Background: Although diversity has improved across certain orthopaedic subspecialties, enhancing diversity within spine surgery has remained a challenge. We aimed to investigate the current state of sex, racial, and ethnic diversity among academic orthopaedic spine surgeons in the United States.

Methods: In January 2024, a cross-sectional analysis of orthopaedic spine surgery faculty in the United States was conducted using the Doximity database to identify eligible surgeons. Fellowship-trained orthopaedic spine surgeons (professor, associate professor, and assistant professor) who graduated residency between 1990 and 2022 were included. Race, sex, academic rank, residency year of graduation, and H-Index scores were recorded using publicly available information from faculty profile pages and the Doximity database.

Results: Four hundred fifty-two spine faculty were included in the analysis: 95.1% men and 4.84% women. Across race and ethnicity, 315 surgeons (69.7%) were White, 111 (24.6%) Asian, 15 (3.32%) Black or African American, and 11 (2.43%) Hispanic or Latino or of Spanish origin. Of the 101 professor-level surgeons, 3 (2.97%) were Black men. Among female professors, none were Black, Asian, or Hispanic/Latino. No Hispanic or Latino female professors, associate professors, or assistant professors were identified. The sex and race/ethnicity demographics that have increased in percentage over time include White women (0.92% to 6.08%), Asian men (11.0% to 26.5%), Asian women (0% to 1.66%), and Hispanic/Latino men (1.83% to 3.87%). The surgeon demographic groups that demonstrated minimal fluctuations over time included Black men, Black women, and Hispanic/Latino women.

Conclusion: Our findings demonstrate that underrepresentation among academic spine surgeons remains an ongoing challenge that warrants increased attention. Enhancing the representation of Black and Hispanic men, as well as Black, Asian, and Hispanic women, in spine surgery requires a deliberate effort at every level of orthopaedic training.

Introduction: Distal tibia shaft fractures have a high association with posterior malleolar fractures (PMFs); hence, a preoperative ankle CT scan is commonly obtained. The purpose of this study was to determine whether a CT scan for distal third tibia shaft fractures is associated with differences in recognition of a posterior malleolus fracture (PMF), treatment of an identified PMF, outcomes, and postoperative complications.

Methods: We retrospectively reviewed cases of adult patients with distal third tibia shaft fractures treated with an intramedullary nail between 2018 and 2020. Patients were divided into 2 groups based on whether they received a preoperative ankle CT scan. Outcomes included surgical time, the rate of missed PMFs or postoperative PMF displacement, the treatment of the PMFs, postoperative weight-bearing restrictions, Patient-Reported Outcomes Measurement Information System Global-10 (PROMIS Global-10) scores, and unplanned revision surgeries.

Results: 124 patients (age 45 ± 18 years; 39.5% female) with distal third tibia shaft fractures treated with intramedullary nailing and with minimum 6 months of follow-up were reviewed. 26 patients received preoperative CT scans, and 98 patients did not have CT scans. The rate of detected PMF was 69.2% (N = 18) in patients with CT and 55.1% (N = 54) in patients without CT (P = 0.19). No significant differences were observed in all outcomes between the 2 groups (P > 0.05). 3 PMFs not visible on radiographs were identified on CT, and they did not require fixation and did not displace. PMFs that were greater than one-third of the joint surface were more likely to have a preoperative CT (P < 0.01).

Discussion: Preoperative CT scans for distal third tibia shaft fractures may be useful in characterizing large PMFs; however, this knowledge does not translate into shorter surgical time, increased fixation rates, decreased unplanned revision surgery, or improved patient-reported outcomes. Discovery of PMFs did not always lead to fixation, and PMFs without fixation did not become further displaced.

Symptomatic osteoarthritis (OA) of the first carpometacarpal (CMC) joint is prevalent and debilitating, commonly affecting the elderly and postmenopausal population. This review highlights the latest advancements in the treatment of thumb CMC OA, which historically includes a range of nonsurgical and surgical options without a consensus benchmark. We will focus on innovative and emerging technologies. Nonsurgical treatments typically comprise custom braces and corticosteroid injections. In addition, this review explores advanced approaches such as 3D printed braces, which have improved patient satisfaction, and novel intra-articular injectables such as autologous fat, optimized by ultrasonography to enhance treatment precision and outcomes. Although standard surgical treatments include trapeziectomy, with or without ligament reconstruction and tendon interposition, more recent implant arthroplasty designs show promising long-term survival. Newer interventions include patient-specific instrumentation for metacarpal osteotomies, selective joint denervation, and innovative suspensionplasty devices, all marked by their increased precision and personalized care. However, it is important to note that these novel technologies are not yet established as superior to standard treatments of thumb CMC OA.

Introduction: Spanish-speaking individuals may experience language-based disparities related to elective orthopaedic procedures. Because patients often seek online health information, we assessed the readability, credibility, and quality of Spanish-language educational websites for knee arthroplasty.

