- Abstract:
- Objective To explore the initial efficacy of a new telescopic rod in the treatment of congenital pseudarthrosis of tibia in children.Methods A new type of telescopic rod for children was designed and its clinical results were evaluated.There were 9 cases of congenital pseudarthrosis of tibia on the right and 6 cases on the left;There were 6 females and 9 males.The average operative age was 35.5(19-72) months.There were 12 cases with neurofibromatosis type 1 and 4 cases with proximal tibial dysplasia.Initial healing of tibial pseudarthrosis,proximal tibial valgus deformity,tibial length,ankle valgus,ankle function and intramedullary rod displacement were evaluated during follow-ups.Results During a follow-up period of 13.2(10-20) months,14 cases achieved initial healing (14/15),with an average healing time of 4.3(3.5-5.5) months.Ten cases had unequal length of tibia,with an average of 0.9(0.4-2.0) cm.Proximal tibial valgus occurred in 7 cases and ankle valgus (17 °) occurred in 1 child.The average range of motion of ankle joint was 23°(20°-30°) and the average plantar flexion 42°(40°-50°).The average extension of new telescopic rod was 1.6(0.4-3.4) cm.The displacement of telescopic rod occurred in 7 cases,there was no epiphyseal plate tethering and re-fracture.Conclusion New children’s telescopic rod has reasonable design and can extend with the growth of tibia.There are no complications of epiphyseal plate tethering and re-fracture.The operation is simple.It provides a new choice of intramedullary fixation for the treatment of congenital pseudarthrosis of tibia
