Stay Short or Go Long? Can a Standard Cemented Femoral Prosthesis Be Used at Second-Stage Total Hip Arthroplasty Revision for Infection Following an Extended Trochanteric Osteotomy?

Petrie, Michael J. et al.


The aim of this study was to review the results of the use of a cemented, standard length, taper-slip femoral component at second stage following an extended trochanteric osteotomy (ETO).


We reviewed prospectively collected data from the hospital arthroplasty database, identifying and reviewing all patients who had undergone an ETO at first-stage revision for infection, who had subsequently undergone second-stage reimplantation.


Over 17 years, 99 patients underwent 102 2-stage procedures with ETO at first stage, with a mean follow-up of 5.5 years; 70 of 102 patients received a standard prosthesis following ETO union and 32 of 102 patients received a long-stem prosthesis at second stage because of deficiencies in proximal femoral bone stock. There was a significant difference in the Paprosky classification between the 2 groups (P < .0001); 77% of the standard group and 52% of the long-stem group had no complications. A significant complication (infection, fracture, or dislocation) was observed in 12% patients in the standard group and 16% patients in the long-stem group. A number of radiographs were independently reviewed to assess for ETO union and complications and an intraclass correlation of 0.84 (P < .0001) was observed.


A standard femoral prosthesis can be implanted at second stage following ETO union for Paprosky type I and some type II femora. There is no greater risk of complications, and distal bone stock is preserved for potential revision surgery in the future.
