Mechanics of Supplemental Drop Wire and Half-Pin Fixation Elements in Single Ring Circular External Fixator Constructs

Objective Evaluate the effects of supplemental fixation elements on the mechanical properties of a single ring circular fixator construct. Study Design In vitro mechanical testing. Sample population : Five construct configurations (six replicates of each configuration) were used to stabilize a 1.6 cm diameter Delrin rod bone model. Methods Constructs were assembled using 66 mm complete rings, 1.6 mm olive wires, and 3.2 mm diameter half‐pins....
