Intervertebral disc and facet joints are the two primary load-bearing structures of the lumbar spine, and altered loading to these structures may be associated with frontal plane spinal deviations. ⋯ Facet loading increased during simulated pelvic obliquity in frontal and transverse planes, whereas intradiscal pressures were decreased compared with sagittal and frontal plane motions alone. Altered spinopelvic alignment may increase the loads experienced by spinal tissue, especially the facet joints.

Spine-related health-care expenditures accounted for $86 billion dollars in 2005, a 65% increase from 1997. However, when adjusting for inflation, surgeons have seen decreased reimbursement rates over the last decade. ⋯ Based on this analysis, the proportion of overall costs allocated to professional fees for a noninstrumented lumbar laminectomy is small, whereas those allocated to hospital costs are far greater. These findings suggest that the current focus on decreasing physician reimbursement as the principal cost saving strategy will lead to minimal reimbursement for surgeons without a substantial drop in the overall cost of procedures performed.

Pain innate to intervertebral disc, often referred to as discogenic pain, is suspected by some authors to be the major source of chronic low back and neck pain. Current management of suspected discogenic pain lacks standardized diagnosis, treatment, and terminology. ⋯ Our findings show that suspected discogenic pain, despite its extensive affirmation in the literature and enormous resources regularly devoted to it, currently lacks clear diagnostic criteria and uniform treatment or terminology.

Accurate measurement of functional improvement in clinical practice is becoming increasingly recognized as essential in demonstrating whether patients are deriving meaningful benefit from care. Several simple questionnaires have been developed for this purpose. The majority of these have been developed in English. In North America, there is a growing need for clinical tools, including outcome assessment tools that are available in the Spanish language. ⋯ Several reliable and valid outcome assessment questionnaires are available in the Spanish language. All were originally developed in English. It appears from the data reviewed that the most useful instruments are the NDI for neck pain patients and the ODI and RMQ for low back pain patients. The current trend is for the development of culturally adapted versions of these questionnaires that are specific to a particular country or region.

Intractable cervical radiculopathy secondary to stenosis or herniated nucleus pulposus is commonly treated with an anterior cervical decompression and fusion (ACDF) procedure. However, there is little evidence in the literature that demonstrates the impact such surgery has on long-term range of motion (ROM) outcomes. ⋯ Our results suggest that patients who have had an ACDF for cervical radiculopathy will experience improved ROM 6 months postoperatively. In addition, patients can expect a decrease in pain, an improvement in neck function, and a decrease in headache frequency.
