Abstract Objective To study the effect of fibular allograft transplantation combined with locking plate on prevention of inversion and sag after comminuted proximal humerus fracture operation in the elderly. Methods Clinical data of 72 elderly patients with comminuted proximal humerus fractures admitted to Beijing Jishuitan Hospital from January 2015 to December 2018 were summarized. The patients were divided into two groups according to the operative methods: the plate group (41 cases) treated with locking plate alone, and the graft group (31 cases) treated with fibular allograft transplantation combined with locking plate. The operative time and intraoperative blood loss were compared between the two groups. The follow-up time, visual analogue scale (VAS) at last follow-up, University of California, Los Angeles (UCLA) shoulder function score and Constant shoulder score were compared between the two groups. The changes of neck-shaft angle and humeral head height were compared between the two groups after operation and the last follow-up. Results There were no significant differences in operative time, intraoperative blood loss, follow-up time and VAS at the last follow-up between the two groups (P > 0.05). UCLA shoulder function score and Constant shoulder score in the graft group were higher than those in the plate group at the last follow-up, with statistical significance (all P < 0.05). The neck-shaft angle and humeral head height in the last follow-up in both groups were lower than those after operation, and those in the graft group were higher than those in the plate group, with statistical significance (all P < 0.05). Conclusion Fibular allograft transplantation combined with locking plate in the treatment of comminuted proximal humerus fractures in elderly has a good effect of inversion and sag of the humerus head, and can improve the prognosis of patients.
