Abstract
The essential problem in revision hip surgery is loosing of the implant in the bone, which causes various bone defects. According to a bad quality of the tissues the revision surgery is always difficult.
The use of the standard components is limited by a volume of remaining bone and by a possibility to fill in sufficiently bone defects created by a migration of a loosened endoprothesis. Most often in the final solution we are obliged to use a special oval socket corresponding to a defect by its shape and size.
In the case of a loosened femoral component we are forced to use a revision stem with a primary fixation in the healthy part of a femur diaphysis. One of the essential parts of the modern way of treatment is to promote the bone tissue remodeling and a new bone formation in the area of defects by using a various types of bone grafting to create more favorable conditions for revision surgery in the future.
The purpose of this article is to describe our view to diagnostics and to the treatment of aseptic loosening based on our five-year experience.
