The Gorilla® HEvans® plate was designed for use with the Evans Calcaneal Osteotomy. The plate uses a 3 screw fixation construct to support the graft placed into the osteotomy and helps to prevent graft subsidence with subsequent loss of calcaneal length seen in the early post-operative period due to graft resorption.

The design allows for a single proximal screw to be placed in the calcaneus with two distal screws placed in the anterior fragment of the calcaneus. Dual point fixation at the distal fragment mitigates the prospect of rotation of the distal fragment with the calcaneocuboid anatomy. The posterior aspect of the plate is tapered to prevent peroneal tendon irritation in the location of the plate.

The HEvans® plate is low profile (1.1 mm), with a tapering of the thickness to 0.5 mm toward the end to prevent soft tissue irritation.
