AI Article Synopsis
- The study focused on the anatomy of trapezoid and conoid ligaments in the acromioclavicular joint by examining 40 shoulders from 20 cadavers.
- The trapezoid ligaments were found to start 2 cm from the coracoid process and extend toward the clavicle, while the conoid ligaments began at the medial margin of the coracoid and directed toward the clavicle’s conoid tubercle.
- These detailed anatomical findings are crucial for improving surgical reconstruction techniques for acromioclavicular joint dislocations.
Article Abstract
Purpose: The treatment for the acromioclavicular joint dislocations has focused on anatomic restoration of the coracoclavicular ligaments. We reviewed the detailed anatomy of trapezoid ligaments and conoid ligaments using cadavers.
Methods: The subjects were 40 shoulders of the 20 cadavers. We investigated the distributed direction and attachment sites of both trapezoid and conoid ligaments.
Results: The trapezoid ligaments began at about 2 cm away the central point of the distal coracoid process and directed toward the undersurface of the clavicle. The attachments extended from 13 to 26 mm in sagittal dimension and from 13 to 15 mm in coronal dimension. The conoid ligaments began at the medial posterior margin of the coracoid process and directed toward to the conoid tubercle in the clavicle. The attachments extended from 15 to 30 mm in sagittal dimension and from 3 to 6 mm in coronal dimension.
Conclusion: The findings are important indices for the accurate reconstruction of the coracoclavicular ligaments in acromioclavicular joint dislocations.

Distal augmentation in unstable distal clavicle fractures: a retrospective cohort study of 101 cases.

Introduction: The optimal management strategy for unstable distal clavicular fractures remains controversial. Recent studies on plate techniques have reported good-to-excellent outcomes with no serious complications. The questions are that: (1) Does the use of wire augmentation with locking plate in distal part (distal wire augmentation) reduce radiographic loss of reduction (RLOR) and get earlier bony union in distal clavicular fractures? (2) Which fixation methods are associated with a higher incidence of acromioclavicular (AC) joints arthritis or subluxation? We collected and analyzed clinical studies on different plate fixation methods for unstable fractures to identify the best surgical modality.

Article Synopsis
- Clavicle fractures are common in emergency departments, while acromioclavicular (AC) joint injuries are rare and even more so when combined with clavicle fractures.
- A 29-year-old male patient experienced both an AC joint dislocation and a midshaft clavicle fracture, leading to surgical treatment that resulted in excellent recovery and range of motion after one year.
- The case highlights the rarity of this combination of injuries and stresses the importance of timely diagnosis and investigation to achieve favorable functional outcomes, although there's still no agreement on the best treatment approach.
A new classification system for distal clavicle fractures: based on fracture location and ligament integrity.

Department of Orthopedics, The First Affiliated Hospital of Nanjing Medical University, 300 Guangzhou Road, Nanjing, Jiangsu, 210029, People's Republic of China.
Introduction: Although various classification systems have been introduced for the description of distal clavicle fractures, there is no consensus on the best classification system that is helpful in determining treatment and prognosis. The objective of this study was to establish a new classification system for distal clavicle fractures and to verify the reliability of the new classification system by evaluating the inter- and intraobserver agreement.
Materials And Methods: A total of 1075 consecutive patients with distal clavicle fractures were selected from five university-affiliated hospitals between 2012 and 2022.
High-energy injuries, combined ligamentous injuries, and joint incongruity as predictors of postoperative shoulder dysfunction in AC joint dislocation surgery.

Department of Orthopaedics, Tongji Hospital, Tongji University, Shanghai, China.
Objective: To identify risk factors associated with postoperative shoulder joint dysfunction in patients who underwent surgical intervention for acromioclavicular (AC) joint dislocation, with the aim of enhancing preoperative counselling, surgical planning, and postoperative management to optimize functional outcomes.
Methods: Patients who underwent surgery for AC joint dislocation between January 2018 and January 2023 at a hospital orthopaedic centre were enrolled into this retrospective study. Inclusion criteria were patients aged ≥18 years with a documented AC joint dislocation who underwent surgical treatment and had a minimum follow-up period >1 year.

Article Synopsis
- The study aimed to evaluate the effectiveness of using an Endobutton plate combined with high-strength suture Nice knot fixation for treating distal clavicular fractures along with coracoclavicular ligament injuries.
- It involved a retrospective analysis of 43 patients, comparing two treatment methods: the experimental group (high-strength Nice knot suture fixation) and a control group (acromioclavicular Kirschner wire fixation), over an average follow-up period of about 20 months.
- Results showed that while the experimental group had significantly faster bone healing times, there were no notable differences in coracoclavicular space increase, demographic data, or shoulder function improvement between the two groups.
