ABSTRACT:
A dynamic compression nail for intramedullary compression nailing in treating the fractures of long bones includes a proximal part having at its distal end a central cylindrical recess open on the distal end and a central bore through the remaining portion of the part; a distal part having a tip portion and a portion attached thereto for insertion into said cylindrical cavity, the distal part also containing a central bore; a central axial compression shaft extending through the bores in the proximal and distal parts; a spring surrounding the shaft and acting between the proximal end of the cylindrical recess and the distal part biasing the distal part distally; at least one pair of sliding blades having on the side thereof pointed projections in each of the said proximal and distal parts, the sliding blades operatively coupled to the shaft by means of pins so that retraction of the shaft proximally will result in an outward projecting movement of the said sliding blades thereby permitting their projecting spikes to engage the bone; and means for moving said shaft.
