Spondylolysis is the term used for a defect in the pars interarticularis of the vertebra. The term is from the Greek roots spondylos, meaning vertebra, and lysis, meaning break or defect. Spondylolisthesis is from spondylos and listhesis, meaning movement or slipping, and refers to the slipping forward of one vertebra on the next caudal vertebra. Spondylolisthesis was first described in 1782 by...

Injuries of the vertebral artery are rare and are usually seen after penetrating or blunt cervical trauma. Vertebral artery injuries (VAI) have been reported in 0.5% of blunt trauma cases. These injuries can lead to hemorrhage, thrombosis, arteriovenous fistula or traumatic pseudoaneurysm in the early or late period. They must be treated carefully due to their increased risk of morbidity and mo...

Man has a swollen head and a shrunken, atavistic tail. Yet, in Nature’s eye the two are on par. It is fascinating to realize that the well-recognized lumbosacrolisthesis has a cranial counterpart in transatlantic Odonto-Occipital Listhesis or TOOL in short. Nature’s penchant for embryologically treating the hind-area (proctodeum) on par with the mind-area (stomodeum) gets reflected even in the ...

A 43-year-old drug addicted female was referred for a L5-S1 posterolateral in situ fixation with autologous graft because of an L5/S1 severe discopathy with listhesis. After six months, low back pain recurred. A Tc-99m HDP SPECT-CT diagnosed a pseudarthrosis with intense uptake of the L5-S1 endplates and a fracture of the right S1 screw just outside the metal-bone interface without any uptake o...

ABSTRACT Objective: evaluate the correlation between main sacropelvic alignment measurements and pelvic retroversion reduction assessing Lamartina Square effectiveness in choosing proximal instrumentation level. Methods: sample comprising 21 patients with high-grade L5 -S1 spondylolisthesis subjected to arthrodesis from January 2004 December 2016. Patients’ demographic data, surgery type, compl...

BACKGROUND The vacuum phenomenon within the intervertebral disc usually represents disc degeneration. There are no reports in the English literature that focus on the effect of an anterior vacuum disc on surgical outcome of same-segment spondylolisthesis. METHODS Patients with degenerative spondylolisthesis (DS) or isthmic spondylolisthesis (IS) who underwent a spinal surgery between January ...

BACKGROUND Although a substantial percentage of patients with rheumatoid arthritis (RA) experience low back pain, the characteristics of lumbar spine pathology in RA patients has been poorly investigated. In our institutions, lumbar spine radiographs indicated scoliosis in 26 patients. The present study aimed to clarify the characteristics of lumbar scoliosis in RA patients. METHODS This is a...
