Abstract:Objective
To compare the efficacy between  two different methods of internal fixation  in the treatment of senile osteoporotic complicated fractures of  proximal humerus.  Methods
125 senile patients with osteoporotic complicated fracture were divided into two groups to receive different internal fixation and surgical treatment （Kirschner needle or traditional internal fixation was Group A, internal fixation of locking compression plate was Group B, and there were two respective subsections). There were 42 patients with Ⅲ-part fracture according to Neer classification receiving Kirschner needle or traditional internal fixation(Group A1), 29 patients with Ⅲ-part fracture receiving internal fixation of locking compression plate(Group B1). There were 19 patients with Ⅳ-part fracture receiving Kirschner needle or traditional internal fixation(Group A2), 35 patients with Ⅳ-part fracture receiving internal fixation of locking compression plate(Group B2).The patients were  followed up for 6 to 24 months (average 12.2 months).Neer score system was used to appraise therapeutic effect, and 80 points was defined as excellent and good. Results There were 29 cases exceeding or equaling to 80 points in Group A1, the excellent and good rate was 69.05%, while the patients in Group B1 were 26 and the excellent and good rate was 89.66% , there was significant difference between two groups (P<0.05). There were 8 patients exceeding or equaling to 80 points in Group A2, the excellent and good rate was 42.11%, while the patients in Group B2 were 25  and the excellent and good rate was 71.43%,there was significant difference between two groups (P<0.05). Conclusion   Compared with traditional fixation, locking compression plate has advantage in treatment of  senile osteoporotic complicated fractures of  proximal humerus
