Integra® Silicone MTP Toe Replacement System

The Integra® ForeFoot Arthroplasty products are a fourth generation silicone polymer, which has higher tensile strength, tear and abrasion resistance than the competitors' silicone offerings*. Each implant is designed for the individual biomechanics of the specific joint. Additionally the instrumentation is simple, and straight forward to ensure reproducibility of the procedure.

Integra® Primus Flexible Great Toe (FGT)

The Integra® Primus Flexible Great Toe (model FGT) is a third generation implant for supplementation of first metatarsophalangeal joint arthroplasty. The implant is constructed from medical grade silicone elastomer and includes titanium grommets.

The first double-stemmed implant.
The Primus is the first double-stemmed implant designed especially for the unique geometry of the first metatarsophalangeal joint. With its dorsal-offset metatarsal aspect, the Primus matches the anatomic position of the proximal phalanx relative to the metatarsal.

Features & Benefits
  • Angled cuts preserve insertion of short tendon flexor
  • Stems match anatomy of intramedullary canals
  • Titanium grommets and strength rib on hinge enhance durability
  • Axially offset hinge offers 95 degree range of motion and prevents the grommets from contacting each other.
  • The trapezoidal stem cross section matches the anatomy of the intramedullary canal.
  • Angled proximal stem corresponds with natural metatarsal declination angle.

Integra® Classic Flexible Great Toe (CGT)

The Classic Flexible Great Toe implant is a third generation prosthesis designed to supplement first metatarsophalangeal joint arthroplasty. Constructed from medical grade silicone elastomer, the Classic offers a patented axial offset hinge and other advanced design features while maintaining the surgical technique of the previous generation joint replacements.

Third generation implant.
Instrumentation is also simplified with only a trapezoidal and rectangular broach necessary to prepare the intramedullary canals.

Features & Benefits
  • Anatomically correct axial offset hinge. The metatarsal stem is elevated relative to the phalangeal stem.
  • The stem geometry is optimized for the unique anatomy of the intramedullary canals of the phalanx and metatarsal bones.
  • The hinge incorporates a reinforcing strength rib.
  • The CGT offers a more functional and durable implant to those surgeons who do not wish to alter their joint resection technique.

Integra® Lesser Metatarsal Phalangeal (LMP)

The Integra® Lesser Metatarsal Phalangeal Joint Implant is the first prosthesis designed specifically to supplement lesser metatarsal phalangeal joint arthroplasty. Constructed of medical grade silicone elastomer, the implant features stems designed to fit the intramedullary canals of the proximal phalanx and the lesser metatarsal. The LMP is offered in four sizes and is supported by a custom instrumentation set.

Features & Benefits
  • Supplement lesser metatarsal phalangeal joint arthroplasty.
  • The distal hinge buttress is anatomically designed to fit the contours of the proximal phalanx.
  • Bone resection is limited to a simple vertical cut.
  • The hinge design allows for excellent range of motion without stressing the prosthesis.


Silicone elastomer implants are designed to assist in joint arthroplasty. Clinical indications for use of these devices include:

  • Rheumatoid Arthritis
  • Osteoarthritis
  • Ankylosed joints, or those with limited range of motion which have not responded to conservative treatment
  • Nonfunctional joints due to inadequate bony alignment and joint space whic cannot be restored by soft tissue reconstruction alone
  • Destroyed articular surface(s)


General contraindications for the use of these implants for joint reconstruction include:

  • A psychologically unsuitable patient
  • A patient with skin, bone, circulatory and/or neurological deficiency
  • Nonfunctioning and irreparable musculotendinous system
  • Active sepsis
  • Inadequate bone stock
