This study evaluates biomechanical and clinical outcomes of intramedullary grafts alongside locked plating for unstable proximal humerus fractures, highlighting AVN risks.
Key Points
Intramedullary grafting significantly enhances axial stiffness and reduces varus deformation in unstable proximal humerus fractures.
Clinical results after a mean follow-up of 28.5 months show functional outcomes with a Constant-Murley Score of 73.4.
Patients with anatomical reduction had better outcomes, and humeral head avascular necrosis was the most common complication, occurring in 13 patients.
Biomechanical testing indicated that osteoporosis did not significantly impact stability or clinical results in the contexts studied.
