[Long-term results of revisional hip alloplasty using the X-change technique]

In this paper the authors evaluate the long-term results of revisional hip alloplasty using the X-change technique with an Exeter endoprosthesis. This evaluation is performed using clinical material consisting of 52 operated patients, namely 41 female patients (78.8%) and 11 male patients (21.2%). In order to evaluate achieved results the authors propose such time criteria that performed remodelling of implanted bone grafts allows for full weight-bearing on the operated limb. They emphasize the importance of well-performed operation according to the rules of X-change technique, the way of implanting homogenous frozen bone and the way of cementing the implant, which all are indispensable to the success of the operation. Following those steps, the authors have achieved full remodelling of bone grafts between 12 and 16 month since the day of the operation.
