[Methods of Measuring Limb Malrotation Following Femoral Osteosynthesis].

Significant malrotation of the femur after osteosynthesis is a serious complication of treatment and has a number of consequences for the patients and causes deterioration of their quality of life. Therefore, it is necessary to be familiar with intraoperative techniques to control the correct rotation, mostly clinical and radiological, which give us the possibility to minimize rotational errors. In the postoperative period, with even a slight suspicion of malrotation, it is necessary to proceed to its exact verification and, in indicated cases, to perform necessary correction. We recommend one of the CT techniques as a very reliable method, however in younger patients we prefer to use MRI. Early diagnosis of the rotational error and especially its size is essential from the point of view of potential reconstructive surgery, which is then chosen also with regard to the location of the original lesion. Key words: femoral osteosynthesis, limb malrotation, methods of measuring.
