Perineural Injection Therapy (PIT) is a proven safe, effective treatment for patients who may not be candidates for joint replacement surgery or biologic options such as stem cell injections or PRP. Perineural injection therapy treats inflamed and injured nerves. Chronic nerve pain is often due to trauma, arthritis, sports, overuse, occupational, and surgical injuries.
Any sensation that is perceived by the brain is transmitted to the brain via the sensory nervous system. This is true for sensations like pain, temperature, vibration, or pressure. For example, when a nerve is stimulated by pain, the individual nerve cells generate an electrical current that is carried by the nerve to the spinal cord and then to the brain.
How does Perineural Injection Works?
It works by stimulating the body’s natural healing mechanisms to lay down new tissue in the weakened area. This is done by a very directed injection to the injury site, “tricking” the body to repair again. The mild inflammatory response which is created by the injection encourages growth of new, normal ligament or tendon fibers, resulting in a tightening of the weakened structure. Additional treatments repeat this process, allowing a gradual buildup of tissue to restore the original strength to the area.
What Areas of the Body Can be Treated?
Areas/problems treated include: Low back or mid-back pain including degenerative disc disease and sacro-iliac joint instability/dysfunction, neck pain, knee pain, knee meniscal tears, wrist or hand pain, osteoarthritis, shoulder pain including rotator cuff tears, elbow pain including golfers or tennis elbow, foot pain including plantar fasciitis, ankle pain or instability, hypermobility, osteitis pubis, IT band syndrome, piriformis syndrome, temporomandibular joint syndrome (TMJ), or other musculoskeletal pain or injury. Some areas or problems can be more challenging than others, and it is therefore important to be evaluated by a physician trained and experienced in this procedure so that an accurate assessment and treatment plan can be given.
What’s the rate of success?
The anticipated rate of success depends on a number of variables, including the patient’s history and ability to heal, and the type of solution used. In patients with low back pain, studies have shown 85% to 95% of patients experience improvement with Perineural Injection (compared to studies showing a 52% improvement with back surgery). Many studies done over the years show a high success rate when Perineural Injections are used for various ligament, tendon or joint pain/injuries.
