En ortopedia, la lesión de Bankart es una rotura de la parte anteroinferior del reborde glenoideo o labrum glenoideo de la escápula, a consecuencia de una luxación anterior de hombro. Perthes lesion is variant of Bankart lesion, presenting as an anterior glenohumeral injury that occurs when the scapular periosteum remains intact but is stripped. Sometimes, glenoid bone loss accompanies a bony fragment, which is called a bony Bankart lesion. This is observed in.

Bankrat the labrum may be normally positioned, functionally it no longer provides any stability to the humeral head, mainly as a result of impairment of the normal stabilizing influence of the inferior glenohumeral ligament.
It should not be confused with Perthes disease of the hip. As the labrum is often normally positioned it may be difficult to appreciate, especially if scarring obliterates the space deep to the labrum. The presence of a joint effusion or MR arthrogram help in the detection of this lesion by demonstrating fluid extending beneath the labrum and filling the space between the elevated periosteum anteriorly and the scapula posteriorly.
Imaging the joint in the ABER position is helpful in increasing detection rates. Although scarring may develop making detection both on imaging and arthroscopy difficult to interpret, the shoulder remains unstable, unless re-attachment of the labrum is performed.
It is named after Georg Clemens Perthes German surgeon, who first described the lesion in A number of lesions are closely related have similar appearances: A sublabral recess can be a differential in some situations.
