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
INTRODUCTION: Social determinants of health (SDOH) have previously been shown to impact orthopedic surgery outcomes. This study assessed whether greater socioeconomic disadvantage in patients undergoing hemiarthroplasty following femoral neck fracture was associated with differences in (1) medical complications, (2) emergency department (ED) utilization, (3) readmission rates, and (4) payments for care. METHODS: A US nationwide database was queried for hemiarthroplasties performed between 2010 and 2020. Area Deprivation Index (ADI), a validated measure of socioeconomic disadvantage reported on a scale of 0-100, was used to compare two cohorts of greater and lesser deprivation. Patients undergoing hemiarthroplasty from high ADI (95% +) were 1:1 propensity score matched to a comparison group of lower ADI (0-94%) while controlling for age, sex, and Elixhauser Comorbidity Index. This yielded 75,650 patients evenly distributed between the two cohorts. Outcomes studied were 90-day medical complications, ED utilizations, readmissions, and payments for care. Multivariate logistic regression models were utilized to calculate odds ratios (ORs) of the relationship between ADI and outcomes. p Values < 0.05 were significant. RESULTS: Patients of high ADI developed greater medical complications (46.74% vs. 44.97%; OR 1.05, p = 0.002), including surgical site infections (1.19% vs. 1.00%; OR 1.20, p = 0.011), cerebrovascular accidents (1.64% vs. 1.41%; OR 1.16, p = 0.012), and respiratory failures (2.27% vs. 2.02%; OR 1.13, p = 0.017) compared to patients from lower ADIs. Although comparable rates of ED visits (2.92% vs. 2.86%; OR 1.02, p = 0.579), patients from higher ADI were readmitted at diminished rates (10.57% vs. 11.06%; OR 0.95, p = 0.027). Payments were significantly higher on the day of surgery ($7,570 vs. $5,974, p < 0.0001), as well as within 90 days after surgery ($12,700 vs. $10,462, p < 0.0001). CONCLUSIONS: Socioeconomically disadvantaged patients experience increased 90-day medical complications and payments, similar ED utilizations, and decreased readmissions. These findings can be used to inform healthcare providers to minimize disparities in care. LEVEL OF EVIDENCE: III.

INTRODUCTION: The incidence of osteonecrosis of the femoral head is estimated at about 10 to 20,000 patients annually, and, when left untreated, 80% or more of cases progress to femoral head collapse. A series of joint-preserving procedures have been developed to prevent/delay the need for hip arthroplasty. The aim of this study was to provide a five-year update: (1) evaluating temporal trends of arthroplasty vs. joint-preservation techniques such as core decompression, bone grafting, osteotomies, and arthroscopy; (2) determining proportions of procedures in patients aged less than vs. over 50 years; and (3) quantifying rates of specific operative techniques. METHODS: A total of 10,334 patients diagnosed with osteonecrosis of the femoral head and having received hip surgery were identified from a nationwide database between 1 January 2010 and 31 December 2019, by using the International Classification of Disease, the Ninth/Tenth revision (ICD-9/10) codes. The percentage of patients managed by each operative procedure was calculated annually. To identify trends, patients were grouped by age under/over 50 years and divided into a joint-preserving and a non-joint-preserving (arthroplasty) group. Chi-squared tests were performed to compare the total number of procedures per year. RESULTS: Rates of arthroplasty far exceeded those for joint-preserving procedures. However, from 2015 to 2019, significantly more joint-preserving procedures were performed than in 2010 to 2014 (4.3% vs. 3.0%, P < 0.001). Significantly more joint-preserving procedures were performed in patients aged < 50 years relative to those ≥ 50 years (7.56% vs. 1.86%, P < 0.001). Overall, total hip arthroplasty was the most common procedure (9,814; 94.97%) relative to core decompression (331; 3.20%), hemiarthroplasty/resurfacing (102; 0.99%), bone grafting (48; 0.46%), and osteotomy (5; 0.05%). CONCLUSION: Management of patients who have osteonecrosis of the femoral head continues to be predominantly arthroplasty procedures, specifically, total hip arthroplasty. Our findings suggest a small, but significant trend toward increased joint-preserving procedures, especially in patients under 50 years. In particular, the proportion of patients receiving core decompression has increased significantly from 2015 to 2019 relative to prior years.
