Background/aimRecent rule changes regarding the safety of basketball athletes necessitate up-to-date reports of injury incidence. This study describes the epidemiology of injuries in men's and women's National Collegiate Athletic Association (NCAA) basketball during the 2009/2010–2014/2015 seasons.MethodsBasketball injury data originate from the 2009/2010–2014/2015 academic years from the NCAA Injury Surveillance Program (NCAA-ISP) from 78 men's and 74 women's NCAA basketball programmes which provided 176 and 181 team-seasons, respectively. A reportable injury occurred during organised practice or competition and required attention from an athletic trainer (AT) or physician. Injury rates, injury proportions and rate ratios (RRs) were calculated. All 95% CIs not containing 1.0 were considered statistically significant.ResultsA total of 2308 and 1631 injuries were reported in men's and women's basketball, respectively, for injury rates of 7.97 and 6.54/1000 athlete-exposures (AEs). The rate was higher in men than women (RR=1.22; 95% CI 1.15 to 1.30). Non-time-loss (NTL) injuries (resulting in participation restriction time under 24 hours) accounted for 64.8% and 53.6% of men's competition and practice injuries, respectively, and 53.9% and 51.3% of women's competition and practice injuries, respectively. Injuries to the lower extremity were the most common in competitions (men: 54.9%; women: 59.0%) and practices (men: 62.4%; women: 67.3%). The most common injury in men's and women's basketball was ankle sprain (17.9% and 16.6%, respectively).ConclusionsNTL injuries account for over half of all injuries in basketball. Most injuries were lower extremity injuries, specifically ankle sprains. While rule changes have been implemented to make basketball safer, continued research is needed to assess the effectiveness of these changes.

Traumatic spinal injury (TSI) is a disease of significant global health burden, particularly in low and middle-income countries where road traffic-related trauma is increasing. This study compared the demographics, injury patterns, and outcomes of TSI caused by road traffic accidents (RTAs) to non-traffic related TSI. A retrospective analysis was conducted using a neurotrauma registry from the Muhimbili Orthopaedic Institute (MOI) in Tanzania, a national referral center for spinal injuries. Patient sociodemographic characteristics, injury level, and severity were compared across mechanisms of injury. Neurological improvement, neurological deterioration, and mortality were compared between those sustaining TSI through an RTA versus non-RTA, using univariable and multivariable analyses. A total of 626 patients were included, of which 302 (48%) were RTA-related. The median age was 34 years, and 532 (85%) were male. RTAs had a lower male preponderance compared to non-RTA causes (238/302, 79% vs. 294/324, 91%, p<0.001) and a higher proportion of cervical injuries (144/302, 48% vs. 122/324, 38%, p<0.001). No significant differences between RTA and non-RTA mechanisms were found in injury severity, time to admission, length of hospital stay, surgical intervention, neurological outcomes, or in-hospital mortality. Improved neurological outcomes were associated with incomplete injuries (AIS B-D), while higher mortality rates were linked to cervical injuries and complete (AIS A) injuries. Our study in urban Tanzania finds no significant differences in outcomes between spinal injuries from road traffic accidents (RTAs) and non-RTA causes, suggesting the need for equitable resource allocation in spine trauma programs. Highlighting the critical link between cervical injuries and increased mortality, our findings call for targeted interventions across all causes of traumatic spinal injuries (TSI). We advocate for a comprehensive trauma care system that merges efficient pre-hospital care, specialized treatment, and prevention measures, aiming to enhance outcomes and ensure equity in trauma care in low- and middle-income countries.

