Background and purpose: Bone fusion is a dynamic process and availability of calcium and balance of vitamin D can be effective in post spinal cord fusion. There are contradictory results on this issue, so, we decided to compare the effect of administration of vitamin D and alendronate on lumbosacral vertebral fusion in patients undergoing posterior spinal fusion surgery. Materials and methods:...
OBJECTIVES To identify the negative effect on treatment results of reserving damaged intervertebral discs when treating type B and type C spinal fracture-dislocations through a one-stage posterior approach. METHODS This is a retrospective review of 53 consecutive patients who were treated in our spine surgery center from January 2005 to May 2012 due to severe thoracolumbar spinal fracture-dis...
STUDY DESIGN Technical report on cadavers. OBJECTIVE To evaluate preliminary feasibility and safety of lumbar sagittal alignment correction with anterior hyperlordotic cages used to overpower previous posterior spinal instrumentation. METHODS Hyperlordotic 30° anterior lumbar interbody fusion (ALIF) cages were inserted in collapsed L5-S1 disc space of 2 cadavers to overpower prior posterior...
Background: Lumbar degenerative spondylolisthesis (LDS) is a degenerative slippage of the lumbar vertebrae. We aimed to evaluate the surgical outcome of degenerative spondylolisthesis with neural decompression, pedicular screw fixation, reduction, and posterolateral fusion.Methods: This before-after study was carried out on 45 patients (37 female and 8 male) with LDS operated from August 2008 t...
Introduction: Cranial traction leading to 6th nerve palsy is the main cause of developing diplopia following spinal surgery. Very few cases of abducens nerve palsy as a complication of surgery without cranial traction have been described. We review a series of four patients who developed diplopia following spinal surgery only one of which had cranial pins or apparent traction on the abducens ne...
Distal junctional kyphosis (DJK) is a radiographic finding in patients that undergo spinal instrumentation and fusion, since there is an abrupt transition between fixed and mobile spinal segments.The true incidence of DJK is variable in literature and seems that has a multifactorial etiology. A consecutive series of 130 patients (mean age 15.6 years) with adolescent idiopathic scoliosis who und...
