Vertebroplasty (VP) and kyphoplasty (KP) are routinely used to treat vertebral body compression fractures (VCFs) resulting from osteoporosis or vertebral body tumors in order to provide rapid pain relief. However, it remains debated whether VP or KP results in superior outcomes versus medical management alone in patients experiencing VCFs. ⋯ Although evidence suggests that physical disability, general health, and pain relief are better with VP and KP than those with medical management within the first 3 months after intervention, high-quality randomized trials with 2-year follow-up are needed to confirm this. Furthermore, the reported incidence of symptomatic procedure-related morbidity for both VP and KP is very low.

Consensus documents have recently been developed enumerating the radiographic parameters thought to be most valid in the clinical evaluation of patients with thoracolumbar fractures. ⋯ This study demonstrates that Cobb angle measurement, Gardner segmental deformity angle, and anterior body compression percentage are reliable measures of thoracolumbar fracture kyphosis with very high interobserver and intraobserver reliability and very high inter-modality agreement of plain X-ray with CT.

Degenerative spondylolisthesis has been well described as a disorder of the lumbar spine. Few authors have suggested that a similar disorder occurs in the cervical spine. To our knowledge, the present study represents the largest series of patients with long-term follow-up who were managed surgically for the treatment of degenerative spondylolisthesis of the cervical spine. ⋯ Degenerative spondylolisthesis is relatively common in the cervical spine. Common to all cases is facet arthropathy and neurologic compression. Anterior cervical decompression and arthrodesis appears to yield excellent union rates and neurological improvement in those patients having cervical degenerative spondylolisthesis and significant neurological sequelae who have failed nonoperative treatments.

Epidural injections are commonly used to treat low back disorders. It has been proposed that in addition to the anti-inflammatory effects, injected material displaces the dura forward and inward, producing a stretch of the nerve roots that leads to lysis of neural adhesions. Despite this, there are no controlled trials investigating the effect of volume injected with pain as an independent outcome. ⋯ These preliminary results suggest a positive correlation between larger volumes of fluid injected in the epidural space and greater relief of radicular leg pain and/or low back pain. Clinicians should not change their practice, until further high-quality clinical studies confirm these findings.

Questionnaires for measuring the functional status of patients with low back pain (LBP) focus on disability and present responses for each question in a predetermined, fixed relationship between "can do/difficulties and pain." Their design does not permit a separation of the two. ⋯ The construction of the POP allows the patient to count, and the occupational therapist to investigate, from full level of activity to avoidance and from no pain to worst imaginable pain for each physically loaded task in personal activities of daily living (ADL), transfer/transport, instrumental ADL, and social activities. The POP can differentiate between groups concerning level of activity and pain, and appears to be a valid and reliable instrument for evaluating LBP. The POP should be considered for use in both clinical and research applications.
