Mri Features of Gastrocnemius Musculotendinopathy in Herding Dogs

Abstract: Pelvic limb lameness that was localized clinically to the lateral gastrocnemius head was observed in dogs without history of trauma. The aim of this retrospective study was to describe magnetic resonance imaging (MRI) findings of this condition. Nine dogs were identified, eight Border Collies and one Australian Shepherd. They all had chronic pelvic limb lameness; no signs of joint effusion or instability were present. In MR images there was high signal intensity in the lateral head of the gastrocnemius muscle … Show more

“…As duas cabeças unem-se na parte proximal da perna e dão origem a um único tendão, que se insere na superfície dorsal proximal do calcâneo (Hermanson e Evans, 1993;Dyce et al, 1997). A ação principal do músculo gastrocnêmio é a extensão do tarso, mas ele também atua na flexão do joelho (Hermanson e Evans, 1993;Dyce et al, 1997;Stahl et al, 2010).…”

“…Lesões nas áreas distal e média são mais comuns, enquanto a região proximal é raramente afetada (Muir e Dueland, 1994). A avulsão das origens do músculo gastrocnêmio pode ser parcial ou total (Stahl et al, 2010). Poucos relatos têm descrito avulsões das cabeças lateral (Vaughan, 1979;Reinke et al, 1982;Prior, 1994; Ridge e Owen, 2005) ou medial (Chaffee e Knecht, 1975;Muir e Dueland, 1994), bem como avulsão bilateral da origem do músculo gastrocnêmio em cães (Robinson, 1999).…”

“…Similar observation reported Bottcher et al (2010) and their results for meniscal tears were 95%. Stahl et al, (2010) described effectiveness of MR imaging for gastrocnemius musculotendinopathy in dogs. MRI is also an effective technique for imaging neoplastic tumors in the area of the stifle joint and the articular capsule.…”
