title: Removal of the deeply inserted proximal interlocking screw in the greater trochanter after femoral nailing.
abstract: Removal of the proximal interlocking screw (PIS), especially one that is deeply inserted in the greater trochanter or covered by heterotopic ossification, is troublesome and requires considerable effort because the search for its head usually requires removing bone from around the insertion site. We introduce a simple tip to remove this complicated PIS with the aid of a proximal drill guide, drill bit, and AO countersink.
