ChatGPT as a Source of Patient Information for Lumbar Spinal Fusion and Laminectomy: A Comparative Analysis Against Google Web Search.

STUDY DESIGN: Retrospective Observational Study. OBJECTIVE: The objective of this study was to assess the utility of ChatGPT, an artificial intelligence chatbot, in providing patient information for lumbar spinal fusion and lumbar laminectomy in comparison with the Google search engine. SUMMARY OF BACKGROUND DATA: ChatGPT, an artificial intelligence chatbot with seemingly unlimited functionality, may present an alternative to a Google web search for patients seeking information about medical questions. With widespread misinformation and suboptimal quality of online health information, it is imperative to assess ChatGPT as a resource for this purpose. METHODS: The first 10 frequently asked questions (FAQs) related to the search terms "lumbar spinal fusion" and "lumbar laminectomy" were extracted from Google and ChatGPT. Responses to shared questions were compared regarding length and readability, using the Flesch Reading Ease score and Flesch-Kincaid Grade Level. Numerical FAQs from Google were replicated in ChatGPT. RESULTS: Two of 10 (20%) questions for both lumbar spinal fusion and lumbar laminectomy were asked similarly between ChatGPT and Google. Compared with Google, ChatGPT's responses were lengthier (340.0 vs. 159.3 words) and of lower readability (Flesch Reading Ease score: 34.0 vs. 58.2; Flesch-Kincaid grade level: 11.6 vs. 8.8). Subjectively, we evaluated these responses to be accurate and adequately nonspecific. Each response concluded with a recommendation to discuss further with a health care provider. Over half of the numerical questions from Google produced a varying or nonnumerical response in ChatGPT. CONCLUSIONS: FAQs and responses regarding lumbar spinal fusion and lumbar laminectomy were highly variable between Google and ChatGPT. While ChatGPT may be able to produce relatively accurate responses in select questions, its role remains as a supplement or starting point to a consultation with a physician, not as a replacement, and should be taken with caution until its functionality can be validated.

The Utility of the Standardized Letter of Recommendation for Orthopedic Surgery Residency Applicants: A Systematic Review.

Despite widespread adoption for evaluating residency candidates, few studies have evaluated the orthopedic standardized letter of recommendation (SLOR). A systematic review using PubMed, Embase, and Web of Science was performed in June 2022. Study design and results from SLOR investigations were compiled. Common outcomes studied were summative rank statement scores and SLOR individual domains. Applicants were rated ranked to match or in the top one-third of rank lists in non-normally distributed frequencies. The association of summative rank statement score with match outcome was rarely studied. Applicants' ratings skew positively, the utility is reportedly limited, and influence on match outcome has been inadequately studied. [Orthopedics. 2024;47(1):e1-e5.].

The association of congestive heart failure on in-hospital lengths of stay, morbidity, and financial burden following primary total knee arthroplasty.

BACKGROUND: Current literature states that 6.2 million adults in the United States are living with heart failure. Studies investigating the impact of congestive heart failure (CHF) following primary total knee arthroplasty (TKA) are scarce. Hence, this research aimed to investigate whether individuals with congestive heart failure (CHF) undergoing primary total knee arthroplasty (TKA) experience: (1) longer durations of in-hospital stay; (2) increased incidences of health complications; and (3) a higher financial load. METHODS: A retrospective query using the 100% Parts A and B of the Medicare claims was performed. Cohorts of interest were identified using International Classification of Disease, Ninth Revision (ICD-9) and Current Procedural Terminology. Inclusion criteria for the study group consisted of patients with CHF undergoing primary TKA, whereas patients without CHF undergoing primary TKA served as the comparison cohort. RESULTS: The query yielded 1,101,169 patients (CHF = 183,540; case-matched = 917,629). Patients with CHF had longer in-hospital LOS (5- vs. 4-days) and a higher incidence and odds of developing 90-day medical complications (49.22% vs. 7.45%) following primary TKA. CHF patients incurred higher day of surgery and total global ninety-day episode of care costs compared to their matched counterparts. CONCLUSION: This study illustrated those patients with preexisting CHF undergoing a primary TKA have longer in-hospital lengths of stay and higher rates of morbidity and financial burden. With the increasing prevalence of CHF worldwide, orthopedists and other healthcare professionals can utilize the information provided in this study to educate patients and establish comprehensive treatment plans to help mitigate postoperative effects associated with CHF.

Crohn's disease is associated with higher rates of implant-related complications following primary total knee arthroplasty.

