Abstract Objective To compare the Singh index of patients with contra-lateral hip re-fractures and non-fractures after operation of intertrochanteric fractures and investigate the value of Singh index in patients with intertrochanteric fractures.Methods Records from 218 cases undergoing surgery for intertrochanteric fracture at our hospital from January 2014 to December 2016 were retrospectively reviewed，the patients were divided into a re-fracture group and no-re-fracture group according to presence or absence of re-fracture on the contra-lateral hip after operation.Singh index grading were compared between the two groups.Results a)All patients were followed up from 24 to 60 months with an average of 42.9 months，the incidence of contra-lateral hip re-fractures after intertrochanteric fractures was 5.2％，and the interval between the first fractures and the contralateral fractures was 11.5 months；b)The Singh index of the non-fracture group after intertrochanteric fracture was graded at an average of 4.0，whilein the re-fracture group itwas 3.5，P＝0.05.The difference between the two groups was statistically significant.The Singh index lower than grade 4 can be used as a threshold for predicting contra-lateral hip re-fractures after intertrochanteric fractures.c) The correlation index of Spearman about Singh index and BMD was 0.66，P＜0.001，which had a significant correlation.Conclusion The lower the Singh index of patients with intertrochanteric fractures，the more severe of the reduction in bone loss，and the incidence of contralateral hip fractures is higher (P＜0.05).The Singh index is a simple and effective method for assessing contralateral hip fracture after operation of intertrochanteric fractures.
