ABSTRACT

Background:
The Paranormal and Supernatural Beliefs Scale (PSBS) was developed to assess paranormal and supernatural beliefs in the population. The scale is of particular interest to Indians as these beliefs abound in India. However, India faced a language barrier because it was only available in English.

Aim:
To evaluate the validity and reliability of the Bengali translation of the PSBS.

Materials and Methods:
Two linguistic experts well-versed in English and Bengali languages independently prepared two Bengali translations of the PSBS, giving the first two versions of the Bengali scale. The subject experts by consensus prepared version 3 of the scale. Two other bilingual experts back-translated version 3 of the PSBS into the English language resulting in the fourth version. Subject experts addressed differences between the fourth version of the English scale and the original version. Then version 4 was once again translated to Bengali, leading to the fifth version of the scale, which was administered to 30 individuals, who were asked to critique the items. Their suggestions were incorporated, to arrive at the sixth and final version of the Bengali translation. By convenience sampling, 91 volunteers conversant in both the English and Bengali languages were included. The subjects were administered alternately the original English version or the Bengali version of the scale initially. Then after a gap of 14 days, those who initially received the English version filled up the Bengali translation, while those who received the Bengali version filled up the English version of the scale.

Results:
The original English scale and the Bengali version had a mean (SD) score of 13.97 (±6.84) and 13.78 (±6.76), respectively. The scores were significantly positively correlated (Spearman’s rho = 0.900; P < 0.001). The translated scale showed a high degree of internal consistency and acceptable split-half reliability. A principal component analysis with varimax rotation yielded a one-factor solution. The Bengali translation of the PSBS was easily comprehended by the participants. Results of the Rasch analysis showed the scale had good infit and outfit values. The person’s reliability was good. The Wright map showed a good distribution of the items.

Conclusion:
The Bengali translation of PSBS is a valid and reliable tool to gauge the supernatural and paranormal beliefs of the Bengali-speaking population of India.

Background:
Anterior cervical discectomy and fusion (ACDF) is a common surgery for patients with degenerative cervical disease and current interbody spacers utilized vary based on material composition, structure, and angle of lordosis. Currently, there is a lack of literature comparing subsidence rates or long-term radiographic outcomes with hyperlordotic and standard lordotic spacers. This study compares long-term radiographic outcomes, subsidence rate, and rate of fusion in patients who underwent ACDF with hyperlordotic or standard interbody placement.

Materials and Methods:
Patients who underwent 1–3-level ACDF with either a standard lordosis or hyperlordotic interbody were included. Standard radiographs were evaluated for C2–7 lordosis (CL), sagittal vertical axis, C2 slope (C2S), T1 slope (T1S), subsidence rate, and fusion.

Results:
Forty-five patients underwent ACDF with hyperlordotic interbody placement and after a 1:1 propensity match with standard lordotic patients, 90 patients were included. 1-year postoperative radiographs demonstrated the hyperlordotic cohort achieved higher CL (15.3° ± 10.6° vs. 9.58° ± 8.88°; P = 0.007). The change in CL (8.42° ± 9.42° vs. 0.94° ± 8.67°; P < 0.001), change in C2S (−4.02° ± 6.68° vs. −1.11° ± 5.42°; P = 0.026), and change in T1S (3.49° ± 7.30° vs. 0.04° ± 6.86°, P = 0.008) between pre- and postoperative imaging were larger in the hyperlordotic cohort. There was no difference in overall subsidence (P = 0.183) and rate of fusion (P = 0.353) between the cohorts.

Conclusion:
Hyperlordotic spacer placement in ACDF can provide increased CL compared to standard lordosis spacers, which can be considered for patients requiring restoration or maintenance of CL following ACDF.
The effectiveness of posterior Schanz screw system in the anatomical restoration of thoracolumbar vertebral burst fractures: A 10-year single-institution experience
Authors: Giorgi Pietro Domenico , Legrenzi Simona , Youchen Ye , Federico Bove , Schirò Giuseppe Rosario 
Published: January 2025

Introduction:
The Schanz screw system was developed for manual reduction of traumatic sagittal deformity of thoracic and lumbar vertebral fracture. The aim of this study was to evaluate clinical and radiological effectiveness of this system in the surgical treatment of thoracolumbar burst fractures (TLBFs) with severe kyphotic deformity without neurological deficit.

Materials and Methods:
A retrospective analysis was conducted on 101 patients who underwent short posterior fixation with transpedicular Schanz screws between 2012 and 2022 for single-level (T12 or L1) TLBFs. Clinical outcomes (Oswestry Disability Index [ODI] and Visual Analog Scale [VAS]) and radiological parameters (sagittal alignment and spinal canal dimensions) were assessed with a minimum 2-year follow-up.

