RESUMO

Achondroplasia is an autosomal dominant disorder with defect in the ossification of the cartilage of long bones. Many bony abnormalities constitute its clinical features, with craniovertebral junction (CVJ) anomalies being one of most common issues which need to be addressed at the earliest. CVJ anomalies in individuals may cause neurovascular compression, which may warrant an early surgery to prevent catastrophic complications. Posterior circulation strokes secondary to CVJ anomalies are well known. We hereby present an unusual case of posterior circulation stroke in an achondroplastic dwarf who presented to our tertiary care centre. Prospective case study. The present case adds to the existing literature about one of the preventable causes of fatal posterior circulation strokes in the young. A high index of suspicion for neurovascular compression at the foramen magnum and early initiation of treatment in achondroplastic young individuals may have gratifying results.

RESUMO

Introduction: Symptomatic acute metastatic spinal epidural cord compression (MSCC) is an emergency that requires multimodal attention. However, there is no clear consensus on the appropriate timing for surgery. Therefore, to address this issue, we conducted a systematic review and meta-analysis of the literature to evaluate the outcomes of different surgery timings. Methods: We searched multiple databases for studies involving adult patients suffering from symptomatic MSCC who underwent decompression with or without fixation. We analyzed the data by stratifying them based on timing as emergent (≤24 h vs. >24 h) and urgent (≤48 h vs. >48 h). The analysis also considered adverse postoperative medical and surgical events. The rates of improved outcomes and adverse events were pooled through a random-effects meta-analysis. Results: We analyzed seven studies involving 538 patients and discovered that 83.0% (95% CI 59.0-98.2%) of those who underwent urgent decompression showed an improvement of ≥1 point in strength scores. Adverse events were reported in 21% (95% CI 1.8-51.4%) of cases. Patients who underwent emergent surgery had a 41.3% (95% CI 20.4-63.3%) improvement rate but a complication rate of 25.5% (95% CI 15.9-36.3%). Patients who underwent surgery after 48 h showed 36.8% (95% CI 12.2-65.4%) and 28.6% (95% CI 19.5-38.8%) complication rates, respectively. Conclusion: Our study highlights that a 48 h window may be the safest and most beneficial for patients presenting with acute MSCC and a life expectancy of over three months.

RESUMO

BACKGROUND: To our knowledge, there is no previous report in the literature of non-traumatic neglected complete cervical spine dislocation characterized by anterior spondyloptosis of C4, extreme head drop, and irreducible cervicothoracic kyphosis. CASE PRESENTATION: We report the case of a 33-year-old Caucasian man with a 17-year history of severe immune polymyositis and regular physiotherapy who presented with severe non-reducible kyphosis of the cervicothoracic junction and progressive tetraparesia for several weeks after a physiotherapy session. Radiographs, computed tomography, and magnetic resonance imaging revealed a complete dislocation at the C4-C5 level, with C4 spondyloptosis, kyphotic angulation, spinal cord compression, and severe myelopathy. Due to recent worsening of neurological symptoms, an invasive treatment strategy was indicated. The patient's neurological status and spinal deformity greatly complicated the anesthetic and surgical management, which was planned after extensive multidisciplinary discussion and relied on close collaboration between the orthopedic surgeon and the anesthetist. Regarding anesthesia, difficult airway access was expected due to severe cervical angulation, limited mouth opening, and thyromental distance, with high risk of difficult ventilation and intubation. Patient management was further complicated by a theoretical risk of neurogenic shock, motor and sensory deterioration, instability due to position changes during surgery, and postoperative respiratory failure. Regarding surgery, a multistage approach was carefully planned. After a failed attempt at closed reduction, a three-stage surgical procedure was performed to reduce displacement and stabilize the spine, resulting in correct spinal realignment and fixation. Progressive complete neurological recovery was observed. CONCLUSION: This case illustrates the successful management of a critical situation based on a multidisciplinary collaboration involving radiologists, anesthesiologists, and spine surgeons.

