Introduction: The purpose of the article was to evaluate the results of treatment with long-contoured humerus proximal locking anatomic plates applied with open reduction and internal fixation to elderly patients with traumatic proximal humerus fractures with distal metaphyseal or diaphyseal extension. Material and Method: In our department a total of 22 patients were managed for humerus proximal fracture with metaphyseal or diaphyseal extension between 2013-2016. The patients comprised 17 (77%) females and 5 (23%) males with a mean age of 65 years (range: 60-76 years). All patients were managed with long-contoured humerus proximal locking anatomic plate using deltopectoral approach. At the final follow-up examination, patients were evaluated for clinical outcome using the Oxford Shoulder Score and Disabilities of theArm Shoulder and Hand Score. Assessed for residual pain, time to union and any complications retrospectively. Results: The mean follow-up period was 18 months (range: 16-56). Mean time to union was 14.2 weeks (range: 12-20 weeks). At the final follow-up examination, the mean VAS score was as 1.8, the mean DASH score was 18.3 (95% CI=13.3-41.7), and the mean OSS score was 38 (95% CI=27.3-44.9) (Table 2). In the evaluation of joint ROM, mean shoulder abduction was determined as mean 146.3° (range, 80°-170°), and shoulder flexion 143.6° (range: 80°-170°). Conclusion: In the current study, successful results were shown in osteoporotic bone with the application of a locking plate with open reduction in fractures involving the metadiaphyseal area of the proximal humerus following low-energy trauma in patients aged over 60 years.
