For determination of MdE-value clinical examination is required with determination of movement measures as well as motoric and neurological failures. A evaluation of specific professional conditions is not interesting [4, 5, 8].

Analogous to assessment of the results of a proximal humerus fracture in context of determination of the degree of handicap according to the seriously handicapped person law it is just usual to fix function deficits. Handicap is a condition against the rules differing from the norm which lasts more than 6 months and exceeds age corresponding measure. Therefore the anyway existing age corresponding changes cannot be evaluated in the form of arthrotic and degenerative changes in the shoulder [1, 2].

The tables to the assessment of the degree of handicap therefore contain an estimation space in which the function deficits are contained as a rule [1] (Table 22.2).

Abolition of the forearm trick movability isolated in an unfavorable position

20

Abolition of the forearm trick movability isolated in an extreme supination

The sensibility failures and neurological deficits are not so precisely determined like in the case of the GUV-evaluation since they are not so important in everyday life [5].

The complete damage is not compensated in the personal accident insurance which is interpreted as a sum insurance. The sum insured at the time of conclusion of a contract is authoritative for the amount of compensation. Basis of the determination is the idea of the disability, namely the economic consequences as a result of the accident by a ever lasting impairment. The results of an accident must be asserted and proved at least within a year plus 3 months [2, 3]. Thus it can be avoided that that calculable long-term damages are excluded. The assessment is aligned with the provable function damages. One assumes in the schedule of compensation that shaft injuries can cause permanent consequences for example axis deviation, rotation, malpositions, varus and valgus position, shortening, prolongation as well as stable or unstable pseudarthrosis [3]. Scars, joint injuries with participation of the bones, ribbons and cartilage also have to be decided besides neurological and motorical deficits. The assessment is carried out as fractions of amount of the determined extremity. This method makes the calculation of the compensation possible. So for example a loss 1/1 of a hand values 55 % of the sum insured or 1/1 loss of a leg values 40 % of the sum insured. So results of a proximal humerus fracture can be assessed following depending on the schedule of compensation [3, 4] (Table 22.3).
