BACKGROUND: Osteoporotic vertebral compression fracture, all the time accompanied with ache and top lack of vertebral physique, has a major detrimental impression on life high quality of sufferers. Vertebroplasty or kyphoplasty is minimal invasive methods to reconstruct the vertebral top and forestall additional collapse of the fractured vertebrae by injecting polymethylmethacrylate into vertebral physique. Nonetheless, recompression of polymethylmethacrylate augmented vertebrae with important vertebral top loss and aggressive native kyphotic was noticed incessantly after VP or KP. The aim of this research was to research the impact of polymethylmethacrylate distribution on recompression of the vertebral physique after vertebroplasty or kyphoplasty surgical procedure for osteoporotic vertebral compression fracture.
METHODS: A complete of 281 sufferers who have been identified with vertebral compression fracture (T5-L5) from June 2014 to June 2016 and underwent vertebroplasty or kyphoplasty by polymethylmethacrylate have been retrospectively analyzed. The X-ray movies at 1 day and 12 months after surgical procedure have been in comparison with consider the recompression of operated vertebral physique. Sufferers have been divided into these with out recompression (non-recompression group) and people with recompression (recompression group). Polymethylmethacrylate distribution sample, together with location and relationship to endplates, was in contrast between the 2 teams by lateral X-ray movie. Multivariate logistic regression evaluation was carried out to evaluate the potential threat components related to polymethylmethacrylate distribution for recompression.
RESULTS: 100 and 6 (37.7%) sufferers skilled recompression after surgical procedure in the course of the follow-up interval. The polymethylmethacrylate distributed in the course of vertebral physique confirmed important variations between two teams. In non-recompression group, the polymethylmethacrylate within the center portion of vertebral physique have been nearer to endplates than that within the recompression group (higher: t = 31.41, p<zero.001; decrease: t = 12.19, p<zero.001). The upper share of the peak of polymethylmethacrylate within the center portion of vertebral physique signifies the decrease threat of recompression (odds ratio [OR]<zero.01, p<zero.001). The recompression group and non-recompression group confirmed important distinction in “contacted” polymethylmethacrylate distribution sample (polymethylmethacrylate contacted to the each higher/decrease endplates) (?2 = 66.23, p<zero.001). The vertebra with a “contacted” polymethylmethacrylate distribution sample has decrease threat of recompression (OR = zero.09, p<zero.001).
CONCLUSIONS: Both extra polymethylmethacrylate within the center portion of vertebral physique or “contacted” polymethylmethacrylate distribution sample had a considerably much less incidence of recompression. The findings indicated that the management of polymethylmethacrylate distribution throughout surgical procedure could scale back the dangers of recompression after vertebroplasty or kyphoplasty.
