Femoral Revision Using the Wagner SL Revision Stem: A Single-Surgeon Experience Featuring 11-19 Years of Follow-Up.

Seventy-four revisions of the femoral component featuring placement of a Wagner stem in 74 patients operated upon between 1995 and 2003 were reviewed. Clinical evaluation, radiological assessment, and survival analysis of revision stems were conducted. The mean follow-up duration was 14.4 years (range, 11 to 19 years). When failure was defined as stem removal for any reason, 4 of 64 stems had to be further revised during the follow-up period, yielding a cumulative stem survival rate of 93.8% (95% CI: 87.7% to 98.2%) at 18 years. The Wagner revision stem is an effective implant for revision hip surgery when bone stock is lacking. Use of the stem affords mechanical stability even when bone loss is massive.
