Abstract:
BACKGROUND:Periprosthetic femoral fracture is a severe complication after total hip arthroplasty. More than 85% belongs to Vancouver B2 and B3 fractures, and the operation is difficult. OBJECTIVE:To explore the clinical effect of Cable-Ready fast system and biotype long-stem prosthesis and its effect on the recovery of joint function in patients with Vancouver B2 and B3 type periprosthetic femoral fractures after total hip arthroplasty. METHODS: A total of 60 patients receiving total hip arthroplasty suffered from Vancouver B2 and B3 type periprosthetic femoral fractures in the Huanggang Central Hospital from September 2011 to September 2012. They were equaly divided into control and observation groups according to different fixation methods. Patients in the control group were treated by ordinary steel wire cerclage fixation combined with uncemented long-stem prosthesis; those in the observation group were treated by Cable-Ready fast system combined with fast uncemented long-stem prosthesis. RESULTS AND CONCLUSION:The average operation time, the time of hospitalization and fracture healing time were shorter in the observation group than in the control group. Moreover, the intraoperative blood loss was less in the observation group than in the control group. After 1 year of folow-up, Harris hip score was higher in the observation group compared with pre-treatment (t=3.174 9,P=0.002 6), and significantly higher than the control group (t=2.479 8,P=0.015 4). The excelent and good rate of Harris hip score was significantly higher in the observation group than in the control group (χ2=11.294 5,P=0.002 6). The total incidence of complications was significantly lower in the observation group than in the control group (χ2=8.139 7,P=0.04 2). These data indicate that Cable-Ready fast system combined with uncemented long-stem prosthesis in the treatment of Vancouver B2 and B3 periprosthetic femoral fractures after total hip arthroplasty has smal injury, less postoperative complications and better recovery of hip function after operation.
