title: [Medial dislocation of hip screw following internal fixation of a pertrochateric metastasis in the femur with gamma nails].
abstract: If the standard technical guidelines are ignored so that the antirotation screw is not correctly placed during gamma nail osteosynthesis, dislocation of the hip screw is possible. In the rare cases of migration into the pelvis, the consequences may be lethal.
