Intralaminar Lumbar Microendoscopic Discectomy

Microendoscopic Technique:

• • Microendoscopy refers to using a small camera (endoscope) and specialized surgical instruments to perform the surgery. The endoscope provides the surgeon with a clear, magnified view of the spinal structures.
  • The instruments used are much smaller compared to traditional surgical tools, leading to a minimally invasive procedure with smaller incisions and less disruption to surrounding tissues.
  • The procedure is performed through a small incision, often less than an inch long, which reduces muscle and tissue trauma compared to traditional open surgery.

• Procedure:

  • Preparation: The patient is typically placed under general anesthesia. The surgeon marks the area to be treated using imaging techniques like X-rays or MRI scans.
  • Accessing the Spine: A small incision is made in the skin over the affected area of the lumbar spine. The surgeon carefully dilates the muscles and tissues to reach the spinal canal, without cutting or damaging large muscle groups.
  • Removing Disc Material: Through the endoscope, the surgeon can visualize the herniated disc and the nerve roots. Using specialized instruments, the herniated or bulging portion of the disc is removed, relieving pressure on the nerve.
  • If necessary, small portions of the lamina (bone) may be removed to provide better access to the herniated disc.

• Benefits of ILMED:

  • Minimally Invasive: The small incision and reduced muscle dissection lead to less tissue damage, a lower risk of complications, and a faster recovery.
  • Reduced Post-Operative Pain: Since the procedure is less invasive, many patients experience less postoperative pain and a quicker recovery compared to traditional open surgery.
  • Shorter Hospital Stay: Most patients are able to go home on the same day or the day after surgery.
  • Faster Recovery: ILMED patients often return to daily activities sooner than those who undergo traditional surgery.

• Indications for ILMED:

  • It is generally recommended for patients with lumbar disc herniations that cause nerve compression, leading to pain, numbness, or weakness in the legs (sciatica).
  • It may be considered for patients who have not responded well to non-surgical treatments (e.g., physical therapy, medications, injections) and have a well-defined herniation that can be treated via the minimally invasive approach.

• Recovery:

  • Postoperative Care: After the procedure, patients may experience some soreness at the incision site, but most people have significantly reduced leg pain or numbness shortly after the surgery.
  • Physical Therapy: A course of physical therapy may be recommended to strengthen the muscles of the lower back and improve mobility.
  • Most patients can return to light activities within 1 to 2 weeks, with full recovery taking anywhere from a few weeks to a couple of months, depending on individual healing.
