 Anatomic
Design:
|
Anatomic Implant shape and easy-to use instrumentation promote implant alignment, stability and restored joint kinematics
|
- Bone removal is minimized
- Critical soft tissue
structures are preserved
- Anatomic bone alignment is
restored
- Functional joint mechanics and
range of motion are re-established
|
|
Indications
:
|
The Ascension MCP is intended for use as a total joint replacement of the metacarpal phalangeal (MCP) joints in cases of:
|
- Rheumatoid arthritis
- Osteoarthritis
- Post-traumatic arthritis
- Ankylosed joints or those with limited range of motion
which have not responded to conservative treatment
- Nonfunctional joints due to inadequate bony alignment and
joint space which can not be restored by soft tissue
reconstruction
- Destroyed articular surfaces
|
Contraindications:
|
Include:
|
- Physiologically unsuitable patient
- Skin, bone, circulatory and/or neurological deficiency
- Non-functioning and irreparable musculotendinous system
- Indications of active sepsis or infection
- Inadequate bone stock
|
Implant Stability:
|
PyroCarbon's biochemical and biomechanical compatibility promotes osseous integration resulting in a stable bone/implant interface
|
- inert nature of PyroCarbon eliminates
concern with silicone
and other less biocompatible materials
- No cement required eliminating potential complications
|
Elastic Modulus of metal is much greater than that of bone or PyroCarbon
PyroCarbon minimizes bone loss due to stress shielding