RESUMEN
PURPOSE: Clostridium difficile colitis is a serious complication in elderly patients undergoing surgery. The objectives of this study were: (1) to use a nationwide sample of patients to report the incidence and timing of C. difficile colitis in geriatric patients who underwent surgery for hip fractures, (2) to identify preoperative factors associated with developing C. difficile colitis and mortality. METHODS: This was a retrospective evaluation of the 2016-2019 ACS Targeted Hip Fracture database merged with the ACS-NSQIP database. Patients undergoing surgery for hip fracture were included. Outcomes studied were incidence, preoperative, and postoperative risk factors for occurrence of C. difficile infection and mortality. Chi-squared tests were used to compare demographics between the patients infected (study) and not infected (control). Logistic regression models were utilized to compute the odds ratios (OR) testing for the association of independent factors on developing C. difficile infection postoperatively and mortality. A statistical threshold was set at p < 0.008. RESULTS: The incidence of C. difficile infection within 30 days of hip fracture surgery was 0.81%. Fifty percent of infections were diagnosed within 9 days postoperatively. Preoperative and hospital-associated factors associated with development of C. difficile infection were ≥ 2 days until operation (OR 1.88 [95% CI 1.39-2.55], p < 0.001) and dependent functional status (OR 1.43 [95% CI 1.14-1.79], p = 0.002). After adjusting for multiple comorbidities, increased age, male sex, COPD, CHF, dependent functional status, and C. difficile infection were associated with increased mortality within 30 days of surgery (all p < 0.001). CONCLUSION: Clostridium difficile colitis is a serious infection after hip fracture surgery in geriatric patients with an incidence of about 1%. Patients at increased risk should be targeted with preventative measures to prevent the morbidity from this complication.

INTRODUCTION: Studies evaluating the association of dementia in patients undergoing total hip arthroplasty (THA) for femoral neck fractures are limited. The aim was to investigate whether patients who have dementia undergoing THA for femoral neck fractures have higher rates of (1) in-hospital lengths of stay (LOS); 2) complications (medical and prostheses-related); and 3) healthcare expenditures. METHODS: A retrospective query using the PearlDiver database from January 1st, 2005 to March 31st, 2014 to identify patients with dementia undergoing primary total hip arthroplasty for the treatment of femoral neck fractures was performed. Dementia patients were 1:5 ratio matched to controls which yielded 22,758 patients in the study with (n = 3,798) and without (n = 18,960) dementia. Primary outcomes included comparing LOS, complications, and costs. A logistic regression was constructed to calculate the odds-ratios (OR) of dementia on complications. A p-value less than 0.004 was significant. RESULTS: Dementia patients had longer LOS (7-days vs. 6-days, p < 0.0001) and higher incidence and odds of medical complications (41.52 vs. 17.77%; OR 3.76, p < 0.0001), including cerebrovascular events (5.66 vs. 1.64%; OR 2.35, p < 0.0001), pneumoniae (9.98 vs. 3.82%; OR 1.82, p < 0.0001), and acute kidney injury (8.37 vs. 3.27%; OR 1.62, p < 0.0001). Study group patients had higher frequency of prostheses-related complications (9.53 vs. 8.31%; OR: 1.16, p = 0.012). The study group had greater total healthcare expenditures ($28,879.57 vs. $26,234.10, p < 0.0001) when analyzing ninety-day episode of care charges. CONCLUSION: Patients with dementia undergoing THA due to femoral neck fracture have increased LOS, medical and prostheses-related complications, and cost of care compared to their counterparts.

