AI Article Synopsis
- Achieving strong bone fixation in cases of megaprosthesis revision is challenging due to significant bone loss.
- A custom-made stem and cone were developed for a 36-year-old male with a failed distal femoral replacement after osteosarcoma treatment, preserving bone stock in the proximal femur.
- The patient regained normal function without assistive devices, and follow-up imaging confirmed stable implant fixation after one year, showcasing the effectiveness of the custom cone in avoiding a total femoral replacement.
Article Abstract
Achieving bone fixation during megaprosthesis revision presents a formidable challenge in view of the substantial bone loss. We report treatment of a failed revision distal femoral replacement in an active 36-year-old male mechanic remotely treated for osteosarcoma. A custom stem and cone were manufactured to augment fixation and preserve bone stock within a short segment of the remaining proximal femur. The patient returned to regular function without the need for assistive devices. Follow-up imaging demonstrated stable implant fixation at 1-year follow-up. While cones and sleeves have vastly improved fixation in revision knee arthroplasty, a custom-made cone for the proximal femur was used to augment fixation of a revision megaprosthesis and obviate the use of a total femoral replacement.