Methods: We queried "Google," "Yahoo," and "Bing" using the term "reemplazo de rodilla" (knee replacement in Spanish) and extracted the top 50 websites per search engine. Websites were categorized by information source (physician/community hospital, university/academic, other) and presence of HONcode certification. Information was assessed for readability (Fernández-Huerta formula), credibility (Journal of the American Medical Association benchmark criteria), and quality (Brief DISCERN tool); scores were compared between the categories.

Results: A total of 77 unique websites were included (40.3% physician/community hospital, 35.1% university/academic). The median readability score was 59.4 (10th to 12th-grade reading level); no websites achieved the recommended level of ≤6th grade. The median Journal of the American Medical Association benchmark score was 2 (interquartile range 1 to 3), with only 7.8% of websites meeting all criteria. The median Brief DISCERN score was 16 (interquartile range 12 to 20), with 50.7% meeting the threshold for good quality. University/academic websites had better readability (P = 0.02) and credibility (P = 0.002) but similar quality (P > 0.05) compared with physician/community hospital websites. In addition, HONcode-certified websites had better quality scores (P = 0.045) but similar readability and credibility (P > 0.05) compared with noncertified websites.

Discussion: We identified limitations in readability, credibility, and quality of Spanish-language online educational resources for knee arthroplasty. Healthcare providers should be aware of these patient education barriers when counseling patients, and efforts should be made to support the online information needs of Spanish-speaking orthopaedic patients and mitigate language-based disparities.

There is a general need among orthopaedic surgeons for practical advice on managing patients with bleeding disorders. Appropriate diagnosis and management of these disorders is paramount once discovered before, during, or after the patient's surgical course. Bleeding disorders disrupt the body's ability to control bleeding, commonly through platelet function and blood clotting. Normally, the vessel contracts and retracts once disruption of blood vessels occurs, limiting blood loss. Blood platelets adhere to exposed collagen, aggregate at the site, and obstruct blood loss. Because platelet aggregates are temporary, blood clotting is needed to back up the platelet plug and provide a milieu for the healing process that completes the hemostatic events. Disorders that interfere with any of these events can result in hemorrhage, drainage, or rebleeding. Bleeding disorders are a group of conditions, either hereditary or acquired, marked by abnormal or excessive bleeding and/or bruising. The most effective methods for assessing coagulation disorders include a detailed history and a series of blood tests. Clinical examination findings are notable but may be less specific. If a surgical patient has a bleeding disorder discovered preoperatively, postoperatively, or intraoperatively, treatments exist with medications, surgical management, interventional radiology procedures, and replacement therapy.

Cancers are chronic manageable diseases in the era of the second phase of the Cancer Moonshot program by the US government. Patients with cancer suffer from various forms of orthopaedic morbidities, namely locomotive syndrome in cancer patients (Cancer Locomo). Type I encompasses orthopaedic conditions directly caused by cancers such as pathological fractures. Type II includes conditions caused by cancer treatments in cases of osteopenia, bone necrosis, insufficiency fractures, nonunions, and postsurgical complications. Type III defines coexisting conditions such as arthritis. The fundamental philosophy is that orthopaedic surgeons facilitate lifesaving ambulatory anticancer drug therapies by preventing and improving Cancer Locomo. Skeletal metastasis-specific procedures are evolving currently. Recently emerging percutaneous ambulatory minimally invasive procedures address skeletal reinforcement and local cancer control while avoiding many complications and drawbacks from extensive open surgical reconstructive procedures. Three-dimensional imaging techniques are useful but are not always available for acetabular procedures in all healthcare facilities. In this review, the techniques of percutaneous guidewire and antegrade cannulated screw placement under standard C-arm fluoroscopy are described in detail. In addition, cancer-induced bone loss, biomechanical data of percutaneous skeletal reinforcement, and clinical outcomes of minimally invasive procedures were reviewed.

Introduction: Previous research has highlighted conflicts of interest stemming from industry funding and education of orthopaedic surgeons. This study sought to define the nature and magnitude of industry payments to orthopaedic surgery fellowship program directors (FPDs) in the United States.

Methods: This was a retrospective cohort study of orthopaedic surgery FPDs during 2021. Data were obtained from the Accreditation Council for Graduate Medical Education (ACGME) and Centers for Medicare and Medicaid Services. Profiles of orthopaedic surgery FPDs were obtained for ACGME-accredited and non-ACGME-accredited training programs. Nonresearch industry payments from 2015 to 2021 were extracted and adjusted for inflation. Temporal trends were analyzed through the calculation of compound annual growth rates. Comparisons were made with nonparametric tests.

