111 patients with local chronic non-tumour pains were included in the retrospective analysis. Indication for subcutaneous field stimulation was low back pain n = 29, failed back surgery n = 37, pain in the cervical region n = 15, post herpetic neuralgia n = 12.After implantation the pain reduction was more than 50 %, from 8.2 to 4.0. electrodes dislocation in the case of 14 patients (13 %), infection in 7 (6 %) and in 6 cases (5 %) electrode rupture.

Pain intensity score before and after STS stimulation for all 111 patients (Numerical rating scale; 0= no pain, 10= unbearable pain), (median; 8 before STS, 4 after STS), percentile 25 (8 before STS, 2 after
STS), percentile 75 (9 before STS, 5 after STS) *P<0.001

Analgesic medication according to WHO 3 steps (I-III) before and 3 months after implantation; percent of patients; WHO I (non-opioids), WHO II (weak opioids), WHO III
(strong opioids)

Aim: to assess the efficacy of Subcutaneous Stimulation for chronic pain of different origin, such as
Low Back Pain Post Zoster Neuralgia Tension Headache Trigeminal Neuropathy Upper Cervical Syndrome Occipital Neuralgia Cluster Headache Migraine
Endpoints: effect on pain and QoL (VAS, SF12, Oswestry,
BDI, …) effect on medication

- Explantation of the system
• 3 x due to infection of the leads (M01FU-M03FU)
• 1 x due to infection of the leads (M03FU-M06FU)
• 1 x due to skin irritation at IPG pocket site (M03FU – M06FU)
• 2 x because of unpleasant stimulation (1 M01FU-M03FU, 1
M03FU-M06FU)
• 3 x due to loss of efficacy

ConclusionConclusion
118 Low Back Pain patients included considerably long follow-up time: 6 months
Results are promising, as
Mean pain reduction:
- 45,3% (VAS 8,3 4,6) after 6 months
Quality of Life (Oswestry): all: -11,4% 55,9 48,6 (6M)
Considerable reduction in medication: baseline - 6 months
