Plantar Plate Repair

Evolution of Plantar Plate Repair

Plantar plate repair is performed through an incision over the MTP joint on the top of the foot, or the dorsal surface. The MTP joint is pulled apart to allow for visualization of the underside of the joint where the plate runs.

A tool is used to then separate the plate from the bottom of the metatarsal, allowing for it to be moved around more for repair. Because repair of the plate requires removing some of the injured plate the metatarsal bone needs to be shortened, so an intentional cut is made in the bone in order to shorten it and is then pinned in place. The injured plate is then removed, and stitches are placed in the free end of the remainder of the plantar plate.

Two holes are made in the phalanx and these stitches are passed through those holes and tied down. Screws are then placed in the metatarsal bone to fix the bone cut. This procedure can be quite difficult to perform without specialized tools given the very small space in which all of this work occurs. The use of this dorsal approach to fixing the plate is a more modern twist on classic repair options in which the cut was made on the bottom of the foot.

While the procedure is more difficult from the top of the foot, avoiding cuts and scars on the bottom of the foot should be avoided when possible because there are more nerves and important structures on the bottom of the foot, and scars are more painful on the bottom of the foot.
