Use of a locking compression plate in the management of congenital pseudarthrosis of the tibia

Congenital pseudarthrosis of tibia is a rare condition and it is highly associated with neurofibromatosis. The goals of surgery are to restore the tibial alignment, achieve bone union and re-establish the length of the tibia. The treatment includes resection of the pseudarthrosis followed by fixation with external fixation devices to perform callus distraction, intramedullary nail or open reduction and plate fixation in combination with bone graft. We present a case of a 16-year-old male with underlying neurofibromatosis and congenital pseudarthrosis of right distal third of tibia. Patient was treated with excision of the pseudarthrosis followed by reduction and fixation using locking compression plate and bone graft. Radiograph showed union of the tibia at eight months postoperation. Patient had limb length discrepancy of 10 cm and was ambulating with a shoe raised. At two years follow-up, there was no refracture of the tibia. The patient was satisfied with his current functional status and had adapted well. Due to his good functional outcome, he declined to undergo limb lengthening surgery. We thereby concluded that locking compression plate may be considered as a suitable option for the treatment of congenital pseudarthrosis of tibia.
