Effects of Plate-Bone Contact on Bridge Plate Fracture Fixation Biomechanics: Computational, Experimental, and Analytical Modeling.

ABSTRACT: Bridge plating is commonly used for internal fixation of comminuted fractures. The inner working length between screws has been established as a key parameter controlling postoperative biomechanical stability. However, plate-bone contact may affect these biomechanics in complex ways, and the offset between the plate and bone is variable across surgeries. The objective of this study was to examine the effects of construct and loading parameters on interfragmentary motion and maximum plate stress of bridge plating constructs. Finite element models were developed with variations in inner working length, plate-bone offset, fracture gap size, and loading type and magnitudes. Experiments with synthetic bones were conducted in parallel to support model credibility. Analytical models were also dev
