Abstract

|
The main aims of surgery for severe cord compression and myelopathy caused by atlantoaxial subluxation are decompression of the spinal cord and achievement of rigid fixation and fusion. Direct decompression by resecting the bony structures that compress the spinal cord includes transoral decompression and resection of the posterior arch of the atlas. The shortcomings of these procedures are a high complication rate and a relatively low rate of union. Indirect decompression can be performed by a reduction of the subluxation and fixation without bone resection. To the best of our knowledge, there are no domestic reports on the use of indirect decompression for severe cord compression and myelopathy for atlantoaxial subluxation. We report a case of a patient that had atlantoaxial subluxation and severe myelopathy; satisfactory reduction of the subluxation and decompression with an improvement in the myelopathy symptoms was achieved by indirect decompression using segmental screw fixation.
