Key result
Post-operative greater tuberosity resorption or malreduction was associated with poor prognostic outcomes in patients with proximal humeral fractures treated operatively.
Why the study?
Post-operative resorption or malreduction of the greater tuberosity is an important factor contributing to poor functional outcomes in patients with proximal humerus fractures, but functional outcomes following operative fixation required evaluation.
Does post-operative greater tuberosity resorption or malreduction worsen functional outcomes in patients with proximal humerus fractures treated operatively?
Observational (n=94)

Does post-operative greater tuberosity resorption or malreduction worsen functional outcomes in patients with proximal humerus fractures treated operatively?
Post-operative greater tuberosity resorption or malreduction, exacerbated by obesity, is associated with poor functional outcomes following operative fixation of proximal humerus fractures.
Greater tuberosity issues after ORIF signal need for vigilant follow-up; leaves open whether technique modifications improve outcomes in complex proximal humerus fractures.
(1) Background: Proximal humerus fractures can be a debilitating condition if not properly treated. These fracture patterns are varied and differ in every patient. Functional outcomes may be determined by the integrity of the shoulder girdle involving the rotator cuff insertion. The post-operative resorption or malreduction of the greater tuberosity is an important factor contributing to the poor functional outcome of a patient. (2) Methods: A single-center retrospective comparative study was performed to evaluate the functional outcomes of patients undergoing operative fixation for this injury. A total of 387 consecutive cases treated operatively from 2019-2021 were included for analysis. (3) Results: 94 cases fulfilled our criteria for analysis. A matched-group comparison of 19 patients each was performed to compare demographics, post-operative fracture characteristics and functional outcomes. (4) Conclusions: The resorption or malreduction of the greater tuberosity contributes greatly to the prognostic outcome in patients treated with ORIF surgery. In our demographic study, obesity is another contributing factor affecting the parameters of post-operative reduction in proximal humerus fractures. Appropriate surgical planning and post-operative multidisciplinary care must be taken into consideration to attain a satisfactory prognostic outcome.

Lu et al. (2023) conducted an observational in Proximal humeral fractures (n=94). Post-operative greater tuberosity resorption or malreduction vs. No resorption or malreduction was evaluated on Functional outcomes. Post-operative greater tuberosity resorption or malreduction was associated with poor prognostic outcomes in patients with proximal humeral fractures treated operatively.
