Code:

NCT01354535

Conditions

Femur Fractures

Eligibility Criteria

Age: 18 - 70+

Healthy Volunteers: Not accepted

Interventions

Isolated Locked Compression Plate

Cable Plating and Strut Allograft with Cerclage Wiring

Study Details

Brief summary:

The purpose of this study is to compare two different but standard treatments for the fixation of Vancouver B1 periprosthetic. The investigators aim to compare open reduction internal fixation using a locked plating system versus plating and strut allograft with cerclage wiring to determine which treatment results in a faster return to function as measured by the TUG test at 6 weeks post-op.

Interventions and Outcome Measures

Arms

active comparator: Cable plating with strut

The plate will be placed laterally with the allograft strut placed on the anterior cortex. Screw fixation will be used distal to the stem and cables and screws will be used proximal to the stem tip. Cerclage cables or wires will be used to secure the strut.

active comparator: isolated plating

A lateral thigh incision will be used to expose the fracture site. Surgeons will attempt to minimize devascularization of the bone by meticulous dissection and indirect reduction techniques. An appropriate sized plate will be applied to the lateral aspect of the femur. Fracture reduction will be achieved with the use of intra-operative fluoroscopy and the plate will be secured with locking screws.
