Purpose


Recent studies suggest endplate fracture incurred during vertebral compression fracture (VCF) alters intervertebral disc mechanics at the adjacent levels [1], buy generic Sleep Aid. Where can i find Sleep Aid online, The deformity created by the endplate fracture leads to increased nucleus volume, which does not allow the nucleus to pressurize, Sleep Aid over the counter, Canada, mexico, india, and thus alters disc behavior. This altered disc behavior has recently been theorized to increase fracture risk adjacent to an endplate deformity, buy Sleep Aid from mexico. This study tested the hypothesis that reduction of endplate deformity after both endplate fracture and subsequent vertebral compression fracture will restore disc mechanics.



Methods & Materials


Six thoraco-lumbar spine segments (T10-L2, T12-L4, or L1-L5 age:72.2±6.4yrs) were tested, buy Sleep Aid without prescription. Buy generic Sleep Aid, A void was created under the upper endplate of the middle vertebra. The specimen was compressed via follower load until the weakened endplate fractured and a notable endplate deformity was observed on digital fluoroscopy, order Sleep Aid from mexican pharmacy. Online buy Sleep Aid without a prescription, The specimen was then compressed further to create a vertebral compression fracture. The compression fracture was corrected, buy Sleep Aid without prescription, Purchase Sleep Aid online, as observed radiographically, taking special care to correct the endplate deformity as much as possible using the StaXx® FX Structural Kyphoplasty device (Spine Wave, Sleep Aid coupon, Buy cheap Sleep Aid, Inc., Shelton, Sleep Aid over the counter, Buy Sleep Aid no prescription, CT). Buy Sleep Aid without prescription, Specimens were tested in flexion-extension (±6Nm) under 400N preload before and after endplate and vertebral fractures and after endplate deformity reduction. Lateral radiographs were taken in neutral posture under 400N preload to measure maximum endplate deformity, where can i find Sleep Aid online. Buy cheap Sleep Aid no rx, Intradiscal-pressure (IDP) in flexion-extension was recorded in the discs above and below the fractured body and normalized so pressure in neutral position was taken to zero.



Results


Vertebral height after endplate and vertebral fracture was significantly less than intact (73.3±9.1% and 67.7±6.0% of intact respectively, p<0.001) (Figure 1A-B), Sleep Aid price. Buy Sleep Aid from mexico, Vertebral height was significantly increased after endplate fracture reduction (p<0.001), but remained significantly less than intact (89.0±9.3% of intact, Sleep Aid samples, Order Sleep Aid no prescription, p=0.014) (Figure 1C).

Intact IDP increased 0.12±0.13MPa during flexion under 400N preload. After endplate and vertebral fractures the disc with endplate fracture developed significantly less IDP at maximum flexion in the disc with endplate fracture than intact (32±19% and 34±7.8% of intact respectively, Sleep Aid trusted pharmacy, Buy Sleep Aid without a prescription, p<0.004). After endplate fracture reduction IDP during flexion was restored to 73±47% of intact (p=0.162), and was significantly improved compared to after endplate and vertebral fractures (p<0.03) (Figure 2A), buy Sleep Aid without prescription. The IDP during flexion was not significantly affected in the disc below the fractured vertebra, buy Sleep Aid online cod, Buy Sleep Aid online no prescription, where the endplates remained intact throughout testing (Figure 2B).



Conclusion


The inability of the disc with a damaged endplate to develop normal intradiscal pressure during flexion was previously shown to increase loading of the anterior cortex of the adjacent vertebra and may increase the risk of subsequent fracture. Although reduction of the endplate fracture with StaXx FX did not fully restore the endplate to its intact condition, where can i buy Sleep Aid online, Rx free Sleep Aid, enough correction of the endplate deformity was achieved to improve the disc’s load sharing ability. Further studies are needed to investigate whether the reduction of endplate fracture will alleviate the risk of adjacent fractures.
