Sociopolitical, clinical, and ethical challenges of sustainable fracture care in Haiti.

INTRODUCTION: In low- and middle-income countries such as Haiti, musculoskeletal injuries are the leading cause of morbidity and mortality. Untreated injuries can contribute to decreased mobility, leading to disability and reduced productivity for individuals. The accessibility of timely fracture care poses a substantial challenge in Haiti, where socioeconomic instability and recent surges in gang violence exacerbate an already strained healthcare infrastructure. This manuscript delves into the intricate barriers to sustainable fracture care in Haiti, shedding light on the sociopolitical landscape and clinical challenges that influence the delivery of orthopedic services. ETHICAL DISCUSSION: The ethical considerations in providing fracture care in Haiti are multifaceted, including classic medical principles, self-preservation in the face of violence, issues of justice in resource and service allocation, and concerns of nonmaleficence in the context of international volunteers. These ethical dilemmas arise from the complex interplay of limited resources, the dangers posed by the current sociopolitical climate, and the involvement of international aid in a vulnerable healthcare system. CONCLUSION: To address the clinical and ethical conflicts of providing fracture care in Haiti, solutions include education and training of Haitian orthopedic surgeons, capacity building of healthcare facilities, and establishing ethical standards for international volunteers. This comprehensive approach is vital for advancing sustainable fracture care in Haiti and other resource-limited settings.

Exploring versatile applications of a vacuum-assisted bone harvester in orthopedic surgery.

BACKGROUND: Orthopedic procedures often require removing bone or pathological tissue, with traditional methods involving instruments like curettes and rongeurs. However, these methods can be time-consuming and lead to increased blood loss. To mitigate these side effects, vacuum-assisted tools have been developed to aid in tissue removal. These devices enable surgeons to suction tissue without discarding it, potentially improving outcomes in conditions such as osteomyelitis or tumor removal while enabling collection of the material for downstream applications. Despite limited research, vacuum-assisted devices show promise beyond bone marrow harvesting. This study assesses infection and clearance rates, estimated blood loss, and total procedure time associated with the use of vacuum-assisted tissue removal, with a goal to understand if these devices can be used for tissue removal across a variety of pathologic conditions. METHODS: A retrospective cohort study was conducted on patients undergoing orthopedic procedures with the Avitus® Bone Harvester repurposed from its original design from December 1, 2021, to July 1, 2023. Procedures were categorized into oncology, and debridement for infection cases. Infection cases were further categorized into those secondary to trauma and those involving primary infections (osteomyelitis and periprosthetic joint infection). Clinical variables, including demographics, intraoperative details, complications, and follow-up, were reviewed. Statistical analysis included descriptive statistics computed with R Studio. RESULTS: The study included 44 patients, with debridement for infection cases being the most common (primary infection: 45.5%; infection secondary to trauma: 18.1%), followed by oncology cases (36.4%). In all oncology cases, a definitive diagnosis was established using the device, and no post-operative infections were reported. The infection clearance rate was 85.0% for primary infection cases and 50.0% for cases of infection following trauma. Across the entire cohort, the average blood loss was 314.52 mL (sd: 486.74), and the average total procedure time was 160.93 min (sd: 91.07). The overall reoperation rate was 47.7%, with an unplanned reoperation rate of 11.4%. CONCLUSION: The vacuum-assisted bone harvester was effectively utilized in a wide range of debridement and curettage procedures across diverse orthopedic surgeries. In oncology cases, the device enabled effective tissue removal with comparable recurrence rates, demonstrating its potential to minimize contamination while preserving tissue for accurate diagnoses. Additionally, a high rate of osteomyelitis eradication was observed in debridement for primary infection cases (85%). Despite the relatively high reoperation rate of 47.7%, it is crucial to interpret this figure within the context of the varied reasons for reoperation. Many of these reoperations were planned as part of a staged approach to treatment or were unrelated to the device's performance. It is crucial to acknowledge that isolating the device's contribution to these results can be difficult. The utilization of the device should be guided by considerations of cost-effectiveness and patient-specific risk factors.

Leveraging Artificial Intelligence and Digital Health to Address Health-Related Social Needs and Optimize Risk-Based Value in Orthopaedic Surgery.

