Thermal capsulorrhaphy for acute or chronic shoulder instability

During the past two decades, arthroscopic procedures have been replacing traditional, more invasive orthopedic surgical procedures. As technology becomes more advanced, the opportunity to provide a greater number of minimally invasive surgical interventions continues to improve. Thermal modification of joint capsule and ligamentus tissues, a recent introduction to medical science, has been investigated extensively during the past six years. Arthroscopic thermal capsulorrhaphy is one such procedure, and it is performed on individuals with a history of joint instability. These patients now can be treated surgically without large incisions and significant shoulder joint trauma. The thermal unit in both monopolar and bipolar models has similar properties to those of the basic electrosurgical unit. Relatively low-temperature heat is directed to the supportive structures of the shoulder joint causing the tissues to expand. This tightens a previously stretched and attenuated shoulder capsule.
