Hill Sachs lesion MRI

Magnetic resonance (MR) imaging has proved to be a valuable method for documenting Hill-Sachs lesions. The authors retrospectively analyzed the diagnostic interpretations at plain film radiography, arthroscopy, and MR imaging in 76 patients Hill-Sachs lesions were found in all of the patients on MRI and arthroscopy. For the engaging group, the mean measurements for the Hill-Sachs lesions were as follows: 2.15 ± 0.63 (SD) cm (anteroposterior) × 2.13 ± 0.54 cm (craniocaudal) × 0.69 ± 0.23 cm (depth); and 3.60 ± 2.83 cm 3 (volume) (Table 1) Abstract PURPOSE: To present a method of differentiating Hill-Sachs lesions from the anatomic groove in the posterolateral humeral head with use of magnetic resonance imaging

Hill-Sachs lesion: comparison of detection with MR imaging

Reverse Hill-Sachs lesion, also called a McLaughlin lesion, is defined as an impaction fracture of anteromedial aspect of the humeral head following posterior dislocation of the humerus. It is of surgical importance to identify this lesion and correct it to prevent avascular necrosis MRI confirms the findings seen on X-ray and CT of Hill-Sachs lesion with bony Bankart as sequelae to recurrent shoulder dislocation On these sagittal series, the anterior ligamentous structures are nicely demonstrated. The extent of the tear of the anteroinferior capsulolabral complex (Bankart lesion) is well shown. Bony impression on the posterior humeral head better known as Hill-Sachs lesion. SGHL: superior glenohumeral ligament

Definition/Description A Hill-Sachs lesion is a compression fracture or dent of the posterosuperolateral humeral head that occurs in association with anterior instability or dislocation of the glenohumeral joint. It was first described by two radiologists by the name HA Hill and MD Sachs in 1940 A Hill-Sachs lesion, or Hill-Sachs impaction fracture, is an injury to the back portion of the rounded top of your upper arm bone (humerus). This injury occurs when you dislocate your shoulder... The astute interpreter of MRI should determine whether a Hill-Sachs lesion is on- or off-track in all cases of anterior shoulder instability. Careful evaluation of this status as well as the extent of glenoid bone loss provides valuable guidance towards the operative approach The search terms were Hill-Sachs and measurement for the initial search and Hill-Sachs bone loss for the second, to be present in the keywords, abstracts and title. All articles that presented a method for quantifying measurement of Hill-Sachs lesions were analysed.Several methods are currently available to evaluate Hill-Sachs lesions Dr Mohamed Saber and Assoc Prof Frank Gaillard ◉ ◈ et al. Bankart lesions are injuries specifically at the anteroinferior aspect of the glenoid labral complex and represent a common complication of anterior shoulder dislocation. They are frequently seen in association with a Hill-Sachs lesion

Engaging Hill-Sachs Lesion: Is There an Association

Hill-Sachs lesion volume was measured on 33 patients using both the additive cross-sectional and triaxial measurements. The range in Hill-Sachs lesion volumes was 37-2309 mm3. Spearman Rank Correlation Coefficients for both observers using the same method (inter-observer reliability) and for th Posterior instability lesions include the reverse Bankart (Figure 5a), the posterior labrum periosteal sleeve avulsion injury (POLPSA) (Figure 6a), and the posterior band inferior glenohumeral ligament avulsion from the humerus (PHAGL) (Figure 7a). 7,8 The MRI findings in these patients often provide useful indicators of clinical significance al margin of the Hill-Sachs lesion. The Hill-Sachs interval was assessed in all three MRI planes (ax-ial, coronal, and sagittal). The measurement was made on the axial images at the point with the largest medial extent of the Hill-Sachs lesion. Lesions were considered engaging, or off-track, if the Hill-Sachs interval exceeded the glenoid trac With a Hill-Sachs lesion that occupies >30% of the humeral head surface, as established by CT or MRI scan, surgery is required due to the high instability of the shoulder

