Abstract

STUDY DESIGN: This is a retrospective study analyzing 73 patients treated by decompression, pedicular screw instrumentation and posterior lumbar interbody fusion (PLIF) for lumbosacral spondylolithesis and symptomatic spinal stenosis. we used laminected laminar and spinous process instead of iliac bone.
OBJECTIVES
This is to evaluate fusion rate and clinical results of PLIF with laminected laminar and spinous process.
MATERIALS AND METHODS
PLIF in 73 patients with lumbosacral disorders who carried out at Pohang St. Mary's Hospital from March 1994 to January 1996. Fusion rate was evaluated by simple X-ray and dynamic view. Clinical effect was evaluated by Kirkaldy-Willis criteria.
RESULTS
The solid fusion was achieved at 67 cases(91.8%) and the average period of fusion was 6.4 months. Complications were 2 cases of superficial skin infection and 3 cases of root irritation. The functional results by Kirkaldy-Willis were as follows ; excellent 40 cases, good 23 cases, fair 9 cases and poor 1 case.
CONCLUSIONS
This PLIF procedure combined with transpedicular instrumentation showed sufficient fusion rate and excellent clinical results and improvement in vertebral alignment.