RESUMO

Objectives and Background: To present a novel technique of treatment for a patient with basilar invagination. Basilar invagination (BI) is a congenital condition that can compress the cervicomedullary junction, leading to neurological deficits. Severe cases require surgical intervention, but there is debate over the choice of approach. The anterior approach allows direct decompression but carries high complication rates, while the posterior approach provides indirect decompression and offers good stability with fewer complications. Materials and Methods: A 15-year-old boy with severe myelopathy presented to our hospital with neck pain, bilateral upper limb muscle weakness, and hand numbness persisting for 4 years. Additionally, he experienced increased numbness and gait disturbance three months before his visit. On examination, he exhibited hyperreflexia in both upper and lower limbs, muscle weakness in the bilateral upper limbs (MMT 4), bilateral hypoesthesia below the elbow and in both legs, mild urinary and bowel incontinence, and a spastic gait. Radiographs revealed severe basilar invagination (BI). Preoperative images showed severe BI and that the spinal cord was severely compressed with odontoid process. Results: The patient underwent posterior surgery with the C-arm free technique. All screws including occipital screws were inserted into the adequate position under navigation guidance. Reduction was achieved with skull rotation and distraction. A follow-up at one year showed the following results: Manual muscle testing results and sensory function tests showed almost full recovery, with bilateral arm recovery (MMT 5) and smooth walking. The cervical Japanese Orthopedic Association score of the patient improved from 9/17 to 16/17. Postoperative images showed excellent spinal cord decompression, and no major or severe complications had occurred. Conclusions: Basilar invagination alongside Klippel-Feil syndrome represents a relatively uncommon condition. Utilizing a posterior approach for treating reducible BI with a C-arm-free technique proved to be a safe method in addressing severe myelopathy. This novel navigation technique yields excellent outcomes for patients with BI.

RESUMO

PURPOSE: The prevalence of metastatic epidural spinal cord compression (MESCC) is increasing globally due to advancements in cancer diagnosis and treatment. Whilst surgery can benefit specific patients, the complication rate can reach up to 34%, with limited reporting on their impact in the literature. This study aims to analyse the influence of major complications on the survival of surgically treated MESCC patients. METHODS: Consecutive MESCC patients undergoing surgery and meeting inclusion criteria were selected. Survival duration from decompressive surgery to death was recorded. Perioperative factors influencing survival were documented and analysed. Kaplan-Meier survival analysis at one year compared these factors. Univariate and multivariate Cox proportional hazard regression analyses were performed. Additionally, univariate analysis compared complicated and uncomplicated groups. RESULTS: Seventy-five patients were analysed. Median survival for this cohort was 229 days (95% CI 174-365). Surgical complications, low patient performance, and rapid primary tumour growth were significant perioperative variables for survival in multivariate analyses (p < 0.001, p = 0.003, and p = 0.02, respectively) with a hazard ratio of 3.2, 3.6, and 2.1, respectively. Univariate analysis showed no variables associated with complication occurrence. CONCLUSION: In this cohort, major surgical complications, patient performance, and primary tumour growth rate were found to be independent factors affecting one year survival. Thus, prioritizing complication prevention and appropriate patient selection is crucial for optimizing survival in this population.

RESUMO

INTRODUCTION: Rosai-Dorfman disease (RDD) is a rare non-Langerhans cell histiocytosis involving the central nervous system in 5% of cases. Spinal location occurs in less than 1% of extranodal RDD and can be responsible for neurological manifestations. We present a systematic review of cases of isolated spinal RDD. We also report a new case of isolated spinal RDD revealed by spinal cord compression. MATERIALS AND METHODS: The systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline using the MEDLINE and SCOPUS databases and included case reports and case series describing isolated RDD of the spine. RESULTS: There were 53 patients with isolated spinal RDD (including our case). The mean age was 35.85±16.48 years. Neurological deficit was the most frequent clinical presentation (89%). RDD lesions were mainly located in the thoracic spine (51%), then the cervical spine (32%). The lesion was reported to be extradural (57%), intradural extramedullary (26%), intramedullary (7%), and in the vertebral body (10%). Histological examination showed emperipolesis in 73%. Histocytes were positive for S-100 protein in 83%. Treatment was based on surgery 96%), radiotherapy, chemotherapy, and adjunctive steroid therapy were indicated in four, one, and eight cases. After a mean follow-up period of 14.84±13.00 months, recurrence of RDD was noted in 15%. CONCLUSION: Spinal RDD is a rare condition, requiring meticulous histological examination for accurate diagnosis. Complete surgical resection is the treatment of choice. Adjuvant chemotherapy and radiotherapy can also be indicated in patients demonstrating partial improvement following surgery.

