RESUMO

Background: The use of bicycle helmets in preventing traumatic brain injuries (TBI) is frequently cited but data remain inconclusive. Additionally, the effects of helmets on cervical spine injuries (CSI) are debated.Methods: We performed a retrospective review of all adult patients with bicycle crashes presenting to one level 1 trauma center in Wisconsin from 2010 to 2016. Patients were divided into two groups: helmeted and un-helmeted.Results: In total 287 patients were included; 149 un-helmeted (51.9%) and 138 helmeted (48.9%). Helmeted riders had radiographic evidence of traumatic brain injury in 20.3% of cases compared to 40.3% of un-helmeted (p < 0.001). On average, helmeted riders had a similar injury severity score of 7.80 (standard deviation (SD) = 7.18) compared with 8.25 (SD = 9.98) in the un-helmeted group (p = 0.68). CSI occurred in 16 (10.7%) un-helmeted patients compared with 15 (10.9%) helmeted patients (p = 0.707). Of the un-helmeted group, four patients (2.7%) were found to have a cervical spine fracture compared with 12 (8.7%) helmeted patients (p = 0.037).Conclusion: Helmet use demonstrated a statistically significant advantage in the prevention of traumatic brain injuries. No significant difference was found regarding the incidence of severity of cervical spine injuries. These results do not demonstrate any statistically significant benefit in the prevention of cervical spine injuries with helmet use. In contrast, helmet use was found to convey a significant protective advantage in the prevention of traumatic brain injuries compared to no helmets.

RESUMO

BACKGROUND: Odontoid fractures are common cervical spine fractures; however, significant controversy exists regarding their treatment. Risk factors for failure of conservative therapy have been identified, although no predictive risk score has been developed to aid in decision-making. METHODS: A retrospective review was conducted of all patients evaluated at a level 1 trauma center. Patients identified with type II odontoid fractures as classified by the D'Alonzo Classification system who were treated with external orthosis were included in analysis. Patients were considered to have failed conservative therapy if they were offered surgical intervention. A machine learning method (Risk-SLIM) was then utilized to create a risk stratification score based on risk factors to identify patients at high risk for requiring surgical intervention due to persistent instability. RESULTS: A total of 138 patients were identified as presenting with type II odontoid fractures that were treated conservatively; 38 patients were offered surgery for persistent instability. The Odontoid Fracture Predictive Model (OFPM) was created using a machine learning algorithm with a 5-fold cross validation area under the curve of 0.7389 (95% CI: 0.671 to 0.808). Predictive factors were found to include fracture displacement, displacement greater than 5 mm, comminution at the fracture base, and history of smoking. The probability of persistent instability was <5% with a score of 0 and 88% with a score of 5. CONCLUSIONS: The OFPM model is a unique, quick, and accurate tool to assist in clinical decision-making in patients with type II odontoid fractures. External validation is necessary to evaluate the validity of these findings.

RESUMO

Background: Lumbar decompression is a commonly performed procedure for the operative management of several degenerative lumbar spinal pathologies. Although open approaches are considered the traditional method, endoscopic techniques represent a relatively novel, less-invasive option to achieve neural element decompression. Here within, we examine if the use of endoscopic techniques decreases the risk of post operative infections. Methods: We performed a retrospective cohort analysis to directly compare patients who underwent either open or endoscopic lumbar decompression at a single institution. Rates of postoperative outcomes such as surgical site infection, hospital length of stay, estimated blood loss, and others were compared between the two treatment groups. A multivariate logistic regression model was constructed using patient comorbidities and procedural characteristics to identify the risk factors for surgical site infection. Results: 150 patients were identified as undergoing lumbar spine decompression surgeries that met inclusion criteria for the study, of whom 108 (72.0%) underwent open and 61 (28.0%) underwent endoscopic approaches. Unpaired analysis revealed positive associations between operative duration, estimated blood loss, drain placement rates. Multivariate logistic regression did not reveal an association between surgical approach (open versus endoscopic) and the development of surgical site infection. Conclusions: Surgical site infections following endoscopic lumbar spine decompression are relatively uncommon, however, after adjusting for baseline differences between patient populations, surgical approach does not independently predict the development of postoperative infection.

