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).
