​NewPrim - Silktoe®

​Silktoe® is designed to offer a specialist solution for patients affected by severe arthritic diseases; with which arthroplasty of the metatarsophalangeal joint of the big toe is necessary. The device is made from elastomeric medical grade silicone; formed into a spacer with two titanium rings to replace the joint. The two titanium rings interface between the spacer and the bone sites where the device is positioned.
The spacer has two specific shaped stems:

• the distal stem, with trapezoidal section, which guarantees an anatomical adaptation with respect to the intramedullary canal of the phalanx;
• the proximal stem, with rectangular section, which helps adaptation to the intramedullary metatarsal canal.

The titanium rings are placed above the taproot and act as a support for the silicone joint spacer. Furthermore, they improve the stability of the spacer into the medullary canal. The hinge joint between the taproots restores the dorsiflexion movement of the toe and avoids the contact between the rings during the movement. The device is provided sterile and disposable. 
​
The intended use of the Silktoe® device is to represent a permanent implant, used in all severe forms of arthritis, such as:

• Hallux rigidus or hallux limitus;
• Painful rheumatoid arthritis;
• Hallux abducto valgus associated with arthritis;
• Unstable or painful joint from previous surgery
