    Area of Science:

    • Neurosurgery
    • Biomaterials Engineering
    • Orthopedic Surgery

    Background:

    • Postoperative perineural adhesions are a common cause of failed lumbar disc surgery.
    • Previous methods to prevent adhesions include muscle, fat, gelatin sponge, silicone, and steroids.

    Purpose of the Study:

    • Introduce a novel implantable silicone device, the lumbar shield.
    • Evaluate the efficacy of the lumbar shield in preventing adhesions and improving surgical outcomes.

    Main Methods:

    • The lumbar shield provides a radiopaque marker for recurrent disc herniation detection.
    • It facilitates access for revision surgery and prevents adhesions between dura, nerve root, disc, and muscles.
    • A study involved 82 patients (59 routine, 23 medicolegal) followed for 6 months.

    Main Results:

    • Satisfactory results were achieved in 85% of routine patients at 1 month, 97% at 3 months, and 95% at 6 months.
    • The device aids in diagnosing recurrent disc herniation via X-ray.
    • The lumbar shield successfully prevented adhesions.

    Conclusions:

    • The lumbar shield is a promising device for preventing postoperative perineural adhesions in lumbar disc surgery.
    • It improves patient outcomes and facilitates the management of recurrent disc herniations.
