Spine fractures in patients with ankylosing spondylitis frequently extend to all 3 columns, which can lead to displacement and deformity with severe instability. Cervical spine fractures occasionally cause severe kyphotic deformities, such as chin-on-chest deformities. In such cases, the patients typically exhibit a chronic progression of hyperkyphosis after the traumatic event. This article de...

The mechanisms for developing long-lasting neck pain after whiplash injuries are still largely unrevealed. In the present study it was investigated whether a kyphotic deformity of the cervical spine, as opposed to a straight or a lordotic spine, was associated with the symptoms at baseline, and with the prognosis one year following a whiplash injury. MRI was performed in 171 subjects about 10 d...

Purpose: Complications from RA can involve the thoracolumbar spine and cause severe spine instability and sagittal deformity. We present a surgical strategy to restore sagittal balance in a patient with chronic rheumatoid arthritis. Methods: A retrospective chart review was performed. Results: We report the case of a 53-year-old woman with RA and severe back pain. She had dynamic instability of...

BACKGROUND Cobb measurement of standing radiographs is the standard for clinical assessment of coronal spinal deformity. Angle of trunk inclination (ATI) is an accepted clinical measurement of trunk asymmetry, and has variable reported correlations with Cobb angles. Transverse plane spine deformity is most accurately measured using axial computed tomography. Aaro and Dahlbourn's technique for q...

Study Design Retrospective cross-sectional study. Clinical Question What is the prevalence of cervical spondylosis (CS) and thoracolumbar (TL) spinal deformity in an administrative database during a 4-year study period? Is the prevalence of CS or TL deformity higher in patients who have the other spine diagnosis compared with the overall study population? Are patients with both diagnoses more l...

Can J Surg, Vol. 45, No. 3, June 2002 219 A idiopathic scoliosis (AIS) involves a deformity of the spine that is commonly assessed by physicians. The external trunk deformity is also recognized as a major concern in AIS, especially for the patient. Therefore, many authors advocate that that consideration be given to simultaneous surgical correction of spinal and trunk deformities. During poster...

There can be many different reasons for lumbar spine instability to occur. Nevertheless, the most common reason is the natural degeneration of the spine. Instability of the vertebral column means that within the corresponding movement segment there might possibly be abnormal mobility. Long-term, the compensatory mechanisms of the spine cannot counteract this abnormal mobility. Over time, a defo...

Ankylosing spondylitis is a chronic illness affecting the spine/pelvic limb joints and sacroiliac, resulting in ankylosis deformity of spine. Hip can be affected on both sides, making them more susceptible prone to significant injury than other joints. Even though novel biological therapies have drastically altered management this illness, surgical intervention still necessary some cases. To ev...

Introduction Pseudotail is uncommon congenital malformation of the spine, it contains bone, cartilage, notochord and elements of spinal cord. Usually presented as protrusion of the coccygeal vertebra. It may come as solo deformity or in association of tethered cord, myelomeningoceol and other spine deformity, can be part of syndrome, never been reported. It’s different from true tail, which usu...

Multiple techniques exist for the fixation of C2, including axial pedicle screws and bilateral translaminar screws. We describe a novel method of incorporating both the translaminar and pedicle screws within C2 to improve fixation to the subaxial spine in patients requiring posterior cervical instrumentation for deformity correction or instability. We report three cases of patients with cervica...
