Electrostimulation: uses and applications for periprosthetic capsular contracture: experimental model
Background:
Studies have documented an increase in collagen production and acceleration of the scarring process when galvanic electrostimulation of less than 300 mV is used, but the effects of electrostimulation with characteristics different from those usually studied are unknown.
Methods:
Electrostimulators were designed and manufactured specifically for the study. A total of 40 rats were divided into 10 groups, with 4 randomly selected rats in each group. Five groups received smooth implants, and the remaining five groups received textured implants. The first group was designated as the control group, and the remaining four groups received electrostimulation in differing amounts from the 3rd to the 15th postoperative day.
Results:
The type of implant used was not a determining factor in the degree of capsular contracture encountered. In the groups that received less than 300 mV, showed greater capsule thickness than the control group. The group that received 600 mV, had a thinner periprosthetic capsule than the control group and all the other groups. All the results were statistically significant.
Conclusions:
Electrostimulation using direct galvanic current with reversal of polarity on postoperative day 3 at intensities of 600 mV inhibits the process of periprosthetic capsular formation in rats.
