Q

Describe the relationship of the Radial nerve to deep brachial artery in radial (spiral groove)?

A

The radial nerve and the deep brachial artery run together through the spiral groove in the humerus and the deep brachial artery is more lateral than the radial nerve

Q

Describe the relationship of the Brachial artery to median nerve?

A

They run together for the length of the humerus and diverge at the same level that the brachial artery splits into the ulnar artery and radial artery

The median nerve diverges from the brachial artery when it runs between the 2 heads of the pronator teres (ulnar head and Humeral head)

A

Mallet Finger: avulsion of the long extensor tendon that results in hyperflexion of DIP

29
Q

Define the Dupuytren’s pathological condition

A

Dupuytren’s contracture: progressive fibrosis of the palmar aponeurosis the results in marked flexion of fingers at MP joints
