Physician assistants are health care professionals licensed to practice medicine with physician supervision and are qualified to conduct physical exams, diagnose and treat illnesses, order and interpret tests, counsel on preventive health care and education, prepare alternate care options, assist in surgery, perform injections and prescribe medications. Within the physician-PA relationship, physician assistants exercise autonomy in medical decision making and provide a broad range of diagnostic and therapeutic services. Physician assistants increase access to health care and are part of a team approach at Countryside Orthopaedics to provide prompt and effective patient treatment.
All of our Physician Assistants perform most in-office procedures including fracture reductions, joint aspiration/injections and casting/splinting.
