We present a case of a superficial acral fibromyxoma (SAFM) of the distal aspect of the thumb with radiographic evidence of extrinsic pressure erosion of the underlying cortex. This 47-year-old woman presented with a slow-growing mass over the distal aspect of the right thumb that proved to be SAFM on surgical pathology. This is a relatively rare mesenchymal neoplasm of the periungual and subungual regions of fingers and toes.

We present a case of pelvic osteosarcoma in an 18-year-old woman with a tumor thrombus in the left iliac vein, extending to the inferior vena cava. Tumor thrombus has been rarely described with osteosarcoma, with only 14 cases in the literature.

As the pediatric population continues to increase its participation in organized athletics, there has been a corresponding increase in associated injuries. The lower extremity is the most frequently involved site in individuals age 5-18, representing about 60 % of all injuries. Children and adolescents are susceptible to injuries that differ from adults. The pelvis, knee, and ankle all present unique diagnostic challenges to the physician. MR can be helpful in the young athlete, as it can better demonstrate apophyseal, physeal, or soft tissue injury that might otherwise be unapparent or underestimated.

We present a case of failure of acromioclavicular joint (ACJ) reduction that was performed with low-profile, double-metallic button technique (Tightrope; Arthrex Inc). The patient presented with coracoid fracture and loss of reduction within eight weeks of surgery.

On March 11, 2020, the World Health Organization (WHO) declared the novel coronavirus disease (COVID-19) a pandemic. Hospitals throughout the USA and the residency programs housed therein have drastically altered their standard operations to slow the spread of disease. Maintaining the educational mission of a residency program within the parameters of social distancing mandates is an unprecedented challenge to graduate medical education and will remain so for the near future. We evaluated resident perception of our efforts to transition educational activities within the residency to an online, remote format utilizing Microsoft SharePoint. Educational conferences were transitioned to a videoconferencing platform on March 13, 2020 in conjunction with the deployment of an intradepartmental Microsoft SharePoint site to provide educational resources, disseminate scheduling changes, and provide wellness resources in response to the COVID-19 pandemic. An 11-question survey available from 4 Jan 2020–4 Jun 2020 surveyed resident perceptions of the instituted changes. Twenty-six of 31 residents (83.8%) responded to the resident survey invitation. Twenty-four of 26 residents (92.3%) characterized the SharePoint as useful. Twenty of 26 residents (76.9%) desired attending guidance as to how to utilize the online resources for each resident rotation. A total of 92.3% (24/26) of residents felt that the program’s response utilizing SharePoint engendered a greater sense of belonging to their work community. Resident perception of the transition to online learning utilizing Microsoft SharePoint as a distribution platform was generally positive, helping to mitigate untoward educational consequences of the COVID-19 pandemic.