RESUMO

BACKGROUND: Skeletal-related events (SREs), including the pathological fracture, surgical treatment or radiation of bone lesions, malignant spinal cord compression, hypercalcemia, are important considerations when managing metastatic bone tumors; however, owing to their rarity, the incidence of SREs in patients with Ewing sarcoma remains unknown. METHODS: We retrospectively reviewed the clinical data from 146 patients with Ewing sarcoma treated at a single institution from 2005 to 2019. The median age at diagnosis was 22.7 years. Fifty patients (34.2%) had metastatic disease at diagnosis. The primary outcome was the SRE-free rate among patients with Ewing sarcoma. Moreover, we identified the risk factors for SREs using univariate or multivariate analyses. RESULTS: During the observational period (median, 2.6 years), SREs occurred in 23 patients. Radiation to the bone, malignant spinal cord compression, and hypercalcemia were documented as the initial SREs in 12 patients (52.2%), 10 patients (43.5%), and one patient (4.3%), respectively. The SRE-free rate was 94.2 ± 2.0, 87.3 ± 3.0, and 79.6 ± 3.8% at 1, 2, and 3 years after the initial visit, respectively. Multivariate analysis revealed bone metastasis at diagnosis (hazard ratio [HR] = 4.41, p = 0.007), bone marrow invasion (HR = 34.08, p < 0.001), and local progression or recurrence after definitive treatment (HR = 3.98, p = 0.012) as independent risk factors for SREs. CONCLUSIONS: SREs are non-rare events that can occur during the treatment course for Ewing sarcoma, with an especially high incidence of malignant spinal cord compression. Patients with metastatic disease at diagnosis, especially in the bone or bone marrow, or with local progression or recurrence after definitive treatment, should be carefully monitored for the occurrence of SREs. The most effective methods to monitor the occurrence of SREs and new preventative therapies for SREs should be investigated in the future.

RESUMO

BACKGROUND: Capillary hemangiomas are rare vascular lesions that rarely affect the central nervous system. When they present within the spinal canal, they are typically confined intradurally, with intramedullary extension rare. We present a rare case of spinal intramedullary capillary hemangioma, with a systematic review of the literature. METHODS: Medical records and imaging data were retrospectively reviewed using the health record software EPIC (Verona, Wisconsin, USA) and the radiology management software system RIS/PACS (Radiology Information System/Picture Archiving and Communication System; QREADS). The report was written in accordance with the CARE (case reports) guidelines. We also performed a systematic review of the literature on all cases of intramedullary spinal capillary hemangiomas in accordance with PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. RESULTS: We report a case of a 54-year-old man who presented with progressive paraplegia and sensory deficits in the lower extremities. Spinal magnetic resonance imaging showed an intramedullary enhancing lesion centered at T11 with associated spinal cord compression. He underwent thoracic laminectomy and gross total resection of the lesion without complications and subsequent improvement on his neurological examination. Histological examination showed findings consistent with a capillary hemangioma. The literature review also documented 21 studies with a combined total of 38 cases of intramedullary spinal capillary hemangioma. CONCLUSIONS: Purely intramedullary capillary hemangiomas are unusual spinal lesions with only a few cases reported in the literature. These should be considered in the differential diagnosis of intramedullary tumors. Surgical management remains the first line of treatment for symptomatic patients.

