Acromioclavicular Joint Disk Tearing in Young Non-Arthritic Individuals: A Case Series.

J Orthop Case Rep 2020 May-Jun;10(3):90-94

Department of Orthopaedic Surgery, University of Michigan Medical School, MedSport Domino's Farms, 24 Frank Lloyd Wright Drive, Lobby A, Suite 1000, Ann Arbor, MI 48106 USA.

Introduction: Degeneration of the fibrocartilaginous acromioclavicular (AC) joint disk can become significant in later life and lead to primary osteoarthritis and shoulder pain. Younger, non-arthritic individuals may develop residual shoulder symptoms due to tearing of the disk itself.

Editorial Commentary: Suture Button-Anchor Fixation Is Preferable to Hook Plate Fixation for Acute Acromioclavicular Joint Dislocations: Form and Function Need to Be United.

Arthroscopy 2021 05;37(5):1424-1426

Both hook plate fixation and suture button-anchor fixation have been reported to yield good results in the treatment of acute acromioclavicular joint reconstruction. In addition to a mandatory secondary procedure, hook plate fixation clearly has an increased prevalence of post-traumatic acromioclavicular arthritis in the short term that is likely to progress in the long term. Conversely, suture button-anchor fixation-a minimally invasive technique that creates less soft-tissue disruption, does not require hardware removal, and does not violate the acromioclavicular joint-is more likely to promote primary healing of the coracoclavicular ligaments, reduce the risk of late displacement, and minimize the development of post-traumatic acromioclavicular arthritis.

Editorial Commentary: Acute Repair of the Acromioclavicular Joint Capsule and Ligaments and Deltotrapezial Fascia Could Allow Biological Healing of High-Grade Acromioclavicular Separation-Coracoclavicular Ligament Graft Augmentation Could Be Indicated if Time to Surgery Is Greater Than 3 Weeks.

Arthroscopy 2021 04;37(4):1096-1098

Humanitas University.

Surgical management of chronic acromioclavicular joint (ACJ) dislocations is a matter of controversy. In the acute setting of high-grade acromioclavicular separation, if a surgical repair of the ACJ capsule and ligaments and deltotrapezial fascia could allow biological healing of the ligaments themselves, this could be enough to restore the functional biomechanics of the joint; unfortunately, this is not true for chronic cases. In the latter situation, a surgical technique using biological augmentation such as autograft or allograft should be preferred. Read More

To explore the reasonable selection of clavicular hook plate to reduce the occurrence of subacromial impingement syndrome after operation.

J Orthop Surg Res 2021 Mar 9;16(1):180. Epub 2021 Mar 9.

Department of Orthopaedic Trauma, Hong Hui Hospital, Xi'an Jiaotong University School of Medicine, Xi'an, 710054, Shaanxi, China.

Background: Acromioclavicular joint dislocation is a shoulder joint injury common in the clinical setting and is generally surgically treated with clavicular hook plate technique with confirmed curative effect. However, symptoms such as shoulder abduction limitation, shoulder discomfort and joint pain postoperatively may occur in some patients. Therefore, this study aimed to explore whether the existing clavicular hook plate can be reasonably selected to reduce the incidence of subacromial impingement syndrome (SIS) and provide a reference for clinical diagnosis and treatment.

Mini open triple tunnel- double flip button techniques in treatment of acute acromioclavicular joint injuries: Case report.

Trauma Case Rep 2021 Apr 26;32:100450. Epub 2021 Feb 26.

Department of Orthopedics, Faculty of Medicine, Universitas Indonesia, Cipto Mangunkusumo Hospital, Jakarta, Indonesia.

Acute acromioclavicular (AC) joint injuries are common and often occur in a contact sport activity. Most acute AC joint injuries surgery techniques focus on coracoclavicular (CC) ligament complex fixation; by single or double clavicle tunnel, but persisting vertical instability. In this paper, we introduce mini open triple tunnel- double flip button (TTDB) technique for acute AC joint dislocation by adding tunnel on clavicle to expand coverage of footprint of conoid and trapezoid ligament in order to improve vertical stability of the AC joint.

Is coracoclavicular reconstruction necessary in hook plate fixation for acute unstable acromioclavicular dislocation?

BMC Musculoskelet Disord 2021 Feb 1;22(1):127. Epub 2021 Feb 1.

Department of Orthopedic Surgery, Kaohsiung Chang Gung Memorial Hospital, 123 Ta Pei Road, Niao Sung Dist, Kaohsiung, Taiwan.

Background: Acromioclavicular joint (ACJ) dislocation is a relatively common shoulder injury. For the treatment of cases of severe ACJ dislocation (Rockwood type III-V), hook plate fixation is an easy-to-master and minimally-invasive approach to surgical intervention. Over stress on the acromion following hook plate fixation often leads to acromial complications such as osteolysis and loss of reduction. Read More

Department of Orthopedic Surgery, Arthroscopy and Joint Research Institute, Severance Hospital, Yonsei University College of Medicine, Seoul, Korea.

Acromioclavicular (AC) joint dislocations account for about 9% of shoulder injuries. Among them, acute high-grade injury following high-energy trauma accounts for a large proportion of patients requiring surgical treatment. However, there is no gold standard procedure for operative treatment of acute high-grade AC joint injury, and several different procedures have been used for this purpose in clinical practice.
