Open Ankle Fractures in Older Individuals: A Multi-center Study.

The purpose of this study is to identify demographics, etiology, comorbidities, treatment, complications, and outcomes for older patients with open ankle fractures. Patients ≥60 years old who sustained an open ankle fracture between January 1, 2004 - March 31, 2014 at 6 Level 1 trauma centers were retrospectively reviewed. Univariate analysis using Chi-squared or Student's T-test was performed to identify associations between preoperative variables and two postoperative outcomes of interest: amputation and 1-year mortality. Multivariate analysis was performed using stepwise logistical regression to identify independent predictors of postoperative amputation and 1-year mortality. Of the 162 total patients, the most common mechanism of injury was a ground-level fall (51.9%). The most common fracture types were bimalleolar fractures (52.5%) followed by trimalleolar fractures (26.5%), with 41.5% of the fractures classified as Gustilo Anderson Classification Type 2 and 38.6% classified as Type 3A. The average number of surgeries required per patient was 2.1. Complications included: 15.4% superficial infection rate, 9.9% deep infection rate, and 9.3% amputation rate. The 1-year mortality rate was 13.6% and the overall mortality rate was 25.9%. Male gender and fracture type were found to be independent predictors for amputation after surgery (P = 0.009, 0.005, respectively). Older age and having diabetes were independent predictors for 1-year mortality after surgery (P = 0.021, 0.005 respectively). Overall, open ankle fractures in older individuals were associated with high rates of amputation and mortality.

Correlation of Radiographic Healing on Advanced Imaging in Young Adults and Adolescents with Symptomatic Spondylolysis Before and After Treatment: A Retrospective Study.

STUDY DESIGN: Retrospective chart-review. OBJECTIVE: To determine the effect of conservative measures on radiographic outcomes in those with isolated spondylosis. SUMMARY OF BACKGROUND DATA: Spondylosis is a common cause of low back pain in pediatric patients, affecting between 4.4 and 4.7% of all pediatric patients. This rate is even higher in high-level athletes, with recent studies suggesting a rate of 47% in this population. Conservative measures are recommended for treating symptomatic spondylosis and are effective in controlling symptoms, but there is little evidence regarding their effect on radiographic outcomes. METHODS: A retrospective review was conducted of patients diagnosed with spondylosis who were treated at a single academic institution between January 1st, 2012, and January 1st, 2022. Data collected included demographics, presentation characteristics, pre- and post-treatment radiologic findings, types of treatments employed, and final symptomatic status at follow-up. The student's t-test and the Wilcoxon rank sum test were used to compare continuous variables. The Chi-Squared test was used to compare categorical variables. RESULTS: A total of 119 patients were included in the study. There was an 81.5% rate of healing on advanced imaging for those treated with conservative measures. When comparing those with healing on advanced imaging to those without, those with healing were more likely to have an acute fracture (P=0.04), have symptomatic improvement (P<0.01), and return-to-play (P=0.02) compared to those without. Those with healing also had an odds ratio of 6.9 (P<0.01) and 4.5 (P=0.02) to achieve symptomatic improvement and return to their sport, respectively, compared to those who did not. CONCLUSION: Our study found those with isolated spondylosis who were treated with conservative measures had a high healing rate on advanced imaging and those with healing had significantly higher odds of having symptomatic improvement and returning-to-play compared to those without. LEVEL OF EVIDENCE: IV.

Interpreting the Current Literature on Outcomes of Robotic-Assisted Versus Conventional Total Knee Arthroplasty Using Fragility Analysis: A Systematic Review and Cross-Sectional Study of Randomized Controlled Trials.