Results:
A total of 101 TLBFs patients with an average age of 48.1 years (range: 26–65) were included in this study. Intraoperative reduction of the Sagittal Kyphosis (SK) achieved an average of 12.31° ± 8.1°°, with a mean sagittal index (SI) correction of 15.23° ± 4.24°. At a minimum 2-year follow-up, the total amount of kyphosis reduction was maintained, with no significant difference between immediate postoperative and early follow-up measurements. Load-sharing score >8, body mass index >26, preoperative radiological parameters (SI, SK, and anterior body height [ABH] ratio), and postoperative ABH ratio were identified as significant predictors of correction loss >10°. At the final follow-up, all patients had minimal disability, with an average ODI of 7.9%. VAS scores also showed significant improvement, indicating substantial clinical effectiveness of the Schanz screw system in managing these complex spinal injuries.

Discussion:
The Schanz screw system proved to be an effective and reliable method for treating TLBFs with severe kyphosis. The system’s ability to achieve and maintain deformity reduction, coupled with favorable clinical outcomes, supported its use in the surgical management of these challenging spinal injuries.

Conclusion:
The Schanz screw system offered a viable treatment option for severe kyphotic deformity in TLBFs.

Published: January 2025

Introduction:
There is a paucity of information or guidelines regarding return to sports activities after posterior scoliosis surgery for adolescent idiopathic scoliosis (AIS).

Research Question:
Review the rate of return to sports and correlation to Lenke type following surgery for AIS in a tertiary center for pediatric spinal deformity.

Materials and Methods:
Ninety patients were identified to have undergone surgery for AIS from 2016 to 2017 and were sent a return to sport questionnaire. Sixty-six responses were received and analyzed. For comparison, Lenke classification was divided into Subgroup 1 (Lenke type 1 and 2), Subgroup 2 (Lenke type 3 and 4), and Subgroup 3 (Lenke type 5 and 6).

Results:
The average age at the time of surgery was 14.81 (11–18) years. There were Lenke 1 (31), Lenke 2 (7), Lenke 3 (12), Lenke 4 (8), Lenke 5 (7), and Lenke 6 (1). The average number of levels fused was 10.27 (7–16). 89.3% of patients returned to school between 1 and 3 months. 19.6% of patients returned to physical education (PE) within 7–12 months, while 31.8% returned to running within 4–6 months. 7.5% of patients did not do PE and 18.2% never ran after surgery. 63.6% of patients returned to contact sports after surgery, majority within 7–12 months. 91% of patients felt that they were able to achieve their preoperative performance level. Comparing the subgroups, 92% of Subgroup 1 returned to school within 2 months, while majority of them returned to PE and running within 6 months. 60% of them returned to the same level of contact/noncontact sports level prior to surgery and 40% within 6 months. Patients in Subgroup 2 and 3 returned later to school. Patients in Subgroup 2 and 3 returned later to school, PE and running with less patients returning to contact/noncontact sports.

Conclusion:
This study was able to identify Lenke classification as an important predictor of patients returning to school, PE, and running earlier along with return to preoperative levels of contact/noncontact sports.
Perioperative complications following spinal fusion in idiopathic scoliosis: A review of 825 cases from the German Spine Registry (DWG-register) – Perioperative complications in idiopathic scoliosis
Authors: Vinas-Rios Juan Manuel , Heck Vincent J. , Medina-Govea Fatima Azucena , Islas-Aguilar Mario Alberto , Kernich Nikolaus 
Published: January 2025

Background:
Overview of the literature: Idiopathic scoliosis (IS) is most commonly developed during adolescence and affects 2%–3% of the population. The overall complication rate for corrective surgeries in adolescent IS patients is described as 6.3%. Perioperative complications include intraoperative blood loss, neurological deficit, and infection, with excessive blood loss being one of the most common. The aim of the study is to evaluate the prevalence of major and minor complications following posterior or anterior fusion for IS.

Methods:
Retrospective multicenter study of data from the DWG-Register of patients who underwent operative treatment for IS from January 2017 to September 2022. Inclusion criteria: IS, age between 10 and 30 years.

Results:
In total, 825 IS patients undergoing fusion were identified in the registry; n = 801 (Group 1) did not have operative complications and n = 24 had a complication related to surgical procedure (Group 2); therefore, the complications rate was 2.9%. A 1.3% rate of major complications and 1.6% rate of minor complications were recorded as follows: spinal cord damage n = 2 (8.4%), subfaszial hematoma n = 2 (8.4%), motor dysfunction n = 1 (4.2%), cerebrospinal fluid (CSF)-leakage n = 7 (29.2%), sensory dysfunction n = 6 (25%), bowel/bladder dysfunction n = 1 (4.2%), superficial site infection n = 2 (8.4%), and pulmonary lung atelectasis n = 3 (12.5%). According to the logistic regression model, an odds ratio for pedicel screws versus laminar hooks for hyperkyphosis correction of 3.73 and for Ponte-osteotomy of 11.5 was found.

