Editorial Commentary: Is Magnetic Resonance Imaging of the Shoulder Ever Appropriate in Evaluating Patients With Calcific Tendinopathy of the Rotator Cuff?

Arthroscopy 2020 04;36(4):991-992

Houston, Texas.

Calcific tendinopathy of the rotator cuff is a common pathology that often presents with clinical symptoms simulating a rotator cuff tear. The reported incidence of rotator cuff tear in the setting of calcific tendinopathy varies widely; however, the reported incidence of full-thickness rotator cuff tear on imaging in calcific tendinopathy is consistently low (<5%). In patients with symptomatic calcific tendinopathy, initial conservative management followed by minimally invasive treatments should be employed prior to performing shoulder magnetic resonance imaging to assess for a rotator cuff tear.

Concomitant Intra-Articular Glenohumeral Lesions in Fractures of the Scapula Body.

J Clin Med 2020 Mar 30;9(4). Epub 2020 Mar 30.

Klinikum rechts der Isar, Technische Universität München, Klinik und Poliklinik für Unfallchirurgie, Ismaninger Str. 22, 81675 München, Germany.

Background: Scapula body fractures are rare injuries with an incidence of 1% of all fractures accounting for 3% to 5% of all upper extremity fractures. Fractures of the scapula commonly result from high-energetic trauma and fall from great height. While several studies focused on concomitant injuries of chest and head as well as the cervical spine, up to now in the common literature, no study exists analyzing the prevalence of concomitant intra-articular glenohumeral injury following extra-articular scapular fracture.

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.

Contrast-Enhanced Ultrasound (CEUS) as Predictor for Early Retear and Functional Outcome After Supraspinatus Tendon Repair.

J Orthop Res 2020 May 2;38(5):1150-1158. Epub 2019 Dec 2.

Center for Orthopedics, Trauma Surgery and Spinal Cord Injury, Ultrasound Center, HTRG-Heidelberg Trauma Research Group, Heidelberg University Hospital, Schlierbacher Landstraße 200a, 69118, Heidelberg, Germany.

Supraspinatus (SSP) tendon tears represent a common indication for shoulder surgery. Yet, prediction of postoperative function and tendon retear remains challenging and primarily relies on morphologic magnetic resonance imaging (MRI)-based parameters, supported by patients' demographic data like age, gender, and comorbidities.

The Histology of a Healed Superior Capsular Reconstruction Dermal Allograft: A Case Report.

Arthroscopy 2019 10;35(10):2950-2958

TSAOG Orthopaedics and Baylor College of Medicine, San Antonio, Texas, U.S.A.

Acellular human dermal allograft commonly is used in the surgical treatment of complex rotator cuff tears, but little information is known about the biological fate of these grafts in human subjects. In this case report, the authors describe a patient who presented with a radiographically healed acellular human dermal allograft superior capsular reconstruction but had humeral head avascular necrosis. The healed superior capsular reconstruction, including graft-bone interfaces, was explanted after 7 months and sent for histologic analysis. Read More

Imaging of shoulder arthroplasties and their complications: a pictorial review.

Insights Imaging 2019 Oct 8;10(1):90. Epub 2019 Oct 8.

Radiology Department, Angers University Hospital, 4 rue Larrey, 49933, Angers, France.

Currently, an increasing number of patients benefit from shoulder prosthesis implantation. Radiologists are therefore more often confronted with imaging examinations involving shoulder arthroplasty, whether during a dedicated examination or incidentally. Standard radiography is the first-line imaging modality in the follow-up of these implants, before the possible use of cross-sectional imaging modalities (computed tomography and magnetic resonance imaging), ultrasound, or nuclear medicine examinations.

Surgical Versus Nonsurgical Management of Rotator Cuff Tears: A Matched-Pair Analysis.

J Bone Joint Surg Am 2019 Oct;101(19):1775-1782

Department of Orthopaedic Surgery, The University of Michigan, Ann Arbor, Michigan.

Background: Rotator cuff disease is a major medical and economic burden due to a growing aging population, but management of rotator cuff tears remains controversial. We hypothesized that there is no difference in outcomes between patients who undergo rotator cuff repair and matched patients treated nonoperatively.

Methods: After institutional review board approval, a prospective cohort of patients over 18 years of age who had a full-thickness rotator cuff tear seen on magnetic resonance imaging (MRI) were retrospectively evaluated. Read More
