• PURPOSE
    • The cerclage passer instrument was introduced for aiding percutaneous reduction in spiral femur fractures, thereby overcoming the risk of devascularization of the fracture ends commonly associated with traditional open cerclage wiring techniques. This may, however, predispose to iatrogenic vascular injuries owing to the proximity of the vessels and several other factors. We report four cases with femoral artery (superficial and deep) injuries caused by the cerclage passer in proximal femur and distal femur shaft fractures and incidence of these injuries in our institution.
  • METHODS
    • Retrospective analysis of hospital records of femoral fractures from 2011 to 2015. All cases of femoral fractures and periprosthetic femoral fractures with cerclage wiring done using the standard or the Synthes® cerclage passer were included. Cases with wiring done for trochanteric fractures and other locations were excluded.
  • RESULTS
    • Incidence of vascular injuries due to the cerclage passer in proximal femur shaft fractures was 1.59%, whereas in distal femur shaft fractures it was 7.14%. There were two patients with a deep femoral artery (DFA) system injury and two with a superficial femoral artery (SFA) injury caused by the cerclage passer (Synthes) in two proximal femur shaft and two distal femur shaft fractures, respectively. End-to-end anastomosis for the SFA and ligation for DFA system injuries were used, with an uneventful postoperative period in all patients.
  • CONCLUSION
    • Caution and accuracy is imperative to avoid vascular injuries while using the cerclage passer in femur fractures, and strict vigilance is essential for early identification and prompt management.
