Abstract
A reamer system is provided which includes a cannulated reamer holder, and a corresponding cannulated reamer, which, when assembled and operated over a drill pin secured in a manner axially aligned with the stem of the femoral joint, enables the accurate and controlled reshaping of the femoral joint. The reamer is made up of a cutting form and a central guide, in which the guide is supported at the center of the cutting form by a bar structure. The bar structure includes portions which connect to and extend radially between the central guide and a peripheral edge of the cutting form.