RESUMO

Lateral femoral cutaneous neuropathy, also known as meralgia paresthetica, is a pathology commonly encountered by neurosurgeons. Symptoms include numbness, tingling, and burning pain over the anterolateral thigh due to impingement on the lateral femoral cutaneous nerve (LFCN). Surgical treatment has traditionally involved nerve release or neurectomy. LFCN transposition is a relatively new approach that can provide excellent symptomatic relief. In this video, the authors highlight key operative techniques to ensure easy identification, adequate decompression, and transposition of the nerve. Key steps include ultrasound-guided wire localization, superficial decompression, opening of the inguinal ligament, deep decompression, and medial transposition. The video can be found here: https://stream.cadmore.media/r10.3171/2022.10.FOCVID2289.

RESUMO

BACKGROUND: Thoracolumbar burst fractures include a spectrum of treatment options ranging from conservative management to multilevel fusion with or without corpectomy. Given the variability of treatment options, consideration of radiographic outcomes with different treatment modalities should be a critical consideration in management. METHODS: A retrospective review was conducted evaluating all patients presenting with spine fractures over a 7-year period. Inclusion criteria were limited to adults with acute, traumatic burst fractures of the thoracolumbar joint levels T11-L2. Patients were categorized by nonoperative management, short-segment fusion, multilevel fusion without anterior column reconstruction, and corpectomy. Radiographic information collected included kyphotic angle (KA), Cobb angle (CA), and Gardner angle (GA). RESULTS: In total, 117 patients (70.5%) were successfully treated nonoperatively, 4 (2.4%) underwent short-segment fusion, 28 (16.9%) underwent multilevel fusion, and 12 (7.2%) underwent corpectomy. All nonoperative patients demonstrated significantly worse kyphosis at 1-year follow-up as measured by KA, CA, and GA (P < 0.001). Patients undergoing corpectomy had the largest improvement in kyphosis with an average improvement of 14.1° on KA, 8.1° on CA, and 11.0° on GA (P < 0.001, P = 0.098, and P = 0.004, respectively). In comparison, patients undergoing multilevel fusion showed an average improvement of 2.6°, 2.7°, and 3.3° of correction on GA, CA, and KA, respectively (P > 0.05). CONCLUSIONS: Nonoperative and short-segment fusion burst fracture patients demonstrated significantly worse kyphosis at 1-year follow-up. Patients undergoing corpectomy demonstrated a superior improvement in kyphotic correction compared with those undergoing multilevel fusion and short-segment fusion.

RESUMO

BACKGROUND: Primary spinal epidural abscess (SEA) is a rare but serious pathology that may result in severe neurologic injury. While certain literature has identified medical risk factors for failure of conservative therapy, no current evidence has been published regarding socioeconomic risk factors associated with failure of medical therapy. METHODS: A retrospective review was conducted of patients presenting with SEA from primary spinal infections. Patients presenting with magnetic resonance imaging evidence of SEA treated conservatively in the absence of neurologic deficits were included. Baseline clinical and socioeconomic characteristics were collected. Failure of medical management was defined as requiring surgical intervention despite maximal medical therapy due to the development of neurologic deficits or clinically significant deformity. RESULTS: A total of 150 patients were identified as presenting with magnetic resonance imaging evidence of SEAs without evidence of neurologic deficit. Of these patients, 42 required surgical intervention compared with 108 whose infection was successfully treated with medical therapy alone. Estimated average annual income was $64,746 vs $62,615 in those who successfully cleared their infection with medical management without requiring surgery, which was not statistically significant (P = 0.5). Insured patients were 5 times more likely to be successfully treated with antibiotics alone compared with uninsured patients (OR = 5.83, P = 0.008). Payer type, employment status, and incarceration status were not associated with failure of conservative therapy. CONCLUSIONS: In the treatment of primary SEA, absence of medical insurance is associated with failure of medical management. Payer status, employment status, average salary, and incarceration are not significant risk factors for failure of conservative management.

