Case Reports
Cervical epidural steroid injection with intrinsic spinal cord damage. Two case reports.
Intrinsic cervical spinal cord damage represents the serious and permanent complications that can occur if cervical epidural steroid injections are administered while the patient is sedated. Two case reports are presented. ⋯ These case reports indicate fluoroscopic guidance will not insure or prevent intrathecal perforation or spinal cord penetration during the administration of cervical epidural steroid injections. In addition, although intravenous sedations during cervical epidural steroid injections have been used numerous times without reported complications, it appears intravenous sedation in these two cases resulted in the inability of the patient to experience the expected pain and paresthesias at the time of spinal cord irritation. Therefore, the authors conclude that the patient should be fully awake during the administration of cervical epidural steroid injections, with only local anesthetic in the skin used for analgesia.

Retrospective analysis of a spine imaging center's records of patients with chronic low back pain referred by tertiary care facilities. ⋯ The interobserver reliability of detecting a high-intensity zone and the positive predictive value of the presence of a high-intensity zone for detecting a severely disrupted and exactly painful disc were much lower than previous studies have shown. The relatively low positive predictive value may be attributable to differences in sample characteristics or procedural variations, or suggest that a high-intensity zone is not indicative of exactly painful internal intervertebral disc disruption.

This case report illustrates the need to be aware of extraspinal causes of sciatica. A patient with a strangulated sciatic hernia showed the clinical features of sciatic leg pain, intestinal obstruction, and a left gluteal abscess. ⋯ The possibility of local pathology causing sciatic nerve compression should be considered when a patient reports sciatic leg pain, particularly if the presentation is atypical. Intestinal obstruction or the presence of a gluteal mass should suggest the possibility of a sciatic hernia.

An international group of back pain researchers considered recommendations for standardized measures in clinical outcomes research in patients with back pain. ⋯ Standardized measurement of outcomes would facilitate scientific advances in clinical care. A short, 6-item questionnaire and a somewhat expanded, more precise battery of questionnaires can be recommended. Although many considerations support such recommendations, more data on responsiveness and the minimally important change in scores are needed for most of the instruments.

A retrospective review of a clinical series. ⋯ Isolated stable burst fracture of the atlas can be treated effectively with a rigid cervical collar alone for 10 to 12 weeks with good neurologic recovery and segmental stability. Unstable Jefferson fractures with concurrent unstable fracture of other cervical vertebrae, especially C2, requires surgical stabilization.
