TFN Percutaneous Insertion Handle for Obese Patients
For soft-tissue clearance in very obese patients, the standard trochanteric fixation nail (TFN) insertion instruments may be too short, as the barrel of the standard insertion handle only measures 44 mm in length. Therefore, a longer barrel for the percutaneous insertion handle was designed with an increased length of 144 mm. The added length necessitates a longer mating connecting screw and a longer 5.0 mm hexagonal screwdriver to engage the TFN locking mechanism.
Because of its length a more proximal skin incision than typical is needed. By concentrating on a more proximal skin incision in the obese patient one might avoid the necessity to lengthen the skin incision and deep soft-tissue dissection with the existing jig.
This additional handle should not be used on a nonobese patient as the added length of the arm may impinge on the soft tissues making the insertion more difficult.
