The revision of failed total hip artrhroplasty (THA) is a difficult challenge in
reconstructive hip surgery due to severe femoral bone loss. Our Study describes 138
hips that underwent to cementless femoral revision arthroplasty between 2004 and
2009 with a proximal porous coated, modular titanium alloy stem (S-
ROMJohnson&Johnson). According to Paprosky’s femoral defect classification, the
patients were classified in: type I (17 %) type II (39%) type III (33%) and type IV
(11%). All patients patients were present for the final follow-upevaluation and were
evaluated clinically (HHS, WOMAC, SF-12 and Satisfaction Test), comparing prewith
postoperative results. Radiographic analysis was performed based onthe Engh's
criteria. HHS improved from 32.8 to 76.2. 132 stems presented stable bony ingrowth,
6 was stabilized by fibrous tissue. Mechanical failure rate and re-revision rate were
zero. Eight years survival rate was 100%, with re-revision as endpoint. Evaluation of
bone loss and residual bone stock before surgery are indicative to determine the best
surgical choice. No complications were imputable to the S-ROM implant that
demonstrates to be an effective implant to reduce pain and restore hip function in
revision hip arthroplasty surgery.
