Post Market Clinical Follow-up (PMCF) Study of the A.L.P.S. Proximal Humerus Plating System

The A.L.P.S. Proximal Humerus Plating System was developed to provide another surgical option for proximal humerus fracture fixation. The aim of the A.L.P.S. Proximal Humerus Plating System is to provide increased fracture stability while simultaneously increasing range of motion and decreasing the likelihood of screw perforation.

A minimum of 7 and maximum of 10 sites globally will be involved in this study. This number of clinical sites will allow for a better generalization of study data as well as allow for consistency to be developed across multiple regions. 135 implants will be included into the study. Each site will be allowed to enroll 27 humeri. Enrollment is competitive. All potential study subjects will be required to participate in the Informed Consent process.

• Patient must be able and willing to complete the protocol required follow-up.
• Patient must have a signed Institutional Review Board/Ethics Committee approved informed consent.
