Abstract:
From March 1990 to February 1992, 40 cases of lumbar spondylolisthesis underwent transpedicle fixation and fusion using VSP system and PWB system. The diagnosis were isthmic types in 17 cases(male;9, female;8) and degenerative types in 23 cases(male;5, female;18), ranging in ages from 34 to 68 years with a mean age of 52 years. The preoperative slip measured less than 20% in 11 cases, between 20 and 40% in 27 cases and more than 40% in 2 cases. At an average 19 months follow up(range;9~33months), the degree of slip correction averaged 43% in isthmic group, 51% in degenerative group, a solic fusion based on radiologic evaluation was achieved in 85%. Overall results showed 77% good, 18% fair and 5% poor. Complications included superficial infection in 2 cases, screw breakage in 1 case and screw loosening in 2 cases.
