Clinical effects of locking proximal humerus plate for humeral proximal fractures in elderly patients / 中华老年医学杂志

ABSTRACT

Objective To discuss the clinical effects of locking proximal humerus plate (LPHP)for humeral proximal fractures in elderly patients.Methods A total of 84 elderly patients with humeral proximal fractures were retrospectively analyzed.Patients were randomly divided into LPHP group and control group (n=42,each group).Patients in LPHP group were treated with open reduction and internal fixation using LPHP.Patients in control group were treated with open reduction and Kirschner wire fixation.All patients were followed up for 1 year and the shoulder joint function was evaluated.Results There were no significant differences in bleeding volume and the wound healing time between LPHP group and control group [(189.2±27.5) ml vs.(177.6±28.2) ml,(102.3±6.2) days vs.(99.9±6.8) days,t=1.78,1.33,P=0.079,0.105,respectively].One year after the follow-up,there were 22 cases (52.4％,22/42) with excellent clinical evaluation,18 cases (42.9％,18/42) with good clinical evaluation and 2 cases (4.8％,2/42) with poor clinical evaluation in LPHP group,and 15 cases (35.7％,15/42) with excellent clinical evaluation,22 cases (52.4％,22/42) with good clinical evaluation,and 5 cases (11.9％,5/42) with poor clinical evaluation in control group.There was a significant difference in the evaluation rate of excellent and good clinical efficacy between in LPHP group and in control group (95.2 ％ vs.88.1 ％,x2 =3.18,P 0.028).Conclusions The internal fixation using LPHP has a good clinical effect in elderly patients with humeral proximal fractures,and it can well improve the recovery of shoulder joint function.
