Influence of a nerve injury proximal to the suprascapular nerve on healing of repaired rotator cuff tear.

J Orthop Sci 2019 Mar 8. Epub 2019 Mar 8.

Department of Orthopaedic Surgery, Chiba University After Graduate School of Medicine, Japan.

Background: Massive rotator cuff tears have a high rate of re-injury because of severe fatty infiltration. Our data showed that injuries proximal to the suprascapular nerve may be one cause of massive rotator cuff tears. The purpose of this study was to evaluate, using a rat model, how brachial plexus injury associated with a massive rotator cuff tear influences healing of the rotator cuff repair. Read More

Hourglass-like constriction neuropathy of the suprascapular nerve detected by high-resolution magnetic resonance neurography: report of three patients.

Skeletal Radiol 2019 Feb 12. Epub 2019 Feb 12.

Department of Physical and Rehabilitation Medicine, Samsung Medical Center, Sungkyunkwan University School of Medicine, 81 Irwon-Ro, Gangnam-gu, Seoul, 06351, South Korea.

Hourglass-like constriction neuropathy is a neurological condition caused by non-traumatic, non-compressive fascicular constrictions of one or more individual peripheral nerves. Based on clinical manifestations, it is very difficult to differentiate hourglass-like constriction neuropathy from idiopathic neuralgic amyotrophy. Focal hourglass-like constriction neuropathy may be erroneously diagnosed as idiopathic neuralgic amyotrophy. Read More

Basis of Shoulder Nerve Entrapment Syndrome: An Ultrasonographic Study Exploring Factors Influencing Cross-Sectional Area of the Suprascapular Nerve.

Front Neurol 2018 23;9:902. Epub 2018 Oct 23.

Department of Physical and Rehabilitation Medicine, Hacettepe University Medical School, Ankara, Turkey.

As changes in nerves' shape and size are common ultrasonographic findings of entrapment neuropathy, measurement of the nerve cross-sectional area (CSA) becomes the mostly used indicator to differentiate normality from pathology. Recently, more US research has been conducted to measure the shape of the suprascapular notch and the diameter of the suprascapular nerve. Because the suprascapular nerve is paramount for various shoulder disorders, the present study aims to establish normal values of suprascapular nerve sizes at different levels as well as to investigate potential influence of participants' characteristics on the CSA measurements.

Editorial Commentary: Suprascapular Neuropathy in Overhead Athletes: To Release or Not to Release?

Authors:
Patrick J Denard

Arthroscopy 2018 Sep;34(9):2558-2559

A growing body of evidence has demonstrated that repetitive overhead athletes with shoulder pathology often have associated infraspinatus atrophy and suprascapular neuropathy. Although decompression of the suprascapular nerve has not been shown to clearly impact outcomes in the general population, release of the nerve in overhead athletes with documented evidence of impingement may improve outcomes in this high-demand population.

A Large Size Lipoma at Spinoglenoid Notch Mimicked Traumatic Rotator Cuff Tear.

J Hand Surg Asian Pac Vol 2018 Jun;23(2):267-269

* Department of Orthopedic Surgery, Myongji Hospital, Goyang, Korea.

Herein, we report a large lipoma at the spinoglenoid notch that mimicked a rotator cuff tear, which occurred in a 61-year-old male farmer. Weakness and pain in the shoulder started abruptly after hard labor, and our first impression was a traumatic rotator cuff tear; however, there was no tear on MRI, and complete marginal excision of a large lipoma at the spinoglenoid notch relieved the symptoms completely at a postoperative three-month follow-up visit. We believe that certain activities such as forceful shoulder abduction may have caused the sudden onset of suprascapular neuropathy in the loosely compressed suprascapular nerve by the lipoma.

A new anatomical insight into the aetiology of lateral trunk of suprascapular nerve neuropathy: isolated infraspinatus atrophy.

Surg Radiol Anat 2018 Mar 9;40(3):333-341. Epub 2018 Mar 9.

Department of Angiology, Interfaculty Chair of Anatomy and Histology, Medical University of Łódź, Narutowicza 60, 90-136, Lodz, Poland.

Introduction: Although the pathomechanism of isolated infraspinatus atrophy (ISA) in throwing sports is known to be traction, it is unclear why only some players are affected. One likely explanation is that the infraspinatus pulling force exerted by its contracture generate the compressive resultant component force (Fn) compressing the lateral trunk of the suprascapular nerve (LTSN) against the edge of scapular spine. This paper makes two key assumptions (1) the course of LTSN in relation to the scapular spine, defined as the suprascapular-scapular spine angle (SSSA) is the key individual anatomical feature influencing the Fn magnitude, and thus potentially ISA development (2) SSSA is correlated with scapular notch type.

Relationship between neuropathy proximal to the suprascapular nerve and rotator cuff tear in a rodent model.

J Orthop Sci 2018 Mar 12;23(2):414-419. Epub 2018 Jan 12.

Department of Orthopedic Surgery, Graduate School of Medicine, Chiba University, Japan.