Introduction Pseudarthrosis after cervical spine surgery represents an underreported and challenging complication. Using a large multi-center surgical database, we sought to: (1) report the incidence of cervical pseudarthrosis, (2) evaluate changes in rates of cervical pseudarthrosis, and (3) describe risk factors for suboptimal outcomes after cervical pseudarthrosis surgery. Methods The American College of Surgeons National Surgical Quality Improvement Program database from 2012 to 2019 was used. The primary outcome was occurrence of a cervical fusion procedure with a prior diagnosis of pseudarthrosis. Fusion for pseudarthrosis was divided into anterior and posterior approaches. Post-operative complications were classified as major or minor. Prolonged LOS was defined as exceeding the 75th percentile for total hospital stay. Results A total of 780 patients underwent cervical fusion for pseudarthrosis, and a significant increase in rates of surgery for pseudarthrosis was seen (0.25–1.2%, p  < 0.001). The majority of cervical pseudarthrosis was treated with a posterior approach (66.5%). Postoperatively, 38 (4.9%) patients suffered a complication and 247 (31.7%) had a prolonged LOS. The three strongest risk factors for complications and extended LOS were > 10% weight loss preoperatively, congestive heart failure, and pre-operative bleeding disorder. Conclusion Results from a large multi-center national database revealed that surgery to treat cervical pseudarthrosis has increased from 2012 to 2019. Most pseudarthrosis was treated with a posterior approach. Reoperation to treat cervical pseudarthrosis carried risk, with 5% having complications and 32% having an extended LOS. These results lay the groundwork for a future prospective study to discern the true incidence of cervical pseudarthrosis and how to best avoid its occurrence.

Abstract Intraventricular access is frequently required during neurosurgery, and when neuronavigation is unavailable, the neurosurgeon must rely upon craniometrics to achieve successful ventricular cannulation. In this historical review, we summarize the most well-described ventricular access points: Kocher's, Kaufman's, Paine's, Menovksy's, Tubbs’, Keen's, Frazier's, Dandy's, and Sanchez's. Additionally, we provide multiview, 3-dimensional illustrations that provide the reader with a novel understanding of the craniometrics associated with each point.

Study Design: Retrospective cohort. Objective: The purpose was to investigate the incidence of and risk factors for complications associated with vertebroplasty (VP) or kyphoplasty (KP) for osteoporotic vertebral compression fracture (OVCF) using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. Methods: A cohort of patients undergoing VP/KP was constructed from the 2011-2013 ACS-NSQIP dataset using Current Procedural Terminology (CPT) codes. The incidences of minor complications (i.e. urinary tract infection, pneumonia, renal insufficiency, superficial infection, wound dehiscence), major complications (i.e. reoperation, deep vein thrombosis, pulmonary embolism, sepsis, dialysis, cardiac arrest, deep infection, stroke), and mortality within 30 days post-surgery were investigated, and their risk factors were assessed using logistic regression modeling. Results: Of 1932 patients undergoing VP/KP, 166 (8.6%) experienced a complication, including minor complications in 53 (2.7%), major complications in 95 (4.9%), and death in 40 (2.1%). Multivariate logistic regression analysis indicated that the adjusted odds ratios (95% confidence interval [CI]) of mortality was significantly associated with ASA 4: 16.604 (1.956-140.959) and increased creatinine (≥ 1.3 mg/dL): 3.494 (1.128-10.823). History of chronic obstructive pulmonary disease was associated with minor complications. Increased WBC count and hypoalbuminemia (<3.0 g/dL) were also associated with major complications. Conclusions: The major complication and mortality rates associated with VP/KP were 4.9% and 2.1% respectively, higher than previous reports. Increased creatinine and ASA 4 were independently associated with mortality after VP/KP. Therefore, cautious monitoring and counseling is needed for elderly, patients with preexisting kidney disease or ASA 4 undergoing VP/KP.

PurposeThe modified Japanese Orthopedic Association (mJOA) score consists of six sub-domains and is used to quantify the severity of cervical myelopathy. The current study aimed to assess for predictors of postoperative mJOA sub-domains scores following elective surgical management for patients with cervical myelopathy and develop the first clinical prediction model for 12-month mJOA sub-domain scores.Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name).

