An intact subscapularis tendon and compensatory teres minor hypertrophy yield lower failure rates for non-operative treatment of irreparable, massive rotator cuff tears.

Knee Surg Sports Traumatol Arthrosc 2019 Feb 15. Epub 2019 Feb 15.

Department of Orthopaedic Surgery, Severance Hospital, Arthroscopy and Joint Research Institute, Yonsei University College of Medicine, 50-1 Yonsei-ro, Seodaemun-gu, CPO Box 8044, Seoul, 03722, Republic of Korea.

Purpose: To investigate whether subscapularis integrity and compensatory teres, minor hypertrophy is associated with maintaining relatively good function and tolerable pain levels during non-operative treatment.

Methods: This study included 108 patients with irreparable, massive rotator cuff tears involving at least two tendons and stage III or IV muscle hypotrophy and fatty infiltration on oblique sagittal magnetic resonance imaging, in which even a partial repair does not seem feasible. All supraspinatus and infraspinatus muscles were grade IV; if the subscapularis was involved, only stage III or IV was included. Read More

Pigmented villonodular synovitis.

Folia Med Cracov 2018 ;58(4):93-104

Human Anatomy Department, Medical University of Lublin; Radiology Department, St Johns' Cancer Center; Lublin, Poland.

Pigmented villonodular synovitis (PVNS) is a benign disease that rarely undergoes malignant transformation. There are two types of disease: localized (nodular tenosynovitis) and di used (pigmented villonodular synovitis/tenosynovitis) with intra- or extra-articular locations. The second one is limited to synovium of the burse (PVNB) or tendon sheath (PVNTS). Read More

Ulnar Collateral Ligament Insertional Injuries in Pediatric Overhead Athletes: Are MRI Findings Predictive of Symptoms or Need for Surgery?

AJR Am J Roentgenol 2019 Jan 30:1-7. Epub 2019 Jan 30.

1 Department of Radiology, New York-Presbyterian Hospital-Columbia University Medical Center, 622 W 168th St, MC-28, New York, NY 10032.

Objective: The purpose of this study was to determine whether ulnar collateral ligament (UCL) insertion below the articular margin (so-called T sign) exists in the pediatric population and whether MRI features can be used to identify insertional UCL injuries in overhead athletes that are symptomatic or require surgery.

Materials And Methods: Retrospective review of elbow MR images of patients younger than 21 years from 2011 to 2017 yielded 26 control subjects who were not overhead athletes and 97 overhead athletes. According to the clinical diagnosis, 50 of the overhead athletes had symptoms. Read More

Efficacy of suprascapular nerve block compared with subacromial injection: a randomized controlled trial in patients with rotator cuff tears.

J Shoulder Elbow Surg 2019 Jan 14. Epub 2019 Jan 14.

Townsville Hospital, Douglas, QLD, Australia; Greenslopes Private Hospital, Brisbane, QLD, Australia.

Hypothesis: We aimed to compare the clinical efficacy of a suprascapular nerve block (SSNB) versus subacromial injection (SA) for outpatient treatment of patients with symptomatic rotator cuff tears in a double-blinded, randomized controlled trial using sealed-envelope randomization.

Methods: A total of 42 participants with symptomatic partial- and full-thickness rotator cuff tears quantified by ultrasound or magnetic resonance imaging received either an ultrasound-guided SSNB or SA. The primary outcome measure was shoulder function measured by the modified Constant-Murley (CM) score and the secondary outcome was the pain score measured by a visual analog scale at 2, 6, and 12 weeks after injection.

Georgetown University School of Medicine, MedStar National Rehabilitation Network, Washington, DC.

Platelet-rich plasma (PRP), as a regenerative treatment for partial ulnar collateral ligament (UCL) tears, is validated to lead to faster clinical recovery and return to play in adult athletes. However, studies examining such a role of PRP in younger pediatric and adolescent athletes are scarce. A 14-year-old adolescent throwing athlete, a right-handed pitcher, presented with chronic right medial elbow pain discovered to be secondary to a partial UCL tear, as identified on both ultrasound and magnetic resonance imaging.