As the health care landscape evolves toward value-based care and emphasizes health-related social needs, the importance of developing health policies and digital health solutions that foster health equity and risk-based reimbursement strategies has grown. Orthopaedic surgery, catering to a diverse patient population but challenged by a lack of workforce diversity, encounters distinct opportunities and obstacles in adopting digital health technologies for delivering equitable, high-value care. The integration of health-related social needs into the emerging value-based care model and risk-based reimbursement policies is important. Furthermore, the potential of incorporating robust artificial intelligence governance and big data analytics to enhance patient outcomes and support orthopaedic surgeons in treating their patient populations should be studied. There are crucial considerations for creating comprehensive digital health platforms tailored for orthopaedic surgery, and the significance of specialty-specific advocacy and collaboration among clinicians, policymakers, and MedTech companies cannot be understated.

The impact of political partisanship, certificate of need, Medicaid expansion, and area deprivation index on total shoulder arthroplasty prices in the United States.

BACKGROUND: Recent mandates from the Center for Medicare and Medicaid Services require United States hospitals to disclose health care service pricing. Yet, there's a gap in understanding how state-level factors affect hospital service pricing, like total shoulder arthroplasty (TSA). Comprehending these influences can help policymakers and health care providers manage costs and improve care access for vulnerable populations. The purpose of this study was to examine the effect of state characteristics such as partisan lean, certificate of need (CON) status, and Medicaid expansion on TSA price. METHODS: TSA price data was extracted from the Turquoise Health Database using Current Procedural Terminology code 23472. State partisan lean was determined by evaluating each state during the 2020 election year for its legislature (both senate and house), governor, presidential vote, and Insurance Commissioner Affiliation, categorizing states as either "Republican-leaning" or "Democratic-leaning." CON status, Medicaid expansion, Area Deprivation Index (ADI), and population density information was obtained from publicly available sources. Multivariable regression models were used to assess the relationship between these factors and TSA price. RESULTS: The study included 2068 hospitals nationwide. The median (interquartile range) price of TSA across these hospitals was $12,607 ($9,185). In the multivariable analysis, hospitals in Republican-leaning states were associated with a significantly greater price of +$210 (P = .0151), while Medicaid expansion was also associated with greater price +$1,878 (P < .0001). CON status was associated with a significant reduction in TSA prices of -$2,880 (P < .0001). In North Carolina an ADI >85 was associated with a reduction in price (P = .0045), while urbanization designation did not significantly impact TSA price (P = .8457). CONCLUSION: This cross-sectional observational study found that Republican-leaning states and Medicaid expansion were associated with increased TSA prices, while an ADI >85 and CON laws were associated with reduced TSA prices.

Outcomes and complications of revision reverse shoulder arthroplasty after failed primary anatomic shoulder arthroplasty or hemiarthroplasty: a systematic review.

BACKGROUND: The purpose of this study is to systematically review the evidence in the literature to ascertain the functional outcomes, range of motion (ROM), and complication and reoperation rates after revision reverse shoulder arthroplasty (RSA) for a failed primary total shoulder arthroplasty (TSA) or hemiarthroplasty (HA). METHODS: Two independent reviewers performed the literature search based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using the EMBASE, MEDLINE, and The Cochrane Library databases. Studies were included if they reported clinical outcomes for revision RSA for a failed primary TSA or HA. RESULTS: Our review found 23 studies including 1041 shoulders (627 TSA and 414 HA) meeting our inclusion criteria. The majority of patients were female (66.1%), with an average age of 69.0 years (range: 39-93 years) and a mean follow-up of 46.3 months. American Shoulder and Elbow Surgeons and visual analog scale pain scores improved from 32.6 to 61.9 and 6.7 to 2.7, respectively. ROM results include forward flexion, abduction, and external rotation, which improved from 59.4° to 107.7°, 50.7° to 104.4°, and 19.8° to 26.3°, respectively. Only 1 of the 10 studies reporting internal rotation found a statistically significant difference, with the mean internal rotation improving from S1-S3 preoperatively to L4-L5 postoperatively for patients undergoing HA. The overall complication rate and reoperation rate were 23.4% and 12.5%, respectively. The most common complications were glenoid component loosening (6.0%), fracture (periprosthetic, intraoperative, or other scapula fractures) (n = 4.7%), and infection (n = 3.3%). CONCLUSIONS: Revision RSA for a failed primary TSA and HA has been shown to result in excellent functional outcomes and improved ROM, suggesting that patients who have failed TSA or HA may benefit from a revision RSA.

Health care policy and arthroscopic rotator cuff repair prices in the United States.

