Telescopic rod in a combined surgical technique for the trea
A Study was conducted to investigate the initial effect of the “telescopic rod” in a combined surgical technique for the treatment of congenital pseudarthrosis of the tibia in children.

Study included 15 patients with Crawford type IV CPT who were treated using a combined surgical technique and the telescopic rod. The average age at the time of surgery was 43.3 months. Of the 15 patients, 7 had proximal tibia dysplasia and 12 exhibited neurofibromatosis type 1.

The combined surgical technique using the telescopic rod included the excision of pseudarthrosis, intramedullary rod insertion, installation of Ilizarov’s fixator, tibia-fibular cross union, and wrapping autogenic iliac bone graft. The incidence of refracture, ankle valgus, tibial valgus, and limb length discrepancy (LLD) in patients were investigated.

--All patients achieved primary union with an average follow-up time of 37.3 months.

--The mean primary union time was 4.5 months (4.0–5.6 months).

--9 cases showed LLD, with an average limb length of 1.1 cm. Ankle valgus, proximal tibial valgus, telescopic rod displacement, and epiphyseal plate tethering occurred in 1 case (18°), 3 cases(10°, 5°, and 6°, respectively), 6 cases, and 2 cases, respectively.

--There were no refractures during the follow-up periods.

Conclusively, Although there are complications such as intramedullary rod displacement while using the telescopic rod in a combined surgery, the primary healing rate of congenital pseudarthrosis of the tibia in children is high.
