Biomechanical analysis of the interlaminar dynamic stabilization system (IntraSPINE) in unilateral biportal endoscopic discectomy for huge lumbar disc herniation: a finite element study

The IntraSPINE dynamic stabilization system combined with UBE discectomy surgery offers significant biomechanical advantages in the treatment of HLDH. Its unique dynamic stabilization properties can effectively maintain intervertebral height, preserve partial mobility of the operated and adjacent segments, and alleviate postoperative stress concentration on the intervertebral disc and facet joints. Therefore, it may serve as a promising treatment option for HLDH patients.
