Abstract：Objective To compare the effect of artificial humeral head prosthesis replacement and locking plate in the treatment of complex proximal humeral fractures.Methods The clinical data of 32 patients with com-plex proximal humeral fractures admitted to Department of Orthopedics in Jiangbei People's Hospital from 2013 to 2016 were retrospectively analyzed.Among them,16 cases(replacement group)were treated with artificial humeral head prosthesis replacement,and 16 cases were treated with locking plate internal fixation(internal fixation group). The general operation condition,clinical efficacy,VAS score and Constant -Murley score at 4 weeks after operation were compared between the two groups.Results (1)There was no significant difference in operation time,amount of intraoperative bleeding and cost of one-off operation(P>0.05);(2)there was no significant difference in good rate of Neer score between the two groups(replacement group:75.00%;internal fixation group:81.25%)(P >0.05);(3)there was no significant difference in VAS between the two groups(replacement group:2.14 ±0.52;internal fixation group:2.37 ±0.61)(P>0.05);(4)there was no significant difference in Constant-Murley score between the two groups(replacement group:65.28 ±13.04;internal fixation group:61.44 ±11.62)(P>0.05). Conclusion There is no significant difference in operative time,intraoperative blood loss and operative cost be-tween artificial humeral head prosthesis replacement and locking plate in the treatment of complex proximal humeral fractures.The choice of the operation depends mainly on the indications ,complexity of the fracture and the general condition of the patients.
