RESUMO
PURPOSE: Our systematic review and meta-analysis sought to assess how technology-assistance impacts (1) post-operative pain and (2) opioid use in patients undergoing primary total knee arthroplasty (TKA). METHODS: Four online databases were queried for studies published up to October 2021 that reported on pain and opioid usage between technology-assisted and manual TKA (mTKA) patients. Mantel-Haenszel (M-H) models were utilized to calculate pooled mean difference (MDs) and 95% confidence interval (CIs). Subgroup analyses were conducted to isolate robotic-arm assisted (RAA) and computed-assisted navigation (CAN) cohorts. Risk of bias was assessed for all included non-randomized studies with the Methodological Index for Non-Randomized Studies (MINORS) tool. For the randomized control trials included in our study, the Detsky scale was applied. RESULTS: Our analysis included 31 studies, reporting on a total of 761,300 TKAs (mTKA: n = 753,554; Computer-Assisted Navigation (CAN): n = 1,309; Robotic-Arm Assisted (RAA): n = 6437). No differences were demonstrated when evaluating WOMAC (MD: 0.00, 95% CI - 0.69 to 0.69; p = 1.00), KSS (MD: 0.01, 95% CI - 1.46 to 1.49; p = 0.99), KOOS (MD - 2.91, 95% CI - 6.17 to 0.34; p = 0.08), and VAS (MD - 0.54, 95% CI - 1.01 to - 0.007; p = 0.02) pain scores between cohorts. There was mixed evidence regarding how opioid consumption differed between TKA techniques. CONCLUSION: The present analysis demonstrated no difference in terms of pain across a variety of utilized patient-reported pain measurements. However, there were mixed results regarding how opioid consumption varied between manual and technology-assisted cohorts, particularly in the immediate post-operative period. LEVEL OF EVIDENCE: III.

BACKGROUND: Understanding mark-up ratios (MRs), the ratio between a healthcare institution's submitted charge and the Medicare payment received, for high-volume orthopaedic procedures is imperative to inform policy about price transparency and reducing surprise billing. This analysis examined the MRs for primary and revision total hip and knee arthroplasty (THA and TKA) services to Medicare beneficiaries between 2013 and 2019 across healthcare settings and geographic regions. METHODS: A large dataset was queried for all THA and TKA procedures performed by orthopaedic surgeons between 2013 and 2019, using Healthcare Common Procedure Coding System (HCPCS) codes for the most frequently used services. Yearly MRs, service counts, average submitted charges, average allowed payments, and average Medicare payments were analyzed. Trends in MRs were assessed. We evaluated 9 THA HCPCS codes, averaging 159,297 procedures a year provided by a mean of 5,330 surgeons. We evaluated 6 TKA HCPCS codes, averaging 290,244 procedures a year provided by a mean of 7,308 surgeons. RESULTS: For knee arthroplasty procedures, a decrease was noted for HCPCS code 27438 (patellar arthroplasty with prosthesis) over the study period (8.30 to 6.62; P = .016) and HCPCS code 27447 (TKA) had the highest median (interquartile range [IQR]) MR (4.73 [3.64 to 6.30]). For revision knee procedures, the highest median (IQR) MR was for HCPCS code 27488 (removal of knee prosthesis; 6.12 [3.83-8.22]). While no trends were noted for both primary and revision hip arthroplasty, median (IQR) MRs in 2019 for primary hip procedures ranged from 3.83 (hemiarthroplasty) to 5.06 (conversion of previous hip surgery to THA) and HCPCS code 27130 (total hip arthroplasty) had a median (IQR) MR of 4.66 (3.58-6.44). For revision hip procedures, MRs ranged from 3.79 (open treatment of femoral fracture or prosthetic arthroplasty) to 6.10 (revision of THA femoral component). Wisconsin had the highest median MR by state (>9) for primary knee, revision knee, and primary hip procedures. CONCLUSION: The MRs for primary and revision THA and TKA procedures were strikingly high, as compared to nonorthopaedic procedures. These findings represent high levels of excess charges billed, which may pose serious financial burdens to patients and must be taken into consideration in future policy discussions to avoid price inflation.

