[Percutaneous method for achilles tendon lengthening in treatment of spastic equinus deformity with progressive muscular dystrophy].

Surgical technique of percutaneous lengthening of Achilles tendon has been presented. Thirty-seven feet in 26 children have been operated on. There was no intraoperative inadvertent tenotomy or excessive lengthening, no complications occurred in the postoperative course. An average follow-up was of 18 months. The procedure resulted in 7 degrees of dorsal flexion on an average. The authors recommend this method in the treatment of the spastic pes equinus.
