BackgroundWomen and minorities remain underrepresented in orthopaedic surgery. In an attempt to increase the diversity of those entering the physician workforce, Nth Dimensions implemented a targeted pipeline curriculum that includes the Orthopaedic Summer Internship Program. The program exposes medical students to the specialty of orthopaedic surgery and equips students to be competitive applicants to orthopaedic surgery residency programs. The effect of this program on women and underrepresented minority applicants to orthopaedic residencies is highlighted in this article.Questions/purposes(1) For women we asked: is completing the Orthopaedic Summer Internship Program associated with higher odds of applying to orthopaedic surgery residency? (2) For underrepresented minorities, is completing the Orthopaedic Summer Internship Program associated with higher odds of applying to orthopaedic residency?MethodsBetween 2005 and 2012, 118 students completed the Nth Dimensions/American Academy of Orthopaedic Surgeons Orthopaedic Summer Internship Program. The summer internship consisted of an 8-week clinical and research program between the first and second years of medical school and included a series of musculoskeletal lectures, hands-on, practical workshops, presentation of a completed research project, ongoing mentoring, professional development, and counselling through each participant’s subsequent years of medical school. In correlation with available national application data, residency application data were obtained for those Orthopaedic Summer Internship Program participants who applied to the match between 2011 through 2014. For these 4 cohort years, we evaluated whether this program was associated with increased odds of applying to orthopaedic surgery residency compared with national controls. For the same four cohorts, we evaluated whether underrepresented minority students who completed the program had increased odds of applying to an orthopaedic surgery residency compared with national controls.ResultsFifty Orthopaedic Summer Internship scholars applied for an orthopaedic residency position. For women, completion of the Orthopaedic Summer Internship was associated with increased odds of applying to orthopaedic surgery residency (after summer internship: nine of 17 [35%]; national controls: 800 of 78,316 [1%]; odds ratio [OR], 51.3; 95% confidence interval [CI], 21.1–122.0; p < 0.001). Similarly, for underrepresented minorities, Orthopaedic Summer Internship completion was also associated with increased odds of orthopaedic applications from 2011 to 2014 (after Orthopaedic Summer Internship: 15 of 48 [31%]; non-Orthopaedic Summer Internship applicants nationally: 782 of 25,676 [3%]; OR, 14.5 [7.3–27.5]; p < 0.001).ConclusionsCompletion of the Nth Dimensions Orthopaedic Summer Internship Program has a positive impact on increasing the odds of each student participant applying to an orthopaedic surgery residency program. This program may be a key factor in contributing to the pipeline of women and underrepresent...

The lack of sex and racial diversity of the physicians within the specialty of orthopaedic surgery was recognized decades ago, and formal steps to address these issues began in 1983 with the founding of the Ruth Jackson Orthopaedic Society and the J. Robert Gladden Orthopaedic Society. Despite the efforts of these organizations, the work of other interested groups, and the growing diversity in medical student demographics, physician diversity in orthopaedic surgery remains disproportionately poor relative to the populations that we serve as a specialty.

Women and underrepresented medical students are frequently unable to see, identify, or interact with an orthopaedic surgeon who looks like them. Simultaneously, these students are repeatedly challenged about their aspirations and questioned about their ability to become an orthopaedic surgeon. Ultimately, students from marginalized groups are unable to envision any future role as an orthopaedic surgeon and are actively diverted to other medical specialties. Nth Dimensions has developed programming that provides relatable role models, consistent positive affirmation, hands-on surgical and research experiences, and exposure to a community that expects for the scholars to succeed. In addition, Nth Dimensions has developed a series of best practices, or “steps,” designed to help orthopaedic surgery training programs successfully recruit and retain diverse residents and faculty and ensure their success by providing a safe, all-inclusive learning and working environment.

Introduction: The purpose of this systematic review is to identify whether poor nutrition, as defined by the more commonly used markers of low albumin, low transferrin, or low total lymphocyte count (TLC), leads to more postoperative complications. We hypothesized that it may be possible to identify the levels of these laboratory values at which point total joint arthroplasty (TJA) may be ill advised. To this end, we analyzed the available literature regarding links between these three variables on postoperative complications after TJA. Methods: This systematic review was done in two parts: (1) In the first part, we reviewed the most commonly used malnutrition marker, albumin. (2) In the second part, we reviewed TLC and transferrin. We accessed PubMed, EMBASE, and Cochrane Library using relevant keywords to this study. The biostatistics were visualized using a random-effects forest plot. We compared data from all articles with sufficient data on patients with complications (ie, cases) and patients without complications (ie, noncases) among the two groups, malnourished and normal nutrition, from albumin, transferrin, and TLC data. Results: A meta-analysis of seven large-scale articles detailing the complications of albumin led to an all-cause relative risk increase of 1.93 when operating with hypoalbuminemia. This means that in the studies detailed enough to incorporate in this pooled analysis, operating on elective TJAs with low albumin is associated with a 93% increase in all measured complications. In the largest studies, analysis of transferrin levels for the most common complications revealed a relative risk increase of 2.52 when operating on patients with low transferrin levels. There were not enough subjects to do a biostatistical analysis in articles using TLC as the definition of malnutrition. Conclusion: The focus is on the trends rather than absolutes. As shown in Table 1, whether the albumin cutoff for albumin was 3.0 g/dL, 3.5 g/dL, or 3.9 g/dL, the trend remains the same. Because low albumin before TJAs tends to increase complications, it is recommended to incorporate albumin levels in preoperative workups. Many patients with hip and knee arthritis undergo months of conservative management (eg, physical therapy and corticosteroid injections) before considering surgery, and it would be wise to optimize their nutritional status in this period to minimize the risk of perioperative complications. The physician should use these data to provide informed consent of the increased risk to patients planning to undergo TJAs with elevated malnutrition markers. Because this research is retrospective in nature, albumin should be studied prospectively in hypoalbuminemic and normoalbuminemic patients and their postoperative outcomes should be measured. Regarding transferrin and TLC, future research should help elucidate their predictive value and determine the value of preoperatively optimizing them and their eff...
