Patients can present with non-specific shoulder pain and swelling. A visible deformity is uncommon. Low-grade injuries can often be overlooked both clinically and radiologically. Pain may be provoked with the cross-body and/or O'Brien active compression test 9. Pathology. There are two main mechanisms of acromioclavicular joint injury 7,9:

The AC joint is a plane synovial joint comprised of the acromial process of the scapula and the lateral end of the clavicle. A fibrous capsule surrounds the joint and there may be a …

3 GRADES OF SEPARATED SHOULDER. Grade I- mild shoulder separation. This involves a sprain of the AC ligament that does not move the collarbone and looks normal on X-rays. Grade II – a tear in the AC ligament, and/or a sprain or slight tear in the coracoclavicular (CC) ligament. This puts the collarbone slightly out of …

However, although a reduction of symptoms can be achieved through nonoperative treatment methods for low-grade injuries, 40 residual deficits in function …

VA Disability Rating for Acromioclavicular Joint Separation. Under § 4.71a, Diagnostic Code 5203, the VA assigns shoulder separations a 20% rating for either arm, regardless of severity. Range of motion — The less you can lift or bend your shoulder, the higher the disability rating you will likely receive.

Low grade injuries (Type I and II) involve limited injury to the AC joint only and should be managed conservatively. In contrast, high grade injuries (Type IV, V, and VI) involve injury to the AC joint, coracoclavicular (CC) ligaments, and overlying fascia and should thus be managed surgically. ... A type III separation involves injury to both ...

In the present investigation, magnetic separation studies using an induced roll magnetic separator were conducted to beneficiate low-grade ferruginous manganese ore. The feed ore was assayed to ...

Present investigation includes the magnetizing roasting of low-grade iron ore fines followed by grinding and beneficiation using magnetic separation. The hematite iron ore used in the investigation contains 53.17% T Fe, 10.7% SiO2, and 4.5% Al2O3. Powdered bituminous coal of 210 μm size with an ash content of 12.5% and fixed carbon …

An acromioclavicular joint injury, otherwise known as a shoulder separation, is a traumatic injury to the acromioclavicular (AC) joint with disruption of the acromioclavicular ligaments and/or coracoclavicular …

In the present investigation, magnetic separation studies using an induced roll magnetic separator were conducted to beneficiate low-grade ferruginous manganese ore. The feed ore was assayed to contain 22.4% Mn and 35.9% SiO2, with a manganese-to-iron mass ratio (Mn:Fe ratio) of 1.6. This ore was characterized in detail using different …
