Abstract
There are 105 surgically operated cases in our clinic for the lumbar disc lesions between the period of '68 to '73; these are observed for four to sixty two months and reported the end-result datum.
Our surgical techniques are osteoplastic partial facetolaminectomy (Kondo's method) and replaced lamina fixation with the screw nail (Teshima's method). Our laminectomy is the favorable method in that it allows a wide field of surgical operation thus making the operation easier, enabling the surgery to be performed perfectly.
We believe it is necessary to take into consideration of H-graft or Langenskiold's spondylodesis in case of instability of the vertebral body, narrowing of the vertebral disc space, or particulary those who are engaged in hard musclar laborer.
The methods of our laminectomy proved a good result.
