ABSTRACT
Objective To compare the clinical effect of Multiloc nailing and Philos locking plate for treating proximal humerus fracture.Methods A retrospective analysis of 34 surgery treated proximal humeral fractures patients in Department of Orthopedics,Beijing Haidian Hospital and Department of Orthopedics,Beijing Chaoyang Hospital,Capital Medical University from January 2015 to June 2016,in which 3 cases of high-energy injury and multiple fractures andonecase of humerus head replacement and onecase of non-surgical treatment were excluded.Finally,29 patients were included and clinical followed up to 12 months after surgery.The 29 paients were divided into the locking plate group (n =13) and intramedullary nail group (n =16),The operative time,volume of intraoperative blood loss,preoperative to postoperative 24 patients were compared between the locking plate group and intramedullary nail group underwent open reduction and internal fixation with philos locking plate hemoglobin changes,24 h postoperative visual analogue scale and 3,6,12 months postoperative Constant-Murley shoulder function score.SPSS13.0 statistical software was used to analyze the data.Measurement data were expressed as ((x) ± s).Comparison of groups used independent samples t test,repeated measurement data used repeated measures analysis of variance.Results The age of the locking plate group was (65.7 ± 9.3) years,and the age of the intramedullary nailing group was (65.6 ± 11.1) years.In the locking plate group,the operation time was (150 ± 17) minutes,the intraoperative blood volume was (300 ± 53) ml,the change of blood pigment between before surgery to 24 hours after surgery was (26 ± 8) mg/L,and the vision algetic standard of 24 hours after surgery was (3.4 ± 0.8) scores.In intramedullary nailing group,the operation time was (119 ± 13) minutes,the intraoperative blood volume was (130 ± 25) ml,and the change of blood pigment between before surgery to 24 hours after surgery was (11 ± 5) g/L,the vision algetic standard of 24 hours after surgery was (2.3 ± 0.5) scores.No serious postoperative complications occurred in either group,including infection,internal fixationfailure,and humeral head necrosis.In locking plate group,for the Constant-Murley shoulder joint function score,3 months after surgery was (76.0 ± 11.6) scores,6 months was (78.0 ± 13.4) scores,12 months was (88.0 ± 12.1) score.In intramedullary nailing group 3 months was (85.0 ± 9.7) scores,6 months was (87.0 ± 8.9) scores,12 months was (89.0 ± 10.3) scores.There were no statistical difference between the two groups at incidence of serious complications after surgery,postoperative 12 months Constant-Murley shoulder joint function score.Muhiloc intramedullary nailing group was better than Philos locking plate group in the operation time,the intraoperative blood volume,etc.Conclusion Multiloc intramedullary nail is an effective method for treating proximal humerus fracture,and it has the advantages of less surgical injury and early postoperativesatisfactory than the locking plate.
