Abstract

See full text

A method for modifying a ligament connection between two bones by applying radio frequency energy to a portion of a ligament in a patient that functions to maintain two or more bones in a standard configuration in a species to which the patient belongs, but which are in a relationship to each other that is not medically acceptable in the patient, for a time sufficient to induce thermal shrinkage of the portion of the ligament. The method is particularly useful for skeletal-shift disorders by applying radio frequency energy to one ligament of a set of ligaments of a patient that function to align two or more bones in a standard configuration in a species to which the patient belongs but which are causing a skeletal shift in the patient because of an imbalance of ligament-induced forces in the patient for a time sufficient to induce thermal shrinkage of the portion of the ligament, thereby alleviating the skeletal shift. Patellar shift and curvature of the spine are two examples of such disorders.
