Suprascapular neuropathy

(1) Background: Suprascapular neuropathy is an important factor contributing to shoulder pain. Given the prevalence of nerve injury and nerve block in the suprascapular notch region, as well as the frequency of arthroscopic procedures on the suprascapular notch, which are recommended in shoulder pain management, its morphology is relevant from a clinical perspective. (2) Methods: Suprascapular nerve course was studied in twelve shoulders by dissection. Its diameter was measured at omohyoid level, proximal to the suprascapular notch and distal to the spinoglenoid notch...

Background: Suprascapular nerve entrapment syndrome (SNES) is a peripheral neuropathy caused by compression of the suprascapular nerve. Previous studies have demonstrated that the suprascapular notch`s morphological change is closely correlated with SNES. Thus, we thought that the suprascapular notch cross-sectional area (SSNCSA) might be a good diagnostic parameter to assess SNES. Methods: We acquired suprascapular notch data from 10 patients with SNES and from 10 normal individuals who had taken shoulder magnetic resonance imaging (S-MRI) and no evidence of SNES...

Entrapment neuropathies of the shoulder most commonly involve the suprascapular or axillary nerves, and they primarily affect the younger, athletic patient population. The extremes of shoulder mobility required for competitive overhead athletes, particularly in the position of abduction and external rotation, place this cohort at particular risk. Anatomically, the suprascapular nerve is most prone to entrapment at the level of the suprascapular or spinoglenoid notch; the axillary nerve is most prone to entrapment as it traverses the confines of the quadrilateral space...

Pain after Shoulder Prosthesis Is Not Always Due to Infection or Loosening Abstract. Summary: Suprascapular nerve neuropathy is becoming increasingly recognized as a reason for persistent shoulder pain. The underlying cause may be iatrogenic, as in the case of our patient, or due to ganglionic compression or traction. Unfortunately, diagnosis and thus adequate therapy is frequently delayed. With this case study, we would like to bring the neuropathy of the suprascapular nerve into focus for the general practice...

Suprascapular neuropathy can be seen in overhead athletes and should be considered when evaluating an overhead athlete presenting with shoulder pain and/or weakness. The suprascapular nerve innervates the supraspinatus and the infraspinatus, but dynamic entrapment as it passes under the spinoglenoid ligament at the spinoglenoid notch can lead to isolated denervation of the infraspinatus. Specific movements common in tennis cause tensioning and compression of the spinoglenoid ligament and may predispose players to dynamic entrapment at this location...

Nerve ultrasound has become an integral part of the diagnostic workup of peripheral neuropathies. Especially in the examination of small nerves, ultrasound provides superior image quality by using high frequency transducers. For a selection of small nerves, this article summarizes the local anatomy and common pathologies and offers simple instructions for determining their location with ultrasound including some cases with pathologies. This selection of nerves comprises the great auricular nerve, the supraclavicular nerves, the suprascapular nerve, the medial antebrachial cutaneous nerve, the lateral antebrachial cutaneous nerve, the palmar cutaneous branch of the median nerve, the long thoracic nerve, the intercostobrachial nerve, the posterior cutaneous nerve, the infrapatellar branch of the saphenous nerve, the medial calcaneal nerve, and the deep peroneal nerve at the ankle...

BACKGROUND: Baseplate screws have been suggested to be a possible cause of suprascapular neuropathy after reverse total shoulder arthroplasty (RTSA). Three-dimensional analyses of screw penetration and confirmation of its clinical impacts are relevant. The study aims to investigate the association between screw penetration and the clinical outcomes. MATERIALS AND METHODS: Eighty-two patients who underwent RTSA for a massive rotator cuff tear, cuff tear arthropathy, or osteoarthritis with rotator cuff tear were retrospectively enrolled...

Suprascapular nerve entrapment syndrome (SNES) is an often-overlooked etiology of shoulder pain and weakness. Treatment varies depending on the location and etiology of entrapment, which can be described as compressive or traction lesions. In some cases, treating the primary cause of impingement (ie. rotator cuff tear, ganglion cyst, etc.) is sufficient to relieve pressure on the nerve. In other cases where impingement is caused by dynamic microtrauma (as seen in overhead athletes and laborers), treatment is often more conservative...

