Abstract
A bone buttress plate and a method of using the same to fixate a lateral surface of a fractured hindfoot calcaneus. The plate includes a main body, a first and a second leg, and an extension member. Each leg attaches to and extends from the main body. The extension member includes a yoke, a first arm, and a second arm. The yoke attaches to the main body and extends from the main body opposite to the legs. Each arm attaches to and extends from the yoke. The invention further includes a surgical method of fixating a fractured calcaneus exposed in a surgical theater, which includes providing a bone buttress plate including a main body, a first and a second leg, and an extension member. Each leg attaches to and extends from the main body. The extension member includes a yoke, a first arm, and a second arm. The yoke attaches to the main body and extends from the main body opposite to the legs. Each arm attaches to and extends from the yoke. The method then includes shaping the plate from a substantially planar configuration to an extent required for conformity to a lateral surface of the fractured calcaneus. The plate is then secured with mechanical fasteners to the fractured calcaneus, each mechanical fastener retentionally engaged with said bone buttress plate and an underlying region of the fractured calcaneus.
