BACKGROUND: Laminoplasty and laminectomy are two common surgical procedures utilized in approaching degenerative and neoplastic disease of the spinal canal. Routinely adopted instruments, such as Kerrison rongeur or high-speed drill (HSD), entail some potentially serious complications such as dura injuring and thermal and mechanical damage to neurovascular structures. We have adopted piezoelectric bone surgery, which permits a selective cut of mineralized tissues, to perform posterior procedures on the thoracic spine, where the relationship between bone and the spinal cord are critical...

BACKGROUND CONTEXT: Lumbar spinal stenosis is a common condition in the elderly for which costs vary substantially by region. Comparing differences between surgeons from a single institution, thereby omitting regional variation, could aid in identifying factors associated with higher costs and individual drivers of costs. The use of decision aids (DAs) has been suggested as one of the possible tools for diminishing costs and cost variation. PURPOSE: (1) To determine factors associated with higher costs for treatment of spinal stenosis in the first year after diagnosis in a single institution; (2) to find individual drivers of costs for providers with higher costs; (3) to determine if the use of DAs can decrease costs and cost variability...

In patients with pre-existent cervical spinal canal stenosis, minimal trauma, leading to neck hyperextension, can cause a significant increase of spinal cord compression. However, spinal cord injury is generally associated with major trauma and is usually not expected in patients with minor trauma. The resulting symptoms are diverse, making it even more difficult to diagnose. To illustrate the variety in symptoms at presentation, we describe two male patients aged 66 and 69. Rapid diagnosis is important as acute neurosurgical intervention may be indicated...

Osteoporotic patients can present with either single or multiple fractures secondary to repeated falls and progressive osteoporosis. Multiple fractures often lead to additional spinal deformity and are a sign of more severe osteoporosis. In the thoracic spine, multiple fractures are associated with the development of gradual thoracic kyphosis but neurologic deficits are uncommon. In the lumbar spine, patients with multiple lumbar fractures have more constant lumbar pain, may have symptoms related to concurrent lumbar stenosis or degenerative scoliosis, and may present with radiculopathy, especially with fractures at L4 and L5...

Pathogenesis-based diagnosis is a key step to prevent and control lumbar neural foraminal stenosis (LNFS). It conducts both early diagnosis and comprehensive assessment by drawing crucial pathological links between pathogenic factors and LNFS. Automated pathogenesis-based diagnosis would simultaneously localize and grade multiple spinal organs (neural foramina, vertebrae, intervertebral discs) to diagnose LNFS and discover pathogenic factors. The automated way facilitates planning optimal therapeutic schedules and relieving clinicians from laborious workloads...