INTRODUCTION: As recent analyses have indicated that low-volume hospitals experience higher rates of complications following total knee arthroplasty (TKA), it remains important to evaluate how area deprivation index (ADI) of hospitals impacts the quantity of TKA performed. Our analysis sought to evaluate how the ADI of orthopedic surgeon's place of service influences TKA utilization. MATERIALS AND METHODS: The Medicare Provider Utilization and Payment Data Public Use File (MPUP-PUF) was queried to identify claims between 2013 and 2019 associated with Healthcare Common Procedure Coding System (HCPCS) code 27447 (TKA). The MPUP-PUF file was linked with publicly available ADI information as well as information regarding each provider's practice location. The Mann-Kendall trend test was used to analyze significant differences in TKA volume between ADI quintiles and differences in TKA volume overall between the years 2013 and 2019. An adjusted multivariable linear regression analysis was conducted to evaluate how ADI, and practice-specific characteristics, influenced TKA utilization volume. RESULTS: When isolating by ADI quintiles, no significant changes in TKA volume were demonstrated for Quintile 4 (Kendall's τ = 0.524; p = 0.13) and Quintile 5 (Kendall's τ = 0.524; p = 0.13) between 2013 and 2019. However, a significant increase in TKA volume over the study period was observed in Quintile 1 (Kendall's τ = 0.714 p = 0.034), Quintile 2 (Kendall's τ = 0.714 p = 0.034), and Quintile 3 (Kendall's τ = 0.905 p = 0.007). The adjusted multivariable linear regression model demonstrated that each increase in ADI quintile was associated with significantly lower TKA utilization (ß-estimate - 1.16; 95% CI - 2.04 to - 0.29; p = 0.009). CONCLUSIONS: Our findings suggest that resource deprivation contributes to disparities in TKA utilization. With the ongoing recognition of how social and neighborhood-level deprivation may influence access to end-stage osteoarthritis care and related perioperative outcomes, the present study serves to encourage continued efforts at ensuring equity in orthopedic care.

INTRODUCTION: As recent studies demonstrate an ongoing debate surrounding outcomes and complications with respect to different total hip arthroplasty (THA) approaches, patient-reported outcome measures (PROMs) may provide valuable information for clinician and patient decision-making. Therefore, our systematic review aimed to assess how surgical approach influences patient-reported outcomes. METHODS: 5 online databases were queried for all studies published between January 1, 1997 and March 4, 2022 that reported on PROMs across various surgical approaches to THA. Studies reporting on PROMs in primary THA patients segregated by surgical approach were included. Articles reporting on revision THA, hip resurfacing, and arthroscopy were excluded. Mantel-Haenszel (M-H) models were utilised to calculate the pooled mean difference (MDs) and 95% confidence interval (CIs). RESULTS: No differences between the DAA and other approaches were observed when evaluating HOOS (MD -0.28; 95% CI, -1.98-1.41; p = 0.74), HHS (MD 2.38; 95% CI, -0.27-5.03; p = 0.08), OHS (MD 1.35; 95% CI, -2.00-4.71; p = 0.43), FJS-12 (MD 5.88; 95% CI, -0.36-12.12; p = 0.06), VAS-pain (MD -0.32; 95% CI, -0.68-0.04; p = 0.08), and WOMAC-pain (MD -0.73; 95% CI, -3.85-2.39; p = 0.65) scores. WOMAC (MD 2.47; 95% CI, 0.54-4.40; p = 0.01) and EQ-5D Index (MD 0.03; 95% CI, 0.01-0.06; p = 0.002) scores were found to significantly favour the DAA cohort over the other approaches. Only the EQ-5D index score remained significant following sensitivity analysis. CONCLUSIONS: Superiority of any 1 approach could not be concluded based on the mixed findings of the present analysis. Although our pooled analysis found no significant differences in outcomes except for those measured by the EQ-5D index, a few additional metrics, notably the WOMAC, HHS, FJS-12, and VAS-pain scores, leaned in favour of the DAA.

