Locking Compression Plate For Hypertrophia Bone Nonunion Following Intramedullary Nailing

Objective:Intramedullary nailing is widely used in the treatment of long bone fractures. But some patients suffered nonunion after using intramedullary nailing. This paper was to investigate the methods and effects of locking compression plate (LCP) in the treatment of hypertrophia bone nonunion after intramedullary nailing.Methods:A total of6patients with hypertrophia bone nonunion after intramedullary nailing were treated by LCP, including4males and2females aged23-67(mean47).Three cases occurred in the shaft of femur,2in the tibia and1in the subtrochanteric femur. The average time from injury to LCP treatment was12.2months. The two ends of LCP were fixed with3or4one-side locking screws. All the6cases received iliac bone graft.Results:6patients were followed up for5to20months (mean9months). X-ray imaging showed bone callus at the broken ends of the fracture at3-7(mean4.5) months after surgery without complications such as infection and breaking or loosening of the LCPs.Conclusion:LCP can be used for the treatment of hypertrophia bone nonunion after intramedullary nailing for its convenience, minimally invasive and curative effect.
