Abstract Introduction Bilateral acute proximal humerus fractures are rare. There are no data available about these bilateral injuries. The aim of the study was to analyse bilateral proximal humerus fractures retrospectively in terms of incidence, complications and revisions. Methods All bilateral proximal humerus fractures were evaluated retrospectively using the institutionʼs database, with the focus on cause of the injury, fracture severity and the clinical course compared to published information on monolateral proximal humerus fractures. Bilateral posterior dislocation fractures were excluded, because these fractures are a separate entity. Results Between 2005 and 2016, n = 17 patients were primarily treated within our hospital for an acute proximal humerus fracture on both sides (n = 12 female, n = 5 male, average age: 68 years; overall 34 proximal humerus fractures). The general trauma mechanism was a fall on both arms (82% [18% polytrauma]). There were 65% displaced 3-/4-part proximal humerus fractures. Angle-stable plate osteosynthesis was performed predominantly (64%), followed by fracture prosthesis (18%; tension wiring: 3%; non-operatively: 15%). Overall, n = 10 patients (59%) or n = 18 (53%) proximal humerus fractures developed a complication, primarily with loss of reduction or implant loosening (44%). In n = 14 (78%) of the complications further operations were necessary. Alcohol abuse was increasingly found in 29% of the cases within the bilateral patient cohort compared to patients with monolateral fractures. Conclusion Bilateral proximal humerus fractures are mainly associated with comminuted displaced fractures and a higher complication rate in comparison to monolateral fractures after surgical treatment.

Purpose: This biomechanical study investigates the optimal number of proximal screws for stable fixation of a 2-part proximal humerus fracture model with a locking plate. Methods: Twenty-four proximal humerus fracture models were included in the study. An unstable 2-part fracture was created and fixed by a locking plate. Cyclic loading and load-to-failure tests were used for the following 4 groups based on the number of screws used: 4-screw, 6-screw, 7-screw, and 9-screw groups. Interfragmentary gaps were measured following cyclic loading and compared. Consequently, the load to failure, maximum displacement, stiffness, and mode of failure at failure point were compared. Results: The interfragmentary gaps for the 4-screw, 6-screw, 7-screw, and 9-screw groups were significantly reduced by 0.24 ± 0.09 mm, 0.08 ± 0.06 mm, 0.05 ± 0.01 mm, and 0.03 ± 0.01 mm following 1000 cyclic loading, respectively. The loads to failure were significantly different between the groups with the 7-screw group showing the highest load to failure. The stiffness of the 7-screw group was superior compared with the 6-screw, 9-screw, and 4-screw groups. The maximum displacement before failure showed a significant difference between the comparative groups with the 4-screw group having the lowest value. The 7-screw group had the least structural failure rate (33.3%). Conclusion: At least 7 screws would be optimal for proximal fragment fixation of proximal humerus fractures with medial comminution to minimize secondary varus collapse or fixation failure. Level of Evidence: Basic science study.
