Periprosthetic hip infection treated with two-stage stage-one Select Spacer- complication rate and restoration of anatomy.

Two-stage revision with 'StageOne™ Select Hip Cement Spacer' is used as treatment of periprosthetic hip joint infection. The aim is to evaluate complications and restoration the joint with the StageOne Select Spacer. From 2013 to 2018 twenty-nine StageOne Select Spacers was inserted. Data was obtained through medical records and radiographs. 3.5% dislocated the spacer, 6.9% sustained a femoral fracture, 6.9% got reinfected and 6.9% failed to control the infection. Leg length discrepancy was 1.5 mm (-4,25-5.25) and offset discrepancy was 4 mm (-0.5-9). The spacer shows promising results with a low reinfection and dislocation rate and allowance of restoration of the joint.
