Treatment of Proximal Humerus Fractures: Comparison of Shoulder and Trauma Surgeons
Surgeons’ disagreement about ideal treatment for proximal humerus fractures (PHFs) may reflect a difference in training.
We conducted a study to compare treatment decision-making by experienced shoulder and trauma fellowship–trained surgeons. Two expert shoulder surgeons and 2 expert trauma surgeons reviewed 100 consecutive PHFs surgically treated at another institution. Using available imaging, the examiners assigned scores for agreement with treatment decisions and for ratings of reduction/arthroplasty placement, fixation method, and radiographic outcomes. The scores were evaluated for interobserver reliability using intraclass correlation coefficients.
Overall, these experienced surgeons agreed poorly with treatment decisions and fixation methods but agreed moderately on acceptable reductions/arthroplasty placement and final radiographic outcomes. Agreement on the final radiographic outcomes was more uniform and acceptable for both shoulder and trauma surgeons. Trauma surgeons agreed more with each other about treatment decisions than shoulder surgeons agreed with each other.
In this study, surgeon disagreement and an aging population highlight the need for better evidence regarding optimal treatment for PHFs in order to improve consensus.
Conclusion
The surgeons surveyed in this study did not agree on ideal treatment for PHFs but moderately agreed on quality of radiographic outcomes. These differences may reflect a difference in training. We conducted this study to compare experienced shoulder and trauma fellowship–trained surgeons’ treatment decision-making and ratings of radiographic outcomes of PHFs when presented with the same group of patients managed at 2 level I trauma centers. We hypothesized there would be little agreement on treatment decisions, better agreement on final radiographic outcome, and a difference between decision-making and ratings of radiographic outcomes between expert shoulder and trauma surgeons. Our results showed that surgeons do not agree on the best treatment for PHFs but radiographically recognize when an operative treatment has been performed well or poorly. Regarding treatment decisions, our results also showed that expert trauma surgeons may agree more with each other than shoulder surgeons agree with each other. These results support our hypothesis and the limited current literature. The overall disagreement among the surgeons in our study and an aging population that grows sicker each year highlight the need for better evidence for the optimal treatment of PHFs in order to improve consensus.
