“…Phantoms simulating specific body parts can be simulated by immersing structures in a gelatin solution. [11,13,16,19] To simulate human soft tissue, materials such as flour, mutacil, graphite powder, and psyllium husk can be added to the solution. In the present study, the outer container for our cervical spine phantom was removed before use; we therefore used a gelatin to psyllium husk ratio of 3.3:1 to increase durability and prevent damage from ultrasound transducers.…”

“…Only a few studies have fabricated cervical spine phantoms. [15,16,26] In a study by Lerman et al, [15] a phantom for cervical transforaminal injection was developed. Although they simulated vertebral arteries in the spine phantom, the use of polyvinyl-chloride plastic material necessitated a well-ventilated area, as well as the use of protective eyewear and gloves for safety.…”

“…Although they simulated vertebral arteries in the spine phantom, the use of polyvinyl-chloride plastic material necessitated a well-ventilated area, as well as the use of protective eyewear and gloves for safety. In a report by van Eerd et al, [16] a plastic cervical spine was placed in a pre-made polycarbonate cylinder that was relatively difficult to fabricate. Although it was similar to the phantom used in the present study, it did not simulate soft tissue with materials such as psyllium husk; furthermore, the authors did not evaluate its utility for education and training.…”

Background:Few studies have been conducted on the utility of cervical spine phantoms for practicing cervical procedures. Here, we describe a simple method for creating a cervical spine phantom and investigate whether the use of a gelatin-based phantom is associated with improved proficiency in performing ultrasound-guided cervical medial branch block.Methods:A cervical spine phantom was prepared using a cervical spine model immersed in a mixture of gelatin and psyllium husk. In total, 27 participants, inexperienced in spinal ultrasonography, were enrolled and allocated to 1 of 2 groups (training group, n = 18; control group, n = 9). All participants were tested (test-1) following an introductory course of basic ultrasonography. Participants in the control group were tested again after 1 week (test-2). Those in the training group received a further individual 3-hour training session, and were tested again after 1 week (test-2).Results:The mean performance score in test-1 was 62.5 ± 10.1 points in the training group and 62.3 ± 4.1 points in the control group [95% confidence interval (95% CI) −5.5 to 5.8; P = .954]. In test-2, the mean score was 86.8 ± 6.5 points and 59.9 ± 4.4 points in the training and control groups, respectively (95% CI 21.9–31.8; P < .001). The mean time required to complete test-1 was 84.6 ± 26.6 seconds in training group and 90.7 ± 43.9 seconds in the control group (95% CI −34.0 to 21.7; P = .653); in test-2, the time required was 56.6 ± 27.9 and 91.2 ± 43.8 seconds (95% CI −63.0 to −6.2; P = .019), respectively. Interobserver reliability showed excellent agreement based on the intraclass correlation coefficient, and moderate to almost perfect agreement by kappa statistics.Conclusion:Training using a gelatin-based cervical spine phantom helps novices acquire the skills necessary to perform ultrasound-guided cervical medial branch blocks.

“…The absence of the anterior tubercle of the C7 transverse process and prominence of those of the C6 transverse process (Chassaignac tubercle) are used as anatomic landmarks for the identification of the cervical vertebra level ( Fig. 20 ) ( 62 ). The transverse process of C2-5 can be identified as successive steps cranial to the C6 level.…”

Ultrasonography-Based Thyroidal and Perithyroidal Anatomy and Its Clinical Significance

2015

Ultrasonography (US)-guided procedures such as ethanol ablation, radiofrequency ablation, laser ablation, selective nerve block, and core needle biopsy have been widely applied in the diagnosis and management of thyroid and neck lesions. For a safe and effective US-guided procedure, knowledge of neck anatomy, particularly that of the nerves, vessels, and other critical structures, is essential. However, most previous reports evaluated neck anatomy based on cadavers, computed tomography, or magnetic resonance imaging rather than US. Therefore, the aim of this article was to elucidate US-based thyroidal and perithyroidal anatomy, as well as its clinical significance in the use of prevention techniques for complications during the US-guided procedures. Knowledge of these areas may be helpful for maximizing the efficacy and minimizing the complications of US-guided procedures for the thyroid and other neck lesions.

Introduction:The evaluation of cervical-spine in a major trauma patient needs a bedside efficient tool to rule out cervical spine injury as the role of X-ray and Computed Tomography (CT) in this setting is limited. Point of care ultrasonography (POCUS) is being used as an adjunct during trauma resuscitation. The aim of this study was to evaluate the use of POCUS for identifying cervical spine injuries. Methods: We recruited 84 cases with cervical spine injury based on CT scan after taking consent. POCUS was used as per the operational definition of study methods while maintaining manual in-line stabilisation. Statistical analysis was done by using STATA version 14. Results: Normal cervical anatomy was visible through anterior approach in POCUS except for the 1 st and 2 nd cervical vertebrae. The sensitivity and specificity of POCUS vs CT scan for vertebral body listhesis were 84.52% (95% CI of 0.65-0.95) and 89.66% (95% CI 0.78-0.96) with p-value <0.0001. Sensitivity and specificity of POCUS vs CT for vertebral body fracture were 40.91% (95% CI of 0.20-0.63) and 96.77% (95% CI of 0.88-0.99) with p-value <0.0001. The overall sensitivity and specificity of POCUS were 45.83% and 83.33% (p = 0.06) and excluding isolated posterior column injuries, sensitivity and specificity were 70.21% and 83.33% (p < 0.05). Conclusion: POCUS identified injuries such as fracture and listhesis. Because of high rate of missed injuries, ultrasound at present cannot be used as a screening or diagnostic tool for decision-making in cervical spine injury.
