Flexor Tendon Graft / 대한정형외과학회잡지

ABSTRACT

Flexor tendon grafting is a well-proved procedure for the restoration of tendon defects in the hand. The results are not entirely predictable, it offers a good expectation of successful outcome. Authors have performed the tendon graft in thirteen cases of flexor tendon injury of the hand during the period from September '79 to January '82 and evaluated the results. The followings were the results obtained. 1. Male was eleven, female was two. Age distribution is from 4 to 38 years. 2. Injured fingers were thumb 6, index 2, middle finger 4 and little finger 1 cases. The site of the primary injury was on area of Bunnell's Zone II in all cases. 3. Time interval from tendon injury to flexor tendon graft was 6 weeks to 19 months (average 5.6 months). 4. The results of tendon grafts rated as excellent 2 cases and good 3 cases in preoperative Good group; excellent 1, good 3 and fair 1 in “Scar” group; fair 1 and 1 poor in “Joint” group; fair 1 in “Salvage” group. In the thumbs, the results were better than in the fingers. 5. Degrading the postoperative results were flexion contracture in 3 cases, lack of flexion ROM in 2 cases and bowstringing in 2 cases. 6. Pinch power of the finger where tendon graft was performed was 52% of that of the opposite healthy finger. 7. As complication, bowstringing was observed in 2 cases and recurvatum deformity of the PIP joint in one case.
