Exactech Shoulder Post Market Clinical Follow-up Study
What this study is about
The objective of this study is to collect and evaluate long-term clinical and radiographic outcomes data in order to better understand the safety and performance of the shoulder arthroplasty over time. This study will follow subjects long-term for a minimum of 10-years, without an early-term restriction on the amount of time they will be followed.
View original scientific description
The objective of this study is to collect and evaluate long-term clinical and radiographic outcomes data in order to better understand the safety and performance of the shoulder arthroplasty over time. This study will follow subjects long-term for a minimum of 10-years, without an early-term restriction on the amount of time they will be followed.
Primary outcome measures
Constant
Time frame: 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
Time frame: 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)
Time frame: 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)
Time frame: 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)
Time frame: 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
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
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)

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
