The Pseudo Jones Hook Plate has an innovative anatomic curvature for a secure fit.

Proximal tines spacing is compatible with the CoLag^® 3.0 Screw [available separately] when compression is needed. The Plate hooks are placed intraosseous, proximal to the fracture, to provide a means of reducing the avulsed fragment.

PRODUCT DESIGN / PROCEDURE SPECIFICS

5MS^® Forceps

For displaced fractures, use the provided 5MS Reduction Forceps for alignment and compression during provisional fixation. Use the Guide Wire to puncture the lateral cortex midshaft for insertion of the barbed end, with the curved end spiked into the proximal tuberosity. All provisional fixation must be located to not interfere with Plate placement.

Plate Placement

Place the Plate on the bone so the sharp Plate tines capture the avulsed fragment. Apply manual pressure so tines gain appropriate purchase. An Olive Wire placed in the distal end of the Guide Wire slot can be used to provisionally secure the Plate. Use the cannulated Pseudo Jones Plate Tamp to seat the tines securely into the bone.

Screw Fixation

Use the Non-Locking Drill Guide, Drill, Depth Gauge, and T7 Driver to install a Screw into the distal noncompression sliding slot.

OPTION: A 3.0 mm CoLag^® Screw may be placed between the proximal tines of the Plate. Place the remaining Screws.

Optional 3.0 CoLag^® Screw Placement

CoLag^® is a separate implant and instrument tray.

For additional stability of the avulsed fragment, it is recommended to place a 3.0mm CoLag^® headed compression screw between the Plate tines into the far cortex.

Drive the 1.1mm Guide Wire freehand or with the 1.6 non-locking Drill Guide in the direction of the 4th metatarsal metaphysis dorsal of the most proximal Plate Screw to the desired Screw depth. Use the Small Depth Gauge for measurement, placing the Gauge over the Guide Wire and against the bone between the tines. Remove the Depth Gauge and advance the Guide Wire slightly prior to drilling.

NOTE: Screw Head will seat into Plate tine counterbores. Increase the depth reading by 1-2mm due to the Plate/Screw interface.

Use the 2.0 Non-locking Drill Guide from the 5MS^® instrument tray with blunt end for Drill guidance to protect the Plate from the Drill flutes. Use the cannulated driver to place the Screw over the Guide Wire and through the Pseudo Jones Plate until it seats properly against the tines.