Left ventricular aneurysms (LVAs) represent a rare yet critical complication arising from late-presenting myocardial infarction (MI). Here, we present the case of an 88-year-old male with chest pressure, elevated troponin, B-type natriuretic peptide, and lactate. The electrocardiogram showed sinus tachycardia and an old right bundle branch block. The patient was started on heparin infusion, but progressively worsening hypotension necessitated transfer to the intensive care unit and the initiation of vasopressors. The echocardiogram identified a focal aneurysm in the mid-anterolateral wall, moderate pericardial effusion with a coagulum, and tamponade physiology. Computed tomography angiography of the chest confirmed a moderate pericardial effusion with density consistent with hemopericardium. LVAs pose a substantial threat of cardiovascular morbidity and mortality. While echocardiography serves as the initial assessment method, supplemental imaging modalities may need to be utilized. Various complications have been reported with LVA, including thromboembolization, ventricular arrhythmias, pericardial effusion with tamponade, and left ventricular rupture which accounts for 5%-24% of all in-hospital deaths related to MI. Although LVAs are the most common mechanical complications following an MI, instances of contained aneurysm rupture leading to hemopericardium are infrequent and scarcely reported. High clinical suspicion and prompt imaging with echocardiography are essential for diagnosis. Determining the optimal timing and selection between surgical and percutaneous interventions necessitates additional research for informed decision-making.
RESUMO
INTRODUCTION: Although the 5-factor modified frailty index (mFI-5) has been shown to be an independent predictor of complications after primary total hip arthroplasty (THA), its predictive value has not been evaluated in the setting of hip fracture. We therefore assessed the utility of mFI-5 score as an independent predictor of morbidity and mortality in patients who underwent THA or hemiarthroplasty for femoral neck fracture. METHODS: The American College of Surgeons National Surgical Quality Improvement database was queried for all patients with femoral neck fractures treated with THA or hemiarthroplasty between 2006 and 2020. A multivariate logistic regression analysis was done using mFI-5 as a predictor while controlling for baseline demographic and clinical variables. RESULTS: In total, 45,185 patients (hemiarthroplasty: 37,645; THA: 7,540) were identified. For hemiarthroplasty patients, the mFI-5 strongly predicted risk of any complication (OR, 1.1; 95% CI, 1.1 to 1.2; P < 0.001), bleeding (OR, 1.2; 95% CI, 1.1 to 1.3; P < 0.001), and readmission (OR, 1.2; 95% CI, 1.1 to 1.3; P < 0.001). For THA patients, the mFI-5 was a strong predictor of any complication (OR, 1.2; 95% CI, 1.0 to 1.3; P = 0.023), pneumonia (OR, 1.4; 95% CI, 1.0 to 2.0; P = 0.047), and readmission (OR, 1.3; 95% CI, 1.1 to 1.6; P = 0.004). DISCUSSION: The mFI-5 is an independent predictor of morbidity and complications after hemiarthroplasty and THA for femoral neck fracture. Importantly, readmission risk was predicted by the mFI-5. The mFI-5 may present a valuable clinical tool for assessment of high-risk patients who might require additional resources and specialized care after femoral neck fracture.

INTRODUCTION: Although hip arthroscopy continues to be one of the most used arthroscopic procedures, no focused, comprehensive evaluation of reimbursement trends has been conducted. The purpose of this study was to analyze the temporal Medicare reimbursement trends for hip arthroscopy procedures. METHODS: From 2011 to 2021, the Medicare Physician Fee Schedule Look-Up Tool was queried for Current Procedural Terminology (CPT) codes related to hip arthroscopy (29860 to 29863, 29914 to 29916). All monetary data were adjusted to 2021 US dollars. The compound annual growth rate and total percentage change were calculated. Mann-Kendall trend tests were used to evaluate the reimbursement trends. RESULTS: Based on the unadjusted values, a significant increase in physician fee was observed from 2011 to 2021 for CPT codes 29861 (removal of loose or foreign bodies; % change: 3.49, P = 0.03) and 29862 (chondroplasty, abrasion arthroplasty, labral resection; % change: 3.19, P = 0.03). The remaining CPT codes experienced no notable changes in reimbursement based on the unadjusted values. After adjusting for inflation, all seven of the hip arthroscopy CPT codes were observed to experience a notable decline in Medicare reimbursement. Hip arthroscopy with acetabuloplasty (CPT: 29915) and labral repair (CPT: 29916) exhibited the greatest reduction in reimbursement with a decrease in physician fee of 24.69% ( P < 0.001) and 24.64% ( P < 0.001), respectively, over the study period. DISCUSSION: Medicare reimbursement for all seven of the commonly used hip arthroscopy services did not keep up with inflation, demonstrating marked reductions from 2011 to 2021. Specifically, the inflation-adjusted reimbursements decreased between 19.23% and 24.69% between 2011 and 2021.

