Technical orthopaedics is part of the examination taken by orthopaedic physicians and it is an important aspect of the practical work performed by orthopaedic practitioners. Technical orthopaedic aids (e.g. crutches, bandages, splints, corsets, stays, orthopaedic shoes, shoe insoles etc.) are an integrative part of therapy for deformities and dysfunctions of the locomotor system. They can supplement orthopaedic treatment, but are also often used on their own.  Orthopaedic aids frequently replace plaster casts thus facilitating the early mobilisation of patients following injuries or operations.  The orthopaedic practitioner and the orthopaedic technician work closely together, both have specialist qualifications in technical orthopaedics and are experts in indication, economical prescription methods and fitting the appropriate aid.
