Scaffolds in the management of massive rotator cuff tears: current concepts and literature review

[摘要] The rotator cuff (RC) plays a significant role in shoulder biomechanics and is predisposed to injury and degenerative changes because of its location and blood supply.1 The prevalence of RC tears is 34% in the general population and is more prevalent in the elderly population (54% in those > 60 years of age).2,3 A study on the natural history of RC tears has shown that asymptomatic rotator cuff tears will become symptomatic and that the size of the tear will progress with time.4 Massive RC tears could alter glenohumeral kinematics leading to humeral head migration, cuff tear arthropathy and pseudo paralysis of the shoulder.4,5 Surgical management of massive cuff tear is challenging and the re-rupture rate has been reported in the literature as between 11%6 and 94%.
