RESUMO
[Objective]To introduce the technique important points of intramedullary fixation with bone cement add the plate fixation for treated the unstable proximal humeral fractures in elderly patients,and proceed the analysis to the principle of bone cement fix.[Method]Ten cases of the unstable proximal humeral fractures were treated with open reduction,intramedullary fixation with bone cement first,then fix with the plate.Three days after operation functional trainings were began.The radiographic outcome and shoulder joint functions were observed postoperatively at 1 month,3 months,6 months and 12 months.[Result]The results were excellent in 5 cases,good in 4 cases,fair in 1 case according to the JOA function standard.The rate of excellent and good clinical results was 90%.Radiography showed that the fractures dissects to reply in 7 patients,fractures still had 3～5 mm moving in 3 cases.All plates were fixed dependable,with no loosening.All fractures had bone fusion.[Conclusion]The intramedullary fixation with bone cement add fixation with plate for the unstable proximal humeral fractures in the elderly can proceed the functional training of the earlier period,acquire the satisfactory function instauration.
