Avulsion of the lateral origin of the gastrocnemius muscle mimicking cranial cruciate ligament deficiency in a dog

Abstract

AbstractAvulsion of the lateral head of the gastrocnemius is an uncommon diagnosis. Nonetheless, it is a possible cause of lameness in dogs, and it could be misdiagnosed as a cranial cruciate ligament injury if a systematic approach to clinical case management is not followed. The treatment of choice for avulsion of the gastrocnemius is surgical stabilisation. The proximity to the peroneal nerve and scarcity of bone for purchase for stabilisation are surgical challenges. However, the stabilisation by a spiked washer and screw can yield an excellent outcome for return to function.
