Background

This study aims to investigate the utility of the Doppler effect on ultrasonography for the diagnosis of very early- and early-stage lumbar spondylolysis in adolescent patients.

Methods

In total, 76 adolescent patients with acute and subacute low back pain were prospectively enrolled, with 46 having lumbar spondylolysis and the remaining 30 having low back pain without spondylolysis. MRI and/or computed tomograms scans revealed very early- and early-stage lumbar spondylolysis. Furthermore, positive Doppler findings in ultrasonography around the area from the facet joint to the laminae were investigated.

Results

There were no significant differences in age (p > 0.99) and body mass index (p = 0.11) between cases with and without spondylolysis. Very early- and early-stage spondylolysis were observed in 27.6% and 72.4% of patients, respectively. Positive power Doppler was 91.3% and 33.3% in cases with and without spondylolysis, respectively, which was significantly higher in spondylolysis (p < 0.001). The sensitivity and specificity of this positive power Doppler were 91.4% and 66.7%, respectively. Furthermore, the rate of positive power Doppler was significantly higher in early-stage spondylolysis (p = 0.02), with 75.0% and 97.6% sensitivity in very early- and early-stage spondylolysis, respectively.

Conclusions

A positive Doppler effect on ultrasonography is effective for screening very early- and early-stage spondylolysis in adolescent patients in an outpatient clinic.

超声检查在青少年腰椎峡部裂诊断中的应用

背景

本研究旨在探讨超声多普勒效应在青少年患者极早期和早期腰椎峡部裂诊断中的实用性。

方法

总共有 76 名患有急性和亚急性腰痛的青少年患者被纳入前瞻性研究，其中 46 名患者患有腰椎峡部裂，其余 30 名腰痛患者不伴有椎弓峡部裂。MRI 和/或计算机断层扫描显示极早期和早期腰椎峡部裂。此外，还研究了从小关节到椎板周围区域超声检查的阳性多普勒结果。

结果

患有 和不患有椎弓峡部裂的病例之间的年龄（ p  >0.99）和体重指数（p =0.11）没有显着差异。极早期和早期椎弓峡部裂的发生率分别为 27.6% 和 72.4%。有和没有椎弓峡部裂的病例中，功率多普勒阳性率分别为 91.3% 和 33.3%，其中椎弓峡部裂的患者明显更高 ( p  < 0.001)。该正能量多普勒的敏感性和特异性分别为 91.4% 和 66.7%。此外，早期椎弓峡部裂的阳性功率多普勒率显着较高（p  = 0.02），极早期和早期椎弓峡部裂的敏感性分别为 75.0% 和 97.6%。

结论

超声检查的正多普勒效应可有效筛查门诊青少年患者的极早期和早期椎弓峡部裂。
