| 目的：探讨单一椎体骨质疏松性压缩性骨折行单侧PKP 术后对相邻上下椎体高度的影响。方法：62 例行T12 椎体骨质疏松
性压缩性骨折单侧PKP 术后的患者，测量术前，术后2 天、6 个月、1 年T11 椎体及L1 椎体前缘、中央及后缘高度，计算椎体压缩
率，比较两椎体各时相点椎体前缘、中央及后缘椎体压缩率的变化。结果：术后2 天L1 和T11 的椎体前缘、中央及后缘压缩率比
较差异无统计学意义(P 均>0.05)；术后6 个月、1 年后两椎体前缘、中央及后缘高度压缩率比较（P均<0.05）差异有统计学意义。
L1 和T11 术后2 天、6 个月、12 个月不同时相，三点压缩率越来越大，差异有统计学意义(P均<0.05)。结论：单侧PKP术后椎体相
应负荷的改变，对下位邻近椎体较上位椎体高度影响较大，可能与相邻下位椎体承受的重力高于上位相邻椎体有关。 |

| Objective:To investigate the influence of the unilateral PKP on the adjacent vertebral height of patients with single
vertebral osteoporotic compression fractures.Methods:From2007 to 2010, 62 patients with T12 vertebral osteoporotic compression fractures
were included in this research and received PKP surgery, including 18 males and 44 females. The age was from65 to 82. The anterior
edge, the central and posterior height, vertebral compression ratio of the T11 and L1 were calculated at 2 days, 6 months and 1 year
after the surgery through imaging technology.Results:The difference of the anterior edge, the central and posterior height compression
ratio of T11 and L1 did not have statistical significance at 2 d after surgery (P>0.05). But these indexes had statistical difference at 6
months and 1 year after surgery (P<0.05). The anterior edge, the central and posterior height compression ratio of L1 and T11 was different
at postoperative 2 days, 6 months and 12 months, and the compression ratio was increasing slowly along with the time (P<0.05).Conclusion:The PKP surgery changed the line of unilateral vertebral body and increased the local stress of adjacent vertebral bodies. It had
greater influence on the lower adjacent vertebrae than the upper one, and this may be related to that lower adjacent vertebral bodies take
greater gravity than the upper adjacent vertebral bodies. |
