preoperative surgical planning, and morbidity and mortality. In addition, the effects of possible predictors of these events were studied., Methods: The parameters for the effectiveness and safety of en bloc resections performed on primary spinal tumors were considered as primary end points of this study, and two research questions were formulated. The analysis of the procedure effectiveness considered the identification of possible predictors of LR and tumor-related mortality. Information about safety is collected so as to clarify the possibility to respect the preoperative planning and to identify possible predictors of morbidity and mortality. Data from clinical and imaging examination were collected in a database and were used to answer the proposed research questions., Results: All patients were followed for a minimum of 24 months or until death. At the final assessment, 69 patients resulted with no evidence of disease with a mean follow-up of 100 months. Among the 103 patients, tumor recurred in 22 cases with a mean follow-up period of 39 months after surgery. A Cox regression multivariate analysis shows that marginal and intralesional resections are independent predictors of LR (hazard ratio [HR] 9.45, 95% confidence interval [CI] 1.06-84.47 and HR 38.62, 95% CI 4.67-319.21, respectively, compared with wide resection) and tumor-related mortality (in particular, HR 17.10, 95% CI 3.80-77.04 for intralesional resection compared with the wide one). The same analysis demonstrates that en bloc resection performed in recurrent cases or patients previously submitted to open biopsy (nonintact cases) have a LR risk higher than intact cases (HR 3.45, 95% CI 1.38-8.63). The success rate of en bloc resections in achieving adequate margins is 82.4%, and Weinstein-Boriani-Biagini surgical staging can also predict the margins in a high percentage of cases (75.7%). Complications occurred in 41.7% of patients with a higher rate observed in the nonintact group and for surgery with a double-approach or multisegmental resections. The mortality rate related to surgery complications was 1.9%, whereas tumor-related mortality was 15.5%., Conclusions: Statistical analysis of the long-term results referred to 103 patients affected by aggressive benign and malignant primary spine tumors indicates that an en bloc resection is associated with a high rate of complications. Nevertheless, it decreases the risk of LR and tumor-related mortality. En bloc resection is a highly demanding procedure but can be performed to an acceptable degree of safety., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Purpose: To analyze the role of spine alignment in post-traumatic paraplegic patient as a potential cause of late Charcot spine disease (CSD)., Method: A retrospective review of three cases in which the disease appeared more than 15 years after a spinal cord injury treated by posterior fusion. A review of the literature concerning spine balance in sitting position, especially referred to paraplegic patients, is done to validate this hypothesis., Results: Lumbar kyphosis in paraplegic patients during the sitting position may increase the mechanical load on disks and ligament below the previously fused area. This phenomenon, in combination with lack of protective mechanism because of poor muscular support and lack of sensitivity can speed up and amplify the normal degenerative changes in the disk and ligaments., Conclusions: More investigations are required to fully understand all the mechanisms underlying CSD pathogenesis to prevent it. Until then, a systematic long-term clinical and radiological follow-up in all post-trauma paraplegic patients is suggested. Combined anterior and posterior fusion, when feasible, can restore the sagittal balance providing a better quality of life in these patients.