INTRODUCTION: In Western countries, there has been a rise in the prevalence of Crohn's Disease (CD) and primary total knee arthroplasty (TKA). This study delves deeper into the effects of CD on TKA patients by examining (1) the length of in-hospital stay (LOS); (2) the rates of readmission; (3) complications related to implants; and (4) the costs associated with care. METHODS: A retrospective analysis using the PearlDiver database was conducted, encompassing the time frame between January 1st, 2005 and March 31st, 2014, focusing on patients who underwent TKA and were either diagnosed with CD or not. Patients with CD were paired with control subjects at a 1:5 ratio based on age, gender, and medical comorbidities. The analysis comprised a total of 96,229 patients (CD = 16,039; non-CD = 80,190). RESULTS: Patients with CD had a notably longer hospital stay (3 v. 2 days, p < 0.0001) and faced significantly higher rates of 90-day readmissions and complications (19.80% v. 14.91%, OR: 1.40, p < 0.0001; 6.88% v. 4.88%, OR: 1.43, p < 0.0001 respectively). Additionally, CD patients incurred greater expenses on the surgery day ($18,365.98 v. $16,192.00) and within 90 days post-surgery ($21,337.46 v. $19,101.42). CONCLUSION: This study demonstrates longer in-hospital LOS, higher rates of readmissions, implant-related complications, and costs of care among CD patients following primary TKA.

Cannabis Abuse Is Associated With Greater Medical Complications, Emergency Department Visits, and Readmissions Following Open Reduction and Internal Fixation for Distal Radius Fractures.

BACKGROUND: Despite increased legalization, little is known about the influence of cannabis use disorder (CUD) following open reduction and internal fixation (ORIF) for distal radius fractures (DRFs). The aims were to determine whether CUD patients undergoing ORIF for DRF have increased: (1) medical complications; and (2) health care utilization (emergency department [ED] visits and readmission rates). METHODS: Patients were identified from an insurance database from 2010 to 2020 using Current Procedural Terminology codes: 25607, 25608, and 25609. Patients with a history of CUD were 1:5 ratio matched to controls by age, sex, tobacco use, alcohol abuse, opioid dependence, and comorbidities. This yielded 13,405 patients with (n = 2,297) and without (n = 11,108) CUD. Outcomes were to compare 90-day medical complications, ED visits, and readmissions. Multivariable logistic regression models computed the odds ratios of CUD on dependent variables. P values less than .005 were significant. RESULTS: The incidence of CUD among patients aged 20 to 69 years undergoing ORIF increased from 4.0% to 8.0% from 2010 to 2020 (P < .001). Cannabis use disorder patients incurred significantly higher rates and odds of developing 90-day medical complications (15.24% vs 5.76%), including pneumoniae (3.66% vs 1.67%), cerebrovascular accidents (1.04% vs 0.32%), pulmonary emboli (0.57% vs 0.16%), respiratory failures (1.00% vs 0.48%), and surgical site infections (1.70% vs 1.04%; all P < .004). Emergency department visits (2.53% vs 1.14%) and readmission rates (5.79% vs 4.29%) within 90 days were higher among cannabis abusers. CONCLUSIONS: With a greater number of states legalizing cannabis, hand surgeons should be cognizant of the association with increased 90-day complications and health care utilization parameters.

Comparison of Patient Demographics, Utilization Trends, and Costs of Treatment for Dupuytren's Disease in the United States From 2012 to 2019.

