Education, Language, and Cultural Concordance Influence Patient-Physician Communication in Orthopaedics.

BACKGROUND: Orthopaedic surgery has a diversity gap, as it is not representative of the racial or sex proportions of the U.S. population. This gap can lead to communication barriers stemming from health literacy, language proficiency, or cultural discordance that may contribute to current health inequities. This study assesses the influence of educational attainment, language, and cultural concordance on patient-physician communication. METHODS: In this cross-sectional study, 394 patients from an urban orthopaedic clinic were administered a Likert-type survey regarding race or ethnicity, educational level, communication, patient satisfaction, language proficiency, and culture. One-way analysis of variance, chi-square tests, and Welch t tests were used to evaluate responses. RESULTS: The majority of subjects identified as African-American/Black (50%) or Hispanic/Latino (30%). Completing high school was associated with a better ability of the subjects to communicate with their orthopaedic surgeon (p < 0.001). Hispanic subjects reported lower English proficiency (p < 0.001) and decreased ability to communicate with their physician (p < 0.001) compared with other subjects, with educational attainment influencing their ability to understand their orthopaedic surgeon in English (p < 0.001). African-American and Hispanic patients placed greater importance on orthopaedic surgeons understanding their culture than White patients (p < 0.001). Hispanic patients who saw a language and culture-concordant surgeon valued having a Spanish-speaking surgeon more than Hispanic patients who did not see a concordant surgeon (p = 0.04). CONCLUSIONS: These results suggest that patient-physician language concordance, particularly in patients with lower education, may be essential to delivering high-quality patient care. Hispanic and African-American patients placed significantly greater importance on their orthopaedic surgeons understanding their culture. Hispanic patients frequently sought care with language-concordant surgeons and placed higher value on physicians understanding their culture. To better serve minority communities, efforts should be made to increase orthopaedic surgeons' cultural humility and to recruit a diverse multilingual surgeon workforce. CLINICAL RELEVANCE: This research demonstrates that cultural and language concordance, specifically between Hispanic patients and Hispanic, Spanish-speaking surgeons, can significantly enhance patient preference and potentially improve patient satisfaction and outcomes in orthopaedic care. Additionally, it underscores the importance of understanding and addressing the diversity within the field and the patient population to better meet the needs of a multicultural society.

Hand size affects branching of the deep ulnar nerve and deep palmar arch.

PURPOSE: Understanding the anatomy of the deep neurovascular structures of the hand is essential in surgical planning. There is a lack of literature regarding hand size and its influence in branching variation and the distances between branches of various neurovascular structures. Our study quantifies the variation in branching distances of the deep ulnar nerve and deep palmar arch branches. METHODS: Twenty-five fresh-frozen cadaveric hands were dissected. Each branch of the deep ulnar nerve and deep palmar arch was identified. The distance from the most distal portion of the pisiform to the proximal aspect of the branch was measured. The relationship between the length of the third metacarpal and the distance of each branch from the pisiform was examined. RESULTS: There was no relationship between branching differences in the deep ulnar nerve and the length of the third metacarpal. There was a significant association between the length of the third metacarpal and the second, third, and fourth branches of the deep palmar arch (p < 0.05). CONCLUSIONS: Our study found a significant association between the branching distances of the second, third, and fourth branches of the deep palmar arch and hand size as measured by the length of the third metacarpal.

The Optimized Oxford Hip Skeletal Maturity System Proves Resilient to Rotational Variation.

BACKGROUND: The recently described optimized Oxford skeletal maturity system utilizes anteroposterior (AP) hip radiographs to accurately, rapidly, and reliably estimate skeletal maturity. However, in the real-world setting, significant positional variation in AP hip radiographs may influence the accuracy of optimized Oxford skeletal age estimates. We sought to evaluate the consistency of skeletal age estimations using the optimized Oxford system between differently rotated radiographs. METHODS: Thirty normal computerized tomography scans of males (15 children, 9 to 15 y) and females (15 children, 8 to 14 y) were obtained retrospectively, converted into 3D reconstructions, and then used to produce simulated hip radiographs in five different rotational positions. The optimized Oxford system was applied to the 150 simulated AP hip radiographs (5 differently rotated views of 30 hips) to produce a skeletal age estimate for each. RESULTS: Rotational position did not have a statistically significant effect on the skeletal age (P=0.84) using 1-way repeated measures analysis of variance. Of the 5 radiographic parameters in the optimized Oxford system, only greater trochanter height showed significant rotational variation after Greenhouse-Geisser correction (F2.58, 74.68=5.98, P<0.001). However, post hoc analyses showed that the greater trochanter height obtained at the most centered position was not different from the other 4 rotational positions (P>0.05 for all). CONCLUSION: The optimized Oxford skeletal maturity system is resilient to rotational variation. Mildly to moderately rotated radiographs obtained in the modern clinical setting can be used for skeletal age estimation by this method, broadening the clinical usage of this system. LEVEL OF EVIDENCE: Level III-diagnostic study.

