Background

Acromioclavicular dislocation is one of the common clinical injuries, accounting for about 9% of shoulder injuries, and about 9.2 out of 1 000 people occur acromioclavicular dislocation every year. There are many surgical options for acromioclavicular dislocation, including Kirschner wire, tension band, hook plate, etc. However, according to the anatomical characteristics of the acromioclavicular joint, the main structures to maintain its stability are the acromioclavicular ligament and the coracoclavicular ligament, which also includes the trapezoid ligament and the conical ligament. Therefore, reconstruction of the coracoclavicular ligament at the anatomical position has the advantage of biomechanics. Its strength is closer to that of the coracoclavicular ligament itself, which has gradually become a new method for the clinical treatment of acromioclavicular dislocation. Patients with coracoclavicular ligament reconstruction at non-anatomic locations were found to have tunnel enlargement during follow-up. Tunnel enlargement can increase the risk of coracoid process or clavicle fracture, further leading to loss of reduction and redislocation after surgery, which rarely attracts doctors' attention in clinical practice. Therefore, to improve surgical skills, reduce postoperative complications, and relieve patients' pain and economic burden, it is of certain importance to study the coracoclavicular ligament anatomy.

Objective

To explore the feasibility and clinical significance of magnetic resonance imaging (MRI) imaging in measuring coracoclavicular ligament anatomical data.

Methods

From June 2020 to May 2021, 54 patients (36 males and 18 females) with a mean age was 39.76 years underwent shoulder joint MRI. The PACS software was used to measure the coracoclavicular ligament data, and the SPSS23 was used to analyze and compare the data between males and females. All patients were divided into three groups according to ages: 18-44 years old group, 45-59 years old group, and≥60 years old group, and the data differences were compared between groups. Pearson correlation analysis was used to calculate the relationship between the coracoclavicular ligament lengths, widths, distances to the distal clavicle, and the body heights and weights.
