ABSTRACT
STUDY DESIGN:
A retrospective study to evaluate the results of posterior lumbar interbody fusion (PLIF) using titanium cages filled with morselized local bone.OBJECTIVE:
To verify the clinical and radiological results of the PLIF procedure using rectangular titanium cages filled with morselized local bone. SUMMARY AND LITERATURE REVIEW Stabilization of the spine can be achieved by interbody arthrodesis through the posterior approach. However many significant problems including bone graft collapse, resorption, nonunion, and iliac donor site morbidity caused by the classic PLIF procedure need to be solved. The use of local bone and a titanium cage might be a solution. MATERIALS ANDMETHOD:
Fifty-nine patients(average age at surgery, 51.3 years), who underwent surgery for degenerated low back disease, were enrolled in this study. The average follow-up duration was 19.9 months. The radiological fusion status, intervertebral disc heights, visual analogue scales, clinical outcomes were evaluated.RESULTS:
Forty-three (73%) patients were classified as complete-union, 16 (27%) patients as probable-union, and no patients were classified as non-union. The average intervertebral disc height increased by 3.7 mm at immediate postoperatively, and the average subsidence was 1.1 mm at the final follow-up. The average visual analogue scale decreased from 5.5 to 1.4 for back pain and from 6.6 to 0.8 for radicular pain. Nineteen (32%) and 28 (48%) patients were classified as excellent and good, respectively, according to clinical outcome assessment by Kim and Kim criteria. The complications encountered were a dural tear in 8 patients, partial root injury in 1, and upper adjacent segment instability during follow-up in 2.CONCLUSION:
PLIF using titanium cages filled with morselized local bone has the advantages of maintaining an intervertebral disc height, immediate stability, and the avoidance of donor site morbidity. However, longer-term results are needed, because the follow-up period of this study was relatively short
