Prevention and treatment of deep venous thrombosis in hip fracture patients / 中华创伤骨科杂志

ABSTRACT

Objective To analyze factors influencing the incidence of deep venous thrombosis (DVT) and discuss the prevention and treatment of DVT in hip fracture patients. Methods The present study enrolled 531 patients who received surgery between June, 2008 to June, 2010 for hip fractures. They were 242 men with a mean age of 56. 2 years and 289 women with a mean age of 65.2 years. There were 336 femoral neck fractures, 183 femoral intertrochanteric fractures, and 12 femoral subtrochanteric fractures. The associations between DVT incidence and fracture type, plasma D-Dimer, sex, age and preoperative duration of immobilization were statistically analyzed. Inferior yens cava filters were used for patients who suffered DVT while surgery was performed. Results The total incidence of DVT was 10. 4% in this series. DVT occurred in 21 cases of femoral neck fracture, 34 cases of femoral intertrochanteric fracture and 0 case of femoral subtrochanteric fracture. All DVT events happened before surgery. DVT incidence had no significant associations with age or sex (P =0. 347 and 0. 376, respectively), but did with plasma D-Dimer, fracture type and preoperative duration of immobilization (P = 0. 002, 0. 017 and 0. 037, respectively). All the 55 DVT patients underwent a successful surgery. Conclusions The DVT incidence in hip fracture patients may have no significant associations with age or sex, but may do with plasma D-Dimer, fracture type and preoperative duration of immobilization. Inferior vena cava filters can ensure a successful internal fixation of the fracture and an uneventful postoperative rehabilitation.
