Disposable external fixation device

摘要

A novel disposable axial external fixation device for reducing bone fractures, of the type comprising an extendible rod-like middle body and oppositely located bone screw clamps which are articulated to the respective ends of the rod like middle body by means of ball joints. Advantageously, a ball-and-socket joint is mounted to each clamp within a main body with which a clamping mechanism for clamping bone screws clamping is associated or co-operates. Also provided is an ancillary member adapted for releasable association with one end of each clamp to better adapt each clamp for use in different conditions of installation of the fixation device.