RESUMO

INTRODUCTION: Endoscopic techniques in spine surgery continue to gain popularity due to their potential for decreased blood loss and post-operative pain. However, limited studies have evaluated these techniques within the United States. Additionally, given the limited number of practitioners with experience in endoscopy, most current studies are limited by a lack of heterogeneity. METHODS: The American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) database was queried to evaluate the effect of endoscopic surgery on adverse events. Current Procedural Terminology (CPT) codes for open discectomy were compared with the relevant CPT codes for endoscopic lumbar discectomy. Baseline patient characteristics and adverse outcomes were then compared.  Results: A total of 38,497 single-level lumbar discectomies were identified and included. Of these, 175 patients undergoing endoscopic discectomy were compared with 38,322 patients undergoing open discectomy. Endoscopic discectomy demonstrated a shorter operative time of 88.6 minutes than 92.1 minutes in the open group. However, this was not significant (p=0.08). Patients in the endoscopic group demonstrated a shorter total length of stay of 0.81 days vs 1.15 days (p=0.014). Total adverse events were lower in the endoscopic group at 0.6% vs 3.4% in the open group (p=0.03). CONCLUSION:  Endoscopic discectomy demonstrated a significantly lower rate of adverse events and shorter total length of stay than open discectomy. Further research is necessary over time to evaluate larger patient populations as this technology is more rapidly incorporated.

RESUMO

Background The treatment of AOSpine A3 and A4 fractures is controversial with no consensus regarding their management in the absence of neurologic deficits. While conservative management with spinal orthosis is a reasonable treatment option, it is believed to run the risk of progressive segmental kyphosis. Methodology A retrospective chart review was conducted of all patients undergoing treatment for thoracolumbar burst fractures from T11 to L2. Patients treated with conservative management with lumbar orthosis were included. Upright radiographs at the time of presentation and the one-year follow-up were compared. Results In total, 112 patients were evaluated as being treated with thoracolumbar orthosis. Of these, 61 patients presented with A3 fractures compared with 51 who presented with A4 fractures. Of these, two patients in each group failed conservative management and required surgical intervention. At the one-year follow-up, A3 fractures demonstrated an average change in Cobb angle of 4.1 degrees compared with 6.1 degrees in A4 fractures (p = 0.021). In addition, A4 fractures demonstrated a significantly worse kyphotic angle and Gardner angle at the one-year follow-up (p = 0.05 and p = 0.026, respectively). Conclusions A3 and A4 fractures can be safely treated with orthosis with overall low rates for failure; however, A4 fractures result in significantly worse segmental kyphosis at the one-year follow-up.

RESUMO

Background Cervical laminoplasty is a surgical alternative to laminectomy and fusion for treating multi-level cervical spondylotic myelopathy. There is limited evidence evaluating readmission incidence and risk factors following cervical laminoplasty. Here, we provide a retrospective review evaluating preoperative risk for 30-day readmission following cervical laminoplasty. Methodology The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients undergoing laminoplasty as defined by Current Procedural Terminology codes 63050 and 63051. Patients were then categorized based on whether 30-day readmission occurred, and preoperative risk factors were examined. Continuous and categorical variables were analyzed using Student's t-test or Fisher's exact test. Multivariate regression analysis was performed for each variable, with p-values of <0.05 considered significant. Results In total, 3,085 patients were identified as undergoing posterior cervical laminoplasty. Of these, 2,938 patients did not require readmission, and 147 patients were readmitted, representing a 4.77% 30-day readmission rate. For all patients, sepsis (odds ratio (OR) = 5.58, p = 0.03), dialysis (OR = 3.46, p = 0.01), American Society of Anesthesiologists class >2 (OR = 1.69, p = 0.011), and hypertension (OR = 1.51, p = 0.04) were predictive of readmission. A subgroup analysis was performed for all geriatric patients (aged >65). In total, 1,353 patients were identified, of whom 76 were readmitted, demonstrating a readmission rate of 5.62%. For the elderly patients, hypertension (OR = 1.98, confidence interval (CI) = 1.04-3.75, p = 0.04) and independent status (OR = 0.39, CI = 0.21-0.74, p = 0.004) were predictive of readmission. Conclusions Assessment of predictors for readmission is important for patient education and setting appropriate clinical expectations for surgeons and providers. Preoperative hypertension, dialysis, and sepsis were risk factors for 30-day readmission following cervical laminoplasty, with functional status being a unique risk factor for elderly patients.