RESUMO

Radiation therapy plays a fundamental role in oncological emergencies such as superior vena cava syndrome (SVCS) and metastatic epidural spinal cord compression (MESCC). These are two examples of critical complications of metastatic cancer in terms of pain and functional impact (respiratory and/or neurological). The aim of this review is to explore the current indications, treatment options and outcomes for emergency radiotherapy regarding to these complications.Regarding SVCS, studies are mostly retrospective and unanimously demonstrated a beneficial effect of radiotherapy on symptom relief. Spinal cord compression remains an indication for urgent radiotherapy, and should be combined with surgery when possible. The innovative stereotactic body radiotherapy (SBRT) showed promising results, however this technique requires small volumes and more time preparation and therefore is often unsuitable for SVCS and MESCC emergencies.This review concluded that radiotherapy has a central role to play within a multimodal approach for SVCS and MESCC treatment. Further prospective studies are needed to confirm the effectiveness of radiation and establish the criteria for selecting patients to benefit from this treatment option.

RESUMO

The development and diffusion of minimally invasive (MI) approaches have coincided with improvements in magnification systems. The exoscope will probably open a new era in new technologies in spinal surgery. This study reports a retrospective series of 19 thoracolumbar (T11-L2) burst fractures with anterior column failure and cord compression, treated with MI corpectomy and spinal decompression assisted by a three-dimensional high-definition exoscope (Video 1). Exclusion criteria were pathologic or osteoporotic fractures, multilevel fractures, and previous surgery at the site of the fracture. Three key indicators were recorded: surgical time, blood loss, and intraoperative complications. A questionnaire was administered to assess the users' exoscope experience with ergonomics, preparation, magnification, image definition, illumination, and user-friendliness, compared with the operative microscope. To the best of our knowledge, this is the first study reporting on exoscope-assisted MI corpectomy. This procedure permitted low blood loss and less surgical time without intraoperative complications. The exoscope offers clear advantages in terms of ergonomics, definition, and user-friendliness. Moreover, it is a suitable instrument for training and education, providing an opportunity for better interaction with other members of the surgical staff.

RESUMO

A 3 yr old spayed female Cavalier King Charles spaniel was referred for insidious ataxia and paraparesis. A thoracolumbar lesion was suspected. Computed tomography showed focal osteolysis of the vertebral body and pedicles of T5. In addition, a hyperdense, extradural material within the vertebral canal, causing spinal cord compression on the right side, was present. The lesion was confirmed with magnetic resonance imaging. A T4-T5 hemi-dorsal laminectomy was performed to decompress the spinal cord. Histopathological examination was consistent with vertebral angiomatosis. After the surgery, the dog rapidly improved; however, 5 mo later the clinical signs relapsed. Vertebral angiomatosis is a vasoproliferative disorder, rarely reported as a cause of myelopathy in cats. This condition has not previously been reported in dogs. This case report describes the clinical features, the diagnostic findings, and the follow-up of a young dog with vertebral angiomatosis.

RESUMO

CASE: An 85-year-old woman was transported to our institution due to difficulty in walking. Preoperative imaging showed spinal cord lesions indicative of spinal cord tumor at the T7-8 level, accompanied by T8 vertebral fracture. Intraoperatively, the spinal lesion was suspected to be an epidural abscess; therefore, the capsule was resected, and the abscess was drained. We added pedicle screw fixation at the T6-10 level. Postoperatively, the spinal cord lesion was definitively diagnosed as spinal epidural tuberculoma. CONCLUSION: Spinal epidural tuberculomas should be considered in the treatment of spinal cord lesions causing paralysis attributed to spinal cord compression.

