Variability of Glenoid Labral Tear Patterns: A Study of 280 Sequential Surgical Cases.

J Shoulder Elbow Surg 2021 May 18. Epub 2021 May 18.

Peachtree Orthopaedics, Atlanta, GA, USA. Electronic address:

Background: Glenoid labrum tears are a common cause of shoulder pain and instability and tear patterns have historically been ascribed into categorical descriptions such as anterior, posterior, and superior labral tears (SLAP) with multiple sub-types. Although often quoted as representing no more than 10% of instabilities, posterior shoulder instability may be more common than previously recognized. The purpose of this study was to review observed labral tear patterns and compare incidence and morphologies to historical descriptions. Read More

Editorial Commentary: Should We Condemn the Shoulder Instability Severity Index Scoring System? Not at All!... Can We Improve Its Radiographic Component? Yes, We Can!

Arthroscopy 2021 05;37(5):1392-1396

University of Sherbrooke; Centre de Recherche du Centre Hospitalier Universitaire de Sherbrooke (CHUS), Québec, Canada.

Is patient selection necessary in shoulder instability surgery? Absolutely. The risk-benefit discussion that the surgeon must have with the patient before proposing an arthroscopic Bankart repair remains crucial to provide informed consent. The most important preoperative risk factors are incorporated in the instability severity index (ISI) score to assist surgeons in the decision-making process. Read More

Rev Med Suisse 2021 Apr;17(735):794-797

Centre orthopédique d'Ouchy, Medicol Hirslanden, Avenue d'Ouchy, 41, 1006 Lausanne.

Partial rotator cuff lesions are a common feature. The radiological assessment of choice is MRI with arthrography accompanied by ABER (abduction, external rotation) images. At present, there is no consensus on the management of these lesions and surgery remains a second-line treatment for patients who do not respond to conservative treatment. Read More

Tendon-to-bone healing after repairing full-thickness rotator cuff tear with a triple-loaded single-row method in young patients.

BMC Musculoskelet Disord 2021 Mar 26;22(1):305. Epub 2021 Mar 26.

Department of Orthopedics, Zhuhai People's hospital, Guangdong Province, Zhuhai City, China.

Background: Arthroscopic repair is recommended for young patients with full-thickness rotator cuff tears (RCTs), but the healing rates have raised concerns. The Southern California Orthopedic Institute (SCOI) row method has been developed based on greater than 3 decades of experience with excellent clinical outcomes; however, studies with a focus on the younger patient population are limited in number. The current study assessed the short-term clinical outcome and the initial tendon-to-bone healing in a young cohort after repair of a full-thickness RCT using the SCOI row method. Read More

[Reconstruction with cadaveric tricortical bone block in recurrent anterior glenohumeral dislocation with glenoid bone loss: modified Eden Hybinette technique].

Acta Ortop Mex 2020 Mar-Apr;34(2):119-122

Centro Médico ISSEMyM (Instituto de Seguridad Social del Estado de México y Municipios), Toluca, Estado de México. México.

Recurrent glenohumeral dislocation is usually associated with bone loss of the glenoid portion, with the anteroinferior location being the most affected. The understanding of the related structures, as well as the use of current imaging studies such as computed axial tomography and magnetic resonance imaging, have made progress in understanding the pathology, as well as the development of surgical materials and minimally invasive tools, they allow us to continue innovating with respect to the previously described treatments, being possible to intervene in technical details with the intention of improving the results. That is why we have done what described by Eden-Hybinette, using tricortical cadaveric graft and as fixation method, limiting the comorbidities associated with the autograft taking, resulting a wide benefit for the patient, during the surgical procedure and in the recovery period.

Cureus 2020 Oct 17;12(10):e10996. Epub 2020 Oct 17.

Orthopedic Surgery, Faculty of Medical Science, Lebanese University, Beirut, LBN.

Missed or chronic bilateral anterior shoulder dislocation is a rare presentation, usually secondary to epileptic attack. We present herein an exceptional case of this injury pattern, associated with bilateral displaced fracture of the coracoid process, and unilateral rupture of the long head of biceps. Treatment consisted of open reduction through osteotomy of the lesser tuberosity, with additional stabilization of the glenohumeral joint, using the Latarjet procedure by transposition of the coracoid fragment with its attached conjoint tendon to the antero-inferior glenoid rim.
