[Assessment of treatment results of extensor tendon injuries].

Criteria for evaluation of results after extensor tendon lesions are presented, which are easy to apply and based on angular measurements of active joint mobility. The scheme is analogous to the evaluation method for flexor tendon injuries published by Buck-Gramcko et al. in 1976 which is now widely used. A modification was necessary to treat the extension deficits more severely. A comparison is made to the evaluation method proposed by the Group of Erlangen, and both schemes are tested on 68 patients with extensor tendon injuries of different zones, various fingers and combinations. Lesions of the thumb require different criteria.
