Treatment of Unstable Trochanteric Fractures Using Dynamic Hip Screw Combined with Additional Buttress Plate.

We lveated 131 cases of unstable trochantric fracture in our hospital. Of these 131 cases, 64 were treated with dynamic hip screw (group A), and 67 were treated by dynamic hip screw combined with an additional buttress plate (group B).Telescoping of the screw more than 15mm occurred in 12.5% in group A, and 7.5% in group B. Anatomical reduction and stable fixation were achieved in group B. All patients could walk on average 2 weeks post-operatvely shortens the period requied for post-operative bed-rest.
