Screw SystemsPhantom® Metatarsal Shortening System

The Paragon 28® Phantom® Metatarsal Shortening System was designed to provide fixation for an in-line, parallel shortening osteotomy of the lesser metatarsals. The system was designed to help eliminate potential complications that may arise from alternative osteotomies, such as post-operative floating toe, malunion of the metatarsal head, an altered distal articular surface, opening of the joint capsule, and/or the effects of an open capsulotomy.

The Phantom® Metatarsal Shortening implant is designed to thread into the distal metatarsal head after performing the desired osteotomy. The proximal end of the implant is then inserted into the exposed intramedullary canal and the osteotomy is compressed, completely enveloping the implant. Finally, a Ø2.0mm crossing screw is driven bicortically through the bone and proximal slot of the implant head to secure the shortening fixation.

The Phantom® Metatarsal Shortening System was designed with instrumentation to facilitate the procedure from start to finish. Cut Guides are available to allow for measured, parallel cuts, in 1 mm increments that range from 3 mm – 8 mm. Bone canal measurement tools are provided to allow for selection of an appropriately sized implant diameter. Drilling tools are provided to prepare both the distal and proximal aspects of the metatarsal osteotomy for implant placement. A Wire Guide is provided to help place the crossing screw proximally to secure the implant and impart additional stability.