INTRODUCTION: Contemporary studies evaluating utilization and trends of total ankle arthroplasty (TAA) and ankle fusion (AF) for tibiotalar osteoarthritis are sparse. Therefore, the purpose of this study was to utilize a nationwide administrative claims database from 2010 to 2019 to compare: (1) baseline demographics; (2) utilization, (3) in-hospital length of stay (LOS), and (4) costs of care. METHODS: Using the PearlDiver database, a retrospective query from January 1st, 2010 to December 31st, 2019 was performed for all patients who underwent TAA and AF for tibiotalar osteoarthritis. Baseline demographics, comorbidities, and geographic utilization were compared using Pearson Chi-square analyses. Linear regression was used to compare differences in procedure utilization and in-hospital LOS during the study interval. Reimbursements between the two cohorts during the study interval were compared. A p value less than 0.05 was statistically significant. RESULTS: In total, 14,248 patients underwent primary TAA (n = 5544) or AF (n = 8704). Patients undergoing AF were generally younger (< 60) with greater comorbidity burden driven by hypertension, diabetes mellitus, obesity, and tobacco use compared to TAA patients (p < 0.0001). Over the study interval, TAA utilization remained constant (912 vs 909 procedures; p = 0.807), whereas AF utilization decreased by 42.5% (1737 vs 998 procedures; p = 0.0001). Mean in-hospital LOS for patients undergoing TAA decreased (2.5 days vs. 2.0 days, p = 0.0004), while AF LOS increased (2.6 days vs. 3.5 days, p = 0.0003). Reimbursements for both procedures significantly declined over the study interval (TAA: $4559-$2156, AF: $4729-$1721; p < 0.013). CONCLUSION: TAA utilization remained constant, while AF utilization declined by 42.5% from 2010 to 2019. There was divergence in the LOS for TAA versus AF patients. Both procedures significantly declined by over 50% in reimbursements over the study interval.

BACKGROUND: Cross-sectional studies have demonstrated that the prevalence of sleep apnea (SA) to be increasing within the United States. While studies have shown the association of SA and its association on complications following elective orthopedic procedures, well-powered studies investigating its impact in a traumatic setting are limited. The purpose of this study was to determine whether SA patients undergoing primary total hip arthroplasty (THA) for femoral neck fractures have higher rates of: (1) hospital lengths of stay (LOS); (2) readmissions; (3) complications; and (4) healthcare expenditures. METHODS: The 100% Medicare Standard Analytical Files was queried from 2005 to 2014 for patients who sustained femoral neck fractures and were treated with primary THA. The study group consisted of patients with concomitant diagnoses of SA, whereas patients without SA served as controls. Study group patients were matched to controls in a 1:5 ratio by age, sex, and various comorbid conditions. Demographics of the cohorts were compared using Pearson's chi-squared analyses, and multivariate logistic regression analyses were used to calculate the odds (OR) of the effects of SA on postoperative outcomes. A p value less than 0.006 was considered to be statistically significant. RESULTS: The final query yielded 24,936 patients within the study (n = 4166) and control (n = 20,770) cohorts. SA patients had significantly longer in-hospital LOS (6 vs. 5 days, p < 0.0001) but similar readmission rates (24.12 vs. 20.50%; OR: 1.03, p = 0.476). SA patients had significantly higher frequency and odds of developing medical complications (72.66 vs. 43.85%; OR: 1.57, p < 0.0001), and higher healthcare costs ($22,743.79 vs. $21,572.89, p < 0.0001). CONCLUSION: SA is associated with longer in-hospital LOS, higher rates of complications and healthcare expenditures. This study is vital as it can allow orthopaedists to educate patients with SA on the potential complications which may occur following their procedure. LEVEL OF EVIDENCE: III.

STUDY DESIGN: Retrospective study. OBJECTIVE: To determine whether opioid use disorder (OUD) patients undergoing 1- to 2-level anterior cervical discectomy and fusion (1-2ACDF) have higher rates of: 1) in-hospital lengths of stay (LOS); 2) readmissions; 3) complications; and 4) costs. METHODS: OUD patients undergoing primary 1-2ACDF were identified within the Medicare database and matched to a control cohort in a 1:5 ratio by age, sex, and medical comorbidities. The query yielded 80,683 patients who underwent 1-2 ACDF with (n = 13,448) and without (n = 67,235) OUD. Outcomes analyzed included in-hospital LOS, 90-day readmission rates, 90-day medical complications, and costs. Multivariate logistic regression analyses were used to calculate odds-ratios (OR) for medical complications and readmissions. Welch's t-test was used to test for significance for LOS and cost between the cohorts. An alpha value less than 0.002 was considered statistically significant. RESULTS: OUD patients were found to have significantly longer in-hospital LOS compared to their counterparts (3.41 vs. 2.23-days, P < .0001), in addition to higher frequency and odds of requiring readmissions (21.62 vs. 11.57%; OR: 1.38, P < .0001). Study group patients were found to have higher frequency and odds of developing medical complications (0.88 vs. 0.19%, OR: 2.80, P < .0001) and incurred higher episode of care costs ($20,399.62 vs. $16,812.14, P < .0001). CONCLUSION: The study can help to push orthopaedic surgeons in better managing OUD patients pre-operatively in terms of safe discontinuation and education of opioid drugs and their effects on complications, leading to more satisfactory outcomes.
