Editorial Commentary: Does the Scope Have a Role in Painful Shoulder Arthroplasty?

Arthroscopy 2020 06;36(6):1515-1516

Master University.

Arthroscopy is a powerful tool in the management of the painful total shoulder arthroplasty and should be considered when evaluating cases in which a clear cause of pain is not present. Patients may present with a painful shoulder arthroplasty due to a number of causes-occult infection, instability, component loosening, malposition, or rotator cuff pathology. In certain cases, advanced imaging may not be diagnostic, given the presence of metal artifact. Read More

Shoulder Conditions: Rotator Cuff Injuries and Bursitis.

FP Essent 2020 Apr;491:11-16

WellSpan York Hospital Sports Medicine Fellowship, 1001 S George St, York, PA 17403.

Subacromial impingement/pain syndrome is a common cause of shoulder pain that encompasses a spectrum of pathology of the subacromial bursa and rotator cuff tendons. Pathology of the rotator cuff tendons can range from inflammation to fibrotic changes to partial- and full-thickness tears. Biomechanical dysfunction of the rotator cuff and glenohumeral complex contributes to the pathophysiology and progression of subacromial impingement/pain syndrome. Read More

Acromioclavicular Joint: What to Look for.

Magn Reson Imaging Clin N Am 2020 May 19;28(2):269-283. Epub 2020 Feb 19.

Department of Radiology, Thomas Jefferson University Hospitals, Sidney Kimmel Medical Center, 132 South 10th Street, Suite 1096, Philadelphia, PA 19107, USA.

Acromioclavicular joint (ACJ) pathology is a common source of shoulder girdle pain, frequently coexisting with and sharing overlapping clinical features of rotator cuff and glenohumeral articular lesions. ACJ trauma and osteoarthritis dominate clinical presentation; however, an array of pathologies can affect the joint. MR imaging of the ACJ is a powerful secondary diagnostic tool in early diagnosis of ACJ pathology and in accurate assessment of ACJ injuries, helping to resolve clinically challenging cases and allowing for individualized treatment planning.

Angle of approach to the superior rotator cuff of arthroscopic instruments depends on the acromial morphology: an experimental study in 3D printed human shoulders.

J Orthop Surg Res 2019 Dec 12;14(1):435. Epub 2019 Dec 12.

Department of Orthopaedics, Balgrist University Hospital, University of Zurich, Forchstrasse 340, CH 8008, Zurich, Switzerland.

Background: Portal placement is a key factor for the success of arthroscopic procedures, particularly in rotator cuff repair. We hypothesize that the acromial anatomy may strongly determine the position of the shoulder bony landmarks and limit the surgeon's freedom to position the arthroscopic approaches in direction towards the acromion. The purpose of this study was to analyze the relation between different acromial shapes and the freedom of movement of arthroscopic instruments relative to the rotator cuff from standardized arthroscopic portals in a laboratory study on 3D shoulder models.

James F Griffith

Semin Musculoskelet Radiol 2019 Aug 11;23(4):429-435. Epub 2019 Sep 11.

The Chinese University of Hong Kong, Hong Kong.

Shoulder ultrasound is a commonly performed imaging study that can accurately determine the presence of rotator cuff tendinosis and tears, as well as subacromial-subdeltoid bursal and long head of biceps tendon pathology. High accuracy depends on an awareness of imaging pitfalls that can be encountered and lead to over- or underdiagnosis of rotator cuff pathology. Ten common pitfalls of rotator cuff ultrasound scanning are presented along with ways to avoid these pitfalls. Read More

The Influence of Different Rotator Cuff Deficiencies on Shoulder Stability Following Reverse Shoulder Arthroplasty.

Iowa Orthop J 2019 ;39(1):63-68

Department of Orthopedics and Rehabilitation, The University of Iowa, Iowa City, IA USA.

Background: The primary indication for reverse shoulder arthroplasty (RSA) is rotator cuff arthropathy caused by a deficient rotator cuff. Cuff deficiency in patients is highly variable in its distribution and extent, with mechanical implications that may significantly affect post-operative recovery. This study investigated the effects of variable cuff deficiency on the propensity for impingement between the scapula and humeral component and resulting subluxation, the source of two common complications (scapular notching and instability).

Preoperative IDEAL (Iterative Decomposition of Echoes of Asymmetrical Length) magnetic resonance imaging rotator cuff muscle fat fractions are associated with rotator cuff repair outcomes.

J Shoulder Elbow Surg 2019 Oct 29;28(10):1936-1941. Epub 2019 Jul 29.

Department of Orthopedic Surgery, Sports Medicine & Shoulder Surgery, University of California, San Francisco, San Francisco, CA, USA.

Background And Hypothesis: IDEAL (Iterative Decomposition of Echoes of Asymmetrical Length) imaging is a magnetic resonance imaging sequence that precisely measures rotator cuff muscle fatty infiltration. The influence of lower levels of fatty infiltration on outcomes after rotator cuff repair remains unclear. We hypothesized that increased preoperative fat fractions would be associated with inferior clinical outcomes after rotator cuff repair. Read More
