Outer Foot Bone Fractures (5th Metatarsal Fractures): Screw Fixation With a Jones Screw Animation

This animated video demonstrates a surgical repair of a 5th metatarsal Jones fracture utilizing a Jones screw. Surgical repair with a single screw that compresses the fracture site will be used in this demonstration.

First, a small surgical incision will be made approximately 2cm from the base of the 5th metatarsal. A guide and a wire will be placed at the base of the 5th metatarsal. The wire will be advanced into the bone across the fracture site.

The wire will be left in place to use as a guide for the incoming drill bit. A drill guide and drill bit will then be introduced over the wire and drilled into the bone, following the same path as the wire. The drill bit will then be removed.

An instrument called a tap will be placed over the wire, and is used to pre-thread, or create a space in the bone, for the incoming screw. The length of the hole will be measured with a depth gauge, so the appropriate size screw is chosen.

The depth gauge and wire will be removed. The properly sized screw will be placed with a screwdriver until the screw is flush with the base of the bone. The surgery is now complete, and the incision will be closed.