RESUMEN
The literature has shown an increase in prevalence of Crohn's disease (CD) within the United States alongside a concomitant rise in primary total knee arthroplasty (TKA) procedures. As such, with these parallel increases, orthopaedic surgeons will invariably encounter CD patients requiring TKA. Limited studies exist evaluating the impact of this disease on patients undergoing the procedure; therefore, this study endeavors to determine whether CD patients undergoing primary TKA have higher rates of (1) in-hospital lengths of stay (LOS), (2) medical complications, and (3) episode of care (EOC) costs. To accomplish this, a nationwide database was queried from January 1, 2005 to March 31, 2014 to identify patients undergoing TKA. The study group, patients with CD, was randomly matched to the controls, patients without CD, in a 1:5 ratio after accounting for age, sex, and medical comorbidities associated with CD. Patients consuming corticosteroids were excluded, as they are at risk of higher rates of adverse events following TKA. This query ultimately yielded a total of 96,213 patients, with 16,037 in the study cohort and 80,176 in the control one. The study compared in-hospital (LOS), 90-day medical complications, and day of surgery and total global 90-day EOC costs between CD and non-CD patients undergoing primary TKA. The results found CD patients undergoing primary TKA had significantly longer in-hospital LOS (4- vs. 3 days, p < 0.0001) compared with non-CD patients. CD patients were also found to have significantly higher incidence and odds of 90-day medical complications (25.31 vs. 10.75; odds ratio: 2.05, p < 0.0001) compared with their counterparts. Furthermore, CD patients were found to have significantly higher 90-day EOC costs ($15,401.63 vs. 14,241.15, p < 0.0001) compared with controls. This study demonstrated that, after adjusting for age, sex, and medical comorbidities, patients with CD have prolonged in-hospital LOS, increased medical complications, and higher EOC costs following primary TKA. Therefore, it establishes the importance for orthopaedists to adequately counsel CD patients of the potential complications and outcomes following their procedure.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: As of 2022, the Centers for Medicare and Medicaid Services does not provide nationwide coverage for cervical disc arthroplasty (CDA). The aim was to determine whether Medicare beneficiaries have differences in: (1) lengths of stay (LOS); (2) complications; (3) readmissions; and (4) costs of care. METHODS: Using the 2010 to 2020 PearlDiver database, we queried patients undergoing primary CDA for degenerative disc pathology. Study groups patients were those undergoing CDA with Medicare coverage (n = 1467); patients without Medicare coverage were the comparison cohort (n = 15,389). Endpoints were to compare demographics and comorbidities within the Elixhauser comorbidity index (ECI), LOS, 90-day complications, 90-day readmissions, and 90-day reimbursements. A multivariate logistic regression was used to calculate odds (OR) of medical complications and readmissions within 90-days. A P-value less than .003 was significant. RESULTS: Patients with Medicare coverage undergoing CDA had higher mean ECI compared to alternative payers (5.24 vs 3.26; P < .0001). Mean LOS was significantly higher for Medicare beneficiaries (2.20 vs 1.76 days; P < .010). There was no significant differences in odds of all medical complications (OR: 1.19, 95% CI: .98-1.44; P = .069) or readmission rates (1.77% vs 1.33%, OR:0.82, 95% CI: .50-1.29; P = .417) within 90-days following the index procedure among Medicare beneficiaries vs alternative payers. Non-Medicare beneficiaries had higher 90-day reimbursements compared to Medicare beneficiaries ($6,700 vs $7,086,P < .001). CONCLUSIONS: Medicare beneficiaries despite having slightly longer lengths of stay did not have higher rates of medical complications or readmissions. Surgeons and policy makers may use this data to consider alternative treatments in Medicare patients.
