Multidirectional Shoulder Instability With Circumferential Labral Tear and Bony Reverse Hill Sachs: Treatment with 270° Labral Repair and Fresh Talus Osteochondral Allograft to the Humeral Head.

Arthrosc Tech 2021 Mar 15;10(3):e781-e787. Epub 2021 Feb 15.

The Steadman Clinic, Vail, Colorado, U.S.A.

Traumatic posterior dislocations of the shoulder can result in bony defects, labral tears, and cartilage injuries of the glenohumeral joint. Although traditional Hill-Sachs lesions from anterior dislocations are more commonly identified, reverse Hill-Sachs lesions caused by posterior dislocation often leads to recurrent engagement of the humeral head with the glenoid and significantly greater damage to the humeral chondral surface. In severe traumatic cases, concomitant damage of the capsulolabral soft tissues, such as circumferential labral lesions, can lead to chronic shoulder instability and residual glenoid bone loss.

Jinzhong Zhao

Arthrosc Tech 2021 Mar 2;10(3):e629-e637. Epub 2021 Feb 2.

Department of Sports Medicine, Shanghai Sixth People's Hospital, Shanghai Jiao Tong University, Shanghai, China.

The surgical results of shoulder multidirectional instability are not satisfactory. To address the structural and biological factors that are related to the low success rate of surgical treatment, we developed a whole glenoid reconstruction technique, which includes mainly 270° glenoid bone grafting and capsule labrum reconstruction, and glenohumeral ligament reconstruction. Our clinical experience indicates that the application of this technique can result in optimal shoulder stability. Read More

Glenoid Orientation and Profile in Atraumatic or Microtraumatic Posterior Shoulder Instability: Morphological Analysis Using Computed Tomography Arthrogram.

Orthop J Sports Med 2021 Feb 24;9(2):2325967120982965. Epub 2021 Feb 24.

Department of Orthopedic Surgery, Hallym University Dongtan Sacred Heart Hospital, Medical College of Hallym University, Hwaseong, Republic of Korea.

Background: Posterior shoulder instability (PSI) is a relatively uncommon condition that occurs in about 10% of patients with shoulder instability. PSI is usually associated with dislocations due to acute trauma and multidirectional instability, but it can also occur with or without recognizable recurrent microtrauma. The infrequency of atraumatic or microtraumatic PSI and the lack of a full understanding of the pathoanatomy and the knowledge of management can lead to misdiagnosis or delayed diagnosis. Read More

Anterior Capsule Augmentation and Posterior Glenohumeral Capsular Reconstruction With Human Dermal Allograft for Multidirectional Shoulder Instability.

Arthrosc Tech 2020 May 25;9(5):e657-e662. Epub 2020 Apr 25.

Division of Orthopaedic Surgery, Department of Surgery, Faculty of Medicine, Dalhousie University, Halifax, Nova Scotia, Canada.

Recurrent multidirectional shoulder instability is a common clinical presentation in certain demographics and sporting groups. One such demographic is patients with connective tissue disorders (CTD) such as Ehlers-Danlos syndrome (EDS), in whom shoulder pathologies are exacerbated owing to ligamentous laxity. Features of this laxity can present as both anterior and posterior shoulder instability, which are problematic sources of shoulder pain. Read More

Coracohumeral Ligament Reconstruction for Patients With Multidirectional Shoulder Instability.

Arthrosc Tech 2019 Jun 16;8(6):e561-e565. Epub 2019 May 16.

The Steadman Clinic, Vail, Colorado, U.S.A.

Coracohumeral ligament pathology arises from acute trauma, capsular thickening, or congenital connective tissue disorders within the glenohumeral joint. Recent studies have highlighted the significance of this pathology in multidirectional shoulder instability because insufficiency of the rotator interval has become increasingly recognized and attributed to failed shoulder stabilization procedures. The diagnosis and subsequent treatment of coracohumeral ligament pathology can be challenging, however, because patients usually present with a history of failed surgical stabilization and persistent laxity.

