Abstract
The present invention is directed to a method of treating bone length discrepancies and angular deformities in a patient in need thereof, where the method involves radiofrequency ablation epiphysiodesis of a physeal plate. Specifically, the method treats long bone discrepancies with a minimally invasive procedure. The present invention is also directed to a method of inhibiting bone growth, where the method involves exposing a physeal growth plate to radiofrequency ablation epiphysiodesis.
Claims16
A method of treating bone length discrepancy in a patient in need of such treatment, which comprises
- (a) identifying a target bone growth plate site;
- (b) making at least one percutaneous incision at the target site;
- (c) inserting a guide wire into the incision site transversely into physeal cartilage at the target site to create a channel;
- (d) inserting a radiofrequency electrode probe into the channel, wherein the probe is connected to a radiofrequency generator;
- (e) heating the probe to ablate the target site for a set duration of time;
- (f) removing the probe;
- and
- (g) surgically closing the incision;
- wherein a physeal growth plate on a bone in need of such treatment is destroyed using radiofrequency ablation epiphysiodesis.
