Abstract:
OBJECTIVE:To explore the influencing factors of the residual back pain in patient with osteoporotic vertebral compression fractures(OVCFs) in the early and late stages after percutaneous vertebral augmentation(PVA), and analyze the correlation between these factors and the residual back pain after PVA.
METHODS:From March 2018 to December 2019, 312 patients with OVCFs who treated with PVA were collected. According to the inclusion and exclusion criteria, a total of 240 patients were included in this retrospective study. There were 59 males and 181 females, aged from 50 to 95 years old with an average of (76.11±10.72) years old, and 50 cases of fractures located in the thoracic region (T5-T10), 159 cases in the thoracolumbar region (T11-L2), and 31 cases in the lumbar region (L3 and below). The first day after PVA was regarded as the early postoperative period, and the seventh day was regarded as the late postoperative period. According to the visual analogue scale (VAS), the patients were divided into 4 groups:early postoperative pain relief group(group A, VAS≤4 scores), there were 121 patients, including 29 males and 92 females, aged from 50 to 90 years with an average of (75.71±11.00) years;early postoperative pain relief was not an obvious group (group B, VAS >4 scores), there were 119 patients, including 30 males and 89 females, aged from 53 to 95 years with an average of (76.51±10.46) years; late postoperative pain relief group (group C, VAS≤ 4 scores), there were 172 patients, including 42 males and 130 females, aged from 50 to 95 years with an average of (76.20±10.68) years; late postoperative pain relief was not obvious group (group D, VAS>4 scores), there were 68 patients, including 17 males and 51 females, aged from 53 to 94 years old with an average of (75.88±10.91) years old. The age, gender, bone mineral density(BMD), injured vertebral segment, preoperative thoracolumbar fascial condition, surgical methods, single or bilateral puncture, the amount of bone cement injection, anterior vertebral height recovery rate and central vertebral height recovery rate in the 4 groups were analyzed by univariate analysis. The statistically significant factors were put into a Logistic regression to analyze the correlation between these factors and residual back pain after PVA.
RESULTS:Univariate analysis showed that the residual back pain in the early stage after PVA was correlated with BMD, preoperative thoracolumbar fascial injury, single or bilateral puncture, the amount of bone cement injection, anterior vertebral height recovery rate and central vertebral height recovery rate(P<0.05). The residual back pain in the late postoperative period was related to BMD, injured vertebral segment, surgical methods, the amount of bone cement injection, anterior vertebral height recovery rate and central vertebral height recovery rate(P<0.05). Multivariate Logistic regression analysis showed that thoracolumbar fascial injury(OR=4.938, P=0.001), single or bilateral puncture(OR=5.073, P=0.002) were positively correlated with the residual back pain in the early stage after PVA(B>0), which were risk factors;the BMD (OR=0.211, P=0.000) and anterior vertebral height recovery rate (OR=0.866, P=0.001) were negatively correlated with the residual back pain in the early stage after PVA(B<0), which were protective factors. In the late stage after PVA, the BMD(OR=0.448, P=0.003), the amount of bone cement injection (OR=0.648, P=0.004) and anterior vertebral height recovery rate (OR=0.820, P=0.000) were negatively correlated with residual back pain(B<0), which were protective factors.
CONCLUSION:The decrease of BMD, injury of the thoracolumbar fascia, single or bilateral puncture, poor recovery of anterior vertebral height and insufficient injection of bone cement are closely related to the occurrence of residual back pain after PVA, which affect the relief of residual back pain in the early and late postoperative periods.
