Use of gracile and semi-tendinosus tendons (GRAST) for the reconstruction of irreparable rotator cuff tears
BMC Musculoskeletal Disorders Apr 09, 2021
Protais M, Laurent-Perrot M, Artuso M, et al. - This study was undertaken to ascertain if a braided graft of gracilis and semitendinosus could fill a loss of tendon substance from an irreparable rupture of the supra- and infraspinatus, by fixing the graft to the greater tuberosity and the spine of the scapula. Researchers performed a cadaveric study including the use of ten specimens. Where current grafting techniques only fill a tendinous defect, this procedure simplifies the medial fixation and restores the musculotendinous chain. The results demonstrate that the transplant could have a subacromial “spacer” effect and lower the humeral head. Moreover, this anatomical study gives the way for clinical experimentation.
