| Summary: | Background:
Multiple options exist for fulcrums in balanced cable bone segment transport (BC-BST) procedures, but there is no consensus among orthopedic surgeons on best practices. Aims and Objectives: This study investigates the mechanical differences between a variety of fulcrums used to perform this reconstructive technique.
Materials and Methods:
A custom testing rig was built to determine the tension-modifying effects of different fulcrums on the BC-BST system.
Results:
The stiffness of the system was inversely related to the displacement of the spring, and the least stiff system occurred in fulcrums without threads and of larger diameter.
Conclusion:
These observed differences suggest that the diameter and type of fulcrum used impact the BC-BST system and there may be an opportunity for greater personalization of the pull tension. |
