Objective. The objective of this study was to compare the clinical outcomes and complications between the locking compression plate (LCP) and LCP with fibular allograft in the treatment of patients with displaced proximal humerus fracture (PHF) in elderly people. Material and Methods. Between January 2010 and December 2013, a total of 97 elderly patients with displaced PHF were treated by LCP or LCP with fibular allograft, and finally 89 patients were included in our study. All the patients were divided into Group I (patients treated by LCP) and Group II (patients treated by LCP with fibular allograft). Function results were assessed by the disability of the arm, shoulder, and hand (DASH) score and Constant-Murley score (CMS), and complications were also recorded in each group. Results. The average follow-up was 35.2 months (range, 24-48 months) in Group I and 33.5 months (range, 24-48 months) in Group II. DASH in patients of Group I was significantly higher than that in patients in Group II and patients of Group I had CMS scores significantly lower than patients in Group II (P<0.05). The rates of varus malunion, screw perforation, and loss of reduction>5mm were significantly higher in Group I than in Group II (P<0.05). Conclusions. The present results showed that that patients treated by LCP with fibular allograft had a better functional outcome and a lower complication rate compared to patients treated by LCP alone. Suitable void filler in the proximal humerus for supporting the head fragment, medial cortical bone, and greater tuberosity might play a key role in reducing the incidence of the complications in elderly patients, especially with osteoporosis.
