MRI of shoulder after dislocation with Hill-Sachs lesion and labral Bankart's lesion. In young adults engaged in highly demanding activities shoulder surgery may be considered. [25] Arthroscopic surgery techniques may be used to repair the glenoidal labrum, capsular ligaments, biceps long head anchor or SLAP lesion or to tighten the shoulder ...
The light bulb sign is best observed on an AP radiograph of the shoulder. [5] Key features include: Rounded humeral head: The humeral head appears symmetrically rounded, resembling a light bulb due to internal rotation. Loss of normal glenohumeral overlap: The humeral head is posteriorly displaced, disrupting the alignment with the glenoid cavity.
Both before and after reduction, with lesions labeled. Vector (.svg) version is available. The bony Bankart lesion is new, as evidenced by lack of cortex on the superior part of the fragment, and is presumed to be caused by glenohumeral ligaments pulling the humerus towards the glenoid as the shoulder dislocates, causing a fracture even without significant external forces.
The Cunningham technique was originally published in 2003 and is an anatomically based method of shoulder reduction that utilizes positioning (analgesic position), voluntary scapular retraction, and bicipital massage. [7] If performed correctly most patients do not require analgesia for the performance of this technique.
The standard x-ray views of the shoulder include a true anterior-posterior view, a lateral (Y or outlet) view, and an axillary view. [13] A Velpeau view can be done as an alternative to the axillary view if an examinee is unable to position the shoulder for an appropriate image.
The Latarjet procedure involves the removal and transfer of a section of the coracoid process and its attached muscles to the front of the glenoid. This placement of the coracoid acts as a bone block which, combined with the transferred muscles acting as a strut, prevents further dislocation of the joint. [ 3 ]
X-ray at right shows same shoulder after reduction and internal rotation, revealing both a Bankart lesion and a Hill-Sachs lesion. Diagnosis can be suspected by history and physical examination which is usually followed by imaging. Because of the mechanism of injury, apprehension of anterior dislocation is common with provocative maneuvers.
Surgical positioning is the practice of placing a patient in a particular physical position during surgery. The goal in selecting and adjusting a particular surgical position is to maintain the patient's safety while allowing access to the surgical site. Often a patient must be placed in an unnatural position to gain access to the surgical site ...
