ABSTRACT

Nerve compression syndromes of the upper extremity are among the most common pathologies encountered in orthopaedic surgery. Symptoms can be debilitating for patients-affecting their work, activity level, sleep patterns, and overall quality of life. The community orthopaedic specialist should be familiar with the anatomy, etiology, and presentation of upper extremity nerve entrapment. Furthermore, knowledge of current evidence surrounding the management of these common syndromes can prove valuable for treating clinicians. Treatment ranges from nonsurgical (including medication and splinting) to surgical (when symptoms are severe). Although the gold standard treatment for nerve compression syndromes of the upper extremity is typically surgical release, nonsurgical methods should also be reviewed and understood because these can play an important role for patients as well. Community orthopaedic specialists should be well aware of the risks and complications associated with surgical releases.

ABSTRACT

Nail disorders are often difficult to recognize and diagnose because of the subtlety of their presentation and their shared overlapping features that are common to several conditions. Experientially, this is further complicated by the fact that specific training on diagnosis of nail pathologies varies substantially across most residency programs and for a majority of medical and surgical specialties. To distinguish these presentations from true, potentially deleterious nail disorders, clinicians should have familiarity with the most commonly occurring nail pathologies and their associations, and use a systematic approach when examining or evaluating alterations in the nails. In the present study, we review the most common clinical disorders affecting the nail apparatus.

ABSTRACT

UNLABELLED: PHENOMENON: Vocational identity may play an important role in physicians' healthy professional development. Allopathic medical students' vocational identity may bear a relationship to the level of emphasis placed on research versus service at their medical school. APPROACH: Social mission score (SMS) and the US News and World Report (USNWR) research ranking (year 2011) were used as schools' national rankings for service and research, respectively. A questionnaire was sent to 960 3rd-year medical students from 24 allopathic medical schools between January and April 2011. The scale for vocational identity was created using the responses from the Vocational Identity Scale (9 items), and we used an established cutoff from a previous study to categorize those students who had "strong" vocational identity. FINDINGS: After categorizing allopathic medical schools into four groups based on SMS rankings, we found that medical students who attended allopathic medical schools from the two highest SMS ranking groups were more likely to report scores reflecting strong vocational identities-odds ratio [OR] = 2.9, 95% confidence interval (CI) [1.8, 4.7] and OR = 2.5, 95% CI [1.6, 4.0], respectively. In contrast, we did not find any associations between students from allopathic medical schools with high USNWR rankings and likelihood of reporting scores reflecting strong vocational identities. Insights: Social mission scores for allopathic medical schools may potentially serve as predictors of professional and vocational identity development. Further research is needed to better understand these findings, as this is one of the first studies both to examine allopathic medical students' sense of vocational identity and to explore the use of SMS rankings as predictors of medical students' professional development.

ABSTRACT

Cartilage injuries of the hand and wrist can be debilitating in the athlete. Diagnosis is difficult given the broad spectrum of presenting symptomatology. History and physical examination is crucial to achieve the correct diagnosis, and advanced imaging can offer helpful assistance to the clinician as well. TFCC injuries and ulnar impaction syndrome are among the most common conditions in athletes with hand and wrist pain. Treatment of these injuries is initially nonoperative, but elite athletes may elect to bypass nonoperative treatment in favor of earlier return to sport. Surgical treatment varies but can include open and arthroscopic methods. The clinician should tailor treatment plans to each athlete based on level of competition, type of sport, and individual preferences and goals.

ABSTRACT

CASE: Throughout the COVID-19 pandemic, prone positioning has decreased mortality in patients with severe acute respiratory distress syndrome. We present the unique case of a patient who developed left median nerve mononeuropathy and bilateral meralgia paresthetica after prone positioning while afflicted with COVID-19. These nerve injuries have been rarely reported in the literature and never before in the same patient. CONCLUSION: Our case highlights the importance of increased care when positioning patients prone by padding bony prominences, evenly distributing pressure across known sites of peripheral nerve entrapment, and giving consideration to prone-positioning time intervals when caring for intubated patients.

ABSTRACT

BACKGROUND: Autologous chondrocyte implantation (ACI) is an increasingly popular technique for the treatment of articular cartilage defects. Because several companies have financial interests in ACI, it is important to consider possible conflicts of interest when evaluating studies reporting outcomes of ACI. PURPOSE: To determine whether there is an association between authors' financial conflicts of interest and the outcomes of ACI studies. STUDY DESIGN: Cross-sectional study. METHODS: A search of PubMed and MEDLINE databases for "autologous chondrocyte implantation" was performed. Clinical studies published after 2012 through May 15, 2019, and in English were included. Studies were determined to have financial conflicts of interest if any contributing author had relevant conflicts, either self-reported in the published study's disclosures section or reported online in the American Academy of Orthopaedic Surgeons Disclosure database or the Centers for Medicare & Medicaid Services Open Payments database. The outcomes of each study were rated as favorable, equivocal, or unfavorable based on predefined criteria and then tested for association with conflicts of interest through use of the Fisher exact test. RESULTS: A total of 79 studies met the inclusion criteria. Nearly all studies were of level 3 or 4 evidence. Conflicts of interest were established in 51.90% of studies (n = 41). Conflicts that were not self-reported by the authors were discovered in 18% of studies. The level of evidence was not associated with conflict of interest. No statistically significant difference was found in the rate of favorable outcomes between studies with conflicts (92.68%) and those with no conflicts (81.58%) (P = .126). Publications by US authors were more likely to have financial conflicts of interest (P = .003). CONCLUSION: Favorable results were reported in a majority of studies involving ACI. No statistical association was found between the frequency of favorable outcomes and the presence of financial conflicts of interest, country of authorship, or level of evidence. There was a trend toward more favorable outcomes in studies with conflicts of interest. Additionally, nearly 20% of publications had possible conflicts found online that were not self-reported. It is critical for orthopaedic surgeons to judiciously evaluate published studies and consider financial conflicts of interest before performing ACI techniques on patients.

