Abstract：Objective To investigate the clinical outcomes and surgical techniques of percutaneous endoscopic interlaminar approach for calciifed lumbar disc herniation. Methods From November 2011 to June 2013, 56 patients with calciifed lumber disc herniation were adopted, who were then divided into 2 groups. The patients in Group I ( n=28 ) were treated with percutaneous endoscopic interlaminar approach, and the patients in Group II ( n=28 ) underwent traditional open surgery. The assessment was performed using the Oswestry Disability Index ( ODI ), Visual Analogue Scale ( VAS ) and the modiifed Macnab criteria preoperatively and at 1 day, 3 months and 6 months after the operation. The parameters were recorded such as the operation time, intraoperative blood loss, amount of removed bone, postoperative complications, hospital stays and so on. Results The surgical results in both groups were satisfactory. The preoperative VAS scores were 7.36±0.29 points in Group I, which were signiifcantly improved to 3.52±0.23, 2.99±0.11 and 3.15±0.19 points at 1 day, 3 months and 6 months after the surgery. The preoperative VAS scores were 7.29±0.28 points in Group II, which were signiifcantly improved to 4.02±0.23, 3.48±0.13 and 3.03±0.04 points at 1 day, 3 months and 6 months after the surgery. The preoperative ODI scores were 70.18±1.63 points in Group I, which were decreased to 34.24±1.39, 32.84±1.38 and 33.33±1.40 points at 1 day, 3 months and 6 months after the surgery. The preoperative ODI scores were 69.82±1.31 points in Group II, which were decreased to 36.51±1.39, 33.50±1.50 and 32.48±2.87 points at 1 day, 3 months and 6 months after the surgery. No obvious differences in the VAS score and ODI score at 6 months after the surgery were noticed between the 2 groups ( P=0.34, P=0.80 ). According to the MacNab criteria, the excellent and good rates were 96.4%and 92.9%, without statistically signiifcant differences between the 2 groups ( P=0.62 ). When it came to the intraoperative blood loss, amount of removed bone and hospital stays, Group I was signiifcantly superior to Group II ( P<0.001 ). The operation time in Group I was 52.93±6.66 min, which was longer than 41.79±7.85 min in Group II ( P<0.001 ). In terms of the postoperative complications, 2 patients had lower limb numbness and 1 patient experienced dural tear in Group I, whereas, 1 patient had lower limb numbness in Group II. All the 4 patients were treated conservatively and recovered, and there was no permanent nerve root injury or aggregation. Conclusions The clinical outcomes of percutaneous endoscopic interlaminar technique are equal to that of traditional open surgery in the treatment of calciifed lumbar disc herniation, with the advantages of less tissue injury and reduced operation time and rehabilitation period. All in all, percutaneous endoscopic interlaminar technique is worthy of clinical application.
