A prospective study of fractures of the femoral shaft treated with a static, intramedullary, interlocking nail comparing one versus two distal screws

Abstract

In a nonrandomized prospective study, 178 comminuted or length unstable femur fractures were treated with a statically locked, slotted, titanium alloy interlocking nail. Patients were divided into two groups based on the number of distal interlocking screws that were used. The patients were followed up for an average of 17 months to determine if the use of a single distal screw provided adequate fracture stability without loss of fracture fixation.