Bankart and Hill-Sachs lesions are often associated with anterior shoulder dislocation. The MRI technique is sensitive in diagnosing both injuries. The aim of this study was to investigate Bankart and Hill-Sachs lesions with MRI to determine the correlation in occurrence and defect sizes of these lesions At CT or MR imaging, a Hill-Sachs lesion should be differentiated from the normal groove that is found at the posterolateral humeral head but more inferiorly. All Hill-Sachs lesions occur within the superior 4-5 mm of the humeral head margin, which should otherwise be circular on axial CT or MR images A Hill-Sachs injury to the shoulder can occur due to a shoulder dislocation, resulting in a Hill-Sachs lesion or a Hill-Sachs deformity of the head of the humerus bone (the upper arm bone By determining whether a Hill-Sachs lesion is on-track or off-track, one can predict the likelihood that the lesion will engage in abduction, a status known to be highly correlated to recurrent instability. The astute interpreter of MRI should determine whether a Hill-Sachs lesion is on- or off-track in all cases of anterior shoulder instability A Hill-Sachs lesion can be detected on radiographic imaging, but computed tomography (CT) and magnetic resonance imaging (MRI) are more sensitive [4,5]. Traditionally, CT scans were obtained to assess humeral and glenoid bone loss

Hill-Sachs lesion and normal humeral groove: MR imaging

The 3D CT imaging is effective and reproducible in determining lesion size. Determination of Hill-Sachs interval width is also reliable when it is applied to the glenoid track concept. Measured values on 3D and 2-dimensional imaging using a conventional CT scanner may slightly underestimate true mea Hill-Sachs lesion with the glenoid, either without or with a corresponding bony gle-noid defect (bipolar bone loss). Hill-Sachs lesions that remain within the glenoid track are at lower risk for engagement and insta-bility. As our understanding of the clinical significance of bipolar bone loss continues to improve, 3D MRI is expected to play a Hill-Sachs lesions are a posterolateral humeral head compression fracture. This is demonstrated on both the radiograph and subsequent ultrasound scan Hill-Sachs imaging Radiography. Results are presented in (Table 6). Ito et al. positioned patients supine with the shoulder in 135 ° flexion and 15 ° of internal rotation to obtain a view of the posterolateral notch and calculate depth and width of the Hill-Sachs lesion but reliability was not explored

The vast majority of Hill-Sachs lesions are small or medium sized and can be ignored for management purposes. In larger symptomatic lesions associated to labrum or glenoid injuries, the preferred surgical approach usually encompass glenoid-based bone augmentation procedures. Direct treatment of the Hill-Sachs lesion is rarely required. 2.1.2 Signs & Symptoms of Hill-Sachs Lesion. The most common sign of Hill-Sachs lesion is severe pain in the shoulder, especially during movement. Other symptoms you may notice include: Nausea, lightheadedness and weakness.

Objective: Bankart and Hill-Sachs lesions are often associated with anterior shoulder dislocation. The MRI technique is sensitive in diagnosing both injuries. The aim of this study was to investigate Bankart and Hill-Sachs lesions with MRI to determine the correlation in occur-rence and defect sizes of these lesions A Hill-Sachs lesion is a severe shoulder injury that might require surgical repair. The shoulder joint is a combination of the head of the humerus and the socket called the glenoid. While the shoulder has an extensive range of motion, it is also easy to dislocate Although larger Hill-Sachs injuries may be visible on x-ray, MRI imaging is typically the most helpful method in diagnosing a Hill-Sachs lesion and determining its size. MRI may also be used to rule out a labral tear (patients < 40 years old) or rotator cuff tear (patient > 40 years old) with shoulder dislocation or instability 26 Hill-Sachs Lesion on MR Arthrography of the Shoulder: Relationship with Bankart Lesion on Arthroscopy and Frequency of Shoulder Dislocations Ji Na Kim1, 2, Min Hee Lee1, 3, Joong Mo Ahn4 1Department of Radiology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, Seoul, Korea 2Department of Radiology, Chungnam National University Hospital, Daejeon, Kore

