Ultrasound-guided injection acupotomy as a minimally invasive intervention therapy for cervical spondylotic radiculopathy: a randomized control trial

OBJECTIVE

To explore the efficacy and safety of ultrasound-guided injection acupotomy as a minimally invasive intervention treatment of cervical spondylotic radiculopathy (CSR).

METHODS

160 CSR subjects were recruited who met the inclusion criteria in our hospital from October 2019 to December 2021. The subjects were randomly divided into the experimental and control group, with 80 cases in each. The experimental group received ultrasound-guided injection acupotomy as a minimally invasive intervention therapy. The control group received ultrasound-guided selective nerve root block (SNRB). The Odom's criteria clinical curative effect, visual analogue scale (VAS), neck disability index (NDI), and 36-Item Short Form Health Survey questionnaire (SF-36) were used to evaluate the outcome of subjects at several different points in time.

RESULTS

At 30 min and 1 month after the end of treatment, there was no significant difference in any scores. However, after six months, the excellent and good rate was better in the experimental group compared to the control (RD = 0.175; 95% CI, 0.044-0.300, p = 0.009). The total effective rate was also better in the experimental group (RD = 0.126; 95% CI, 0.021-0.232, p = 0.018). In contrast, the VAS score (MD = -0.500; 95% CI, -1.000-0.000, p = 0.030) and NDI score (MD = -6.460; 95% CI, -11.067 to -1.852, p = 0.006) were lower in the experimental group compared to the control. The total SF-36 score was higher in the experimental group (MD = 7.568; 95% CI, 2.459-12.677, p = 0.004).

CONCLUSION

Ultrasound-guided injection acupotomy minimally invasive interventional treatment of CSR has no significant difference in short-term curative effect compared with ultrasound-guided SNRB, but the data indicators are significantly better than the latter at 6 months after the end of the course of treatment, showing better long-term efficacy.

Value of ultrasound in the anatomical evaluation of the brachial plexus: correlation with magnetic resonance imaging

Objective

To assess the accuracy of ultrasound in the visualization of the brachial plexus and to determine the value of the method in comparison with that of magnetic resonance imaging (MRI).

Materials and Methods

This was an anatomical study of the brachial plexuses of 20 asymptomatic adults (40 plexuses), comparing ultrasound and MRI in terms of their accuracy. In the ultrasound study, a high-frequency linear transducer was used, and a neurovascular coil was used in the MRI study. To estimate the frequency of visualization, the brachial plexus was divided into segments.

Results

The cervical nerve roots, the upper trunk, and the middle trunk were the segments that were best visualized on ultrasound. On MRI, the degree of visualization was excellent for most of the segments. In the comparison between ultrasound and MRI, the C6, C7, upper trunk, and middle trunk segments showed equivalent degrees of visualization, with a high level of agreement between the two methods.

Conclusion

In the brachial plexus, ultrasound can be used in the assessment of the cervical nerve roots, as well as of the upper and middle trunks, although it provides limited visualization of the remaining segments. Ultrasound and MRI showed a high level of agreement for the visualization of the C6, C7, and middle trunk segments.

Localized cervical pain: advantages and limits of ultrasound evaluation

PURPOSE

Cervical pain is very frequent in the general population. In clinical practice, plain X-ray and, in selected cases, computed tomography or magnetic resonance imaging, are performed. However, the feasibility and utility of ultrasound examination have been poorly investigated. Aim of the present study was to evaluate whether ultrasound could be useful in the diagnosis of localized cervical pain.

METHODS

Subjects suffering from posterior cervical pain without irradiation to surrounding tissues were enrolled. After clinical and functional evaluation (demographic and anthropometric data, VAS at rest and during neck movements, symptoms duration, and characteristics of pain onset [atraumatic or traumatic]), an ultrasound exam of the cervical spine was performed according to standard protocols.

RESULTS

The anatomic structures of the neck district were visualized in 124/127 enrolled patients and pathological features were observed in 58. Significant ultrasound differences were registered between the patients with traumatic and atraumatic onset of neck pain. In the first group, articular effusion, capsular bulging, disalignment and avulsion of the articular apex were observed, whereas in the latter cortical irregularities, osteophytosis, and articular ankylosis were prevalent.

CONCLUSIONS

Ultrasound examination can be used as diagnostic tool in the evaluation of selected patients suffering from localized cervical pain, particularly in cases of pain due to traumatic injuries.
