Anatomical Shoulder Domelock System Study

Prior treatment

• Patient meets at least one of the contraindications:
  • Patient's physical conditions that would impair adequate implant support and/or prevent the use of an appropriately sized implant, e.g., previous surgery, insufficient quality or quantity of bone, neuromuscular compromise or vascular deficiency in the affected limb in sufficient degree to endanger the success of the intervention e.g., absence of musculoligamentous supporting structures, joint neuropathy or other conditions that may lead to inadequate skeletal fixation
  • Signs of infection
  • Severe instability secondary to advanced loss of osteochondral structure
  • Charcot's shoulder (neuroarthropathy)

Other illness

• Patients who have any condition which would in the judgement of the Investigator place the patient at undue risk or interfere with the study. Any patient who is institutionalized, or is a known drug abuser, a known alcoholic or anyone who cannot understand what is required of them

Other

• Patient is unwilling or unable to give consent or to comply with the follow-up program
• Patient is known to be pregnant or breastfeeding

• Patient is 18-80 years of age, inclusive
• Patient is skeletally mature
• Patient is suffering from severe shoulder pain and disability requiring unilateral or bilateral HSA or TSA based on physical exam and medical history
• Patient has failed conservative treatment
• Patient meets at least one of the following indications:
  • Advanced wear and tear of the shoulder joint resulting from degenerative, posttraumatic or rheumatoid arthritis if bone stock is adequate.
  • Avascular necrosis
  • Conditions consequent to earlier operations
  • Optional use in revision: in some medical conditions (e.g., early revision when adequate bone stock exists), the surgeon may opt to use primary implants in a revision procedure.
  • Additional criteria for retrospective patients:
• patient has been implanted with the Domelock system before site initiation visit.
• information available must include at minimum demographic information, the operative report and details of the device implanted.
