Correction of combined angular and XXXX by the Ilizarov method.

@entity1 @entity281 @entity158 @entity717 @entity85
Deformities of the lower extremities are often a combination of angular and rotational components. The rotational component of @entity85 may be difficult to measure using plain radiography. Based on the current study, the computed tomography rotational malalignment test was developed. Evaluation of lower extremity alignment was done on 56 @entity1 . Rotational malalignment was diagnosed in 14 limbs of nine @entity1 . In all @entity1 , correction of angular and @entity717 was done simultaneously using an Ilizarov external fixator. The frame included a standard angular distraction system and a derotation block interconnected via an additional empty ring. In all cases, successful correction of angular and @entity717 was achieved. The @entity158 was eliminated in all seven @entity1 having preexisting chronic @entity158 . There were no cases of @entity281 or nonunion. This simple and reliable method allowed precise analysis of the deformity in the transverse plane. Preoperative frame construction incorporating the derotational module decreased the time of the operation and allowed one-stage correction of rotational and @entity85 without additional manipulations.
