目的
2
探究血清半胱氨酸蛋白酶抑制剂C(CysC)与骨小梁评分(TBS)对老年骨质疏松性椎体骨折术后骨折再发的预测价值。
方法
2
选择2022年6月—2023年6月100例于重庆大学附属涪陵医院就诊并进行手术治疗的老年骨质疏松性椎体骨折患者,随访2年,根据术后骨折再发情况分为不良组(31例)与良好组(69例)。Pearson分析血清CysC与TBS相关性,Cox分析老年骨质疏松性椎体骨折术后骨折再发的影响因素,ROC分析血清CysC及TBS对患者术后骨折再发的预测价值。
结果
2
不良组骨水泥渗透比例、血清CysC显著高于良好组(
χ
2
=4.977,
P
=0.026;
t
=4.749,
P
=0.000),术后抗骨质疏松治疗比例、骨密度T值、TBS显著低于良好组(
χ
2
=4.229,
P
=0.040;
t
=2.065,
P
=0.042;
t
=5.163,
P
=0.000)。血清CysC与TBS呈负相关(
r
=-0.318、
P
=0.001)。血清CysC升高是老年骨质疏松性椎体骨折术后骨折再发的危险因素(
P
<0.05),TBS升高是老年骨质疏松性椎体骨折术后骨折再发的保护因素(
P
<0.05)。血清CysC预测患者术后骨折再发的AUC为0.786(95%CI=0.679-0.894)、灵敏度为77.42%、特异度为71.01%,TBS预测患者术后骨折再发的AUC为0.795(95%CI=0.698-0.892)、灵敏度为74.19%、特异度为79.71%,两者联合预测患者术后骨折再发的AUC为0.858(95%CI=0.773-0.943)、灵敏度为74.19%、特异度为82.61%,两者联合对患者术后再发骨折的预测价值更高。
结论
2
老年骨质疏松性椎体骨折术后骨折再发的患者血清CysC升高、TBS降低,血清CysC与TBS两者联合对老年骨质疏松性椎体骨折术后骨折再发有一定预测价值。
Objective
2
To explore the predictive value of serum cystatin C (CysC) and trabecular bone score (TBS) for postoperative fracture recurrence in elderly patients with osteoporotic vertebral fractures.
Methods
2
A total of 100 elderly patients with osteoporotic vertebral fractures who were treated surgically at Fuling Hospital Affiliated to Chongqing University from June 2022 to June 2023 were followed up for 2 years. They were divided into the poor group (31 cases) and the good group (69 cases) based on the postoperative fracture recurrence. Pearson analysis was used to analyze the correlation between serum CysC and TBS, Cox analysis was used to analyze the influencing factors of postoperative fracture recurrence in elderly patients with osteoporotic vertebral fractures, and ROC analysis was used to analyze the predictive value of serum CysC and TBS for postoperative fracture recurrence in patients.
Results
2
The proportion of bone cement penetration and serum CysC in the poor group were significantly higher than those in the good group (
χ
2
= 4.977,
P
= 0.026;
t
= 4.749,
P
= 0.000), while the proportion of postoperative anti-osteoporosis treatment, bone mineral density T value, and TBS were significantly lower than those in the good group (
χ
2
= 4.229,
P
= 0.040;
t
= 2.065,
P
= 0.042;
t
= 5.163,
P
= 0.000). Serum CysC was negatively correlated with TBS (
r
= -0.318,
P
= 0.001). Elevated serum CysC was a risk factor for postoperative fracture recurrence in elderly patients with osteoporotic vertebral fractures (
P
<
0.05), while elevated TBS was a protective factor (
P
<
0.05). The AUC of serum CysC for predicting postoperative fracture recurrence in patients was 0.78
6 (95%CI = 0.679-0.894), with a sensitivity of 77.42% and a specificity of 71.01%. The AUC of TBS for predicting postoperative fracture recurrence in patients was 0.795 (95%CI = 0.698-0.892), with a sensitivity of 74.19% and a specificity of 79.71%. The AUC of the combination of serum CysC and TBS for predicting postoperative fracture recurrence in patients was 0.858 (95%CI = 0.773-0.943), with a sensitivity of 74.19% and a specificity of 82.61%. The combination of the two had a higher predictive value for postoperative fracture recurrence in patients.
Conclusions
2
Elderly patients with osteoporotic vertebral fractures who experience postoperative fracture recurrence have elevated serum CysC and decreased TBS. The combination of serum CysC and TBS has a certain predictive value for postoperative fracture recurrence in elderly patients with osteoporotic vertebral fractures.
