[ What is claimed is:] [1.]1. An implant for insertion in a material, the implant comprising:a shaft including a longitudinal axis, a proximal portion, and a distal portion, the proximal and distal portions having proximal and distal threads, respectively;with the proximal and distal threads being configured to threadably engage first and second spaced regions of the material, respectively, when the shaft is rotated in one direction about its longitudinal axis to bias the first and second regions of material with respect to one another to provide compression therebetween, and the proximal thread is configured to substantially inhibit biasing the first region when the shaft is rotated in an opposite direction about its longitudinal axis to substantially prevent tension between the first and second regions.
