Fig. 1From: The primary stability of different implants for intra-articular calcaneal fractures: an in vitro studySchematic of the testing equipment. A round polyester resin platform was placed on top of the talus, and the calcaneus was firmly fixed into the jig. This positioning of the calcaneus was maintained with polymethylmethacrylate. The force on the calcaneocuboid joint was measured by a load-cell sensor. A pre-programmed material testing machine controlled the compressive loadingBack to article page
