RESUMO
The purpose of this study was to determine if short-term outcomes differed for pediatric patients with suspected musculoskeletal infection with or without a preoperative MRI. This was a multicenter, retrospective review of patients aged 0-16 years who presented with atraumatic extremity pain, underwent irrigation and debridement (I&D), and received at least one preoperative or postoperative MRI over a 10-year period. Primary outcomes were time to OR, total I&Ds, readmission rate, time from OR to discharge, and total number of MRIs. Secondary outcomes entailed the rate at which concurrent osteomyelitis was identified in patients with septic arthritis and the extent of the resulting surgical debridement. Of the 104 patients, 72.1% had a preoperative MRI. Patients with a preoperative MRI were significantly less likely to have surgery on the day of admission. No difference was found between groups regarding total I&Ds, readmission rate, time from OR to discharge, and total number of MRIs. Of the 57 patients diagnosed with septic arthritis, those with a preoperative MRI were significantly more likely to have concurrent osteomyelitis identified and to undergo bony debridement in addition to arthrotomy of the joint. In conclusion, patient outcomes are not adversely affected by obtaining a preoperative MRI despite the delay in time to OR. Although preoperative MRI can be beneficial in ruling out other pathologies and identifying the extent of concurrent osteomyelitis, the decision to obtain a preoperative MRI and timing of surgery should be left to the discretion of the treating surgeon.
RESUMO
Background: A recently proposed risk factor for periprosthetic joint infections (PJI) in men is benign prostatic hyperplasia (BPH). The objective was to explore the association of BPH on 1) 90-day complications, 2) length of stay (LOS), 3) readmission rates, and 4) healthcare expenditures following total shoulder arthroplasty (TSA). Methods: A retrospective query was performed using a nationwide claims database from January 2005 to March 2014 for male patients undergoing primary TSA. The study cohort included 5067 patients with BPH while 50,720 patients served as the comparison cohort. Logistic regression determined the association of BPH on complications and readmissions. A p value less than 0.001 was significant. Results: Patients with BPH had higher incidence and odds (36.8 vs. 6.2%; OR: 2.73, p < 0.0001) of all ninety-day medical complications including PJIs (0.49 vs. 0.32%; OR: 1.54, p < 0.001). BPH patients had longer in-hospital LOS (3- vs. 2-days, p < 0.0001). Study group patients had higher 90-day episode of care reimbursements ($13,653 vs. $12,688), p < 0.0001). Conclusions: BPH is associated with increased complications and healthcare expenditures following total shoulder arthroplasty. The investigation can be used to educate BPH patients of the possible adverse events which may occur within ninety-days following primary TSA for the treatment of glenohumeral osteoarthritis.
RESUMO
CASE: A 17-year-old adolescent boy presented 2 months after initial intramedullary nail (IMN) fixation of a comminuted subtrochanteric fracture with refracture at the previous site and approximately 20° varus angulation of the nail. The bent femoral nail was successfully extracted using an open technique using Lohman bone-holding clamps and a broad plate. At the 1-year follow-up, fracture union was achieved. CONCLUSIONS: Removal of a deformed IMN is rare. No standardized protocol exists in guiding orthopaedic surgeons. A thorough review of techniques is discussed on this unusual complication.

Introduction: Studies evaluating utilization and trends of total ankle arthroplasty (TAA) and ankle fusion (AF) are sparse. The purpose of this study was to use a nationwide administrative claims database to compare baseline demographics between TAA and ankle arthrodesis and to determine whether patients who had a TAA have increased rates of: (1) utilization, (2) in-hospital length of stay (LOS), and (3) costs of care. Methods: PearlDiver, a nationwide claims database was queried from 2005 to December 2013 for all patients who underwent primary TAA or AF for the treatment of osteoarthritis of the ankle and foot. Baseline demographics of age, sex, geographic distribution, and the prevalence of comorbidities comprising the Elixhauser comorbidity index (ECI) were compared between patients who had TAA and AF. Linear regression was used to compare differences in utilization and in-hospital LOS between the 2 cohorts during the study interval. Annual charges and reimbursement rates for TAA were assessed during the study period. A P value less than .05 was considered to be statistically significant. Results: A total of 21 433 patients undergoing primary TAA (n = 7126) and AF (n = 14 307) were included. Patients undergoing TAA had significantly greater ECI driven by arrythmias, congestive heart failure, diabetes mellitus, electrolyte/fluid disorders, iron deficiency anemia than patients undergoing AF (P < .001). From 2005 to 2013, TAA utilization increased from 21.5% to 49.4% of procedures (P < .0001). There was reduced in-hospital LOS over the time interval for patients with TAA compared with AF (2.15 days vs. 3.11 days, P < .0001). Total ankle arthroplasty reimbursements remained stable while charges per patient increased significantly from $40 203.48 in 2005 to doubling by the end of 2013 to $86 208.59 (P < .0001). Conclusion: This study demonstrated increased use of TAA compared to AF showing decreased in-hospital LOS and increased cost of care with stagnant reimbursement rates.Level of Evidence: Level III.

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.

