Objective This study aims to determine the methods of percutaneous release procedures in the lumbar ligamentum flavum (LF) under ultrasound guidance by acupotomy and provide an anatomical basis for intrusive treatment of lumbar disc herniation and lumbar spinal canal stenosis. Methods Twelve cadavers including 4 females and 8 males aged 60 to 90 years (73.42 ± 14.57 years), without formalin fixation, were selected. Guided by an ultrasound transducer, we punctured acupotomy to release lumbar LF in L3/L4, L4/L5, and L5/S1 segments. In the transverse-axis approach, the probe was placed transversely, while in the longitudinal-axis approach, the probe was placed longitudinally. The depth of needle penetration (A), the distance between the puncture point and spinous process (B), and the distance between the puncture point and sacral cornu (C) were measured on cadavers, and the depth of needle penetration (U-A), the distance between the puncture point and spinous process (U-B), and the angle for acupotomy (D) on ultrasound images were also measured. Statistical analyses were carried out using SPSS. Paired sample t-tests and homogeneity of variance tests and one-way analysis of variance (ANOVA) were performed. The Pearson correlation coefficients and linear correlation coefficients were calculated for the data obtained from ultrasound and cadaver measurements. Results No obvious blood vessels and nerves were observed in the puncture path, and the spinal dura was intact. There was no statistical difference between the left and right side measurements obtained from the ultrasound images and the cadavers. The penetration depth in the transverse-axis approach was less than that in the longitudinal-axis approach, and the angle of the needle in the transverse-axis approach was greater than that in the longitudinal-axis approach. The measured data for the transverse-axis approach for L3/L4, L4/L5, and L5/S1 segments showed that there were no differences in the needle angle, the depth of needle penetration, and the distance from the spinous process to the puncture point among the three segments. There was a strong correlation between the depth of needle penetration and the distance from the spinous process to the puncture point on the ultrasonic images and the cadavers on the path of acupotomy. Linear equation A = 2.02 + 0.83 ∗ U-A, R2 = 0.352; B = 1.37 + 0.71 ∗ U-B, R2 = 0.252, where A/B refers to the data measured on the cadavers and U-A/U-B refers to the data measured on the ultrasound images. Conclusion In this study, ultrasound guidance was applied, which better guaranteed the safety and feasibility of acupotomy therapy. Before performing the treatment, the depth of needle penetration in the human body can be determined by measuring the distance between the needle point and the target position on the ultrasound image. Under ultrasound guidance, the transverse-axis approach has a smaller puncture depth and greater puncture angle than the longitudinal-axis approach. Hence, this study believes that the transverse-axis approach ...
ObjectiveThis study aimed to determine the safety and accuracy of ultrasound-guided acupotomy percutaneous loosening of the transverse carpal ligament.MethodsThe 100 upper limb specimens were equally divided into the ultrasound-guided acupotomy group (U) and the nonultrasound-guided acupotomy group (N). For the U group, we simulated ultrasound-guided acupotomy loosening of the transverse carpal ligament in a human specimen, and for the N group, we performed the loosening of the transverse carpal ligament through the same approach under nonultrasound-guided conditions. The safety and accuracy of the two methods were compared through measurement.ResultsIn the ultrasound-guided group, the injury rate of nerves, blood vessels and tendons caused by needle-knife release was 0%. In the non-ultrasound-guided group, the rate of nerve, blood vessel and tendon damage was 6 percent, 12 percent and 20 percent, respectively. χ2 test (Fisher exact test) was performed for the nerve and blood vessel damage rates in the two groups (PN > 0.05, PA < 0.05), the difference in nerve damage rates was not statistically significant, but the difference in blood vessel damage rates was statistically significant. Pearson's χ2 test was performed on the tendon injury rates of the two groups (PF < 0.05), and the difference was statistically significant. In the ultrasound-guided group, the proportion of acupotomy marks greater than or equal to half of the width of the transverse carpal ligament was 86%, and the non-ultrasound-guided group was 36%. The accuracy of the two surgical methods was tested by Pearson's χ2 test (PL < 0.05), and the difference was statistically significant. According to the measurement, the ultrasound-guided acupotomy technology had high safety and accuracy.ConclusionIn this study, we designed a new method for cutting the transverse carpal ligament under ultrasound guidance, which is different from surgery. These results indicate that this is a safe and accurate method of interventional treatment of carpal tunnel syndrome.
Background:Acupotomy is a miniature surgery instrument. It can cut and detach the abnormal, cicatricial, and contractured tissues by causing only microtrauma. Acupotomy has been widely used clinically with a satisfactory efficacy. With the development of ultrasound technology, ultrasound-guided acupotomy has shown great value in clinical practice. But it is not yet clear that ultrasound-guided acupotomy is very effective and safe. Therefore, it is important to re-evaluate the available evidence to reach a relatively convincing conclusion that acupotomy by ultrasound-guided technique is a better choice than traditional acupotomy. The purpose of this systematic review is to provide a method for evaluating the effectiveness and safety of acupotomy by ultrasound-guided technique.Methods:This systematic review will be performed by searching relevant randomized controlled trials (RCTs) without any language or publication status restriction from inception to December 2019 by 2 researchers in nine databases (PubMed, Medline, Embase, Cochrane Library, Chinese literature databases, Chinese Biomedical Literature Database [CBM], China National Knowledge Infrastructure [CNKI], China Science and Journal Database [CSJD], and Wanfang Database). All RCTs evaluating acupotomy by the ultrasound-guided technique will be included in this study. Visual analog scale (VAS) and change of symptom will be assessed as the primary outcomes. The change in the ultrasound image, safety and adverse events, and acceptability will be assessed as secondary outcomes. The selection of study, data collection and analysis, and assessment of the study quality will be completed independently by 2 researchers. RevMan v.5.3 will be used for meta-analysis if no significant heterogeneity is detected. Continuous outcomes will be presented as the mean difference (MD) or standardized MD, while dichotomous data will be expressed as the relative risk.Results:This study will provide a high-quality synthesis of QL and AR to assess the effectiveness and safety of acupotomy by ultrasound-guided technique.Conclusion:This systematic review will provide evidence to judge whether acupotomy by ultrasound-guided technique is an effective the efficacy and safety intervention.PROSPERO registration number:CRD42018109070.
Rationale:Tendinitis of the longus colli muscle is an aseptic inflammatory process leading to acute posterior neck pain, neck stiffness, and dysphagia or odynophagia. We present a patient exhibiting an infrequent symptom, vertigo. This is the first description of the occurrence of vertigo symptoms caused by longus colli tendinitis.Patient concerns:A 38-year-old man was diagnosed with vertigo, presenting with a 1-month history of dizziness, palpitations, and numbness in the hands.Diagnosis:Longus colli tendinitis. The diagnosis was established using magnetic resonance imaging fat-suppression sequences.Interventions:Treatment with corticosteroid injections and acupotomy.Outcomes:The symptoms relieved immediately after the treatment and complete resolution of the symptoms was observed after 1 week.Lessons:Longus colli tendinitis with vertigo is an under-reported condition in the literature and physicians should be aware of its existence. A lack of familiarity with the anatomy of the prevertebral space and its variable radiographic appearance makes the diagnosis of longus colli tendinitis clinically difficult. Misdiagnosis of this condition may lead to unnecessary interventions in vertigo.
