This is a report on four cases of delayed myelopathy following compression fractures of the thoraco-lumbar spine. Cases 1, 2, and 3 developed myelopathy in a relatively short period of time of 6, 2 and 3 months following the fractures respectively. Although these three cases showed stable fractures on radiographs immediately after the injury, there were bulging features on the posterior margin of the vertebral body. Correction of kyphotic deformity, decompression and anterior fusion were indicated for the cases with destruction of anterior stabilizing mechanism. We obtained excellent result in these three cases through this method. Case 4. showed compression myelopathy caused by ossification of yellow ligament (OYL) with occurred at the site of compression fracture. In this case, the kyphotic deformity after fracture secondarily caused the neurological symptoms due to OYL.
