Neglected ruptures of the Achilles tendon are uncommon, but they pose many difficult problems. Several surgical procedures have been attempted to bridge the gap after excising the intervening scar tissue. End to end anastomosis of ruptured Achilles tendon by making V-Y tendinous flap was done in 6 cases by authors between Dec. 1984 and Sep. 1988, and the result was analyzed. Postoperative power of triceps surae muscle was improved to nearly normal (5-5−) in five of the six patients, and only one patient had weak triceps surae muscle (4−) continuously. four of the six patients could raise their heels from the floor equally when on tip toe, whereas another two could walk without difficulty although when standing on their toes, heel to floor distance was less on the side operated than on the normal side. The calf atrophy was minimal, and active range of motion of ankle was within normal limit. There was neither re-rupture of Achilles tendon nor adhesion of the tendon to the skin. In conclusion, the V-Y tendinous flap procedure is easy to do, power of triceps surae muscle is well preserved by way of complete end to end anastomosis, and skin problem is very rare. We suggest that the procedure is recommanded for the treatment of neglected ruptures of the Achilles tendon in which end to end anastomosis is otherwise impossible.
