“…Besides, the technique using the inferior belly of the omohyoid muscle as the landmark of SSN identification has been described (Battaglia et al). The possibility of SSN visualization using this technique was 90-96 % (Rothe et al;Ko et al, 2017). These previously reported results were similar to our study in that the SSN at the supraclavicular region was correctly identified in 90 % of cases.…”

Sonographic identification of suprascapular nerve (SSN) is essential for diagnosis of suprascapular neuropathy and ultrasound-guided suprascapular nerve block. This study aims to demonstrate the accuracy of identification of SSN at supraclavicular region by ultrasonography in fresh cadavers. Ninety-three posterior cervical triangles were examined. With ultrasonography, SSN emerging from the upper trunk of brachial plexus was identified and followed until it passed underneath the inferior belly of omohyoid muscle. Sonographic visualization of SSN in supraclavicular fossa was recorded. Then, cadaveric dissection was performed to determine the presence or absence of SSN. An agreement between sonographic identification and direct visualization was specified and categorized the following three patterns: "correctly identified" (pattern I), "incorrectly identified" (pattern II), and "unidentified" (pattern III). The identification of SSN using sonography was correct in almost 90 %. The diameter of SSN with pattern I was the largest compared to those of other two patterns. In pattern I, SSN ran laterally from the upper trunk of brachial plexus and passed underneath the inferior belly of omohyoid muscle. Therefore, SSN was easily identified under ultrasonography. In pattern II, nerve identified by ultrasonography was literally the dorsal scapular nerve.In pattern III, SSN was unable to be identified because of its anatomical variation. The accuracy of ultrasonographic identification of SSN at supraclavicular fossa is high and the key sonoanatomical landmarks are the lateral margin of brachial plexus and the inferior belly of omohyoid muscle. The anatomical variants of SSN are reasons of incorrect or unable identification of SSN under ultrasonography.

Background Frozen shoulder is an incapacitating disease that causes pain and limitation in the shoulder joint functional capacity. This work aimed to assess the efficacy of ultrasound-guided combined intra-articular corticosteroids (CS) injection and suprascapular nerve block (SSNB) in pain control in patients with frozen shoulders. Results Our prospective study included 40 patients, equally divided into two groups: group A; managed with combined ultrasound (US) guided intra-articular corticosteroids injection (IACSI) and SSNB, and group B patients managed with US-guided SSNB. The visual analog scale score statistically significantly improved after both injections. This success was maintained and showed mild improvement at 8-week intervals (with increased patient capability to do physiotherapy after pain control). Similarly, improvement in the functional capacity of the shoulder joint was identified and assessed by the Oxford shoulder score (OSS) in both groups. Mean OSS was statistically significantly higher at 4-week intervals than before the nerve block for groups A and B. At 8 weeks interval, this favorable result was sustained (p < .001). Conclusions US-guided SSNB is an effective, radiation-free method to alleviate frozen shoulder-related pains. However, US-guided combined SSNB and IACSI was more effective than SSNB alone in both pain alleviation and improved shoulder joint function.
