Samples designated as high fracture risk (100% fracture risk in vertebral bodies able to sustain less than 1.6 MPa of stress) required a 20% fill to improve mechanical integrity to low fracture risk (able to endure stress over 2.7 MPa and 0% fracture risk).57 Although vertebral body
reinforcement prior to injury is an interesting concept, identifying which at-risk individuals will go on to suffer VCF and, thus, benefit from prophylactic intervention still remains a problem.
Any painful lesion involving the vertebral body
can benefit from vertebroplasty.
The FDA reviewed clinical data supporting the safety and probable benefit of The Tether - Vertebral Body
Tethering System from 57 patients who received the device.
Anteroposterior diameter of the vertebral body
C3 to C7.
(a) Left parasagittal CT showing an L2 fracture involving the vertebral body
and extending through the pedicle posteriorly.
In current study we used the bone graft which was taken from iliac crest for reconstruction which was fixed with Caspar plating after vertebral body
resection (figure 2).
The correlations among vertebral bone age and C3 and C4 vertebral body
heights were also found to be significant.
The needle is then advanced until it terminates near the center of the vertebral body
, no more than one half to two-thirds of the anterior-posterior (AP) dimension of the vertebral body
, taking care to avoid breaching the ventral vertebral body
cortex into the overlying anterior external venous plexus (Figure 7).
Superiorly, growth was extending horizontally from mid of upper border of vertebral body
to base of right transverse process of fourth lumbar vertebra.
Cobb angle and cord occupancy in the spinal canal of both groups significantly decreased (P less than 0.05) while height ratio of the injured vertebral body
significantly increased (P less than 0.05).
The Kiva implant is designed to provide structural support to the vertebral body
and a reservoir to direct and contain bone cement during vertebral augmentation.
A characteristic cervical vertebrae consists of vertebral body
, pedicle, lamina, transverse process, spinous process, and superior and inferior articular process (Drake et al., 2010).