RESUMO

BACKGROUND: The optimal management of spinal epidural abscesses (SEA) secondary to primary spinal infections has demonstrated large variability in the literature. Although some literature suggests a high rate of neurological deterioration, others suggest failure of medical management is uncommon. OBJECTIVE: To develop a predictive model to evaluate the likelihood of failure of medical therapy in the setting of SEA. METHODS: A retrospective review was conducted of all patients presenting with SEA from primary spinal infections. Patients presenting with MRI evidence of SEA without neurological deficits were included. Failure of medical management was defined as requiring surgical intervention over 72 hours after the initiation of antibiotics. A machine learning method (Risk-Calibrated Supersparse Linear Integer Model) was used to create a risk stratification score to identify patients at high risk for requiring surgical intervention. RESULTS: In total, 159 patients were identified as presenting with MRI findings of SEA without evidence of neurological deficit. Of these patients, 50 required delayed surgery compared with 109 whose infection were successfully treated with surgical intervention. The Spinal Epidural Abscess Predictive Score was created using a machine learning model with an area under the curve of 0.8043 with calibration error of 14.7%. Factors included active malignancy, spondylodiscitis, organism identification, blood cultures, and sex. The probability of failure of medical management ranged from <5% for a score of 2 or less and >95% for a score of 7 or more. CONCLUSION: The Spinal Epidural Abscess Predictive Score model is a quick and accurate tool to assist in clinical decision-making in SEA.

RESUMO

BACKGROUND: Spinal epidural abscess (SEA) is a rare but serious pathology that may result in delayed neurologic injury despite treatment with antibiotic therapy or surgery. Given this, the development of predictive scores for risk stratification has value in clinical decision making; however, external validation is necessary to understand their generalizability and reliability. METHODS: A retrospective review was conducted of all patients presenting with SEA at a single institution. Patients were reviewed and graded according to the proposed SEA predictive score by Baum et al. Clinical failure was defined as documented laboratory or radiographic progression requiring surgical intervention, increased deformity requiring surgical intervention, or repeat surgical intervention if prior surgical intervention was undertaken as the initial treatment strategy. Brier score and receiver operating characteristic were used to calculate reliability. RESULTS: There were 224 patients presenting with primary spinal infections with associated SEA. Of these, 209 patients had no history of intravenous drug abuse. Clinical failure was demonstrated in 52 of 209 patients (24.9%). Antibiotic treatment alone compared with antibiotic therapy and surgical treatment on initial presentation was found to have a significantly greater chance of clinical failure (odds ratio = 3.0930, P = 0.01). The proposed epidural abscess prediction score did not correlate with clinical outcomes with a Brier score of 0.229 and receiver operating characteristic area under the curve of 0.5944. CONCLUSIONS: The proposed risk stratification scale for patients was not correlated with risk of clinical failure. Additionally, patients treated with antibiotics and surgical intervention on initial presentation had a significantly lower clinical failure rate.

RESUMO

Spondyloepiphyseal dysplasia congenita (SEDC) is a rare autosomal dominant skeletal dysplasia resulting in impairment of type II collagen function. Phenotypically, this results in various skeletal, ligamentous, ocular, and otologic abnormalities. Platyspondyly, scoliosis, ligamental laxity, and odontoid hypoplasia are common, resulting in myelopathy in a high number of patients due to atlantoaxial instability. Despite patients undergoing surgical fixation, complication rates such as nonunion have been reported to be high. Here within, we present two patients treated with occipitocervical fusion for atlantoaxial instability and early symptoms of progressive myelopathy. We additionally provide a detailed review of the literature to inform practitioners of the spinal manifestations and clinical considerations in SEDC.

