Brief summary
This study is designed as a multi-center, nonrandomized, uncontrolled, unblinded, prospective clinical outcomes investigation to evaluate the short, mid and long term performance of the PyroTITAN™ HRA Shoulder prosthesis humeral replacement.
Detailed description
This study is designed as a multi-center, nonrandomized, uncontrolled, unblinded, prospective clinical outcomes investigation to evaluate the short, mid and long term performance of the PyroTITAN™ HRA Shoulder prosthesis humeral replacement. The PyroTITAN™ HRA Shoulder prosthesis device configuration will include humeral resurfacing CAP without cement. Patients will be selected for recruitment into the study based upon the normally accepted criteria for primary shoulder resurfacing arthroplasty. The investigation will be conducted by up to 10 International surgeons experienced in HRA. 387 subjects with PyroTITAN™ HRA Shoulder prosthesis arthroplasties will be implanted and followed for 10 years.

Participant flow
Recruitment details
Overall, 156 participants were enrolled to the study at five (5) sites.
Pre-assignment details
The Full Analysis Set (FAS) population includes 10 participants that received the TITAN device and 146 participants that received the PyroTITAN device. The TITAN device was renamed PyroTITAN by the previous sponsor (i.e., the same device). All participants were enrolled the same based on the eligibility criteria, so all participants are combined under the same primary cohort.
