Percutaneous Discectomy, also known as Dekompressor (Stryker) is a non-percutaneous-discectomysurgical effective treatment for back and neck pain associated with herniated disc disease. The pain relief associated with this therapy is due to taking the pressure off of the spinal discs and facet joints. This reduces the pressure exerted onto the spinal cord and nerve roots, which is causing the pain (Boswell 2007). Separating each individual spinal vertebrae are discs that act as cushions to minimize the impact that the spinal column receives. Since the discs are designed to be soft and provide support, they have a tendency to herniate (bulge) backwards through the outer disc segment and ligaments. These bulging discs can cause irritation to the adjacent nerves. Disc disease is one of the most common causes of chronic neck and back pain and accounts for approximately 10% of all lower back pain complaints. Disc disease may be acute, it may be herniation resulting from trauma, or more commonly, from chronic disease. Degenerative disc disease is a process, which is due to a thinning and degeneration of the discs over time. Commonly seen, neck and back pain may go into painless remission with periods of decreased or absent symptoms, however, the pain often returns causing a chronic pain syndrome. If your pain has lasted longer than four weeks or is severe in nature you should see a pain specialist about treatment options. Ongoing research has hinted that early intervention decreases the incidence of developing chronic pain. Decompression therapy is often considered when the pain has not improved after a month and is radiating, resulting from irritation of the nerve roots.


Percutaneous Discectomy uses a single-use probe called the “Stryker Dekompressor,” which is placed using X-Ray guidance. You will be pre-treated with a sedative that will help you to relax, but you will remain awake for the procedure. Before the treatment begins, you will be comfortably positioned on your stomach, with your knees supported on the table. Your physician will inject a local anesthetic with a small needle to numb the area. Once the area is numb, a larger needle is placed into the affected disc with X-Ray guidance. The probe is placed through this needle and the procedure is initiated. You may feel pressure during this part of the procedure, but should not experience pain. The Dekompressor uses a pump method to remove excessive disc material from bulging or contained herniated discs, thus reducing pressure in the disc and providing pain relief.


A discectomy using the Dekompressor is a lower-risk treatment option for neck and back pain. The procedure may decrease pain, increase mobility, and eliminate the need for traditional surgery. This treatment is designed to correct the underlying problem, not just relieve the symptoms. The procedure is a minimally invasive procedure that causes much less scarring and fibrosis that is commonly associated with other interventions. A study reported in 2007  stated that “discectomy is minimally invasive, safe and effective for treating disc herniations and that 89% of patients treated by this method stated they achieved successful outcomes from the therapy“ (Tzaan 2007).


As with all medications and surgical procedures, there is always a risk of complications. With lower risks than traditional back surgery, discectomy is considered an appropriate treatment for many patients who suffer from back pain (Boswell 2007). The most common complaint is mild back pain at the injection site shortly after the procedure. Other more serious and far less common complications include spinal cord compression, excessive intracranial pressure, bleeding, hematoma, or infection. These particular risks are decreased by the use of X-Ray and sterile technique.


The American Society of Interventional Pain Physicians developed a large evidence-based practice guideline for the management of chronic spinal pain with interventional techniques. The 2007 article stated that for percutaneous discectomy using the Dekompressor resulted in greater than 70% improvement in pain in 79% of patients undergoing the treatment for postero-lateral disc herniations. (Boswell 2007). The reduction in pain allows patients to experience enough relief to become active again. Often patients regain the ability to resume their normal daily activities.
