Proximal humerus fractures (PHF) constitute the majority of the most common osteoporotic fractures. Bone density measurements can affect treatment methods and outcomes.

This study was aimed to investigate the effect of osteoporosis values, measured from direct radiographs, on fracture type, surgical outcomes.

248 patients over 50 years of age who presented to Mersin City Hospital between 2017 and 2020 with proximal humeral fractures were retrospectively evaluated.

The age and gender of the patients and the fracture types were evaluated according to the AO classification system from the direct radiographs obtained at the time of admission were recorded.

The Tingart cortical thickness and deltoid tuberosity index (DTI) measurements were used to assess osteoporosis status in all patients.

Postoperative and follow-up radiographs of 45 patients, treated with fixed-angle proximal humeral locking plate, were evaluated for radiographic results and their correlations with osteoporosis measurements were examined.
