What is a Zanca view of the shoulder?
The Zanca view is a specialized projection of the acromioclavicular joint (ACJ), which will better demonstrate the acromioclavicular joint free from superimposition and aid in the assessment of distal osteophytes.
What is the Zanca view xray?
Zanca view radiograph of acromioclavicular joint. The radiograph of the acromioclavicular joint using the Zanca view (bottom image) provides a clearer view of the joint, without overlapping bone, compared to a standard AP view of the shoulder (top image).
Why do we see Zanca?
The Zanca view is used in the assessment of acute and chronic acromioclavicular joint injuries. The view optimizes visualization of the acromioclavicular joint, as overlying structures can limit assessment in an AP projection, with distal osteophytes better visualized.
What is an Alexander view?
… 22,27 The Alexander view, 1 a lateral stress radiograph taken with the hand of the arm being imaged placed in the contralateral axilla, facilitates evaluation of horizontal and vertical displacement on a single view.
Will an xray show AC joint injury?
The acromioclavicular joint can be assessed with standard shoulder X-rays. Loss of alignment of the inferior surfaces of the clavicle and acromion indicates disruption of the acromioclavicular ligaments at the acromioclavicular joint (ACJ).
How do you diagnose an AC joint injury?
Symptoms of an AC joint injury
- Shoulder or arm pain.
- A visible bump, bruise, or swelling on your shoulder.
- Limited shoulder mobility.
- Weakness in your shoulder or arm.
- Pain when lying on the affected side.
- A popping sound when you move your shoulder.
What is the Pearson method in radiography?
In the Pearson method (AP projection) the CR is perpendicular to the midpoint between the AC joints for a single projection, and is directed at each respective AC joint when two separate exposures are needed for each shoulder in broad-shouldered patients.
How do you diagnose AC joint sprain?
How to diagnose an AC Joint sprain – YouTube
What are 3 special tests for the shoulder?

- Adsons Test.
- Anterior Drawer Test Of The Shoulder.
- Apprehension Test.

Can an AC joint heal without surgery?
Most people do well without surgery. The severe injury (Grade 3) can be treated either nonoperatively or operatively. Non-operative treatment involves immobilisation in a sling for two to three weeks followed by a course of physiotherapy.
What is a Grashey view?
The shoulder AP glenoid view also known as a true AP or a ‘Grashey view’ is an additional projection to the two view shoulder series. The projection is used to assess the integrity of the glenohumeral joint.
How much weight is used for AC joint xray?
After the first exposure in AP Acromioclavicular joints is made without weights and the cassette(s) has (have) been changed, for large adult patients, strap 8 to 10 pounds minimum weights to each wrist, and, with shoulders relaxed, gently allow weights to hang from wrist while pulling down on each arm and shoulder.
What is a positive scarf test?
This test is considered positive if the maneuver successfully reproduces the patient’s symptoms of pain localized over the AC joint. A positive test is usually suggestive of AC joint osteoarthritis or a ligamentous injury to the AC joint (i.e., ligament sprain or joint separation).
What is a positive Hawkins test in the shoulder?
The Hawkins Kennedy test is used to assess shoulder impingement. In this test the clinician stabilizes the shoulder with one hand and, with the patient’s elbow flexed at 90 degrees, internally rotates the shoulder using the other hand. Shoulder pain elicited by internal rotation represents a positive test.
How serious is an AC joint injury?
Leaving your AC joint injury untreated means your condition can worsen, which can have serious consequences, such as: Severe shoulder separation. Serious displacement or collarbone fracture. Arthritis in your shoulder.
Is AC joint Same as rotator cuff?
The rotator cuff covers the head of the upper arm bone and attaches it to the shoulder blade. The AC (acromioclavicular) joint is formed where a portion of the scapula (acromion) and the clavicle meet and are held together by tough tissues (ligaments) that act like tethers to keep the bones in place.
How do you take Grashey view?
The AP oblique Grashey view is obtained with the patient rotated 35-45 degrees and his or her back (scapular body) up against the imaging detector.
How do you get Grashey view?
What does a positive AC joint instability test mean?
A positive test is usually suggestive of AC joint osteoarthritis or a ligamentous injury to the AC joint (i.e., ligament sprain or joint separation).
What is positive Hawkins Kennedy test?
A positive Hawkins-Kennedy test is indicative of an impingement of all structures that are located between the greater tubercle of the humerus and the coracohumeral ligament. The impinged structures include the supraspinatus muscle, teres minor muscle, and the infraspinatus muscle.
What are the 2 tests for shoulder impingement?
The two most popular special tests for shoulder impingement are the Neer test and the Hawkins test. In the Neer test, the examiner stabilizes the scapula while passively elevating the shoulder, in effect impinging the humeral head into the acromion.
What is the fastest way to heal an AC joint?
Treatment for AC joint sprain
- Rest. This allows your shoulder to heal.
- Sling. This protects the shoulder and holds the joint in a good position for healing.
- Cold packs. These help reduce swelling and relieve pain.
- Prescription or over-the-counter pain medicines.
- Arm and shoulder exercises.
What is the recovery time for AC joint surgery?
Time, rest and gradual rehabilitation typically result in a shoulder free of pain and functional limitations. The recovery time varies from patient to patient, but full recovery typically occurs within 6-12 weeks. A return to contact sports may require more recovery time to reduce the risk of re-injury.
What does a Grashey view show?
How do you do velpeau view?
Patient position
- the patient is erect (or sitting) facing away from the table.
- the image receptor is placed on the table behind the patient beneath the shoulder.
- patient leans 30° backward toward the table (allowing for an axial view of the shoulder)
