The therapist is palpating the shoulder of a patient. As he carefully laterally rotates the arm, in what sequence will the palpable structures be felt in the proximal humerus?

• Greater tuberosity > biceps, long head > lesser tuberosity

• Lesser tuberosity > biceps, short head > Greater tuberosity

• Greater tuberosity > biceps, short head > lesser tuberosity

• Lesser tuberosity > biceps, long head > Greater tuberosity

During circling motion of the arm, the axis can be found at the:

• Acromioclavicular joint

• Sternoclavicular joint

• Glenohumeral joint

• NOTA

• AOTA

A biker fell on his left shoulder during a sports event. After medical examination by a physician, it was reported that the athlete's shoulder was 'separated.' Pain and swelling was noted at the point of the shoulder accompanied by a 'step-off' deformity. What might have caused this deformity?

• Tear of the costoclavicular ligament

• Tear of the acromioclavicular ligament

• Tear of the coracohumeral ligament

• Both A and B

• Both B and C

Which of the following is true regarding the inferior glenohumeral ligament?

• It limits IR and ER above 90 degrees

• Thickens on MRI viewing during adhesive capsulitis

• Covers the subacromial bursa and

• Serves as the roof of the bicipital groove to hold the biceps tendon

• Limits inferior translation of the humerus during adduction

Which of the following ligaments prevents superior translation of the humeral head?

• Coracohumeral Ligament

• Transverse humeral Ligament

• Coracoclavicular Ligament

• Coracoacromial Ligament

• Inferior Glenohumeral Ligament