RESUMO

OBJECTIVE: Lumbar synovial cysts (LSCs) represent a relatively rare clinical pathology that may result in radiculopathy or neurogenic claudication. Because of the potential for recurrence of these cysts, some authors advocate for segmental fusion, as opposed to decompression alone, as a way to eliminate the risk for recurrence. The objective of this study was to create a predictive score for synovial cyst recurrence following decompression without fusion. METHODS: A retrospective chart review was completed of all patients evaluated at a single center over 20 years who were found to have symptomatic LSCs requiring intervention. Only patients undergoing decompression without fusion were included in the analysis. Following this review, baseline characteristics were obtained as well as radiological information. A machine learning method (risk-calibrated supersparse linear integer model) was then used to create a risk stratification score to identify patients at high risk for symptomatic cyst recurrence requiring repeat surgical intervention. Following the creation of this model, a fivefold cross-validation was completed. RESULTS: In total, 89 patients were identified who had complete radiological information. Of these 89 patients, 11 developed cyst recurrence requiring reoperation. The Lumbar Synovial Cyst Score was then created with an area under the curve of 0.83 and calibration error of 11.0%. Factors predictive of recurrence were found to include facet inclination angle > 45°, canal stenosis > 50%, T2 joint space hyperintensity, and presence of grade I spondylolisthesis. The probability of cyst recurrence ranged from < 5% for a score of 2 or less to > 88% for a score of 7. CONCLUSIONS: The Lumbar Synovial Cyst Score model is a quick and accurate tool to assist in clinical decision-making in the treatment of LSCs.

RESUMO

Background: Thoracic outlet syndrome (TOS) is a clinical diagnosis caused by compression of neurovascular structures in the thoracic outlet. There are a variety of structures that cause compression implicated in TOS. TOS patients frequently require surgical decompression. Various structural anomalies encountered during decompression have been reported in the literature. Case Description: We present two females (ages 42 and 45) that each underwent anterior scalenectomy for thoracic outlet decompression through a supraclavicular approach. A supraclavius muscle anomaly was observed in both patients. Analogous to the two reports previously described in the literature, the muscle inserted, along the medial superior undersurface of the clavicle and originated dorsally along the trapezius muscle. This is not to be confused with the subclavius posticus muscle, which originates from the first rib and inserts on the upper border of the scapula. Conclusion: These two cases represent just the third and fourth ever descriptions of a supraclavius muscle anomaly encountered during TOS surgery. Due to the wide variety of anatomical variations encountered during TOS surgery, it is not only crucial for continued reporting of such anatomical variations to be reported in the literature but equally important for clinicians that treat TOS to be aware of such variations.

RESUMO

Background: The use of instrumentation in the setting of primary spinal infections is controversial. While the instrumentation is often required in the presence of progressive deformity due to spinal osteomyelitis (SO), discitis (SD), or spinal epidural abscesses (SEA), many surgeons are concerned about instrumentation increasing the risk of infection recurrence and/or persistence warranting reoperation. Methods: We retrospectively reviewed the need for reoperations for persistent infections in 119 patients who presented with primary spinal infections. They were treated with decompressions with/without non-instrumented fusion (70 patients) versus decompressions with instrumented fusions (49 patients). Results: The use of primary spinal instrumentation in the presence of infection (SO/SD/SEA) did not increase the requirement for repeated surgery due to recurrent/residual infection when compared to those undergoing decompressions with/without non-instrumented fusions. Of 49 patients who initially required instrumentation, 6 (12.5%) required reoperations for recurrent or residual infection. For the 71 undergoing index decompressions for infection with/without non-instrumented fusion, 9 (12.7%), or nearly an identical percentage, required reoperations for recurrent/residual infection (P = 0.93). Conclusion: The use of instrumentation in the treatment of primary spinal infections in a small sample of just 49 patients did not increase the risk for persistent infection warranting reoperations versus 70 patients undergoing initial decompressions with/without non-instrumented fusions.

