Appreciate the pic of the shouler
What lesion can occur due to anterior dislocation of the shoulder ?
Bankart lesion - is an injury of the anterior (inferior) glenoid labrum
Following an anterior dislocation of the shoulder what is the most common nerve injury and where does it get injured ?
Axillary nerve injury - gets compressed at the quadrangular space
What are the named nerves in the brachial plexus and how do they relate to each other ?
What are the signs of a frozen shoulder ?
Global loss of ROM esp external rotation
What nerve supplies the anterior compartment of the arm ?
Musculocutaneous nerve
What nerve supplies the posterior compartment of the arm ?
Radial nerve
What nerve supplies the anterior compartment of the forearm ?
- All median nerve
- Except FCU & ulnar half of FDP = ulnar n

So Long To Pinky Here Comes The Thumb

Following a suprachondylar fracture what is there risk of ?
Risk brachial artery occlusion & median nerve injury
Where does the problem in tennis elbow occur ?
Tear in the extensor origin to the lateral epichondyle
Where does the problem in golfers elbow occur ?
Tear in the flexor origin in the medial epichondyle
What does tenderness in the floor of the anatomical snuffbox suggest ?

Describe what Dupuytren’s Contracture is
It is a pathology affecting the palmar fascia. It causes thickening and shortening (contracture) leading to fixed flexion deformities, of in particular, the ring and little fingers.
Describe the lymph drainage in the upper limb
- Lymph vessels following the basilic vein drain into the cubital lymph nodes ===> axillary lymph nodes
- Vessels following the cephalic vein drain directly into axillary lymph nodes
Axillary ===> Subclavian lymphatic trunk
Right subclavian trunk ===> R lymphatic duct ===> Right venous angle
Left subclavian trunk ===> directly into thoracic duct
In the axilla there is 5 main groups of axillary lymph nodes what are they ?
- Pectoral (anterior)
- Subscapular (posterior)
- Humeral (lateral)
- Central
- Apical