Department of Orthopaedic Surgery, Severance Hospital, Arthroscopy and Joint Research Institute, Yonsei University College of Medicine, 50-1 Yonsei-ro, Seodaemun-gu, CPO Box 8044, Seoul, 120-752, South Korea.

Purpose: The purpose of this study was to investigate the natural history of intact rotator cuff in impingement syndrome patients with concomitant spur protruding from the undersurface of acromion.

Methods: This retrospective study included 119 patients with an intact rotator cuff who underwent conservative treatment for a spur protruding from the undersurface of the acromion. The protruded spur was defined as a trapezoid- or tetragon-shaped bony protrusion with a downward peak extending more than 3 mm in length from the baseline drawn along the acromial undersurface on the coronal view of magnetic resonance imaging (MRI) or computed tomography arthrography (CTA).

A Comparative Study to Evaluate the Risk Factors for Medium-Sized Rotator Cuff Tear in Patients Younger Than 50 Years of Age.

Arthroscopy 2018 Nov;34(11):2971-2979

Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea. Electronic address:

Purpose: The purpose of this study was to evaluate preoperative and intraoperative factors associated with rotator cuff tears (RCTs) among patients younger than 50 years and to compare arthroscopic rotator cuff repair (RCR) results in patients younger than 50 years (group A) and patients older than 70 years (group B). We also analyzed the results after arthroscopic RCR in these 2 age groups.

Methods: Data were collected from 56 patients allocated to group A and 55 patients allocated to group B who had medium-sized RCTs and had undergone arthroscopic RCR between January 2006 and August 2015. Read More

Superior Capsular Reconstruction Reverses Profound Pseudoparalysis in Patients With Irreparable Rotator Cuff Tears and Minimal or No Glenohumeral Arthritis.

Arthroscopy 2019 Jan 30;35(1):22-28. Epub 2018 Oct 30.

San Antonio Orthopaedic Group and Burkhart Research Institute for Orthopaedics, San Antonio, Texas, U.S.A.. Electronic address:

Purpose: The purpose of the study was to investigate the rate and magnitude of return of active forward elevation (aFE) of the arm for patients with severe preoperative elevation dysfunction (less than 45° of aFE and termed profound pseudoparalysis) and massive, irreparable (or partially reparable) rotator cuff tears without arthritis treated with arthroscopic superior capsular reconstruction (SCR).

A Pediatric Medial Epicondyle Fracture Cadaveric Study Comparing Standard AP Radiographic View With the Distal Humerus Axial View.

J Pediatr Orthop 2019 Mar;39(3):e205-e209

Children's Hospital Colorado, Aurora, CO.

Background: Controversy exists with regard to the amount of fracture displacement that warrants surgical fixation of medial epicondyle fractures. Inaccurate determination of degree of displacement on plain radiographs may account for the disputed management. Recently, a novel distal humerus axial radiograph technique has been developed to improve the accuracy of radiographs. Read More

Acromioclavicular joint cyst formation in a patient with rotator cuff-tear arthropathy: a rare cause of shoulder discomfort.

BMJ Case Rep 2018 Sep 27;2018. Epub 2018 Sep 27.

Department for Shoulder and Elbow Surgery, Charite Universitatsmedizin Berlin Campus Virchow-Klinikum, Berlin, Germany.

We report a case of a 77-year-old man who presented to our shoulder department with a soft tissue mass on his right acromioclavicular (AC) joint. Previously attempted puncture aspiration had revealed serous fluid retention which recurred after each of several drainage attempts. Conventional radiography and MRI of the affected shoulder joint demonstrated a progressed cuff-tear arthropathy with an irreparable tear of the supraspinatus tendon, static superior migration of the humeral head, opening of the AC joint capsule and a superior joint-fluid 'eruption' and accumulation called 'Geyser sign'.