Skeletal Maturity Using Knee X-rays: Understanding the Resilience of 7 Radiographic Parameters to Rotational Position.

BACKGROUND: Recently, a skeletal maturity system using knee radiographs, named the modified Roche-Wainer-Thissen (RWT) system, has been developed using 7 discrete radiographic parameters. While the system has been shown to significantly outperform the Greulich and Pyle atlas, the effect of rotational variation of the knee radiograph on skeletal maturity determinations has not been studied. METHODS: Normal knee computed tomography scans of 12 male children ages 10 to 16 years and 8 female children ages 8 to 14 years were obtained retrospectively, converted into 3-dimensional reconstructions, and then used to simulate knee radiographs in 5 different rotational positions. Images were graded using the modified RWT system, and 1-way repeated measures analysis of variance was used to compare skeletal age in the patella centered view versus the other positions. We next retrospectively found 85 pediatric patients with both bilateral standing anteroposterior hip to ankles and separate knee radiograph within 6 months of each other. The skeletal maturity values from the 2 different radiographs were compared in 39 males between the ages of 10 and 16 years and 46 females between 8 and 14 years of age using paired t test and Wilcoxon-signed rank test. RESULTS: On the computed tomography scan-based images, there was no statistically significant effect of rotational position on the modified RWT score using repeat measures analysis of variance (P=0.210). Only the width ratio of the tibial epiphysis and metaphysis and the width ratio of the fibular epiphysis and metaphysis were statistically different between rotational positions (P<0.05). Comparing clinical full length versus knee radiographs, we found a small difference of 0.069 years which trended towards a statistically significant difference (P=0.009). CONCLUSIONS: This retrospective study supports the resilience of the RWT model to rotational variation, reassuring clinicians that bone age estimation can be performed in a slightly rotated knee x-ray within a reasonable margin of error. These results can minimize the number of radiographs needed to assess skeletal maturity limiting radiation exposure and expedite clinical flow. LEVEL OF EVIDENCE: Level-III-diagnostic study.

Patient-Reported Complications after Intravitreal Injection and Their Predictive Factors.

PURPOSE: The intravitreal injection (IVI) of pharmacologic agents is the most commonly performed ocular procedure and is associated with a host of complications. Most IVI-related complications data are derived from randomized controlled clinical trials, which report a high adverse event rate. The nature of these protocol-driven trials limit their applicability to the diverse circumstances seen in routine clinical practice. The goal of this study was to determine the prevalence of patient-reported IVI-related complications, their risk factors, and the manner in which patients sought treatment at a tertiary eye care center. DESIGN: Retrospective, institutional review board-approved study. PARTICIPANTS: Forty-four thousand seven hundred thirty-four injections in 5318 unique patients at the Cleveland Clinic Cole Eye Institute from 2012 through 2016. METHODS: Intravitreal injection. MAIN OUTCOME MEASURES: Complication occurrence within 15 days of injection. RESULTS: From 2012 through 2016, a total of 44734 injections were performed in 5318 unique patients. Overall, complication rates were low, representing 1.9% of all injections, with 1031 unique complications in 685 patients (12.9%). The most common minor complications, or those not requiring intervention, were irritation (n = 312) and subconjunctival hemorrhage (n = 284). The most common serious complications, or those requiring intervention, were corneal abrasion (n = 46) and iritis (n = 31). Most complications (66%) were managed adequately by a telephone or Epic (Epic Systems Corp., Verona, WI) electronic message encounter only. Importantly, no injection protocol parameter, such as type of anesthesia, preparation, or post-injection medication, increased the risk of a complication. However, a patient's gender, age, number of previous injections, and provider strongly influenced the risk of patient-reported complications. CONCLUSIONS: Overall, complication rates seen in routine clinical practice were low compared with clinical trial reporting. Providers should feel confident in the safety and administration of IVI during times when follow-up office visits and resources may be limited. When performing an IVI, factors such as a patient's gender, age, number of previous injections, and provider must be taken into account to ensure the best possible outcomes.
