Thirty patierıts with severe lumbar degenerative spondylolisthesis were treated surgically between August 1991 and December 1995 in Orthopaedics and Traumatology Department of Ege University Medical Faculty. 21 of the patients were female, and 9 were male; the mean age was 42 (29-62) years, The Iow back and leg pain was moderate in 8 patients and severe in 22; seventeen patients had varying degrees of neurologic deficit.

The mean value of slippage was 36.06% (25-55%) and the mean slipping angle was 3.02° (-18°-+15°).

Posterolateral segmental fusion combined with external fixation by pedicular screw and rod system was applied in ali cases. Autolog cancellous bone obtained from the iliac crest in 18 cases and dehydrated spongiosa chips allograft was used in 12 cases. The mean follow-up time was 25 (18-39) months. The low back pain was diminished in 26 patients (87%); neurologic deficit was reduced in fifteen patients (50%). Solid fusion was obtained in 24 patients (80%).

In conclusion, pedicular fixation with posterolateral segmental fusion by allograft or autogenous graft is a preferable method for the surgical treatment of degenerative spondylolisthesis.
