Figures and Tables
Fig. 1
Because the plate is not compressed on the bone, the blood supply will be preserved in LCP (A) than LC-DCP (B).
Fig. 2
(A) Conical thread allows a secure fixation of the locking head screw.
(B) Dynamic compression can be achieved by eccentric insertion of standard screw at this hole.
Fig. 3
(A) Once the metaphyseal fragment has been fixed with locking head screws, this portion can be compressed to the shaft with standard screws at compression hole.
(B) Arrangement of the combination holes.
Fig. 4
Plate span ratio and plate screw density in bridge plate. Plate span ratio is the quotient of plate length and overall fracture length. Plate screw density is the quotient formed by the number of screws inserted and number of the plate holes (From Gautier E, Sommer C: Injury 34(Suppl 2), 2003).

(A) In normal bone, working length of monocortical screw is sufficient enough to withstand rotational displacement.
(B) In osteoporotic bone, working length of monocortical screw is insufficient due to thin cortex and under torque the bone thread soon will wear out and secondary displacement and instability will occur.
(C) In osteoporotic bone the bicortical screw is recommended because of the longer working length leading to a much higher torque resistance (From Gautier E, Sommer C: Injury 34(Suppl 2), 2003).
