Surgical treatment of a complicated distal tibia epiphyseal Salter–Harris type I fracture in a yearling

This article describes the management of a complicated distal epiphyseal Salter–Harris type I fracture of the left tibia in a yearling horse. Closed reduction and internal fixation was attempted in the first surgery using tension band wires. Due to fracture instability 2 weeks after surgery, a full‐limb transfixation pin cast was applied to the tibia and maintained for 7 weeks to prevent further fracture displacement and to achieve axial alignment. The full‐limb cast was maintained for a total of 12 weeks, including the time with the transfixation pin cast. Cast sores and tendon laxity resolved without further complications. Ten months after the first surgery, the fracture had radiographically healed, and the horse was sound at the walk and trot in a straight line

Fixação interna de fratura de epífise proximal de tíbia em potro Internal fixation of the tibial proximal epiphyses fracture in a foal

A fratura Salter Harris tipo II ocorre comumente na epífise proximal de tíbia em potros e tem reparação difícil mas com o advento das técnicas de fixação interna, o prognóstico tem melhorado. No caso descrito, em um potro da raça árabe de 26 dias de idade, com fratura proximal de tíbia direita tipo Salter Harris II, foram utilizadas as placas de compressão para garantirem estabilização e aproximação dos fragmentos fraturados, porém com risco de ocasionar distúrbios no desenvolvimento esquelético. No caso relatado, através do controle radiológico, não foi evidenciada diminuição da radioluscência na região correspondente à cartilagem de conjugação proximal da tíbia. O artigo tem como objetivo discutir o tratamento empregado que se mostrou como alternativa viável pelo resultado favorável com bons resultados.<br>The most frequent fracture is tibia’s proximal epiphysis in foals is Salter Harris type II although its difficult to repair. The development of the inner fixation technique has been made the prognosis better. The dynamic compression bone plate allow guaranteed reduction and stabilization of the bone’s fragments, but it can promote development disturbs. In this case, by the radiological control, it has not shown less radiolucency in the proximal tibia’s growth plate. The treatment used showed itself as a feasible alternative because of the favourable good results
