Failure of the femoral component after a primary or revision THA is commonly associated with some degree of femoral bone loss. Depending on the quantity and quality of the remaining host bone, femoral stem revision can be challenging.

Twenty patients with severe proximal femoral bone loss due to prosthetic loosening were treated by Wagner cementless self-locking revision stems with a mean follow up of 24 months (range 18–36 months). The indication of revision surgery was aseptic loosening in 16 patients and septic loosening in 4 cases.

At the end of the follow up the mean Harris hip score increased from 35 to 86 points. Definite radiographic evidence of bone regeneration in the bony defects was achieved within 3 months in all patients.

Implantation of a Wagner cementless selflocking revision stem provided satisfactory results. The Wagner SL Revision prosthesis, firmly and rotationally stable fixed in the medullary cavity of the healthy bone distal from the original prosthetic bed, with its conical longitudinal ribs and cementless anchorage, bridges the defective prosthetic bed and hereby leads to a condition of relative mechanical stability. With time, there is active ossification in the old prosthetic bed, replacing lost bone.

Background

In young patients with femoral neck non-union it is desirable to preserve the femoral head. The objective of this study was to assess the outcome results of revision internal fixation and nonvascular fibular bone grafting

Background

Revision THA presents significant challenges for the surgeon when the proximal femur is deficient or mechanically unreliable. The aim of this study is to assess the clinical and functional results of the use of tumor enndoprosthesis to reconstruct the proximal femur when there is massive bone loss.
