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 examine of 50 sufferers (27 males, 17-51 years of age) present process lumbar discectomy for single phase L4/L5 or L5/S1 disk herniation had been grouped into the management (slicing of the LF; n=28) and take a look at (blunt perforation; n=22) teams. Intraoperative damage to the LF was evaluated by electrophysiological monitoring. The time required for perforation, whole surgical time, and proportion of epidural sac and nerve root damage had been assessed.
RESULTS: Among the many enrolled sufferers, 90% confirmed herniation of the L4/5 phase and 10% of the L5/S1 phase. The success fee for the perforation of the LF was 93%. The intraoperative remark confirmed delicate self-closing damage 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 damage ensuing from blunt perforation of the LF was noticed.
CONCLUSION: In comparison with slicing, blunt perforation of the LF may scale back surgical time and damage to LF and surrounding tissues. Thus, it might be a secure and environment friendly surgical approach for sufferers present process intralaminar lumbar discectomy.
