Abstract

Objective
The purpose of this study was to determine the efficacy of unilateral posterior lumbar interbody fusion(Hemi-PLIF) by using one cage for the patients with focal type of degenerative lumbar diseases.

Materials and Methods
The authors reviewed clinical and radiologic data of 43 patients with focal type of degenerative lumbar diseases who underwent unilateral Hemi-PLIF during the period between November 2000 and June 2003. The operation procedure was unilateral hemi-PLIF using titanium cages with transpedicular screw fixation.

Results
The mean follow-up period was 11.2months. The mean operation time was 197 minutes and the average estimated blood loss was 285ml. The clinical success rate according to Prolo's scale was achieved in 89.3%. of patients and the solid bony fusion was noted in 96.4%. There were 2 postoperative complications, one superficial infection and one screw malposition.

Conclusion
This procedure seems to be an effective and safe procedure with acceptable incidence of complications. When compared with bilateral PLIF, less operation time, less blood loss, more fusion rate were noted as advantages.