INTRODUCTION: Mental and psychiatric status continue to be underscreened prior to total joint arthroplasty (TJA). Research on the role of resilience as a psychiatric factor affecting TJA outcomes remains limited. Therefore, our systematic review sought to evaluate the impact of patient resilience in TJA. METHODS: A systematic review of the literature from the Pubmed, MEDLINE, EBSCOhost, and Google Scholar online databases was performed in abidance with Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. Studies reporting on outcomes following primary total hip arthroplasty (THA) and/or total knee arthroplasty (TKA) segregated by patient resilience were included. Case reports, reviews, meta-analyses, and conference abstracts were excluded. Primary outcomes of interest included patient-reported outcomes (PROs), surgical outcomes, and postoperative opioid consumption. RESULTS: Twelve articles were included reporting on a total of 1,577 TJAs. There was a strong agreement that the Patient Reported Outcomes Measurement Information System (PROMIS)-Physical Health and Mental Health components were strongly predicted by patient resilience. However, there was inconclusive evidence regarding the impact of resilience on UCLA Activity Scales (UCLA) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) outcomes as well as postoperative hip and knee function. Similarly, conflicting evidence was presented regarding the effect of resilience on length of stay (LOS). Greater resilience was associated with reduced opioid usage in the immediate inpatient postoperative period. However, resilience had no significant effect on opioid requirements in the postoperative outpatient follow-up time frame. CONCLUSION: The present analysis demonstrated mixed, inconclusive evidence regarding the impact of resilience on postoperative outcomes. The paucity of research evaluating this relationship warrants further investigation, examining both short and long-term outcomes. Due to the limited literature evaluating resilience as a predictor of outcomes following TJA, we cannot definitively rule out resilience as a valuable metric and must further examine its utility as a preoperative screening tool. LEVEL OF EVIDENCE: III.
RESUMO
Background: The transdermal patch of bisoprolol available in Japan has been reported to demonstrate superior efficacy in preventing postoperative atrial fibrillation, possibly surpassing its oral counterpart. However, there has been no systematic review and meta-analysis assessing the efficacy of transdermal bisoprolol. Methods: A comprehensive systematic literature search was conducted on PubMed, Embase, and Cochrane to identify all relevant studies assessing the efficacy of transdermal bisoprolol in preventing postoperative atrial fibrillation. The search covered studies from inception up to December 4, 2023. For data analysis, Review Manager (RevMan) 5.4 software was employed, using a random-effects model to calculate risk ratios (RR) and 95% confidence intervals (CI). Results: Three studies, comprising a total of 551 patients (transdermal bisoprolol 228 and control 323), were included. There was a decreased risk of postoperative atrial fibrillation or atrial tachyarrhythmias in patients treated with transdermal bisoprolol (RR 0.43, 95% CI 0.27-0.67, p = .0002, I 2 = 0%). Conclusion: Transdermal administration of bisoprolol has consistently shown efficacy, and this pooled analysis supports its effectiveness. The heterogeneity of the included studies limits certain interpretations. Future randomized clinical trials may elucidate the superiority of transdermal administration over oral administration.
RESUMO
Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment, yet they come with a spectrum of immune-related adverse events, including cardiac complications. We present the case of a 72-year-old male with metastatic renal cell carcinoma who developed complete heart block and ventricular arrhythmias following pembrolizumab therapy. Despite no evidence of myocarditis, the patient's condition rapidly deteriorated, ultimately resulting in his demise. This case underscores the critical need for vigilance in recognizing and managing potential cardiotoxicity associated with ICIs. Additionally, it highlights the importance of multidisciplinary collaboration in optimizing diagnostic and therapeutic strategies for patients undergoing immune checkpoint inhibitor therapy.
