Orthotics and prosthetics are essential components of orthopaedic rehabilitation, with orthoses used to support, align, protect or correct existing body segments and prostheses used to replace missing limbs. Orthotic devices such as AFOs, KAFOs, spinal braces and upper-limb splints work through biomechanical principles including three-point pressure, pressure distribution and lever-arm control. Prosthetic rehabilitation depends on an appropriately prepared residual limb, comfortable socket, effective suspension, correct alignment and selection of suitable components such as prosthetic feet and knee joints. Modern technologies include dynamic-response feet, microprocessor-controlled knees, myoelectric upper-limb prostheses and osseointegrated systems. Successful treatment requires individualised prescription, prevention of contractures and skin complications, appropriate gait and functional training, and close multidisciplinary rehabilitation.
