The purpose of this study is to perform a five-year, multi-center prospective evaluation of the Discovery™ Elbow System for outcome and durability. Relief of pain and restoration of function will determine long-term clinical outcome while durability will be measured by the absence of revisions.

Discovery™ Elbow
Discovery™ Elbow minimally constrained

Detailed Description:
Patient follow-up outcomes measured by the ASES score, radiographs and adverse events/revisions.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients in need of relief from painful or disabling Joint Disease in need of total elbow replacment.

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.
