Evaluation and Treatment of Entrapped Peripheral Nerve Catheters: A Case Report and Review.

Methods to remove retained peripheral nerve catheters range from non-invasive techniques to open surgical procedures. This study reviews two cases requiring surgical intervention for catheter remnant removal after catheter breakage and presents a systematic review describing the diagnosis and treatment of retained perineural catheters. While still very rare, our case report and systematic review demonstrate that retained nerve catheters can occur as the result of kinking or knotting, but also from catheter breakage. We recommend risk mitigation strategies for providers placing or caring for patients with regional nerve catheters.

Learner Preferences and Perceptions of Virtual Hand Surgery Education During the COVID-19 Pandemic.

PURPOSE: In response to the COVID-19 pandemic, many postgraduate medical education lectures and conferences have been moved to a virtual platform. Questions remain regarding the effectiveness of virtual education, what types of educational offerings can be transitioned to a virtual format, and what types of curricula should still take place in person. METHODS: This study surveyed trainees from the United States who participated in a single institution's hand surgery virtual flipped classroom curriculum of 6 week-long modules. Demographics, premodule and postmodule achieved levels of learning based on Bloom's taxonomy, technology usage, and preferences were surveyed. RESULTS: Of the 65 participants, 41 (63.1%) responded to the survey. Trainees included hand surgery fellows (27/41 [65.9%]), orthopedic surgery residents (11/41[26.8%]), and plastic surgery residents (3/41 [7.3%]). On average, most trainees read, viewed, and participated in more than half of the articles (28/41 [68.3%]), electronic videos (31/41 [75.6%]), and conferences (35/41 [85.4%]) per week. The median level of achieved learning increased from "I can apply" to "I can analyze" for all modules. Self-directed learning was preferred for basic facts and knowledge (26/41 [63.4%]) and faculty-directed learning was preferred to review and practice advanced concepts (34/41 [82.9%]). The participants perceived benefits of the virtual curriculum to include increased scheduling flexibility (8/41[19.5%]), expert opinions (7/41 [17.1%]), and diversity of educational formats (3/41 [7.3%]). The perceived drawbacks included decreased interaction (8/41 [19.5%]), technical difficulties (6/41 [14.6%]), excessive detail (3/41 [7.3%]), and single-institution bias (2/41 [4.9%]). CONCLUSIONS: The flipped virtual classroom model is an effective and preferred method of instruction for trainees. Trainees achieved a higher level of learning following the completion of each week-long module. Considerations for the implementation of a virtual curriculum include content quality, quantity, and reducing single-institution bias. CLINICAL RELEVANCE: The implementation of virtual learning can enhance hand surgery education for the modern learner.
