Information model for the evaluation of the efficiency of osteoplasty performing in case of amputations on below knee

Abstract

Based on the information model different variants of osteoplasty, taking into account the persistence, value of critical loading and flexibility of amputation stump below are substantiated. The studies of strength assessment and values of critical load on the stump below knee showed that osteoplastic amputations have obvious advantages as compared with myoplastic amputations. From the point of view of critical load rather long stumps are inferior to stumps in middle and upper thirds. The character of malleolus bones connection influences the conditions of stump functioning. The most rational are the connections conceptually similar with rigid bony bridge.
