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.

Shoulder MR – Instability

Due to the ABER-position the anterior band of the inferior Banlart creates tension on the anteroinferior labrum and contrast fills the tear. The purpose of this study is to provide an update to the orthopedic field in regard to treatment of the Hill-Sachs lesion and anterior shoulder instability.

Sometimes an axillary view can be of help, but when in doubt go to CT.

The arrow points to the medially displaced labroligamentous complex. Mid-range stability is provided by the negative intra-articular pressure 34 and the concavity-compression effect. On coronal images you want to make sure whether this is a variant like a labral recess or labral foramen or whether this is a SLAP.

In our daily practice, we use en face views of both glenoids and the posterior view of the involved humeral head on 3D CT. Fractures of the coccyx involve the tailbone, the terminal portion of the spine situated below the sacrum formed by 3 to 5 fused vertebrae. Hill-Sachs lesion HSL entirely covered by the glenoid at the sxchs Ramhamadany and Modi noted that an isolated Hill-Sachs lesion increases the chances of a bipolar defect by a factor of 2.

CT scan showing a bony Bankart lesion at the antero-inferior glenoid. The coronal images shows the medially displaced labrum red arrow.

However, this procedure is uncommon given the variability in the derotation achieved and its reportedly high complication rate [ 76 ]. Hill-Sachs lesion classification under arthroscopic findings. In the literature, there has been debate as to whether the remplissage procedure leads to loss in range of motion and stiffness, but it is becoming clearer that there is a correlation between loss of internal-external range of motion and the remplissage. J Shoulder Elbow Surg. Scroll through the images.

The lower angle caused from the arm being in adduction resulted in the lesion passing diagonally in a non-parallel fashion across the anterior glenoid, which led to a lower extent of engagement and shoulder instability. Papers of particular interest, published recently, have been highlighted as: On MR-athrography the labrum is missing on the anterior glenoid and the labral fragment is displaced anteriorly arrow.

This study has important implications because it would be beneficial to use 3D-MR in place of CT due to its ability to image without radiation; additionally, patients would only need to get one scan with the MRI instead of obtaining both MRI and CT for preoperative evaluation.

Bankart lesion

sacs Summary Osseous defects in the glenohumeral joint are issues that can cause severe shoulder instability with high risk of recurrent dislocations. Hill-Sachs lesions are unavoidable when talking about anterior shoulder instability because of their high prevalence in patients with recurrent instability. In German [ PubMed ].

Quantification of a glenoid defect with three-dimensional computed tomography and safhs resonance imaging: However, depending on concomitant glenoid bone loss and the degree of engagement with the glenoid, even a small Hill-Sachs lesion can become clinically significant [ 5 ]. There are two types of glenoid bone loss: Stabilizing mechanism in bone-grafting of a large glenoid defect. However, multiple authors since then have documented the ability of the implants to be used in cases of anterior shoulder instability [ 6970 ].

Bankart lesion Bankart lesions are labral tears without an osseus fragment. They defined the orientation of an engaging Hill-Sachs lesion to be parallel to the glenoid so the lesion will make contact with the corner of the glenoid. Postoperative imaging showing osteochondral allograft union into the Hill-Sachs lesion. National Center for Biotechnology InformationU. This is probably the result of a very large long-standing rotator cuff tear with progressive cranialisation of the humeral head and erosion of the acromion.

In this technique, they used a bone tamp to carefully raise the cortical surface of the humerus in small increments. Surgical management of a Hill-Sachs lesion is determined based off clinical evaluation and symptoms of instability.

Recurrent anterior shoulder instability: Quadrilateral space syndrome caused by a humeral osteochondroma: The stabilizing mechanism of the Latarjet procedure: Head and neck Dislocation of jaw Whiplash. On the AP-view the head looks strange due to the internal rotation. Am J Sports Med. CT-images in another patient show a reversed osseus Bankart in a patient with posterior dislocation.

Posterior pillar often associated with dislocation of the hip including the bsnkart bearing part of joint. The most recent literature covering the Hill-Sachs lesion has focused on the relatively new and unexplored topic of the importance of concomitant injuries while treating a humeral head defect.

Bankart lesion – Wikipedia

Articles Cases Courses Quiz. In general, the negative value of the intra-articular pressure increases linearly with an increase of downward pull. This resulted in both a Hill-Sachs impression fracture on the posterior aspect of the humeral head blue arrow and an impression fracture on the anterior aspect as a result of posterior dislocation red arrow.

Shibayama and Iwaso found that an engaging Hill-Sachs lesion is highly susceptible to recurrence if treated with a typical arthroscopic capsuloligamentous repair bankwrt no attention to the osseous defect [ 6 ].

The abrupt displacement of the humerus causes the cartilage covering the humerus head to hit the glenoid. A grading system is used based on the amount of bone loss or severity of the humeral head deformity.

There are several different treatment options to address anterior shoulder instability, both open procedures and arthroscopic techniques [ 101744 ]. It is often associated with a Bankart lesion of the glenoid. Radiograph showing a bony Bankart lesion with stationary fragment at the inferior glenoid.

When refering to evidence in academic writing, you should always try to reference the primary original source.
