Effect of Biotype Plus Stem Hemiarthroplasty on HHS and Complications in Elderly Patients with Intertrochanteric Fractures
Objective:To investigate the effect of biotype plus stem hemiarthroplasty on Harris hip score(HHS)and complications in elderly patients with intertrochanteric fracture.Method:A total of 94 elderly patients with intertrochanteric fractures admitted to Jingdezhen First People's Hospital from January 2022 to January 2023 were selected and randomly divided into two groups using a random number table method,with 47 cases in each group.The control group underwent cemented stem half hip arthroplasty,and the observation group underwent biotype plus stem hemiarthroplasty.The perioperative indicators(operation time,total blood loss,hospital stay,standing time on the following day,postoperative drainage rate),HHS,bone mineral density,and complications were compared between the two groups.Result:The operation time and fracture healing time of the observation group were shorter than those of the control group,and the standing time of the patients on the second day after operation was earlier than that of the control group,the total blood loss and postoperative drainage volume in the observation group were higher than those in the control group,the differences were statistically significant(P<0.05).There were statistically significant differences in HHS time point,intergroup and interaction between the two groups(P<0.05);there was no significant difference in preoperative HHS between the two groups(P>0.05);HHS in the observation group were higher than those in the control group at all time points after surgery(P<0.05);both groups were higher than those before surgery at all time points(P<0.05);3 months after surgery were higher than 6 weeks after surgery,the differences were statistically significant(P<0.05);6 months after surgery were higher than 3 months after surgery,the differences were statistically significant(P<0.05).There were significant differences in bone mineral density between two groups at different time points and between groups(P<0.05);there was no statistical significance between the two groups before surgery(P>0.05),and the observation group were higher than those of the control group at all time points after surgery,with statistical significance(P<0.05),both groups were higher than those before surgery at all time points(P<0.05);3 months after surgery were higher than 6 weeks after surgery,the differences were statistically significant(P<0.05);6 months after surgery were higher than 3 months after surgery,the differences were statistically significant(P<0.05).The incidence of complications in the observation group was lower than that in the control group,the difference was statistically significant(P<0.05).Conclusion:Biotype plus stem hemiarthroplasty can shorten the operation time,promote the postoperative recovery,improve the hip function and bone density,and reduce the risk of complications.However,there are also many problems of blood loss and postoperative discharge.
