Abstract

The locking plate is used for osteoporotic long bone fracture because of the ability to affect a lock between the plate and locking screws that prevents reduction loss, angular deformity and axial deformity. However, it has been reported that locked plating can increase the periprosthetic fracture risk in osteoporotic bone compared with conventional plating. We report 3 cases of periprosthetic fracture after the use of locked plating in osteoporotic long bone fracture and a review of the relevant literatures.

Figure

  Figure 1 (A) The radiograph of a 83-year-old female's humerus showed fracture of the shaft. (B) The post-operative anteroposterior and lateral radiographs showed acceptable reduction with locked plating. (C) The follow-up radiograph 11 weeks after operation showed callus formation around the fracture site. (D) The follow-up radiograph 12 months after operation showed periprosthetic fracture around the most proximal locking screw.

• 

  Figure 2 (A) The radiograph of a 68 year-old female showed nonunion of the femur subtrochanteric fracture. (B) The post-operative anteroposterior and lateral radiographs showed acceptable reduction with locked plating and bone grafting. (C) The follow-up radiograph 12 months after 2nd operation showed periprosthetic fracture around the most distal locking screw.

• 

  Figure 3 (A) The radiograph of a 73-year-old female showed a fracture of the femur shaft. (B) The post-operative radiographs showed acceptable reduction with locked plating. (C) The follow-up anteroposterior and lateral radiographs 16 weeks after operation showed callus formation around the fracture site. (D) The follow-up radiograph 5 months after the operation showed a periprosthetic fracture around the most proximal locking screw.
