A recent groundbreaking study concluded that plantar fasciitis treatment combining ultrasound with steroid injections was 95% effective.
Plantar fasciitis is a foot problem affecting the plantar fascia, a connective tissue in the heel. This condition is treatable, but in many cases can take up to a year to be effective.
Luca M. Sconfienza, M.D., from the University of Genoa in Italy, conducted the study. The new treatment involves an ultrasound-guided technique with a steroid injection to the plantar fascia. It is a one-time outpatient procedure involving a small amount of anesthesia. This technique, known as dry-needling, causes small amounts of bleeding that aid in healing the fascia.
It was discovered that 42 of the 44 patients involved in the study had their symptoms disappear entirely within three weeks. “This therapy is quicker, easier, less painful, and less expensive than shockwave therapy,” Dr. Sconfienza stated. “In cases of mild plantar fasciitis, patients should first try non-invasive solutions before any other treatments. But when pain becomes annoying and affects the activities of daily living, dry-needling with steroid injection is a viable option," she added.
Conventional treatment options include certain exercises, rest, arch supports, and night splints. If these options prove to be ineffective, many patients undergo shockwave therapy. In shockwave therapy, sound waves are directed to the area where pain is experienced. This therapy can be effective but also painful, and calls for several sessions. Shockwave therapy is not guaranteed to alleviate pain caused by plantar fasciitis.
Tarsal tunnel syndrome is a condition in which there is a compression of the posterior tibial nerve. The posterior tibial nerve runs along the inside of the ankle into the foot. Tarsal tunnel syndrome is named for the tarsal tunnel, which is a thin space along the inside of the ankle beside the ankle bones. This space contains various nerves, arteries, and tendons, and includes the posterior tibial nerve. The tibial nerve is the peripheral nerve in the leg responsible for sensation and movement of the foot and calf muscles. In tarsal tunnel syndrome the tibial nerve is compressed, causing tingling or burning, numbness, and pain.
Common causes of tarsal tunnel syndrome involve pressure or an injury. Injuries that produce inflammation and swelling in or around the tunnel may place pressure on the posterior tibial nerve. Direct pressure on the tibial nerve for an extended period of time, sometimes caused by other body structures close by or trauma to the tibial nerve, can result in tarsal tunnel syndrome. Diseases that damage nerves, such as diabetes or arthritis, may cause tarsal tunnel syndrome. Those with flat feet are at risk for developing the condition, as the extra pressure and strain placed on the foot may compress the posterior tibial nerve.
Feeling different sensations in the foot at different times is a common symptom of tarsal tunnel syndrome. An afflicted person may experience pain, tingling, burning or other unusual sensations in the foot of the affected leg. Symptoms are primarily felt on bottom of the foot and/or the inside of the ankle. Symptoms can appear suddenly and may occur due to overuse of the foot.
To diagnose tarsal tunnel syndrome, your podiatrist may examine the foot and tap the posterior tibial nerve to see if symptoms surface. He or she may also order an MRI to determine if a mass is present.
Treating tarsal tunnel syndrome will depend on the decision of your podiatrist. Multiple options are available, however, and can include rest, ice, immobilization, oral medications such as anti-inflammatory drugs (NSAIDS), physical therapy, injection therapy, orthotics, supportive shoes, braces, and surgery.
