ReviewThe use of lumbar epidural/transforaminal steroids for managing spinal disease.
Lumbar epidural steroid injections are used to manage low back and leg pain (ie, sciatica). Utilization of the procedure is increasing, with Medicare spending for lumbar epidural procedures topping $175 million annually. Few prospective randomized controlled trials have clearly demonstrated the efficacy of epidural steroid injections; many have shown conflicting results. ⋯ Methodologic flaws limit interpretation of results from most scientific studies. As a tool for predicting surgical outcome, epidural spinal injection has been found to have a sensitivity between 65% and 100%, a specificity between 71% and 95%, and a positive predictive value as high as 95% for 1-year surgical outcome. Despite inconclusive evidence, when weighing the surgical alternatives and associated risk, cost, and outcomes, lumbar epidural steroid injections are a reasonable nonsurgical option in select patients.

Clavicular fractures represent 2.6% to 5% of all fractures, and middle third fractures account for 69% to 82% of fractures of the clavicle. The junction of the outer and middle third is the thinnest part of the bone and is the only area not protected by or reinforced with muscle and ligamentous attachments. These anatomic features make it prone to fracture, particularly with a fall on the point of the shoulder, which results in an axial load to the clavicle. ⋯ However, when midshaft clavicular fractures are completely displaced or comminuted, and when they occur in elderly patients or females, the risk of nonunion, cosmetic deformity, and poor outcome may be markedly higher. Thus, some surgeons propose surgical stabilization of a complex midshaft clavicular fracture with either plate-and-screw fixation or intramedullary devices. Further randomized, prospective trials are needed to provide better data on which to base treatment decisions.

The patient with neurogenic claudication resulting from lumbar spinal stenosis who fails to experience satisfactory relief from nonsurgical measures has limited treatment options. Lumbar epidural steroid injections and surgical laminectomy are generally accepted alternatives for the patient with moderate to severe symptoms. ⋯ Sufficient medium- and long-term data are lacking, however, particularly with respect to durability of symptomatic relief and the risk of device migration or dislocation. Although interspinous process spacers are a promising new technology, the results of longer-term clinical follow-up studies are needed to more clearly define their role in the management of lumbar spinal stenosis.
