Implant-induced trabecular damage in cadaveric femoral necks.
After insertion of Newman's pins, Smith-Petersen nails and compression hip screws into human cadaveric proximal femora, the area of trabecular damage was measured. The nail and hip screw caused four times the area of damage seen with Newman's pin. The Smith Petersen nail caused significant peripheral damage which was undetectable radiographically.
