Introduction: incidence of injuries due to a wide number of factors and its morphology may be one of the underlying factors as scientific literature points out. The connective tissue component of the attachment of hamstring muscles is not well known. For this reason the aim of this study is to describe the anatomy and histology surrounding the proximal attachment of the hamstring muscles and its direct anatomic relations.The proximal attachment of hamstring muscles has a very high Methods: Forty-eight cryopreserved lower limbs have sequentially been studied by means of dissection, anatomical sections and histology. Results: All specimens studied presented an annular connective tissue structure that resembles a retinaculum, which covers and adapts to the attachment of hamstring muscles on the ischial tuberosity. Conclusion: The results show how this retinaculum is continuous with the long head of biceps femoris muscle, however there is a layer of loose connective tissue between the retinaculum and the semitendinosus muscle. Furthermore, this structure receives expansions of the anterior epimysium of the gluteus maximus muscle. Keywords: hamstring proximal attachment, hamstring injury, retinaculum, fascia.
