A diagnostician is a physician who possesses expert skills at figuring out the exact anatomical cause of each patient’s complaints. The diagnostician will use their experience and knowledge to carefully ask specific questions that will be invaluable in determining a diagnosis. The physical exam will carefully assess each and every individual anatomical structure in the area of interest to better determine which of these structures are causing the trouble. Diagnostic tests, including X-ray, EMG, MRI, ultrasound and other studies will be implemented sparingly and only when necessary to help arrive at the precise diagnosis.  Only when this diagnosis is determined can proper treatment be prescribed. Dr. Portner and his staff pride themselves on the reputation they’ve earned in the Honolulu medical community as excellent diagnosticians. The team is regularly sent the most difficult and puzzling cases to help the referring physician sort out the cause, or causes, of enigmatic orthopedic pains.