RESUMO

Spinal cord schistosomiasis is a rare and severe form of schistosomiasis. The prognosis is largely conditioned by early diagnosis and treatment. The authors present a case of spinal cord schistosomiasis complicated by spinal cord compression syndrome. This is the case of a 6-year-old patient who presented with febrile gastroenteritis followed by complete paralysis of both lower limbs of sudden onset following a brief stay in a village setting with notion of multiple baths at a stream. Spinal cord MRI revealed an enlarged spinal cord spanning D10 to D12 with heterogeneous contrast enhancement and a syrinx cavity above the lesion. Biological workup revealed an inflammatory syndrome. Treatment consisted of decompressive laminectomy with biopsy of the lesion and a syringo-subarachnoid shunt. Pathological analysis revealed fragments of central nervous system tissues with an infiltrate composed of lymphocytes, plasmocytes, and macrophages producing granulomatous foci lined with areas of necrosis in addition to a large contingent of polynuclear eosinophils, agglutinating around or covering in some places elongated ovoid structures, with relatively thick eosinophilic shells and presenting a terminal spur. Adjuvant treatment consisted of praziquantel and corticotherapy for 1 month. The evolution showed marked improvement in the neurological deficits. She now walks unassisted and has good sphincter control. Spinal cord schistosomiasis is rare in our context; its diagnosis is difficult. The treatment is both medical and surgical.

RESUMO

BACKGROUND: Metastatic epidural spinal cord compression (MESCC) and pathological vertebral compression fractures (pVCF) are the most serious debilitating morbidities of spine metastases (SpMs) causing devastating neurological damages. The respective impact of these two metastasis-spreading entities on survival and on neurological damage is debated. METHODS: A French prospective cohort study collected 279 consecutive patients presenting with SpMs between January 2017 and 2021. We compared 174 patients with MESCC and 105 patients with pVCF. RESULTS: The median Overall Survival (OS) for the MESCC group was 13.4 months (SD 1.5) vs 19.2 months (SD 2.3) for pVCF patients (p = 0.085). Sixty-five patients (23.3 %) were operated on: 49/65 (75.4 %) in the MESCC group and 16/65 (15.2 %) in the pVCF group, p < 0.0001. At 6 months FU, in the MESCC group, 21/44 (45.4 %) of non-ambulatory patients at onset improved to ambulatory status (Frankel D-E) vs 10/13 (76.9 %) in the pVCF group (p = 0.007). In multivariable analysis with the Cox proportional hazard model, good ECOG-PS and SINS Score 7-12 [HR: 6.755, 95 % CI 2.40-19.00; p = 0.001] were good prognostic factors for preserved ambulatory neurological status. However, SpMs diagnosed synchronously with the primary tumor [HR: 0.397, 95 % CI 0.185-0.853; p = 0.018] and MESCC [HR: 0.058, 95 % CI 0.107-0.456; p = 0.007] were independent risk factors for impaired neurological function. CONCLUSION: Contrary to pVCF, MESCC causes neurological damage. Nevertheless, neurological recovery remains possible. MESCC and pVCF have no impact on survival. The management of MESCC remains to be clarified and optimized to reduce neurological damage.

RESUMO

OBJECTIVE: To analyze preoperative predictors of ambulatory recovery after surgical treatment in metastatic spinal cord compression (MSCC) patients with delayed surgical timing and progressive paraplegia. METHODS: We reviewed patients with a preoperative lower-extremity motor grade of ≤3 and surgical timing ≥48 hours after the nonambulatory status. The recovery group (group R) and nonrecovery group (group NR) were classified according to ambulation assessment during follow-up. The data on patient demographics, origin of the primary tumor, pre and postoperative chemotherapy and radiation therapy, surgical procedures, Tokuhashi score, Karnofsky score, preoperative lower-extremity motor grade, and surgical timing were collected for analyzing predictors of postoperative ambulatory recovery. RESULTS: Of the 55 patients, 24 (43.6%) were group R and 31 patients were group NR. The preoperative motor grade of the lower extremities was the only predictive factor (P < 0.05). The mean hip flexor and knee extensor motor grades in group R were 2.0 ± 1.0 and 2.4 ± 1.1 respectively, while in group NR, they were 1.2 ± 1.0 and 1.3 ± 1.0. The odds ratios for failing to regain ambulatory ability were 12.6 in the knee extensor and 4.8 in the hip flexor when the motor grades 0-2 and 3 groups were compared. The rescue ratio of the preoperative hip flexor and knee extensor motor grade 0-2 group were 34.1% and 21.2%, grades 3 group were 71.4% and 77.3%, respectively. CONCLUSIONS: The significant predictive factor for ambulatory recovery was the preoperative lower-extremity motor grade. The preoperative knee extensor motor grade was identified as a more important factor than hip flexor motor grade in predicting ambulatory recovery.

