A simplified guide ruler from numeric table method in doing rotational osteotomy

چکیده
BACKGROUND Cobeljić et al. recently reported a numeric table method to provide precise rotational osteotomy which is a well established orthopaedic procedure. The numeric table requires four pages in length that is rather inconvenient during performing an osteotomy operation. METHODS We thus develop our own method by summarizing the data of the four-page table into a small ruler, which is easy to carry and use in operation room. An electrical version of this ruler is also available. We also build a computer model to verify Cobeljić et al. method. RESULTS The error of Cobeljić et al. is between -37% to 16% (mean +/- SD = -6% +/- 9%). We verify our ruler by calculating the absolute difference between our method and that of Cobeljić et al. The difference is less than 0.1 mm. CONCLUSION Our ruler is convenient for practical use for the rotational osteotomy procedure with equal precision. Further clinical verification is needed to justify its real significance.

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...

Background & Objectives: The lateral nasal osteotomy is an integral part of cosmetic surgery (rhinoplasty). A reproducible and predictable technique with the least complication is a significant contributor to operation success. Regarding the different techniques and instrumentation for osteotomy, this study was carried out with the aim of comparison of ecchymosis severity due to lateral osteoto...
متن کاملEstablishing a Customized Guide Plate for Osteotomy in Total Knee Arthroplasty Using Lower-extremity X-ray and Knee Computed Tomography Images.
BACKGROUND The conventional method cannot guarantee the precise osteotomies required for a perfect realignment and a better prognosis after total knee arthroplasty (TKA). This study investigated a customized guide plate for osteotomy placement in TKAs with the aid of the statistical shape model technique using weight-bearing lower-extremity X-rays and computed tomography (CT) images of the knee...
