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.

Lee for their support in the serial works on shoulder instability.
About Hmbro Go ad-free. MR imaging and MR arthrographic findings with surgical correlation. A Clockwise approach to the labrum is the easiest way to diagnose labral tears and to differentiate them from normal labral variants.
A constrained articular surface. Wien klin Wochenschr Suppl ; Shoulder stability The basic concept of shoulder stability is explained in the first section of this article so that the following explanation of bony stability will be better and more easily understood by the readers.
‘On-track’ and ‘off-track’ shoulder lesions
On MR-arthrography it may be difficult to depict the osseus fragment. All that is needed is a ruler.
Perthesa German Surgeon and X-Ray diagnostic pioneer who first described the lesion in Preoperative analysis of the Hill-Sachs lesion in anterior shoulder instability: Clinical validation of the glenoid track concept in anterior glenohumeral instability.
Lesiin tears typically extend from the 10 to the 2 o’clock position, but can extend more posteriorly or anteriorly and even extend into the biceps tendon. Sometimes an axillary view can be of help, but when in doubt go to CT.
Stabilizing mechanism in bone-grafting of a large glenoid defect. On MR-athrography the labrum is missing on the anterior glenoid and the labral fragment is displaced anteriorly arrow. This page was last edited on 27 Octoberat W B Saunders Co.
Biomechanics of the shoulder. Hill-Sachs lesion HSL in the mid-range: Imaging the joint in the Lexion position is helpful in increasing detection rates.

J Shoulder Elbow Surg ; The effect of a glenoid defect on anteroinferior stability of hombo shoulder after Bankart repair: If the HSL is out of the glenoid track off-track lesionthere is a risk of engagement and dislocation.
Mid-range stability is provided by the negative intra-articular pressure 34 and the concavity-compression effect. Treatment is surgical re-attachment of the labrum preferably via arthroscopy.

The structure anterior to the glenoid is not a thorn labrum, but the middle glenohumeral ligament. In Italian [ PubMed ].
Hill-Sachs lesion HSL and the glenoid: Bankart fracture This is a post-reduction view. Parke et al 35 evaluated engagement before and after the Bankart repair.

There is also a Hill-Sachs defect red arrow. Notice the very large fracture of the glenoid rim with displacement. First notice the Hill-Sachs defect indicating a prior anterior dislocation blue arrow.
