Thirty-five percent of orthopaedic surgeons designate themselves as general orthopaedic surgeons. Fifty percent of an orthopaedist's practice is devoted to non-surgical or medical management of injuries or disease, and 50% to surgical management. A general orthopaedist works closely with other healthcare professionals, such as physical and occupational therapists, orthotists, and prosthetists, as well as orthopaedic surgeons with sub-specialty training. Seventy percent of general orthopaedic surgeons also have a sub-specialty interest. A general orthopaedic surgeon has completed 14 years of training plus passing the Orthopaedic Board Examination to be certified as an orthopaedic surgeon.