BACKGROUND: Fragility analysis is a method of further characterizing outcomes in terms of the stability of statistical findings. This study assesses the statistical fragility of recent randomized controlled trials (RCTs) evaluating robotic-assisted versus conventional total knee arthroplasty (RA-TKA versus C-TKA). METHODS: We queried PubMed for RCTs comparing alignment, function, and outcomes between RA-TKA and C-TKA. Fragility index (FI) and reverse fragility index (RFI) (collectively, "FI") were calculated for dichotomous outcomes as the number of outcome reversals needed to change statistical significance. Fragility quotient (FQ) was calculated by dividing the FI by the sample size for that outcome event. Median FI and FQ were calculated for all outcomes collectively as well as for each individual outcome. Subanalyses were performed to assess FI and FQ based on outcome event type and statistical significance, as well as study loss to follow-up and year of publication. RESULTS: The overall median FI was 3.0 (interquartile range, [IQR] 1.0 to 6.3) and the median reverse fragility index was 3.0 (IQR 2.0 to 4.0). The overall median FQ was 0.027 (IQR 0.012 to 0.050). Loss to follow-up was greater than FI for 23 of the 38 outcomes assessed. CONCLUSIONS: A small number of alternative outcomes is often enough to reverse the statistical significance of findings in RCTs evaluating dichotomous outcomes in RA-TKA versus C-TKA. We recommend reporting FI and FQ alongside P values to improve the interpretability of RCT results.

The Role of Liposomal Bupivacaine in Multimodal Pain Management Following Posterior Spinal Fusion for Adolescent Idiopathic Scoliosis: Faster and Farther With Less Opioids.

STUDY DESIGN: Retrospective controlled cohort. OBJECTIVE: To evaluate the effect of intraoperative liposomal bupivacaine (LB) infiltration on postsurgical pain management in adolescent idiopathic scoliosis (AIS) patients by analyzing postoperative opioid consumption, ambulation, and length of stay (LOS). SUMMARY OF BACKGROUND DATA: Optimal postoperative pain control for AIS patients undergoing posterior spinal fusion (PSF) is challenging. Multimodal pain management protocols provide adequate analgesia while decreasing opioid consumption. LB was recently approved for pediatric patients; however, use in AIS patients is understudied. METHODS: 119 consecutive patients with AIS who underwent PSF were included. Patients were divided into 2 groups: patients who received LB as erector spinae block in addition to the standard postoperative pain management protocol (Group A), and patients who received only the standard postoperative pain protocol (Group B). Oral morphine equivalents, intravenous opioid and valium consumption, pain scores (VAS), nausea/vomiting, ambulation distance and LOS were assessed. RESULTS: Group A experienced significantly lower total opioid consumption compared to Group B (44.5 mg vs. 70.2 mg). Morphine use was lower in Group A on postoperative day (POD) 0, and oxycodone use was lower in Group A on PODs 1 and 2. There was a higher proportion of patients who used only oral opioids in Group A (81% vs. 41%). Of patients requiring any intravenous opioids, 79% did not receive LB. A significantly higher proportion of LB patients were discharged on POD 2 (55% vs. 27%); therefore, LOS was shorter for Group A. Group A ambulated further postoperatively. There were no differences in pain scores, valium requirements or nausea/vomiting. CONCLUSIONS: LB was associated with decreased total opioid use, shorter LOS, and improved ambulation in AIS patients undergoing PSF. Including LB in multimodal pain management protocols proved effective in reducing opioid use while increasing mobilization in the immediate postoperative period. LEVEL OF EVIDENCE: 3.

Factors Associated with Various Types of Industry Payments to Academic Spine Surgeons in the Open Payments Database.

STUDY DESIGN: Retrospective Cohort Study. OBJECTIVE: The objective of this study was to investigate associations between spine surgeon characteristics and different types of industry payments. SUMMARY OF BACKGROUND DATA: Industry funding has played an important role in research and technological innovation within spine surgery, and industry payments supporting research have risen significantly in comparison to funding from other sources. To our knowledge, no studies have investigated academic spine surgeon characteristics associated with different categories of industry payments. MATERIALS AND METHODS: A query was conducted of the North American Spine Society (NASS) Spine Fellowship Directory from 2021-2022 to identify all orthopaedic or neurosurgical spine fellowship selection committee members. A PubMed search was utilized to collect information on surgeon academic productivity up through December 31, 2021. We then conducted a query of the Centers for Medicare and Medicaid Services (CMS) open payments website from 2015-2021 to collect payment records of spine fellowship selection committee members. RESULTS: On linear regression analysis, total publications (8,203, P<0.001), attending years (48,823, P<0.001), and publication rate (57,528, P=0.017) were associated with higher general payments. Southeast spine surgeons (80,043, P=0.038) and fellowship directors (79,874, P=0.007) were associated with more research payments. Total publications (7,409, P<0.001), attending years (47,100, P<0.001), and publication rate (47,511, P=0.040) were significantly associated with higher royalties. Having a Twitter/X account (60,800, P=0.018), being a director (51,605, P=0.034), total publications (492, P<0.001), and publication rate (6,444, P<0.001) were all predictive of greater consulting payments. CONCLUSIONS: Spine surgeons who are experienced, academically productive, fellowship directors, and engage with social media receive greater payments on average than their peers across various payment types. As industry influence continues to make its way into healthcare, experienced leaders in their respective fields will shoulder the responsibility to integrate private innovation in an effective and scientifically rigorous manner.

