Clinical Trial Summary

This study is a multicenter, prospective, non-randomized, non-controlled post-market clinical follow-up study. The primary objective of this study is to confirm the safety and performance of the A.L.P.S. Proximal Humerus Plating System applied in proximal humerus fracture treatment.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Re-operation	Re--operation within the first year post-initial surgery due to screw perforation of the humeral head, secondary displacement or impingement to relieve pain and/or improve function.	1 year
Secondary	Clinical efficacy of the device is assessed using the American Shoulder and Elbow Surgeon Patient Questionnaire	Pain, function and activities of daily living are measured. The American Shoulder and Elbow Surgeon (ASES) scale is 0 to 100. 100 is the highest score and indicates the greatest function while 0 is the lowest score.	2 years
Secondary	Shoulder range of motion measurement	Shoulder range of motion is assessed in degrees of directional movement. This will be measured during a physical exam by the investigator. Values measured include active and passive range of motion.	2 years
Secondary	Clinical performance of the device is assessed using x-ray capture	X-ray capture will be used to analyze fracture healing	2 years
