RESUMEN
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.
RESUMEN
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.

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.

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.

INTRODUCTION: Complication rates are used to evaluate surgical quality-of-care and determine health care reimbursements. The U.S. News & World Report (USNWR) hospital rankings are a highly-referenced source for top hospitals. The objective of this study was to determine the surgeon demographics of those practicing at USNWR Top Ranked Orthopedic Hospitals and if any influence complication rates after total knee arthroplasty (TKA). METHODS: The 2009-2013 USNWR 'Orthopedic' hospital rankings were identified. A database of TKA surgeons with postoperative complication rates was compiled utilizing publicly available data from the Centers for Medicare and Medicaid Services (2009-2013). Using an internet search algorithm, demographic data were collected for each surgeon and consisted of: fellowship training, years in practice, age, gender, practice setting, medical degree type, residency reputation, case volume, and geographic region of hospital. Logistic regression was used to assess the relationship between surgeon demographics and postoperative complication rates. A P value of < 0.008 was considered significant. RESULTS: From 2009 to 2013, 660 orthopedic surgeons performed TKA at 80 different USNWR Top-Ranked Hospitals. Mean TKA case volume was 172 (Range, 20-1323) and age of surgeon was 50.8 (Range, 32-77). A total of 372 (56.8%) completed an orthopedic surgery fellowship. Mean adjusted 30-day complication rate was 2.24% (Range, 1.2-4.5%). After adjustment, factors associated with increased complication rates were surgeon age ≤ 42 (OR 3.15; P = 0.007) and lower case volume (≤ 100 cases) (OR 2.52; P < 0.0001). Gender, hospital geographic region, completion of a fellowship, medical degree type, and residency reputation were not significant factors. DISCUSSION: Complication rates of total knee arthroplasty surgeons may be utilized by patients and hospitals to gauge quality of care. Certain surgeon factors may influence complication rates of surgeons performing TKA at USNWR Top Ranked Orthopedic Hospitals. STUDY TYPE: Level III, retrospective observational study.
RESUMEN
PURPOSE: Alcohol use disorder is a leading mental health disorder in the United States. Few studies evaluating the association of alcohol use disorder following primary total hip arthroplasty (THA) have been reported. Therefore, the purpose of this study was to determine whether patients with alcohol use disorder undergoing primary THA have higher rates of: 1) in-hospital lengths of stay (LOS); 2) complications (medical/implant-related); and 3) costs. MATERIALS AND METHODS: Using a nationwide claims database from January 1st, 2005 to March 31st, 2014, patients with alcohol use disorder undergoing primary THA were identified and matched to a comparison group according to age, sex, and various comorbidities, resulting in 230,467 patients who were included in the study (n=38,416) and a matched-cohort (n=192,051). Outcomes of interest included comparison of LOS, 90-day medical and 2-year implant-related complications, and costs. A P-value less than 0.002 was considered statistically significant. RESULTS: Patients with alcohol use disorder had longer in-hospital LOS (4 days vs 3 days; P<0.0001) as well as higher frequency and odds ratio (OR) of 90-day medical (45.94% vs 12.25%; OR, 2.89; P<0.0001) and 2-year implant-related complications (17.71% vs 8.46%; OR, 1.97; P<0.0001). Patients in the study group incurred higher 90-day costs of care ($17,492.63 vs $14,921.88; P<0.0001). CONCLUSION: With the growing prevalence of alcohol use disorder in the United States, the current investigation can be utilized to evaluate the need for interventions prior to THA which can potentially minimize the rates of morbidity and mortality within this population.
RESUMEN
This study includes three patients with various peripheral neuropathies after contracting coronavirus disease 2019 (COVID-19) infection, treated both conservatively and surgically. While cases of neurological complications have been described, neuropathy associated with COVID-19 is under-reported in orthopaedic literature. These patients presented with ulnar neuropathy, critical care polyneuropathy (CCP) with anterior interosseous nerve (AIN) neuropathy, and lateral femoral cutaneous nerve (LFCN) neuropathy. COVID-19 infection may be associated with peripheral neuropathy in addition to various neurological sequelae. Orthopaedic surgeons should screen patients for recent infections and evaluate the severity of the illness to assess for risk of neurological sequelae of COVID-19 infection.
RESUMEN
INTRODUCTION: Risk factors associated with primary THA readmissions have not yet been thoroughly analyzed when stratified by underlying indication. Given that a majority of THAs are done electively in the context of osteoarthritis (OA), it remains to be explored whether or not THAs performed non-electively in the trauma setting have different readmission patterns. Therefore, the aims of this study were to identify: 1) causes of readmissions; 2) patient-related risk-factors for readmissions; and 3) costs associated with the reasons for readmissions. MATERIALS AND METHODS: Patients who sustained a femoral neck fracture and underwent primary THA from 2005 to 2014 were identified. Those subsequently readmitted within 90-days following the procedure comprised the study cohort whereas those not readmitted served as the comparison cohort. Primary outcomes included identifying causes of readmissions, identifying patient-related risk-factors associated with readmissions and determining healthcare expenditures associated with the different readmission etiologies. A regression analysis was used to calculate the odds (OR) for readmissions. A p-value less than 0.01 was considered to be statistically significant. RESULTS: The regression model demonstrated the greatest patient-related risk factors included: electrolyte and fluid disorders (OR: 1.80, p < 0.0001), morbid obesity (OR: 1.60, p < 0.0001), pathologic weight loss (OR: 1.58, p < 0.0001), congestive heart failure (OR: 1.41, p < 0.0001), were the leading risk factors for readmissions. Pulmonary-related causes ($42,357.71) of readmission were the leading driver of costs of care. CONCLUSION: Orthopaedic surgeons should identify and optimize pre-operative management of patient-related risk factors that increase readmissions following primary THA for femoral neck fractures. Additionally, pulmonary-related causes of readmission lead to the highest costs of care. LEVEL OF EVIDENCE: III.
RESUMEN
There is renewed interest in bicruciate retaining (BCR) total knee arthroplasty (TKA), which preserves anatomy and more closely replicates native kinematics, theoretically allowing for improved functional results when compared to posterior stabilized (PS) TKA or cruciate retaining (CR) TKA. The purpose of this study is to report early clinical and radiographic results for a novel BCR TKA design.