BACKGROUND: Arthroscopic rotator cuff repair (ARCR) is one of the most common orthopedic procedures in the general population. Despite its prevalence, the price of ARCR varies significantly across regions, hospital models, and settings. The purpose of this study was to examine the effect of Geographic Region, Certificate of Need (CON) laws, and Medicaid expansion on ARCR pricing. METHODS: This cross-sectional observational study used hospital payer-specific ARCR prices from the Turquoise Health Database using Current Procedural Terminology code 29827. These prices are negotiated rates or charges that hospitals establish with various payers, including insurance companies, Medicare, Medicaid, and self-pay patients, for medical services and treatments provided. Outliers below the 10th percentile and above the 90th percentile were excluded. State policies, including CON status and Medicaid expansion, were obtained from public sources, whereas additional socioeconomic and demographic data were sourced from the US Census. The state's region classification was determined based on 1 of 4 Geographic Regions defined by the US Census Bureau. A detailed analysis was also conducted for North Carolina, examining county-level data on urbanization and the Area Deprivation Index. RESULTS: There were 57,270 ARCR prices from 2503 hospitals across the United States, with a median interquartile range listed price of $6428.17 (interquartile range: $2886.88). States with CON regulations had significantly lower ARCR prices than those without ($6500 vs. $8000, P < .0001). Multivariable analysis indicated that hospitals in the Northeast and West Regions listed significantly higher prices for ARCR than those in the Midwest Region (P < .0001). In contrast, hospitals in the South Region listed lower prices for ARCR than those in the Midwest Region (P < .0001). Medicaid expansion was associated with increased ARCR prices (P < .0001), whereas CON laws were linked to reduced prices (P < .0001). In North Carolina, Area Deprivation Index and urbanization status did not significantly affect ARCR prices. CONCLUSION: The prices listed for ARCR varied significantly depending on the Geographic Region where hospitals were located. In addition, CON laws were associated with reduced ARCR prices, whereas Medicaid expansion correlated with increased prices. These findings highlight the complex interplay between health care policy, regulatory frameworks, and socioeconomic factors in determining surgical prices.

Prediction of 30-Day Mortality Following Revision Total Hip and Knee Arthroplasty: Machine Learning Algorithms Outperform CARDE-B, 5-Item, and 6-Item Modified Frailty Index Risk Scores.

BACKGROUND: Although risk calculators are used to prognosticate postoperative outcomes following revision total hip and knee arthroplasty (total joint arthroplasty [TJA]), machine learning (ML) based predictive tools have emerged as a promising alternative for improved risk stratification. This study aimed to compare the predictive ability of ML models for 30-day mortality following revision TJA to that of traditional risk-assessment indices such as the CARDE-B score (congestive heart failure, albumin (< 3.5 mg/dL), renal failure on dialysis, dependence for daily living, elderly (> 65 years of age), and body mass index (BMI) of < 25 kg/m2), 5-item modified frailty index (5MFI), and 6MFI. METHODS: Adult patients undergoing revision TJA between 2013 and 2020 were selected from the American College of Surgeons National Surgical Quality Improvement Program database and randomly split 80:20 to compose the training and validation cohorts. There were 3 ML models - extreme gradient boosting, random forest, and elastic-net penalized logistic regression (NEPLR) - that were developed and evaluated using discrimination, calibration metrics, and accuracy. The discrimination of CARDE-B, 5MFI, and 6MFI scores was assessed individually and compared to that of ML models. RESULTS: All models were equally accurate (Brier score = 0.005) and demonstrated outstanding discrimination with similar areas under the receiver operating characteristic curve (AUCs, extreme gradient boosting = 0.94, random forest = NEPLR = 0.93). The NEPLR was the best-calibrated model overall (slope = 0.54, intercept = -0.004). The CARDE-B had the highest discrimination among the scores (AUC = 0.89), followed by 6MFI (AUC = 0.80), and 5MFI (AUC = 0.68). Albumin < 3.5 mg/dL and BMI (< 30.15) were the most important predictors of 30-day mortality following revision TJA. CONCLUSIONS: The ML models outperform traditional risk-assessment indices in predicting postoperative 30-day mortality after revision TJA. Our findings highlight the utility of ML for risk stratification in a clinical setting. The identification of hypoalbuminemia and BMI as prognostic markers may allow patient-specific perioperative optimization strategies to improve outcomes following revision TJA.

Racial and Ethnic Disparities in Predictive Accuracy of Machine Learning Algorithms Developed Using a National Database for 30-Day Complications Following Total Joint Arthroplasty.

