Alternative Implantation Site of Intrathecal Pump in the Submuscular Plane of the Pectoralis Major Muscle: A Case Report

An intrathecal drug delivery system (IDDS) has been widely utilized in the management of chronic pain and spasticity when oral pharmacologic agents are deemed ineffective. Typically, intrathecal pumps are implanted in the abdominal region; however, previous case reports have described nontraditional pump implantation sites, such as anterior thigh, gluteal region, and iliac fossa. Adding to the growing literature of alternative implantation sites, this case report discusses the implantation of the pump into the submuscular plane of the pectoralis major muscle and reviews the advantages and disadvantages of this location.
