[Diseases of the Achilles tendon in dogs and cats]. / Achillessehnenerkrankungen bei Hund und Katze.

ABSTRACT

Dogs and cats rarely have problems with the Achilles tendon and if so, it usually results from a direct trauma. Prime area for injuries is the insertion on the tuber calcanei or directly proximal. One defers between complete and partial ruptures, acute and chronic injuries as well as displacement of the tendon of the superficial digital flexor muscle. In 38 cases (33 dogs and five cats) the clinical examination, radiology, ultrasonography and therapy are shown. Usually the clinical examination is sufficient for a diagnosis (hyperflexion of the hock and weight-bearing on the plantar surface of the metatarsus). The radiology primarily shows up abnormalities on the calcaneus, mineralisations of the tendon and allows the assessment of implants. Ultrasonography is the diagnostic imaging of choice for judgement of tendon diseases as well as the progress of their healing. Tendon suture is advisable if the rupture is open, fresh and/or complete and in cases of luxation of the superficial digital flexor muscle. Immobilisation of the tarsus in hyperextension seems to be of utmost importance no matter if an operative or conservative therapy is chosen.
