PURPOSE: To determine biomechanical properties of the superior labrum-biceps tendon complex submitted to continuous and sudden mechanical strain.
METHODS: Eighteen shoulder specimens from 15 unclaimed corpses, ages ranging from 20 to 40 years, were submitted to continuous or sudden tensile tests using 3 different traction machines. Shoulders presenting signs of degenerative diseases or preexisting traumatic lesions were excluded.
RESULTS: Rupture of the distal portion of the long hand of the biceps occurred when stretching forces reached 290N in continuous traction and 384N in sudden traction. No labral-complex lesions were observed.
CONCLUSION: Either a simple continuous or a sudden uniaxial traction of the arm do not play a role in the genesis of superior labrum anterior-posterior (SLAP) lesions in the shoulder joint.
