Metatarsophalangeal joint implant MDI™

first toe joint

METATARSAL DECOMPRESSION IMPLANT Key Benefits Highly engineered articular surface with progressive decompression An angled bone cut to minimize weight-bearing and shear forces Minimal bone resection Flexible design made from inert, silicon elastomer with a long proximal and a shorter distal stem • Implant is a dynamic spacer to preserve proper joint space and alignment while early motion is started • Press-fit titanium grommets distribute load between the implant and poor bone quality Alternative Solution: • Oval shape matches the head anatomy and covers exposed bone and offers better distribution of forces • Plasma spray titanium coated for osseointegration • Instrumentation eliminates angular variables in metatarsal shaft by placing implant parallel to the long axis of the foot
