The clinical importance of lumbar pathology identified on magnetic resonance imaging (MRI) remains unclear. It is plausible that pathology seen on MRI is a risk factor for a recurrence of low back pain (LBP); however, to our knowledge, this has not been investigated by previous studies. ⋯ We identified promising risk factors for a recurrence of LBP, which should be further investigated in larger trials. The findings suggest that pathology seen on MRI plays a potentially important role in recurrence of LBP.

Posterior vertebral column resection (PVCR) is a challenging but effective technique for the correction of complex spinal deformity. However, it has a high complication rate and carries a substantial risk for neurologic injury. ⋯ Posterior vertebral column resection for severe spine deformity is technically demanding and carries a substantial risk. The apex is a variable that influences the occurrence of neurologic complications, and the presence of a TH apex in particular could be a preoperative risk factor for neurologic complications.

Case Reports
Multifocal hemangioendothelioma of the lumbar spine and response to surgical resection and radiation.
Epithelioid hemangioendothelioma rarely occurs in the lumbosacral spine, with very few case reports of spinal hemangioendothelioma in the literature. There is variability in aggressiveness of these lesions without established treatment guidelines. ⋯ Spinal hemangioendothelioma is a rare disease and can present in variable forms, including as a multifocal regional process--which may be mistaken for infection. Additionally, there are no standard treatment protocols for this entity. We present the extensive imaging and treatment of a single case of rapidly progressive lumbar epithelioid hemangioendothelioma, which to our knowledge has not been described with this multifocal appearance in the lumbar spine.

Epidural corticosteroid injections are commonly used to treat back and leg pain associated with lumbar spinal stenosis. However, little is known about which patient characteristics may predict favorable responses. ⋯ Among 21 baseline patient characteristics examined, none, including clinician-rated spinal stenosis severity, were consistent predictors of benefit from epidural injections of lidocaine+corticosteroid versus lidocaine only.

Few instruments are available to measure disability associated with whiplash-associated disorders (WAD). The Whiplash Disability Questionnaire (WDQ) was developed to measure disability resulting from WAD, but its validity is unknown for acute WAD. ⋯ The WDQ includes two factors and has strong construct validity in individuals with acute WAD. Our results demonstrate that the WDQ is valid for use as an overall summative scale or as the daily activities and emotional subscales in clinical and research settings to determine disability status.
