Anterior interosseous nerve: anatomical study and clinical implications
ConclusionThe fibrous arches formed by the humeral and ulnar heads of the pronator teres muscle, the fibrous arch of the flexor digitorum superficialis muscle, and the Gantzer muscle (when hypertrophied and positioned anterior to the anterior interosseous nerve), can compress the nerve against deep structures, altering its normal course, by narrowing its space, causing alterations longus and flexor digitorum profundus muscles.ResumoObjetivoAnalisar as relações anatômicas e as variações do nervo interósseo anterior e suas implicações clínicas. A paralisia completa do nervo interósseo anterior resulta na incapacida...
