[A long-term follow-up of lumbar laminotomy and replantation].
OBJECTIVE
To evaluate lumbar laminotomy and replantation in prevention of spinal unstability and peridural adhesion after laminectomy.


METHODS
From February 1995 to March 2001, a total of 169 patients (96 males, 73 females, aged 22-63) with lesions in the lumbar vertebral canals underwent surgery, in which the lesions were removed after laminectomy and then the excised laminae were replanted.


RESULTS
The follow-up for 5-9 years showed that all the patients had no complications after the lesions were removed. According to the evaluation criteria formulated by WANG Yongti, 81 patients had an excellent result, 67 had a good result, 19 had a fair result, and 2 had a poor result. 87.6% of the patients obtained quite satisfactory results. The X-ray films demonstrated that the replanted laminae obtained bony healing and the spine was stable. The CT scanning demonstrated that the canals were enlarged with a smooth and glossy interior.


CONCLUSIONS
Lumbar laminotomy and replantation is reasonable in design and convenient in performance, which can be promoted as a basic operation in spinal surgery.
