    Abstract:
    The success rate for leg replantation has improved with the development of shortening-lengthening protocols. We checked whether this success was maintained long term in five cases of emergency reimplantation. The significant initial shortening of 93 mm, on average, enabled direct internal osteosynthesis, secondary lengthening was initiated swiftly, in the proximal metaphyseal area, and average lengthening was 85 mm. Consolidation was achieved in all cases within normal time periods, with an average inequality in residual length of 8mm. The speed of nerve regeneration was on average 1.926 mm/day, twice faster than usual after simple nerve suturing. At average follow-up of more than 11 years, all patients were walking. We conclude that nerve lengthening stimulates nerve regeneration, and that the results of this protocol, involving extensive initial debridement compensated by secondary lengthening, have enabled the limitations on unilateral leg replantation to be reduced.
