Reliability and ease of use of the Itrel 3 System (Medtronic Inc., Minneapolis, MN) were prospectively assessed over 5 years in patients with a range of pain syndromes (mainly low back and/or leg pain, or ischemic pain due to peripheral vascular disease). The longevity of the implantable pulse generator (IPG) battery, the frequency with which system settings were changed, and the ease of use of the EZ patient programmer were assessed. Data on adverse events, pain relief, and patient satisfaction with therapy were also collected. ⋯ The intensity and duration of pain were reduced significantly and patient satisfaction with therapy was high. We conclude that the Itrel 3 System performed well over 5 years and was easy to use. Its safety and effectiveness for the relief of chronic intractable pain of the trunk or limbs were also confirmed.

Comparative StudyCircumferential and posterolateral fusion for lumbar disc disease.
Clinical outcome of low back fusion is unpredictable. There are various reports discussing the merits and clinical outcome of these two procedures. The patients were selected from a population of patients who had chronic low back pain unresponsive to conservative treatment. ⋯ The posterolateral fusion group had a 63.9% satisfactory outcome and the posterior lumbar interbody fusion group had an 80% satisfactory outcome using the Oswestry disability index for postoperative assessment. There was 61.1% improvement in working ability in the posterolateral fusion group and 77.1% improvement in the posterior lumbar interbody fusion group which was not statistically significant. The authors consider instrumented circumferential fusion with posterior lumbar interbody fusion better than instrumented posterolateral fusion for managing chronic disabling low back pain.

To document the prevalence of low back pain (LBP) in Flemish adolescents and to recognize the association between perceived social support and affect and medical consultation and reduction of activities. ⋯ The results of the present study encourage further research on the role of pain perception and the influence of psychosocial factors on back pain in adolescents.

This study sought to determine the efficacy of fluoroscopic caudal epidural steroid injections as a conservative treatment in patients with presumably chronic lumbar discogenic pain. ⋯ At greater than two year follow-up, the efficacy of fluoroscopically guided caudal epidural steroid injections in patients with chronic lumbar discogenic pain is poor. Patient satisfaction exceeds the reported rate of efficacy. Patients responding to injection have significantly lower pre-injection pain scores.

It is widely believed that the extent of a patient's subjective complaints are often based on developmental, psychological, social, and cultural factors rather than structural or physical pathology. In patients presenting with chronic low back pain, underlying behavioral problems may not be immediately apparent. These behavioral or non-physiological issues may be secondary to a deliberate deception or may be associated with psychological distress. ⋯ Results showed that 27 patients (22%) presented with non-physiological symptoms, 34 patients (28%) with non-physiological signs, and 19 patients (16%) with combined presence of non-physiological signs and symptoms. Overall there was significant correlation of non-physiological signs with depression, anxiety, and somatization, both by diagnosis of depression, diagnosis of anxiety and elevated scores. However, correlation was present for non-physiological symptoms only with elevated scores of anxiety and somatization.
