Answer :
The condition that results from a rupture of the flexor digitorum profundus tendon is a. Jersey finger.
The other two conditions you mentioned are related to different tendons or structures in the hand:
b. Boutonniere deformity occurs when there is damage to the central slip of the extensor tendon.
c. Mallet finger results from a rupture or avulsion of the extensor tendon at the distal interphalangeal joint.
Jersey finger is the result of a rupture of the flexor digitorum profundus tendon. It occurs when the tendon is torn or avulsed from its insertion point on the distal phalanx (the bone at the tip of the finger). This injury typically happens when the finger is forcefully extended while the person is gripping an object, such as an opponent's jersey in sports like American football.
Jersey finger is characterized by the inability to flex the affected finger at the distal interphalangeal joint (DIP joint). The person may experience pain, swelling, and bruising, as well as difficulty using the finger for gripping or grasping objects. The finger may appear straight or slightly extended at the DIP joint.
Treatment for Jersey's finger usually involves surgical repair to reattach the torn tendon to the bone. If left untreated, it can lead to long-term functional impairment and weakness in finger flexion. Rehabilitation exercises and physical therapy are important for recovery and restoring finger function after surgical intervention.
Therefore, the correct option is A.

A rupture of the flexor digitorum profundus tendon causes Jersey finger, characterized by the inability to flex the fingertip, and the wrist flexors originate from the medial epicondyle of the humerus. The correct option is: a. Jersey finger
A rupture of the flexor digitorum profundus tendon results in a condition known as Jersey finger. This injury is characterized by the inability to flex the fingertip because the tendon tears away from the bone, often taking a small piece of bone with it. It typically occurs when an athlete's finger catches on another player’s clothing, such as grabbing a jersey, which causes forceful extension of the finger while in active flexion. Jersey finger is different from Boutonniere deformity and Mallet finger, which involve different tendons and mechanisms of injury.
The origin of the wrist flexors, including the flexor digitorum profundus, is at the medial epicondyle of the humerus, not the lateral epicondyle, carpal bones, or deltoid tuberosity.
