Delayed Diagnosis of Shoulder Septic Arthritis and Osteomyelitis During the COVID-19 Pandemic: The Role of Point-of-Care Ultrasound.

ABSTRACT

The diagnosis and treatment of septic arthritis are complex and require collaboration among multiple medical services, especially in the emergency department (ED). This case report highlights the difficulties in diagnosing shoulder septic arthritis, which is a rare condition in adults and can present with subtle symptoms. The patient was eventually diagnosed with septic arthritis of the left shoulder. However, the diagnosis was delayed due to the impact of the COVID-19 pandemic on obtaining an outpatient MRI and a previous shoulder injury that added confusion. Delays in diagnosis and treatment can lead to a rapid destruction of the affected joint, causing significant morbidity and mortality. This case report also highlights the importance of alternative diagnostic tools, such as point-of-care ultrasound (POCUS), which is quick, inexpensive, and may lead to earlier detection of joint effusions and prompt arthrocentesis.
