Intrathecal baclofen (ITB) administration is a common method in managing spasticity. The location of the reservoir fill port (RFP) is identified manually in most cases. However, it can be difficult due to a variety of factors, such as the formation of excess subcutaneous cellular tissue and scar formation overlying the RFP and rotation or inversion of the pump. Consequently, multiple failed attempts accessing the reservoir increases pain and risk of fatal complications (e.g., infection and withdrawal syndrome from pocket filling). We describe a successful ultrasound-guided pump refilling case after multiple failed attempts by the conventional method. This groundbreaking instrument assists this minimally invasive procedure while limiting iatrogenic injury in the treatment of spasticity. The presentation of this case shows the utility of ultrasound as an important tool to guide the procedure and prevent adverse events in a spasticity management consult.