INTRODUCTION: Dupuytren's disease is a fibroproliferative disorder of the palm leading to flexion deformities of the digits that impair hand function. Studies have evaluated treatment trends for patients with Dupuytren's disease; however, most conclude in 2012 shortly after collagenase clostridium histolyticum (CCH) injection was introduced to the market. It is unknown how provider preferences have been influenced since its introduction. We aimed to compare treatment options with regard to (1) patient demographics, (2) annual utilization rates, and (3) costs. METHODS: The PearlDiver nationwide administrative claims database from 2012 to 2019 was analyzed for patients diagnosed with Dupuytren's disease (N = 47,813). Patients receiving procedural treatment were identified using codes for percutaneous needle aponeurotomy (PNA) (current procedural terminology [CPT] 26040), open fasciotomy (CPT 26045), open fasciectomy (CPT 26121, 26123, 26125), and CCH injection (CPT 20527). Fasciectomies were further analyzed by examining the number of patients receiving release of 1 or more digits (CPT 26123, 26125) versus palmar-only surgery (CPT 26121). Outcomes included comparing patient comorbidities comprising the Elixhauser Comorbidity Index (ECI), frequencies of each procedure annually, and costs. Linear regressions evaluated changes in utilization over time. Analysis of variance compared costs. P values less than 0.05 were significant. RESULTS: Patient demographics for each treatment differed with respect to age, sex, and the presence of multiple comorbidities comprising the ECI. Open fasciectomy (60.7%) was the predominant treatment, followed by CCH injection (22.9%), PNA (10.1%), and open fasciotomy (6.3%) ( P < 0.001). Multiple patient comorbidities comprising the ECI differed for each treatment. Relative to total annual procedures from 2012 to 2019, PNA declined (10.2% to 9.5%, P = 0.037), open fasciotomy declined (6.8% to 5.6%, P = 0.007), palmar fasciectomy remained constant (14.5% to 14.2%, P = 0.710), fasciectomy of digits increased (46.3% to 47.5%, P = 0.030), and CCH injection remained constant (22.2% to 23.3%, P = 0.623). Day of procedure costs were significantly different for PNA ($573), open fasciotomy ($1176), palmar open fasciectomy ($1410), open fasciectomy digits ($1560), and CCH injection ($1250) ( P < 0.001). CONCLUSIONS: The overall annual Dupuytren's disease treatment did not change over time. Treatment with open fasciectomy continues to be preferred. Collagenase clostridium histolyticum utilization has remained constant since its introduction. This study may assist hand surgeons in educating patients on the treatment and costs related to Dupuytren's disease.

Comparison of baseline demographics and risk factors for aseptic loosening following primary total elbow arthroplasty.

BACKGROUND: Aseptic loosening is a feared complication following total elbow arthroplasty (TEA); however, literature regarding factors that may contribute to this complication is limited. The aims of this investigation were to: (1) compare baseline demographics of patients who developed aseptic loosening following primary TEA; and (2) identify patient-specific risk factors for the development of loosening. METHODS: Retrospective analysis using a nationwide claims database was performed to identify patients who underwent primary TEA and developed aseptic loosening within 2 years (study n = 307, control n = 10,741). Multivariate regression analysis generated odds ratio (OR), 95% confidence interval (95% CI), and p-value of risk factors. p < 0.05 was considered statistically significant. RESULTS: Patients who developed aseptic loosening had significant differences in numerous demographics, including age (p = 0.0001), sex (p = 0.0251), and various comorbid conditions such as obesity (15.96% vs. 8.36%, p < 0.0001). Furthermore, the risk factors most associated with aseptic loosening were obesity (OR 1.65, 95% CI 1.18-2.28, p = 0.002), male sex (OR 1.51, 95% CI 1.13-2.00, p = 0.004), and concomitant opioid use disorder (OR 1.58, 95% CI 1.14-2.15, p = 0.004). DISCUSSION: This study is the first to identify demographics and patient-related risk factors associated with aseptic loosening following primary TEA. This evidence could be applied to the clinical setting in order to educate at-risk patients of this potential complication as well as inform their post-operative clinical management. LEVEL OF EVIDENCE: Level III: Prognostic.

How does depressive disorder impact outcomes in patients with glenohumeral osteoarthritis undergoing primary reverse shoulder arthroplasty?

BACKGROUND: Current literature shows that the prevalence of depressive disorders (DD) is increasing in the United States. Patients with DD have worse outcomes after shoulder arthroplasty; however, properly defined inclusion and exclusion criteria evaluating the effects of DD on primary reverse shoulder arthroplasty (RSA) are limited. The purpose of this study was to compare the outcomes of patients with and without DD undergoing primary RSA, evaluating: (1) in-hospital length of stay (LOS), (2) medical complications, (3) emergency department (ED) utilizations, and (4) cost of care. METHODS: A retrospective query was performed using a nationwide administrative claims database from 2010 to 2020 for all patients who underwent primary RSA for the treatment of glenohumeral osteoarthritis. The query yielded a total of 24,326 patients within the study (DD, n = 4084) and comparison (without DD, n = 20,242) cohorts. The primary end points were in-hospital LOS, 90-day medical complications, and total 90-day episode of care costs. Subanalyses compared whether DD diagnosis and preoperative ED utilization within 6 months of RSA were associated with increased incidence and odds of postoperative ED utilization within 90 days. P values less than .004 were considered statistically significant. RESULTS: Patients with DD undergoing primary RSA had significantly longer LOS (3 vs. 2 days, P < .0001) compared with patients without DD. The study group also had higher frequency and odds ratio (OR) of complications (47.40% vs. 17.63%; OR: 2.27, P < .0001) such as pneumonia (10.04% vs. 2.15%; OR: 2.88, 95% confidence interval [CI]: 2.47-3.35, P < .0001), cerebrovascular accidents (3.13% vs. 0.86%; OR: 2.69, 95% CI: 2.09-3.46, P < .0001), myocardial infarctions (1.98% vs. 0.51%; OR: 2.54, 95% CI: 1.84-3.50, P < .0001), and other adverse events. Among patients who had a diagnosis of DD, preoperative ED utilization within 6 months of RSA was associated with increased odds of postoperative ED utilization within 90 days compared with those without ED utilization preoperatively (15.08% vs. 13.64%; OR: 1.16, 95% CI: 1.04-1.28, P = .003). Controlling for preoperative ED utilization and comorbidities, patients with DD experienced a 2- to 3-fold increase in postoperative ED use within 90 days after surgery (P < .0001). Patients with DD also incurred significantly higher episode of care costs ($19,363.10 vs. $17,927.55, P < .0001). CONCLUSION: This retrospective study shows that patients with DD undergoing primary RSA for the treatment of glenohumeral osteoarthritis have longer in-hospital LOS, higher rates of complications, and increased costs of care. Preoperative health care utilization among patients with DD may be associated with increased utilization postoperatively.