ABSTRACT

BACKGROUND: Physician burnout raises concerns over what sustains physicians' career motivations. We assess whether physicians in end-of-life specialties had higher rates of burnout and/or calling to care for the dying. We also examined whether the patient centeredness of the clinical environment was associated with burnout. METHODS: In 2010 to 2011, we conducted a national survey of US physicians from multiple specialties. Primary outcomes were a validated single-item measure of burnout or sense of calling to end-of-life care. Primary predictors of burnout (or calling) included clinical specialty, frequency of encounters with dying patients, and patient centeredness of the clinical environments ("My clinical environment prioritizes the need of the patient over maximizing revenue"). RESULTS: Adjusted response rate among eligible respondents was 62% (1156 of 1878). Nearly a quarter of physicians (23%) experienced burnout, and rates were similar across all specialties. Half of the responding physicians (52%) agreed that they felt called to take care of patients who are dying. Burned-out physicians were more likely to report working in profit-centered clinical environments (multivariate odds ratio [OR] of 1.9; confidence interval [CI]: 1.3-2.8) or experiencing emotional exhaustion when caring for the dying (multivariate OR of 2.1; CI: 1.4-3.0). Physicians who identified their work as a calling were more likely to work in end-of-life specialties, to feel emotionally energized when caring for the dying, and to be religious. CONCLUSION: Physicians from end-of-life specialties not only did not have increased rates of burnout but they were also more likely to report a sense of calling in caring for the dying.

ABSTRACT

BACKGROUND: Replicating humeral anatomy during shoulder arthroplasty is important for good patient outcomes. The proximal humeral geometry of the Chinese population has been rarely reported. We analyzed the geometry of the proximal part of the humerus in Chinese subjects and compared it with that of Western populations and the dimensions of available prostheses. METHODS: Eighty healthy Chinese subjects underwent computed tomography (CT)-arthrography. Three-dimensional (3D) digital humeral and glenoid models were reconstructed, and geometric parameters were measured. Humeral measurements included the radius of curvature, articular surface diameter and thickness, anterior-posterior/superior-inferior (AP/SI) articular surface diameter ratio, articular surface thickness/radius of curvature ratio, surface arc, inclination angle, retroversion angle, and medial and posterior offsets. Glenoid measurements included SI length, AP length, SI radius, and AP radius. RESULTS: The average radius of curvature (and standard deviation) of the humeral head was 22.1 ± 1.9 mm, the articular surface diameter averaged 42.9 ± 3.6 mm, and the articular surface thickness averaged 16.9 ± 1.5 mm. There was strong linear correlation between the articular surface diameter and thickness (r = 0.696, p = 0.001), with a linear regression relationship of thickness = 0.357 × diameter + 1.615. The AP/SI articular surface diameter ratio averaged 0.93 ± 0.03; the articular surface thickness/radius of curvature ratio, 0.77 ± 0.05; the surface arc, 153° ± 5.6°; the inclination angle, 133° ± 3.1°; and the retroversion angle, 22.6° ± 10.2°. The medial and posterior offsets averaged 6.3 ± 0.9 mm and 0.4 ± 0.78 mm, respectively; the SI and AP lengths, 30.15 ± 3.70 mm and 20.35 ± 2.56 mm; and the SI and AP radii, 23.49 ± 2.48 mm and 25.54 ± 3.07 mm. Compared with the Western population, the Chinese cohort had a smaller radius of curvature (p < 0.001), smaller articular surface diameter (p = 0.009), larger articular surface thickness/radius of curvature ratio (p < 0.001), larger surface arc (p < 0.001), smaller inclination angle (p < 0.001), and smaller posterior offset (p < 0.001). Unlike the Western population, the Chinese population had higher glenohumeral conformity in the coronal plane than in the axial plane. Many manufacturers' shoulder prostheses do not adequately cover the range of humeral head dimensions in our Chinese cohort. CONCLUSIONS: The geometric parameters of the humeri in the Chinese population differ from those in other populations. These differences have clinical relevance with regard to implant design and arthroplasty technique and likely affect clinical outcomes.
