External fixation device with changeable angle for trochanteric fractures

摘要

The external fixation device is used in surgical orthopaedics and traumatology for stabilization (osteosynthesis) of fractures, osteotomies, arthrodesis e.t.c.;Specially, in trochanteric fractures, until now, there is not described any special external nail which can permit compression or sliding at the area of the trochanteric fracture to increase stabilization and consolidation.;In internal osteosynthesis, nails or plates are placed internally with serious hemorrhagic open intervention without the nail or the plate being left outside of the skin.;The disclosure gives the possibility, without serious hemorrhagic open intervention, to place a special nail which is left outside the skin to be connected with an external fixation device in such a way as to cause compression or sliding on the trochanteric fracture in a direction parallel with the nail, and also it is possible to correct, if it is needed post-operatively, varus or valgus deformity.;It is also possible easily post-operatively to insert or extract the nail as it has a screwed end for the stabilization of the head and the neck of the femoral bone and this is impossible with internal nails without open hemorrhagic intervention.;The external fixation device with changeable angle for trochanteric fractures, as disclosed, is characterized mainly by that it includes a long external nail threaded at one end which can cause compression or sliding on a trochanteric fracture .
