The Smart Toe Implant:
The Smartest Solution to Surgically Correct Hammertoe

A) Distal Phalange

B) Interphalangeal Articulation

C) Proximal Phalange

A) Distal Phalange

B) Medial & Proximal Fused

C) Smart Toe Implant

D) Proximal Phalange

A) Before insertion, the implant is cooled by the surgical team.

B) After insertion, body heat expands and contracts the implant.

The recently introduced Angled Smart Toe implant provides a natural angle to the surgically corrected toe.


  • Rigid hammertoes, claw toes, mallet toes
  • Morton’s toe deformity (long toes requiring shortening)
  • Deviated or crooked toes
  • Arthritic toes
  • Hereditary conditions affecting toes 2-5

The Smart Toe memory implant was specifically developed by Memometal Technologies of France to help surgeons and their patients correct painful toe conditions more effectively than traditional surgical methods.

The new implant offers advantages from its material – a special alloy with shape-memory properties called NiTinol – and its one piece design.

For Patients:

  • Compressive properties promote bone union, stability and rapid healing
  • No healthy joint disruption (unlike screws)
  • No post-operative implant exposure – nothing external after surgery needed to maintain new joint position
  • Eliminates risk of “pin tract” infection (no open sore to invite infection, common to surgeries using a K–wire)
  • Less pain during healing

For Surgeons:

  • One piece implant (no “connection” required)
  • Easy and precise placement within the toe
  • Shape resists rotation
  • Fewer complications from non-union, rotation and infection

Memory Enhances Stability and Healing
The goal of corrective surgery is to straighten and align the toe, ensuring the bones fuse in the right position. The Smart Toe implant helps achieve proper fusion because of the compressive properties made possible by its temperature-activated material, NiTinol alloy. The implant is cooled prior to surgery, and once implanted, body heat expands its width and shortens its length. Expansion secures the implant in place, while the shortening pulls the bones tightly together to encourage the natural fusion process.

Further studies are in progress to document the advantages of this procedure compared with traditional correction techniques. Consult with your podiatrist or orthopedic foot doctor to discuss whether the Smart Toe implant is an option for you.
