About the NeuFlex PIP Joint Implant

The NEUFLEX MCP and PIP Finger Joint Implant Systems features implants made from silicone. The systems incorporate the anatomically shaped implant, ergonomically designed instruments and an enhanced skin incision procedure. These innovative systems offer the medical community superior technology when compared to competitive designs. The NEUFLEX MCP and PIP joint systems assist in restoring function and quality of life to patients with rheumatoid, degenerative or traumatic arthritis.

Implant geometry provides for flexion in the hinge region, which greatly reduces pistoning and abrasion and eliminates the need for grommets.

The PIP design also allows for 15 degrees of added extension needed to replicate normal human hand function using minimal patient effort.

The preformed, anatomically neutral angle (30 degrees in the MCP, 15 degrees in the PIP) approximates the relaxed position of the human hand at optimal flexor/extensor tendon resting tone.

In the MCP design, the maximum bending action needed is 60 degrees to achieve full flexion, versus 90 degrees for a straight-stemmed, hinged silicone implant. This reduces strain by 30-35 percent, and promotes longer fatigue life and the possibility to achieve greater finger flexion and, thus, function.¹

The anatomic shape provides fit and fill within the canals and helps decrease the likelihood of dislocation.

The hinge section for the PIP design has been carefully engineered to further reduce material strain at 90-degree flexion. Gas plasma sterilization does not alter the implant’s material properties.

Advanced Flexion

NEUFLEX® MCP and PIP anatomic implants are designed to provide patients with a range of motion from 30-90 degrees. The NEUFLEX MCP implant is designed with a neutral angle (30 degrees) to approximate the joint at rest while still allowing extension. At full flexion, the implant has 30-35 percent less strain than competitive straight joint designs.1 Throughout the full range of motion, the NEUFLEX MCP implant bends at the hinge, reducing pistoning and the need for grommets.

About the Small Bone Fixation System

The Small Bone Fixation System (SBFS™) is a percutaneous locked flexible intramedullary nail system for fractures of the long bones in the hand and foot.

  •Pre-sterile, self contained system

  •Minimizes surgical dissection, fracture exposure and dorsal
   hand scar

  •Simple surgical technique

  •Proximal lock stabilizes rotation and length while providing 3-point
   fixation

  •Implantable nail cap cover the cut nail while helping minimize soft
   tissue irritation

About the Strickland Hand Table

The Strickland Hand Table was developed by DePuy Orthopaedics in conjunction with Dr. James Strickland. The first product of its kind on the market, this stainless steel tabletop tray helps keep the operating area open, thus reducing the number of necessary OR support staff. The patient’s hand is placed on the table and secured with hook-and-loop fasteners, while finger splints secure the patient’s fingers. The porous surface of the table allows for easy drainage of fluids during the procedure.
