Abstract

Lower extremity intercalary allograft reconstruction has traditionally been used to facilitate limb salvage. Combining the allograft with a free vascularized fibula graft has been described; however, there is a paucity of data comparing the outcome of these reconstructions. Twenty-nine pediatric patients (15 boys and 14 girls) underwent lower extremity limb salvage with the use of intercalary cadaveric allograft at a mean age of 12 years. The most common diagnosis was osteosarcoma (n = 18). Patients underwent reconstruction with an allograft alone (n = 11) or supplemented with a free vascularized fibula graft (n = 18). The mean time to union of the allograft was 11 months, with 10 patients requiring additional bone grafting. There was no difference in the need for an additional bone graft (OR, 0.87; p = 1.0) between patients with a free vascularized fibula graft and those without. The allograft was revised in three patients because of fracture (n = 2) and fracture and infection (n = 1). In all of these patients, the allograft was not supplemented with a free vascularized fibula graft (p < 0.001). Five patients underwent an amputation, most commonly for disease recurrence. At last follow-up, the mean Mankin and Musculoskeletal T...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
