Methods• Study period March 1997 to November 2003• 226 patients underwent PLIF• 182 patients have both baseline & follow-up
(80% response)• Outcomes measured at baseline (pre-op) and at
a single follow-up (post-op)• Mean follow up – 26 months

Outcome Measures
• Oswestry disability index (ODI)*• VAS for back and leg pain• SF-36
*9 section NASS ODI used, with each section scored 0-5 www.spinalunit.org.
Patients• 182 patients
– 99 females– 83 males
• Mean age = 45.3 yrs• 110 one level fusion• 72 two level fusion• Duration of
symptoms- median 63 months

Summary
• ODI- 45% improvement
• VAS Back- 51% improvement
• VAS Leg- 50% improvement
• SF-36- 12-69% improvement
Complications
• Dural tear- 12 • Neuralgia- 16→ 6 persistent leg pain• Infection-
– Superficial-8, Deep-2.• Bone graft pain- 3• Pedicle fracture- 2• Brachial neuropraxia- 1

Clinical Results
• 68% of patients had significant improvement in Oswestry scores (>15%).
• 79% of patients had significant decrease in VAS for Back pain (change >2 points).
• 68.3% of patients had significant decrease in VAS for leg pain (change>2 points).

Conclusion
PLIF surgery reduces pain, improves functioning and quality of life in patients with chronic low back & leg pain, unresolved by
conservative therapy

Further Advancement
• Our current technique involves less invasive surgery and results are much better than the results presented.
• We will present these results in a future meeting.
