On line, at this point, the steel nail head (33) that will fix steel nail (3) one end is inserted from the first perforation (13) on side seam plate (1) outer wall
Enter, and pass through femur, until steel nail head (33) pass through main bone nail (2) outer wall on second perforation (21), complete side seam plate (1) and
The fixation of main bone nail (2)；
S2, positioning femur: positioning steel nail (4) being penetrated from the first positioning hole (14) on 1 outer wall of side seam plate, and passes through femur,
Until second location hole (22) of positioning steel nail (4) on main bone nail (2) outer wall, completion side seam plate (1) and main bone nail (2)
Positioning；
S3, insertion intramedullary nail (5): intramedullary nail (5) is penetrated from the first Intramedullary nailing hole (16), and passes through top plate (11) for marrow
In interior nail (5) insertion femur, the fixed effect of top plate (11) and femur is further strengthened by intramedullary nail (5), then by intramedullary nail
(5) it is penetrated from the second Intramedullary nailing hole (17), and passes through side seam plate (1) and intramedullary nail (5) are inserted into femur；
S4, titanium silk (6) are tightened: titanium silk (6) is penetrated from the side opening (15) of top plate (11) side, and ring-wound is in femur outer wall
One circle, so that titanium silk (6) is pierced by from symmetrical side opening (15), and titanium silk (6) is fitted on femur outer wall, at this time by titanium silk
(6) both ends are fixed.
