Scope of Application

This cementless prosthesis is indicated for the replacement of the 2nd to 5th metacarpophalangeal and proximal interphalangeal joints in patients with osteoarthritis and rheumatoid arthritis unresponsive to conservative treatments and other non-surgical interventions.

Product Features

★The elastic fixation with a flattened double-stem design enables free adjustment of collateral ligament tension and enhances implantation stability.

★It can be screwed into the medullary cavity without bone cement, featuring simple operation and easy revision, which greatly shortens surgical time.

Product Advantages

• The curved sliding motion between the metal articular head and polyethylene platform maximizes the restoration of joint mobility while minimizing wear rate.

• The square step design of the articular head and platform significantly enhances anti-torsion performance.

• The multi-size design allows matching of appropriate specifications according to individual patient conditions, improving implantation compatibility.
