Lavender Medical is pleased to introduce The Extremity Medical Trapezium Prosthesis.  The TrapEZX is a surgical implant indicated for use in degenerative or posttraumatic (e.g. following an old Bennett fracture) arthritis of the thumb trapezial-metacarpal (“basal”) joint with:

 

 

• Localized pain and palpable crepitus at the base of the thumb on the “grind test” (circumduction withaxial compression of the thumb)

 

• Decreased motion, pinch, and grip strength

 

• X-ray evidence of arthritic changes of the trapeziometacarpal joint; as well as trapezioscaphoid, trapeziotrapezoid, and trapezium-second metacarpal joints, singly or in combination.

 

• Associated unstable, stiff, or painful distal joints of the thumb, including metacarpo-phalangeal hypermobility or hyperextension

 

SURGICAL TECHNIQUE

 

The following surgical procedure is applicable for the size 1, 2, & 3 Right and Left side Extremity Medical Trapezium Prosthesis implants. All implants and instruments are laser marked to help distinguish between three different sizes. The only instruments specifi c to the implant(s) are the sizing trials. All other instruments used in the surgical technique are common access instruments that are readily available to a physician. The implant approximates the anatomy of the trapezium. The straight side represents the radial and thus most superficial side of the implant, and the angled side includes the articulations of the trapezoid and second metacarpal.  The scaphoid articulation slopes proximally on its volar side.
