[Significance of the preoperative status in the evaluation of results of the reconstruction of extensor tendons].

Since 1977, a new evaluation scheme that is simple to use and which provides more objective information than earlier plans has been employed for the assessment of the results of extensor tendon reconstruction. The results in the four groups were evaluated and given a prognosis in accordance with the newly developed scheme. This permitted not only a better differentiation of the value of the therapeutic procedures, but also allowed one to make prognostic predictions. The prognosis is also of particular importance during preoperative talks with the patient.
