In the article “Total hip replacement after femoral neck fractures in elderly patients: Results of 8,577 fractures reported to the Norwegian Arthroplasty Register” published in Acta Orthopaedica 2007; 78 (4): 491–497 by Gjertsen J-E et al. errors have occurred in the article text and in the headings and text to .
Correct article text
In Results, page 494, first paragraph, the last sentence should be changed to:
For the sequelae patients, the relative risk of revision was increased due to infection during the first 2 weeks, and due to dislocations during the first year postoperatively, as compared to OA patients.
In Discussion, page 494, first paragraph, sentence 3 should be changed to:
The outcomes were, however, inferior to those in the OA patients-mainly due to more infections in the first two weeks and more dislocations in the first year after surgery, and due to more peripros-thetic fractures.
In Discussion, page 495, third paragraph, the first sentence should be changed to:
In the time-dependence study, we found a statistically increased risk of revision due to infection during the first 2 weeks in the sequelae group relative to OA patients.
Correct :
Figure 2. Time dependent relative risks (RRs) of revision, with 95% confidence intervals, for prostheses in patients with sequelae after femoral neck fractures compared to prostheses in OA patients. The horizontal red dotted line indicates overall RR. The horizontal black line represents the risk of revision in OA patients. The x-axis is logarithmic. The curves show an increased overall RR of revison due to any cause during the first year (A), an increased RR for revision due to infection during the first 2 weeks (B), and an increased RR for revision due to dislocation during the first year (C).
