Two kinds of locking plate for treatment of proximal humerus fractures in the elderly / 中国组织工程研究

ABSTRACT

BACKGROUND:Proximal humeral internal locking system (PHILOS) and locking proximal humerus plate (LPHP) are both new types of internal fixation plates, and have satisfactory effects in the treatment of proximal humerus fractures. However, which is better? OBJECTIVE:To compare the short-term efficacy of PHILOS and LPHP in the treatment of elderly patients with proximal humeral fractures. METHODS:The fol ow-up data of 61 elderly patients with proximal humeral fractures were retrospectively analyzed. The patients were divided into PHILOS group (n=34) and LPHP group (n=27). According to the Neer system, there were two parts of fractures in seven cases, three parts of fractures in 11 cases, four parts of fractures in nine cases in LPHP group;there were two parts of fractures in nine cases, three parts of fractures in 14 cases, four parts of fractures in 11 cases in PHILOS group. The operation time, blood loss, and drainage volume were recorded. The time of fracture healing, functional recovery, and complications were observed. Statistical analysis was performed. RESULTS AND CONCLUSION:Al 61 patients were fol owed up for 12-36 months (mean 20.6 months). There was no statistical difference in operation time, blood loss, drainage volume, time of fracture healing, functional recovery and complications between the two groups (P>0.05). Both LPHP and PHILOS groups could obtain good effects in treatment of senile proximal humeral fractures. The excellent and good rate was respectively 81.5%and 82.4%in two groups. They have advantages of reliable fixation, few complications, and high satisfaction rate. Currently these locking plates have a high clinical value and can be considered as useful implants for ORIF of displaced and unstable proximal humeral fractures.
