To test the strength and function of flexor pollicis brevis, sit in a chair with one hand resting on a flat surface and your palm facing up. Place your opposite hand on the fleshy section of palm at the base of your thumb and apply gentle pressure. Flex (bend) your thumb against that pressure Function of the Flexor Pollicis Brevis The flexor pollicis brevis muscle flexes the thumb at the metacarpophalangeal joint and medial rotation of the 1st metacarpal bone at the carpometacarpal joint. Upper Extremity Muscle Atla Abductor pollicis brevis also facilitates the movement of the thumb towards the fingertips in the carpometacarpal joint (opposition) and flexion in the metacarpophalangeal joint. All of the aforementioned functions of this muscle are of great significance for the proper functioning of the hand , such as grasping round objects or carrying out tasks that demand precision (e.g. writing and sewing) Abductor pollicis brevis, tummens korta utåtförare, ligger ytligast av handens thenarmuskler. Muskeln har sitt ursprung på os scaphoideum, os trapezium och flexor-retinaklet. Sedan löper muskeln distalt till sitt fäste lateralt på basen av tummens proximala falang (via det radiala sesambenet)

Function: The adductor pollicis muscle adducts the thumb toward the index finger, the opponens pollicis opposites the thumb pad across the palm to touch the pads of the ring or little fingers; the flexor pollicis brevis muscle flexes the thumb toward the palm; and the abductor pollicis brevis muscle abducts the thumb away the palm. Trigger thumb is a simple term for stenosing flexor tenosynovitis of the thumb. This is a narrowing of the flexor tendon sheath which causes a clicking or popping sensation on attempted extension of the thumb. Flexion is normally enabled by the extrinsic flexor pollicis longus (FPL) and intrinsic flexor pollicis brevis (FPB) In conclusion, we believe in that flexor pollicis brevis adductorplasty may be an alternative method for restoration of adductor pollicis muscle function in ulnar nerve paralysis.
