Over the past 75 years, the profession has evolved from one of artisanal work involving carving wood and bending metal, to a science involving microprocessors, composites, and computer-aided design and manufacturing. Although materials and processes have changed, orthotic design remains largely custom or customized for the individual patient. The orthotist must consider the pertinent patient history, underlying pathologies, the biomechanical system and the impact of the orthosis on this system, sensation, skin integrity, the prognosis, as well as patient preferences and desired goals when determining optimal orthotic care. This is done in coordination with family, physicians, therapists, and other members of the health care team. This chapter will review basic orthotic designs and management principles for the upper limb, lower limb, and spine.