Age-Related Changes of Elastic Fibers in Shoulder Capsule of Patients with Glenohumeral Instability: A Pilot Study.

Biomed Res Int 2018 18;2018:8961805. Epub 2018 Jul 18.

Shoulder and Elbow Unit, "D. Cervesi" Hospital, Cattolica-AUSL della Romagna, Ambito Rimini, Italy.

Background: Recurrent shoulder dislocations occur much more frequently in adolescents than in the older population but a clear explanation of this incidence does not exist. The aim of the present study was to define the age-related distribution of the elastic fibers (EFs) in the shoulder capsule's extracellular matrix as a factor influencing shoulder instability.

Materials And Methods: Biopsy specimens were obtained from the shoulder capsule of patients divided preoperatively into three groups: Group 1 consisted of 10 male patients undergoing surgery for unidirectional traumatic anterior instability (TUBS); Group 2 consisted of 10 male patients undergoing surgery for multidirectional instability (MDI); Group 3 represents the control, including 10 patients with no history of instability.

The Thrower's Shoulder.

J Am Acad Orthop Surg 2018 Mar;26(6):204-213

From Elite Sports Medicine, Connecticut Children's Medical Center, Farmington, CT (Dr. Gelber), the Cleveland Indians Professional Baseball Organization, Cleveland, OH (Dr. Soloff), the Cleveland Clinic Sports Health Center, and the Orthopedic and Rheumatologic Institute, Cleveland (Dr. Schickendantz).

Overhead athletes subject their shoulders to extreme repetitive torque, compression, distraction, and translation stresses, resulting in adaptive changes of the soft tissues and osseous structures within and around the glenohumeral joint. These anatomic adaptations result in biomechanical enhancements, which improve performance. Understanding the difference between necessary and adaptive changes and pathologic findings is critical when making treatment decisions. Read More

Mapping glenohumeral laxity: effect of capsule tension and abduction in cadaveric shoulders.

J Shoulder Elbow Surg 2018 Apr 18;27(4):624-634. Epub 2017 Dec 18.

Sports Medicine & Shoulder Service, Hospital for Special Surgery, New York, NY, USA.

Background: Shoulder capsular plication aims to restore the passive stabilization of the glenohumeral capsule; however, high reported recurrence rates warrant concern. Improving our understanding of the clinical laxity assessment across 2 dimensions, capsular integrity and shoulder position, can help toward the standardization of clinical tools. Our objectives were to test and describe glenohumeral laxity across 5 capsular tension levels and 4 humeral position levels and describe tension-position interplay. Read More

Comparison of 2 Exercise Rehabilitation Programs for Multidirectional Instability of the Glenohumeral Joint: A Randomized Controlled Trial.

Am J Sports Med 2018 01 19;46(1):87-97. Epub 2017 Oct 19.

Department of Rehabilitation, Nutrition and Sport, School of Allied Health, College of Science, Health and Engineering, La Trobe University, Bundoora, Australia.

Background: The recommended initial treatment for multidirectional instability (MDI) of the shoulder is a rehabilitation program, yet there is very low-quality evidence to support this approach. Purpose/Hypothesis: The purpose was to compare the Watson MDI program and Rockwood Instability program among patients with nontraumatic, nonstructural MDI. The hypothesis was that the Watson MDI program would produce clinically and statistically superior outcomes over the Rockwood Instability program. Read More

Recurrent Shoulder Instability After Primary Bankart Repair.

Sports Med Arthrosc Rev 2017 Sep;25(3):123-130

*Department of Orthopaedic Surgery, Walter Reed National Military Medical Center †Uniformed Services University of Health Sciences, Bethesda, MD.

The glenohumeral joint is one of the most frequently dislocated joints and occurs with increasing frequency in collision and contact athletes, especially those in sports that repeatedly place the glenohumeral joint in a position of vulnerability. Nonoperative management of shoulder instability especially in young contact athletes results in unacceptably high recurrence rates; thus, early surgical stabilization has become commonplace. Surgical stabilization typically yields acceptable outcomes. Read More