RESUMEN
OBJECTIVES: Despite lack of nationwide Medicare coverage by the Centers for Medicare and Medicaid Services, the utilization of cervical disc arthroplasty (CDA) has risen in popularity. The purpose was to compare primary and revision CDA from 2010 to 2020 with respect to: (1) utilization trends, (2) patient demographics, and (3) health care reimbursements. METHODS: Using the PearlDiver database, we studied patients undergoing primary and revision CDA for degenerative cervical spine pathology from 2010 to 2020. Endpoints of the study were to compare patient demographics (including Elixhauser Comorbidity Index [ECI]), annual utilization trends, length of stay (LOS), and reimbursements. Chi-square analyses compared patient demographics. t tests compared LOS and reimbursements. A linear regression was used to evaluate for trends in procedural volume over time. P values <0.05 were considered statistically significant. RESULTS: In total, 15,306 patients underwent primary (n = 14,711) or revision CDA (n = 595). Patients undergoing revisions had a greater comorbidity burden (mean ECI 4.16 vs. 2.91; P < 0.0001). From 2010 to 2020, primary CDA utilization increased by 413% (447 vs. 2297 procedures; P < 0.001); comparatively, revision CDA utilization increased by 141% (32 vs. 77 procedures; P < 0.001). Mean LOS was greater for revision cases (1.37 vs. 3.30 days, P < 0.001). Reimbursements for revisions were higher on the day of surgery ($5585 vs. $13,692) and within 90 days of surgery ($7031 vs. $19,340), all P < 0.0001. CONCLUSIONS: There is a high rate of annual growth in CDA utilization and revision CDA in the United States. Reimbursements for revision CDA were more than double primary cases.

INTRODUCTION: Sleep Apnea (SA) is a common sleep disorder that increases postoperative morbidity. There is limited research on how SA influences outcomes following operative fixation of ankle fractures. Therefore, the aim of this study was to determine whether patients who undergo surgical fixation for bimalleolar ankle fractures have higher rates of medical complications and health care expenditures. METHODS: A retrospective review from January 1, 2005 to March 31, 2014 was conducted using the parts A and B Medicare Data from PearlDiver database. Patients with and without SA on the day of the primary open reduction and internal fixation (ORIF) of their bimalleolar ankle fractures were queried using the International Classification of Diseases, Ninth Revision codes. Welch'st-tests were used to compare costs of care. A multivariate binomial logistic regression model was used to calculate the odds ratio (OR) of adverse events. A P-value <.001 was considered statistically significant. RESULTS: There were 20 560 patients (SA = 3150; comparison cohort = 17 410) who underwent ORIF for bimalleolar ankle fractures during the study period. Sleep apnea patients were found to have significantly higher rates and odds of 90-day medical complications (21.42% vs 7.47%, OR: 3.11, P < .0001) and 90-day costs of care ($7213.12 vs $5415.79, P < .0001). CONCLUSION: This research demonstrates an increased risk of postoperative medical complications and health care costs among patients with SA undergoing ORIF for bimalleolar ankle fractures. LEVEL OF EVIDENCE: Therapeutic, Level IV: Retrospective.
RESUMEN
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.

INTRODUCTION: While studies have shown favorable outcomes in the treatment of femoral neck fractures with the utilization of total hip arthroplasty (THA), adverse events, such as infections, can still occur. Therefore, the aims of this study were to 1) compare baseline demographics and 2) identify risk factors associated with developing either surgical site infections (SSIs) or peri-prosthetic joint infections (PJIs). MATERIALS AND METHODS: A retrospective analysis of patients who underwent primary THA for femoral neck fractures were queried from the Medicare database. The inclusion criteria consisted of patients developing SSIs within 90 days or PJIs within 3 years following the index procedure. The query yielded 2502 patients who developed infections in the form of either SSIs (n = 987) or PJIs (n = 1515) out of 57,191 patients treated for femoral neck fractures with primary THA. Primary endpoints were to compare baseline demographic profiles and determine risk factors associated with developing infections. Multivariate binomial logistic regression analyses were performed to determine the odds (OR) of developing infections. A p value less than 0.001 was considered to be statistically significant. RESULTS: Patients who developed either infections were found to be significantly different when compared to patients who did not develop infections. SSI (10 vs. 8, p < 0.0001) and PJI (9 vs. 5, p < 0.0001) patients both had significantly higher mean Elixhauser Comorbidity Index (ECI) scores compared to their counterparts. The regression model found the greatest risks for developing SSIs included hypertension (OR 1.63, p = 0.001), pathologic weight loss (OR 1.58, p < 0.0001), and iron deficiency anemia (IDA) (OR 1.48, p < 0.0001), whereas IDA (OR 2.14, p < 0.0001), pathologic weight loss (OR 1.75, p < 0.0001), and rheumatoid arthritis (OR 1.57, p < 0.0001) increased the odds for PJIs. CONCLUSION: This study can be utilized by orthopedic surgeons and other healthcare professionals to adequately educate these patients of the complications which may occur following their surgery.

