On the basis of computer tomographic investigations of 28 patients with subcutaneous ruptures of the Achilles tendon in different terms after the injury and its restoration by means of open and transcutaneous suture there have been revealed possibilities of the method. Computer tomographic syndromes of the tendon damage (increase of diameter by 2-3 times, spherical form of the cross section, density decrease, presence of hematoma, deformation of the front outline of tendon) and the signs of its continuity restoration have been determined. Identity of the computer tomographic data of comparison of tendon centres by open and closed sutures has corroborated reliability of the obtained criteria. Computer tomographic investigations in dynamics testify to significant changes in damaged tendon and +para-tendon tissues as well as to the duration of the process of its healing.
