Function of children with myelodysplasia and lower extremity amputations

This is a retrospective study of the functional status of children who underwent a lower extremity amputation for complications of myelodysplasia. With a computerized surgical database, 12 children with myelodysplasia who underwent an amputation at the Boyd level or above at a single children's referral hospital between 1983 and 2001 were identified. Four patients could not be contacted, but the remaining 8 patients were evaluated through chart review and interview to assess the impact of the amputation on their function. With a mean follow-up time of 9 years (range, 5-15 years), all 6 of the patients with a below-knee or Boyd amputation continued to ambulate using a prosthesis. Most patients occasionally reported having ulcers on their residual limb, but these cases were easily managed and did not result in amputation revisions. The only patient in this series with an above-knee amputation and the only patient with a knee disarticulation were exclusively wheelchair ambulators and no longer owned a prosthesis. This study supports the notion that children with myelodysplasia can have amputations and successfully wear a prosthesis to maintain their ambulation.
