What does a positive sulcus test mean?
The presence of a sulcus is considered a positive test result and may indicate inferior instability or inferior glenohumeral ligament laxity.
How do you test for subluxation?
During physical examinations, subluxation is detected by palpation of the glenohumeral joint. The extent of shoulder subluxation can be quantified by the distance from the acromion to the humeral head, using fingerbreadth, caliper, or tape.
What is a deep sulcus?
In radiology, the deep sulcus sign on a supine chest radiograph is an indirect indicator of a pneumothorax. In a supine film, it appears as a deep, lucent, ipsilateral costophrenic angle within the nondependent portions of the pleural space as opposed to the apex (of the lung) when the patient is upright.
What does a sulcus sign indicate?
The Sulcus sign is an orthopedic evaluation test for glenohumeral instability of the shoulder. With the arm straight and relaxed to the side of the patient, the elbow is grasped and traction is applied in an inferior direction. With excessive inferior translation, a depression occurs just below the acromion.
What is deep sulcus sign?
The deep sulcus sign is a radiolucent lateral sulcus where the chest wall meets the diaphragm. In a supine film, it may be the only indication of a pneumothorax because air collects anteriorly and basally within the nondependent portions of the pleural space, as opposed to the apex when the patient is upright.
What is Dugas test?
[ dōō-gäz′ ] n. A test performed to determine whether an injured shoulder is due to a dislocation or a fracture. If the elbow cannot be made to touch the chest while the hand rests on the opposite shoulder, the injury is a dislocation.
What is Costophrenic sulcus?
the recess between the ribs and the lateral-most portion of the diaphragm, partially occupied by the most caudal part of the lung; seen on radiographs as the costophrenic angle.
How do you fix Hill-Sachs?
For smaller sized Hills-Sachs lesions, in which less than 20% of the humeral head has been affected, physical therapy, or careful observation may be an effective option. For more severe cases and larger lesions, surgery is likely your best option for healing.
What is the sulcus?
Definition of sulcus : furrow, groove especially : a shallow furrow on the surface of the brain separating adjacent convolutions.
What is a brain sulcus?
A sulcus (plural: sulci) is another name for a groove in the cerebral cortex. Each gyrus is surrounded by sulci and together, the gyri and sulci help to increase the surface area of the cerebral cortex and form brain divisions.
What is the sulcus sign in lungs?
The deep sulcus sign describes a deep and lucent costophrenic angle that extends more inferiorly than usual. In the supine position, intrapleural air accumulates from the anteromedial region to the laterocaudal region as the pneumothorax increases.