Conclusions:
In IS patients treated operatively, the prevalence of nonneurologic postoperative complications following corrective surgery was 1.80% with CSF leak being the leading risk of complication at 0.84.%. These findings should guide surgeons in their intraoperative Dural tear repair particularly osteotomies. Alternate level pedicle-screw placement with laminar hooks leads to higher operation time and more extensive fusion with consequent slightly prevalence in perioperative complications.
Incidence and long-term patient reported outcome measures of patients with radiological cauda equina compression but without clinical features of cauda equina syndrome
Authors: Soleiman Hamzah Alsheikh , Solou Mary , Demetriades Andreas K. 
Published: January 2025

Background:
Cauda equina syndrome (CES) is a rare spinal emergency. Paradoxically, in the British NHS, suspected CES requiring an emergency magnetic resonance imaging constitutes one of the commonest reasons for acute referrals to neurosurgery/spine surgery. Further acute referrals also occur with the reverse scenario, when radiological evidence of cauda equina compression is not accompanied by the clinical red flags of the syndrome. The understanding of CES, particularly in cases with radiological compression but lacking clinical symptoms, remains limited. This study aims to explore the incidence and the long-term outcomes of such patients, addressing a significant knowledge gap.

Methods:
A single-center, retrospective and cohort study was conducted, analyzing suspected CES referrals managed between August 2013 and November 2014. Patients with radiological cauda equina compression but without clinical CES features were identified. A structured questionnaire assessed long-term patient reported outcomes.

Results:
Out of 344 suspected CES referrals, 38 patients (11%) had radiological CES of degenerative cause without clinical symptoms. From those with radiological cauda equina compression but no features of CES, 14 were assessed for long-term results and the majority still underwent surgery (64%), either emergent (35.7%) or elective (28.6%). The long-term patient reported outcomes of the operated patients revealed that 66.7% were fully ambulant, 77.8% maintained an intact sexual function, and 88.9% were free of urinary symptoms. However, no matter the management, chronic pain persisted in 85.7%.

Conclusion:
This study highlights the existence of patients who are referred urgently with radiological cauda equina compression but who lack clinical CES symptoms. Despite surgical interventions, chronic pain remains a significant issue. Further research, including multi-centered studies, is warranted to enhance our understanding of this condition and its nuanced subpopulations.

Objectives:
Anterior spinal fusion (ASF) presents unique challenges, including the proximity of critical anatomic structures. Previous reports have detailed vascular injuries during exposure/approach; however, it is not well-documented whether structural aortic pathology, such as aneurysm, dissection, atherosclerosis, aortitis, or aortic tumors, impacts postoperative outcomes following anterior approach to the spine for spinal fusion.

Materials and Methods:
Using the New York State Statewide Planning and Research Cooperative System, thoracolumbar ASF patients with a history of aneurysm, dissection, atherosclerosis, aortitis, or aortic tumors (APath) were identified and matched to patients with no aortic pathologies (No-APath). The two cohorts were compared at 90-day and 2-year follow-up for complications, readmissions, and revisions. Multivariate binary stepwise logistic regression identified independent predictors of these outcomes.

Results:
Ninety-nine and 64 patients were included at 90-day and 2-year follow-ups, respectively. APath and No-APath had comparable demographics. Through 90-day follow-up, both cohorts had similar vascular complications and overall complications. No-APath patients had higher surgical complications (11.1% vs. 0%, P = 0.021). At 2-year follow-up, cohorts had comparable vascular complications, overall complications, and all other outcomes (P > 0.05). Neither group was observed to require any revisions through 2-year follow-up. The presence of a structural aortic pathology was not associated with increased odds of incurring adverse outcomes at 90-day and 2-year follow-ups.

Conclusions:
Structural aortic compromise in the setting of thoracolumbar ASF did not predispose patients to adverse vascular, spinal-related, or medical/surgical complications, nor to anterior spinal or vascular revision or repair through 2-year follow-up. These results highlight the need for well-powered studies to further delineate the risk of anterior spinal surgery in this cohort of patients.

Authors: Piovesan Eduardo Cattapan , Silva Werner Petry , Guiroy Alfredo , De Freitas Bruna Zanatta , Vargas Vinícius Cercena , Carazzo Charles 
Published: January 2025

Background:
Bibliometric analyses are a proficient method for understanding the dynamics of publications. Unstable thoracolumbar injuries are a prevalent topic in neurosurgery and orthopedic research.