RESUMO
STUDY DESIGN: Retrospective cohort study. OBJECTIVE: (1) To develop a reliable grading system to assess the severity of posterior intervertebral osteophytes and (2) to investigate the impact of posterior intervertebral osteophytes on clinical outcomes after L5-S1 decompression and fusion through anterior lumbar interbody fusion (ALIF) and minimally-invasive transforaminal lumbar interbody fusion (MIS-TLIF). BACKGROUND: There is limited evidence regarding the clinical implications of posterior lumbar vertebral body osteophytes for ALIF and MIS-TLIF surgeries and there are no established grading systems that define the severity of these posterior lumbar intervertebral osteophytes. PATIENTS AND METHODS: A retrospective analysis of patients undergoing L5-S1 ALIF or MIS-TLIF was performed. Preoperative and postoperative patient-reported outcome measures of the Oswestry Disability Index (ODI) and leg Visual Analog Scale (VAS) at 2-week, 6-week, 12-week, and 6-month follow-up time points were assessed. Minimal clinically important difference (MCID) for ODI of 14.9 and VAS leg of 2.8 were utilized. Osteophyte grade was based on the ratio of osteophyte length to foraminal width. "High-grade" osteophytes were defined as a maximal osteophyte length >50% of the total foraminal width. RESULTS: A total of 70 consecutive patients (32 ALIF and 38 MIS-TLIF) were included in the study. There were no significant differences between the two cohorts in patient-reported outcome measures or achievement of MCID for Leg VAS or ODI preoperatively or at any follow-ups. On multivariate analysis, neither the surgical approach nor the presence of high-grade foraminal osteophytes was associated with leg VAS or ODI scores at any follow-up time point. In addition, neither the surgical approach nor the presence of high-grade foraminal osteophytes was associated with the achievement of MCID for leg VAS or ODI at 6 months. CONCLUSION: ALIF and MIS-TLIF are both valid options for treating degenerative spine conditions and lumbar radiculopathy, even in the presence of high-grade osteophytes that significantly occupy the intervertebral foramen. LEVEL OF EVIDENCE: 3.

The current guidelines state that propafenone can be used in combination with a beta-blocker or a calcium channel blocker for pharmacologic cardioversion of recent-onset atrial fibrillation in patients without structural heart disease. To prevent the conversion from atrial fibrillation to atrial flutter with a rapid ventricular rate, it is recommended to administer propafenone following the administration of a beta-blocker or a calcium channel blocker. However, this combination carries the potential risk of cardiogenic shock. There are several scenarios where this combination can lead to shock, attributed to the variable pharmacokinetics of propafenone among individuals and its significant drug interactions with commonly used AV nodal blockers, such as metoprolol and diltiazem. Additionally, a significant proportion of the population has genetic polymorphisms that affect the metabolism of these medications. While pill-in-the-pocket propafenone is also employed in outpatient settings, unexpected severe and life-threatening reactions have been reported. In this context, we present a case report of severe propafenone toxicity in a closely monitored inpatient setting aimed at converting atrial fibrillation.
RESUMO
The foramen ovale serves as an opening between the right and left atria at the site of the fossa ovalis in the fetus during uterine life. During fetal life, it makes it possible for venous blood from the maternal placenta with oxygen and nutrients to bypass the immature fetal lung and get transported to the left side of the heart and onto the systemic circulation. This hole from the right to the left atrium is usually occluded at the time of birth or shortly after birth, due to increased pressures in the left-sided cardiac cavities associated with normal breathing during delivery or shortly afterwards. If the foramen ovale remains open and fails to fuse beyond the first year of life, it is known as a patent foramen ovale (PFO). PFO occurs when, during fetal life, the septum primum and secundum, which develop and overlap normally, fail to fuse at birth. This results in the persistence of communication between the right and left atria. Paradoxical embolism from the right to the left side of the heart can occur through a PFO, causing a cryptogenic stroke or embolic stroke of an undetermined source in an otherwise healthy adult. There was a debate on the long-term benefits of closure. However, data from the randomized evaluation of the recurrent stroke comparing PFO closure to established current standard of care treatment (RESPECT) trial and two randomized trials (patent foramen ovale closure or anticoagulants versus antiplatelet therapy to prevent stroke recurrence (CLOSE) and reduction by dutasteride of prostate cancer events (REDUCE)) have clarified that there is a benefit to closure. In this case report, we describe a patient who presented with cryptogenic stroke, the investigations, imaging modalities for diagnosis of PFO, and procedure for closure. We also describe long-term outcomes and management following closure.
