Posterior Fixation Combined with Vertebroplasty or Vertebral Column Resection for the Treatment of Osteoporotic Vertebral Compression Fractures with Intravertebral Cleft Complicated by Neurological Deficits

Figure 1

The degree of local kyphotic angle (LKA) was measured from the upper endplate of the instrumented vertebra to the lower endplate of the instrumented vertebra below the fractured level. The anterior vertebral height (AVH) and posterior vertebral height (PVH) were measured as the distance between the upper and lower endplates at the anterior wall and posterior wall of the vertebral body, respectively.