Methodology:
Web of Science was searched for the 100 most-cited articles on unstable thoracolumbar injuries. A number of citations, article title, first author’s name, year and journal of publication and its impact factor (IF), specialty, affiliation, country of the first author, and type of the article were retrieved.

Results:
The articles were published in 32 different journals from 1977 to 2020. Spine (38 articles in the top 100 and 3694 citations) was the journal with the greatest number of articles and citations, and the highest number of primary research papers (31 articles, accounting for 2915 citations). The United States was the country with the most articles (45) and citations (4541). The University of California (5 articles, 6 primary research, and 781 citations) was the institution with the highest number of citations, articles, and primary research articles. Orthopedic was the specialty with the most significant number of publications and the most cited (77 articles and 7197 citations). The first author with the greatest number of publications and primary research articles was R. F. McLain (4 articles, being 3 primary research, and 646 citations), while the most cited was A. R. Vaccaro (3 articles and 695 citations). Eighty publications were primary and 20 were secondary research.

Conclusions:
The unstable thoracolumbar research field is prominent in North America and has been more frequently published in orthopedic journals, after 1995.
Efficacy of distal peripheral nerve blocks in lumbar radicular pain: A randomized placebo-controlled triple-blinded study
Authors: Jha Vivek , Sharma Gaurav Kumar , Singh Omeshwar , Aggarwal Jatin 
Published: January 2025

Context:
Inflamed nerve root leads to mechano-sensitization and upregulation of sodium channels in nerve endings far distal to the site of inflammation, leading to tenderness of these nerve endings. Due to pseudounipolar nature, the blockade of sodium channels at peripheral nerve endings leads to relief in radicular pain.

Aims:
The aim of this study was to assess the efficacy of bupivacaine in improving pain and straight leg raising test (SLRT), 30 min after injection around tender nerves near the ankle, in patients with unilateral radicular pain.

Design:
This was a randomized placebo-controlled triple-blinded study.

Methods:
One hundred patients of single-level lumbar disc prolapse and unilateral radicular pain were randomized into two equal groups. Three nerves (sural nerve, lateral branch of deep peroneal nerve and posterior tibial nerve) were assessed for tenderness around the ankle. Bupivacaine (0.5%) was injected around each tender nerve in the case group whereas equal volume of normal saline was injected in the control group around each tender nerve. Pain Numerical Rating Scale (NRS) and SLRT were checked before and 30 min postinjection. A proportion of patients achieving minimum clinically important difference (MCID) of NRS ≤4 and MCID of SLRT ≥30° were compared.

Results:
A mean decrease in NRS among cases was from 8.06 ± 1.236 to 3.90 ± 2.013 (P < 0.001) with 78% achieving MCID. A mean decrease in NRS in the control group was from 7.88 ± 1.023 to 7.66 ± 1.171 (P = 0.084), and only 2% of patients achieved MCID. There was a statistically significant improvement in SLR in the case group (40.90°–60.90°, P < 0.001), and 54% showed a clinically significant improvement by crossing MCID threshold. The control group showed nonsignificant improvement in SLRT (38.10°–39.10°, P = 0.351), and only 2% achieved MCID.

Conclusions:
In single-level lumbar disc prolapse with unilateral radicular pain, injection of bupivacaine 0.5% (a sodium channel blocker) around tender nerves near the ankle provides clinically significant relief in pain and SLRT at 30 min when compared to placebo.
Piora dos sintomas de enxaqueca em estudantes que utilizam métodos contraceptivos na instituição de ensino IMEPAC - ARAGUARI
Authors: Carvalho Fernanda Alves , Vieira Débora , Silva Carlos Henrique de Sousa Ribeiro da 
Published: January 2025

A enxaqueca é uma doença neurovascular caracterizada por sintomas de cefaleia intensa unilateral com fonofobia e fotofobia afetando cerca de 15,8% das pessoas no Brasil onde em sua maioria são mulheres. O uso de anticoncepcionais orais combinados pode aumentar o risco de AVC e gera-se risco de aumentar as crises de enxaqueca. Como hipótese estuda-se o uso de métodos contraceptivos orais combinados pioram os sintomas de enxaqueca em maior frequência e intensidade quando comparados às pessoas que utilizam outros métodos contraceptivos ou não utilizam. Nos resultados e discussão podemos perceber que o uso de AOC não tem forte relação com o surgimento de cefaleia, mas que os sintomas da mesma podem ser piorados com o uso de AOC percebendo uma correlação entre os dados principalmente na população jovem e que demonstra alta taxa de transtornos de saúde mental em conjunto, mas vale ressaltar que os dados não encontraram validade estatística. Pode-se concluir a importância de futuras pesquisas sobre o tema para ampliar os dados sobre para a população geral e a importância do tratamento e uso de anticoncepcionais de acordo com a individualidade de cada paciente.