Results: Of 600 orthopaedic surgery FPDs, 596 received industry funding (99%), which totaled $340.6 million over the study period. A trend toward greater total annual industry payments over the study period was observed (compound annual growth rate = 3.3%, P = 0.009). Most industry payments were for royalties or licensing ($246.6 million, 72.4%) and consulting fees ($53.6 million, 15.7%). The median total payment per orthopaedic surgery FPD was $49,971 (interquartile range [IQR], $291,674), with 22% receiving between $100,000 and $500,000 and 17% receiving more than $500,000. The highest annual industry payments existed in shoulder and elbow ($41,489, IQR, $170,613) and spine surgery ($26,103; IQR, $84,968). ACGME accreditation status did not influence the magnitude of industry compensation to orthopaedic surgery FPDs across subspecialties (P > 0.05). Men had higher total median annual industry payments versus women ($7,799 [IQR, $47,712] versus $1,298 [IQR, $6,169], P < 0.001).

Discussion: Industry payments to orthopaedic surgery FPDs are ubiquitous, but the magnitude varies by subspecialty. Most industry funding was found in shoulder and elbow and spine surgery. Standards for orthopaedic fellowship education, such as those upheld by accrediting bodies, should include guidelines on how FPDs handle and disclose financial relationships with industry.

Introduction: Nontobacco nicotine products, including e-cigarettes and vaping, are marketed as healthier alternatives to tobacco. However, the literature on nontobacco nicotine dependence (NTND) is scarce. It is important to analyze the influence of these products as they pertain to medical and surgical postoperative complications. This study hypothesizes that patients with NTND will experience more postoperative complications.

Methods: Using the TriNetX database, which aggregates deidentified medical records from 89 healthcare organizations in the Research Network, Current Procedural Terminology and 10th revision of the International Classification of Diseases codes were used to identify patients undergoing primary shoulder arthroplasty (SA) from January 2012 to February 2024. Patients were divided into cohorts based on their NTND status before surgery. 90-day major medical complications and 2-year implant-related complications were assessed. Statistical analyses involved calculating risk ratios for postoperative complications.

Results: This study analyzed a total of 89,910 SA patients, of which 6,756 were 1:1 propensity matched into NTND or control cohorts. Within the 90-day postoperative period, the NTND cohort exhibited significantly higher rates of sepsis (1.80 vs. 1.20, P = 0.012), surgical site infection (1.20 vs. 0.70%, P = 0.007), and wound disruptions (0.70 vs. 0.40%, P = 0.048), average opioids prescribed (4.46 vs. 3.338, P < 0.001), readmission (10.20% vs. 6.20%, P 0.001) compared with the non-NTND cohort. At the 2-year follow-up, mechanical loosening was notably higher in the NTND group (1.10 vs. 0.30%, P 0.001), as were rates of prosthetic joint infections (2.20 vs. 1.20%, P 0.001). No significant difference was observed for revision rates (3.20% vs. 2.90%, P = 0.269).

Discussion: NTND is associated with higher 90-day rates of wound distruptions, infections, sepsis, as well as increased rates of mechanical loosening and prosthetic joint infection at 2 years postoperatively after SA. These results highlight the need for comprehensive NTND preoperative screening and tailored patient counseling in this patient population.

Introduction: To assess whether a diagnosis of preexisting anemia impacts outcomes of geriatric hip fractures.

Methods: This is a retrospective comparative study conducted at a single, urban hospital system consisting of an orthopaedic specialty hospital, two level 1 trauma centers, and one university-based tertiary care hospital. Data of patients aged 55 years or older with a femoral neck, intertrochanteric, or subtrochanteric hip fracture (AO/OA 31A, 31B, and 32A-C) at a single hospital center treated from October 2014 to October 2023 were retrieved from an institutional review board-approved database. Patients were included if they had a hemoglobin measurement recorded between 6 and 12 months before hospitalization for their hip fracture. Patients were cohorted based on whether their hemoglobin values recorded anemic or not. Comparative analysis was conducted to analyze 1-year mortality, 30-day mortality, 30-day readmission, 90-day readmission, and inpatient major complications.

Results: Four hundred ninety-eight patients had hemoglobin values recorded at 6 to 12 months before their surgery in the electronic medical record. Two hundred seventy-three patients (54.8%) were considered anemic at that time, whereas 225 patients (45.2%) were not. Cohorts were markedly different regarding sex, Charlson Comorbidity Index, preinjury ambulatory status, and Score for Trauma Triage in Geriatric and Middle-Aged Patients (STTGMA) score (P < 0.05 for all). Multivariable analysis revealed that chronic preinjury anemia patients had a higher likelihood of 1-year mortality and a higher risk of major inpatient complication and 30- and 90-day readmission (P < 0.05 for all).

Conclusion: Chronic preinjury anemia within 6 to 12 months before a hip fracture is associated with an increased risk of 1-year mortality, inpatient major complications, and 30- and 90-day readmission after hip fracture fixation.

Level of evidence: Level III.

The original review article, published in 2006, describing leg length discrepancy after total hip arthroplasty commented that "equal leg length should not be guaranteed." There has been considerable advancement in surgical technique and technology over the past decade, allowing surgeons to "hit the target" much more consistently. In this interval paper, we review leg length discrepancy and introduce some technologies designed to mitigate this complication. In addition, we present challenging clinical scenarios in which perceived leg length may differ from true leg length and how these can be addressed with proper workup and surgical execution.