Benign prostatic hyperplasia is associated with increased 90-day medical complications but not peri-prosthetic joint infections following reverse shoulder arthroplasty.

INTRODUCTION: Studies have shown male sex to be a predisposing factor for peri-prosthetic joint infections (PJIs). Symptomatic benign prostatic hyperplasia (BPH) has been suggested as an additional risk for PJI. This study aimed to assess the impact of BPH on (1) lengths of stay (LOS), (2) complications (medical and implant-related), (3) readmission rates, and (4) healthcare expenditures after reverse shoulder arthroplasty (RSA). METHODS: Utilizing a nationwide sample from the 2010-2020 PearlDiver insurance database, an analysis was performed retrospectively for all males who underwent primary RSA. Males with BPH (n = 2,184) represented the study group and were ratio-matched with men without a history of BPH (n = 10,832) in a 1:5 manner by medical comorbidities. T-tests compared LOS and healthcare expenditures. Multivariate logistic regression models were used to determine the effect of BPH on 90-day medical complications, 2-year implant complications, and readmissions. A p value less than 0.001 was statistically significant. RESULTS: In-hospital LOS (1.96 days vs. 1.99 days, p = 0.683) did not significantly differ between cohorts. Males with BPH had significantly greater occurrence and odds (34.3% vs. 21.2%, odds ratio (OR):1.84, p < 0.0001) of all 90-day medical complications, including urinary tract infections (9.3% vs. 3.1%, OR:3.23, p < 0.0001), pneumonias (6.0% vs. 3.9%, OR:1.61, p < 0.0001), and acute kidney injuries (7.7% vs. 5.0%, OR:1.60, p < 0.0001). Two-year implant-related complications were comparable between study and control groups (12.2% vs 10.9%, OR:1.14, p = 0.073), including PJIs (2.3% vs. 2.2%, OR:1.02, p = 0.874). Readmission rates (1.88% vs. 2.11%, p = 0.482) and average global 90-day reimbursements ($26,301 vs. $24,399), p = 0.535) were similar between men with and without BPH. DISCUSSION: Males with a history of BPH have greater rates of medical complications, including UTIs and acute kidney injuries, within 90 days following RSA. BPH does not appear to be a risk factor for 2-year implant-related complications including PJIs. LEVEL OF EVIDENCE: III.

The 5-Item Modified Frailty Index for Risk Stratification of Patients Undergoing Total Elbow Arthroplasty.