ArcherMethodsA multivariable proportional odds ordinal regression model was developed for patients with cervical myelopathy. The model included patient demographic, clinical, and surgery covariates along with baseline sub-domain scores. The model was internally validated using bootstrap resampling to estimate the likely performance on a new sample of patients.ResultsThe model identified mJOA baseline sub-domains to be the strongest predictors of 12-month scores, with numbness in legs and ability to walk predicting five of the six mJOA items. Additional covariates predicting three or more items included age, preoperative anxiety/depression, gender, race, employment status, duration of symptoms, smoking status, and radiographic presence of listhesis. Surgical approach, presence of motor deficits, number of surgical levels involved, history of diabetes mellitus, workers’ compensation claim, and patient insurance had no impact on 12-month mJOA scores.ConclusionOur study developed and validated a clinical prediction model for improvement in mJOA scores at 12 months following surgery. The results highlight the importance of assessing preoperative numbness, walking ability, modifiable variables of anxiety/depression, and smoking status. This model has the potential to assist surgeons, patients, and families when considering surgery for cervical myelopathy.Level of evidenceLevel III.

ObjectivesTo evaluate factors associated with clinic follow-up after traumatic spinal injury (TSI) in Tanzania, focusing on demographic, injury-related and hospital variables. We hypothesised that socioeconomic and injury-specific factors would predict follow-up adherence.DesignRetrospective observational cohort study.SettingTertiary government referral centre for neurosurgery and orthopaedics in Dar es Salaam, Tanzania.Participants443 adults with TSI admitted between September 2016 and October 2021. Inclusion criteria included survival to discharge and availability of the discharge date. Patients with missing data were excluded.Primary and secondary outcome measuresPrimary outcomes were any clinic follow-up and 1-year follow-up post-discharge. Secondary outcome was time to loss of follow-up. Logistic regression was used to identify factors associated with follow-up, and Kaplan-Meier survival analysis assessed follow-up duration.ResultsOf 443 patients (85.8% male, median age 34 years), 52.4% returned for follow-up. Independent factors associated with return included private insurance (adjusted OR (aOR) 2.69, 95% CI 1.38 to 5.45, p=0.005), involvement in a road traffic accident (aOR 2.15, 95% CI 1.22 to 3.83, p=0.009), lumbar injuries (aOR 2.26, 95% CI 1.30 to 4.00, p=0.004), neurological improvement at discharge (aOR 3.52, 95% CI 1.72 to 7.64, p=0.001) and hospital stays shorter than 24 days (aOR 1.63, 95% CI 1.07 to 2.47, p=0.022). Among those who returned, only 25.4% completed 1 year of follow-up. Predictors of 1-year follow-up included being female (aOR 4.87, 95% CI 2.31 to 10.56, p<0.001) and having American Spinal Injury Association Impairment Scale B–D versus E at admission (aOR 2.49, 95% CI 1.10 to 6.00, p=0.034). Kaplan-Meier analysis revealed that only 13.3% remained in follow-up at 12 months.ConclusionFollow-up after TSI in this low- and middle-income country setting is poor, with fewer than one in eight patients completing 1 year. Private insurance, injury mechanism, neurological improvement and female sex predicted follow-up. Targeted efforts are needed to improve long-term care engagement.

Purpose of ReviewSport-related concussion (SRC) and mild traumatic brain injury (mTBI) have been thrust into the national spotlight, with youth athletes bearing the burden of this public health problem. The current review aims to provide a practical summary of pediatric SRC, including key terminology, return to play/school, and risk factors for post-concussion syndrome (PCS).Recent FindingsWhile the majority of youth athletes recover within 2 to 4 weeks, approximately 10% of athletes experience a protracted recovery with symptoms lasting months, impacting social, scholastic, and sporting activities.SummaryIn the pediatric population, the strongest predictors of PCS are initial symptom burden and prior concussion, with mixed results behind the factors of gender, headaches, and learning disability. The role of psychiatric, family history, sports, and socioeconomic factors remain in their infancy.

