Lack of efficacy of ‘weighted’ radiographs in diagnosing acute acromioclavicular separation

Ultrasound of the coracoclavicular ligaments in the acute phase of an acromioclavicular disjonction: Comparison of radiographic, ultrasound and MRI findings

“…Radiographs alone are not sufficient to evaluate the integrity of the coracoclavicular ligaments. Bossart et al found that grade 2 injuries are difficult to differentiate from grades 3 injuries on radiographs [22]. Our results support Bossart et al's findings: in 17 of the 47 cases, both ultrasound imaging and MRI found grade 3 injuries that may require surgical treatment, while these cases were classified as grade 2 injuries on radiographs.…”

The Normal Acromioclavicular Joint: An In Vivo Multidetector CT (MDCT) Morphometric and Biometric Cross Sectional Feasibility Study

“…Proper grading of the AC injuries relied upon detection of joint widening on conventional radiography [3]. However, inconsistency about imaging planes and debate of applying stress [15][16][17]; especially in traumatized patients; bias the sensitivity and specificity of this imaging tool. On the other hand, role of Computed Tomography (CT) is well established in skeletal trauma [10,11].…”

Missed type IV AC joint dislocation: A case report

“…[3][4][5] In the case we describe, it is likely that an oblique radiograph would have aided diagnosis.…”
