Twenty-year review of tibial lengthening for poliomyelitis

Twenty-four patients treated for tibial shortening secondary to poliomyelitis were reviewed at least 20 years after operation. All subjects were active and only one expressed doubt about the value of tibial lengthening, considering the period of hospitalisation to have been a significant drawback. Approximately five centimetres were added to the length of the treated tibiae. Only one of the nine patients with lengthening of over five centimetres was able to walk at a rate of more than five kilometres per hour, compared with seven of the remaining 15 whose tibiae had been lengthened five centimetres or less.
