NEW FORM OF OSTEOCHONDROSIS - APOPHYSEOLY SIS OF TUBER CALCANEI IN YOUNG ROTTWEILER AND DOBERMANN DOGS (SEVERS-DISEASE)

The so-called osteochondrosis dissecans syndrome of young dogs has bee n reported. This syndrome causes lameness mainly in dogs heavy in buil d. Localization of the alteration has been mentioned (osteochondrosis of caput humeri, condylus medialis humeri, processus coronoideus media lis et processus anconeus ulnae, caput et collum femoris, condylus lat eralis femoris, malleolus lateralis et medialis ossis tali and os sacr um). The above mentioned anatomical regions affected first of all the epiphysis (except for the lack of the fusion of processus anconeus). O nly the separation of tuberositas tibiae, the so-called Schlatter-Osgo od syndrome was known as an alteration affecting the apophyses. The Se ver's disease mentioned in this study means the apophyseolysis of tube r calcanei which can not be traced back to a traumatic cause. The alte ration has been diagnosed in 5 dogs until now (in 2 Dobermann and 3 Ro ttweiler dogs). The course of the disease is not uniform. In two cases sudden lameness white in 3 cases gradually progressing lameness devel oped. The successful therapy was based on a correct extension bandage immobilization which was combined with external fixation (fixateur ext erne) in more severe cases.