BACKGROUND: While predictive capabilities of machine learning (ML) algorithms for hip and knee total joint arthroplasty (TJA) have been demonstrated in previous studies, their performance in racial and ethnic minority patients has not been investigated. This study aimed to assess the performance of ML algorithms in predicting 30-day complications following TJA in racial and ethnic minority patients. METHODS: A total of 267,194 patients undergoing primary TJA between 2013 and 2020 were identified from a national outcomes database. The patient cohort was stratified according to race, with further sub-stratification into Hispanic or non-Hispanic ethnicity. There were two ML algorithms, histogram-based gradient boosting (HGB), and random forest (RF), that were modeled to predict 30-day complications following primary TJA in the overall population. They were subsequently assessed in each racial and ethnic subcohort using discrimination, calibration, accuracy, and potential clinical usefulness. RESULTS: Both models achieved excellent (Area under the curve (AUC) > 0.8) discrimination (AUCHGB = AUCRF = 0.86), calibration, and accuracy (HGB: slope = 1.00, intercept = -0.03, Brier score = 0.12; RF: slope = 0.97, intercept = 0.02, Brier score = 0.12) in the non-Hispanic White population (N = 224,073). Discrimination decreased in the White Hispanic (N = 10,429; AUC = 0.75 to 0.76), Black (N = 25,116; AUC = 0.77), Black Hispanic (N = 240; AUC = 0.78), Asian non-Hispanic (N = 4,809; AUC = 0.78 to 0.79), and overall (N = 267,194; AUC = 0.75 to 0.76) cohorts, but remained well-calibrated. We noted the poorest model discrimination (N = 1,870; AUC = 0.67 to 0.68) and calibration in the American-Indian cohort. CONCLUSION: The ML algorithms demonstrate an inferior predictive ability for 30-day complications following primary TJA in racial and ethnic minorities when trained on existing healthcare big data. This may be attributed to the disproportionate underrepresentation of minority groups within these databases, as demonstrated by the smaller sample sizes available to train the machine learning models. The ML models developed using smaller datasets (e.g., in racial and ethnic minorities) may not be as accurate as larger datasets, highlighting the need for equity-conscious model development.

The association of pre-existing mental health conditions and patient outcomes after lower extremity orthopaedic trauma: a scoping review.

INTRODUCTION: Existing research has established a correlation between post-traumatic mental health conditions, including anxiety and depression, and various aspects of recovery, such as pain exacerbations, reduced functional recovery, and lowered patient satisfaction. However, the influence of pre-existing mental health conditions on orthopaedic trauma outcomes has not been thoroughly investigated. The objective of this study was to systematically review literature addressing the association between pre-existing mental health conditions and patient outcomes following surgical interventions for lower extremity fractures in non-geriatric populations. METHODS: A systematic literature review was conducted using Medline, Embase, and Scopus databases following PRISMA-ScR guidelines to select studies that examined lower extremity orthopaedic trauma outcomes in relation to pre-existing mental health conditions. Studies that evaluated patients with surgically treated lower extremity fractures and a history of mental health conditions such as anxiety, depression, or mood disorders were included. Studies with a mean patient age above 65 years of age were excluded to focus on non-geriatric injury patterns. RESULTS: The systematic review identified 12 studies investigating the relationship between surgical outcomes of orthopaedic lower extremity fractures and pre-existing mental health disorders in non-geriatric populations. Studies included patients with pelvis, femur, tibia, and ankle fractures. A majority (83%) of these studies demonstrated that patients with pre-existing mental health diagnoses had inferior functional outcomes, heightened pain levels, or an increase in postoperative complications. DISCUSSION: The presence of pre-existing mental health conditions, particularly anxiety and depression, may predispose orthopaedic trauma patients to an elevated risk of suboptimal functional outcomes, increased pain, or complications after surgical intervention for lower extremity fractures. Future research should focus on interventions that mitigate the impact of mental health conditions on orthopaedic outcomes and patient wellness in this population.

Increasing Diversity in Orthopaedics: The Problem, Strategies, and Solutions.

It is important to educate and equip the orthopaedic community with tools to address health care disparities and improve orthopaedic specialty recruitment for racial minorities. How patients and providers are affected by systemic racism in healthcare and what that means in orthopaedic surgery, methods to identify bias and improve access to orthopaedic care for racial minorities, and how to structure a program and department environment to encourage and promote diversity are important topics of discussion.

Intramedullary nailing vs. open reduction-internal fixation for humeral shaft fractures: a meta-analysis of randomized controlled trials.

