OBJECTIVE Posterior vertebral translation as a type of spondylolisthesis, retrolisthesis is observed commonly in patients with degenerative spinal problems. Nevertheless, there is insufficient literature on retrolisthesis compared to anterolisthesis. The purpose of this study is to clarify the clinical features of retrolisthesis, and its developmental mechanism associated with a compensatory ro...

BACKGROUND Treatment of unstable upper and middle thoracic spine fractures remains controversial. There is no consensus regarding optimal treatment. OBJECTIVES In this study, we evaluated the efficacy of pedicular screw in the management of middle thoracic spine fractures to correct kyphosis and anterolisthesis and improve neurologic condition of patients. PATIENTS AND METHODS Twenty-five p...

OBJECTIVE To measure the orientation of the facet joints of cervical spine (C-spine) segments in the sagittal plane, known as the pedicle-facet (P-F) angle, and to use these measurements to evaluate the relationship between the P-F angle and the amount of vertebral anterolisthesis in patients with degenerative cervical spondylolisthesis (DCS). METHODS A retrospective case-control study was pe...

BACKGROUND AND PURPOSE The association between L5 hypoplasia and bilateral spondylolysis was described earlier on conventional radiographs of the lumbar spine. The purpose of this study was to describe the findings on MR imaging in patients with hypoplasia of L5 and to correlate these findings with the presence of bilateral spondylolysis of L5. MATERIAL AND METHODS We studied the MR images of...

STUDY DESIGN A retrospective cohort study. OBJECTIVE To clarify the influence of cervical spondylolisthesis on neurological outcomes in cervical spondylotic myelopathy (CSM) patients after cervical laminoplasty. SUMMARY OF BACKGROUND DATA Studies focusing on the surgical outcomes in CSM patients with cervical spondylolisthesis are limited. METHODS We retrospectively reviewed 125 CSM patie...

conclusions application of pedicular screw in unstable upper and middle thoracic spine fractures is an effective method that can correct kyphotic deformity and anterolisthesis and improve neurologic deficit. background treatment of unstable upper and middle thoracic spine fractures remains controversial. there is no consensus regarding optimal treatment. objectives in this study, we evaluated t...

PURPOSE Over 170 years ago, traumatic spondylolisthesis of the axis or hangman's fracture was described. Most descriptions of this entity have focused on adult presentations. METHODS We review the literature on pediatric cases of hangman's fracture emphasizing the embryological as well as presentation aspects. RESULTS The majority of cervical spine fractures in children occur at C1 and C2 v...

Osteoradionecrosis, a rare complication of radiation therapy, is a slow progression disease which affects the surrounding structures of spinal components. It essentially weakens the soft tissue and bony configuration and can cause nerve impingement or cord compression. We describe a patient who underwent radiotherapy for thyroid cancer and presented with cervical kyphosis with anterolisthesis o...
