Abstract

OBJECTIVESTo put forward an anatomical description of the innervation of the elbow capsule, illustrated through morphological analysis on dissections.METHODSThirty elbows from fresh fixed adult cadavers aged 32–74 years, of both sexes, were dissected.RESULTSAmong the dissected arms, we observed that the median nerve did not have any branches in two arms, while it had one branch in five arms, two branches in two arms, three branches in ten arms, four branches in nine arms and five branches in two arms. The radial nerve did not have any branches in two arms, while it had one branch in two arms, two branches in nine arms, three branches in ten arms, four branches in five arms and five branches in two arms. The ulnar nerve did not have any branches in three arms, while it had one branch in six arms, two branches in four arms, three branches in five arms, four branches in seven arms, five branches in four arms and six branches in one arm.CONCLUSIONSWe observed branches of the radial, ulnar and medial nerves in the elbow joint, and a close relationship between their capsular and motor branches.OBJETIVOSPromover a descrição anatômica da inervação da cápsula do cotovelo com ilustração por meio da morfologia das dissecações.MÉTODOSForam dissecados 30 cotovelos de cadáveres adultos frescos e fixados, com idade entre 32 e 74 anos, de ambos os sexos.RESULTADOSObservamos, dentre os braços dissecados, dois com nenhum ramo do nervo mediano, cinco com um ramo, dois com dois ramos, 10 com três ramos, nove com quatro ramos e dois com cinco ramos. Quando se trata do nervo radial, dois braços não apresentaram ramos, dois mostraram dois ramos, nove continham dois ramos, 10 contaram com três ramos, cinco tinham quatro ramos e dois tinham cinco ramos. Em relação ao nervo ulnar, tivemos três braços sem ramos articulares, seis com um ramo, quatro com dois ramos, cinco com três ramos, sete com quatro ramos, quatro com cinco ramos e um com seis ramos.CONCLUSÕESConstatamos ramos do nervo radial, ulnar e medial na articulação do cotovelo, assim como a relação próxima entre os seus ramos capsulares e motores.
