RESUMEN
The literature concerning resident involvement in shoulder surgery is limited. The purpose of this study was to examine whether resident involvement across all orthopedic shoulder surgeries is associated with adverse 30-day outcomes. Utilizing the American College of Surgeons National Surgical Quality Improvement Program database, patients who underwent shoulder surgery with or without a resident present were analyzed. Independent t-test and chi-square or Fischer's exact test were used appropriately. A logistic regression model was used to calculate adjusted odds ratios. This study examined 5,648 patients: 3,455 patients in the "Attending alone" group and 2,193 in the "Attending and resident in the operating room" group. Resident presence in the operating room was not associated with increased complications, except for bleeding transfusions (OR 1.71, CI 1.32-2.21, P ≤ 0.001). This study demonstrates that resident involvement in orthopedic shoulder surgery does not present an increased risk for 30-day complications when compared to surgeries performed with the attending surgeon alone.
RESUMEN
OBJECTIVE: Concerns regarding patient safety and image quality have made the use of knee-spanning external fixators in MRI a challenging clinical scenario. The purpose of our study was to poll practicing musculoskeletal radiologists on their personal experiences regarding the use of knee-spanning external fixators in MRI in an effort to consolidate practice trends for the radiologists' benefit. METHODS: A 27-item survey was created to address the institutional use, safety, adverse events, quality, and perspectives of the radiologist related to MRI of an externally fixated knee. The survey was distributed to 1739 members of the Society of Skeletal Radiology. RESULTS: A total of 72 members of the Society of Skeletal Radiology completed the survey. Most notably, 40 of 72 (55.56%) respondents are permitted to place a knee-spanning external fixator inside the MR bore at their institution, while19 of 72 (26.39%) respondents are not permitted to do so. Fourteen of 32 (43.75%) respondents have institutional guidelines for safely performing an MRI of an externally fixated knee. Twenty-five of 32 (78.13%) respondents are comfortable permitting an MRI of an externally fixated knee. CONCLUSION: We found a general lack of consensus regarding the decision to scan a patient with a knee-spanning external fixator in MRI. Many institutions lack safety guidelines, and providers rely upon a heterogeneous breadth of resources for safety information. A re-examination of the FDA device labeling nomenclature and expectations of the individual manufacturers may be needed to bridge this gap and help direct management decisions placed upon the provider.

After emergent assessment of potentially limb-threatening injuries in knee dislocation or multi-ligament knee injury patients, magnetic resonance imaging is necessary to visualize ligamentous structures and plan for soft tissue repair. However, the application of a knee-spanning external fixator may introduce artifact and reduce overall image quality, which can limit the evaluation of soft tissue injury. As a result, the utility of MRI in the context of a knee-spanning external fixator has been called into question. Signal-to-noise ratio, contrast-to-noise ratio, and qualitative scales have been used to assess image quality of MRI in the context of a knee-spanning external fixator. Despite the potential for artifact, studies have demonstrated that useful diagnostic information may be obtained from MRI in the presence of an external fixator. This review examines the general principles of anatomical assessment, magnetic field strength, device composition and design, radiofrequency coil use, and MRI sequences and artifact reduction as they pertain to MRI in the presence of a knee-spanning external fixator.

Purpose: To examine the 30-day postoperative outcomes of resident involvement in shoulder-stabilization surgical procedures using the American College of Surgeons National Surgical Quality Improvement database. Methods: We conducted a retrospective review of the National Surgical Quality Improvement database for all shoulder-stabilization procedures from 2010 to 2018. Procedures included arthroscopic Bankart, arthroscopic Bankart with SLAP repair, arthroscopic Bankart with Remplissage, open Bankart, anterior bone block, posterior bone block, Latarjet coracoid process transfer, and capsular shift/capsulorrhaphy for multidirectional instability. Data included preoperative demographics, comorbidities, and 30-day postoperative outcomes. Cases were categorized into 2 groups: "attending alone" and "attending and resident." Statistical analysis comparing groups on demographics and comorbidities included independent t-test for continuous variables and Pearson χ2 or Fischer exact for categorical variables. A logistic regression model including propensity score was used to calculate adjusted odds ratio for outcomes. Results: A total of 3,954 patients undergoing shoulder-stabilization procedures were included in the study and 28.8% of patients had a resident involved in their procedure. Residents were more likely to be involved in procedure for patients who were of minority ethnicity (P < .001), a lower body mass index (P < .001) and less likely to have a history of chronic obstructive pulmonary disease (P = .029). Resident involvement resulted in statistically significant longer total operation time (91 vs 85 minutes, P < .001). In terms of postsurgical outcomes, complication rates were low for both groups (â¼0.8%). Resident involvement was not associated with any significant increase in 30-day postsurgical complications. Conclusions: Our results show that resident involvement in shoulder-stabilization surgery is associated with a significant increase in operative time without any significant increase in 30-day postsurgical complications. Level of Evidence: Level III, retrospective comparative study.
RESUMEN
¼ Universal safety guidelines for the use of a knee-spanning external fixator in magnetic resonance imaging (MRI) are unlikely to be established considering the high variability in device construct configurations.¼ Per the US Food and Drug Administration, manufacturers are to provide parameters for safe MRI scanning for "MR Conditional" devices; however, such labeling may be limited in detail. Physicians should reference manufacturer labels as a starting point while making an educated clinical decision.¼ Scanning of a knee-spanning external fixator inside the MR bore has been safely demonstrated in previous studies, although with small sample sizes.¼ When considering MRI in a patient treated with a knee-spanning external fixator, physicians should use all available resources and coordinate with their medical team to make a clinically reasonable decision contrasting patient benefit vs. potential harm.
