AIM: To find out the efficacy, security, and medical worth of a novel surgical process involving the blunt perforation of the ligamentum flavum (LF) throughout endoscopic interlaminar lumbar discectomy.
MATERIAL AND METHODS: This was a potential research of 50 sufferers (27 males, 17-51 years of age) present process lumbar discectomy for single section L4/L5 or L5/S1 disk herniation had been grouped into the management (reducing of the LF; n=28) and take a look at (blunt perforation; n=22) teams. Intraoperative harm to the LF was evaluated by electrophysiological monitoring. The time required for perforation, complete surgical time, and proportion of epidural sac and nerve root harm had been assessed.
RESULTS: Among the many enrolled sufferers, 90% confirmed herniation of the L4/5 section and 10% of the L5/S1 section. The success fee for the perforation of the LF was 93%. The intraoperative statement confirmed gentle self-closing harm to the LF tissue. The take a look at group confirmed shorter total surgical time (43 vs. 56 min) and shorter length to undergo the LF (1 vs. 13 min, p zero.001). No dural sac or nerve root harm ensuing from blunt perforation of the LF was noticed.
CONCLUSION: In comparison with reducing, blunt perforation of the LF might scale back surgical time and harm to LF and surrounding tissues. Thus, it may very well be a secure and environment friendly surgical approach for sufferers present process intralaminar lumbar discectomy.
