Background: The objective of this study was to examine the degree of osteointegration into a hydroxyapatite-coated collar and relate this finding to aseptic loosening in patients with a distal femoral replacement used to treat primary bone cancer. Our hypothesis was that the implant collar would increase osteointegration and reduce the rate of aseptic implant loosening.
Methods: Sixty-one patients treated with a primary cemented distal femoral prosthesis between 1992 and 2001 were included in this study.
Article Synopsis
- Eight patients received custom-endoprosthetic elbow reconstructions between 1989 and 2006 due to complications from total elbow replacements or fractures.
- A functional assessment showed that seven patients showed positive outcomes after an average follow-up of 46.1 months, with a mean Toronto Extremity Salvage (TES) score of 67.3.
- The average elbow flexion deformity was 15 degrees with an average flexion arc of 85 degrees, indicating generally satisfactory functional results for this type of reconstruction.
Computer aided musculoskeletal tumor surgery is a novel concept. Ideally, computer navigation enables the integration of preoperative information concerning tumor extent and regional anatomy to facilitate execution of a surgical resection. Accurate resection helps oncological clearance and facilitates precise fitting of a custom prosthesis.
