A new method of achieving accuracy in osteotomy of any long bone

The use of basic trigonometrical principles enables the translation of theoretical pre-operative estimations for the correction of bony deformities in long bones into accurate wedge resections at surgery without the need for templates or the use of goniometer in a restricted operative field. The method described has been shown both to be accurate and simple, obviating the need for extra instrumentation and undue manipulation during surgery.
