ARROW Prime – Dual-Platform Shoulder Arthroplasty

The ARROW shoulder system has been designed to perfectly fit any size humerus. This allows it to be used for complex, post-fracture shoulder reconstructions, and total joint replacements.

Concept and benefits

The ARROW PRIME Dual-Platform Shoulder system was the first universal system for shoulder arthroplasty. It allows surgeons to implant reverse or anatomical prostheses using the same set of instruments.

Thanks to the universal instrument set, the surgeon is able to decide intraoperatively whether they will perform a hemi, total or reverse shoulder arthroplasty. There is no need for preselection.

Furthermore, the ARROW PRIME Dual-Platform Shoulder system allows for the conversion of a hemi prosthesis into a total shoulder and/or to a reverse shoulder without switching out the stem and causing more trauma to the patient. This saves surgical time for both the surgeon and the patient.

The unique, simple instrumentation set, universal stem, and conversion implants for both types of prostheses make the ARROW PRIME Dual-Platform Shoulder system easy, reproducible, and highly beneficial for both patient and surgeon.
