Comments on the Article "The Effect of Positive Medial Cortical Support in Reduction of Pertrochanteric Fractures with Posteromedial Wall Defect Using a Dynamic Hip Screw": To the Editor

The utility of additional fixations for sliding hip screws has been well demonstrated in the study entitled “Additional fixations for sliding hip screws in treating unstable pertrochanteric femoral fractures (AO type 31-A2): short-term clinical results.” 1) I have read with great interest the recent study, “The effect of positive medial cortical support in reduction of pertrochanteric fractures with posteromedial wall defect using a dynamic hip screw,” by Cho et al.2) While I appreciate citation of my paper in this article, I have some concerns as follows. First, reasoning from Table 3 of Ref. 2 and the total number of enrolled cases, I can conclude that all the cases were additionally fixed with either wire or trochanter stabilizing plate (TSP), or both: 26 cases were fixed with a wire alone; 72, with TSP alone; and 2, with both wire and TSP. Therefore, no use of wire for fragment fixation (n = 72) refers to cases with TSP alone and no use of TSP (n = 26) refers to cases with wire alone. KCI Citation Count: 0
