Abstract:

BACKGROUND: Lower extremity deep venous thrombosis is commonly seen after hip arthroplasty. The time of thrombosis after arthroplasty in senile patients with osteoporotic femoral neck fractures is little reported.

OBJECTIVE: To investigate the time of perioperative lower extremity deep venous thrombosis in senile patients with osteoporotic femoral neck fractures undergoing hip arthroplasty.
METHODS: The data of 178 patients with femoral neck fractures undergoing hip arthroplasty were analyzed, and were then allocated to anticoagulant and non-anticoagulant groups according to the preoperative use of low-molecular-weight heparins or not. Doppler ultrasonography of both lower extremity arteries was conducted at 1, 3, 5 and 5-7 days after injury, and 2, 5, 7 and 14 days postoperatively to monitor the lower extremity deep venous thrombosis, and the number and incidence of thrombosis in the two groups were recorded at different time points. The time of thrombosis occurred frequently after injury and surgery was determined through drawing the frequency distribution table and line chart.
RESULTS AND CONCLUSION: (1) The incidence of thrombosis showed significant difference between anticoagulant (n=6, 8%) and non-anticoagulant (n=22, 21%)) groups (P < 0.05). (2) Thrombosis frequently occurred at 3 days after injury and 1 day postoperatively. (3) These results suggest that the thrombosis in patients with femoral neck fractures frequently occurs at 1-3 days after injury and 1 day after replacement. Additionally, active prevention measures after injury can significantly reduce the incidence of lower extremity venous thrombosis.
