Primary suture for flexor tendon rupture in zone II has become popular and we have experienced 76 fingers of 62 cases in the past 6 years and 6 months. Primary suture has been done by Tsuge's method using 4-0 or 5-0 looped nylon. Postoperatively, either plaster fixation for three weeks or Kleinert's early controlled exercise method has been done.Functional results of flexor tendon suture were assessed in 58 fingers of 46 cases followed over 6 months postoperatively. The results were evaluated with methods of both %TAM (proposed by Evaluation Comittee of the Japanese Society for Surgery of the Hand) and Buck-Gramcko's.Results are as follows:1) Either excellent or good results were obtained in 27.6 %according to the %TAM, and 72.4 %according to the method of Buck-Gramcko.2) Children had better results than infants and adults.3) Rupture on the proximal side had better results than that on the distal side.4) There was no significant difference among the methods of primary, delayed primary and secondary sutures.5) Cases with bone and joint injuries, crush injuries, infections and reruptures had poor results.6) Cases with FDS repair had better results than that without FDS repair.7) Cases performed early exercise had better results.
