PURPOSE: The aim of the study was to evaluate the assessability of the suprascapular nerve (SSN) by ultrasonography in cadavers and healthy volunteers. MATERIALS AND METHODS: With ultrasonography guidance, needles were placed at origin of the SSN of four cadavers and evaluated by dissection. Two blinded radiologists performed 60 ultrasonography scans in 30 healthy volunteers to study the entire SSN at five anatomical landmarks. RESULTS: Dissection revealed that the needles were correctly located at the nerve's origin...

BACKGROUND: Suprascapular nerve (SSN) entrapment is usually ascribed to static or dynamic compression. When no cause of compression is found, SSN entrapment is defined as idiopathic. Focal hourglass-like constriction (H-LC) of the SSN that results in muscle paralysis represents an unusual condition that may be misinterpreted and erroneously diagnosed as SSN entrapment or as neuralgic amyotrophy. METHODS: With the aim of finding clinical and surgical clues that could differentiate the traditional form of idiopathic SSN entrapment from the rare H-LC, a series of 6 cases of SSN palsy caused by H-LC is presented...

Xiaotian Jia, Chao Chen, Lin Chen, Cong Yu, Tadashi Kondo
RATIONALE: Malignant granular cell tumor is a kind of rare and highly aggressive malignant tumor that commonly occurs in lower extremity, trunk, and peritoneal cavity. Huge malignant granular cell tumor (MGCT) with suprascapular nerve and brachial plexus invasion was extremely rare. PATIENT CONCERNS: We present a special case of a 48-year-old orthopedist who suffered from MGCT. The orthopedist had regarded that he suffered from scapulohumeral periarthritis. DIAGNOSES: The disease was noticed until a painless mass on his right neck was discovered 9 months later...

Neurogenic thoracic outlet syndrome is caused by a neurologic compression of the brachial plexus before it reaches the arm. Three anatomic areas are common locations for such an entrapment because of their congenital and/or acquired tightness: the interscalene triangle, the costoclavicular space, and the retropectoralis minor space. Because the compression level usually remains unknown, the treatment is still controversial and most teams focus on only one potential site. We propose an all-endoscopic technique of complete brachial plexus neurolysis that can be divided into three parts, one for each entrapment area...

BACKGROUND: Interscalene block provides optimal shoulder surgery analgesia, but concerns over its associated risks have prompted the search for alternatives. Suprascapular block was recently proposed as an interscalene block alternative, but evidence of its comparative analgesic effect is conflicting. This meta-analysis compares the analgesic effect and safety of suprascapular block versus interscalene block for shoulder surgery. METHODS: Databases were searched for randomized trials comparing interscalene block with suprascapular block for shoulder surgery...

PURPOSE: The purpose of this study was to compare the risk of glenoid perforation during SLAP repair for suture anchors placed through an anterolateral portal versus a posterolateral portal of Wilmington. METHODS: Ten bilateral cadaveric shoulders were randomized to suture anchor placement through an anterolateral portal on one shoulder and a posterolateral portal on the contralateral shoulder. Anchors were placed into anterior, posterior, and far posterior positions on the glenoid rim (1 o'clock, 11 o'clock, and 10 o'clock positions for right shoulders)...

Both arthroscopic and open surgery of the shoulder are associated with significant postoperative pain. Use of opioids can result in adverse systemic effects, so a multi-modal analgesic approach and complementary analgesic techniques should be considered to minimize the postoperative opioid requirement. Single shot interscalene block provides effective pain control of early and limited duration which can be extended with a catheter. Continuous interscalene block should be considered for more invasive shoulder procedures...

We designed multiple nerve transfers in one surgery to restore active pick-up function in patients with total brachial plexus avulsion injuries. Forty patients with total brachial plexus avulsion injuries first underwent multiple nerve transfers. These included transfer of the accessory nerve onto the suprascapular nerve to recover shoulder abduction, contralateral C7 nerve onto the lower trunk via the modified prespinal route with direct coaptation to restore lower trunk function and onto the musculocutaneous nerve with interpositional bridging by medial antebrachial cutaneous nerve arising from lower trunk to restore elbow flexion, and the phrenic nerve onto the posterior division of lower trunk to recover elbow and finger extension...

