Imaging of the Acromioclavicular Joint: Anatomy, Function, …
AC joint movements are commanded by the regional muscles. In the biomechanics literature, translational (straight line along an axis) and rotational (spinning around an axis) movements at a joint are described as taking place in the horizontal, vertical, or axial planes .
Sonographic image of a right acromioclavicular joint
Ultrasound can be used to assess joint space and detect osteophytes or other bony erosions, although the usefulness of this technique is dependent on the skill of the technician and is limited...

2023年2月5日 · Acromioclavicular joint osteoarthritis is a common degenerative condition of the shoulder.
Ultrasound of the Acromioclavicular Joint | SpringerLink
2022年1月4日 · Ultrasound (Fig. 4.23) easily highlights osteophytes on the edges of the jont space, narrowing of the space, heterogeneity of the joint disc, sometimes intra-articular osteochondromas. Joint cysts can develop.
The ultrasound assessment of osteoarthritis: the current status
In a recent review, Precerutti and colleagues (2020) stated that due to the vast number of US examinations performed to investigate shoulder pain, the AC joint should be included in the routine assessment. The authors conclude that the US can easily detect AC osteoarthritis .
Acromioclavicular Joint: The Other Joint in the Shoulder - AJR
2014年1月22日 · In a study by Strobel et al. of 50 acromioclavicular joint injections, 38% achieved pain relief, and caudal osteophytes and capsular hypertrophy were MRI predictors of response. Potential complications include infection and bleeding.
AC Arthritis - Shoulder & Elbow - Orthobullets
2022年11月10日 · AC arthritis is the most common cause of AC joint pain with repetitive microtrauma leading to the development of osteoarthritis in the AC joint. Diagnosis is made with dedicated shoulder radiographs that reveal osteophytes and joint space narrowing in the AC joint.
The acromioclavicular (AC) joint links the axial skeleton to the up- per extremity, functioning in concert with the rest of the shoulder girdle to ensure fluid arm motion (1).
Ultrasound evaluation of the acromioclavicular joint - PubMed
Conclusion: Ultrasound can detect AC joint changes reliably. It is able to exclude joint inflammation. Effusion in the AC joint may reflect inflammation, but may also be a sign of degeneration.
Acromioclavicular Joint - Radiology Key
2017年1月21日 · The most common findings are joint space narrowing and marginal osteophytes secondary to osteoarthritis. If there is widening of the ACJ, considerations include inflammation and trauma. Distal clavicle resection may mimic widening of the ACJ, but a careful clinical history usually suffices to reach the correct diagnosis (figure 5-5).