BACKGROUND CONTEXT: Degenerative cervical myelopathy (DCM) is a form of acquired spinal cord compression and contributes to reduced quality of life secondary to neurological dysfunction and pain. There remains uncertainty regarding optimal management for individuals with mild myelopathy. Specifically, owing to lacking long-term natural history studies in this population, we do not know whether these individuals should be treated with initial surgery or observation. PURPOSE: We sought to perform a cost-utility analysis to examine early surgery for mild degenerative cervical myelopathy from the healthcare payer perspective. STUDY DESIGN/SETTING: We utilized data from the prospective observational cohorts included in the Cervical Spondylotic Myelopathy AO Spine International and North America studies to determine health related quality of life estimates and clinical myelopathy outcomes. PATIENT SAMPLE: We recruited all patients that underwent surgery for DCM enrolled in the Cervical Spondylotic Myelopathy AO Spine International and North America studies between December 2005 and January 2011. OUTCOME MEASURES: Clinical assessment measures were obtained using the Modified Japanese Orthopedic Association scale and health-related quality of life measures were obtained using the Short Form-6D utility score at baseline (preoperative), 6 months, 12 months and 24 months postsurgery. Cost measures inflated to January 2015 values were obtained using pooled estimates from the hospital payer perspective for surgical patients. METHODS: We employed a Markov state transition model with Monte Carlo microsimulation using a lifetime horizon to obtain an incremental cost utility ratio associated with early surgery for mild myelopathy. Parameter uncertainty was assessed through deterministic means using one-way and two-way sensitivity analyses and probabilistically using parameter estimate distributions with microsimulation (10,000 trials). Costs and utilities were discounted at 3% per annum. RESULTS: Initial surgery for mild degenerative cervical myelopathy was associated with an incremental lifetime increase of 1.26 quality-adjusted life years (QALY) compared to observation. The associated cost incurred to the healthcare payer over a lifetime horizon was $12,894.56, resulting in a lifetime incremental cost-utility ratio of $10,250.71/QALY. Utilizing a willingness to pay threshold in keeping with the World Health Organization definition of "very cost-effective" ($54,000 CDN), the probabilistic sensitivity analysis demonstrated that 100% of cases were cost-effective. CONCLUSIONS: Surgery compared to initial observation for mild degenerative cervical myelopathy was cost-effective from the Canadian healthcare payer perspective and was associated with lifetime gains in health-related quality of life.

RESUMO

Vertebral bodies are one of the most common metastasis sites found in advanced prostate cancer and have a significant impact on patients' quality of life. Spinal metastases frequently cause severe back pain and in some occasions can lead to secondary complications, with serious neurological deficits and loss of function. The main treatment goals include adequate pain management, controlling tumour growth and restoring spinal stability. Publications on the role of surgery - both conventional and stereotactic radiotherapy, and either as an individual modality or in combination - have been inconclusive. The NOMS score has proven to be useful in making treatment decisions. Existing data show better outcomes in patients with surgical therapy, both when performed in isolation and also combined with radiotherapy, in which some of the cohorts studied including patients with primary cancer other than prostate cancer. Comparative studies that specifically investigate the superiority of specific therapy modalities for metastatic prostate carcinoma are scarce. Similarly, there are limited data on microsurgical interventions for spinal metastases. Radiotherapy alone is crucial in the setting of palliation, especially for pain relief, and its effectiveness has been shown in many studies. The patient's life expectancy plays a crucial role in deciding the most appropriate treatment approach. Given the complexity of the patient population, a multimodal therapy approach is necessary. Current trends in therapy favour greater use of surgical interventions, particularly in the early detection of spinal metastases.
