From the Department of Orthopaedics, the Winn Army Community Hospital, Fort Stewart, Georgia (Dr. Cook), and the Department of Orthopaedics, the Tripler Army Medical Center, Honolulu, Hawaii (Dr. Krul).

Injuries to the acromioclavicular joint constitute approximately 3.2% of shoulder injuries. Although the overall goal of treatment continues to be return to activity with a pain-free shoulder, the treatment of acromioclavicular joint separations has been fraught with conflict since the earliest reports in both ancient and modern literature.

[Effectiveness of anatomical locking plate internal fixation combined with coracoclavicular ligament reconstruction for Neer type b distal clavicle fractures].

Zhongguo Xiu Fu Chong Jian Wai Ke Za Zhi 2018 09;32(9):1181-1186

Department of Orthopaedics, Jiading Center Hospital, Shanghai, 201800,

Objective: To investigate the effectiveness of anatomical locking plate internal fixation combined with coracoclavicular ligament reconstruction in treatment of the Neer type Ⅱb distal clavicle fractures by comparing with the simple anatomical locking plate internal fixation.

Methods: The clinical data of 40 patients with Neer type Ⅱb distal clavicle fractures who met the criteria between February 2013 and January 2017 were analyzed. Eighteen cases were treated with anatomical locking plate internal fixation and coracoclavicular ligament reconstruction by using a suture anchor (reconstruction group), and 22 cases were treated only with anatomical locking plate internal fixation (non-reconstruction group).

Acromio-Clavicular Joint Dislocation Types IV to VI: Does the Outcome with the modified Weaver-Dunn Procedure Justify the Treatment?

Malays Orthop J 2018 Jul;12(2):31-36

Department of Orthopaedics, Civil Service Hospital, Kathmandu, Nepal.

The optimal surgical treatment for acromioclavicular joint (ACJ) injuries remains controversial. The modified Weaver-Dunn (WD) procedure is one of the frequently used techniques. Recently when it was compared with anatomical autogenous tendon graft reconstruction procedures, the results were inferior. Read More

Stabilization of Acute High-Grade Acromioclavicular Joint Separation: A Prospective Assessment of the Clavicular Hook Plate Versus the Double Double-Button Suture Procedure.

Am J Sports Med 2018 Sep 14;46(11):2725-2734. Epub 2018 Aug 14.

Department of Trauma and Orthopedic Surgery, Berufsgenossenschaftliche Unfallklinik Frankfurt am Main, Frankfurt am Main, Germany.

Background: The stabilization strategy for acute high-grade acromioclavicular (AC) joint separations with AC-stabilizing clavicular hook plate (cHP) or coracoclavicular (CC)-stabilizing double double-button suture (dDBS) is still under consideration.

Hypothesis: The CC-stabilizing dDBS is superior to the cHP according to an AC-specific radiologic assessment and score system.

Study Design: Cohort study; Level of evidence, 2. Read More

Low prevalence of relevant associated articular lesions in patients with acute III-VI acromioclavicular joint injuries.

Knee Surg Sports Traumatol Arthrosc 2018 Aug 10. Epub 2018 Aug 10.

Hospital Asepeyo Coslada, Madrid, Spain.

Purpose: To define the prevalence of associated articular injuries in patients with severe (Rockwood's III-VI) acute acromioclavicular joint injuries and to find out how many of these were associated with the traumatic event and required surgical treatment.

Methods: Retrospective observational multicentric study performed in ten centres included patients who required surgery for acute acromioclavicular joint injuries between 2010 and 2017. The inclusion criteria were: presence of an acute acromioclavicular joint injury (grades III-IV-V-VI) and surgical treatment within 3 weeks of injury that included a full arthroscopic evaluation of the shoulder.
