ABSTRACT

M, Valentini S Case study:
myopathy of the Gracilis muscle in three German sheperd dogs, 9(2): 19-23, 2005 Online J Vet Res, 9 : 1-12,
2005. Myopathy of the gracilis
muscle in 3 German Sheperd dogs resulted in hyperflexion
and inwards rotation of the
tarsus. A
taut,
firm band was palpable
in the caudo-medial aspect of the thigh. Increased radiopacity
was observed between muscle and
the lower tendon
junction. Ultrasound revealed a normal or slightly echogenic muscle whereas electromyography showed normal or spontaneous
activity. Biopsies revealed a fibrous
cord along the muscles
caudal border and histopathology showed replacement
of degenerating myofibers with connective tissue. The findings were
consistent with primary myopathy due to polyphasic
muscular damage (degeneration, segmental necrosis, phagocitosis,
and fibrosis). After surgery,
the animals had normal
gait, but lameness recurred months later.
KEY-WORDS: German shepherd, myopathy, gracilis muscle,
histopathology.