INTRODUCTION: The World Health Organization (WHO) postulates that depressive disorders (DD) will be the leading cause of morbidity and mortality by 2030. Studies evaluating the association of DD following open reduction and internal fixation (ORIF) for the treatment of acetabular fractures are limited. Therefore, the purpose of this matched-control study was to determine whether DD patients undergoing ORIF for acetabular fractures have higher rates of: (1) in-hospital lengths of stay (LOS); (2) readmissions; (3) medical complications; and (4) costs of care. MATERIALS AND METHODS: A retrospective query from the 100% Medicare Standard Analytical Files (SAF) was performed to identify patients who underwent ORIF for acetabular fractures. The study group consisted of those patients with DD, whereas patients without the condition served as controls. Primary endpoints of the study were to compare in-hospital LOS, readmission rates, ninety-day medical complications, and costs of care. A p-value less than 0.01 was considered statistically significant. RESULTS: The query yielded 7084 patients within the study (ORIF = 1187, control = 5897). DD patients were found to have significantly longer in-hospital LOS (11 days vs. 10 days, p < 0.0001); however, odds (OR) of readmission rates were similar (23.16 vs. 18.68%; OR: 0.91, p = 0.26). Multivariate regression demonstrated DD to be associated with significantly higher (67.69 vs. 25.54%; OR: 2.64, p < 0.0001) 90-day medical complications. DD patients had significantly higher day of surgery ($30,505.93 vs. $28,424.85, p < 0.0001) and total global 90-day costs ($41,721.98 vs. $37,330.16, p < 0.0001) of care. CONCLUSION: After adjusting for covariates, DD is associated with longer in-hospital, complications, and costs of care in patients undergoing ORIF for the treatment of acetabular fractures, whereas readmission rates are similar. The study is vital as it can be used by orthopaedists and healthcare professionals to adequately educate these patients of the potential outcomes following their surgical procedure.

INTRODUCTION: Outpatient primary total hip arthroplasty (THA) accounts for approximately 8% of all total hip arthroplasties (THA) performed annually in the United States. As of 2020, Medicare removed THA from its inpatient-only list, allowing reimbursement as an outpatient procedure. This study aimed to determine whether outpatient primary THA is a potential alternative to inpatient procedures by assessing: 1) 90-day postoperative complications; 2) readmission rates; and 3) total costs of care. MATERIALS AND METHODS: Using a national database, a matched case-control study was conducted of primary THAs performed between January 1, 2008 and March 31, 2018. Outpatient primary THAs were identified (n=10,463) and matched in a 1:5 ratio to inpatient primary THAs (n=52,306) for age, sex, and comorbidities. Outcomes assessed were 90-day medical complications, readmissions, and associated total costs of care. Baseline demographics were compared using Pearson's chi-squared analyses, with multivariate logistic regressions to calculate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Patients undergoing outpatient THA had fewer 90-day complications (9.3 vs. 11.9%; OR: 0.80, 95% CI: 0.74 to 0.87, p<0.0001) relative to the inpatient cohort. Ninety-day readmission rates between outpatient and inpatient THAs were similar (4.1 vs. 4.8%; OR: 0.92, 95% CI: 0.83 to 1.03, p=0.166). Ninety-day costs were significantly lower for the outpatient cohort ($2,650.00 vs. $19,299.00, p<0.0001). CONCLUSION: Our study includes a large sample size of outpatient primary THAs and is the first to provide data quantifying cost differences relative to inpatient THAs. Our results suggest, in certain populations, that outpatient primary THAs are a safe alternative to inpatient procedures with the potential to decrease healthcare costs.
