Summary

Cortical fenestration is an effective bone-preserving technique for extracting failed megaprostheses, especially fractured or cemented stems. This method reduces revision rates for loosening and avoids new periprosthetic fractures.

Area of Science:

Orthopedic surgery
Biomedical engineering
Reconstructive surgery

Background:

Common megaprosthesis failures include aseptic loosening, infection, and stem fracture.
Surgical techniques for implant exposure during revision can impact outcomes and re-revision rates.
Evaluating novel extraction methods is crucial for improving revision arthroplasty success.

Purpose of the Study:

To assess the efficacy of cortical fenestration in megaprosthesis revision surgery.
To specifically evaluate its effectiveness in cases of stem fracture.
To compare outcomes based on implant fixation type (cemented vs. press-fit).

Main Methods:

Retrospective review of 196 limb salvage cases (distal femoral/proximal tibial megaprostheses) from 1985-2014.

Keywords:

Analysis of revision rates for cemented (109) and press-fit (87) implants.

Assessment of cortical window use for stem extraction, particularly in stem fracture cases.

Main Results:

Revision for stem failure occurred in 27% of cemented and 18% of press-fit implants.
Stem fracture was a reason for revision in 13% of cemented and 6% of press-fit cases.
Cortical windows were used in 10 initial revisions (7 cemented, 3 press-fit), including all stem fractures.

Conclusions:

Cortical fenestration is a bone-preserving technique for implant extraction.
It is particularly effective for removing cemented or fractured stems.
This method is associated with low rates of re-loosening and no increased periprosthetic fractures.
