Eligibility Criteria

• * Patient is 18 years of age or older.
• * Patient must have signed Institutional Review Board (IRB)/Ethics Committee (EC)-approved informed consent.
• * Patient is a candidate for primary or revision total elbow arthroplasty, based on symptoms including at least one of the following:
• * Elbow joint destruction which significantly compromises daily living activities
• * Post-traumatic lesions or bone loss contributing to elbow instability
• * Ankylosed joints, especially cases of bilateral ankylosis from causes other than active sepsis
• * Advanced rheumatoid arthritis, post-traumatic, or degenerative arthritis with incapacitating pain
• * Instability or loss of motion when the degree of joint or soft tissue damage precludes reliable osteosynthesis
• * Acute comminuted articular fracture of elbow joint surfaces that precludes less radical procedures, including 13-C3 fractures of the distal humerus
• * Patient is willing and able to complete scheduled follow-up evaluations as defined by the protocol.
• * Patient must have undergone a total elbow replacement with the Nexel system between July 2013 and the date of the site initiation visit.

• * Patient has a currently active or history of repeated local infection at the surgical site.
• * Patient has a current major infection distant from the operative site.
• * Patient has a history of prior sepsis.
• * Patient suffers from paralysis or dysfunctional neuropathy at the elbow joint.
• * Patient has significant ipsilateral hand dysfunction.
• * Patient has excessive scarring near the surgical site, which could prevent adequate soft tissue coverage.
• * Patient participates in daily activities that may cause significant stress to an implanted device such as heavy labor, torsional stress, and/or competitive sports.
• * Patient is a prisoner.
• * Patient is mentally incompetent or unable to understand what participation in the study entails.
