Function and Upright Time Following Limb Salvage, Amputation, and Rotationplasty for Pediatric Sarcoma of Bone

Abstract

We wished to determine the relative physical and psychosocial merits of limb-sparing reconstruction, above-knee amputation, and rotationplasty in survivors of childhood and adolescent lower extremity bone sarcoma. In comparing minimum 5-year disease-free survivors, we found that outcome was somewhat dependent on the measuring tool administered. A superior score of statistical significance on the system of evaluation of the Musculoskeletal Tumour Society and a trend toward higher Toronto Extremity Salvage Scores were found among patients with a limb-sparing reconstruction compared with those with an above-knee amputation. Short-Form 36 results and the amount of time spent in the upright position (uptime), as assessed with a remote activity monitor, were similar between these groups. Uptime was highest in patients who had undergone rotationplasty, although statistical assessment of this group was not feasible. Psychosocial outcome was similar between all groups. This information may be useful in discussing reconstruction with patients and their families.
