Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This non-interventional clinical investigation is initiated for the purpose of long-term Post-Market Clinical Follow-up (PMCF) and the follow-up time of patients is expected to span from 6 months to \>20 years in function. It will collect and evaluate clinical data on the safety and performance of the OPRA™ Implant System when used on transhumeral amputees and within the scope of the intended use.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

All subjects that will be enrolled in this investigation should have been treated with the OPRA Implant System for a transhumeral unilateral or bilateral amputation and completed the second stage surgery (S2) and had at least 6 months of usage experience with the OPRA Implant System before enrolment.

This retrospective, non-interventional, clinical investigation is designed as a multicenter, multinational, cohort investigation for long-term follow-up of safety and efficacy endpoints. The investigation will also include prospective visit(s) for enrollment of subjects and collection of present data on device functionality and the use of the device.

No control group or comparator will be used in this investigation.

All patient reported outcome questionnaires used in the investigation will be available at the investigation site for completion by the subjects during one of the subjects' visits to the site. Depending on the subjects' preferences it will also be possible to provide those questionnaires to the subjects, through use of regular mail, email or through an electronic Patient Reported Outcome system (ePRO). It will be possible for the subjects to complete the questionnaires either on paper, electronically or over phone, depending on their preferences.

Preferably, the subjects prosthesis functional tests should be performed as part of the follow-up visit at the site. The tests may also be performed remotely, depending on subjects' preferences. If done remotely, this will require the functionality test being performed during a videoconference with the test administrator. No photos or video-recordings (if conducted according to the sites normal practice) of the performed tests will be part of the investigation documentation, only the related medical record notes will be used as source data for those parameters.
