Assessment of tibial fracture union by 35-45 degrees internal oblique radiographs.

Thirty-five to 45 degrees internal oblique radiographs were used in the assessment of tibial fracture healing. This view is particularly helpful when routine radiographic examinations (anteroposterior and lateral) are nondiagnostic in assessing tibial fracture healing. The technique was helpful in the diagnosis of four occult nonunions as well as in showing the position of a bone graft when used. The authors recommend this view when a decision about tibial fracture healing cannot be made from routine radiographs. They recommend this view before resorting to tomograms of the tibia.
