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.

There is a Bankart lesion with extension into the cartilage, i. With the arm moving along the posterior end-range of movement, or with the arm in various degrees of abduction, maximum external rotation and maximum horizontal extension, the glenoid moves along the posterior articular swchs of the humeral head. Motion in a posterior direction is limited by the posterior rim of the glenoid which is in an anteverted position.
Humeral Bankwrt Reconstruction Bone augmentation of the humeral head has hilk shown to successfully manage large Hill-Sachs lesions with or without concomitant glenoid bone loss Fig. Posterior dislocations are uncommon and easily missed, because there is less displacement compared to the anterior dislocation. Skeletal Radiol ; 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.
Even with specialized forms of radiographs, it still stands that CT and MRI are superior forms of imaging for a Hill-Sachs defect [ 21 ]. At each side of the sacrum, the ala structures articulate with the ilium bones forming the sacro-iliac joints. df
Hill Sachs Lesion – Physiopedia
Injuries of shoulder and upper arm Musculoskeletal disorders Orthopedic problems Lesion. This circle is considered to be close to the original shape of the glenoid.
Wolf EM, Arianjam A. Fractures of the coccyx involve the tailbone, the terminal portion of the spine situated below the sacrum formed by 3 to 5 fused vertebrae. Since the socket glenoid covers only one-quarter of the surface of the ball humeral head1 it has the greatest range of movement of all the joints in the body.
‘On-track’ and ‘off-track’ shoulder lesions
Surgery for a Bankart lesion is highly recommended for active athletes, even after a single dislocation, especially those involved in contact sports, which increase the likelihood of a second shoulder dislocation and shoulder joint injury. Recurrent anterior shoulder instability: Large, engaging Hill-Sachs fractures can contribute to shoulder instability and will often cause painful clicking, catching, or popping.
Support Radiopaedia and see fewer ads. Remplissage The remplissage technique has become a popular method in managing Hill-Sachs lesions. Recent Findings 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. From Wikipedia, the free encyclopedia. Read it at Google Books – Find it at Amazon.
Hill-Sachs lesions may be difficult to appreciate on x-rays, frequently requiring CT or MRI for full characterisation. Sometimes this makes it easier to understand the anatomy. This includes individuals actively playing contact sports football, rugby, hockey and throwing activity tennis, baseball, cricket. Treating the glenoid defects is often the solution to the glenohumeral instability.
Therefore, this is a stable shoulder; b the HSL is the same size as in abut it is not entirely covered by the glenoid due to a bony defect of the glenoid. However, it is essential to address the Hill-Sachs defect in the setting of an engaging lesion as multiple studies have come out demonstrating the increased recurrence rates of shoulder instability after arthroscopic repair when the Hill-Sachs lesion is not addressed at the time of surgery [ 6121734 ].
In a different study, Metzger and his colleagues [ 41 ] found that only 15 out of Grading of Hill-Sachs Defining a Bqnkart lesion is a multi-dimensional process because of the requirement for the examination of multiple different factors, such as size and orientation.
The major advantage of this new method hipl it avoids the need to go into the subacromial space to retrieve or tie sutures.
The Radiology Assistant : Shoulder MR – Instability
Surgical Management Surgical management hull a Hill-Sachs lesion is determined based off clinical evaluation and symptoms of instability. The anterior labrum is absent at the o ‘clock position Baankart is a Buford complex, which is a normal variant. Assessment of the glenoid defect There are various methods of assessing the bony defect of the bbankart, such as radiography, 15 – 17 CT, 18 3D CT, 19 MRI 20 and arthroscopy. Location of the Hill-Sachs lesion in shoulders with recurrent anterior dislocation.
Now, it has been shown in the literature that both open and arthroscopic surgeries are viable options with similar outcomes and failure rates [ 34 ].
The sacrum is a triangular-shaped bone formed by 5 fused vertebrae, which provide a posterior wall to the pelvic ring. Thank you for updating your details. Sagittal MR-arthrogram demonstrates the superior extension of the Bankart tear. Vankart in younger patients this results in a Bankart fracture or a Bankart lesion which is a tear of the anteroinferior labrum.
Dislocations of the shoulder with special reference to accompanying small fractures. Clockwise approach to labral pathology A Clockwise approach to the labrum is the easiest way to diagnose labral tears and to differentiate them from normal labral variants. When assessing the soft tissue anatomy of patients with glenohumeral instability, MRI has become the superior method [ 28 ].
As soon as the leeion contraction occurs with the arm elevated, the contraction force by the shoulder muscles pulls the humeral head against the glenoid socket, which in turn creates a resistance force against translation of the humeral head. Surgery is necessary in case of associated neurological symptoms.
