What is a spinal discectomy?

‍

A spinal discectomy is a surgical procedure performed to treat herniated or bulging discs in the spine. The procedure aims to relieve pressure on the spinal nerves or the spinal cord caused by the damaged or protruding disc.

‍

The intervertebral discs are cushion-like structures located between the vertebrae of the spine. They act as shock absorbers and allow for flexibility and movement of the spine. Sometimes, due to age, injury, or degenerative changes, a disc can become damaged and bulge out of its normal position, leading to a herniated disc. This can result in compression of nearby spinal nerves or the spinal cord, leading to pain, weakness, numbness, or tingling in the arms or legs, depending on the location of the herniation.

‍

During a spinal discectomy, the surgeon makes a small incision over the affected area of the spine and uses specialized instruments to remove the damaged portion of the disc. This relieves pressure on the affected nerves or spinal cord, alleviating the associated symptoms. The surgery is typically performed using a microscope or an endoscope, allowing for a minimally invasive approach with smaller incisions and reduced damage to surrounding tissues.

‍

In some cases, a discectomy may be combined with a spinal fusion surgery to provide stability to the spine, especially if there is significant disc degeneration or instability.

‍

Spinal discectomy is considered an effective treatment for herniated discs when conservative treatments such as rest, physical therapy, and medications do not provide sufficient relief. However, like any surgical procedure, there are potential risks and complications associated with spinal discectomy, and it should be carefully considered in consultation with a spine specialist or neurosurgeon. The decision to undergo a spinal discectomy is based on the patient's specific condition, medical history, response to conservative treatments, and overall health. Each patient's unique circumstances and individual health factors will influence the suitability and potential benefits of the procedure.

‍

Who can benefit from a spinal discectomy?

‍

A spinal discectomy can benefit individuals who have a herniated or bulging disc in the spine that is causing compression of spinal nerves or the spinal cord, leading to symptoms such as:

‍

1. Radiculopathy: Compression of spinal nerves can cause radiating pain, weakness, numbness, or tingling in the arms or legs, depending on the location of the herniated disc.
2. Sciatica: If the herniated disc is in the lumbar spine (lower back), it can lead to sciatica, a condition characterized by pain, numbness, and weakness that radiates down the buttocks and leg.
3. Cervical radiculopathy: When the herniated disc is in the cervical spine (neck), it can cause symptoms that radiate into the shoulder, arm, and hand.
4. Muscle weakness: Pressure on the nerves can result in muscle weakness in the affected area, leading to difficulty in performing daily activities.
5. Numbness or tingling: Compression of nerves can cause sensations of numbness or tingling in the affected extremities.
6. Loss of bladder or bowel control (rare): In severe cases, a large herniation or disc prolapse can lead to compression of the spinal cord, which may cause a loss of bladder or bowel control. This is a medical emergency and requires immediate attention.

‍

Individuals who have tried conservative treatments such as rest, physical therapy, pain medications, and corticosteroid injections without significant improvement in their symptoms may be considered for a spinal discectomy.

‍

It's important to note that not all cases of back or neck pain are due to herniated discs, and conservative treatments are often the first-line approach. Proper evaluation and diagnosis by a spine specialist or neurosurgeon are crucial to determine if a spinal discectomy is the most appropriate treatment option for an individual's specific case.

‍

The decision to undergo a spinal discectomy should be made in consultation with a qualified medical professional who can thoroughly assess the patient's spine condition, medical history, response to conservative treatments, and overall health to determine if a spinal discectomy is the best course of action. Each patient's unique condition and individual health factors will influence the suitability and potential benefits of the procedure.

After a spinal discectomy: What to expect

‍

After a spinal discectomy, the recovery process is essential to ensure proper healing and successful rehabilitation. Here's what you can generally expect during the post-operative period:

‍

1. Hospital stay: Spinal discectomy is usually performed as an outpatient procedure, meaning you will be able to go home the same day as the surgery. In some cases, a short hospital stay may be required depending on the extent of the procedure and your surgeon's preferences.
2. Pain management: You may experience some pain and discomfort at the surgical site after surgery. Your healthcare team will prescribe pain medications to manage post-operative pain.
3. Restrictions on activities: Your surgeon will provide specific restrictions on activities, which may include avoiding heavy lifting, bending, and twisting during the initial recovery phase.
4. Suture and incision care: You will need to care for the surgical incision and keep it clean and dry as directed by your surgeon to promote proper healing and minimize scarring.
5. Mobility and physical activity: You will be encouraged to start walking and moving around gently in the days following surgery. Gradual mobility and physical activity are essential for preventing complications and promoting healing.
6. Physical therapy: Physical therapy is a crucial part of the recovery process. Your surgeon may recommend physical therapy to help you regain strength, flexibility, and mobility in the spine and surrounding muscles.
7. Timeframe for recovery: The recovery period varies from person to person and depends on the extent of the discectomy and individual healing factors. Most individuals can expect to resume light activities within a few weeks, with a gradual return to normal activities over several weeks to months.
8. Follow-up appointments: You will have regular follow-up appointments with your surgeon to monitor your progress, check the surgical site, and discuss any concerns or questions.
9. Return to work and activities: The timeframe for returning to work and normal activities will depend on the extent of the surgery and the type of work you do. Your surgeon will provide guidance on when you can safely resume these activities.
10. Pain relief and symptom improvement: Over time, you can expect a reduction in pain and improvement in the symptoms caused by the herniated disc as you heal and recover from surgery.

