Abstract
Devices, kits, and methods are provided for treating a bone structure, e.g., a vertebra, with a compression fracture. Wedges can be introduced into the bone structure in a direction that is lateral to the compression fracture, and stacked on tope of each to apply forces to the bone structure to reduce the compression fracture. The wedges can be introduced into the bone structure using a cannula. The wedges can be introduced as wedge pairs, in which case, a subsequent wedge pair can be introduced between a previously introduced wedge pair in order to drive the previously introduced wedges apart to create the stacking arrangement. Optionally, the wedges can be provided with longitudinal bores, in which case, they can be introduced into the bone structure, over a guide member that is threaded through the bores.
