Abstract：Objective To explore the clinical efficacy between two types of artificial femoral head replace -ment in the treatment of elderly patients with Garden Ⅲ and Ⅳ femoral neck fractures .Methods A retrospective analysis of 78 elderly patients with femoral neck Garden Ⅲ and Ⅳ fractures admitted to Lianyungang Hospital of Traditional Chinese Medicine from Jan .2011 to Jun.2016 was performed .Forty patients were treated with cemen-ted artificial femoral head replacement ( bone cement group ) and 38 patients were treated with biological artificial femoral head replacement ( biotype group ) .The intraoperative and postoperative indexes and hip function recovery were compared between the two groups .Results The operation time of the biotype group was shorter than that of the bone cement group (P<0.05).The intraoperative blood loss,postoperative drainage volume,activity time,rehabilita-tion training time,postoperative weight bearing time ,blood transfusion rate and transfusion volume in the biotype group were significantly higher or later than those in the bone cement group (P<0.05).At 3 months after operation,the Harris score of the biotype group was lower than that of the bone cement group ( P<0.05) .At 6 months after opera-tion,there was no significant difference in Harris score between the two groups ( P>0.05).The Harris scores at 6 months after operation in both groups were significantly different from those at 3 months after operation(P<0.05).At 6 months after operation ,the excellent and good rate of hip function was 95.00%in the cemented group and 89.47%in the biotype group,and the difference was not statistically significant (P>0.05).Conclusion Both bone cement and biological artificial femoral head replacement have good effect on femoral neck fractures of Garden type Ⅲ and type Ⅳ,but cemented artificial femoral head is beneficial to early rehabilitation training ,and its function recovery is earlier.