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
INTRODUCTION: In the proper age group, there is evidence that total hip arthroplasty (THA) has superior outcomes for the treatment of acetabular fractures compared with open reduction and internal fixation. Studies comparing patient demographics and identifying risk factors for either surgical site infections (SSIs) or periprosthetic joint infections (PJIs) are limited. Therefore, the purpose of this study was to (1) compare baseline demographics of patients who did and did not develop infections and (2) identify risk factors associated with developing either SSIs or PJIs. METHODS: A retrospective study from 2005 to 2014 was done using a nationwide claims database. The inclusion criteria consisted of patients sustaining an acetabular fracture and treated with THA who developed either SSIs or PJIs within 90 days or 2 years, respectively, whereas patients not developing infections served as control subjects. The final study yielded 13,059 patients within the study (n = 988) and control cohort (n = 12,071). Baseline demographics were compared. A multivariate regression model calculated the odds ratio (OR) associated with development of infections. P value less than 0.002 was considered statistically significant. RESULTS: The study demonstrated significant differences among the cohorts regarding baseline demographics. The greatest risk factors for SSIs within 90 days were morbid obesity (OR: 1.84, P < 0.0001), pathologic weight loss (OR: 1.64, P < 0.0001), and iron deficiency anemia (OR: 1.59, P = 0.001). An increased risk of PJIs was associated with iron deficiency anemia (OR: 1.97, P < 0.0001), pathologic weight loss (OR: 1.72, P < 0.0001), and morbid obesity (OR: 1.70, P = 0.0001). CONCLUSION: This study found notable differences between baseline demographics of the cohorts and a myriad of risk factors associated with developing infections after THA for acetabular fractures. This study provides insight into orthopaedic surgeons and other healthcare professionals on the need of properly educating these high-risk patients of the potential consequences which they may encounter after their procedure. LEVEL OF EVIDENCE: Level III.

A Tinel's sign, a percussion-induced, painful sensation, has been reported as the most useful sign for diagnosing a schwannoma. On magnetic resonance imaging, schwannomas often exhibit a split fat sign and a target sign. The typical treatment for schwannomas is surgical excision; however, excision often results in high rates of neurological deficit. The authors retrospectively reviewed 20 patients who underwent excision of a schwannoma from 2007 to 2015. Twenty patients presented with a split fat sign and 12 patients presented with a Tinel's sign on magnetic resonance imaging. Only 3 patients presented with a target sign on magnetic resonance imaging. The operative approach involved removing the schwannoma, preserving the nearby nerve fascicles, and leaving the epineurium open. Follow-up ranged from 3 to 91 months (average, 29 months). At final follow-up, all patients were pain free. Nineteen patients had normal sensation and full function of their affected limb. One patient developed postoperative posterior interosseous nerve palsy. A Tinel's sign, preoperative pain, and a split fat sign on preoperative magnetic resonance imaging are the clinical symptoms most useful for diagnosing a schwannoma. Schwannomas can be safely removed via intracapsular surgical excision with minimal complications, yielding eradication of preoperative pain, normal sensation, and full function.

A 15-year-old boy presented with a mass in his right arm after suffering a minor injury playing baseball. He had been diagnosed with a hematoma. There was no other outstanding medical/surgical history. Magnetic resonance images showed a heterogeneous mass arising from the brachialis muscle that mainly enhanced peripherally with extremely scant internal nodular enhancement. Core needle biopsy cells were positive for CD31 and CD34, markers for atypical endothelial cells, as well as MIB-1 and p53. The final diagnosis was an angiosarcoma of the brachialis muscle. Pediatric angiosarcoma, particularly within deep tissue, is exceedingly rare. Histological and immunohistochemical modalities led to the diagnosis. Magnetic resonance images suggested a mass with a large cystic/hemorrhagic space that could have been misconstrued as a hematoma had there been absolutely no nodular or septal enhancement. The patient underwent neoadjuvant chemotherapy and radiation before undergoing limb-sparing surgery that included resection of the mass with the brachialis muscle and short head of the biceps muscle. Neoadjuvant treatment was deemed successful due to a drastic reduction in the size of the tumor and 95% tumor necrosis. The patient was disease free 2 years postoperatively. There had been no local/systemic recurrences. He was pain free, had normal elbow function, and had returned to playing baseball. It is important to be extremely suspicious when a patient presents with a hemorrhagic, painless, enlarging mass after sustaining minor trauma. A careful and meticulous biopsy must be completed to achieve the correct diagnosis. Magnetic resonance imaging with gadolinium is recommended for evaluation because these masses can be often misinterpreted as hematomas. [Orthopedics. 2016; 39(3):e545-e548.].
