BACKGROUND: To compare the analgesic effect of ISB with a combination of ISB-SSNB and patients who were given opioids with PCA without block in adult patients undergoing shoulder surgery, as measured by opioid consumption and pain intensity in the first 24 hours postoperatively. METHODS: Ninety patients who underwent shoulder surgery were randomly divided into three groups. Group I in which ISB was performed and patient-controlled analgesia (PCA) was inserted, Group II with; ISB and SSNB combined, and PCA was inserted, and Group III where; only PCA was used...

BACKGROUND: Distal suprascapular nerve blocks (SSNB) can be performed at the level of the suprascapular notch (the preferred site) or at the level of the spinoglenoid notch. OBJECTIVES: To compare the efficacy and safety of spinoglenoid versus suprascapular notch approaches for ultrasound (US)-guided distal SSNB in patients with chronic shoulder pain. STUDY DESIGN: Prospective randomized controlled trial. SETTING: Outpatient physical medicine and rehabilitation outpatient clinic of a tertiary center...

BACKGROUND: Neuralgic amyotrophy (NA) is a monofocal or oligofocal inflammatory neuropathy whose incidence has been significantly underestimated. A connection between constrictions and torsions of peripheral nerves with this disease has been increasingly established in recent years. Modern imaging techniques such as high-resolution nerve ultrasound and MR neurography have contributed to a better understanding of the pathophysiology and a better assessment of the prognosis of the disease...

A common animal model of muscle pathology following rotator cuff tear (RCT) is a tenotomy of the supraspinatus and infraspinatus, often combined with neurotomy of the suprascapular nerve, which induces a more robust atrophy response than tenotomy alone. However, the utility of this model depends on its similarity to human muscle pathology post-RCT, both in terms of the disease phenotype and mechanisms of muscle atrophy and fatty infiltration. Given the clinical prevalence of nerve injury is low and the muscular response to denervation is distinct from mechanical unloading in other models, an understanding of the biological influence of the nerve injury is critical for interpreting data from this RCT model...

BACKGROUND: Spontaneous resolution of a spinoglenoid notch ganglion cyst (SGC) without surgical treatment has been rarely reported; however, we have encountered this phenomenon occasionally. Therefore, we aimed to describe a case series of consecutive patients with SGC in whom it spontaneously resolved without surgical treatment. METHODS: We retrospectively reviewed 12 patients with magnetic resonance imaging (MRI)-confirmed SGC in whom it resolved without surgical treatment between January 2011 and March 2023...

A complication of peripheral nerve injuries, of which there exists limited discourse, is the entrapment of the nerve as it regenerates from the site of injury to its end target, resulting in the arrest of axon regeneration and a consequent reduction of functional recovery. This proof-of-concept paper reports a review of the relevant literature alongside a case series of patients who presented with this phenomenon and who were treated with targeted peripheral nerve decompression. Three cases were identified prospectively...

Reverse total shoulder arthroplasty (RTSA) is a widely employed surgical intervention for managing advanced shoulder arthritis. Postoperatively, patients frequently experience intense pain, particularly within the first 48 hours. Effective pain management through regional analgesia not only facilitates a quicker hospital discharge but also minimizes the reliance on opioids. One such regional analgesic approach is the combined suprascapular and axillary nerve block, which targets the glenohumeral joint, rotator cuff muscles, and the shoulder's lateral region for effective pain alleviation...

OBJECTIVE: Shoulder dislocation represents a prevalent category within joint dislocation, accounting for about 40% of all joint dislocations, and anterior dislocation stands out as the prevailing type. It has been reported that in 1.6% of patients, the Latarjet procedure performed under arthroscopy involves transferring the coracoid process to the anterior-inferior aspect of the glenoid and fixing it with two bicortical screws. The tip of the screws may impinge the suprascapular nerve located behind the scapula, resulting in shoulder pain and weakness...

Background: In brachial plexus surgery, a key focus is restoring shoulder abduction through spinal accessory nerve (SAN) to suprascapular nerve (SSN) transfer using either the anterior or posterior approach. However, no published randomised control trials have directly compared their outcomes to date. Therefore, our study aims to assess motor outcomes for both approaches. Methods: This study comprises two groups of patients. Group A: anterior approach (29 patients), Group B: Posterior approach (29 patients)...

OBJECTIVES: The primary objective of this study was to compare pain intensity after pulsed radiofrequency (RF) or suprascapular nerve block for the treatment of chronic shoulder pain. The secondary objectives were to compare the shoulder range of motion and supplementary analgesic requirement. METHODS: This randomized and prospective study included 40 patients, with chronic shoulder pain allocated into 2 groups. One group underwent pulsed RF, and the other group was submitted to block (B) of the suprascapular nerve, guided by ultrasound...

