Safety and Efficacy of Percutaneous Lumbar Discectomy and Percutaneous Disc Cementoplasty for Painful Lumbar Disc Herniation in Patients over 60 Years.

PURPOSE: To determine the safety and efficacy of percutaneous lumbar discectomy (PLD) and percutaneous disc cementoplasty (PDCP) for painful lumbar disc herniation (LDH) in patients >60 years of age. MATERIALS AND METHODS: Sixteen older patients (mean age, 71.00 ± 6.24 years) with painful LDH were treated with PLD and PDCP. The outcome data (the Macnab criteria, visual analog scale score, and Oswestry disability index) were collected preoperatively; at 1 week postoperatively; at posttreatment months 1, 3, and 6; and every 6 months thereafter. In addition, treatment duration, injection volume of bone cement, length of hospital stay, and complications were assessed. RESULTS: Treatment was successful in all patients. The pain relief rate at the last follow-up was 87.5%. Six, 8, and 2 patients showed excellent, good, and fair results, respectively; no patient showed a poor result. The average visual analog scale for back and leg pain decreased from 6.75 ± 1.06 and 7.00 ± 0.89 before the procedure to 2.81 ± 1.60 and 2.87 ± 1.75 at 1 month, 2.79 ± 1.58 and 2.71 ± 1.64 at 6 months, and 2.90 ± 1.73 and 3.00 ± 1.76 at 1 year, respectively. The scores were 2.44 ± 1.63 and 2.44 ± 1.71, respectively, at the last follow-up. The Oswestry disability index also changed after the procedure, with significant differences between baseline scores and those at each follow-up (P < .001). The mean procedure duration, injection volume of bone cement, and length of hospital stay were 55.69 ± 5.86 minutes, 2.50 ± 0.63 mL, and 7.06 ± 2.41 days, respectively. There were no complications. CONCLUSIONS: The combination of PLD and PDCP is feasible, safe, and effective for older patients with painful LDH.
