Summary
This study details 509 plate electrode implantations for pain and motor disorders. Most electrodes remain functional, with low complication rates, highlighting surgical safety and efficacy.
Area of Science:
- Neurosurgery
- Neuromodulation
- Spinal Surgery
Background:
- Plate electrodes are utilized for managing chronic pain and motor disorders.
- Experience with a large cohort of patients undergoing electrode implantation is valuable for understanding outcomes.
Purpose of the Study:
- To summarize the surgical experience with 509 plate electrode implantations.
- To report on the efficacy and complications associated with dorsal epidural plate electrode placement.
Main Methods:
- A single neurosurgeon performed 509 plate electrode implantations in 350 patients.
- Electrodes were implanted in the dorsal epidural space for pain and/or motor disorders.
- Data on electrode types, placement levels, and complications were collected.
Main Results:
- 378 electrodes were for pain management, 106 for motor disorders, and 25 for both.
- Complications included infection (3.7%), migration (1.1%), and breakage (4 patients).
- 70% of implanted electrodes remained in use, indicating sustained therapeutic benefit.
Conclusions:
- Dorsal epidural plate electrode implantation is a viable option for chronic pain and motor disorders.
- The procedure demonstrates a favorable safety profile with manageable complication rates.
- Technical considerations for surgical implantation at various spinal levels are crucial for successful outcomes.
