There are two bones in the lower leg, below the knee. The larger of the two bones is the tibia. It is the shin bone and bears the majority of weight between the knee and the ankle. Lateral to (on the outer side of) the tibia is the fibula, a smaller long bone that provides stab...
The results of treatment of congenital pseudarthrosis of the tibia (CPT) are frequently unsatisfactory because of the need for multiple operations for recalcitrant nonunion, residual deformities, and limb-length discrepancies (LLD). Although the etiology of CPT is basically unknown, recent reports sugg...
A murine model of neurofibromatosis type 1 tibial pseudarthrosis featuring proliferative fibrous tissue and osteoclast-like cells In this study, we generated a novel fracture model to investigate the mechanism underlying congenital pseudarthrosis of the tibia (CPT) associated with NF1...

A bone graft which had the vascular pedicle from peroneal artery and vein was taken from the fibula in affected side. The graft was immobilized with two screws spanning a involved area, then the vascular pedicle of the graft and recipient vessels (A. and V. tibialis ant.) were anastomosed...
Evaluates the effect of fibular healing on deformity recurrence in CPT. Khan T, Joseph B. Controversies in the management of congenital pseudarthrosis of the tibia and fibula. Bone Joint J. 2013;95(8):1027–34. Article Google Scholar Dobbs MB, Rich MM, Gordon JE, Szymanski DA, Schoeneck...
Congenital pseudarthrosis of the tibia (CPT) is caused by an ill-defined, segmental disturbance of periosteal bone formation leading to spontaneous bowing, followed by fracture and subsequent pseudarthrosis in the first 2 years of life. The results of conventional treatment modalities (e.g., ...
The Paley cross-union protocol starts with preoperative zoledronic acid infusion to protect the tibia, fibula and autogenous bone graft from resorption by the hyperosteoclastic cells in CPT. This is combined by radical circumferential hamartoma resection from tibia and fibula. The bones are fixed ...
.ConclusionThe major risk factors for refracture after union of congenital tibia pseudarthrosis with the use of intramedullary nail combined Ilizarov external fixator are the smaller cross-sectional area of pseudarthrosis and with fibula pseudarthrosis.Key words:Pseudarthrosis;Tibia;Fracture fixation;Risk...
The problems include a recalcitrant pseudarthrosis of the tibia, deformity, limb length discrepancy, concomitant affected fibula in many cases, ankle valgus, and a notorious tendency for refracture after having healed. These problems are due to biological causes in the form of unhealthy avascular ...
A large variety of surgical procedures have been attempted for the treatment of fractured cases of CPT with an average rate of union without refracture of only 50%. Intentional cross-union between the tibia and fibula was proposed by both Choi and Paley and has been reported to improve the ...
