Broken screws after interlocking nailing of long bones are commonly seen in Orthopaedic practice. Removal of such screws can be difficult particularly the distal part which is often held within the bone. We describe a simple technique of using Steinman pin to aid removal of broken screws in a case of non-union fracture tibia with broken interlocking nail and screws. Steinman pin being easily available and the reproducible technique make it a useful aid for removal of broken interlocking screws.

    ABSTRACT: Titanium plate systems are used frequently for bone fractures and postosteotomy fixation in craniomaxillofacial surgery. However, sometimes the head of the screw for plate fixation is deformed or the screw breaks in the bone. Screw removal can be difficult in these cases. In this study, we examined the utility of the Screw Extraction Set (Synthes Inc) in facilitating the removal of screws broken in craniomaxillofacial bones. In the past, we often encountered screw head sockets that had become deformed. In the removal of such a screw, the extraction screw tip did not engage well with the deformed screw head socket because the extraction screw tip was angled obtusely. Thus, its removal was difficult, and this method was clearly problematic. Using the Screw Extraction Set, the removal method for a screw broken in the bone was relatively easy. In particular, it was very convenient in removing broken screws in the mandibular angle and ramus, where surgery is difficult under direct vision. This system was thought to be useful for craniofacial surgeons if proper patient selection is performed.

    ABSTRACT: Most reports regarding hardware removal involve the violation of the cortex to allow a specialized to tool to extract a retained fragment. This leaves large, unfilled screw holes that act as stress risers for months postoperatively. This article describes a novel technique to remove a retained intracortical screw fragment during total hip arthroplasty. Conversion of an intertrochanteric osteotomy to a total hip arthroplasty can be made more difficult by anatomical changes to the femur and retained hardware. Direct access to the intramedullary canal during total hip arthroplasty allowed for the safe removal of a retained intracortical screw using this technique.