BACKGROUND: Frailty, quantified using the 5-item modified frailty index (mFI-5), has been shown to predict adverse outcomes in orthopaedic surgery. The utility in total elbow arthroplasty (TEA) patients is unclear. We evaluated if increasing frailty would correlate with worse postoperative outcomes. METHODS: A retrospective assessment of patients in the American College of Surgeons National Surgery Quality Improvement Program undergoing primary TEA was performed. The mFI-5 was calculated by assigning 1 point for each comorbidity (diabetes, hypertension, congestive heart failure, chronic obstructive pulmonary disease, and functionally dependent health status). Poisson regression was used to evaluate mFI-5 scores on complications, length of stay (LOS), and adverse discharge. A significance threshold was at P < .05. RESULTS: In total, 609 patients were included; 34.5% (n = 210) were not frail (mFI = 0), 44.0% (n = 268) were slightly frail (mFI = 1), and 21.5% (n = 131) were frail (mFI ≥ 2). As mFI score increased from 0 to ≥ 2, the following rates increased: any complication (9.0%-19.8%), major complication (11.0%-20.6%), cardiac complication (0.0%-2.3%), hematologic complication (3.3%-9.2%), adverse discharge (2.9%-22.9%), and LOS from 2.08 to 3.97 days (all P < .048). Following adjustment, Poisson regression demonstrated patients with a mFI ≥ 2 had increased risk of major complication (risk ratio [RR]: 2.13; P = .029), any complication (RR: 2.49; P = .032), Clavien-Dindo IV complication (RR: 5.53; P = .041), and adverse discharge (RR: 5.72; P < .001). CONCLUSIONS: Frailty is not only associated with longer hospitalizations, but more major complications and non-home discharge. The mFI-5 is a useful risk stratification that may assist in decision-making for TEA.

The influence of prior dental pathology on medical complications and peri-prosthetic joint infections following primary shoulder arthroplasty.

PURPOSE: Antibiotic prophylaxis before invasive dental procedures is a common practice in the USA. Consensus regarding the influence of prior dental pathology (DP) on postoperative complications is lacking. The objectives are to determine the association of DP prior to shoulder arthroplasty (SA) on: (1) lengths of stay (LOS), (2) medical complications, (3) readmissions, (4) implant-related complications including peri-prosthetic joint infections (PJIs) and (5) healthcare expenditures. METHODS: The PearlDiver database was queried for primary shoulder arthroplasty from 2010 to 2020. Patients with history of dental caries or dental implant placement before SA represented the study group (n = 1419). Patients without prior DP represented controls (n = 7062). Study group patients were 1:5 ratio matched to controls by age, sex, and comorbidities. Outcomes included LOS, 90-day complications, readmissions, 2-year implant-related complications, and healthcare reimbursements. Logistic regression was used to calculate odds ratios (OR) of complications and readmissions. T tests compared LOS and costs. P values < 0.003 were significant. RESULTS: LOS (2.17 vs. 2.07 days; p = 0.071) were similar between groups. Patients with DP had higher 90-day medical complications compared to controls (OR: 1.74, p < 0.0001), including myocardial infarctions (2.2% vs. 0.8%; OR: 2.79, p < 0.0001), acute kidney injuries (8.3% vs. 4.6%; OR: 1.92, p < 0.0001), and pneumonias (8.7% vs. 5.3%; OR: 1.72, p < 0.0001). Readmission rates (1.97% vs. 1.54%; p = 0.248) were similar. Two-year implant complications were higher in patients with DP compared to controls (16.1% vs. 11.5%; OR: 1.38, p = 0.0003), including dislocations (6.4% vs. 4.5%; OR: 1.45, p = 0.002) and mechanical loosenings (4.0% vs. 2.4%; OR: 1.67, p = 0.001); however, PJIs were similar (2.2% vs. 1.9%; OR: 1.12, p = 0.583). Healthcare expenditures between groups were similar ($12,611 vs. $12,059; p = 0.075). CONCLUSION: Patients with prior DP have higher 90-day medical complications and 2-year implant-related complications. Two-year incidence of PJIs were similar between groups. These findings can help shoulder surgeons counsel patients with a pertinent dental history. LEVEL OF EVIDENCE III: Retrospective comparative study.

Resident and Fellow Participation Does Not Affect Short-Term Postoperative Complications After Distal Radius Fracture Fixation.

Background Complications after open reduction internal fixation (ORIF) for distal radius fractures (DRF) are well documented, but the impact of trainee involvement on postoperative outcomes has not been studied. Questions Does trainee involvement affect postoperative complication rates and length of hospital stay? Methods The American College of Surgeons National Surgical Quality Improvement Program was queried from 2006 to 2012 for patients undergoing DRF ORIF. A 1:1 propensity score matched resident/fellow involved cases to attending-only cases. Demographics, length of stay, and postoperative complications were compared between the two groups. Logistic regression was used to evaluate independent predictors of adverse events and to evaluate cases with and without trainee involvement. Results Overall, 3,003 patients underwent DRF ORIF from 2006 to 2012. After matching, 1,150 cases (50% with resident/fellow involvement) were included. The overall rate of adverse events was 4.4% (46/1,050). There were no significant differences in the short-term complication rate in trainee-involved (2.3%) versus attending-only cases (3.9%) ( p = 0.461). For ORIF of DRF, there were no significant differences, between attending-only cases and resident/fellow-involved cases, with regard to short-term major complications ( p = 0.720) or minor complications ( p = 0.374). Length of hospital stay was similar between cohorts (1.22 vs. 0.98 days) ( p = 0.723). On multivariate analysis, trainee involvement was not an independent predictor of minor, major, or any complication after DRF fixation after controlling for multiple independent factors (all p > 0.364). Discussion Trainee participation in DRF ORIF is not associated with increased risk of short-term (30 days) medical or surgical postoperative complications. Level of Evidence This is a Level IV case-control study.

