PURPOSE
To assess the use of preoperative, dynamic ultrasound to predict ulnar nerve instability following in situ decompression for cubital tunnel syndrome.
METHODS
Prior to undergoing in situ decompression, 43 consecutive patients underwent dynamic ultrasound to assess the stability of the ulnar nerve during elbow flexion. The dynamic ultrasound findings were compared with the intraoperative assessment of nerve stability following in situ decompression.
RESULTS
The preoperative dynamic ultrasound agreed with intraoperative findings in 38 of 43 patients (88%). Physical examination of ulnar nerve stability agreed with the intraoperative findings in 5 of 43 patients (12%). For the 5 of 43 cases in which the dynamic ultrasound did not correlate with the degree of ulnar nerve stability after in situ decompression, dynamic ultrasound overestimated the degree of ulnar nerve stability in 4 cases.
CONCLUSIONS
Preoperative dynamic ultrasound can be used to accurately predict the degree of ulnar nerve instability following in situ decompression.
TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic II.
目的
评估术前动态超声在预测原位减压治疗肘管综合征后尺神经不稳定方面的应用。
方法
在接受原位减压之前，43例连续患者接受动态超声检查，以评估肘关节屈曲时尺神经的稳定性。将动态超声检查结果与原位减压后神经稳定性的术中评估结果进行比较。
结果
43例患者中有38例（88%）术前动态超声检查结果与术中发现一致。43例患者中有5例（12%）尺神经稳定性的体格检查结果与术中发现一致。在43例动态超声检查结果与原位减压后尺神经稳定程度不相关的病例中，有4例动态超声检查高估了尺神经的稳定程度。
结论
术前动态超声可用于准确预测原位减压后尺神经不稳定的程度。
研究类型/证据水平：诊断性研究II级。
