The Morphology of the Acromioclavicular Joint Does Not Influence the Postoperative Outcome Following Acute Stabilization-A Case Series of 81 Patients.

Arthrosc Sports Med Rehabil 2022 Jun 15;4(3):e835-e842. Epub 2022 Apr 15.

Department of Orthopedic Sports Medicine, Technical University of Munich, Klinikum rechts der Isar, Munich, Germany.

Purpose: To specifically evaluate the influence of the acromioclavicular (AC)-joint morphology on the outcome after arthroscopically assisted coracoclavicular (CC) stabilization surgery with suspensory fixation systems and to investigate whether an additional open AC-joint reduction and AC cerclage improves the clinical outcome for patients with certain morphologic AC-joint subtypes.

Methods: Patients with an acute acromioclavicular joint injury, who underwent arthroscopically assisted CC stabilization with suspensory fixation systems with or without concomitant AC cerclage between January 2009 and June 2017 were identified and included in this retrospective cohort analysis. AC-joint morphology was assessed on preoperative radiographs and categorized as "flat" or "non-flat" ("oblique"/"curved") subtypes. Read More

Arthroscopically Assisted Acromioclavicular and Coracoclavicular Reconstruction with a Looped Braided Polyester Suture Band and Buckle Device.

Arthrosc Tech 2022 May 22;11(5):e819-e826. Epub 2022 Apr 22.

Davidson Orthopedics, Salt Lake City, Utah, U.S.A.

Acromioclavicular (AC) joint injuries occur with a traumatic load to the lateral aspect of the shoulder and account for 9% of all shoulder girdle injuries. Rockwood classified AC joint injuries as type I though type VI, based on severity of injury, radiographic findings, and reducibility of the AC joint. Type I and II injuries are typically managed nonoperatively, whereas type IV, V, and VI are managed operatively to address the significant soft tissue disruption, persistent AC joint instability, and apical shoulder deformation.

Treatment of Acromioclavicular Joint Instability With a Tunnel-Free Reconstruction Technique.

Arthrosc Tech 2022 May 25;11(5):e895-e901. Epub 2022 Apr 25.

McGovern Medical School, University of Texas Health Science Center at Houston, Houston, Texas, USA.

Acromioclavicular joint injuries are a common shoulder injury encountered by orthopaedic surgeons. Many different surgical techniques have been described for the operative treatment of these injuries with no single, clear gold standard technique on which surgeons agree. Among the most common complications after surgical management of acromioclavicular injuries are loss of reduction, infection, fracture of clavicle or coracoid, and need for reoperation. Read More

The effects of limb laterality and age on the inflammation and bone turnover of the acromioclavicular shoulder joint: 18F-fluorodeoxyglucose and 18F-sodium-fluoride-PET/computed tomography study.

Nucl Med Commun 2022 May 30. Epub 2022 May 30.

Department of Radiology, Hospital of the University of Pennsylvania, Philadelphia, Pennsylvania, USA.

Purpose: The acromioclavicular (AC) joint is a common site of injury and degenerative changes such as osteoarthritis (OA) of the shoulder. Physical manifestations of OA are preceded by molecular changes, detection of which may enhance early prophylaxis and monitoring of disease progression. In this study, we investigate the use of 18F-FDG and 18F-NaF-PET/CT to assess the effects of limb laterality and age on the inflammation and bone turnover of the AC shoulder joint. Read More

Differences between Coracoclavicular, Acromioclavicular, or Combined Reconstruction Techniques on the Kinematics of the Shoulder Girdle.

Am J Sports Med 2022 Jun 9;50(7):1971-1982. Epub 2022 May 9.

Department of Orthopedic Surgery and Traumatology, Ghent University Hospital, Ghent, Belgium.

Background: Although the coracoclavicular (CC) ligaments are classically reconstructed after acromioclavicular (AC) joint injuries, biomechanical studies over the past decade have indicated the importance of an additional reconstruction of the AC ligaments.