INTRODUCTION: The purpose of this study was to determine whether alcohol use disorder (AUD) patients undergoing reverse shoulder arthroplasty (RSA) have increased: 1) lengths of stay (LOS); 2) complications; and 3) costs. METHODS: The study identified 19,168 patients in the study (n = 3198) and control (n = 15,970) cohort. In-hospital LOS, 90-day complications, and costs were assessed. RESULTS: AUD patients had significantly longer LOS (3- vs. 2-days, p < 0.0001), higher9 0-day medical complications (49.59 vs. 14.81%; p < 0.0001), and 90-day costs of care ($18,763.25 vs. $16,035.49, p < 0.0001). CONCLUSIONS: The study is useful as it can allow healthcare professionals to adequately counsel these patients.
RESUMEN
OBJECTIVE: The purpose of this study was to examine the metabolic, lipolytic, and cardiovascular responses to supplementation with p-synephrine alone and in combination with caffeine during resistance exercise (RE). METHODS: Twelve healthy men performed a control RE protocol (6 × 10 repetitions of squats) and were randomly assigned (using a double-blind crossover design with random protocol sequencing) to a supplement sequence: p-synephrine (S; 100 mg), p-synephrine + caffeine (SCF; 100 mg of p-synephrine plus 100 mg of caffeine), or a placebo (P). Subjects reported to the lab at a standard time, consumed a supplement, sat quietly for 45 minutes, performed the RE protocol, and sat quietly for 30 minutes. Blood samples were collected at rest (T1), after sitting quietly for 45 minutes (T2), immediately following RE (T3), and 15 minutes (T4) and 30 minutes (T5) postexercise. Oxygen consumption (VO2) and heart rate (HR) data were collected throughout. RESULTS: Serum glycerol was significantly elevated at T2 only in S and SCF and T3 to T5 in all treatments. Nonesterified fatty acid (NEFA) concentrations did not differ between treatments. Plasma glucose was significantly elevated compared to T1 with highest area under the curve values seen in SCF. Mean VO2 and energy expenditure (EE) were significantly higher in S and SCF through 30 minutes postexercise. Fat oxidation rates favored S and SCF between 25 and 30 minutes postexercise. Mean HR during RE was significantly highest in SCF. CONCLUSIONS: Supplementation with S and SCF increases lipolysis primarily at rest and increases VO2, EE, and fat oxidation rates 30 minutes following RE. No HR changes were observed unless caffeine was added.

BACKGROUND: Little is known concerning the potential ergogenic effects of p-synephrine supplementation. Therefore, the purpose of the present study was to examine the effects of supplementation with p-synephrine alone and in combination with caffeine on free-weight resistance exercise performance. METHODS: Twelve healthy, college-aged men performed a control (CT) resistance exercise protocol consisting of 6 sets of squats for up to 10 repetitions per set using 80% of their one repetition-maximum (1RM) with 2 min of rest in between sets. Each subject was randomly assigned (in double-blind, balanced manner) to a treatment sequence consisting of use of 3 supplements: p-synephrine (S; 100 mg), p-synephrine + caffeine (SCF; 100 mg of p-synephrine plus 100 mg of caffeine), or a placebo (P). For each supplement treatment (separated by 1 week), subjects consumed the supplement for 3 days prior to each protocol and the morning of each protocol, and subsequently did not consume any supplements for 3 days following (i.e. wash-out period). On each protocol day, subjects reported to the lab at a standard time, consumed a supplement, sat quietly for 45 min, performed the resistance exercise protocol, and sat quietly for 30 min post exercise. Performance (repetition number, force, velocity and power), blood lactate, and ratings of perceived exertion (RPE) data were collected during each protocol. RESULTS: Supplements SCF and S produced a significantly (P < 0.05) greater number of repetitions performed than CT (by 11.0 ± 8.0%) and P (by 6.0 ± 7.0%) and a 10.6 ± 12.0% greater increase in volume load per protocol than CT and P. Most of the differences were seen during the last 3 sets. Mean power and velocity for all 6 sets were significantly higher in SCF compared to CT and P by ~6.2 ± 8.0%. No supplement effects were observed in RPE or blood lactate, and no adverse side effects were observed or reported. CONCLUSIONS: S and SCF augmented resistance exercise performance (total repetitions, volume load) without increasing blood lactate or RPE. The addition of caffeine in SCF increased mean power and velocity of squat performance. These results indicate supplementation with S and SCF can enhance local muscle endurance during resistance exercise.