RESUMO

Background: A Chance fracture is a traumatic fracture of the thoracic or lumbar spine that occurs secondary to a flexion-distraction injury. Although patients with chance fractures rarely present with neurologic deficits, a subset may become symptomatic from spinal epidural hematomas (SEH) warranting emergent decompressive surgery. Case Description: An 87-year-old female on anticoagulation presented with a T1 Chance fracture after a fall. She was originally neurologically intact, but became paraplegic over the next 10 h. When the cervical/thoracic magnetic resonance revealed a SEH markedly compressing the cord between the C7-T1 levels, she underwent an emergent decompression; she also had a C5-T4 instrumented fusion. Postoperatively, she regained lower limb function, but expired on postoperative day 5 due to respiratory complications likely attributed to the prolonged surgery for the spinal instrumentation. Conclusion: Delayed SEH rarely occur following spinal Chance fractures. Here, an 87-year-old female on anticoagulation developed the 10-h delayed onset of a SEH with paraplegia attributed to a T1 Chance fracture at the C7-T1 level. Although she regained neurological function following the emergent decompression, she expired 5 days later likely due to the extended operative time/blood loss from the C5-T4 fusion that could have been avoided.

RESUMO

Background: Internuclear ophthalmoplegia (INO), characterized by impaired horizontal eye movement, occurred following an anterior cervical discectomy/fusions (ACDF). Case Description: A 48-year-old female with recurrent C5-6 foraminal stenosis presented with right C6 radiculopathy. She underwent a C5-6 ACDF, but postoperatively, complained of diplopia. Her examination revealed left-eye INO. Notably, the brain magnetic resonance imaging showed no significant radiological findings. The patient's diplopia and INO resolved spontaneously on postoperative day 2 and never recurred. Conclusion: Ocular complications following anterior cervical spine procedures are rare. Here, a 48-year-old female developed left eye INO following an ACDF that spontaneously resolved on postoperative day 2.

RESUMO

BACKGROUND: Noonan syndrome (NS) is a rare genetic RASopathy with multisystem implications. The disorder is typically characterized by short stature, distinctive facial features, intellectual disability, developmental delay, chest deformity, and congenital heart disease. NS may be inherited or arise secondary to spontaneous mutations of genes in the Ras/mitogen activated protein kinase signaling pathways. OBSERVATIONS: Numerous case reports exist detailing the association between NS and Chiari I malformation (CM-I), although this relationship has not been fully established. Patients with NS who present with CM-I requiring operation have shown high rates reoperation for failed decompression. The authors reported two patients with NS, CM-I, and syringomyelia who had prior posterior fossa decompressions without syrinx improvement. Both patients received reoperation with successful outcomes. LESSONS: The authors highlighted the association between NS and CM-I and raised awareness that patients with these disorders may be at higher risk for failed posterior fossa decompression, necessitating reoperation.

RESUMO

Arachnoiditis is a relatively rare condition and can result in long-term chronic and debilitating complications if not diagnosed early and treated properly. However, diagnosis of arachnoiditis is rare and knowledge of potential causes of this condition is still sparse. Current known causes of arachnoiditis include infections, trauma, spinal tumors, and iatrogenic causes induced via neurological interventions. Here, we present a case of a 65-year-old female who presented with arachnoiditis caused by Candida albicans infection from a contaminated ventriculoperitoneal (VP) shunt, placed following the development of hydrocephalus from subarachnoid hemorrhage. During her initial assessment, the possibility of arachnoiditis was raised after spinal magnetic resonance imaging (MRI) due to leg weakness and spasms with bladder dysfunction. However, further workup was not pursued after a normal spinal angiogram and lack of constitutional symptoms. She presented six months later with symptoms of fever and lower abdominal pain. She was diagnosed with fungal arachnoiditis after a computerized tomography (CT) of the abdomen showed thickening of the fascia around the shunt catheter and fluid collections near the tip of the shunt in the abdominal cavity after hospitalization. The diagnosis was made after an ultrasound-guided tap of the same area revealed budding yeast and cerebrospinal fluid (CSF) showed growths of Candida albicans. Her shunt was removed, and she received intravenous (IV) antifungals and recovered. MRI should be considered with clinical presentations that are characteristic of arachnoiditis. Symptoms from fungal infections are usually dramatic; however, in some instances as in this case, they may follow a more progressive course. The patient should be extensively evaluated for infection, especially fungal, in interventions involving device placement even when minimally, but persistently, symptomatic.