PURPOSE OF THE STUDY To compare the functional and radiological results of the total arthroscopic treatment (TAT) performed due to the rotator cuff (RC) tear problem with the results of the arthroscopically assisted mini-open surgery (AAMOS). MATERIAL AND METHODS This study conducted over a two-year period included all had TAT or AAMOS. Patients were included in the study if they had undergone arthroscopic or mini-open rotator cuff repair, with a minimum of 2 years' follow-up. Patients were divided into two groups in terms of the surgical technique performed...

Carpal tunnel syndrome, ulnar neuropathy at the elbow, and peroneal neuropathy are the most common mononeuropathies; however, other individual nerves may also be injured by various processes. These uncommon mononeuropathies may be less readily diagnosed owing to unfamiliarity with the presentations and vague symptoms. Electrodiagnostic studies are essential in the evaluation of uncommon mononeuropathies and can assist in localization and prognostication. However, they can also be challenging; stimulation at the proximal sites is difficult and well-validated reference values are not available...

BACKGROUND: Pain management is crucial in palliative care for patients with advanced cancer. Here, we report a case of shoulder pain in a patient with renal cell carcinoma. CASE PRESENTATION: A 36-year-old male diagnosed metastatic renal cell carcinoma presented with pain and weakness on left shoulder for more than 6 months. Physical examination showed limited range of motion and atrophic changes on supraspinatus and infraspinatus muscles. Weakness in shoulder abduction and external rotation was also noted...

BACKGROUND: In a sheep rotator cuff model, tenotomy predominantly induces fatty infiltration, and denervation induces mostly muscle atrophy. In clinical practice, myotendinous retraction after tendon tear or lateralization after tendon repair tear may lead to traction injury of the nerve. PURPOSE/HYPOTHESIS: To analyze whether an additional nerve lesion during rotator cuff repair leads to further degeneration of the rotator cuff muscle in the clinical setting. We hypothesized that neurectomy after tendon tear would increase atrophy as well as fatty infiltration and that muscle paralysis after neurectomy would prevent myotendinous retraction after secondary tendon release...

Background  The suprascapular notch (SN) represents the point along the route of the suprascapular nerve (SSN) with the greatest potential risk for injury and compression. Thus, factors reducing the area of the notch have been postulated for suprascapular neuropathy development. Methods  Thirty-one fresh-frozen shoulders were dissected. The contents of the SN were described according to four types as classified by Polguj et al and the middle-transverse diameter of the notch was measured. Also, the presence of an ossified superior transverse scapular ligament (STSL) was identified...

BACKGROUND: Suprascapular neuropathy has been observed in the setting of rotator cuff tears (RCTs), but its association with these tears and their treatment are unclear. HYPOTHESIS: Arthroscopic suprascapular nerve release during rotator cuff repair will not alter the outcomes of neuropathy. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: A total of 42 patients with large/massive reparable RCTs and suprascapular neuropathy were recruited and followed up at 6 and 12 months...

INTRODUCTION: Only a few previous studies have evaluated the factors related to supraclavicular nerve (SCN) injury after clavicle mid-shaft fracture surgery. We analyzed the frequency and risk factors for SCN injury after clavicle mid-shaft fracture surgery via open reduction and internal fixation (ORIF) versus minimally invasive plate osteosynthesis (MIPO) MATERIALS AND METHODS: We retrospectively reviewed the cases from 59 patients who had undergone surgery for clavicle mid-shaft fractures between January 2018 and April 2019...

OBJECTIVE: To evaluate ferumoxytol-enhanced vascular suppression for visualizing branch nerves of the brachial plexus in magnetic resonance (MR) neurography. MATERIALS AND METHODS: Signal simulations were performed to determine ferumoxytol's effect on nerve-, fat-, and blood-to-muscle contrast and to optimize pulse sequence parameters. Prospective, in vivo assessment included 10 subjects with chronic anemia who underwent a total of 19 (9 bilateral) pre- and post-infusion brachial plexus exams using three-dimensional (3D), T2 -weighted short-tau inversion recovery (T2 -STIR) sequences at 3...

CASE: A 46-year-old man underwent open reduction and internal fixation (ORIF) of left scapular, humerus, and clavicle fractures after a snowmobile accident. He subsequently developed severe left infraspinatus weakness with electromyogram evidence of suprascapular entrapment at the spinoglenoid notch. Intraoperatively, suprascapular nerve compression from an ossified spinoglenoid ligament was observed. Scapular hardware was removed, the ossified ligament was resected, and neurolysis was performed...
