“…Similarly, the trapezoid originates on the superomedial surface of the coracoid, anterior to the conoid, and travels superolateral to insert narrowly on the clavicular trapezoid line, anterior to the conoid tubercle. 16 The diverging course and distinct attachments of both ligaments argues individual function that must be considered during surgical reconstruction. Rios et al determined that reliable CC ligament clavicular insertions could be calculated as percentages of total clavicular length-the trapezoid and conoid attaching 17% and 31% of the total clavicular length from the distal end, respectively.…”

“…Rios et al determined that reliable CC ligament clavicular insertions could be calculated as percentages of total clavicular length-the trapezoid and conoid attaching 17% and 31% of the total clavicular length from the distal end, respectively. Chahla et al 16 quantitatively found that the CC ligament clavicular insertion is on average 15.7 mm from the lateral joint line and the footprint spans an average length of 25.6 mm on the clavicle. Additionally, mean distances from the coracoid apex to the center of the trapezoid and conoid ligaments are 27.0 ± 3.3 mm and 33.9 ± 3.3 mm, respectively.…”

Injuries to the acromioclavicular (AC) joint are common and mostly involve younger, male individuals. Whereas the majority of AC joint dislocations can be treated nonoperatively with a trial of immobilization, pain medication, cryotherapy, and physiotherapy, there are patients that do not respond well to conservative management and may require surgical treatment. Identifying and treating these patients according to the type and chronicity of AC joint dislocation is paramount. To date, a myriad of surgical techniques have been proposed to address unstable AC joint dislocations and are indicative of the uncertainty that exists in optimal management of these injuries. Historically research has focused on the restoration of the coracoclavicular ligament complex. However, recently the importance of the acromioclavicular capsule and ligaments has been emphasized. This review aims to provide the reader with an overview of current treatment strategies and research, as well as future perspectives.

“…Coracoid length and coracoid deviation angle were obtained by the apex and base of the coracoid process as described by Chahla et al 31 The line segment from the coracoid apex to the anterolateral corner and posterolateral corner of the acromion determined the CA arch and the CA base length and angle, respectively. These distances were normalized to the radius of the best-fit circle of the inferior glenoid to compensate for size differences between scapulae.…”

Variation in the shape of the glenoid and periarticular anatomy of the scapula has been associated with shoulder pathology. The goal of this study was to identify the modes of shape variation of periarticular scapular anatomy in relation to the glenoid in nonpathologic shoulders. Computed tomography scans of 31 cadaveric scapulae, verified to be free of pathology, were three‐dimensionally reconstructed. Statistical shape modeling and principal component analysis identified the modes of shape variation across the population. Corresponding linear and angular measurements quantified the morphometric variance identified by the modes. Linear measures were normalized to the radius of the inferior glenoid to account for differences in the scaling of the bones. Five modes captured 89.7% of total shape variation of the glenoid and periarticular anatomy. Apart from size differences (mode 1: 33.0%), acromial anatomy accounted for the largest variation (mode 2: 32.0%). Further modes described variation in glenoid inclination (mode 3: 11.8%), coracoid orientation and size (mode 4: 9.0%), and variation in coracoacromial (CA) morphology (mode 5: 3.1%). The average scapula had a mean acromial tilt of 49 ± 7°, scapular spine angle of 61 ± 6°, the glenoid inclination of 84 ± 4°, coracoid deviation angle of 26 ± 4°, coracoid length of 3.7 ± 0.3 glenoid radii, and a CA base length of 5.6 ± 0.5 radii. In this study, the identified shape modes explain almost all of the variance in scapular anatomy. The acromion exhibited the highest variance of all periarticular anatomic structures of the scapula in relation to the glenoid, which may play a role in many shoulder pathologies.

“…Although this does not take into account anatomic variables, this limitation does not appear to be catastrophic to the present study given that the authors' reported distance from lateral clavicular edge to both the medial and lateral clavicular holes was close to those previously reported in the literature. [6][7][8][9] Achieving stable fixation after injury to the CC joint is vital in allowing athletes to return to a high level of sport and "weekend warriors" to the activity level at which they desire to function. The understanding of the CC ligament anatomy has evolved over the past decade.…”

“…The CC ligaments' footprint on the clavicle is broad, and therefore recreating its footprint with a single point of fixation during CC ligament repair has been associated with loss of reduction and inferior function. 2,6,8,9 Double-bundle AC joint reconstruction provides significantly better restraint to AP translation and trends toward superior rotational control compared with SB reconstruction. 1 There is a broad spectrum of surgical treatments of AC joint instability.…”

Injuries to the acromioclavicular joint are common across all levels of sport and activity. Overall, a consensus exists regarding Rockwood grade I and II injuries (conservative approach) and Rockwood grades IV to VI (best treated surgically). However, grade III injuries are heterogeneous and thus respond differently to nonoperative and operative treatment. Regardless of the acromioclavicular injury grade, these are widely prevalent injuries, and there is a lack a consensus as to which operative fixation methods yield the best outcomes for patients. Although K-wires and plates were historically used to achieve rigid fixation, recent evidence supports the use of soft tissue grafts to reconstruct the coracoclavicular ligaments and restore vertical and anteroposterior and rotational stability with a more biological approach.
