A Physician Assistant (PA) is a medical professional who practices medicine under the direction of a physician. Both the physician and the PA share responsibility for patient care. Examining patients, diagnosing illness, recording a medical history, developing and carrying out a treatment plan, assisting in surgery, prescribing medications, performing minor procedures and counseling with patients are duties that fall under the scope of a PA. A PA is not licensed to perform surgery, but at Southern Oregon Orthopedics, each of our surgeons partners with a PA to make sure that patients get prompt, thorough care. Our PAs are qualified to meet with patients, treat many conditions and assess whether or not patients should be further assessed by a surgeon.
