Objective: Spinal cord stimulation (SCS) is an established treatment for chronic pain. However, dominant back pain still remains a challenge for traditional spinal cord stimulation. This case series presents our first experience with a minimally invasive percutaneously implantable, 32 contacts, current steering hence high precision spinal cord stimulation system.
Method: Data was collected prospectively. Patients were implanted percutaneously with two leads, 16 contacts each (Boston Scientific Infinion). Implantation was performed under local anaesthesia. Excessive patient interactive paraesthesia testing enabled the implanter to place the lead with high precision. Leads were generally placed between segments T6-T9 and in midline position. Patients underwent one week trial stimulation. Upon successful trial an implantable pulse generator (Boston Scientific, Precision Plus) was implanted.
Results: 6 FBSS patients with dominant back and leg pain underwent a trial phase with 32 contacts, high precision spinal cord stimulation. All patients had a successful trial (mean duration 7 days). After 6 months the mean back pain decreased from VAS 8.5±0.5 to 2±1. No complications were observed.
Conclusions: Our data shows high precision spinal cord stimulation to be safe and effective. The approach offers a novel elegant, patient interactive procedure for dominant back pain patients.
