Abstract

Abstract This paper deals with wear of intramedullary milling cutters for the drilling of nail holes used for osteosynthesis of lower limbs long bones. After the physician’s complaints about the increasing resistance and total change of its properties that are caused by the reuse the instrument, we have designed a suitable methodology to verify and quantify this problem. The experiment was carried out on three types of milling cutters, differing in their diameter. Using statistical tests, we compared pressure force and torque before and after wear.
