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

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 eas...

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...

Intertrochanteric osteotomy for avascular necrosis of the head of the femur. Survival probability of two different methods.

We have compared different types of intertrochanteric osteotomy for avascular necrosis of the hip and evaluated their performance in the light of improving outcome after total hip arthroplasty (THA). During a period of 14 years we performed 63 flexion osteotomies (partly combined with varus or valgus displacement), 29 rotational osteotomies, 13 varus osteotomies, eight medialising osteotomies a...

Rotational Acetabular Osteotomy

Hip dysplasia is the most common cause of secondary osteoarthritis (OA). To prevent the early onset of secondary OA, Nishio's transposition osteotomy, Steel's triple osteotomy, Eppright's dial osteotomy, Wagner's spherical acetabular osteotomy, Tagawa's rotational acetabular osteotomy (RAO), and Ganz' periacetabular osteotomy (PAO) have been proposed. PAO and RAO are now commonly used in surgic...