Risks of suicide in migraine, non-migraine headache, back, and neck pain: a systematic review and meta-analysis.

Objective: To conduct a systematic review and meta-analysis on suicidal ideation, attempts, and death in patients with head, neck, and back pain. Method: Search was performed using PubMed, Embase, and Web of Science from the date of the first available article through September 31, 2021. A random effects model was used to estimate the pooled odds ratios (ORs) and 95% confidence intervals (95% CI) for the association between suicidal ideation and/or attempt and head, back/neck pain conditions. Articles describing non-migraine headache disorders and death by suicide were also reviewed but not included in the meta-analysis due to an insufficient number of studies. Results: A total of 20 studies met criteria for systemic review. A total of 186,123 migraine patients and 135,790 of neck/back pain patients from 11 studies were included in the meta-analysis. The meta-analysis showed that the estimated risk of combined suicidal ideation and attempt in migraine [OR 2.49; 95% CI: 2.15-2.89] is greater than that in back/neck pain pain [OR 2.00; 95% CI: 1.63-2.45] compared to non-pain control groups. Risk of suicide ideation/planning is 2 folds higher [OR: 2.03; 95% CI: 1.92-2.16] and risk of suicide attempt is more than 3 folds higher [OR: 3.47; 95% CI: 2.68-4.49] in migraine as compared to healthy controls. Conclusion: There is an elevated risk of suicidal ideation and attempt in both migraine and neck/back pain patients in comparison to healthy controls, and this risk is particularly higher among migraine patients. This study underscores the critical need for suicide prevention in migraine patients.

The severity of preoperative anemia escalates risk of poor short-term outcomes after lumbar spine fusion.

OBJECTIVE: To evaluate how preoperative anemia severity affects 90-day outcomes of spinal fusion surgery. METHODS: A retrospective cohort study was conducted on adult lumbar fusion patients at a tertiary medical center. Patients were classified by World Health Organization anemia severity definitions for comparisons. Multivariate regression models were created to control for confounding variables, for all primary outcomes of transfusion requirements, non-home discharge, readmissions, complications, and length of stay. RESULTS: A total of 2582 patients were included: 2.7% with moderate-severe anemia, 11.0% with mild anemia, and 86.3% without anemia. Moderate-severe patients had the longest hospital stay (5.03 days vs 4.14 and 3.59 days, p < 0.001) and highest risk of transfusion (52.2% vs 13.0% vs 2.69%, p < 0.001), non-home discharge (39.1% vs 27.8% vs 15.4%, p < 0.001), readmission (7.25% vs 5.99% vs 3.36%, p = 0.023), and complications (13.0% vs 9.51% vs 6.20%, p = 0.012). On multivariable logistic regression, both patients with mild and moderate-severe anemia had an increased risk of transfusion (OR: 37.3, p < 0.001; OR: 5.25, p < 0.001, respectively) and non-home discharge (OR: 2.00, p = 0.021; OR: 1.71, p = 0.001, respectively) compared to patients without anemia. Anemia severity was not independently associated with complications or 90-day readmission. On multivariable linear regression, mild anemia (ß: 0.37, p = 0.001) and moderate-severe anemia (ß: 1.07, p < 0.001) were independently associated with length of hospital stay. CONCLUSION: Patients with moderate-severe preoperative anemia are at increased risk for longer length of stay, transfusions, and non-home discharge. Improved optimization of preoperative anemia may significantly reduce healthcare utilization, and surgeons should consider these risks in preoperative planning. LEVEL OF EVIDENCE: III.

