Cause, clinical and ultrasound findings
The technique is used to treat tendinopathy, most often the rotator cuff, the epicondylitis insertions at the elbow and the plantar fascia. Coblation has been used for the Achilles and patellar tendon; however, tendon rupture is a substantial risk. The technique is regarded as an alternative to surgical debridement. It is intended to trigger a ‘controlled inflammatory process to initiate healing’. The probe delivers electrically conductive fluid (saline) to the tip of the catheter, and an applied current creates a charge layer of particles called a plasma layer. This breaks molecular bonds within the cells, effectively vapourising tissue in a very localised area.
Technique
While the device is used by some surgeons with an open incision under direct visual guidance, the wand may also be introduced into the affected area through a cannula under ultrasound guidance.
