[Endoscopic transforaminal lumbar decompression, bone graft fusion and pedicle screw fixation under X-tube system: report of 42 cases].

Abstract

OBJECTIVE:

To evaluate the surgical procedure of unilateral transforaminal discectomy, bone grafting, cage (Telamon) insertion and Dylanok pedicle screw fixation using X-tube operation system for the treatment of lumbar disc herniation combined with segmental instability and Spondylolysis with pars defect.

METHODS:

From 2004 to 2006, 42 patients including 17 male and 25 female were treated in our department. The age range from 22 to 77 (mean: 51.6). Etiologies including lumbar disc herniation combined with segmental instability and Spondylolysis with pars defect.

RESULT:

Of these 42 patients, the mean operation time was 240 min (110 - 320 min), the average blood loss was 140 ml (80 - 420 ml), the average incision length was 3 cm (2.8 - 3.2 cm) and the average hospitalization time was 12.5 days (5 - 25 days). Nakai criteria, Excellent in 23 cases (62.2%), good in 11 cases (29.2%) and fair in 3 cases (8.6%). 5 patients had postoperative complication (complication rate: 16.3%).

CONCLUSIONS:

The surgical procedure has shown predominant benefits: small incision, less stripping of paraspinal muscles, minimal blood loss and rapid postoperative recovery which makes it a valuable alternative to conventional surgical procedures.
