High impact information on Acromioclavicular Joint

• OBJECTIVE: To evaluate radiographically the acromioclavicular joint space in patients with long-term rheumatoid arthritis (RA) [1].
• Four parameters were evaluated: the angle of anterior slope of the acromion in the midsagittal and lateral-sagittal planes, lateral acromial angulation in the coronal plane, and the presence or absence of medial encroachment in the acromioclavicular joint [2].
• Cystic distension of the acromioclavicular joint in calcium pyrophosphate dihydrate crystal deposition disease [3].
• Acute gout involving the acromioclavicular joint following treatment with gemfibrozil [4].
• The diagnosis was confirmed radiographically with simple plain films and clinically by the injection of local anaesthetic (xylocaine 2%) that lead to the exclusion of any other concomitant pathology of the acromioclavicular joint and the anterior subacromial space [5].

Anatomical context of Acromioclavicular Joint

• CONCLUSIONS: The titanium Bosworth screw restored strength to the acromioclavicular joint equivalent to the intact coracoclavicular ligament; however, the bioabsorbable PLLA screw fixation was significantly weaker than the intact ligaments and the Bosworth repair [6].

Associations of Acromioclavicular Joint with chemical compounds

• The suprascapular nerve (SSN) originates from the C5 and C6 nerve roots and provides sensation for the posterior shoulder capsule, acromioclavicular joint, subacromial bursa, and coracoclavicular ligament [7].

Gene context of Acromioclavicular Joint

• In fractures with a small peripheral fragment or with an associated separation of the acromioclavicular joint, PDS-banding is a valuable technique for stabilization [8].
• One patient with an ABC adjacent to the distal femoral physis had growth disturbance and a second who had an extensive acromial lesion had mild degenerative changes of the acromioclavicular joint [9].

Analytical, diagnostic and therapeutic context of Acromioclavicular Joint

• This case broadens the differential diagnosis of acute acromioclavicular joint arthritis; further studies are needed to determine if there is a causal relationship between use of gemfibrozil and an acute attack of gout [4].
