Abstract
After internal fixation of the femoral trochanteric fracture using short femoral nail, shortening of fracture site induced lateral projection of the lag screw, thus developing a risk of decubitus. Removal of nail may therefore become necessary, but in patients whose condition is worsening, any additional operative invasion may pose a problem.
The Inter Blade Nail System (IBN, Nakashima Medical Co., Ltd., Japan) is a medullary nail for the femoral trochanteric fracture enabling shortening of the lag screw. Here we report two cases for which lag screw shortening was performed to avoid excessive telescoping after the operation.
The first patient was a 73-year-old woman who underwent the procedure 14 months after the operation. Lateral projection of the screw was reduced from 23mm to 12mm, and the operation time was 20 minutes. The other patient was a 93-year-old woman who underwent the procedure 15 months after the first operation. Projection of the screw was reduced from 27mm to 16mm, and the operation time was 15 minutes.
Both procedures were accomplished easily, and the implant useful was considered useful for these elderly patients who had a high risk of developing decubitus.
