Repair of chronic Achilles tendon rupture with flexor hallucis longus. A, Two incisions are made. Medial midline incision on midfoot is used to harvest flexor tendon. Posteromedial incision anterior to Achilles tendon is used to expose tendon. B, Hole is drilled just deep to Achilles tendon insertion and is directed plantarward. Second drill hole is made from medial to lateral to intersect first drill hole midway through posterior body of calcaneus. C, Flexor hallucis longus is woven through remaining portion of Achilles tendon for secure fixation and supplementation of tendon. SEE TECHNIQUE 48.19.
