Objective : There has been a lack of enthusiasm for posterior lumbar interbody fusion(PLIF) in revision surgery. PLIF in revision surgery requires more excessive distraction of neural structures and excessive removal of the facet-laminar structure which plays a significant mechanical role. especially in rotatory stability. The author reports facetolaminoplastic PLIF which provides safe and effective PLIF and even natural circumferential fusion as well.
Patients and Methods : This study consistes of 6 patients. The facetolaminotomy was performed by osteotomizing bilateral pars interarticularis with a Gigli saw. PLIF was performed through more widely exposed intervertebral space by inserting a pair of carbon fiber cages and medial iliac bone blocks between the cages. The facetolaminotomy flap was returned to the previous site and was fixed by trans-laminar and trans-isthmic screw fixation. Bilateral facet arthrodesis was also performed.
Results : There were no neural complications related to facetolaminotomy nor were there any complications related to the screw fixation for the restoration of the posterior construct. Of these 6 cases, radiological union at the interbody fusion site and at both pars interarticularis was noted in 5 cases at a 6-month postoperative follow-up. An incomplete union at unilateral pars interarticularis was noted in remaining one case.
Conclusions : The PLIF by facetolaminoplasty in revision surgery not only provides a wide interspace for safe and effective PLIF but also restores the posterior constructs, thereby preserving its important mechanical roles and often even achieving natural circumferential arthrodesis.
