The surgical treatment of the divided FDP tendon, more than 6 weeks old, in zone 2 is reviewed in 50 patients. The method used was the excision of the divided FDP tendon and the insertion of a thin tendon graft. There were 50 patients in this study; 36 were male and 14 female, aged from 18 to 60 years. All patients were markedly disabled because of loss of strength of the involved finger. Follow-up ranged from 1 to 25 years following tendon grafting. In 35 patients plantaris tendon was used and in 15 patients palmaris longus. Definite advantages were found in using the tendon grafting procedure; strength, dexterity, pinch and grasp were markedly improved. Functional results were evaluated by the Boyes method, with the Pulvertaft method as a secondary assessment. Among the 50 patients, 80% had excellent and good results (excellent 32%, good 48%) and 20% fair.
