“…[10] The technique for SSNB has been described since 1941, with several definitions and variations throughout the years. [16] Due to decreased pain levels achieved by SSNB, an effective rehabilitation exercise program can be performed. [17] The SSNB has been used for management of acute or chronic pain in shoulder.…”

Objectives: This study aims to compare the superiority of different suprascapular nerve block (SSNB) application methods on hemiplegic shoulder pain (HSP), in a blinded and stimulator guided manner. Patients and methods:Twenty-six stroke patients (19 males, 7 females; mean age 61.0±9.4 years; range 53 to 76 years) meeting the enrollment criteria, were included in this study between September 2014 and November 2014. Patients were randomly divided into two equal groups. Patients in group A received blinded SSNB and patients in group B received stimulator guided SSNB. Range of motion (ROM) (by goniometer) and pain levels (by visual analog scale-VAS) were assessed. Evaluations were made before, one hour after and one week after SSNBs. Results:In each group, VAS pain scores significantly decreased over time (p<0.0001) and a significant increase in terms of flexion and abduction ROM angles (group A: p=0.002 and p=0.010; group B: p=0.004 and p=0.012, respectively) was observed. In addition, internal rotation ROM angles were found to have increased in group B (p=0.036). There were no significant differences in ROM and VAS one hour and one-week change scores between the two groups (p>0.05). Conclusion:Both blinded or stimulator guided suprascapular nerve block techniques were safe and effective for pain relief in hemiplegic shoulder pain management. None of the injection techniques was superior to the other.Keywords: Blinded; hemiplegic shoulder pain; stimulator guided; suprascapular nerve block.Hemiplejik omuz ağrısında kör ve stimülatör kılavuzluğunda supraskapular sinir blokajının karşılaştırılması: Pilot çalışma ÖZ Amaç: Bu çalışmada hemiplejik omuz ağrısında (HOA) kör ve stimülatör kılavuzluğunda, farklı supraskapular sinir blokajı (SSSB) uygulama yöntemlerinin birbirlerine üstünlüğü araştırıldı. Hastalar ve yöntemler:Eylül 2014 -Kasım 2014 tarihleri arasında yapılan bu çalışmaya katılma kriterlerini karşılayan 26 inme hastası (19 erkek, 7 kadın; ort. yaş 61.0±9.4 yıl; dağılım 53-76 yıl) dahil edildi. Hastalar randomize olarak iki eşit gruba ayrıldı. Grup A'daki hastalara kör SSSB, grup B'deki hastalara ise stimülatör kılavuzluğunda SSSB verildi. Eklem hareket açıklığı (EHA) (gonyometre ile) ve ağrı düzeyleri (görsel analog ölçeği-GAÖ ile) değerlendirildi. Ölçümler SSSB öncesinde, bir saat sonrasında ve bir hafta sonrasında yapıldı. Bulgular:Her iki grupta GAÖ ağrı skorlarında zamanla anlamlı olarak azalma (p<0.0001); fleksiyon ve abdüksiyon EHA açılarında (sırasıyla grup A: p=0.002 ve p=0.010; grup B: p=0.004 ve p=0.012) ise anlamlı artış gözlendi. Ek olarak grup B internal rotasyon EHA açılarında artış saptandı (p=0.036). Gruplar arasında, GAÖ ve EHA açıları bir saatlik ve bir haftalık değişim skorlarında anlamlı bir farklılık yoktu (p>0.05).Sonuç: Kör ya da stimülatör kılavuzluğunda yapılan supraskapular sinir blokajı tekniklerinin her ikisi de güvenli ve hemiplejik omuz ağrısı tedavisinde ağrının giderilmesinde etkilidir. Hiçbir enjeksiyon tekniği diğerinden üstün değildir.Anahtar sözcükler: Kör; hemiple...

“…With different approaches, the SSN can be targeted at either the suprascapular notch 1,7 or the suprascapular fossa. 8,9 Major disadvantages of targeting the SSN at the notch are the potential risk of pneumothorax, intravascular injection, injury, or misplacement.…”

Purpose Previous work on the ultrasound-guided injection technique and the sonoanatomy of the suprascapular region relevant to the suprascapular nerve (SSN) block suggested that the ultrasound scan showed the presence of the suprascapular notch and transverse ligament. The intended target of the ultrasound-guided injection was the notch. The objective of this case report and the subsequent cadaver dissection findings is to reassess the interpretation of the ultrasound images when locating structures for SSN block. Clinical features A 45-yr-old man with chronic shoulder pain received an ultrasound-guided SSN block using the suprascapular notch as the intended target. The position of the needle was verified by fluoroscopy, which showed the tip of the needle well outside the suprascapular notch. Similar ultrasound-guided SSN blocks were performed in two cadavers. Dissections were performed which showed that the needle tips were not at the suprascapular notch but, more accurately, were close to the SSN but at the floor of the suprascapular fossa between the suprascapular and spinoglenoid notch. Conclusion Our fluoroscopic and cadaver dissection findings both suggest that the ultrasound image of the SSN block shown by the well-described technique is actually targeting the nerve on the floor of the suprascapular spine between the suprascapular and spinoglenoid notches rather than the suprascapular notch itself. The structure previously identified as the transverse ligament is actually the fascia layer of the supraspinatus muscle.

“…The block does not result in any skin analgesia, but when successful, relieves pain in the shoulder joint. The S.S. nerve block had been well described since several decades [12] and Granirer firstly described a posterior approach [13,14]. Our procedures are usually performed under ultrasound guidance but to refine our technique and reduce the risk of pneumothorax we followed the indirect S.S.N.B.…”

Background: Neural blockade is widely used in clinical practice to alleviate acute or chronic pain, including pain during rehabilitation. To date there is little controlled evidence to confirm the efficacy of nerve blocks in hemiparetic shoulder pain after stroke. Design: This study is a prospective, open label, cohort trial reporting result from a cohort of stroke patients affected by shoulder pain. Aim: As a cohort study report, in which it is often firstly reported the possibility of an association between an observed effect and a specific environmental based on detailed clinical evaluations and histories, we aim to firstly provide clues in identifying Suprascapularis Nerve blockade as further valuable approach for shoulder pain after stroke. Population: We studied a cohort of patients affected by hemiparetic shoulder pain after Stroke. Methods: Our protocol foresees nerve blocks to be performed each 3 out of 4 days (treatment lasting 30 days) in conjunction with a rehabilitation program with the first aim to provide the window of opportunity to proceed with effective rehabilitation. 47 potential study subjects fulfilled the study criteria and were enrolled. Twenty-four subjects were randomised to the study Group to receive SSNB for the pain of their hemiparetic shoulder while 23 subjects randomized to the control Group whose member did not receive SSNB. They received serial blocks each 3 out of 4 days during rehabilitation. Results: Both treatment reported a reduction in the intensity of their shoulder pain, according to data collected from day 1 through day 42 (6 weeks). Study Group patients, receiving SSNBs, reported significant improvement from entry through the whole follow-up period. The efficiency data were higher for SSNB Group after 2 weeks and again for SSNb group at the end of treatment. Conclusion: Excellent pain relief was achieved in SSNB without clinically relevant complications, these patients having a better improvement on pain during rehabilitation, than the control subjects. Great efficacy has been achieved by combining a nerve block and rehabilitation. About Clinical Rehabilitation Impact, we believe that Suprascapularis nerve blocks can help the stroke survivors maintain an ambulatory or outpatient treatment status, maintain participation in a physical therapy or rehabilitation program, decrease the need for analgesics and in some cases lead to a complete pain relief.
