Study summary

The objectives of this study are to obtain survival and outcome data on the Trabecular Metal Reverse Shoulder System when used in primary or revision reverse total shoulder arthroplasty.

Read the detailed description

The objectives of this study are to obtain survival and outcome data on the Trabecular Metal Reverse Shoulder System when used in primary or revision reverse total shoulder arthroplasty. This will be done by analysis of standard scoring systems, radiographs and adverse event records. Data will be collected and analyzed to monitor pain, function, and survivorship and to confirm the performance of the Trabecular Metal Reverse Shoulder System.

Performance will be evaluated by monitoring the frequency and incidence of adverse events as well as by assessment of the overall pain and functional performances, survivorship, health status and radiographic parameters of all enrolled study subjects who receive the Trabecular metal Reverse Shoulder System.

Pain and functional performance will be measured using the American Shoulder and Elbow Surgeons (ASES) Shoulder Assessment and the Single Assessment Numeric Evaluation (SANE), survivorship will be based on removal or intended removal of the device, health status will be determined by evaluation of the Short Form Survey12 (SF-12) as well as Adverse Events (AEs) and radiographic parameters analysis of x-rays.

Study population

Each investigator will screen from his/her patients who suffer from osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, ununited humeral head fracture, irreduciable 3-and 4-part proximal humeral fractures, avascular necrosis, gross rotator cuff dificiency or failed total shoulder arthroplasty (both glenoid and humeral components require revision) who meet the inclusion/exclusion criteria stated in the protocol

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patient is > 18 years of age;
  • Patient is skeletally mature;
  • Patient qualifies for primary or revision unilateral or bilateral reverse total shoulder arthroplasty based on physical exam and medical history including the following: osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, ununited humeral head fracture, irreducible 3-and 4-part proximal humeral fractures, avascular necrosis, gross rotator cuff deficiency or failed total shoulder arthroplasty (both glenoid and humeral components require revision);
  • Patient is willing and able to provide written ;
  • Patient is willing and able to cooperate in the required post-operative therapy;
  • Patient is willing and able to complete scheduled follow-up evaluations/questionnaires as described in the Informed Consent;
  • Patient has participated in the Informed Consent process and has signed the Institutional Review Board (IRB)/Ethical Review Board (ERB) approved informed consent.

Exclusion criteria

Exclusion Criteria:

  • The patient is a prisoner;
  • The patient is mentally incompetent or unable to understand what participation in the study entails;
  • The patient is a known alcohol or drug abuser;
  • The patient is anticipated to be non-compliant;
  • The patient has one of the following compromising the affected limb: a significant injury to the upper brachial plexus, paralysis of the axillary nerve or a neuromuscular disease compromising the affected limb which would render the procedure unjustifiable;
  • The patient has a local/systemic infection;
  • The patient is known to be pregnant;
  • The patient has marked bone loss;
  • The patient has a known sensitivity or allergic reaction to one or more of the implanted materials;
  • The patient is unwilling or unable to give consent or to comply with the follow-up program.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
