Exactech Shoulder Post Market Clinical Follow-up Study

Primary outcomes

• Constant [Through study completion, an average of 1 per year]: Constant Shoulder Score - 100 points scale about pain, Activities of daily living, Strength test, and Range of Motions questions about shoulder where 100 % corresponds to the highest pain
• ASES [Through study completion, an average of 1 per year]: American Shoulder and Elbow Surgeons Score (ASES) - 100 points scale about shoulder pain and performance evaluation in activities of daily living where 100 indicates the best shoulder condition
• Oxford Score (may be used as an optional form for surgeons in the United Kingdom) [Through study completion, an average of 1 per year]: Oxford Shoulder Score (OSS) - 12 questions assessing outcomes of shoulder surgery and its impact on patients' quality of life of degenerative conditions such as arthritis and rotator cuff problems - Maximum score is 60 and indicates greater degree of disability
• TESS (may be used as specific forms related to the pre-operative condition/diagnosis) [Through study completion, an average of 1 per year]: Toronto Extremity Salvage Score (TESS) - Patient functional assessment following for surgery for musculoskeletal tumors (Humeral Reconstruction Stem only) - 100-point score where higher score indicates a better outcome
• MSTS (may be used as specific forms related to the pre-operative condition/diagnosis) [Through study completion, an average of 1 per year]: Musculoskeletal Tumor Society (MSTS) - 30 points \[6 times (range 0-5)\], simple measure of the upper extremity function (Humeral Reconstruction Stem only) - The maximum corresponds to the best score

Sex: All, ages: 21 Years to any

Inclusion Criteria:

* Patient is indicated for shoulder arthroplasty (or has previously undergone shoulder arthroplasty)
* 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 visit requirements
* 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 a secondary remote infection is suspected or confirmed, implantation should be delayed until infection is resolved
* Inadequate or malformed bone that precludes adequate support or fixation of the prosthesis
* Medial humeral bone loss resulting in compromised humeral stem fixation
* Proximal humeral bone loss extending distal to the surgical neck where there is compromised 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 early failure of the system
* The patient is unwilling or unable to comply with the post-operative care instructions
* Alcohol, drug, or other subtance abuse
* Any disease state that could adversaly affect the function or longevity of the implant
* Patient is pregnant
* Patient is a prisoner
* Patient is contraindicated for the surgery
* Revision cases in which a stemmed humeral component was used (Stemless Shoulder System)
* 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 of the glenohumeral joint and a grossly deficient, irreparable rotator cuff resulting in superior migration of the humeral head (reverse total shoulder arthroplasty) (Stemless Shoulder System)
