Intervention Details:

Total elbow arthroplasty using discovery elbow replacement

Detailed Description:

About 3 years ago, Biomet engineers began developing a completely different elbow system. They focused on problems of past elbow designs, including:

Poor anatomic stem design
Poorly reproduced elbow hinge mechanics
Unrefined, cumbersome instrumentation, difficult technique reproduction
Excess wear on hinge bearing
Low-grade polyethylene
Bearing difficult to service/revise
Poor preservation of bone around the hinge With these challenges in mind, the Discovery™ Elbow began to take form.

Discovery™ design goals:

Anatomic design
Restore joint mechanics
Long lasting hinge
Accurate, user-friendly instrumentation

The rationale behind the Discovery™ Elbow was to create a device that closely matches the anatomy, while providing a superior hinge mechanism that is easier to assemble and revise should it become necessary. It was also a priority to create an instrument set that was ideal for a broad range of surgeons.

Eligibility

Ages Eligible for Study:	18 Years and older
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis.
Inflammatory arthritis
Revision where other devices or treatments have failed
Correction of functional deformity
Treatment of acute fractures or non-union about the elbow

Patient Selection Factors to be considered include:

Need to obtain pain relief and improve function
Ability and willingness to follow instructions including control of weight and activity levels.
Patients who are able and willing to return for follow-up evaluations.
Patients with a good nutritional state.
Patients with full skeletal maturity.
Patients of all races and gender.
Patients who are able to follow care instructions.

Exclusion Criteria:

Patients less than 18 years.
Patients with marked bone loss which would preclude proper fixation of the prosthesis.
Metabolic disorders, which may impair bone formation.
Patients who are pregnant.
Patients with an active or suspected infection in or around the elbow or distant foci of infections, which may spread to the implant site.
Patients with a highly communicable disease or diseases that may limit follow-up (e.g. immuno-compromised conditions, hepatitis, active tuberculosis, neoplastic disease, etc.).
Patients unwilling or unable to comply with a rehabilitation program for elbow replacement or who indicate difficulty or inability to return for follow-up visits prescribed by the study protocol.
Patients who qualify for inclusion in the study, but refuse consent to participate in the study.
