acromonioclavicular joint separation
An acromioclavicular joint (ACJ) separation is classically described by the mechanism of action of falling on the tip of the shoulder with the arm tucked (adducted). Patients with ACJ injuries will have restricted range of motion secondary to pain, especially with overhead movement and axial traction applied to the arm. The most reliable physical examination test for acromioclavicular joint pathology is the cross-body adduction test.

METS!
105
acrominoclavicular joint separation
Acromioclavicular joint injuries are common, and range from a mild sprain to complete disruption of the acromioclavicular joint (ACJ), with injury to the surrounding structures. The mechanism of injury usually involves either a direct blow, or a fall onto the shoulder with an adducted arm. Physical examination finding include pain, swelling, prominence of the clavicle, and point tenderness over the ACJ.
106
bicipital tendonitis
Yergason's test is used to evaluate for a biceps tendon injury. It involves applying resistence to arm supination with the elbow flexed. Pain of the long head of the biceps is a positive test.
107
axial loading with rotation (MENISCAL )
. Axial loading with rotation
Catching and locking of the knee, with a positive McMurray's test suggest that this patient has a meniscal injury. The most common mechanism causing this type of injury is axial loading with rotation, in which the patient twists on a weight-bearing knee. It is common in football, soccer, and basketball players.
108
A 3 year old boy is brought to the clinic by his mother. Up to this point he has been developmentally normal, but is now having trouble rising from the floor. Physical exam shows hip girdle weakness, enlargement of the distal muscles of the leg, and atrophy of the proximal thigh muscles. Lab studies reveal an elevated serum creatinine kinase. Which of the following is this boy’s most likely diagnosis?
Duchenne's muscular dystrophy
109
motor test for median nerve
thumb opposition
110
bicipital tendonitis
E. Bicipital tendonitis
The Yergason test is done to evaluate for bicipital tendonitis. The test is done by having the patient flex their elbow to 90 degrees, the examiner then applies downward pressure on the patients forearm. The patient is then instructed to attempt to supinate against resistance. Eliciting pain with this movement is indicative of bicipital tendonitis.
