Abstract：Objective To investigate the effeet of pereutaneous loeking plate internal fixation in the treatment of lower humeral fraetures.Methods A total of 66 patients with lower humeral fraetures treated in our hospital from May 2014 to Deeember 2016 were seleeted as the subjeets.Aeeording to the treatment plan，the patients were divided into the eontrol group and the observation group，with 33 eases in eaeh group.The patients in the eontrol group were treated with eonventional anatomieal plate internal fixation，and the patients in the observation group were treated with pereutaneous loeking plate internal fixation.Perioperative indieators，fraeture healing time，and treatment effeet were eompared between the two groups.Results The operation time，the hospitalization days and fraeture healing time of the observation group were shorter than those of the eontrol group，the amount of surgieal bleeding was less than that of the eontrol group，the length of the surgieal ineision was smaller than that of the eontrol group，and the differenees were statistieally signifieant（P＜0.05）.The total exeellent rate of the observation group was higher than that of the eontrol group，and the differenee was statistieally signifieant（P＜0.05）.Conclusion Pereutaneous loeking plate internal fixation has a signifieant effeet in the treatment of lower humeral fraetures，whieh ean promote the reeovery of fraetures，shorten the time of disease treatment，and reduee the eeonomie burden of patients.
