ABSTRACT
STUDY DESIGN:
Retrospective cohort study at a single institution.OBJECTIVE:
To examine the effect of symptom duration on clinical outcomes after posterolateral lumbar fusion. SUMMARY OF BACKGROUND DATA Nonoperative measures are generally exhausted before patients are indicated for surgical intervention, leaving patients with their symptomatology for varying lengths of time. It is unclear at what point in time surgical intervention may become less efficacious at alleviating preoperative symptoms. MATERIALS ANDMETHODS:
Consecutive patients who underwent primary elective open posterior lumbar spinal fusion at a single academic institution were included. Patient and operative characteristics were compared between symptom duration groups (group 1 <12 mo of pain, group 2 ≥12 mo of pain). Preoperative and final postoperative visual analog scale back/leg pain, and Oswestry Disability Index, were collected. Preoperative, immediate postoperative, and final radiographs were assessed to measure lumbar lordosis (LL), pelvic tilt (PT), pelvic incidence (PI), and the PI-LL difference was calculated.RESULTS:
In total, 167 patients were included in group 1, whereas 359 patients were included in group 2. Baseline demographics and operative characteristics were similar between the 2 groups. Both groups had similar changes in sagittal parameters and had no significant difference in rates of complication, reoperation, discharge to rehabilitation facility, or early adjacent segment degeneration. Both groups demonstrated similar improvement in clinical outcome measures.CONCLUSIONS:
Despite differences in symptom duration, patients who had pain for ≥12 months demonstrated similar improvement after posterolateral lumbar arthrodesis than those who had pain for <12 months. Extended effort of conservative treatments or delay of operative intervention does not appear to negatively impact the eventual outcome of surgery. LEVEL OF EVIDENCE Level III.
