An accurate method of determining a single-plane osteotomy to correct a combined rotational and angular deformity
نویسندگان
چکیده
Conventional osteotomy used for the correction of deformity is performed out of the plane of deformity creating a wedge either opening or closing when the deformity is corrected. Deformity that is a combination of rotation and angulation exists in a single plane that is oblique to the coronal, sagittal and axial planes depending on the magnitude of deformity measured in each plane. Accurate planning and a simple method of finding this oblique plane operatively is presented. This method starts by finding the bisector of angulation. This is marked by a wire that lies in the plane of angulation and along the bisector of angulation. The saw blade is rotated about this bisector axis according to the proportion of angulation and rotation. There is no second reorientation of the saw blade required making the final plane much easier to define. This single-plane oblique osteotomy allows accurate realignment of the limb.

A Simplified Way of Determining the Direction of a Single-cut Osteotomy to Correct Combined Rotational and Angular Deformities of Long Bones.
The direction of the obliquity of the cut for performing single-cut osteotomy to correct combined angular and rotational deformities is difficult to determine. The appropriate obliquity, i.e. whether clockwise or anticlockwise in relation to the perpendicular to the bone axis, is usually determined through trials using plastic bone models to imitate the deformity, or on bananas, on which differ...

متن کاملSingle Cut Distal Femoral Varus Osteotomy (SCFO): A Preliminary Study
Background: Genu valgum usually originates from a deformity of distal femur that is often corrected by distal femoralvarus osteotomy. The osteotomy includes both components of angulationcorrection and translation because the siteof osteotomy is not commonly at the apex of deformity. Improvement of patellar tracking not only depends on valguscorrection, but also it may be partially due to centra...

PURPOSE Past classification for the treatment of idiopathic genu vara depended simply on the measurement of distance between the knees, without attention to the rotational profile of the lower extremity. We retrospectively analyzed anatomical causes of idiopathic genu vara. PATIENTS AND METHODS Twenty eight patients with idiopathic genu vara were included in this study. All patients were surg...

BACKGROUND Codman's paradox reveals a misunderstanding of geometry in orthopedic practice. Physicians often encounter situations that cannot be understood intuitively during orthopedic interventions such as corrective osteotomy. Occasionally, unexpected angular or rotational deformity occurs during surgery.This study aimed to draw the attention of orthopedic surgeons toward the concepts of orie...
