ABSTRACT

Background: Open reduction and plate fixation are the main surgical treatment methods for proximal humeral fracture. However, it is difficult to avoid iatrogenic deltoid insertion injuries while ensuring a proper plate position. We aimed to compare the deltoid muscle volume in treating proximal humerus fractures using the locking compression plate (LCP) and intramedullary (IM) nail fixation methods. Methods: Fifty-two consecutive patients who underwent surgical fixation for proximal humerus fractures were included in the present study. The participants were divided into two groups: the LCP fixation group and the straight IM nail fixation group. Results: No statistically significant differences were detected in the clinical outcomes between these groups. In the 12th week postoperatively, the union rate was much higher in the IM nail group (87.5%) than that in the LCP group (78.5%; p = 0.011). The deltoid volume ratio (%) was significantly higher in the IM nail group (97.5%) than in the LCP group (91.2%; p = 0.003). Conclusion: When treating proximal humerus fractures, straight IM nail fixation revealed convincing outcomes; thus, it could be a useful treatment option for early bony union and to avoid iatrogenic deltoid insertion injuries compared to LCP fixation.

Level of evidence: Level III, retrospective study.
