![]() ![]() Froment sign = inability to pinch paper between thumb and index finger without bending of the thumb → indicates ulnar nerve palsy affecting adductor pollicis. Patient utilizes flexor pollicis longus.Left and right rotation of the atlantoaxial joint occurs in the. Adducts the thumb at the 1st CMC joint (i.e., from the abducted position, moves the thumb posteriorly back toward the palm). Abduction and adduction of the shoulder occur in the coronal plane, and about the sagittal axis.Right: Wartenberg sign note the abducted positioning of the 5th finger. The net result is the extensor digiti minimi remains unopposed, with the abduction positioning favored. There is also attenuated function of the abductor digiti minimi (also ulnar nerve), but the effect of loss of adduction function of palmar interossei is more significant in pinky position. Nautilus Nitro EVO features patent pending 5 lb Increment weight stack, which is perfect for slight strength gains and ideal for newcomers, women and the. ![]() ![]() Wartenberg sign → ulnar nerve palsy resulting in attenuated function of palmar interossei → loss of pinky adduction component → pinky’s normal position is more abducted.Abduction moves the limb laterally away from the midline of the body, while adduction is the opposing movement that brings the limb toward the body or across the midline. Note that the pinky is adducted by the palmar interossei, but it is not abducted by the dorsal interossei the abductor digiti minimi abducts the pinky. Abduction and adduction motions occur within the coronal plane and involve medial-lateral motions of the limbs, fingers, toes, or thumb.Adduct the pinky, ring, middle, and index fingers (i.e., the pinky, ring, and index movement toward from the middle finger.Movement of the middle finger medially is referred to as ulnar abduction movement of the middle finger laterally is referred to as radial abduction. Should be noted that the middle finger has two dorsal interossei attachments and no palmar interossei attachments.PAD DAB– mnemonic for memorizing actions of dorsal vs palmar interosseous functions – Palmar ADduction, Dorsal ABduction.Abduction is any motion of the limbs or other body parts that pulls away from the midline of the body. Innervated by deep branch of ulnar nerve. So in people with normal eyes, when one eye is adducted, the other abducts.Insert on the proximal phalanges and extensor expansions (specialized connective tissue).Abduct the ring, middle, and index fingers (i.e., the ring and index movement away from the middle finger + the middle finger movement radially).Innervated by the deep branch of ulnar nerve. Adduction/abduction and circumduction take place at the shoulder, hip, wrist, metacarpophalangeal, and metatarsophalangeal joints.Enables grasping of large objects while the fingers are outstretched. Adduction, abduction, and circumduction take place at the shoulder, hip, wrist, metacarpophalangeal, and metatarsophalangeal joints.Abducts the pinky at the 5th carpometacarpal joint. Adduction is a motion that pulls a structure or part towards the midline of the body, or towards the midline of a limb, carried out by one or more adductor muscles. ![]()
