Outcome After Plate Osteosynthesis of Proximal Humerus Fractures Using Continous Passive Motioning Therapy

The investigators will conduct a prospective, monocentric study focusing on the rehabilitation process after surgical treatment of proximal humerus fractures. Patients treated with plate osteosynthesis and eligible to participate will be randomly assigend to either a regular rehabilitation protocol (immobilization and physiotherapy) or a rehabilitation protocol with the additional use of a continous passive motion device (immobilization, physiotherapy and CPM). After 6 and 12 weeks as well as 1 year in a follow-up examination functional (range of motion) and patient-reported outcome (Disabilities of Arm, Shoulder and Hand Score \[DASH\], Constant-Score, pain on visual analogue scale, subjective satisfaction) will be evaluated. Results will be compared towards possible differences and effect of CPM therapy. In addition demographic factors (age, sex, BMI, etc.) and complications will be analysed.