Background: Rotator cuff tears are believed to coexist with cervical spine lesions. In cases of preexisting neuropathy, such as cervical spine lesions, fatty degeneration has likely already occurred due to the neuropathy. In these cases, rotator cuff tear is thought to occur easily because of preexisting extensive fatty degeneration and degeneration of the tendons due to neuropathy. Read More

Suprascapular neuropathy in the setting of rotator cuff tears: study protocol for a double-blinded randomized controlled trial.

Trials 2016 11 22;17(1):554. Epub 2016 Nov 22.

First Orthopaedic Department, Aristotle University of Thessaloniki, Thessaloniki, Greece.

Background: It has been indicated that rotator cuff tears, especially large or massive ones, can cause suprascapular neuropathy. When such a diagnosis has been established, it is still unknown whether an arthroscopic release of the superior transverse scapular ligament during cuff repair can change the course of this neuropathy.

Methods/design: This is a single-center, double-blinded randomized controlled trial for which 42 patients with large or massive repairable rotator cuff tears and suprascapular neuropathy will be recruited and followed up at 6 and 12 months. Read More

A quantitative study of the arrangement of the suprascapular nerve and vessels in the suprascapular notch region: new findings based on parametric analysis.

Folia Morphol (Warsz) 2016;75(4):454-459. Epub 2016 Nov 10.

Department of Angiology, Interfaculty Chair of Anatomy and Histology, Medical University of Łódź, Poland.

Background: When closed by the superior transverse scapular ligament (STSL), the suprascapular notch (SSN) creates an osseo-fibrous tunnel which acts as a pathway for the suprascapular nerve (SN). Anatomical variations are common in this region, and these can increase the risk of neuropathy by restricting the space for nerve passage. The aim of this study is to identify any correlation between the area reduction coefficient parameters and the SN and vessel arrangements in the SSN region. Read More

[SUPRASCAPULAR NEUROPATHY].

Rev Med Liege 2016 May;71(5):242-7

Supra-scapular nerve (SSN) damage is a rare, but classical diagnosis that can often be overlooked since the nonspecific clinical history and examination commonly lead to the misdiagnosis of another shoulder disorder. This article details the etiopathology, the patients at risk, the reasons for consultation and the clinical aspects of suprascapular neuropathy; it also outlines its diagnostic and therapeutic approaches.

Suprascapular nerve injury: A cause to consider in shoulder pain and dysfunction.

J Back Musculoskelet Rehabil 2016 May 13. Epub 2016 May 13.

Department of Orthopaedic Surgery, Monash Health, Clayton VIC, Australia.

Suprascapular nerve injury is increasingly being recognized as an important cause of shoulder dysfunction. The non-specific clinical features of suprascapular nerve injury can make diagnosis difficult. However, it is essential for clinicians to consider it as part of the differential diagnoses in patients with vague pain or sensory disturbances over the posterosuperior part of their shoulder or have unexplained atrophy and weakness of their supraspinatus or infraspinatus muscle.

Type 2 Superior Labral Anterior to Posterior Lesion-Related Paralabral Cyst Causing Isolated Infraspinatus Paralysis: Two Case Reports.

Ann Rehabil Med 2015 Oct 26;39(5):848-52. Epub 2015 Oct 26.

Department of Rehabilitation Medicine, Jeju National University Hospital, Jeju National University School of Medicine, Jeju, Korea.

Type 2 superior labral anterior to posterior (SLAP) lesion is a common cause of shoulder pain requiring surgical operation. SLAP tears are often associated with paralabral cysts, but they rarely cause nerve compression. However, we experienced two cases of type 2 SLAP-related paralabral cysts at the spinoglenoid notch which were confirmed as isolated nerve entrapment of the infraspinatus branch of the suprascapular nerve by electrodiagnostic assessment and magnetic resonance imaging.

Department of Radiology, University of California San Diego, La Jolla, CA, USA; Department of Orthopaedic Surgery, University of California San Diego, La Jolla, CA, USA; Department of Bioengineering, University of California San Diego, La Jolla, CA, USA. Electronic address:

Rotator cuff (RC) disease is an extremely common condition associated with shoulder pain, reduced functional capacities, and impaired quality of life. It primarily involves alterations in tendon health and mechanical properties that can ultimately lead to tendon failure. RC tendon tears induce progressive muscle changes that have a negative impact on surgical reparability of the RC tendons and clinical outcomes. Read More

What is the function of the anterior coracoscapular ligament? - a morphological study on the newest potential risk factor for suprascapular nerve entrapment.

Ann Anat 2015 Sep 6;201:38-42. Epub 2015 Jul 6.

Department of Angiology, Interfaculty Chair of Anatomy and Histology, Medical University of Łódź, Poland.

Background: The suprascapular notch (SSN) is the most common site of suprascapular nerve neuropathy, which may be brought on by the presence of a deep, narrow SSN and structures restricting the space for the nerve. The anterior coracoscapular ligament (ACSL) is a fibrous band extending on the anterior side of the suprascapular notch. As it may tighten the osteo-fibrous tunnel for the nerve, it has been proposed as a new anatomical risk factor in its entrapment. Read More