BACKGROUND: The purpose of this study was to perform a meta-analysis of randomized controlled trials (RCTs) to compare outcomes following intramedullary nailing (IMN) vs. open reduction-internal fixation (ORIF) for humeral shaft fractures. METHODS: A literature search of 3 databases was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. RCTs comparing IMN and ORIF for humeral shaft fractures were included. Clinical outcomes were compared using RevMan. P < .05 was considered statistically significant. RESULTS: Ten RCTs with 512 patients were included. Overall, 8.4% of patients treated with IMN and 6.4% of patients treated with ORIF had nonunion (P = .57, I2 = 0%), with a significantly faster time to union with IMN (10 weeks vs. 11.9 weeks, P < .05). There was no significant difference in the rate of reoperation (11.6% in IMN group vs. 7.6% in ORIF group, P = .26) or radial nerve palsy (2.8% in IMN group vs. 4.2% in ORIF group, P = .58). A lower rate of infection was noted with IMN (1.2% vs. 5.3%, P < .05). Additionally, there was a lower operative time with IMN (61 minutes vs. 88 minutes, P < .05). CONCLUSIONS: The Level I evidence in the literature does not show a significant difference in rates of union, reoperation, or radial nerve palsy between IMN and ORIF for humeral shaft fractures. Overall, treatment with IMN results in a lower infection rate, less operative time, and a modestly quicker time to union. The optimal treatment strategy for humeral shaft fractures may be best informed by fracture pattern and surgeon preference.

Shoulder arthroplasty device clearance: an ancestral network analysis.

BACKGROUND: The US Food and Drug Administration (FDA) oversees medical device regulation and oversight in the United States, and the majority of shoulder arthroplasty devices are cleared via the 510(k) pathway, in which a device demonstrates "substantial equivalence" to a previously cleared predicate. The purpose of this study was to determine an interconnected ancestral network of shoulder arthroplasty devices and determine equivalency ties to devices subsequently recalled by the FDA for design-related issues. METHODS: The FDA 510(k) database was used to identify all legally marketed shoulder arthroplasty devices from May 28, 1976, to July 1, 2021. Direct predicate information obtained via clearance summary documents associated with each device was used to generate an ancestral genealogy network for all shoulder arthroplasty devices cleared between July 1, 2020, and July 1, 2021. FDA design recalls were analyzed, and the number of descendant devices was calculated for each recalled device. RESULTS: An evaluation of all 476 510(k) premarket notification pathway-cleared shoulder devices since 1976 identified 0-313 descendant devices for each. Eighty of these devices (16.8%) have since been recalled, of which 10 recalls were directly related to implant design issues. Furthermore, among 29 of the most recently cleared devices (July 1, 2020-July 1, 2021), 16 (55.2%) claim predicates devices that have subsequently been withdrawn from the market because of design-related failures. CONCLUSIONS: Shoulder arthroplasty devices are linked together via an interconnected FDA 510(k) equivalency approval network dating back to 1976 despite substantive changes in material specifications and device design, many of which have since been recalled. Many of the cleared modern devices claim predicates based on subsequently recalled prostheses.

Association between radiographic soft-tissue thickness and increased length of stay, operative time, and infection rate after reverse shoulder arthroplasty.

BACKGROUND: Reverse shoulder arthroplasty (RSA) is a widely performed surgical procedure to address various shoulder pathologies. Several studies have suggested that radiographic soft-tissue thickness may play a role in predicting complications after orthopedic surgery, but there have been limited studies determining the use of radiographic soft-tissue thickness in RSA. The purpose of this study was to evaluate whether radiographic soft-tissue thickness could predict clinical outcomes after RSA and compare the predictive capabilities against body mass index (BMI). We hypothesized that increased radiographic shoulder soft-tissue thickness would be a strong predictor of operative time, length of stay (LOS), and infection in elective RSA. MATERIAL AND METHODS: A retrospective review of patients undergoing RSA at an academic institution was conducted. Preoperative radiographic images were evaluated including measurements of the radius from the humeral head center to the skin (HS), deltoid radius-to-humeral head radius ratio (DHR), deltoid size, and subcutaneous tissue size. Different correlation coefficients were used to analyze various types of relationships, and the strength of these associations was classified based on predefined boundaries. Subsequently, multivariable linear and logistic regressions were performed to determine whether HS, DHR, deltoid size, and subcutaneous tissue size could predict LOS, operative time, or infection while controlling for patient factors. RESULTS: HS was the most influential factor in predicting both operative time and LOS after RSA, with strong associations indicated by standardized ß coefficients of 0.234 for operative time and 0.432 for LOS. Subcutaneous tissue size, deltoid size, and DHR also showed stronger predictive values than BMI for both outcomes. In terms of prosthetic joint infection, HS, deltoid size, and DHR were significant predictors, with HS demonstrating the highest predictive power (Nagelkerke R2 = 0.44), whereas BMI did not show a statistically significant association with infection. Low event counts resulted in wide confidence intervals for odds ratios in the infection analysis. CONCLUSION: Greater shoulder soft-tissue thickness as measured with concentric circles on radiographs is a strong predictor of operative time, LOS, and postoperative infection in elective primary RSA patients.