  6. Di Giacomo et al. [] in 2014 introduced an imaging-based technique called the on-track off-track method, which entails use of CT with 3D reconstructions to evaluate Hill-Sachs lesions and glenoid bone loss simultaneously.Based on the width of the Hill-Sachs lesion and size of the glenoid track, this technique is believed to improve the ability to predict engagement preoperatively and thus lead.
  7. Humeral bone loss. The rate of Hill-Sachs lesions in recurrent anterior shoulder instability has been reported to be as high as 93% and increased attention has been given to the size and location of humeral bone loss.However, because of its 3-dimensional shape (e.g., location, width, length, depth), the accurate and reproducible characterization of Hill-Sachs lesion has been more complex

If a Hill-Sachs lesion affects only a small area of the humeral head (<20%) you may not require treatment other than physical therapy to strengthen muscles that support your shoulder joint, such as the rotator cuff and muscles that stabilize the scapula. Larger lesions can cause instability of the joint and may require surgery

A Hill-Sachs injury occurs only when there is a forward dislocation of the shoulder. Hill Sachs Lesion is named after two American radiologists Harold Hill and Maurice Sachs - who in 1940, popularized the injury, provided radiographic evidence and determined a link between the lesion and recurrent instability 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 Hill-Sachs lesion. Hill-Sachs lesion (Figure (Figure8) 8) is the most common injury associated with anterior glenohumeral instability. It consists of bony injury of the posterosuperior humeral head manifesting as cortical bony loss, impaction fracture or associated bone marrow edema in acute cases In contrast, Hill-Sachs compression lesions are located on the articular surface of the posterior humeral head and are particularly associated with anterior shoulder dislocations. 7 The Hill-Sachs lesion is created when the relatively soft posterosuperior humeral head impacts the harder bone of the anterior glenoid rim

Hill-Sachs lesion. is a compression fracture of the posterolateral humeral head due to its compression against the anteroinferior part of the glenoid when the humerus is anteriorly dislocated. the anatomical apposition gives a characteristic position of the lesion; the comparable injury caused by posterior dislocation is a reverse Hill-Sachs. A Hill-Sachs lesion is a bony defect of the humeral head that is often linked with recurrent anterior shoulder instability. In fact, it has been proven that the Hill-Sachs lesion is quite common and is demonstrated in 67-93% of anterior dislocations and can reach an incidence rate of 100% in patients with recurrent anterior shoulder instability [1,2,3,4]

The Hill-Sachs lesion that extended medially over the glenoid track was observed in 7% of 100 shoulders with recurrent anterior instability. There were 2 types of Hill-Sachs lesions: a wide and large Hill-Sachs lesion and a narrow but medially located lesion. 7% JSES, 2013 Cincinnati Sports Medicine Instability Severity Index Score Balg, Boileau Hill-Sachs Lesion. Hill-Sachs lesion = a dent in the back of the humeral head which occurs during the dislocation as the humeral head impacts against the front of the glenoid. Described in 1940 by two American radiologists, Harold Arthur Hill (1901-1973) and Maurice David Sachs (1909-1987) Large humeral head Hill-Sachs lesions may cause engagement of the defect with the anterior labrum even after anterior glenoid reconstruction and, therefore, are indication for surgical repair . The prevalence of engaging Hill-Sachs lesion is about 7% . Typically, an engaging Hill-Sachs has an oblique long axis in neutral shoulder position that. develop Bankhart and Hill-Sachs lesions [3, 4]. The classic Bankart lesion is an anterior labral tear/detachment which extends through periosteum, and may involve the bony glenoid or just the labrum. The classic Hill-Sachs lesion is an impaction injury of the posterolateral humeral head, caused by contact of the Imagin

Bankart lesion. A Bankart lesion is an avulsion of the anteroinferior glenoid labrum that is primarily caused by anterior dislocation of the shoulder joint. This is a diagnosis that is made with MRI or joint arthroscopy. Hill-Sachs defec Further evaluation was done with magnetic resonance imaging (MRI) (Figure 3) and computed tomography (CT) scan (after surgery) (Figure 4). We noted Hill-Sachs lesion on posterior-lateral surface of humeral head, reverse Hill-Sachs lesion on anterio-medial surface, and a fracture line connecting these lesions (Figure 4 )
