Review paper of outcome studies among primary care back pain patients. ⋯ Results from existing studies suggest that back pain among primary care patients typically runs a recurrent course characterized by variation and change, rather than an acute, self-limiting course.

Bone SPECT imaging offers advantages over planar techniques based on improved contrast enhancement plus tomographic effect, with the latter allowing for precise anatomic localization of an abnormality. This is important when evaluating patients with back pain because placement of a lesion in the vertebral body, component of the vertebral arch, or disc space region significantly affects diagnostic possibilities and, in some circumstances, can effectively exclude malignancy in favor of benign disease. Such an approach to SPECT interpretation requires high-quality images capable of precise anatomic placement of a lesion and a systematic method of analysis based on recognition of normal anatomic relationships plus knowledge of the common presentations of bony abnormalities shown on SPECT scanning.

The number of available diagnostic tests for patients with back and neck pain has grown dramatically over the past two decades, and their cost has increased as well. The impact of managed care and an increased understanding of the natural history of these conditions have led to close evaluation of the sensitivity and specificity of these tests and their effect on patient outcomes. ⋯ Guidelines for the testing of patients with chronic back and neck pain have yet to be developed. Stronger emphasis on psychosocial issues and the assurance that pathologic progression has not been missed without the use of repetitive testing form the mainstay of diagnostic protocols in this population.

The most important determinant of successful treatment in all spinal disorders is accurate diagnosis. Diagnostic injection procedures, such as facet blocks, selective nerve root blocks, and discography can aid in accurately diagnosing the source of a patient's pain.

Classification of back pain is a difficult task. Traditional schemes have focused on the small percentage of cases which have specific causes. Structural anomalies observed on X-ray examination explain only a small proportion of back pain cases, and the emphasis placed on these in the traditional schemes is, as Anderson put it, the tail wagging the dog (Anderson, 1977). ⋯ More pragmatic approaches start with the separation of the serious from the less serious, and the distinction between spinal pain and pain arising from outside the spine. The classification of the large majority of back pain cases which are 'non-specific' is best approached by grading the severity of the clinical and psychological features of back pain and their disabling consequences. Such grading schemes also provide the most appropriate outcome measures for clinical and epidemiological back pain research.
