Technique for Removal of Broken InterTAN Integrated Cephalomedullary Screw
View through CrossRef
Summary:
Pertrochanteric femoral fractures are routinely treated with cephalomedullary nailing, with good success. In the event of nonunion, implant fatigue failure may occur. The Trigen InterTAN system (Smith & Nephew, Memphis, TN) features 2 integrated cephalomedullary screws for improved rotational stability of the proximal segment. The inferior compression screw prevents rotation of the larger, superior lag screw. In the event of inferior screw breakage, the retained portion will prevent the integrated lag screw from being rotated to permit extraction. We present a case of a broken nail as well as a broken integrated screw, and describe a technique for successful implant removal.
