Limb salvage in bone sarcomas in patients younger than age 10: a 20-year experience.

The authors present their experience over the last 20 years in limb salvage procedures of a consecutive series of 40 children under 10 years of age (range 2-10 years) with bone sarcomas. Nineteen were osteogenic sarcomas and 21 were Ewing sarcomas. Only one case, located in the distal phalanx of the toe, was treated by straightforward amputation. Intercalary allografts and Canadell's technique were used to preserve joints whenever possible, and prosthesis or osteoarticular allografts were used when the joint surface was involved. Survival rate in this series was 75%. There were four local recurrences. At the last follow-up (mean 11.2 years, range 5-19 years postop), 90% of the patients preserved their limbs. Eighty percent of the authors' results were excellent or good according to the Musculoskeletal Tumor Society Scale. Limb salvage is a real possibility even in young children with bone sarcomas. The age of the patient itself is not a contraindication for limb salvage.
