T-laminoplasty--a surgical approach for cervical spondylotic myelopathy. Technical note.

The T-laminoplasty allows for a generous decompression of the cervical canal. At the same time, it avoids the risk of late instability. The T-laminoplasty is an improvement over various other methods of laminoplasty for several reasons: 1. A bone graft from donor site is not needed. 2. The implanted bone graft is firmly secured, avoiding dislocation and compression of the spinal cord. 3. A fusion of two segments becomes unnecessary. 4. Implants (metal or bone) are not needed.
