CT measurement of tibial torsion after internal fixation in patients suffering from unilateral tibial fracture

Objective: To study the CT technique for measurement of tibial torsion after internal fixation in patients suffering from unilateral tibial fracture. Methods: CT data of 27 patients suffering from unilateral tibial fracture and receiving internal fixation were analyzed retrospectively and compared with X-ray data. Results: Tibial torsions of 27 patients were successfully obtained with CT and they could not be accurately measured with X-ray. The tibial torsions in 26 patients showed no difference with those of the normal people, with 1 in 26 patients reaching 68°, indicating the presence of tibial torsional deformity. Conclusion: CT is convenient and precise in measuring the tibial torsion of patients suffering from unilateral tibial fracture and receiving internal fixation, and it is of great clinical significance.
