BACKGROUND CONTEXT: The thoracic spine was previously known as a relatively stable region in human spine. Several studies reported motion of the thoracic spine and changes in the cross-sectional area of the spinal cord changed with positions in sagittal plane. The kinematic relationship between the thoracic disc and space available for cord with the positional change is still not well investigated. PURPOSE: To evaluate the kinematic change of the intervertebral disc and space available for the spinal cord of the thoracic spine using kMRI...

BACKGROUND: Cement augmentation techniques are standard treatments for osteoporotic vertebral fractures. Compared to vertebroplasty, kyphoplasty is associated with lower rates of cement leak and better deformity correction, however, posterior wall fractures are relative, but not absolute, contraindications for both techniques and hence treatment practices vary among spine centers. PURPOSE: The primary aim of this study was to assess our center's incidence of posterior cement leakage in osteoporotic vertebral fractures with posterior wall injury treated by balloon kyphoplasty...

Pelvic tilt is an essential parameter in spinal deformity surgery and in acetabular positioning for total hip arthroplasty. However, the measurement of tilt varies between the hip and spine literature. Hip surgeons measure the anterior pelvic plane tilt, whereas spine surgeons measure the spinopelvic tilt. This study uses stereoradiography (EOS imaging SA, Paris, France) to assess the relationship and the inter-observer and intra-observer reliability of measuring these two common references for pelvic tilt...

RATIONALE: Extremely sharp angular spinal deformity of healed tuberculosis can be corrected by vertebral column resection (VCR). However, the VCR techniques have many limitations including spinal column instability, greater blood loss, and greater risk of neurologic deficit. PATIENT CONCERNS: We described a new spinal osteotomy technique to collect sharp angular spinal deformity in Pott disease. A 52-year-old woman presented with back pain and gait imbalance. DIAGNOSIS: The kyphosis of healed tuberculosis was diagnosed based on history and imaging examinations...

BACKGROUND: Low bone mass in adolescent idiopathic scoliosis patients has been well reported. Poor bone quality was regarded as a new and unique prognostic factor in aggravating the curve progression. However, the potential biomechanical correlation between them remains unclear. METHODS: Three-dimensional finite element models of idiopathic scoliotic spine with different bone mineral status were created for axial loading simulation. Axial load of three different body weights were applied on different bone mineral mass models...

BACKGROUND: Nusinersen, the only treatment approved by the United States Food and Drug Administration for spinal muscular atrophy (SMA), is delivered intrathecally. Many children with SMA have extensive spinal instrumentation and deformities, often precluding the use of standard approaches for gaining intrathecal access. Furthermore the anatomical distortion that often occurs with rotoscoliosis can complicate the use of fluoroscopic guidance. Compared to fluoroscopy, CT affords superior guidance for complex needle placements...

STUDY DESIGN: Retrospective clinical study. OBJECTIVE: We aimed to introduce new parameters that can better describe the pelvic morphology and lumbosacral segmental deformity in children with high-grade spondylolisthesis of the L5 vertebra: modified pelvic incidence (mPI) and modified lumbosacral angle (mLSA). Also, we aimed to establish the mLSA as a convenient, reliable measurement method and criteria to evaluate the reduction of L5 vertebral slippage. SUMMARY OF BACKGROUND DATA: Numerous parameters and methods exist to evaluate segmental deformity and reduction of L5 vertebral slippage, but no definitive standard for accurately and conveniently describing lumbosacral kyphosis and degree of reduction exists...

Jae Yong Park, Chenyu Wang, Hee Dong Kim, Hyong Nyun Kim
BACKGROUND: Flexor hallucis longus (FHL) tendon rupture is a challenging injury to lead with clawing of the great toe when the FHL tendon is repaired too tight. When the diagnosis is delayed, the tendon ends may not be opposable because of contracture or poor tendon tissue. METHODS: A technique to reconstruct FHL tendon rupture without a free tendon graft is described. A split tendon lengthening is performed at the midfoot around the knot of Henry. Ankle block anesthesia is used to allow the patient's active movement of the interphalangeal (IP) joint to determine the appropriate length of the reconstructed tendon for maintaining balance and preventing the tendon from being too tight or too loose...

Dropped head syndrome (DHS) is a cervical kyphotic deformity caused by apparent weakness of the neck extensor muscles. We often encounter patients whose symptoms, including impaired forward vision and neck pain, deteriorate while walking. This is the first report of a case of dynamic spinal alignment change in a patient with DHS during walking using three-dimensional gait analysis. A 78-year-old Japanese woman complained of impaired forward vision and neck pain while walking. Her radiograph showed severe cervical kyphosis...

STUDY DESIGN: Grand Round case report. OBJECTIVE: We report a pancreatic fracture associated with Wirsung duct disruption, following a scoliosis surgery in a cerebral palsy adolescent. Spinal fusion surgery is the standard treatment for severe neuromuscular scoliosis. Many complications such as digestive ones account for its complexity. Postoperative acute pancreatitis is well described, although its pathophysiology remains unclear. To our knowledge, pancreatic fracture following scoliosis correction has never been described to date...

REVIEW
H Allouch, M Shousha, H Böhm
Ankylosing spondylitis is an inflammatory rheumatic disease that is often associated with back pain and restricted spinal movement. In the later stages of the disease, complete ossification of the entire spine and severe deformity can occur, often resulting in a marked reduction in quality of life and an increased risk of loss of independence due to diminished visual field. Patients with ankylosing spondylitis are at greater risk of spinal fractures. These are generally complex fractures associated with high morbidity and mortality; in addition, neurological deficits are not unusual...
