Intraoperative rotational measuring device: a new device to achieve accuracy in corrective osteotomy of malrotated femur.
A new derotation device for corrective femoral osteotomy is reported. This device helps eliminate errors of undercorrection and overcorrection in derotational osteotomies of femurs with torsional deformities. A prototype of the intraoperative rotational measuring device was tested on 16 cadaver femurs. This experiment conclusively demonstrated that this simple device is easy to use and a mathematical precision (P < 0.05) is accomplished in rotational corrections by surgical means.