‍

It's essential to follow your surgeon's instructions diligently and attend any scheduled follow-up appointments to ensure a successful recovery. Adhering to post-operative care guidelines and participating in physical therapy exercises will lead to the best possible outcome, allowing you to gradually resume your normal activities with reduced pain and improved spine function. As with any surgery, there are potential risks and complications associated with spinal discectomy, and your surgeon will provide you with specific information about the procedure and its potential outcomes.

How can physical therapy help? 

‍

Physical therapy plays a crucial role in the recovery process after a spinal discectomy. A physical therapist will design a personalized rehabilitation program to promote healing, restore spine strength and flexibility, and guide you back to your normal activities. Here's how physical therapy can help with recovery from a spinal discectomy:

‍

1. Pain Management: Physical therapists use various modalities such as ice, heat, electrical stimulation, and ultrasound to manage post-operative pain, reduce muscle tension and swelling around the surgical site.
2. Bed Mobility Exercises: Part of the initial postoperative rehabilitation program for a patient who had spinal discectomy procedure is bed mobility exercises. The patient must relearn how to perform bed mobility to facilitate trunk and limb control, as they may be wearing a spinal orthotic that prevents normal movement.
3. Mobility and Flexibility Exercises: Early after surgery, physical therapists focus on a gentle range of motion exercises which includes: active range of motion with or without assistance to prevent stiffness and maintain flexibility in the spine as well as the upper and lower extremities. As the patient improves, progressive stretching and joint mobilization are prescribed to increase flexibility and range of motion of the restricted tissues.
4. Stabilization and Strengthening Exercises: As healing progresses, physical therapists initiate stabilization exercises to improve spinal stability. It includes activation of the deep muscles for segmental stability and global (outer core) muscles for general stability. The therapists also prescribe strengthening exercises to improve spinal muscle strength, endurance and performance such as: low to moderate intensity dynamic spinal exercises as well as trunk and extremity strengthening exercises. 
5. Kinesthetic/Proprioception Training:  One of the fundamental interventions after spinal discectomy procedure is to develop patient awareness of safe spinal positions and movement as well as the effects of different positions (e.g. lying, sitting and standing) on the spine. Awareness and control of spinal posture and movement are progressed and incorporated into all the exercises of the patient. 
6. Body Mechanics Education: Physical therapists offer guidance on proper body mechanics during movements, such as lifting, pushing, pulling and other activities to avoid putting excess stress on the spine.
7. Gradual Return to Activities: Your physical therapist will guide you in a step-by-step approach to resume daily activities and functional tasks, ensuring your safety and allowing adequate time for healing.
8. Aerobic Exercises: Aerobic conditioning exercises are initiated as soon as the patient tolerates repetitive activity without pain and discomfort. Emphasis is placed on using safe spinal postures while exercising. Aerobic activity increases the patient’s feeling of well-being and improves cardiovascular and pulmonary fitness.
9. Patient Education: Physical therapists educate patients about spinal discectomy procedure, its indications and benefits as well as the role and importance of postoperative rehabilitation programs. They also instruct patients on any restrictions as detailed by the surgeon and teach techniques and strategies on maintaining a healthy spine.
10. Gait Training: If your spinal discectomy affected your walking pattern or balance, your physical therapist will work on gait training to help you walk with proper mechanics and appropriate walking pattern to unload the stress on the surgical area .
11. Functional Training: A final component of an individualized rehabilitation program involves practicing activities that simulate the physical demands of a patient’s work or desired recreational or sport activity. Simulated activities and drills enable a patient to practice under supervised conditions to receive feedback on correct mechanics. 
12. Scar Tissue Management: Physical therapists may perform scar tissue mobilization techniques after the incision site is healed, to improve connective tissue mobility as well as to promote tissue healing and reduce scar adhesions around the surgical site.
13. Home Exercise Program: Physical therapists provide a specialized home exercise program for each patient and teach how to safely and effectively incorporate it into their daily routine to reinforce the interventions and promote optimal recovery.
14. Progress Monitoring: Physical therapists continually monitor your progress and adjust the treatment plan as needed to ensure a successful recovery.

‍

Physical therapy is essential to optimize your recovery after a spinal discectomy. The therapist's expertise and guidance are instrumental in promoting healing, preventing complications, and helping you regain spine strength, flexibility, and mobility. Consistent participation in physical therapy exercises and adherence to your therapist's recommendations will lead to the best possible outcome, allowing you to gradually resume your normal activities with reduced pain and improved spine function. It's important to communicate openly with your physical therapist and follow the prescribed exercises and guidelines to achieve the most favorable results from your rehabilitation program.
