A Closer Look At Injection Therapy For Athletes

   “Biopuncture” is another simple needling injection technique. With this technique, the physician raises small wheals in a pattern all around the injured tissue. It is similar to “ringing the dragon,” an acupuncture technique that some physicians use. Raising small wheals or just depositing the medication in individual or specific acupressure or acupuncture points will also work well.

   Percutaneous alcohol nerve sclerosing injection. Also known as alcohol sclerosing injection, this is another injection therapy that podiatric physicians may be under-using. It is an excellent injection therapy that one can use in lieu of surgical intervention, especially for athletes.

   Physicians typically use percutaneous alcohol nerve sclerosing injection for web space neuromas. Hughes and colleagues in 2007 followed 101 patients in a study on alcohol injections for Morton’s neuromas.2 The author related that alcohol injections had a very high success rate in eradicating interdigital web space neurtic pain. Some other studies have shown upwards of 90 percent success rate.3 In the podiatric world, the nerve injection technique can be credited to Marvin D. Steinberg, DPM, and later Max Weisfeld, DPM, and G. Dock Dockery, DPM.4-6

   In theory, the 4% Dehydrated Alcohol Injection (Akorn Pharmaceuticals) produces injury to tissue cells by Wallerian degeneration, dehydration and precipitation of protoplasm, thus casing nerve degeneration. Clinicians would typically perform the injections weekly and approximately three to seven injections may be needed. With each injection, the symptoms diminish.

   Akorn Pharmaceuticals notes that “the injection of alcohol used for therapeutic neurolysis involves amounts too small to produce significant systemic effects of ethyl alcohol.”7 Furthermore, the company states that “Ninety to 98 percent of the product that enters the body is completely oxidized.” The complications are minimal or even rare, but some post-injection neuritis or lymphatic reactions can occur. I have only observed the post-injection neuritis a few times.

In Conclusion

Having a variety of injection techniques in our toolbox is essential for the podiatric physician as we traditionally use many conservative treatments even in the busiest surgical practices. Improving conservative options for any practice improves patient satisfaction, especially when surgery is not an option. This can even be helpful for improving practice revenue when reduced surgical reimbursements are the norm. Most injections have rare or minimal complications, and almost any patient population can benefit.

   When treating chronic conditions, it is imperative for physicians to control any abnormal edema with formal compression products, offload the tissues when appropriate, evaluate for any shoe gear issues and help realign any abnormal foot mechanics with custom orthoses. Any and all of the aforementioned injection protocols will work to their fullest when clinicians address all of these other aspects of patient care as well.

   Additionally, relative rest is important for athletes as continued sport or other aggravating activity will most likely interrupt the proper healing cascade as I mentioned above.
