Osteotomies are performed on almost every bone and are commonly performed to correct congenital, degenerative, and traumatic osseous deformities and to improve function and cosmesis. It is vital for radiologists to have an understanding of the wide range of surgical osteotomies and to be familiar with reporting clinically relevant findings during surgical planning and follow up. In this exhibit we discuss the indications, techniques, post-operative imaging appearance, and key reporting elements of some of the more commonly performed osteotomies and provide a rich set of accompanying cases. There is currently no comprehensive review of osteotomies published in the radiology literature. This exhibit will address this by providing a comprehensive review of osteotomies that are likely to be encountered in clinical practice.

Educational Goals / Teaching Points
Discuss the indications for the most commonly encountered surgical osteotomies, from head to foot. Discuss the techniques for the above-mentioned osteotomies to the extent that they are relevant to clinical radiology. Provide readers with a general framework that can be used in evaluating pre and post-osteotomy images. Discuss common postoperative complications and expected postoperative apperance of the above osteotomies, including clinical relevant items to report on. Provide a high quality set of representative diagrams and images to familiarize readers with the appearance of osteotomies.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Cover the educational objectives above as they apply to the following types of osteotomies, including craniotomy, lateral nasal osteotomy, bilateral sagittal split osteotomy, reduction malarplasty, thoracolumbar vertebral osteotomy, rib osteotomy, external rotation humeral osteotomy, ulnar shortening osteotomy, distal radius corrective osteotomy, scaphoid corrective osteotomy, peri-acetabular osteotomy, high tibial osteotomy, talar neck osteotomy, calcaneal osteotomy, and hallux valgus osteotomy.

For just about every bone in the body, there is a surgical osteotomy that can be done to help with function, alignment, or cosmetics. Though it is impossible to learn about every osteotomy, it is important to be aware of common osteotomies seen in clinical practice. This exhibit provides the imaging appearance and clinical implications of common osteotomies to help trainees identify the procedure performed, use appropriate terminology to describe the procedure, and recognize the clinical implications on follow up imaging.