BACKGROUND: Rotator cuff muscle fatty degeneration after a chronic tendon tear is an irreversible pathologic change associated with poor clinical outcomes of tendon repair, and its exact pathogenesis remains unknown. We sought to investigate the role of transplanted bone marrow cells in the development of fatty degeneration, specifically in adipocyte accumulation, using a mouse model. METHODS: Fourteen mice were divided into 2 bone marrow chimeric animal groups: bone marrow transplantation (BMT) group and reverse BMT group...

BACKGROUND: Interscalene brachial plexus block is currently the gold standard for intra- and post-operative pain management for patients undergoing arthroscopic shoulder surgery. However, it is associated with block related complications, of which effect on the phrenic nerve have been of most interest. Side effects caused by general anesthesia, when this is required, are also a concern. We hypothesized that the combination of superficial cervical plexus block, suprascapular nerve block, and infraclavicular brachial plexus block would provide a good alternative to interscalene block and general anesthesia...

Interscalene brachial plexus block is considered the most complete postoperative analgesia after total shoulder arthroplasty. Interscalene brachial plexus block-induced ipsilateral hemidiaphragmatic paralysis may not be tolerated in patients with preexisting pulmonary disease. Selective distal nerve blocks avoid the risk of phrenic nerve block; however, they may provide incomplete analgesia to the glenohumeral joint. We report a case of combined selective suprascapular and axillary nerve blockade in combination with local infiltration analgesia in a patient with severe lung disease undergoing total shoulder arthroplasty...

PURPOSE: Implantation of a reverse total shoulder arthroplasty (rTSA) places the axillary and suprascapular nerves at risk. The aim of this anatomic study was to digitally analyse the location of these nerves in relation to bony landmarks in order to predict their path and thereby help to reduce the risk of neurological complications during the procedure. METHODS: A total of 22 human cadaveric shoulder specimens were used in this study. The axillary and suprascapular nerves were dissected, and radiopaque threads were sutured onto the nerves without mobilizing the nerves from their native paths...

The suprascapular nerve (SSN) can become compressed at its 2 scapular attachments: the suprascapular and the spinoglenoid notch. The objective of this study was to describe a new arthroscopic approach for SSN neurolysis at the spinoglenoid notch. Ten cadaver shoulders were used. Two were dissected to simulate the "classical" arthroscopic approach and to help in the creation of a new "direct medial retrospinal" approach. Eight other shoulders were used to validate this new approach, with control of the whole juxta-glenoid course of the SSN as criterion of success...

INTRODUCTION: This service evaluation explored and reported findings from a new physiotherapist-led service offering suprascapular nerve blocks (SSNBs) to patients with persistent shoulder pain. METHODS: We collected data before the SSNB injection and at the 6-weeks and 6-month follow-up from consecutive patients with persistent shoulder pain being treated by physiotherapists or an anaesthetist. Outcomes were patient-reported pain (numerical rating scale [NRS 0 to 10]), patient-specific functional score (PSFS) and health-related quality of life [the EuroQol five dimensions questionnaire (EQ5D-5 L)]...

Hemiplegic shoulder pain is the most common pain condition after stroke. Suprascapular nerve block is an effective treatment for shoulder pain. The aim of this pilot study was to evaluate the effects of suprascapular nerve block on pain intensity, spasticity, shoulder passive range of motion, and quality of life in long-term chronic stroke patients with hemiplegic shoulder pain. Ten chronic stroke patients (over 2 years from onset) with hemiplegic shoulder pain graded ≥30 mm on the Visual Analogue Scale underwent suprascapular nerve block injection with 1 mL of 40 mg/mL methylprednisolone and 10 mL 0...
