[Management of upper limb deformities. Treatment concepts through the years]

The provision of aids and prostheses for patients with upper limb deficiencies has to be based on comprehensive knowledge in the field of orthopaedic technology. Taking into account the patient's complete background, evaluation of the possible functional benefit is mandatory in order to achieve good acceptance of a prosthesis in the long term. The extent of extremity "loss" and the remaining function of the deficient limb have an impact on the success of prosthetic fitting. Furthermore, there is a trend towards myoelectric prostheses, which seem to improve prosthetic acceptance. Bilateral congenital deficiency of the upper limbs cannot be equated with amputations. Most people affected do not push for a prosthesis, but should be provided with one, if the need arises. Decades of overuse of the deficient limbs often take their toll in terms of decreasing function as degenerative changes occur. As a consequence, artificial upper limbs may be obligatory to prevent loss of independence.