Abstract BACKGROUND: Antiepileptic drugs (AEDs) are frequently administered prophylactically to mitigate seizures following craniotomy for brain tumor resection. However, conflicting evidence exists regarding the efficacy of AEDs, and their influence on surgery-related outcomes is limited. OBJECTIVE: To evaluate the influence of perioperative AEDs on postoperative seizure rate and hospital-reported quality metrics. METHODS: A retrospective cohort study was conducted, incorporating all adult patients who underwent craniotomy for glioma resection at our institution between 1999 and 2014. Patients in 2 cohorts—those receiving and those not receiving prophylactic AEDs—were compared on the incidence of postoperative seizures and several hospital quality metrics including length of stay, discharge status, and use of hospital resources. RESULTS: Among 342 patients with glioma undergoing cytoreductive surgery, 301 (88%) received AED prophylaxis and 41 (12%) did not. Seventeen patients (5.6%) in the prophylaxis group developed a seizure within 14 days of surgery, compared with 1 (2.4%) in the standard group (OR = 2.2, 95% CI [0.3-17.4]). Median hospital and intensive care unit lengths of stay were similar between the cohorts. There was also no difference in the rate at which patients presented within 90 days postoperatively to the emergency department or required hospital readmission. In addition, the rate of hospital resource consumption, including electroencephalogram and computed tomography scan acquisition, and neurology consultation, was similar between both groups. CONCLUSION: The administration of prophylactic AEDs following glioma surgery did not influence the rate of perioperative seizures, nor did it reduce healthcare resource consumption. The role of perioperative seizure prophylaxis should be closely reexamined, and reconsideration given to this commonplace practice.

Purpose (a) Describe the time course of each mechanical complication, and (b) compare radiographic measurements and preoperative patient-reported outcome measures (PROMs) among each mechanical complication type. Methods A single-institution case–control study was undertaken of patients undergoing adult spinal deformity (ASD) surgery from 2009–2017. Exposure variables included patient demographics, operative variables, radiographic measurements, and preoperative PROMs, including Oswestry Disability Index (ODI), Numeric Rating Scale Back/Leg-pain scores (NRS-Back/Leg), and EuroQol-5D (EQ-5D). The primary outcomes were occurrence of a mechanical complication and time to complication. Due to overlapping occurrence, rod fracture and pseudarthrosis were grouped into one composite category. Results 145 patients underwent ASD surgery and were followed for at least 2 years. 30/47 (63.8%) patients with proximal junctional kyphosis (PJK) required reoperation, whereas 27/31 (87.1%) patients with pseudarthrosis/rod fracture required reoperation (63.8% vs. 87.1%, Χ 2  = −0.23, 95% CI −0.41, −0.05, p  = 0.023). Cox regression showed no significant difference in time to reoperation between PJK and rod fracture/pseudarthrosis (HR = 0.97, 95% CI 0.85–1.11, p  = 0.686). Distal junctional kyphosis (DJK) ( N  = 3; 2 reoperation) and implant failures ( N  = 4; 0 reoperations) were rare. Patients with PJK had significantly lower Hounsfield Units preoperatively compared to those with pseudarthrosis/rod fracture (138.2 ± 43.8 vs. 160.3 ± 41.0, mean difference (MD) =  −22.1, 95% CI −41.8, −2.4, p  = 0.028), more prior fusions (51.1% vs. 25.8%, Χ 2  = 0.253, 95% CI 0.41, 0.46, p  = 0.026), fewer instrumented vertebrae (9.2 ± 2.6 vs. 10.7 ± 2.5, MD =  −1.5, 95% CI −2.7, −0.31, p  = 0.013), and higher postoperative thoracic kyphosis (TK) (46.3 ± 12.7 vs. 34.9 ± 10.6, MD = 11.4, 95% CI 5.9, 16.9, p  < 0.001). Higher postoperative C7 sagittal vertical axis (SVA) did not achieve a significant difference (80.7 ± 72.1 vs. 51.9 ± 57.3, MD = 28.8, 95% CI −1.9, 59.5, p  = 0.066). No differences were seen in preoperative PROMs. Conclusion Patients with pseudarthrosis/rod fracture had a higher reoperation rate compared to those with PJK with similar time to reoperation. Moreover, patients with PJK had higher postoperative TK, lower Hounsfield Units, more prior fusions, and fewer instrumented levels compared to those with pseudarthrosis/rod fracture. The results of this single-institution study suggest that even though mechanical complications are often analyzed as a single group, important differences may exist between them.
