Complex Radiological Findings in Congenital Pseudarthrosis of the Tibia

Objective: To study changes of bone and soft tissues in patients with congenital pseudoarthrosis by MSCT and MRI. Methods: We studied condition of bone and soft tissues at the site of congenital pseudoarthrosis of the tibia before commencing treatment, using radiographic methods- multi slice computed tomography (MSCT), magnetic resonance imaging (MRI) in order to make prognosis of treatment outcome and recurrence of the disease. Results: 25 patients with congenital pseudoarthrosis of the tibia (CPT) in the age group 8 to 40 years were examined by above mentioned radiographic methods, multi slice computed tomography (MSCT), magnetic resonance imaging (MRI) before treatment and after recurrence. The peculiarities and changes in structure of tibial and fibular cortex, periosteum and muscles at the site of pseudoarthrosis. We derived at complex findings and changes that cause recurrence, of pseudarthrosis after deformity correction, or treatment. We developed criteria for evaluation of bone quality in patients with CPT. Conclusion: Structural changes in the soft tissue and the bone at the site of CPT, detected by MRI and MSCT, allow for rather precise interpretation of condition of bone, periosteum, muscles during various stages of treatment and this information can be used to choose appropriate technique and methods of treatment. Keywords: Pseudarthrosis; Tibia; Multi Slice Computed Tomography (MSCT); Magnetic Resonance Imaging (MRI) Key Points • Use of MSCT and MRI for study of pseudoarthrosis made it possible to determine complex changes of bone and soft tissues. • Changes of the tibia in patients with CPT were described as “Complex changes of CPT”. • Criteria for evaluation of bone quality in patients with CPT were introduced