Prevalence of Abnormal Ultrasonographic Findings in Asymptomatic Peroneal Tendons.

Background: The peroneus longus (PL) and peroneus brevis (PB) tendons comprise the lateral compartment of the leg and stabilize the foot during weightbearing. Peroneal tendinopathy can precipitate lateral ankle pain and induce functional disability. The progression of peroneal pathology to lateral ankle dysfunction is thought to stem from asymptomatic, subclinical peroneal tendinopathy. There may be clinical benefit to identifying asymptomatic patients with this condition before progression to disability. Various ultrasonographic characteristics have been observed in peroneal tendinopathy. The purpose of this study is to identify the frequency of subclinical tendinopathic characteristics in asymptomatic peroneal tendons. Methods: One hundred seventy participants underwent bilateral foot and ankle ultrasonographic examination. Images were assessed for abnormalities of the PL and PB tendons by a group of physicians who recorded frequencies of abnormalities. This team consisted of an orthopaedic surgeon specializing in foot and ankle surgery, a fifth-year orthopaedic surgery resident, and a family medicine physician with musculoskeletal sonographer certification. Results: A total of 340 PL and 340 PB tendons were assessed. Sixty-eight (20%) PL and 41 (12.1%) PB tendons had abnormal traits. Twenty-four PLs and 22 PBs had circumferential fluid, 16 PLs and 9 PBs had noncircumferential fluid, 27 PLs and 6 PBs had thickening, 36 PLs and 12 PBs had heterogenicity, 10 PLs and 2 PBs had hyperemia, and 1 PL had calcification. In Caucasian participants, male gender was associated with increased frequency of abnormal findings, but there were no other significant differences based on age, body mass index, or ethnicity. Conclusion: In our studied population of 170 patients who had no complaints of associated symptoms, we found that 20% of PLs and 12% of PBs displayed ultrasonographic abnormalities. When we included all unusual findings within and around the tendons, prevalence rates of ultrasonographic abnormalities were 34% for PLs and 22% for PBs. Level of Evidence: Level II, prospective cohort study.

Severe thrombocytopaenia induced by systemic lupus erythematosus presenting as haemorrhagic oral bullae in a paediatric patient.

Systemic lupus erythematosus (SLE) is an autoimmune disease with varying dermatological findings. We review a unique presentation of SLE with a literature review. A previously healthy early adolescent female presented with painful, oral mucosal bullae filled with sanguineous fluid. She endorsed a tender right knee, but examination revealed no additional abnormalities. CBC demonstrated severe pancytopaenia. Further workup, including Coombs positive RBCs and positive ANA, anti-Smith, and anti-dsDNA antibodies, confirmed Lupus as the aetiology of this patient's presentation. A form of blistering SLE and resultant thrombocytopaenia was likely responsible for the patient's oral manifestations. After receiving 60 g intravenous immunoglobulin and 3 days high-dose pulse corticosteroids, her dermatological symptoms resolved. Although cases of blistering SLE with mucosal bullae have been described in the literature, this is the first documented case of haemorrhagic mucosal bullae as the presenting symptom of thrombocytopaenia in SLE in a paediatric patient.

Opsoclonus myoclonus and ataxia syndrome with supraventricular tachycardia.

Pediatric opsoclonus-myoclonus and ataxia syndrome (OMAS) is a neurologic disorder characterized by disturbances in eye movement, muscle jerks, ataxia, sleep, and mood. In approximately 50% of cases, it is a paraneoplastic syndrome associated with a neuroblastoma. In the remaining cases, it is believed that the tumor is occult, has involuted, or there is a preceding immune-stimulating event. While neuroblastomas can be associated with other paraneoplastic syndromes, supraventricular tachycardia (SVT) is rarely reported in the literature, and to our knowledge, this is the first case of SVT secondary to idiopathic OMAS. Confounding treatment toxicity, including intravenous immunoglobulin and other immunomodulatory drugs, should be screened for possible cardiovascular side effects in OMAS patients. The development of cardiac arrhythmias during OMAS treatment is not a contraindication to therapy. In these patients, arrhythmias should be controlled with vagal maneuvers or antiarrhythmics as needed while OMAS treatment is completed.

