Infectious complications after epidural anesthesia are infrequent and the most common are epidural and subdural abscess. We report one rare case of vertebral osteomyelitus associated with an epidural catheter and review the literature.

(1) To determine the prevalence of cervical zygapophyseal joint pain in a specialist clinical setting; (2) to review the number of diagnostic blocks needed to identify the segmental level of the symptomatic joints; and (3) to determine the distribution of segmental levels of cervical zygapophyseal joint pain in a clinical setting. ⋯ The prevalence of cervical zygapophyseal joint pain estimated in this clinical study is lower than that found in previous research setting studies, but our requirement for confirmation by a repeat block (which many patients declined) makes our estimate conservative; it is likely that the true prevalence is higher. Zygapophyseal joints are clearly a common source of pain in patients presenting with chronic neck pain, with or without headache. Cervical zygapophyseal joint pain is readily diagnosable, enabling patients to seek further, targeted treatment.

Therapeutic efficacy of selective nerve root blocks in the treatment of lumbar radicular leg pain.
The objective of this study was to investigate the clinical effectiveness of nerve root blocks (i.e., periradicular injection of bupivacaine and triamcinolone) for lumbar monoradiculopathy in patients with a mild neurological deficit. We have retrospectively analysed 30 patients (29-82 years) with a minor sensory/motor deficit and an unequivocal MRI finding (20 disc herniations, 10 foraminal stenoses) treated with a selective nerve root block. ⋯ Twenty-six patients (87%) had rapid (1-4 days) and substantial regression of pain, five required a repeat injection. 60% of the patients with disc herniation or foraminal stenosis had permanent resolution of pain, so that an operation was avoided over an average of 16 months (6-23 months) follow-up. Nerve root blocks are very effective in the non-operative treatment of minor monoradiculopathy and should be recommended as the initial treatment of choice for this condition.
