Randomized Controlled Trial Comparative Study
Are polyaxially locked screws advantageous in the plate osteosynthesis of proximal humeral fractures in the elderly? A prospective randomized clinical observational study.
To evaluate the results of plate osteosynthesis using either polyaxial or nonpolyaxially locked screw-plate systems in proximal humeral fractures in the elderly. ⋯ Both the functional outcomes and the rate of complications after polyaxial locked plate osteosynthesis of proximal humeral fractures in elderly patients were comparable to those treated with nonpolyaxial implants. Despite the theoretical advantages of polyaxial locked plating in proximal humerus fractures, this study could not show a verifiable clinical advantage of these plates.
