Percutaneous Z Tendon Achilles Lengthening



Achilles tendon lengthening is a delicate procedure whereby the risk of over lengthening (creating calcaneus), rupture, and weakening of the gastrocnemius-soleus muscle is devastating. The Silfverskiöld test is clinically performed to differentiate gastrocnemius equinus from gastrocnemius-soleus equinus. Many surgical techniques have been developed to treat negative results of the Silfverskiöld test. The authors prefer a gastrocnemius-soleus recession in order to preserve muscle strength. However, when a large amount of equinus deformity is present, an Achilles tendon lengthening is performed in order to achieve an adequate amount of length.1 The authors present a percutaneous technique for Achilles tendon lengthening.2
