    Diagnosing lumbar nerve lateral entrapment is now more accurate with Computed Tomography scans. Surgical treatment offers significant pain relief and return to work for many patients.

    Area of Science:

    • Neurosurgery
    • Orthopedic Surgery
    • Radiology

    Background:

    • Lumbar nerve lateral entrapment was historically difficult to diagnose preoperatively.
    • Diagnosis relied on clinical findings and radiographs showing disc resorption.
    • Computed Tomography (CT) has significantly improved diagnostic accuracy.

    Purpose of the Study:

    • To evaluate the diagnostic utility of CT scans for lumbar nerve lateral entrapment.
    • To assess the efficacy of surgical intervention for refractory cases.
    • To analyze patient outcomes including pain reduction and return to occupation.

    Main Methods:

    • Utilized Computed Tomography (CT) for definitive diagnosis.
    • Performed bilateral minimal partial laminectomy with superior articular process resection.

  • Employed free fat grafts to prevent dural adhesions.
  • Managed instability with posterolateral fusion based on stress radiographs.

    • Main Results:

    • Marked improvement in 62% of patients, slight improvement in 21%.
    • 17% of patients remained unimproved post-surgery.
    • 62% reported no or mild pain.
    • 66% of patients resumed their previous occupations.

    Conclusions:

    • CT scans provide accurate diagnosis of lumbar nerve lateral entrapment.
    • Surgical treatment, including laminectomy and fusion when necessary, yields positive outcomes.
    • The procedure effectively alleviates pain and facilitates return to work.
