Comments on the “Effect of an orthogonal locking plate and primary plate working length on construct stiffness and plate strain in an in vitro fracture-gap model”

Preview

Among other tests, the authors of this paper studied the effect of working length on plate strain between the two innermost plate holes (area of interest) of a single LCP implant.1 In Table 3, the authors report no significant difference in the strain between SWL and MWL, but the strain in LWL was significantly higher than that of both SWL and MWL. Nevertheless, in the abstract, the authors state that “single plate construct strain was significantly, incrementally, higher as working length was extended.” This statement gives the wrong impression as it creates a pattern of a direct relationship between plate strain and working length, which does not reflect the findings.
