Use of capacitive coupled electric fields in stress fractures in athletes

Abstract

The authors report the results of an open study on the treatment of stress fracture in athletes by capacitive coupling, a bone healing stimulation method promoting bone formation by application of alternating current in the form of a sinusoidal wave. Twenty-five lower-limb (navicular, 2nd and 5th metatarsal, tibia, fibula, and talus) stress fractures in 21 athletes (mean age, 21.8 years old) were treated. The mean stimulation time was 52 days (navicular fractures, 60 days). Twenty-two fractures were healed, 1 was not healed, and 2 were improved. This preliminary report shows that capacitive coupling can be used safely in the treatment of these stress fractures.
