The mild Procedure

What is the mild procedure?

The mild procedure (Minimally Invasive Lumbar Decompression) is a relatively new minimally invasive surgical technique used to treat lumbar spinal stenosis, a condition where the spinal canal narrows and puts pressure on the nerves in the lower back. During the mild procedure, a small incision is made, and specialized tools are used to remove excess bone and tissue, relieving pressure on the affected nerves. Unlike traditional open surgery, the mild procedure typically requires only local anesthesia and sedation, and patients usually experience less pain and a faster recovery time. It’s often considered for those who haven’t found relief from conservative treatments like medication or physical therapy.

The mild procedure is performed with the patient lying face down on an operating table. Here’s a general overview of the steps involved:

  1. Anesthesia: Local anesthesia is administered to numb the area where the procedure will be performed. In some cases, mild sedation may also be given to help the patient relax.

  2. Incision: A small incision, typically less than one centimeter in size, is made in the skin of the lower back at the site of the affected vertebrae.

  3. Access to the Spinal Canal: Using fluoroscopic guidance (real-time X-ray imaging), a specialized needle is inserted through the incision and guided toward the spinal canal.

  4. Dilation: A series of progressively larger dilating tubes are passed over the needle to gently widen the pathway to the spinal canal. This process creates a small tunnel through the muscle tissue, minimizing damage to surrounding structures.

  5. Removal of Tissue and Bone: Once the tunnel is created, specialized instruments are inserted through it to remove excess bone, ligament, and other tissue that may be compressing the spinal nerves. This step is crucial for decompressing the spinal canal and relieving pressure on the nerves.

  6. Closure: After the necessary decompression is achieved, the instruments are removed, and the small incision is typically closed with a stitch or two. Because of the minimal tissue disruption, sutures may not always be required, and the incision may be covered with a small bandage.

  7. Recovery: After the procedure, patients are usually monitored for a short time in a recovery area to ensure there are no immediate complications from the surgery. Most patients can return home the same day, although some may need to stay overnight for observation, depending on their overall health and the recommendation of their healthcare provider.

It’s essential to note that while the above steps provide a general overview, the specifics of the mild procedure may vary slightly depending on the patient’s unique anatomy and the surgeon’s preferred techniques. Additionally, thorough preoperative evaluation and postoperative care are essential for a successful outcome.

While the mild procedure is considered minimally invasive and generally safe, like any medical procedure, it carries some risks. Here are some potential risks and complications associated with the mild procedure:

  1. Infection: Any surgical procedure carries a risk of infection at the incision site or within the surgical area. Proper sterilization techniques and antibiotic prophylaxis help minimize this risk.

  2. Bleeding: Although the mild procedure involves minimal tissue disruption, there is still a risk of bleeding during or after the surgery. In most cases, any bleeding is minimal and can be controlled during the procedure.

  3. Nerve Injury: While the goal of the mild procedure is to relieve pressure on the spinal nerves, there is a small risk of inadvertently injuring nearby nerves during the surgery. This can lead to symptoms such as pain, numbness, or weakness.

  4. Dural Tear: The dura mater, a protective layer surrounding the spinal cord and nerves, can be accidentally punctured or torn during the procedure. This complication may result in cerebrospinal fluid leakage, which can lead to headaches and require additional treatment.

  5. Failure to Relieve Symptoms: Although the mild procedure is effective for many patients, there is no guarantee that it will completely alleviate symptoms of lumbar spinal stenosis. Some patients may experience partial relief or may require additional treatments.

  6. Allergic Reaction: While rare, some patients may experience an allergic reaction to anesthesia, contrast agents used during imaging, or other medications used during the procedure.

  7. Blood Clots: Prolonged immobility during and after the procedure can increase the risk of developing blood clots in the legs (deep vein thrombosis) or lungs (pulmonary embolism).

  8. Persistent Pain or New Symptoms: Some patients may experience persistent or new symptoms after the procedure, such as ongoing back pain, nerve irritation, or weakness. These issues may require further evaluation and treatment.

