Choosing Wisely: the lack of validity of ultrasound scans in the investigation of shoulder instability.

N Z Med J 2022 Feb 4;135(1549):92-100. Epub 2022 Feb 4.

For assistance in data collection and preparation of this manuscript.

Aim: To test the clinical validity and financial implications of the proposed Choosing Wisely statement: "Using ultrasound as a screening test for shoulder instability is inappropriate in people under 30 years of age, unless there is clinical suspicion of a rotator cuff tear."

Method: A retrospective chart review from a specialist shoulder surgeon's practice over a two-year period recorded 124 patients under the age of 30 referred with shoulder instability. Of these, forty-one had already had ultrasound scans performed prior to specialist review. Read More

Entrapment Neuropathies of the Shoulder.

Semin Musculoskelet Radiol 2022 Apr 24;26(2):114-122. Epub 2022 May 24.

Department of Orthopedic Surgery, NYU Langone Orthopedic Hospital/NYU Langone Health, New York, New York.

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.

Management of Complex and Revision Anterior Shoulder Instability.

Arthroscopy 2022 05;38(5):1396-1397

The Steadman Clinic and Steadman Philippon Research Institute, Vail, Colorado.

Treatment of recurrent anterior shoulder instability has gained significant interest in recent years and involves evaluation of both glenoid and humeral sided bone loss. Decision making is more complex in patients with significant humeral or glenoid bone defects or in those who underwent previous instability surgery. Appropriate assessment of the glenoid track is necessary as "off track" lesions typically require treatments beyond arthroscopic labral repair alone. Read More

Two-year follow-up after operative treatment of an osseous Bankart lesion with a flap-detached cartilage lesion of the glenoid: A case report.

Acta Orthop Traumatol Turc 2022 Mar;56(2):152-156

Department of Orthopaedic Surgery, Tokyo North Medical Center, Tokyo, Japan.

Glenoid articular cartilage lesion is a rare complication following traumatic anterior dislocation of the shoulder. We report the case of a 14-year-old male rugby player with traumatic anterior shoulder instability, an extensively flapped lesion on the glenoid articular cartilage, and an osseous Bankart lesion. Arthroscopic findings revealed that the glenoid cartilage was flap-detached, extending from the anteroinferior to the center. Read More

Does native glenoid anatomy predispose to shoulder instability? An MRI analysis.

J Shoulder Elbow Surg 2022 Jun 1;31(6S):S110-S116. Epub 2022 Apr 1.

Division of Sports Medicine and Shoulder Surgery, Department of Orthopedic Surgery, Rush University Medical Center, Chicago, IL, USA. Electronic address:

Background: It is unclear if native glenohumeral anatomic features predispose young patients to instability and if such anatomic risk factors differ between males and females. The purpose of this study was to compare glenoid and humeral head dimensions between patients with a documented instability event without bone loss to matched controls and to evaluate for sex-based differences across measurements. The authors hypothesized that a smaller glenoid width and glenoid surface area would be significant risk factors for instability, whereas humeral head width would not. Read More

J Shoulder Elbow Surg 2022 Mar 22. Epub 2022 Mar 22.

Orthopedic Associates of Hartford, Farmington, CT, USA; Department of Orthopaedic Surgery, University of Connecticut, Farmington, CT, USA; Bone & Joint Institute, Hartford Hospital, Hartford, CT, USA.

Background: Partial tears of the distal biceps tendon can be difficult to diagnose based on clinical examination and magnetic resonance imaging (MRI).

Methods: Patients from a single surgeon's practice from 2000 to 2018 with a partial distal biceps tendon tear were retrospectively reviewed to determine the utility of the distal biceps palpation-rotation test in the detection of partial tears. This test is performed by palpating the bicipital tuberosity at the lateral forearm while ranging the forearm from supination to pronation with the arm adducted at the patient's side and the elbow flexed to 90°.

Imaging of traumatic shoulder injuries - Understanding the surgeon's perspective.

Eur J Radiol Open 2022 2;9:100411. Epub 2022 Mar 2.

Department of Radiology, Beth Israel Deaconess Medical Center, Harvard Medical School, 330 Brookline Ave, Boston, MA 02215, USA.

Imaging plays a key role in the assessment and management of traumatic shoulder injuries, and it is important to understand how the imaging details help guide orthopedic surgeons in determining the role for surgical treatment. Imaging is also crucial in preoperative planning, the longitudinal assessment after surgery and the identification of complications after treatment. This review discusses the mechanisms of injury, key imaging findings, therapeutic options and associated complications for the most common shoulder injuries, tailored to the orthopedic surgeon's perspective.

MR arthrography: correlation between anatomic intraarticular variants of the long head of the biceps tendon (long head biceps tendon) and superior labral anterior to posterior (SLAP) lesions.

J Orthop Traumatol 2022 Mar 8;23(1):13. Epub 2022 Mar 8.

Department of Diagnostic and Interventional Radiology, University of Insubria, Varese, Italy.

Background: The purpose of this work is to characterize the anatomy of the intraarticular portion of the long head of the biceps tendon (long head biceps tendon) using magnetic resonance (MR) arthrography by investigating whether anatomical variants may facilitate the onset of a supraequatorial lesion (superior labral anterior to posterior, SLAP).

Materials And Methods: In 482 shoulder MR arthrographies, we considered the anatomical variants of the intraarticular portion of the long head of the biceps tendon classified according to Dierickx's arthroscopic classification; lesions of supraequatorial structures were considered in the data analysis. For each anatomical variant, correlation with SLAP and the odd ratio were statistically evaluated, using Fisher's exact (or chi-squared) test and logistic regression analysis, respectively.

Editorial Commentary: Current Indications for Lateral Acromioplasty Include Patients With Elevated Critical Shoulder Angle Plus Subacromial Impingement With Rotator Cuff Pathology or Previous Rotator Cuff Repair.

Arthroscopy 2022 03;38(3):716-718

Vail, Colorado.

The critical shoulder angle (CSA) reflects the lateral extent of the acromion and the inclination of the glenoid. In 2013, CSA was first introduced and its association with rotator cuff (RC) tears and glenohumeral osteoarthritis (GHOA) was shown. It was speculated that with a high CSA, there was an increased superior force vector from the deltoid and that this superior force led to RC tears. Read More