Interfragmentary strain measurement post-fixation to guide intraoperative decision making: a narrative review.

PURPOSE: Interfragmentary strain influences whether a fracture will undergo direct and indirect fracture healing. Orthopedic trauma surgeons modulate strain and create optimal biomechanical environments for specific fracture patterns using fixation constructs. However, objective intraoperative interfragmentary strain measurement does not currently inform fixation strategy in common practice. This review identifies potential methods and technologies to enable intraoperative strain measurement for guiding optimal fracture fixation strategies. METHODS: PubMed, Scopus, and Web of Science were methodologically queried for manuscripts containing terms related to "bone fracture," "strain," "measurement," and "intraoperative." Manuscripts were systematically screened for relevance and adjudicated by three reviewers. Relevant articles describing methods to measure interfragmentary strain intraoperatively were summarized. RESULTS: After removing duplicates, 1404 records were screened initially. There were 49 manuscripts meeting criteria for in-depth review. Of these, four reports were included in this study that described methods applicable to measuring interfragmentary strain intraoperatively. Two of these reports described a method using instrumented staples, one described optical tracking of Kirschner wires, and one described using a digital linear variable displacement transducer with a custom external fixator. CONCLUSION: The four reports identified by this review describe potential methods to quantify interfragmentary strain after fixation. However, further studies are needed to confirm the precision and accuracy of these measurements across a range of fractures and fixation methods. Additionally, described methods require the insertion and likely removal of additional implants into the bone. Ideally, innovations that measure interfragmentary strain intraoperatively would provide dynamic biomechanical feedback for the surgeon to proactively modulate construct stability.

Scoring of radiographic cortical healing with the radiographic humerus union measurement predicts union in humeral shaft fractures.

PURPOSE: The purpose of this study is to determine if the radiographic humerus union measurement (RHUM) is predictive of union in humeral shaft fractures treated nonoperatively. METHODS: All patients with long bone fracture nonunion presenting to a single surgeon were enrolled in a prospective registry. This registry was queried to identify patients with humeral shaft fractures treated nonoperatively and developed nonunion. The nonunion cohort was matched to a three to one gender- and age-matched control group that were treated nonoperatively for a humeral shaft fracture and achieved union. Two fellowship-trained orthopedic traumatologists blinded to eventual union scored radiographs obtained 12 weeks after injury using the RHUM. A binomial logistic regression determined the effect of the RHUM on the likelihood of developing union. RESULTS: Nine patients with humeral shaft fractures treated nonoperatively with radiographs 12 weeks after injury that developed nonunion were identified. These patients were matched to 27 controls. Logistic regression demonstrated the RHUM was a significant predictor of healing 12 weeks after humeral shaft fracture treated nonoperatively (p = 0.014, odds ratio 9.434, 95% CI for OR 1.586-56.098). All patients with RHUM below 7 went on to nonunion. All patients with RHUM above 8 healed. Three of seven patients (43%) with RHUM of 7 or 8 healed. CONCLUSION: The RHUM demonstrated an increased likelihood of achieving union 12 weeks after injury. Orthopedic surgeons can counsel patients that fractures with RHUM scores of 6 or below are in danger of developing nonunion and can target interventions appropriately.

Shoulder Arthroscopy in Adults 60 or Older: Risk Factors That Correlate With Postoperative Complications in the First 30 Days.