RESUMO
Cocaine overdose remains a significant public health concern worldwide, with potentially life-threatening consequences. The range of presentation can vary from mild autonomic hyperactivity to severe vasoconstriction, causing multiorgan ischemia and even death. In cases of high-dose intoxication, the presentation can be atypical. In this case report, we present a compelling case of a patient who initially presented with cardiac arrest and atypical signs. The patient made a remarkable recovery and returned almost to her baseline. This case provides valuable prognostic insight into the outcomes of severe multiorgan failure resulting from cocaine toxicity.
RESUMO
Background and rationale The impact of meteorological factors, including atmospheric temperature, humidity, and wind speed, on the incidence of atrial fibrillation and flutter (AF) has been the subject of several studies, but the findings have been inconsistent. Given the complex and multifaceted nature of this relationship, a larger-scale study was necessary to provide sufficient statistical power and elucidate potential associations between them. The aim of this study was, thus, to investigate the potential associations between meteorological factors and the incidence of AF. Methods The South Korean government provides open access to national health insurance and weather data for its citizens; the data was available from January 2010 to July 2022. The national health insurance data includes the monthly number of patients diagnosed with a specific condition, reflecting the incidence and prevalence of the condition. Pearson correlation analyses were performed using the statistical analysis software, SAS® OnDemand for Academics (SAS Institute Inc., Cary, North Carolina, United States), to examine the association between each month's national average climate data and the number of patients diagnosed with AF. Results The number of patients diagnosed with AF in the total population showed a statistically significant correlation only with average wind speed (correlation coefficient (r)=-0.42, 95%CI -0.55 to -0.28, p<0.001) and sunshine duration (r=0.27, 95%CI 0.12 to 0.41, p<0.001). Among females aged 20-24 years, there was a statistically significant association with other variables, including average temperature, precipitation, humidity, and atmospheric pressure (p<0.05). Diurnal temperature variation showed inconsistent associations across different age and sex groups. Conclusion The number of patients diagnosed with AF is negatively correlated with average wind speed and positively correlated with sunshine duration in the general population, particularly among the elderly. There was no significant association between the number of patients diagnosed with AF and average temperature, precipitation, or humidity, except for females aged 20-24 years, who exhibited a significant association with these variables. However, it is important to note that these correlations do not establish causality.
RESUMO
PURPOSE: Cervical disk arthroplasty (CDA) has emerged as a promising alternative to anterior cervical discectomy and fusion for the management of cervical disk degeneration causing neurological symptoms. This manuscript and accompanying digital content demonstrate the senior author's preferred surgical technique for a single-level CDA. METHODS: CDA is performed using a standard, left-sided Smith Robinson approach. A complete discectomy is performed, with resection of the posterior longitudinal ligament and decompression of the neuroforamina bilaterally. Careful endplate preparation and trial is performed, and the final implant is impacted under a combination of direct visualization and fluoroscopy. Postoperatively, a soft collar is worn for comfort, and the patient is discharged on postoperative day 1 or 2. RESULTS: This video, Supplemental Digital Content 1, http://links.lww.com/CLINSPINE/A254 presents the case of a 43-year old woman with mild cervical spondylosis with a paracentral disk herniation causing left C6 radiculopathy refractory to conservative measures. A C5-6 cervical disk arthroplasty was performed. CONCLUSIONS: CDA presents a motion-sparing alternative to anterior cervical discectomy and fusion and has the potential to reduce adjacent segment disease, though further studies are needed to fully determine its benefits and expanding indications. Careful patient selection and proper surgical technique, as demonstrated here, remain crucial in optimizing outcomes.

Bleeding rectal varices in cirrhotic patients with portal hypertension can be difficult to treat endoscopically or surgically. Transjugular intrahepatic portosystemic shunt creation offers a minimally invasive method to effectively decompress the portal system but may be contraindicated in patients with poor hepatic reserve or hepatic encephalopathy. We present a case of a 44-year-old woman with persistent rectal variceal bleeding, who was a poor candidate for endoscopic intervention, surgery, or transjugular intrahepatic portosystemic shunt. We therefore performed balloon-occluded antegrade transvenous obliteration of the rectal varices via transjugular intrahepatic access, which effectively controlled her rectal bleeding.
