[Abstract] Objective: To investigate the clinical efficacy of bone cement reinforced Locking plate in the treatment of proximal humerus fractures in the elderly.Methods: From January 2017 to January 2018, 63 patients with proximal humerus fracture who received surgical treatment in our hospital，according to whether or not bone cement is used,were divided into the enhanced group (32 cases) and the non-enhanced group (31 cases) .The perioperative period, follow-up and imaging data of the two groups were compared.Results: There were no statistically significant differences in length of hospital stay and intraoperative blood loss between the two groups （P>0.05）;The operation time of the enhanced group was slightly longer than that of the non-enhanced group（P<0.05）;VAS score 3 months after operation in the enhancement group was lower than that in the non-enhancement group（P<0.05）.At the last follow-up, fractures healed in both groups, and the fracture healing time was significantly shorter in the enhanced group than in the non-enhanced group（P<0.05）;Constant Murley scores were significantly higher in the enhanced group 3 months and 12 months after surgery than in the unenhanced group （P<0.05）;There was no significant difference in the neck dry Angle between the two groups immediately after the operation and at the last follow-up （P> 0.05）, but no enhancement group two time point Angle loss was significant（P<0.05）;However, there was no statistically significant difference between the two time points in the enhancement group （P> 0.05）.In the non-enhanced group, 2 cases of humeral head varus collapse and 3 cases of screw puncture occurred after surgery. In the enhanced group, 1 case of humeral head necrosis occurred without other complications.Conclusion: For the treatment of proximal humerus fractures in the elderly, the use of bone cement reinforced plate screw neck dry Angle loss is less, shoulder joint function recovery is better, fracture healing time is shorter and the incidence of complications is lower.
