Variations in the Course and Diameter of the Suprascapular Nerve: Anatomical Study.

Int J Environ Res Public Health 2022 Jun 9;19(12). Epub 2022 Jun 9.

Cattedra di Radiologia "R"-DICMI, Universita di Genova, 16132 Genoa, Italy.

(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. Read More

Accuracy of suprascapular notch cross-sectional area by MRI in the diagnosis of suprascapular nerve entrapment syndrome - a retrospective pilot study.

Korean J Anesthesiol 2022 Jun 15. Epub 2022 Jun 15.

Department of Radiological Sciences, University of California, Irvine, CA, USA.

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. Read More

ADUS Klinik, Dielsdorf, Schweiz.

Pain after Shoulder Prosthesis Is Not Always Due to Infection or Loosening 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.

Suprascapular Neuropathy in Collegiate Tennis Player: A Case Report.

Cureus 2021 Dec 30;13(12):e20824. Epub 2021 Dec 30.

Physical Medicine and Rehabilitation, University of Pennsylvania, Philadelphia, USA.

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. Read More

Electrodiagnostic Assessment of Uncommon Mononeuropathies.

Neurol Clin 2021 11 3;39(4):957-981. Epub 2021 Sep 3.

Department of Neurology, Saint Louis University School of Medicine, Saint Louis, MO, USA.

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. Read More

Muscle Degeneration Induced by Sequential Release and Denervation of the Rotator Cuff Tendon in Sheep.

Orthop J Sports Med 2021 Aug 16;9(8):23259671211025302. Epub 2021 Aug 16.

University Hospital Balgrist, Department of Orthopaedics, Zurich, Switzerland.

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. Read More

Suprascapular Nerve Release: Technique Based on Anatomic Landmarks.

Arthrosc Tech 2021 Feb 15;10(2):e469-e473. Epub 2021 Jan 15.

Departamento de Anatomía, Universidad de Barcelona, Barcelona, Spain.

Dysfunction of the suprascapular nerve (SSN) is closely related to rotator cuff pathology; nerve dysfunction can lead to cuff disease and vice versa. Owing to repetitive microtrauma during overhead sports or massive cuff tears with significant tendon retraction, the SSN may suffer compression or traction neuropathy at the suprascapular notch. The SSN release technique has already been described. Read More

Editorial Commentary: Suprascapular Nerve Decompression Can Be Effective, But Should You Have the Nerve to Do It?

Arthroscopy 2021 02;37(2):508-509

University of Maryland School of Medicine.

Isolated suprascapular neuropathy that requires surgical decompression is rare. Arthroscopic suprascapular nerve decompression is an effective treatment for correctly indicated patients, but identifying which patients would benefit from decompression is challenging. While good outcomes and low complication rates after arthroscopic suprascapular nerve decompression have been reported by expert surgeons, this procedure has potential for neurovascular injury in inexperienced hands.
