Exactech Shoulder Post Market Clinical Follow-up Study

Inclusion Criteria:

• Patient is indicated for shoulder arthroplasty (or has previously undergone shoulderarthroplasty)

• Patient is skeletelly mature

• Patient is expected to survive at least 2 years beyond surgery

• Patient is willing to participate by complying with pre- and postoperative visitrequirements

• Patient is willing and able to read and sign a study informed consent form

Exclusion Criteria:

• Osteomyelitis of the proximal humerus or scapula; if a systemic infection or asecondary remote infection is suspected or confirmed, implantation should be delayeduntil infection is resolved

• Inadequate or malformed bone that precludes adequate support or fixation of theprosthesis

• Medial humeral bone loss resulting in compromised humeral stem fixation

• Proximal humeral bone loss extending distal to the surgical neck where there iscompromised humeral stem fixation

• Neuromuscular disorders that do not allow control of the joint

• Significant injury to the brachial plexus

• Non-functional deltoid muscles

• Patient's age, weight, or activity level would cause the surgeon to expect earlyfailure of the system

• The patient is unwilling or unable to comply with the post-operative careinstructions

• Alcohol, drug, or other subtance abuse

• Any disease state that could adversaly affect the function or longevity of theimplant

• Patient is pregnant

• Patient is a prisoner

• Patient is contraindicated for the surgery

• Revision cases in which a stemmed humeral component was used (Stemless ShoulderSystem)

• Metal allergy or sensitivity to the implants materials (Stemless Shoulder System)

• Acute fracture of the proximal humerus and displacement of the tuberosities,displaced three or four part fractures of the proximal humerus (hemi-arthroplasty),or acture fracture of the proximal humerus with failure of the glenohumeral joint (total anatomic shoulder arthroplasty) (Stemless Shoulder System)

• Acute fracture of the proximal humerus in combination with degenerative diseases ofthe glenohumeral joint and a grossly deficient, irreparable rotator cuff resultingin superior migration of the humeral head (reverse total shoulder arthroplasty) (Stemless Shoulder System)
