RESUMEN
The sacroiliac joint is a source of pain in the lower back and buttocks in approximately 15% of the population. Diagnosing sacroiliac joint-mediated pain is difficult because the presenting complaints are similar to those of other causes of back pain. Patients with sacroiliac joint-mediated pain rarely report pain above L5; most localize their pain to the area around the posterior superior iliac spine. Radiographic and laboratory tests primarily help exclude other sources of low back pain. Magnetic resonance imaging, computed tomography, and bone scans of the sacroiliac joint cannot reliably determine whether the joint is the source of the pain. Controlled analgesic injections of the sacroiliac joint are the most important tool in the diagnosis. Treatment modalities include medications, physical therapy, bracing, manual therapy, injections, radiofrequency denervation, and arthrodesis; however, no published prospective data compare the efficacy of these modalities.

Laboratory investigations for neck pain play a minor role in most cases. When clinical suspicion of infection or tumor arises, however, laboratory testing can provide definitive information to direct the patient's care. Specialized laboratory testing including autoantibody titers can be useful in confirming and categorizing inflammatory arthritides. Judicious use of laboratory tests greatly enhances the physician's ability to provide appropriate care.
