Determining the presence of comorbid conditions in patients with persistent axial pain after motor vehicle accident (MVA) is important to direct appropriate care and as a public health measure against future traffic injuries. In the clinical care of patients after MVA, they are usually asked about previous axial pain problems and relevant comorbid conditions (psychological distress and drug and alcohol abuse). The accuracy of self-reported previous axial pain history and comorbid conditions after MVA has not been systematically evaluated but has been assumed to be high. ⋯ In patients being seen for continued pain related to an MVA, the validity of self-reported previous axial pain and comorbid conditions appeared poor. The self-reported prevalence of previous axial pain and drug, alcohol, and psychological problems is much less than the documented prevalence in prior medical records. These rates were also markedly below the expected prevalence in age- and sex-matched populations. This effect was seen most prominently in patients perceiving the accident to be another party's fault and in those filing compensation claims. The failure to appreciate previous axial pain problems and drug, alcohol, and psychological problems may compromise patient care and public health opportunities.

The objective of the North American Spine Society (NASS) evidence-based clinical guideline for the diagnosis and treatment of degenerative lumbar spinal stenosis (DLSS) is to provide evidence-based recommendations to address key clinical questions surrounding the diagnosis and treatment of DLSS. The guideline is intended to reflect contemporary treatment concepts for symptomatic DLSS as reflected in the highest quality clinical literature available on this subject as of April 2006. The goals of the guideline recommendations are to assist in delivering optimum, efficacious treatment, and functional recovery from this spinal disorder. ⋯ A clinical guideline for DLSS has been created using the techniques of evidence-based medicine and using the best available evidence as a tool to aid both practitioners and patients involved with the care of this disease. The entire guideline document including the evidentiary tables, suggestions for future research, and all references is available electronically at the NASS Web site (www.spine.org) and will remain updated on a timely schedule.

Penetrating bullets dissipate thermal and kinetic energy into surrounding tissues. Within the thecal sac, this is universally associated with neurological deficits. ⋯ Patients can avoid neurological injury even with an intrathecal gunshot wound. However, intrathecal bullets may then migrate and cause variable neurological complaints, necessitating surgical removal. Patient positioning can influence bullet location which can be useful in surgical planning.

Objective measures including neurological findings, radiographic evaluation, and the Japanese Orthopaedic Association (JOA) score are commonly used for the evaluation of surgical outcomes. Because many surgeries are performed primarily to improve quality of life, a patient's subjective evaluations are also important for accurately assessing surgical outcomes. Currently available instruments for assessing quality of life include the Short-Form 36 (F-36), the Oswestry disability index (ODI), and the visual analog scale (VAS) clinical pain scale. ⋯ The JOA, SF-36, ODI, and VAS questionnaires are all useful instruments for measuring surgical outcomes. The VAS score is a better assessment of physical rather than mental health. The ODI is more reflective of patients' subjective symptoms. Finally, the SF-36 is particularly informative because it includes questions addressing both psychological and physical status. Therefore, when combined, the SF-36v2, VAS, and ODI scores are a valuable complement to the JOA scores in evaluating outcomes of surgery for lumbar canal stenosis.
