Abstract

Objectives: Between the group where the conventional posterior lumbar interbody fusion (PLIF) was performed using microscope and the open transpedicular screw fixation system and that where mini-open PLIF was performed using the newly-designed percutaneous transpedicular screw fixation system characterized by vertical axis and detachable screw extender system, the surgical outcome was compared. Thus, attempts were made to analyze the usefulness of vertical axis and detachable screw extender system. Methods: During a period ranging from January 2004 to February 2007, the surgical outcome was compared between the group where the conventional posterior lumbar interbody fusion (PLIF) was performed using microscope and the open transpedicular screw fixation system and that where mini-open PLIF was performed using the newly-designed percutaneous transpedicular screw fixation system (Apollon system, Solco medical, South Korea) characterized by vertical axis and detachable screw extender system. The number of cases in which the conventional PLIF was performed was 86 (Group A) and that of those in which the mini-open PLIF was performed was 145 (Group B). In the Group A, mean followup period was 23.7 months (6 months to 43months) and mean age was 56.3 (34 to 73) years. In regard to the level, one level was seen in 73 cases, two levels were seen in 11 cases and three levels were seen in 4 cases. In the Group B, mean follow-up period was 25.3 months (6 months to 43months) and mean age was 59.1 (23 to 78) years. In regard to the level, one level was seen in 117 cases, two levels were seen in 22 cases and three levels were seen in 6 cases. Clinical outcome was assessed using last clinical follow up Low Back Outcome Score (LBOS). We also compared the operation time, intra-operative bleeding loss, postoperative surgical scar and complications. Results: In the Group A, mean surgical time was 163.7 minutes (120-280 minutes), bleeding loss was 753 ml (350-1200ml) and average LBOS was 56.2. The levels of postoperative surgical scar were as follows: one level: 6.23 Cm, two levels: 11.28Cm and three levels: 15.26Cm. Complications include five cases (5.8%) of dural tear, four cases (4.7%) of deep wound infection and four cases (4.7%) of device failure and fusion failure. In the Group B, mean surgical time was 142.6 minutes (100- 240minutes), bleeding loss was 438 ml (160-850ml) and average LBOS was 63.8. The levels of postoperative surgical scar were as follows: one level: 3.71 Cm, two levels: 6.27 Cm and three levels: 8.35Cm. Complications include eight cases (5.5%) of dural tear, four cases (2.7%) of deep wound infection and five cases (3.4%) of device failure and fusion failure. Conclusions: Vertical Axis and detachable Screw Extender System makes it easier to perform rod manipulation as well as compression and distraction. As compared with conventional PLIF, it can diminish midline skin incision. It is therefore useful in reducing operation time and intra-operative bleeding loss, thus minimizing the postoperative occurrence of back pain and complication. Accordingly, a prompt recovery and a good clinical outcome can be expected.
