Health Sciences · Robert W. Jackson Arthroscopy
A metal device consisting of two interlocking components. The larger component, the side plate, consists of a hollow barrel, at one end of which a plate with two screw holes is attached at an angle.
The smaller component is a metal rod ending in a tip from which three narrow splines protrude radially. The rod portion is inserted into the barrel of the side plate, with the splined portion protruding from the end of the barrel opposite the angled plate.

This device is used to repair hip fractures. The rod-like portion is inserted through the neck of the femur into the ball of the hip where it is anchored in place by the splined tip. This nail or rod-like portion is then inserted into the barrel of the side plate, with the plate portion anchored to the femur by cortical screws.
The “dynamic” element refers to the capacity of the rod-like portion to slide within the barrel of the side plate. Hip fractures have a tendency to compress slightly as they heal. This dynamic element allows for this compression while preventing the anchored portion from breaking through the ball of the hip.
This item is in good cosmetic condition and appears to be unused. It has light signs of wear across its surface.