Are there differences in arthroscopic and histological features between traumatic and degenerative rotator cuff tears in elderly patients? A prospective dual-center analysis.

J Orthop Surg Res 2022 Apr 7;17(1):206. Epub 2022 Apr 7.

Department of Orthopaedic Surgery, Fukuoka University Faculty of Medicine, 7-45-1 Nanakuma, Jonan-ku, Fukuoka, 814-0180, Japan.

Background: Discriminating traumatic rotator cuff tears (RCTs) from degenerative RCTs is sometimes difficult in elderly patients because the prevalence of asymptomatic RCTs increases with age. Little intraoperative information is available on the characteristics of traumatic and degenerative RCTs in elderly patients. The purpose of this study was to compare the arthroscopic findings and histological changes of the coracoacromial ligament (CAL) between traumatic and degenerative RCTs in elderly patients.

Nonoperative Management of Traumatic Acromioclavicular Joint Injury: A Clinical Commentary with Clinical Practice Considerations.

Int J Sports Phys Ther 2022 1;17(3):519-540. Epub 2022 Apr 1.

Shoulder Center of Kentucky, Lexington Clinic.

Traumatic injuries of the acromioclavicular joint result in pain and potentially long-term alterations in scapulohumeral rhythm that occurs due to disruption of the clavicular strut function which is integral to scapular kinematics. Nonoperative treatment remains a valid option in most acromioclavicular joint injuries with the potential of minimizing pain and restoring scapulohumeral rhythm. However, few studies have provided nonoperative treatment details. Read More

The "Chiang Mai Lean Forward" Radiographic View for Acromioclavicular Joint Injuries: A Cadaveric Study.

Orthop J Sports Med 2022 Mar 21;10(3):23259671221084284. Epub 2022 Mar 21.

Department of Orthopaedics, Faculty of Medicine, Chiang Mai University, Chiang Mai, Thailand.

Background: Operative treatment is suggested for unstable type 3 acromioclavicular (AC) joint injuries; however, there is no clear consensus regarding the definition of an unstable type 3 injury. We propose a new radiographic method, the "Chiang Mai lean forward" view, to verify horizontal displacement in an unstable AC joint injury.

Hypothesis: A radiograph taken with the torso leaning forward would allow the detection of a higher proportion of AC joint injuries. Read More

Acromioclavicular joint instability on cross-body adduction view: the biomechanical effect of acromioclavicular and coracoclavicular ligaments sectioning.

BMC Musculoskelet Disord 2022 Mar 23;23(1):279. Epub 2022 Mar 23.

Department of Orthopedic Surgery, Nara Medical University, 840 Shijoutyou, Kashihara City, Nara, 634-5821, Japan.

Background: The acromioclavicular (AC) and coracoclavicular (CC) ligaments are important stabilizers of the AC joint. We hypothesized that AC and trapezoid ligament injuries induce AC joint instability and that the clavicle can override the acromion on cross-body adduction view even in the absence of conoid ligament injury. Accordingly, we investigated how sectioning the AC and CC ligaments contribute to AC joint instability in the cross-body adduction position. Read More

Clinical Evaluation and Instrumental Diagnostics in Acute Acromioclavicular Joint Dislocation.

Ortop Traumatol Rehabil 2022 Feb;24(1):1-12

Functional Diagnostics Department SI "Institute of Traumatology and Orthopedics of the NAMS of Ukraine," Kyiv, Ukraine.

Background: The aim was to improve the diagnosis of acromioclavicular joint dislocation by studying the capabilities and characteristics of clinical and instrumental diagnostic methods. The idea is expressed that modern clinical and instrumental diagnostic methods comprise a large number of techniques, but no single algorithm for diagnosing injury to the AC joint has been developed. A gold standard for investigating and diagnosing acute AC joint dislocation does not currently exist. Read More