It’s essential for patients to discuss these potential risks and complications with their healthcare provider before undergoing the mild procedure. Additionally, patients should follow all preoperative and postoperative instructions to minimize the likelihood of complications and promote a successful recovery.


If the mild procedure does not effectively relieve the symptoms of lumbar spinal stenosis or if the symptoms persist or worsen after the procedure, several options may be considered:

  1. Conservative Management: Before exploring further invasive interventions, conservative treatments may be attempted or continued. These can include physical therapy, pain management techniques, chiropractic care, and medications to manage pain and inflammation.

  2. Repeat Procedure: In some cases, a repeat mild procedure may be considered, especially if the initial procedure did not adequately address all contributing factors or if there has been a gradual recurrence of symptoms over time.

  3. Alternative Minimally Invasive Procedures: If the mild procedure was not successful, other minimally invasive surgical options may be explored. These could include techniques such as percutaneous decompression, endoscopic spinal surgery, or laser spine surgery. These procedures may target different aspects of the spinal anatomy or utilize alternative approaches to decompress the spinal canal and relieve nerve compression.

  4. Traditional Open Surgery: If minimally invasive techniques are not effective, traditional open surgery may be considered as a last resort. Procedures such as laminectomy or laminotomy involve more extensive removal of bone and tissue to decompress the spinal canal and relieve pressure on the nerves. While open surgery may be effective for some patients, it typically involves a longer recovery time and higher risk of complications compared to minimally invasive approaches.

  5. Consultation with Specialists: If the mild procedure is not successful, patients may benefit from consultation with specialists such as neurosurgeons, orthopedic surgeons, or pain management physicians to explore alternative treatment options and develop a comprehensive care plan.

It’s important for patients to communicate openly with their healthcare providers about their symptoms, treatment preferences, and goals. Together, they can assess the effectiveness of the mild procedure and determine the most appropriate next steps to address the underlying cause of the symptoms and improve quality of life.

After undergoing the mild procedure, patients are typically advised to follow specific guidelines to promote healing and minimize the risk of complications. While individual recommendations may vary based on the patient’s unique circumstances and the surgeon’s instructions, here are some general precautions and activities that patients may be advised to avoid:

  1. Strenuous Activities: Patients are often instructed to avoid heavy lifting, strenuous exercise, and activities that involve bending, twisting, or straining the back for a certain period following the procedure. This helps prevent excessive stress on the spine and allows the surgical site to heal properly.

  2. Driving: Patients may be advised not to drive for a certain period after the procedure, especially if they are still experiencing pain, discomfort, or reduced mobility. Driving restrictions may vary depending on factors such as the patient’s overall condition, the type of anesthesia used during the procedure, and any medication they may be taking.

  3. Prolonged Sitting or Standing: Sitting or standing for extended periods may increase pressure on the spine and slow down the healing process. Patients may be encouraged to alternate between sitting, standing, and walking throughout the day and to take frequent breaks to avoid prolonged periods of immobility.

  4. Heavy Lifting or Straining: Patients should avoid lifting heavy objects or engaging in activities that require significant physical exertion, as this can strain the muscles and tissues around the surgical site and increase the risk of complications.

  5. Smoking and Alcohol Consumption: Smoking and excessive alcohol consumption can impair the body’s ability to heal and increase the risk of complications after surgery. Patients may be advised to refrain from smoking and limit alcohol intake during the recovery period.

  6. Skipping Follow-up Appointments: Follow-up appointments with the surgeon are essential for monitoring the progress of recovery, addressing any concerns or complications, and adjusting the treatment plan as needed. Patients should attend all scheduled follow-up appointments and notify their surgeon if they experience any unusual symptoms or issues.

  7. Ignoring Pain or Discomfort: While some discomfort is normal after surgery, patients should not ignore severe or worsening pain, swelling, numbness, or other concerning symptoms. It’s essential to promptly report any unusual symptoms to the healthcare provider for evaluation and appropriate management.

Overall, patients should carefully follow their surgeon’s postoperative instructions and guidelines to optimize their recovery and achieve the best possible outcomes after the mild procedure.