PURPOSE: To investigate the 30-day postoperative adverse event (AE) rates of adults 60 years or older after shoulder arthroscopy and identify risk factors for complications in this patient population. METHODS: Patients aged 60 or more who underwent shoulder arthroscopy were identified in the American College of Surgeons National Surgery Quality Improvement Program database from 2006 to 2013 using 12 Current Procedural Terminology codes related to shoulder arthroscopy. Complications were categorized as severe AEs, minor AEs, and infectious AEs for separate analyses. Pearson's χ2 tests were used to identify associations between patient characteristics and AE occurrence and binary logistic regression for multivariate analysis of independent risk factors. RESULTS: In total, 7,867 patients were included for analysis. Overall, 1.6% (n = 127) of the older adults experienced at least one AE with 1.1% (n = 90) severe AEs, 0.6% (n = 46) minor AEs, and 0.4% (n = 28) infectious complications. Multivariate analysis revealed that age 80 years or older (odds ratio [OR] = 2.2, 95% confidence interval [CI] = 1.2-2.7, P = .01), body mass index greater than 35 (OR = 1.8, 95% CI = 1.1-2.7, P = .01), functionally dependent status (OR = 2.9, 95% CI = 1.3-6.8, P = .01), American Society of Anesthesiologists class greater than 2 (OR = 1.5, 95% CI = 1.0-2.2, P = .04), congestive heart failure (OR = 6.1, 95% CI = 1.8-21.2, P = .03), disseminated cancer (OR = 7.9, 95% CI = 1.4-43.9, P = .02), and existence of an open wound at the time of surgery (OR = 4.0, 95% CI = 1.1-14.6, P = .03) were independently associated with the occurrence of an AE. Nineteen of the patients included in the study required readmission to the hospital within the 30-day period for an overall readmission rate of 0.2%. CONCLUSIONS: Patients 60 years or older who underwent shoulder arthroscopy for a variety of indications have a low overall 30-day postoperative complication rate of 1.6%. Although low, this is a higher rate than previously reported for the overall shoulder arthroscopy population. Independent patient characteristics associated with increased risk of AE occurrence included age 80 years or older, body mass index greater than 35, functional dependent status, American Society of Anesthesiologists score of 3 or 4, congestive heart failure, disseminated cancer, and existence of an open wound. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Racial disparities in outcomes of operatively treated lower extremity fractures.

PURPOSE: Whether racial differences are associated with function in the long term following surgical repair of lower extremity fractures has not been investigated. The purpose of this study is to compare how race affects function at 3, 6 and 12 months post-surgery following certain lower extremity fractures. METHODS: Four hundred and eighteen patients treated operatively for a lower extremity fracture (199 tibial plateau, 39 tibial shaft, and 180 rotational ankle fractures) were prospectively followed for 1 year. Race was stratified into four groups: Caucasian, African-American, Hispanic origin, and other. Long-term outcomes were evaluated using the short musculoskeletal function assessment (SMFA) and pain scores were assessed at 3, 6 months and 1 year. RESULTS: There were 223 (53.3%) Caucasians, 72 (17.2%) African-Americans, 53 (12.4%) Hispanics, and 71 (17.0%) patients from other ethnic groups, included in our study population. Minority patients (African-American, Hispanics, etc.) were more likely to be involved in high velocity mechanisms of injury and tended to have a greater percentage of open fractures. Although there were no differences in the rate of wound complications or reoperations, long-term functional outcomes were worse in minority patients as assessed by pain scores at 6 months and functional outcome scores at 3, 6 and 12 months. Multivariate analysis revealed that only African-American and Hispanic race continued to be independent predictors of worse functional outcomes at 12 months. CONCLUSIONS: Racial minorities and those on medicaid had poorer long-term function following fractures of the lower extremity. While minority patients were involved in more high velocity accidents, this was not an independent predictor of worse outcomes. These disparities may result from multifactorial socioeconomic factors, including socioeconomic status and education levels that were not controlled in our study. LEVEL OF EVIDENCE: Prognostic Level III.

Outcome after olecranon fracture repair: Does construct type matter?

PURPOSE: This study compares clinical and functional outcomes of patients with displaced olecranon fractures treated with either tension band wiring (TBW) or a hook plate construct. METHODS: We performed a retrospective review of olecranon fractures operatively treated with either TBW or plate fixation (PF) using a hook plate over a 7-year period. Patient demographics, injury information, and surgical management were recorded. Fractures were classified according to the Mayo system. Measured outcomes included range of elbow motion, time to union, and development of postoperative complications. Mayo Elbow Performance Index (MEPI) scores were obtained for all patients. All patients were followed for a minimum of 6 months. RESULTS: A total of 48 patients were included in this study, 23 treated with TBW and 25 treated with hook PF. Groups did not differ with respect to patient demographics, Mayo fracture type, or duration of follow-up. Patients undergoing PF had less terminal extension than TBW patients (-8.6° ± 7° vs. -3.5° ± 9.3°, p = 0.036) and a longer time to radiographic union (19 ± 8 vs. 12 ± 6 weeks, p = 0.001). There were no differences in rates of symptomatic hardware, MEPI scores, or other clinical outcomes. Two patients in each group required a second surgery. CONCLUSIONS: TBW and PF of olecranon fractures had similarly excellent functional outcomes in this study. Patients undergoing PF had a longer time to union and slightly worse extension at final follow-up. TBW remains an effective treatment for appropriately selected olecranon fractures and in this cohort outperformed plate osteosynthesis.

