Muscle contracture can occur at any site in the body, but there is a recognised
condition involving contracture of the gracilis muscle in dogs. Surgical
treatment has been reported to result in dramatic improvement in 100% of cases
immediately post-operatively but there is recurrence in less than 6 months..
The cause is not known.
The disorder is seen primarily in German Shepherd Dogs and other large breeds.
It occurs in adults (2-11 years of age, mean 4.7 years).
Signsde a chronic, gradual onset progressive hindleg lameness
resulting in a short stride, outward rotation of the hock and inward turning of
the foot and stifle. Usually it is not possible to fully extend the stifle
because of the lack of stretch in the affected muscle.
Clinical signs inclu
The muscle may be painful when palpated and it feels atrophied and like a
firm tendinous band running from the pelvis to the caudal and medial stifle.
No satisfactory long term treatment
