[Functional results after reconstruction of severed flexor tendons by means of free flexor tendon grafts].

From 93 free flexor tendon grafts which have been performed in the years 1959--1976 because of flexor tendon laceration 85% could be reinvestigated after 6 years 10 months (average intervall). Three reinvestigation schemes for classification of the functional results were used (VERDAN/MICHON 1961, McKENZIE 1967, BUCK-GRAMCKO 1976). This had the advantage that marked differences in the classification schemes could be demonstrated. With 56% of very good and 22% of good results according to the classification of McKENZIE or 30% of very good and 26% of good results according to the classification of BUCK-GRAMCKO the results of free flexor tendon graft in the area of the thumb are significantly better than those in the fingers. In addition the relationship between the objective reinvestigation results of the operation and the subjective results appraised by the patients is demonstrated and shows that BUCK-GRAMCKO's classification comes closest to the patients evaluation.