Relationship Between Headache Characteristics and a Remote History of TBI in Veterans: A 10-Year Retrospective Chart Review.

BACKGROUND AND OBJECTIVES: The objective of this work was to examine the association between deployment-related traumatic brain injury (TBI) severity, frequency, and other injury characteristics with headache outcomes in veterans evaluated at a Veterans Administration (VA) polytrauma support clinic. METHODS: We conducted a retrospective chart review of 594 comprehensive TBI evaluations between 2011 and 2021. Diagnostic criteria were based on the Department of Defense/VA Consensus-Based Classification of Closed TBI. Adjusted odds ratios (AORs) and 95% CIs were estimated for headache prevalence (logistic), headache severity (ordinal), and prevalence of migraine-like features (logistic) with multiple regression analysis. Regression models were adjusted for age, sex, race/ethnicity, time since injury, and mental health diagnoses. RESULTS: TBI severity groups were classified as sub concussive exposure (n = 189) and mild (n = 377), moderate (n = 28), and severe TBI (n = 0). Increased headache severity was reported in veterans with mild TBI (AOR 1.72 [95% CI 1.15, 2.57]) and moderate TBI (AOR 3.89 [1.64, 9.15]) compared to those with subconcussive exposure. A history of multiple mild TBIs was associated with more severe headache (AOR 2.47 [1.34, 4.59]) and migraine-like features (AOR 5.95 [2.55, 13.77]). No differences were observed between blast and nonblast injuries; however, greater headache severity was reported in veterans with both primary and tertiary blast effects (AOR 2.56 [1.47, 4.49]). Alteration of consciousness (AOC) and posttraumatic amnesia (PTA) >30 minutes were associated with more severe headache (AOR 3.37 [1.26, 9.17] and 5.40 [2.21, 13.42], respectively). The length of time between the onset of last TBI and the TBI evaluation was associated with headache severity (AOR 1.09 [1.02, 1.17]) and prevalence of migraine-like features (AOR 1.27 [1.15, 1.40]). Last, helmet use was associated with less severe headache (AOR 0.42 [0.23, 0.75]) and lower odds of migraine-like features (AOR 0.45 [0.21, 0.98]). DISCUSSION: Our data support the notion of a dose-response relationship between TBI severity and headache outcomes. A history of multiple mild TBIs and longer duration of AOC and PTA are unique risk factors for poor headache outcomes in veterans. Furthermore, this study sheds light on the poor headache outcomes associated with subconcussive exposure. Past TBI characteristics should be considered when developing headache management plans for veterans.

Suicide Attempts in US Veterans with Chronic Headache Disorders: A 10-Year Retrospective Cohort Study.

OBJECTIVES: A large-scale retrospective analysis of veterans with chronic pain was conducted to examine (1) the annual incidence of suicide attempts (SA) in veterans with chronic headache and other chronic pain conditions, and (2) the risk of SA in men and women with chronic headache and chronic headache concurrent with traumatic brain injury (TBI) as compared to non-headache chronic pain. METHODS: This retrospective study (N=3,247,621) analyzed National Veterans Affair Health Administrative data of patients diagnosed with chronic head, neck, back and other chronic pain from 2000 to 2010. Multivariable Poisson regression was used to explore the relative risks of SA in veterans with chronic headache and chronic headache concurrent with TBI as stratified by sex. RESULTS: Veterans with chronic headaches had the highest annual incidence of SA (329 to 491 per 100,000) each year among all identified types of chronic pain conditions. Compared to other non-headache chronic pain, chronic headache is associated with increased risk of SA [men RR (1.48), CI (1.37,1.59); women RR (1.64), CI (1.28,2.09)], after adjusting for demographic factors, TBI, and psychiatric comorbidities. The risk increased further when chronic headache is comorbid with TBI [men RR (2.82), CI (2.60, 3.05); women RR (2.16, CI (1.67-2.78)]. CONCLUSION: Veterans with chronic headache have a higher risk of SA than those with other chronic pain and women with chronic headache are at a higher risk than men with chronic headache. Chronic headache concurrent with TBI further heightened this risk, especially in men. Our data underscore the importance of identifying specific types of chronic pain in veterans with comorbid TBI and sex disparity associated with SA when targeting suicide prevention measures.
