Proximal Interphalangeal Implant – DGT PIP
The DGT PIP is a proximal interphalangeal implant that treats osteoarthritic pain while allowing a more conservative solution to osteoarthritis treatment. Indeed, the DGT PIP implant is indicated for use in primary arthritis, arthritis disease, and root arthritis with associated pain and reduced function of the finger.

The DGT PIP implant is available in cementless styles. The implant is semi-constrained, with an intraprosthetic guide stem and metal to metal friction torque.
The DGT PIP is manufactured from stainless steel. The implant is covered with porocoat cobalt chrome.
DGT PIP implants undergo a Kolsterisation in order to increase friction and wear resistance.
DGT PIP is designed to be implanted without cement, however cement may be used if deemed necessary.
Benefits:
- Treats osteoarthritic pain
- Range of motion allowing up to 90° flexion and a quasi-complete extension
- Maintains digital column length and allows normal joint function
- Preserves joint stability with aid of the guide stem
Indications:
- Primary arthritis
- Arthritis disease
- Root arthritis with associated pain and reduced function of the finger
Silicone MCP
The MCP and PIP Soft Skeletal Implants, constructed of Silflex II advanced elastomer, offer post-surgical results unavailable in any other finger joint implants.
• Accommodates the specific, unique biomechanics and anatomy of the MCP and PIP joints
Joint Specific Design
Volar Hinge Axis
• Creates an anatomical balance between the flexor and extensor mechanisms allowing full extension and flexion without volar impingement
Hinge Exterior
• In conjunction with the volar hinge axis, the hinge exterior design prevents volar impingement during flexion MCP and PIP Soft Skeletal Implants, constructed of Silflex II advanced elastomer, offer post-surgical results unavailable in any other finger joint implants.
Interior Hinge Radius
• Circular radius reduces point stresses in
the hinge by directing the stress over a
wide area as flexed
Hinge Block Buttress
• Impedes bony overgrowth by providing full seating for the resected bone
surface, eliminating the need for cumbersome grommets
Squared Implant Stems
• Provide rotational stability and allow for more precise anatomical placement
Silicone PIP
The PIP Soft Skeletal Implants, constructed of Silflex II advanced elastomer, offer post-surgical results unavailable in any other finger joint implants. The anatomic design highlights a volar hinge / one-piece spacer (reduces ulnar drift and correct deformities), restores hand functions, eliminates pain and improves cosmetics in lower demand patients with easy to use color-coded instrumentation. The silicone PIP has 10 degree flex to it (eliminates load placed on device & eliminates stress to the hinge when hand is in neutral position).

MCP Ariadna
The MCP Ariadna is an implant indicated for use in Rheumatoid arthritis, psoriatic arthritis, infectious arthritis, spondylitis, post-traumatic diseases and joint injury. The implant permits metacarpophalangeal joint replacement.
The MCP Ariadna implant is comprised of a distal and a proximal component. The implant is designed in different sizes.
The proximal component is an articulated stem that allows a link between distal and proximal components.
The MCP Ariadna is manufactured in from stainless steel. The implant is covered with porocoat cobalt chrome.
MCP Ariadna implants undergo a Kolsterisation in order to increase friction and wear resistance.
MCP Ariadna is designed to be implanted without cement, however cement may be used if deemed necessary.
Indications:
- Rheumatoid arthritis
- Psoriatic arthritis
- Infectious arthritis diseases
- Spondylitis
- Trauma diseases
- Joint injury
MetaFLEX
Percutaneous Flexible IM Nail System for Metacarpal and Metatarsal Fractures
Facilitating Improved Results for Both Metacarpal and Metatarsal Fractures
• Simple, minimally invasive procedure
• Unique shaped design to provide centering in varying diameters of IM canals
• Color coded titanium wires for easy identification of size
• Cost effective treatment of simple metacarpal or metatarsal fractures
• Use of two MetaFLEX wires improves stability over one slightly larger wire
Diamond™ Carpal Fusion Plate
The Diamond™ Plate is designed for four corner fusion of the capitate, hamate, lunate and triquetrum bones in the hand. The plate is intended for use in patients suffering from pain and/or loss of function due to SLAC and SNAC wrist, post-traumatic arthritis, fractures, carpal instability or rheumatoid arthritis. When combined with the specially designed screws included in the system, the plate acts as a compression device, providing secure fixation with only four screws.
Features / Benefits
- Low profile design – less bone removal
- Compression plate – fewer screws are needed to obtain fusion, making the process less invasive
- Specially designed screws allow optimum fixation
- Large central opening for better bone graft placement / manipulation
SR™ MCP
The SR™ MCP (Metacarpophalangeal) Implants are designed with the intention of minimizing bone resection and retaining critical ligamentous attachments. The SR™ MCP implant design features semi-constrained articular surfaces to ensure joint integrity while offering restored function. To further replicate normal joint kinematics, the SR™ MCP implant provides greater radial/ulnar stability through flexion, particularly past 60 degrees where joint forces tend to be greatest. In two separate studies, wear and fatigue testing of the SR™ MCP implant demonstrated favorable structural performance which may translate to longer implant life with proper surgical technique.
SR™ PIP
The SR™ PIP (Proximal Interphalangeal) Implants (formerly known as AVANTA RMS) are designed to replicate the anatomic joint surfaces, preserve bone and minimize disruption to the collateral ligament origins and insertions. The kinematic behavior closely mimics that of a normal joint when the soft tissues are well preserved.
The SR™ PIP (Proximal Interphalangeal) Implants consists of two pieces. A ultra-high molecular weight polyethylene (UHMWPe) component and an titanium alloy stem that has a external surface to allow bone growth.
The cobalt chromium surface articulates with the UHMWPe component to form a semi-constrained prosthetic replacement for the proximal interphalangeal joint. The implant is available in five sizes, each of which can be used in right or left hands. A range of trial sizers for each type of implant is available to aid in bone preparation.
The SR™ PIP is approved for use with or without cement. Therefore it is cement optional.
• Designed to replicate anatomic joint surfaces, preserve bone, & minimize disruption to the collateral ligaments
• Pain Relief – Recent studies have concluded that the anatomic designs of the SR family of finger implants can provide pain relief & restore joint kinematics for patients requiring finger joint arthroplasty
• Extended Range of Motion – ROM & function may be restored without artificial constraints or damage to ligaments or tendons
• Stable, Long Lasting – The congruent semi-constrained articular surfaces minimizes stress concentrations, allowing the implants to withstand the demands of everyday hand functions
• Proven Materials – These unique two-piece designs utilize the same proven biocompatible materials found in hip and knee replacements; cobalt chrome, titanium alloy & UHMWPe
• Anatomic Sizing – Each implant is available in multiple sizes to address varied patient anatomy