Racial and Ethnic Disparities in Hip Fracture Surgery: A Systematic Review and Meta-Analysis.

Background: Hip fractures are common injuries that result in substantial loss of quality of life to elderly patients. To date, no meta-analyses have been performed to consolidate findings related to racial and ethnic disparities in hip fracture care. Purpose: We sought to examine associations between racial or ethnic identity and several metrics of hip fracture care. Methods: For a systematic review and meta-analysis, we searched PubMed, Scopus, CINAHL, and SPORTDiscus databases in December 2021 for articles examining racial and ethnic disparities in hip fracture surgery among White, Black, Hispanic, Asian, Pacific Islander (PI), and American Indian/Alaska Native (AIAN) patients. Twenty-three studies reported time to surgery (TTS), complications, mortality, length of stay (LOS), discharge disposition, readmissions, or reoperations. Meta-analyses were conducted for outcomes for which there were at least 3 comparable studies with requisite data available. Results: Compared with White patients, Black patients experienced greater rates of TTS longer than 2 days, 30-day complication, 90-day readmission, 1-year reoperation, and longer LOS, though odds of 30-day mortality were reduced. Hispanic patients had higher 90-day complication rates and longer LOS but lower risk of mortality and nonhome discharge than other racial and ethnic groups. Time to surgery of longer than 2 days was more common among Asian patients, though mortality, nonhome discharge, and readmission rates were lower. There were higher mortality rates in White patients compared with Hispanic patients at all timepoints and compared with Black patients until 1 year following surgery, when rates were higher among Black patients. Conclusions: This systematic review and meta-analysis found evidence of disparities in hip fracture surgery, with minority patients facing greater rates of surgical delay and perioperative complications. Even though the studies may not have been uniform in defining race or ethnicity or in accounting for the effects of systemic racism, these findings suggest that concerted efforts are needed to understand these gaps and promote equity in hip fracture care.

Persistent racial disparities in postoperative management after tibia fracture fixation: A matched analysis of US medicaid beneficiaries.

INTRODUCTION: Racial and ethnic disparities in orthopaedic surgery are well documented. However, the extent to which these persist in fracture care is unknown. This study sought to assess racial disparities in the postoperative surgical and medical management of patients after diaphyseal tibia fracture fixation. METHODS: Patients with surgically treated tibial shaft fractures from October 1, 2015, to December 31, 2020, were identified in the MarketScan® Medicaid Database. Exclusion criteria included concurrent fractures or amputation. Outcomes included 2-year postoperative complications, reoperation rates, and filled prescriptions. Surgically-treated Black and White cohorts were propensity-score matched using nearest-neighbor matching on patient demographics, comorbidities, fracture pattern and severity, and fixation type. Chi-square tests and survival analyses (Kaplan-Meier and Cox proportional hazard models) were conducted. RESULTS: 5,472 patients were included, 2,209 Black and 3,263 White patients. After matching, 2,209 were retained in each cohort. No significant differences in complication rates were observed in the matched Black vs White cohorts. Rates of reoperation, however, were significantly lower in Black as compared to White patients (28.5 % vs. 35.5 % rate, risk difference = 7.0 % (95 % confidence interval (CI): 4.2 % to 9.7 %)). Implant removal was also significantly lower in Black (17.9 %) vs. White (25.1 %) patients (Risk difference = 7.2 %, (95 %CI: 4.8 % to 9.6 %)). The adjusted hazard ratio comparing the reoperation rate in Black versus White patients was 0.77 (95 %CI: 0.69-0.82, p < 0.0001). Significantly lower proportions of Black vs White patients filled at least one prescription for benzodiazepine, antidepressants, strong opiates, or antibiotics at every time point post-index. DISCUSSION: Fewer resources were used in post-operative management after surgical treatment of tibial shaft fractures for Black versus White Medicaid-insured patients. These results may be reflective of the undertreatment of complications after tibia fracture surgery for Black patients and highlight the need for further interventions to address racial disparities in trauma care.
