โœฆ Synopsis


Abstract

An investigation of metallic intramedullary fixation devices commonly used in orthopedic surgery revealed that the screw threaded portions of these devices were foci for corrosion and fatique fractures. After several design change proposals, a spherical head was developed which could be incorporated onto the intramedullary nails which would eliminate these problems. An extractor impactor was also developed to enable this new design concept to be utilized in surgery. The design and device are described and displayed.
