Background: The purpose of this study was to determine the incidence of surgery for odontoid fractures and to study surgical mortality, surgical morbidity and long-term outcome in a large, contemporary, consecutive, single institution, surgical series of odontoid fractures. Methods: This is a retrospective study of all odontoid fractures treated by open surgery at our hospital during 2002–2009....

OBJECTIVES This study aims to retrospectively review the short-term surgical outcome of wrist fusion using wrist fusion rod (WFR). PATIENTS AND METHODS Six wrists of four female patients (mean age 56 years; range 51 to 62 years) with advanced stage rheumatoid arthritis of Larsen IV or V were performed total wrist fusion using WFR. Clinical outcome was assessed using a numeric rating scale of ...

In this issue, we explore the role of biologics in spinal fusion. The treatment disorders has been revolutionized over last 25 years with introduction to enhance bone density preparation for surgery and promote bony arthrodesis fusion surgery. use these products become even more important era minimally invasive surgery, where graft surface area is at a premium.Use osteobiologics known migration...

Revision surgery for os odontoideum with irreducible atlantoaxial dislocation with a transoral approach is not commonly seen. Typically, management of this type of atlantoaxial dislocation is through posterior fixation and fusion or transoral decompression and posterior fusion. This report describes revision surgery in a patient with os odontoideum who was treated with a transoral approach. A 5...

We report 2 cases of transforaminal lumbar interbody fusion for failed Graf ligamentoplasty. Both patients had residual or recurrent low back pain and leg pain after Graf ligamentoplasty, caused by lumbar segmental instability or narrowing of their intervertebral foramens. The pain improved markedly after the revision surgery. We recommend transforaminal lumbar interbody fusion for failed Graf ...

Atlantooccipital fusion is complete or partial congenital fusion of the atlas to the base of occiput. Basilar impression may complicate the clinical picture with the reduction of the vertical height of atlas causing odontoid or other bony structures project into foramen magnum and medulla oblongata. This results in narrowing of the foramen magnum and leads to neural compression. Authors present...
