When the damage only involves the labrum it is called a Bankart lesion. A Hill- Sachs lesion occurs when the lesion to the labrum presents simultaneously with a. There are two types of labral tears: SLAP tears and Bankart lesions. On MR a Hill-Sachs defect is seen at or above the level of the coracoid. Horst and his colleagues also found that a larger Hill-Sachs lesion leads to greater . Burkhart and de Beer first described the concept of engaging vs. . Bankart repair and remplissage for a large engaging Hill-Sachs lesion.

In other projects Wikimedia Commons. Summary Osseous defects in the glenohumeral joint are issues that can cause severe shoulder instability with high risk of recurrent dislocations. A Bankart lesion consists of a tear of the glenoid labrum. The labrum of the shoulder joint can be torn as a consequence of a forceful shoulder bankagt.
The Radiology Assistant : Shoulder MR – Instability
We apply this width 0. Kumar VP, Balasubramaniam P. However, with the progress of knowledge about the glenoid track concept and engagement, the diagnosis and preoperative decisions are becoming more accurate.
J Shoulder Elb Surg. Remplissage, humeral hikl grafts, weber osteotomy, and shoulder arthroplasty for the management of humeral bone defects in shoulder instability: The anterior and posterior drawer tests load and shift test and sulcus test are performed with the arm in the mid-range of movement because these tests are aimed to detect the laxity of the shoulder joint.
Hill-Sachs lesion | Radiology Reference Article |
No-one can tell precisely what one-third of the glenoid is. In the ABER position however there is tension on the antero-inferior labrum by the stretched anterior band of the inferior glenohumeral ligament and you have more chance to detect the tear.
It causes damage to different tissues surrounding the glenohumeral jointsuch as ligaments, rotator cuff tendons, joint banart as well as the bone and cartilage of the humeral head.
Perthes lesion A Perthes lesion is a labroligamentous avulsion like a Bankart, but with a medially stripped intact periosteum.
Hill-Sachs is a posterolateral depression of the humeral head. It also details the relevant clinical and surgical findings that have been made throughout the literature in the past couple of years. Excellent side-to-side leison in glenoid size and shape.
In the recent vankart, there have been a multitude of studies progressing our knowledge over diagnosis and treatment concerning shoulder instability. Musculoskeletal imaging, the requisites. It is above or at the level of the coracoid in the first 18 mm of the proximal humeral head.
Posterior dislocation Posterior dislocations are uncommon and easily missed, because there is less displacement compared to the anterior dislocation. An additional study by Giles et al. Sometimes an axillary view can be of help, but when in doubt go to CT.
‘On-track’ and ‘off-track’ shoulder lesions
Anterior dislocation The shoulder almost always dislocates to anterior and inferior, because motion to superior is limited by the acromion, coracoid process and rotator cuff figure. Also, it has been bajkart that when the arm is in a position of abduction during the primary injury, there is a higher risk of engagement and subsequent dislocation. Correlation between Bankart and Hill-Sachs lesions in anterior shoulder dislocation.
Unable to process the form. Introduction A Hill-Sachs lesion is a bony defect of the humeral head that is often linked with recurrent anterior shoulder instability.
At each side of the sacrum, the ala structures articulate with the ilium bones forming the sacro-iliac hikl. They relate to the mechanisms of injury and bone fracture characteristics and provide a guideline towards suitable treatments.
Case 14 Case If a shoulder dislocation is produced by high-energy trauma, it can additionally impact on the humeral head.

No benefits in any form have been received or will be received from a commercial party related directly or indirectly to the subject of this article. Specific functional tests employed include the apprehension test, relocation test and sulcus sign. Sometimes the displacement is difficult to appreciate, especially when the transscapular-Y view is slightly rotated.
