CORR Insights^®: How Often Does Spindle Failure Occur in Compressive Osseointegration Endoprostheses for Oncologic Reconstruction?

Excerpt

For patients with a primary bone tumor of the lower extremity, limb-salvage surgery is the preferred approach when it is feasible to perform [4]. For patients undergoing distal-femur resections, endoprosthetic reconstructions allow immediate partial weight bearing and generally restore an acceptable level of limb function [9]. Traditional fixation approaches, including cement or press-fit intramedullary stems, depend in large measure on the amount of remaining bone into which the surgeon can anchor the device; the longer-term survivorship of these implants becomes critically dependent upon that sometimes-scarce resource. Among patients who survive for longer periods of time, aseptic loosening can result in additional disability and major surgery [6, 10]. …
