ResumoObjetivoIdentificar a inserção ulnar do ligamento colateral lateral ulnar (LCLU) com o uso da ponta do olécrano e da cabeça do rádio como parâmetros fixos para orientar a cirurgia de re- construção ligamentar.MétodosForam dissecados 13 cotovelos de cadáveres adultos frescos para estudo do LCLU. Com paquímetro digital mediram-se as distâncias entre as inserções proximal e distal do LCLU na ulna (footprint), entre a cabeça do rádio e a zona do footprint e en- tre o olécrano e a zona do footprint.ResultadosA distância média da cabeça do rádio ao ponto de inserção proximal e distal do LCLU foi de 13,6 e 22,99mm, respectivamente, da ponta do olécrano à inserção proximal e distal do LCLU foi 38,25 e 47,6mm, respectivamente, e o com- primento médio do footprint do LCLU foi de 9,35mm.ConclusõesA inserção do LCLU tem um footprint amplo com média de 9,3mm (7,5-11mm). O ponto médio de inserção ulnar situa-se a 18,2mm da cabeça do rádio e a 42,9mm da ponta do olécrano.AbstractIntroductionThe purpose of this study was to indentify the ulnar insertion of the LUCL using the olecranon tip and the radial head as parameters to guide the ligament reconstruction surgery.MethodsThirteen elbows of eight fresh cadavers were dissected for the study of the LUCL. The distances between the proximal and distal insertion of the LUCL (footprint), between the radial head and the footprint and between the olecranon tip and the footprint were measure with a digital pachimeter.ResultsThe average distance from the radial head to the proximal and distal ulnar insertion of the LUCL was 13.6 and 22.99mm, respectively. The average distance between the olecranon tip and the proximal and distal ulnar insertion of the LUCL was 38.25 and 47.6 respectively. The mean length of the LUCL footprint was 9.35mm.ConclusionsThe LUCL insertion has a wide footprint with average 9.3mm (7.5-11mm). Ulnar insertion half point be located at 18.2mm of the radial head and at 42.9mm of olecranon tip