INTRODUCTION: The shoulder is one of the joints most affected by osteoarthritis, with a prevalence of almost 20% in adults over 65 years of age. Various treatments have been proposed to control osteoarthritis pain, including radiofrequency, pulsed and thermal, and recently cryoanalgesia. We propose in this series of cases a new approach to analgesic therapy with chemical denervation with phenol. MATERIALS AND METHOD: Patients who underwent phenolysis for shoulder osteoarthritis at our institutions in Italy and Australia between August 2022 and May 2023 were included...

Anterior shoulder dislocation (ASD) is the most common type of dislocation presented to the emergency department (ED) with severe pain and limitation of range of movement. Procedural sedation and analgesia are commonly used for ASD, but regional techniques are gaining popularity. Interscalene brachial plexus block is effective but has several limitations. Suprascapular nerve block (SSNB) has been explored for this indication. The SSNB is commonly performed using the posterior approach in a sitting position and can be technically difficult in dislocated patients...

INTRODUCTION: The supraspinatus muscle tendon is the most frequently rotator cuff muscle torn. Reliable shoulder pain relief strategies are needed for patients with severe pain, refractory to conservative management, and without surgical indication. MATERIALS AND METHODS: We conducted a retrospective analysis in a Portuguese reference Rehabilitation Centre during the 1st of January 2020 and the 30th of June 2021, including all patients with partial or complete supraspinatus tendon tear, older than 50 years, who presented with severe pain and who were submitted to suprascapular nerve pulsed radiofrequency...

BACKGROUND AND OBJECTIVES: Paralysis after spinal cord injury involves damage to pathways that connect neurons in the brain to peripheral nerves in the limbs. Re-establishing this communication using neural interfaces has the potential to bridge the gap and restore upper extremity function to people with high tetraplegia. We report a novel approach for restoring upper extremity function using selective peripheral nerve stimulation controlled by intracortical microelectrode recordings from sensorimotor networks, along with restoration of tactile sensation of the hand using intracortical microstimulation...

BACKGROUND: The suprascapular nerve (SSN) is an important nerve that contributes to shoulder joint sensation and movement. The anterior suprascapular nerve block (aSSNB) has the potential for noninferior analgesic effect compared with the interscalene block while preserving respiratory function. This study investigated the median effective volume (MEV) of 0.375% ropivacaine in aSSNB for analgesic effect among patients undergoing arthroscopic shoulder surgery. OBJECTIVES: Our primary objective was the MEV...

BACKGROUND: The gold standard postoperative analgesia protocol for arthroscopic rotator cuff repair procedures is the interscalene block (ISB), which prevents the significant consequences of phrenic nerve block associated with hemidiaphragmatic paralysis (HDP). The infraclavicular brachial plexus block (BPB) combined with the suprascapular nerve block (SSNB) had the same analgesic efficacy as the infraclavicular BPB alone, with no effect on respiration. OBJECTIVES: Therefore, the study aimed to assess the HDP and analgesic efficacy of both approaches in controlling pain following arthroscopic rotator cuff repair surgeries...

This study aimed to investigate how the presence of neuropathic pain related to partial rotator cuff tears affects the short-term results of subacromial injection and suprascapular nerve blockade therapy in patients with chronic shoulder pain. In this prospective observational study, shoulder pain via verbal numeric pain rating (VNPR, 0-10) and functional status through simple shoulder test (SST) were evaluated before and second week after procedure. After dividing as neuropathic pain and non-neuropathic pain groups, pre-procedural and follow-up scores concerning pain intensity, functional status, and whether there were those of patients with minimal clinically important change (MCIC) in areas of pain and function were evaluated...

BACKGROUND: In some large to massive rotator cuff tears (RCTs), fatty degeneration (FD) is more severe in the infraspinatus than the supraspinatus muscle, and in such cases, suprascapular neuropathy is highly suspected. Nerve release at the suprascapular notch might alleviate this problem. PURPOSE: To evaluate the effects of the transverse scapular ligament (TSL) release in patients with large to massive RCTs with more severe FD of the infraspinatus than the supraspinatus...

Arthroscopic rotator cuff repair is one of the most painful surgical procedures; patients complain of pain especially during the first 48 hours postoperatively. Pain management is an essential goal to reduce the demand for analgesic agents and patient discomfort. Various methods have been introduced for arthroscopic rotator cuff repair, including continuous arthroscopy-guided suprascapular nerve blocks (SSNB) and interscalene nerve blocks. However, the aforementioned procedures have shown disadvantages such as catheter mobilization, which may cause injury to the artery, a weak analgesic effect, and Horner syndrome, as well as phrenic nerve paralysis...
