Abstract [en]

Background: We present the first medium- to long-term follow-up of revision total hip arthroplasty using impaction bone grafting (IBG) combined with the matte and collared Lubinus SP II stem for cases of severe osteolysis and stem loosening.

Methods: Sixty-nine femoral revisions were identified for 67 patients consecutively operated with revision femoral arthroplasty using IBG and a cemented Lubinus SP II stem. The mean age was 69 years (standard deviation, 9.9). We retrospectively analyzed 68 cases (1 was lost to follow-up). At the time of the revision surgery, all had substantial femoral bone loss. Fifteen of the revisions were performed due to deep infection. The patients were analyzed by clinical score and radiography.

Results: At follow-up, 4 femoral components (6%) had been rerevised or assessed as failure. Of these 4, 3 were assessed as mechanical failure, and 1 for dislocation; none was for infection. Three cups (4%) had been revised for dislocation; 1 of these also had a stem exchange. Three cases (4%) had been reoperated for a periprosthetic fracture in distal femur without stem exchange. Radiologic results were excellent and the clinical Merle d'Aubigne-Postel score had improved from a mean of 12.2 preoperatively to 17.5 at follow-up.

Conclusion: IBG combined with the Lubinus SP II stem is safe and results in a low rate of periprosthetic fractures and dislocations. The medium-to long-term clinical result was excellent, with regeneration of living bone in the femur.
