A 16-year-old girl who had Morquio syndrome presented with severe bilateral hip pain and limited mobility because of bilateral hip osteoarthritis and fixed flexion deformities. She was wheelchair bound for the previous 6 months. Cervical spine flexion-extension views showed mild subluxation (<3 mm), and there was thoracolumbar spine kyphosis. Magnetic resonance imaging of the cervical and thora...

Complete thoracolumbar trauma evaluation incorporates radiographs, computed tomography, and magnetic resonance imaging. Primarily to localize the level of injury, diagnosis of thoracolumbar spine trauma begins with radiographs. Computed tomography with sagittal reformatted images is more sensitive for identifying the full extent of injury and the degree of involvement of the bony posterior elem...

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...

We report five children who presented at the mean age of 1.5 years (1.1 to 1.9) with a progressive thoracolumbar kyphosis associated with segmental instability and subluxation of the spine at the level above an anteriorly-wedged hypoplastic vertebra at L1 or L2. The spinal deformity appeared to be developmental and not congenital in origin. The anterior wedging of the vertebra may have been sec...

e advent of minimally invasive surgery has provided surgeons and patients the same good treatment alternatives. Within the �eld of spine surgery, techniques for lumbar interbody arthrodesis have shown enormous evolution. e retroperitoneal transpsoas lateral approach for the lumbar spine has revolutionized how interbody fusions can be performed more safely and with signi�cantly less morbidity....

BACKGROUND Traditional anterior and posterior approaches to the thoracolumbar spine are associated with significant morbidity. In an effort to eliminate these drawbacks, minimally invasive retropleural approaches have been developed. OBJECTIVE To demonstrate the feasibility and clinical experience of a minimally invasive lateral retropleural approach to the thoracolumbar spine. METHODS Seve...

OBJECTIVE To evaluate spine magnetic resonance imaging (MRI) inter-reader and intra-reader reliabilities using the thoracolumbar injury classification system and severity score (TLICS) and to analyze the effects of reader experience on reliability and the possible reasons for discordant interpretations. MATERIALS AND METHODS Six radiologists (two senior, two junior radiologists, and two resid...

Study Design Cohort study. Objective Expandable anterolateral plates facilitate the reduction of posttraumatic deformities of thoracolumbar spine injuries and are commonly used in cases of unstable injuries or compromised bone quality. In this in vitro study, the craniocaudal yield load of the osseous fixation of an anterior angular stable plate fixation system and the effect of polymethyl meth...
