증례 / 흉요추 이행부 원인에 의한 후장골릉 부근 요통

Pain around the posterior iliac crest area is usually attributed to disorders of the lower lumbar or lumbosacral spine. However, low back pain arising from the thoracolumbar region is common and it is very similar to low back pain of lumbosacral origin. Low back pain of thoracolumbar origin is clinically distinguished from other nonspecific low back pain syndrome. It is characterized by symptoms localized at one posterior iliac crest innervated by posterior branch of Tu spinal nerve. Patients never complain of T12 spontaneous pain at the thoracolumbar junction. Only localized tendemess over involved segments of thoracolumbar junction can be noted. We report two cases of posterior iliac crest pain of thoracolumbar origin which was relieved by the treatment on the thoracolumbar junction.
