A trusted pre-fusion option

In the right patient, our implants have been proven to last 20+ years[9]. If complications do arise, studies show conversion from a failed hallux phalangeal hemiarthroplasty to arthrodesis have similar success rates to primary arthrodesis.[13]

The HemiEDGE

Potential complications of hemiarthroplasty include implant subsidence, bone overgrowth and implant migration. The HemiEDGE was designed to address these complications by encompassing the proximal phalanx with an overlapping edge around the medial, lateral and dorsal sides. The implant articulating surface remains consistent with the standard design.
