Major stump trauma following below-knee amputation. Outcome and recommendations for therapy.
Injury to the stump of a below-knee amputation (BKA) may require revision to a higher level of amputation. We undertook a retrospective review of BKAs performed during a 14-year period. Twenty-three patients suffered trauma to their stumps. Most (80%) trauma resulted from a fall. The severity of the trauma was graded on a three-part scale. Operative reclosure was attempted in 8 cases with 2 successes. Closure by secondary intent was successful in 7 of the 12 attempts. A total of 11 patients had revision to above-knee amputation (AKA) as the final outcome. The severity of trauma correlated inversely with the likelihood of eventual stump salvage. We conclude that primary reclosure or closure by secondary intent should be considered, since in 53% of attempts this results in knee preservation. Analysis of noninvasive vascular testing prior to the BKA was not helpful in predicting successful salvage of traumatized stumps.
