    Summary

    A new method for selecting low-back pain patients for surgery improves outcomes. Objective criteria reduce unnecessary procedures and enhance early surgical results for sciatica patients.

    Area of Science:

    • Neurosurgery
    • Orthopedics
    • Spinal Surgery

    Background:

    • Low-back pain and sciatica are common debilitating conditions.
    • Lumbar discectomy is a surgical option for severe cases.
    • Patient selection for discectomy can be challenging, leading to variable outcomes.

    Purpose of the Study:

    • To present a reproducible, objective method for selecting patients with low-back pain and sciatica for lumbar discectomy.
    • To improve the accuracy of diagnosing herniated nucleus pulposus.
    • To reduce negative disc explorations and enhance early surgical results.

    Main Methods:

    • Developed a selection method based on four objective criteria: neurologic signs, sciatic tension signs, personality factors (MMPI scores), and lumbar myelography.
    • Applied the method to select 50 consecutive patients for lumbar discectomy.
    • Compared operative findings with historical data from patients operated on before the method's implementation.

    Main Results:

    • Complete nucleus pulposus herniation was found in 43 of 50 patients (86%) selected using the new method.
    • This contrasts with complete herniation in only 5 of 26 patients (19%) operated on prior to the method.
    • The objective preoperative evaluation significantly reduced negative disc explorations.

    Conclusions:

    • The presented objective preoperative evaluation method is reproducible and effective for selecting patients for lumbar discectomy.
    • This method improves diagnostic accuracy and enhances early surgical outcomes.
    • Recommended for use in patients considered for elective lumbar discectomy to optimize treatment decisions.
