ntroduction: The dynamic hip screw (DHS) is the standard implant for treatment of trochanteric fractures.
Trochanter Stabilizing Plate (TSP) is a modular extension of the DHS that is employed to stabilize the
greater trochanter and the lateral wall. This Prospective study was conducted to compare the results of
using of DHS alone versus DHS with stabilizing plate for treating unstable trochanteric fracture (AO
classification type A2). Methods: 167 patients were evaluated for eligibility; the criteria were not met by
12 patients, and 5 patients declined to participate in the study. The remaining patients were randomly
allocated into two equal groups (75 patients in each) group 1 using DHS alone and group 2 using DHS with
TSP. Clinical evaluation was done using Clinical Harris Hip Scoring System (Modified HHS). Radiological
evaluation was done by x-ray to assess; healing time, neck shaft angle measurement and shaft medialization.
Results: Tip Apex Distance (TAD), the position of lag screw, and bone quality revealed insignificant differences
between both groups. Postoperative healing was insignificantly different between both groups. Postoperative
Harris hip score and neck shaft angle were significantly higher in group 2 than in group 1 (P value< 0.001
and 0.007 respectively). Conclusion: DHS combined with stabilizing plates have better radiological and
functional outcomes for treating unstable trochanteric fractures (AO classification type A2).
