Ulnar Nerve Palsy as COVID-19 Sequelae in 3 Patients

The pathophysiology and treatment of COVID-19 have been at the forefront of medical research this past year. While great strides have been made in our knowledge of the disease, there is still much that is unknown. More than one-third of patients with COVID-19 present with symptoms involving the nervous system. The reason for this is unclear, although several theories have been postulated. In this case study, we present 3 patients with severe ulnar nerve dysfunction following treatment for COVID-19 in the intensive care unit. We discuss reasons why this may have occurred, the etiology of which is likely multifactorial. We are reporting these cases to inform and alert physicians to the possibility of ulnar nerve involvement in the presentation of patients with COVID-19.
