The aim of this study was to identify the prevalence of proximal junctional kyphosis (PJK) in degenerative lumbar scoliosis (DLS) following long instrumented posterior spinal fusion, and to search for predictable risk factors for the progression of junctional kyphosis.In total 98 DLS patients with a minimum 2-year follow-up were reviewed prospectively. According to the occurrence of PJK at the ...

REASONS FOR PERFORMING STUDY Thermographic imaging is an increasingly used diagnostic tool. When performing thermography, guidelines suggest that horses should be left for 10-20 mins to 'acclimatise' to the thermographic imaging environment, with no experimental data to substantiate this recommendation. In addition, little objective work has been published on the repeatability and reliability o...

OBJECTIVE The optimal treatment of "unstable" thoracolumbar injuries remains controversial. Studies have shown the advantages of direct anterior decompression of thoracolumbar injuries along with supplemental posterior instrumentation as a combined or staged procedure. Others have also shown success in decompression as a single-stage anterior procedure, largely limited to two-column (anterior a...

background: the accuracy of pedicle screw placement is essential for lumbar and thoracolumbar spine fracture fixation. purpose: the aim of the present study was to assess the accuracy of the pedicle screw placement with conventional c-arm fuoroscopy-guided in these patients. methods: a retrospective review identified patients who underwent operative management with thoracolumbar instruments at ...

BACKGROUND CONTEXT Both bone graft and metallic implants have been used in combination with the necessary anterior rod or plate instrumentation to fill the voids left by vertebral body removal, with the ultimate goal of restoring stability. One type of device that has recently been introduced is an expandable titanium telescoping cage that is designed to be used as a strut implant to fill corpe...

BACKGROUND We have occasionally observed clinically noticeable postoperative transverse plane pelvic rotation increase (TPPRI) in the direction of direct thoracolumbar/lumbar rotational corrective load applied during posterior instrumentation and arthrodesis for double (Lenke 3 and 6) adolescent idiopathic scoliosis (AIS) curves. Our purposes were to document this occurrence; identify its frequ...

There are various methods for measuring kyphosis after thoracolumbar burst fracture. The reliability and reproducibility of these methods are not well defined. In the study reported here, we examined 4 commonly used measurement methods in order to determine intraobserver variability, interobserver variability, and variability between measurement methods. All 4 methods were found to be accurate ...

Thoracolumbar fractures occur from any and all forms of trauma. Twenty percent of them may be associated with neurological deficits. In high energy trauma, up to 5% of patients will have non-contiguous fractures (i.e. segmental fractures.) Sixty percent of patients with spinal cord injuries will have associated non-spinal injuries. The management of thoracolumbar fractures continues to evolve. ...

The authors present the advantages and disadvantages of the Denis and AO classifications based on a review of classical and recent literature concerning the evolution of classification of thoracolumbar spine conditions. The newest classification of fractures proposed by Vaccaro (TLICS - Thoracolumbar Injury Classification Severity Score) is discussed in detail. Special attention is given to ins...
