Question

which of the following nerve injury leads to wrist drop?​

Answer 1

Explanation:

Wrist drop is caused by damage to the radial nerve, which travels down the arm and controls the movement of the triceps muscle at the back of the upper arm, because of several conditions. This nerve controls the backward bend of wrists and helps with the movement and sensation of the wrist and fingers.

Answer 2

Answer:

Wrist drop is a disorder caused by radial nerve palsy. Because of the radial nerve's innervation of the extensor muscles of the wrist and digits, those whose radial nerve function has been compromised cannot actively extend them. As such, the hand hangs flaccidly in a position of flexion when the patient attempts to bring the arm to a horizontal position. Causes of wrist drop can range for penetrative trauma to external compression (Saturday night palsy) to systemic nutritional deficiencies. Treatment can range from none to surgery, depending on the nature and extent of the injury to the radial nerve.

So your answer is Radial nerve palsy
