Neurological recovery after posterior decompression surgery for anterior dural compression in paralytic spinal metastasis

摘要

Purpose Paralysis in spinal metastasis is often caused by anterior dural compression, and anterior approach has been frequently chosen for decompression despite its dreadful complications. On the other hand, the effectiveness of posterior indirect decompression has not specifically established. The objective of the present study was to investigate the anatomical patterns of dural compression, and to clarify the effectiveness of posterior surgery for anterior lesions.
