Diastematomyelia is a rare congenital abnormality of the spinal cord. This paper summarises more than 30 years' experience of treating this condition. Data were collected retrospectively on 138 patients with diastematomyelia (34 males, 104 females) who were treated at our hospital from May 1978 to April 2010. ⋯ Radiographs, CT myelography, and MRI showed characteristic kyphoscoliosis, widening of the interpedicle distance, and bony, cartilaginous, and fibrous septum. The incidences of symptoms including characteristic changes of the dorsal skin, neurological disorders, and congenital spinal or foot deformity were significantly higher in type 1 than in type 2. Surgery is more effective for patients with type 1 diastematomyelia; patients without surgery showed no improvement.

Posterior lumbar interbody fusion using spinous process and laminae.
Posterior lumbar interbody fusion (PLIF) is indicated for many patients with pain and/or instability of the lumbar spine. We performed 36 PLIF procedures using the patient's lumbar spinous process and laminae, which were inserted as a bone graft between two vertebral bodies without using a cage. ⋯ There were no serious complications. These results suggest that this procedure is safe and effective.