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.
RESUMO
BACKGROUND: The Elixhauser Comorbidity Index (ECI) is a stratification tool to predict adverse surgical outcomes. No studies have explored the relationship between ECI and outcomes following primary 1- to 2-level lumbar fusion (1-2LF). The purpose was to determine whether an ECI score greater than 1 correlated with (1) longer in-hospital length of stay (LOS) and (2) greater odds of developing 90-day medical complications. METHODS: A retrospective review from 2004 to 2015 was performed using the Medicare Standard Analytical Files for patients undergoing primary LF. Patients with ECI scores from 2 to 5 served as the study cohorts (1 for each ECI score), and patients with an ECI score of 1 served as the control cohort. In-hospital LOS and 90-day medical complications were compared between cohorts. A P value of <0.001 was statistically significant. RESULTS: A total of 105,120 patients were equally distributed between the 5 cohorts. Patients with an ECI score of 2 (6.00 ± 4.51), ECI 3 (6.22 ± 4.67), ECI 4 (7.35 ± 5.05), or ECI 5 (8.99 ± 5.67) had longer in-hospital LOS compared with patients with an ECI score of 1 (4.28 ± 4.36) (all P < 0.001). Patients with an ECI score of 2 (OR: 1.17, 95% CI: 1.05-1.30, P = 0.003; 2.85% vs 2.45%), ECI 3 (OR: 1.22, 95% CI: 1.10-1.36, P < 0.001; 2.98% vs 2.45%), ECI 4 (OR: 1.26, 95% CI: 1.13-1.40, P < 0.001; 3.10% vs 2.45%), or ECI 5 (OR: 1.18, 95% CI: 1.06-1.31, P = 0.001; 2.89% vs 2.45%) had greater incidence and odds of 90-day medical complications such as pneumonia, deep vein thrombosis, cerebrovascular accidents, and myocardial infarctions than patients in the control group (all P < 0.0001). CONCLUSIONS: Increasing ECI score was associated with longer in-hospital LOS and increased 90-day medical complication rates following 1-2LF. This study is the first to establish a correlation between ECI score, in-hospital LOS, and complication rates following lumbar fusion. CLINICAL RELEVANCE: ECI score may assist physicians in adjusting pre- and postoperative care for complex patients undergoing 1-2LF.
RESUMO
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.
RESUMO
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.
RESUMO
BACKGROUND: Research focused on the association of opioid use disorder (OUD) on postoperative outcomes in patients undergoing primary lumbar laminectomy is lacking. This study aims to observe the impact of OUD on (1) hospital length of stay (LOS), (2) readmission rates, (3) medical complications, and (4) health care expenditures. METHODS: A retrospective query was performed using a nationwide claims database from January 2005 to March 2014 for all patients who underwent lumbar laminectomy, yielding a total of 131,635 patients. The study cohort included 3515 patients with OUD, while 128,120 patients served as the comparison cohort. Multivariate binomial logistic regression analyses were used to determine the association of OUD on readmission rates and medical complications, whereas Welch's t tests were used to compare LOS and health care expenditures. A P value less than 0.001 was considered statistically significant. RESULTS: Patients with OUD undergoing lumbar laminectomy had significantly longer hospital LOS (3.68 vs 1.13 days, P < 0.0001). Readmission rates were significantly higher (14.57% vs 7.39%, OR: 1.73, P < 0.0001) in patients who had an OUD. The study cohort was found to have higher incidence and odds (32.36% vs 9.76%, OR: 3.53, P < 0.0001) of 90-day medical complications and total global 90-day episode of care reimbursement rates ($13,635.81 vs $8131.20, P < 0.0001) compared with their counterparts. CONCLUSIONS: This study demonstrates OUD to be associated with longer hospital LOS, increased rates of 90-day readmissions, medical complications, and health care expenditures following lumbar laminectomy. CLINICAL RELEVANCE: Results indicate that OUD is associated with worse outcomes following lumbar laminectomy.
RESUMO
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.

BACKGROUND: As the incidence and prevalence of Crohn's disease continues to change worldwide, rates within North America have been increasing. The objective of this study was to evaluate whether patients who have Crohn's disease undergoing primary total hip arthroplasties have worse outcomes compared with matched cohorts. Specifically, we evaluated 1) medical complications, 2) in-hospital lengths of stay (LOS), and 3) costs of care. METHODS: Two cohorts of patients who underwent primary total hip arthroplasties from January 1, 2005 to March 31, 2014 were identified from the Medicare claims of the PearlDiver platform. Cohorts were matched by age, sex, and following comorbidities-anemia, diabetes, hyperlipidemia, hypertension, malnutrition, pulmonary disease, and renal failure, yielding 55,361 patients within the study (n = 9229) and matching cohorts (n = 46,132). Outcomes assessed included 90-day medical complications, in-hospital LOS, and costs of care. A P-value less than .005 was considered statistically significant. RESULTS: Patients with Crohn's disease were found to have significantly higher incidences and odds ratios of 90-day medical complications (30.2 vs 13.8; odds ratios: 2.2, P < .0001). They were also found to have significantly longer LOS (3.8- vs 3.6-days, P < .0001) and higher day of surgery ($12,662.00 vs 12,271.15, P < .0001) and 90-day episode costs ($16,933.18 vs $15,670.32, P < .0001). CONCLUSION: Crohn's disease is associated with higher rates of medical complications, longer in-hospital LOS, and increased costs of care. This study may aid physicians to perform appropriate risk adjustment for adverse outcomes and to educate these patients about potential postoperative complications in these patients.
