STUDY DESIGN Histologic changes in the spinal cord caused by progressive spinal kyphosis were assessed using a new animal model. OBJECTIVES To evaluate the effects of chronic compression associated with kyphotic deformity of the cervical spine on the spinal cord. SUMMARY OF BACKGROUND DATA The spinal cord has remarkable ability to resist chronic compression, however, delayed paralysis is so...

Osteoporotic vertebral fractures are well-known complications of rheumatoid arthritis. The management of multiple vertebral fractures with kyphotic deformity is controversial. We present a case of a patient with mutilating rheumatoid arthritis who had multiple vertebral fractures with kyphotic deformity after occipitothoracic fusion for rheumatoid cervical disorder. Occipitosacral fusion was ef...

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...

STUDY DESIGN In an in vivo sheep model, the effects of spinal fusion and kyphotic deformity on the neighboring motion segments were analyzed. OBJECTIVES To investigate the effects of spinal fusion and kyphotic deformity on the adjacent motion segment. SUMMARY OF BACKGROUND DATA The in vivo effects of kyphotic deformity on the neighboring motion segments have not been investigated in any stu...

There has been a large series in the literature reporting on results of osteotomy for the correction of kyphotic deformity secondary to post-traumatic thoracolumbar fracture. However, there are few reports on using intraoperative, full rotation, three dimensional image (O-arm)-based navigation, transpedicular wedge osteotomy for the correction of kyphotic deformity in old thoracolumbar fracture...

OBJECTIVE Observation of post treatment kyphotic angle in patient of cervical spine tuberculosis managed non operatively. BACKGROUND The incidence of tuberculosis of cervical spine is about 6-9%. The most dreaded complications of spinal tuberculosis are neural involvement and spinal deformity. Due to destruction of the vertebra tuberculosis of spine usually leads to variable amount of kyphoti...

Introduction Ankylosing spondylitis (AS), a chronic inflammatory arthritis, primarily involves the axial skeleton and results in severe thoracolumbar kyphotic deformity. Treating AS-related kyphotic deformity typically involves one or more posterior wedge osteotomies and manipulation of the position of the spine by forceful manual extension to close them. Several types of osteotomy are availabl...

 Abstract Background: Correction of severe kyphosis is a challenging operation in spinal surgery. A two stage operation has been commonly used: anterior release and decompression followed by posterior correction and fusion. We describe the posterior vertebral osteotomy technique for correction of severe and rigid kyphosis through posterior-only approach. Methods: Twelve patients (six male and s...

A 23-year-old male whose medical history included tuberculous spondylitis presented with a kyphotic deformity and incomplete paraplegia of twenty days duration. Preoperative radiographs demonstrated a T12-L4 kyphotic Cobb's angle of 100 degrees with a complete block showing on the lumbar myelogram at L4-5. The patient underwent anterior osteotomy and release. After the operation, a halo-pelvic ...
