Multiple types of the connection between the flexor pollicis longus and the flexor digitorum profundus were described: [9] A tendinous connection between the flexor digitorum profundus of the index to the flexor pollicis longus; A muscle with a bifurcated (split into two) tendon for the thumb and index finger
two of these supply the sides of the thumb, while the third gives a twig to the first lumbricalis and is distributed to the radial side of the index finger. It also divides into two common palmar digital nerves: The first of these divides into two proper digital nerves for the adjoining sides of the index and middle fingers;
Lack of ability to abduct and oppose the thumb due to paralysis of the thenar muscles. This is called "ape-hand deformity". [3] Sensory loss in the thumbs, index fingers, long fingers, and the radial aspect of the ring fingers. Weakness in forearm pronation and wrist and finger flexion [2]
