Benefits of technology

The invention provides a surgical repair system and technique for complete plantar plate repairs. This system helps to reconstruct the plantar plate through a dorsal incision, which helps to restore the normal alignment of the joint and minimize healing complications. Overall, this invention aims to provide a more effective and minimally invasive surgical repair technique for plantar plate instability in the second MTP joint.

Problems solved by technology

Deterioration of the plantar plate often leads to instability of the second MTP joint.
Primary repairs involve direct visualization of the plantar plate injury and may involve an incision through the plantar of the foot which may lead to complications during healing.

Embodiment Construction

[0056]The present invention provides systems and methods for plantar plate repair. The systems of the present invention include surgical instruments that confer enhanced repair (a tensioned plantar plate), while decreasing the chance of wound complications and plantar tissue trauma.

[0057]An exemplary method of plantar plate repair employing a dorsal approach and combining a Weil osteotomy in accordance with the present invention comprises inter alia the steps of: Weil osteotomy is performed allowing the capital fragment to be recessed under the metatarsal; digital distraction is obtained using a distraction clamp over K-wires; the plantar plate is assessed and repaired using suture (with a novel suture passing hand instrument known as the Mini Scorpion DX—this device allows the surgeon to pass suture through the plantar plate); the plantar plate is repaired back to the proximal phalanx. According to this method (the Complete Plantar Plate Repair or the CPR method), surgeons now have...

Abstract

Surgical repair systems and techniques for plantar plate repairs. The surgical repair systems and methods reconstruct the plantar plate through a dorsal incision. The surgical repair system embodies a variety of instruments that provide visualization and access to the plantar plate using suture to complete the repair. The repair system may include some or all of the following instruments: a metatarsal head pusher employed in open surgical space, to move the “capital fragment” in a controlled manner; a suture retriever instrument and a suture retriever funnel (sleeve); a suture passer such as a Mini Scorpion DX and accompanying needle, or a variety of shaped Micro Suture Lassos; a measuring guide; and a small joint distractor.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 583,915 filed Jan. 6, 2012, the disclosure of which is incorporated by reference in its entirety herein.FIELD OF THE INVENTION[0002]The present invention relates to surgical devices and methods, and more particularly, to systems and methods for complete plantar plate repairs.BACKGROUND OF THE INVENTION[0003]The second metatarsophalangeal (MTP) joint is stabilized by a combination of static resistance provided by the plantar plate and collateral ligaments, and the dynamic pull of the intrinsic flexors. The plantar plate is rectangular to trapezoidal and originates on the metatarsal head through a thin synovial attachment, just proximal to the articular surface, and inserts on the base of the proximal phalanx. Deterioration of the plantar plate often leads to instability of the second MTP joint.[0004]As the principle stabilizer of the MTP joint, the integrity of the ...
