Objective:
We investigated the indirect puncture method using a novel arc puncture-guided device in percutaneous transforaminal puncture to improve puncture accuracy and reduce the fluoroscopy, puncture, and operation times.
Methods:
We have designed a novel arc puncture-guided device consisting of a 90° arc block and a 30° arc block. Punctures were performed on 8 fresh goat lumbar spine specimens. A senior doctor performed indirect punctures on the left side of the L2-L3, L3-L4, and L4-L5 levels using the novel device (group A) and on the right side of the L2-L3, L3-L4, and L4-L5 levels using the conventional method (group B). We recorded the fluoroscopy, puncture, and operation times.
Results:
In group A, the first puncture could successfully reach the target after 1-3 punctures, and the one-time success rate of the second needle puncture was 91.67%. The total fluoroscopy time was 14.88 ± 0.99 minutes in group A and 16.08 ± 2.22 minutes in group B (P = 0.027). The puncture times were 3.00 ± 0.66 minutes in group A and 6.04 ± 2.13 minutes in group B (P < 0.01). The operation time was 273.75 ± 30.19 minutes in group A and 361.25 ± 69.57 minutes in group B (P < 0.01). The differences in fluoroscopy times, puncture times, and operation times between the 2 groups were statistically significantly (P < 0.05).
Conclusions:
Indirect puncture using the novel arc puncture-guided device for percutaneous transforaminal puncture can significantly improve puncture accuracy and reduce the fluoroscopy, puncture, and operation times. Indirect puncture using the novel device in percutaneous transforaminal endoscopic discectomy is a potential and practical puncture method.
