Objective

Aim of this investigation was to compare the osseous fusion rate in patients following dorsal instrumentated stabilization in degenerative lumbar spondylolisthesis using interbody cages or autogenous bone grafts.

Methods

Over a period of 28 months 58 consecutive patients (35 female, 23 male, median age 59y, range 23 to 80y) with degenerative lumbar spondylolisthesis (Meyerding grade 1 and 2) were stabilized with pedicle srew fixation. Interbody fusion was performed with a cage in 35 patients, in 23 patients we used autogenous bone graft collected from spinous process and lamina resection. Osseous fusion rate was measured by radiography and CT scan 12±2 months after surgery.

Results

The evaluation of radiographic and CT data revealed a overall fusion rate of approx. 80%. Significant differences between cage and bone graft fusion were not detectable. Time of surgery in bone graft fusion was shorter.

Conclusions

Autogenous bone graft fusion in dorsal instrumentated degenerative lumbar spondylolisthesis using donor bone from the surgical approach is a time and cost sparing method. The osseous fusion rates are comparable to cage interbody fusion.
