Abstract
- PURPOSE
To evaluate the conformity of the anatomically pre-shaped LCP-PT to the tibias of the Korean adult and to identify radiological guidelines to assist intraoperative assessment of correct alignment.
MATERIALS AND METHODS
30 adult femur obtained from the Korean adult cadaver were used. A nine or eleven-hole LCP-DF was applied to the lateral surface of the tibia according to the contour. Then the distance from the inner surface of the plate to the lateral condyle was measured at the sites of mismatch. The angle between the most proximal screw and the articular surface was measured with the image intensifier.
RESULTS
The LCP-PT showed good conformity to the tibia in general. The distance from the inner surface of the plate to the lateral condyle was 3.5mm in average (range 0~9). The angle between the most proximal locking screw and the joint line was 1.16 degrees in average (range 0~7 degree).
CONCLUSION
The LCP-PT showed good conformity to the tibia in general. Malposition of the most proximal screw which is not paralleling to the joint line may herald a coronal plane malalignment.

PDF - PURPOSE
To evaluate the conformity of the anatomically pre-shaped LCP-DF to the femurs of the Korean adult.
MATERIALS AND METHODS
67 adult femur obtained from the Korean adult cadaver were used. An eleven-hole LCP-DF was applied to the lateral surface of the distal femur according to the contour. Then the distance from the inner surface of the plate to the cortex was measured at the sites of mismatch. The angle between the distal most screw and the articular surface was measured.
RESULTS
Mismatch was found at the level of proximal 4~5 holes of the plate with an average distance of 9.58 mm (0~18) at the tip of the plate. Otherwise, the overall conformity of the LCP-DF was excellent. The distal most screws are positioned such that the joint line is 3 degrees of valgus to this screw in average (range 0~18).
CONCLUSION
It may be necessary to consider to bend the plate in case of mismatch at the tip especially for the plate longer than 9-hole plate. The angular relation between the distal most screw and the joint line can assist the judgement for the coronal plane alignment. -
