hi welcome, Often, poliomyelitis is unilateral, causing limb-length inequality, which occasionally requires limb lengthening. In leg lengthening for patients with poliomyelitis, callus maturation is slow and patients tend to develop contractures despite physiotherapy, bracing, or joint fixation. Concomitant and secondary surgery are frequently required to treat associated problems or residual deformities. Lengthening along an intramedullary locked nail can significantly shorten the treatment time with relatively few complications thanking you christyjoseph1@gmail.com
