Purpose : To evaluate the accompanying abnormal findings of Schmorl's nodes(SN), a
normal variant of the lumbar spine.
Materials and Methods : Seventy-five patients with one or more SN, as seen on
lumbar spine MRI were studied. Using a 1.5T MR unit, the number and location of SN,
their site on the end plate, adjacent disc changes and lesions associated and not
associated with SN, and accompanying associated bony spinal stenosis were
retrospectively investigated.
Results : Among the 75 patients, 230 SN were noted in 375 vertebral bodies ; they
were relatively frequently located on the second (65, 28.3%) and third (65, 28.3%) lumber
vertebrae. The most common end-plate site of SN was the posterior one-third portion
(160 ; 69.6%). In 450 discs of these 75 patients, 172 lesions were noted ; those
associated with SN (76/167, 45.5%) were more common than those not thus associated
(96/283, 33.9%)(p<0.05), and those associated with SN were relatively frequently located
on intervertebral disc L2-3, or L3-4(p<0.05). Thirty-seven SN (16.1%) were associated
with bony spinal stenosis.
Conclusion : Because it is frequently associated with disc lesions and bony spinal
stenosis, SN of the lumbar spine may be a pathologic condition rather than a normal
variant.