Risk Factors for Infections Following Open Reduction and Internal Fixation for Distal Radius Fractures An Analysis of the Medicare Claims Database.

Bulletin of the Hospital for Joint Diseases 2022;80(2):228-33228 Mahmood B, Golub IJ, Ashraf AM, Ng MK, Vakharia RM, Choueka J. Risk factors for infections following open reduction and internal fixation for distal radius fractures: an analysis of the medicare claims database. Bull Hosp Jt Dis. 2022;80(2):228-33. Abstract Background: Infections following open reduction and internal fixation (ORIF) of distal radius fractures (DRFs) are associated with worse outcomes and increasing health care costs. The purpose of this study was to utilize a nationwide administrative claims database to compare patient demo- graphics of patients who did and did not develop infections and identify patient-related risk factors for postoperative infections. METHODS: Using the PearlDiver database, the 100% Medicare Files from 2005 to 2014 were queried. Patients undergoing ORIF for DRF were identified using Current Procedural Terminology (CPT) codes. Inclusion for the study group consisted of patients who developed infection within 90 days after the procedure and were identified us- ing CPT and International Classification of Disease, Ninth Revision (ICD-9) codes. Multivariable binomial logistic regression analyses were performed to calculate the odds (OR) of certain patient comorbidities and their association with infection following ORIF of DRFs. A p-value less than 0.002 was considered statistically significant after Bonfer- roni correction. RESULTS: The query yielded 132,650 patients within the study, 456 who developed surgical site infections (SSI) and 132,194 who did not. Surgical site infections were more commonly found in certain demographics, such as patients under the age of 65 (26.75 vs. 14.73%) and in males (20.83 vs. 14.15%). Multivariate regression analysis further highlighted that certain comorbidities increased odds for infections within 90-days following ORIF for distal radius fractures and those included: morbid obesity (OR: 2.06, p < 0.0001), depression (OR: 1.92, p = 0.0002), and pathologic weight loss (OR: 1.49, p = 0.001). CONCLUSION: The study found statistically significant dif- ferences between patients who developed and did not develop infection. These findings may help orthopedic surgeons to educate certain high-risk patients of the potential complica- tions that may occur following surgery.

The resiliency of elective total shoulder arthroplasty case volumes in the United States during the COVID-19 pandemic: a nationwide temporal trends analysis.

BACKGROUND: Total shoulder arthroplasty (TSA) is one of the fastest growing procedures in terms of volume performed in hospitals in the United States. In 2020, elective surgery was suspended nationwide as a result of the SARS-CoV-2 (COVID-19) pandemic, and the use trends in the wake of the pandemic have yet to be evaluated substantially. Nationwide case volume reduction for TSA is unknown; therefore, the aim of this study is to compare patient demographics, complications, and temporal trends in case volume of elective TSA in the calendar year 2019 (prepandemic) to 2020 in the United States. METHODS: Using a multicenter, nationwide representative sample from 2019 to 2020, a retrospective query was conducted for all patients undergoing elective TSA. Patients undergoing surgery pre-COVID (2019 and 2020 Q1) were compared to those during COVID (2020 Q2-Q4). Temporal trends in case volumes were compared between time frames. TSA use, patient demographics, complications, and length of stay were compared between years. Linear regression was used to evaluate for changes in the case volume over the study period. A statistical significance threshold of P <.05 was used. RESULTS: In total, 9667 patients underwent elective TSA in 2019 (n = 5342) and 2020 (n = 4325). The proportion of patients who underwent outpatient TSA in 2020 was significantly greater than the year prior (20.6% vs. 13.9%; P < .001). Overall, elective TSA case volume declined by 19.0% from 2019 to 2020. There was no significant difference in the volume of cases in 2019 Q1 (n = 1401) through 2020 Q1 (n = 1296) (P = .216). However, elective TSA volumes declined by 54.6% in 2020 Q2. Elective TSA case volumes recovered to prepandemic baseline in 2020 Q3 and 2020 Q4. The average length of stay was comparable in 2020 vs. 2019 (1.29 vs. 1.32 days; P = .371), with the proportion of same-day discharge increasing per quarter from 2019 to 2020 (from 11.8% to 26.8% of annual cases). There was no significant difference in the total complication rates in 2019 (4.6%) vs. 2020 (4.9%) (P = .441). CONCLUSION: Using a nationwide sample, elective TSA precipitously declined during the second quarter of 2020. Patient demographics of those undergoing elective TSA in 2020 were similar in comorbidity burden. A large proportion of surgeries were transitioned to the outpatient setting, with rates of same-day discharge doubling over the study period despite no change in overall complication rates.

