Comparison of screw malposition and vertebral artery injury of C2 pedicle and transarticular screws: meta-analysis and review of the literat...
Our review identified a higher risk of VAI, neurological injury, and clinically significant malpositions with TAS compared with C2PS. These data provide preliminary support for the supposition that C2PS have a lower risk of morbidity....
Result of posterior instrumentation without fusion in the management of thoracolumbar and lumbar unstable burst fracture.
We enrolled 60 patients who received only posterior instrumentation without fusion for thoracolumbar and lumbar unstable burst fracture between September 1, 2003 and December 31, 2009 at our hospital and who were available for longer than 12-month follow-up observation after the implant removal. For...
Clinical and computed tomographic evaluation of safety and efficacy of facet screw fixation in the subaxial cervical spine.
We modified the trajectory to direct the screws laterally from the sagittal plane to place the root at less risk and improve fixation by increasing the excursion of the screws into bone. No clinical reports exist describing the quadricortical facet screw placed in a lateral direction. A total of 95...
Assessment of presurgical psychological screening in patients undergoing spine surgery: use and clinical impact.
We analyzed the 110 (32%) responses with a χ(2) test (significance, P<0.05). PPS was used by 37% (41) to screen for depression (100%) or anxiety (85%). PPS use was highest among surgeons with more experience, higher annual volume, and no university affiliation. Among those screening for fear avoidan...
The retrospective analysis of the effect of balloon kyphoplasty to the adjacent-segment fracture in 171 patients.
We performed a retrospective analysis of 171 patients treated with percutaneous kyphoplasty. The follow-up period was 41.04±21.78 months. The occurrence of new symptomatic VCF was recorded after the procedure. We evaluated the variables of patient age and sex, the amount of injected cement, the init...
Radiation exposure for fluoroscopy-guided lumbosacral epidural steroid injections: comparison of the transforaminal and caudal approaches.
We evaluated and compared the radiation exposure caused by using the fluoroscopy-guided transforaminal and caudal approaches of lumbosacral epidural steroid injection (ESI). Only a few studies focused on the radiation exposure to patients who underwent lumbosacral ESI for pain management. A total of...
Perioperative variations of the intracompartmental pressures of the paraspinal muscles.
Study of the influence of thoracolumbar spinal surgery through a posterior approach to the intercompartmental pressure of the paraspinal muscles. To create waveforms according to the pressure variations up to 24 hours postoperatively and relate these measurements to independent parameters. The exist...
Pulsed Electromagnetic Field (PEMF) plus BMP-2 upregulates intervertebral disc-cell matrix synthesis more than either BMP-2 alone or PEMF al...
We decided to carry out an experiment whereby we combined PEMF with BMP-2. Our thoughts were that BMP-2 plus PEMF could be better than either alone. The PEMF signal used was similar to that used in the clinical treatment of fracture nonunions or delayed fracture healing. Human disc cells were treate...
Prospective Evaluation of Quality of Life in Adolescent Idiopathic Scoliosis before and after Surgery.
: Surgical treatment of AIS improved patient quality of life, as shown by significant improvement on all SRS-30 and SF-36 domains. Questionnaire scores did not correlate with Cobb angle, curve correction, or type of instrumentation....
Cervical endplate and facet arthrosis: an anatomic study of cadaveric specimens.
An anatomic, epidemiologic study of cervical endplate and facet arthrosis in cadaveric spines. To determine the prevalence of cervical endplate and facet arthrosis and the relationship between these 2 entities in a large population sample. Cervical endplate and facet arthrosis are common radiographi...
