Microdiscectomy in Los Angeles

A microdiscectomy is a minimally invasive spine surgery used to relieve pressure on a spinal nerve. During the procedure, the surgeon removes the small portion of a herniated or damaged disc that is compressing the affected nerve rather than removing the entire disc.

The surgery is performed through a small incision using magnification and specialized instruments. Compared with a traditional open discectomy, this approach generally requires less disruption of the surrounding muscles and soft tissue.

Microdiscectomy is most commonly performed in the lumbar spine to address sciatica and other symptoms caused by a herniated disc. Similar microsurgical techniques may also be used for carefully selected cervical and thoracic disc herniations.

The recommended surgical approach depends on where the damaged disc is located, which nerves are affected, the direction of the herniation, and the patient’s overall spinal anatomy.

Cervical Microdiscectomy

A cervical microdiscectomy treats nerve compression in the neck. A herniated cervical disc may press against a nerve root and cause pain that travels into the shoulder, arm, or hand. Patients may also experience numbness, tingling, or muscle weakness.

In selected cases, a posterior cervical microdiscectomy may be performed through a small incision in the back of the neck. The surgeon carefully reaches the affected nerve and removes the disc fragment causing compression. This approach is not suitable for every cervical disc herniation, and some patients may require a different procedure based on the location of the disc and the presence of spinal cord compression.

Thoracic Microdiscectomy

A thoracic microdiscectomy addresses a herniated disc in the middle portion of the spine. Thoracic disc herniations are less common than cervical or lumbar herniations, and their treatment can be more complex because of the nearby spinal cord and rib cage.

Symptoms may include pain around the chest or ribs, numbness, balance difficulties, leg weakness, or changes in walking. The surgical approach is selected according to the size and position of the herniation and whether it is compressing a nerve root or the spinal cord.

Because thoracic disc surgery is relatively uncommon, patients require a detailed evaluation to determine whether a microsurgical discectomy or another approach is appropriate.

Lumbar Microdiscectomy

Lumbar microdiscectomy is the most common form of microdiscectomy. It treats a herniated disc in the lower back that is irritating or compressing a spinal nerve.

Compression of a lumbar nerve can cause sciatica, including sharp or burning pain that travels from the lower back or buttock into the thigh, calf, or foot. Other symptoms may include numbness, tingling, or weakness in the affected leg.

During surgery, the compressed nerve is identified and protected while the displaced disc fragment is removed. The goal is to relieve nerve pressure while preserving the remaining disc and maintaining spinal stability.

Microdiscectomy may be recommended for conditions involving focal disc material that is placing pressure on a nerve, including:

• Cervical, thoracic, or lumbar disc herniation
• Lumbar radiculopathy or sciatica
• Cervical radiculopathy
• Nerve-root compression
• Pain that radiates into an arm or leg
• Numbness or tingling caused by nerve compression
• Muscle weakness associated with a compressed nerve
• Recurrent disc herniation in selected patients

Microdiscectomy is not intended to treat every cause of neck or back pain. It is generally most effective when imaging findings correspond with a patient’s nerve-related symptoms.

Many herniated discs improve without surgery. Initial treatment may include activity modification, medication, physical therapy, or spinal injections. Microdiscectomy may be considered when these treatments do not provide adequate relief or when nerve-related symptoms significantly interfere with mobility, sleep, work, or daily activities.

Potential candidates may have:

• Persistent radiating arm or leg pain
• A confirmed disc herniation on MRI or other imaging
• Symptoms that match the location of the compressed nerve
• Numbness, tingling, or weakness caused by nerve compression
• Difficulty standing, walking, working, or performing normal activities
• Symptoms that have not improved with appropriate nonsurgical treatment
• Progressive neurological changes requiring more urgent evaluation

A surgical recommendation is based on more than an imaging result. The surgeon will review the patient’s symptoms, physical examination, medical history, previous treatments, and diagnostic imaging before determining whether microdiscectomy is appropriate.

New loss of bladder or bowel control, numbness around the groin or inner thighs, or rapidly worsening weakness requires immediate medical evaluation because these symptoms may indicate severe nerve compression.

Before surgery, patients undergo a clinical examination and imaging review. Additional testing may be needed to evaluate general health and prepare for anesthesia. Patients will also receive instructions regarding medication, eating, drinking, transportation, and arrival time.

Microdiscectomy is usually performed under general anesthesia. The surgeon makes a small incision over the affected spinal level and gently moves or separates the surrounding muscle to access the spine.

Using a surgical microscope or another form of magnification, the surgeon identifies the compressed nerve and removes the displaced disc fragment. In some cases, a small amount of bone or ligament may also be removed to safely reach the nerve and create sufficient space.

The incision is then closed and covered with a dressing. Many procedures are completed on an outpatient basis, although the need for an overnight stay depends on the location and complexity of the surgery, the patient’s health, and their response after anesthesia.

Patients are commonly encouraged to begin walking soon after surgery. Some soreness, stiffness, or discomfort around the incision is expected during the initial recovery period.

Radiating nerve pain may improve quickly, but numbness, tingling, or weakness can take longer to recover. Nerves heal gradually, and the amount of recovery depends partly on how severely and how long the nerve was compressed.

Postoperative instructions may include:

• Taking short, frequent walks
• Keeping the incision clean and dry
• Avoiding heavy lifting, forceful twisting, and repeated bending
• Gradually increasing activity as directed
• Using prescribed or approved pain medication
• Attending postoperative follow-up visits
• Beginning physical therapy when recommended

Return-to-work timing varies. A patient with a sedentary position may resume work sooner than someone whose job involves lifting, driving, climbing, or strenuous physical activity. Patients should follow their surgeon’s individual restrictions rather than relying on a fixed recovery timeline.

Physical therapy may be recommended to improve strength, flexibility, posture, and movement mechanics. Rehabilitation can also help patients return safely to work, exercise, and recreational activities.

Microdiscectomy is generally considered a focused, minimally invasive procedure, but every surgery carries risks. Potential complications include:

• Infection
• Bleeding or a collection of blood near the surgical site
• Reaction to anesthesia
• Injury to a spinal nerve
• Dural tear and leakage of spinal fluid
• Persistent or recurrent symptoms
• Recurrent disc herniation
• Blood clots
• Spinal instability
• The need for additional treatment or surgery

Serious complications are uncommon, but individual risk depends on the patient’s health, spinal condition, surgical level, and procedure performed.

Successful recovery may be indicated by reduced radiating pain, improved walking or sitting tolerance, better sleep, increased strength, and a gradual return to normal activities. Leg or arm pain caused by direct nerve compression often improves more predictably than longstanding numbness, weakness, or general back pain.

Patients should contact their surgical team for worsening pain, increasing weakness or numbness, fever, excessive wound drainage, severe headaches, difficulty urinating, loss of bladder or bowel control, chest pain, or shortness of breath.