The transition of total elbow arthroplasty into the outpatient theater.

BACKGROUND: Outpatient total joint arthroplasty is increasing in frequency as reimbursement models change. Potential benefits include same-day surgery for patients and decreased exposure to nosocomial pathogens. This study aims to determine if total elbow arthroplasty (TEA) is also trending toward an outpatient setting, and if there is any impact on complication rates as a result. METHODS: A retrospective chart review of the American College of Surgeons National Surgical Quality Improvement Program was performed. Specifically, the database was queried for all patients with CPT code 24363 from 2010-2017. The percentage of TEAs performed each year as an outpatient was trended from 2010-2017. Additionally, the complication rate between the inpatient and outpatient cohorts was compared. RESULTS: A total of 524 TEAs were analyzed. Of these, 111 procedures (21.2%) were performed as an outpatient. There was a statistically significant increase in the percentage of outpatient TEAs from 2010-2017 (P = .0016). In 2010, 2.4% of TEAs were outpatient, compared with 34.5% in 2017. The total complication rate trended toward being lower in the outpatient group, but this difference was not statistically significant (P = .08). CONCLUSIONS: There is a significant trend toward TEA being performed as an outpatient procedure, with more than one-third currently being performed in this manner. In our study, there was no difference in the complication rate between inpatient and outpatient TEAs; in fact, outpatient TEAs trended toward having a lower complication rate than inpatient TEAs. Taken together, the outpatient setting comprises an ever-increasing segment of TEA without an increase in morbidity to patients.

Patient outcomes for the Internal Joint Stabilizer of the Elbow (IJS-E).

BACKGROUND: Recently, the Internal Joint Stabilizer of the Elbow (IJS-E) was developed as an internal dynamic fixator for use in the setting of traumatic elbow instability. This study reviews the patients who had an IJS-E placed at our institution. Specifically, postoperative complications, postoperative functional outcomes, and need for subsequent procedures were reviewed. METHODS: A retrospective chart review was conducted of patients in whom the IJS-E was implanted from June 2016 to July 2018. Indications for use, range of motion at final follow-up, and the need for subsequent procedures were reviewed. Disabilities of the Arm, Shoulder, and Hand (DASH) and Broberg-Morrey scores were also obtained. RESULTS: Ten IJS-E devices were implanted into 10 patients. Average length of follow-up was 13.4 months. Average flexion-extension and pronation-supination motion arcs at final follow-up were 106° and 141°, respectively. Seventy-eight percent of patients achieved >100° arcs of both flexion-extension and pronation-supination. Average DASH and Broberg-Morrey scores were 28.7 and 68.2, respectively. Four subsequent procedures were required in 4 patients: 2 contracture releases, 1 medial collateral ligament reconstruction, and 1 total elbow arthroplasty. There were no postoperative infections or nerve injuries. DISCUSSION: The IJS-E has replaced the use of external hinged fixation at our institution. Final range of motion was consistent with that reported for terrible triad and complex elbow dislocation injuries. The IJS-E is a good option for use in patients with traumatic elbow instability, as it restores motion and function without immediate postoperative complication. However, it does not eliminate the potential for future operative intervention in these complex injuries.

Isolated Distal Ulna Fracture With Distal Radioulnar Joint Dislocation: A Novel Fracture Pattern.

Background: Galeazzi fractures composed of a middle to distal third radius fracture with dislocation and/or instability at the distal radioulnar joint (DRUJ) have been well described for decades. However, the inverse scenario has seldom if ever been described in the literature. Methods: We explore the case of a 25-year-old active patient who experienced a traumatic distal ulna fracture with dislocation of the DRUJ without a distal radius fracture. Results: It was successfully treated with open reduction and Kirschner wire fixation. The patient regained equivalent strength and range of motion compared with the contralateral uninjured extremity. Conclusion: We feel this patient's successful postoperative course can guide future treatment plans for orthopedic surgeons who encounter similar fractures.

Obesity Is Not a Predictor of Complications in Upper Extremity Surgery.

BACKGROUND: Obesity is an often-cited cause of surgical morbidity. As a result, many institutions have required screening prior to "clearing" obese individuals for surgery. However, it remains unclear whether such testing is warranted for obese patients prior to upper extremity procedures. This study reviews surgical outcomes to determine if obesity does predict operative morbidity following upper extremity surgery. METHODS: The National Surgical Quality Improvement Program was queried for 18 Current Procedural Terminology codes, representing upper extremity fracture and arthroplasty procedures. Patients' body mass index (BMI) and medical histories were examined as predictors for postoperative complications. Both individual and combined incidences of complications were compared between patients stratified as normal-weight (BMI < 30); obese (BMI 30-40); and morbidly obese (BMI> 40). RESULTS: A total of 8,477 patients were identified over the 5-year study period; 5,303 had a BMI <30, 2,565 a BMI of 30 to 40 and 585 a BMI >40. With the exception of postoperative blood transfusions, there were no significant increases in the incidence rates of any complication event as a function of BMI class. The overall incidence of complications was 2.70 % for BMI <30; 2.74 % for BMI 30 to 40; and 1.54 % for BMI >40. CONCLUSIONS: Obesity is not a reliable predictor of complications following upper extremity surgery. Thus, requiring preoperative screening for obese patients may constitute an unnecessary burden on medical resources. Further study is needed to identify specific demographics that might serve as more accurate predictors of poor outcomes in obese patients undergoing surgery of the upper extremity.

Retrospective Analysis of Geriatric Patients Undergoing Hip Fracture Surgery: Delaying Surgery Is Associated With Increased Morbidity, Mortality, and Length of Stay.

INTRODUCTION: Hip fractures are common in elderly patients. However, this population frequently presents with significant medical comorbidities requiring extensive medical optimization. METHODS: This study sought to elucidate optimal time to surgery and evaluate its effect on postoperative morbidity, mortality, and length of stay (LOS). We performed a retrospective analysis of data collected from 2008 to 2010 on 841 patients who underwent hip fracture surgery. Patients were classified based on time to surgery and were also classified and analyzed according to the American Society of Anesthesiologists (ASA) physical classification system. RESULTS: Patients with a delay of greater than 48 hours had a significant increase in overall LOS, postoperative days, and overall postoperative complications. Patients classified as ASA 4 had an odds ratio for postoperative morbidity of 3.32 compared to the ASA 1 and 2 group (P = .0002) and 2.26 compared to the ASA 3 group (P = .0005). Delaying surgery >48 hours was also associated with increased in-hospital mortality compared to 24 to 48 hours (P = .0197). Increasing ASA classification was also associated with significantly increased mortality. Patients classified as ASA 4 had 5.52 times the odds of ASA 1 and 2 (P = .0281) of in-hospital mortality. Those classified ASA 4 had 2.97 times the odds of ASA 3 (P = .0198) of an in-house mortality. Anesthetic technique (spinal vs general) and age were not confounding variables with respect to mortality or morbidity. DISCUSSION: Surgical timing and ASA classification were evaluated with regard to LOS, number postoperative days, morbidity, and mortality. CONCLUSIONS: Delaying surgery >48 hours, especially in those with increased ASA classification, is associated with an increase in overall LOS, postoperative days, morbidity, and mortality. However, rushing patients to surgery may not be beneficial and 24 to 48 hours of preoperative optimization may be advantageous.

Improvement in Sleep Quality after Carpal Tunnel Release.

Carpal tunnel syndrome (CTS) has multiple implications on patient quality of life. In particular, CTS may affect quality of sleep, causing sleep deprivation in extreme cases. Carpal tunnel release (CTR) surgery may aid in resolving these disturbances. The purpose of our study was to investigate whether patients who have undergone CTR have improved sleep quality and to determine the timeline for such improvement. Twenty-one patients were prospectively enrolled and followed-up for two years. They were asked to complete a Pittsburgh Sleep Quality Index (PSQI), a pain visual analog scale (VAS), a sleep perception VAS, and both components Symptom Severity and Functional Status Scale from the Levine-Katz carpal tunnel questionnaire. Patients had overall improvement in their postoperative outcome measures; however, the improvement in PSQI became significant at the 12-24 month follow-up, whereas both of the VAS scores significantly improved at an earlier 6 month follow-up. Both components of the Levine-Katz questionnaire significantly improved in the immediate postoperative period. Our findings allow surgeons to counsel their patients on realistic expectations after CTR and its impact on sleep quality.
