Elevate your elbow above the level of your heart as often as you can. This will help decrease swelling and pain. Prop your elbow on pillows or blankets to keep it elevated comfortably. While your elbow is elevated wiggle your fingers and open and close them to prevent hand stiffness.
An posterior fat pad is always pathologic. In adults this indi es intraarticular trauma. Figure 3 Lateral xray of the elbow demonstrating a significant anterior fat pad red arrows and a posterior fat pad blue arrows . Case courtesy of Dr. Ian Bickle Radiopaedia.org
Positive fat pad sign Distention of the joint will cause the anterior fat pad to become elevated and the posterior fat pad to become visible. An elevated anterior lucency or a visible posterior lucency on a true lateral radiograph of an elbow flexed at 90 is described as a positive fat pad sign figure .
The elbows synovial joint capsule has a volume of approximately 2530 cc Fat pads Synovial joint is surrounded by a deposit of fat within the coronoid and olecranon fossae Anterior fat pad Small and normall visible on a lateral XRay
2. FAT PADS The anterior fat pad is normal. What is NOT normal is if you see it bulging out in what we call the sail sign. This is an abnormal effusion of the joint that indi es a fracture is present even if you cant see it You should NEVER be able to see a POSTERIOR FAT pad. If you can see one this is automatically abnormal and indi es a fracture.

Replace the elbow xray as initial screen especially in kids. One pediatric study showed utility in using POCUS assessment of hemarthrosis/posterior fat pad as a FAST exam for the traumatized elbow to rule out elbow fractures without radiation. Rule out open fracture. We had another patient with a very similar story several days later.
Exposure factors must ensure that the anterior and supinator fat pads are shown in contrast with the surrounding soft tissue the posterior fat pad will only be demonstrated if there is bony injury The importance of optimum exposure factor selection cannot be emphasised enough especially in the case of the elbow radiograph requested after trauma.
visible posterior fat pad always indi es an elbow effusion visible anterior fat pad may be seen in normal patients and should only be thought of as an indi or of an elbow effusion when massively raised if there is an effusion in a pediatric patient think supracondylar fracture or intraarticular fracture e.g. lateral condyle fracture

the olecranon process can be seen in profile. the elbow fat pads are the least compresed. It must be realized that in partial or complete extension the olecranon process elevates the posterior elbow fat pad and simulates joint pathology. Image Receptor 8 x 10 inches single or 24 x 30 cm divided.
additional imaging. The anterior fat pad displacement ranged from 5 to 15 mm mean 9.25 and the posterior fat pad was elevated from 1 to 6 mm mean 3.2 . CONCLUSION Our data using MR imaging suggests that fat pad elevation in the presence of recent trauma is frequently associated with a fracture. The size of

Anterior Fat Pad Radiographically the anterior fat pad is a superimposition of the radial and coronoid fat pads when viewing a lateral radiograph. Their lo ion is anterior to the coronoid and radial fossae lo ed on the distal anterior humerus. These fat pads are slightly more radiolucent than the adjacent muscle tissues making them
The sail sign on an elbow radiograph describes the elevation of the anterior fat pad to create a silhouette similar to a billowing spinnaker sail from a boat. It indi es the presence of an elbow joint effusion. The anterior fat pad is usually concealed within the coronoid fossa or seen paralleling the anterior humeral line.
A fat pad sign is when the normal pad of fat that sits around the bones in the elbow becomes raised up. This is usually due to swelling in that part of the elbow. This can be caused by damage to the ligaments in the elbow or sometimes by a small fracture break to one of the elbow bones that cant be seen on an Xray. The reason it cant ...
AP and lateral Xray views of the elbow are usually sufficient. Findings may be quite subtle and the only clue may be the fat pad sign triangular radiolucent shadows anterior and posterior to the distal humerus on lateral Xray indi ing haemarthrosis and displacement of intraarticular fat pad often associated with intraarticular skeletal injury .
Standard xrays of the elbow include an anteroposterior view with the elbow extended and a true lateral view with the elbow flexed to 90 and the forearm neutral. The fat pads are best visualized in the lateral view. In a positive anterior fatpad sign the fat pad is displaced ventrally and superiorly changing the inferior margin from
Fat pads. A small anterior fat pad may be normal. An abnormal anterior fat pad quotsailquot is caused by blood or inflammatory fluid within the joint space. In trauma a positive fat pad sign intraarticular fracture. Posterior fat pad is always abnormal. In trauma any visible posterior fat pad intraarticular fracture
FAT PADS The anterior fat pad is normal. What is NOT normal is if you see it bulging out in what we call the sail sign. This is an abnormal effusion of the joint that indi es a fracture is present even if you cant see it

The appli ion of the elbow fat pad signs in diagnosis should be restricted to nonrotated radiographs performed with the elbow flexed. In the case of elbow joint effusion or hemarthrosis the anterior fat pad is elevated and sickleshaped whereas the posterior fat pad becomes visible as it is pushed from its fossa by fluid expanding the ...
Xray can also appear normal Figures 25 Xray of elbow of 44 yo with posterior impingement of elbow and olecranon process osteophytosis AP lateral oblique olecranon oblique radial CT Will provide greater sensitivity than Xray when looking for loose bodies or osteophytosis leading to posterior impingement.
Fat Pad Sign As noted previously extrasynovial fatty collections are present within the capsular margins of the elbow joint. The posterior fat pad normally lies deep within the olecranon fossa.

The anterior fat pad is a summation of the radial and coronoid fat pads which are normally pressed into the shallow radial and coronoid fossae by the brachialis muscle during extension. The posterior fat pad is normally pressed into the deep olecranon fossa by the triceps brachii tendon and anconeus muscle during flexion and the third lies over the supinator as it wraps over the radius.
The reason is that growth plate fractures may not show up on an Xray like normal broken bones. Therefore your doctor may request an Xray of the opposite elbow your child 39s uninjured side to compare the two for differences. Often the only sign of a broken elbow in a child is swelling seen on Xray the socalled 39fatpad sign 39 .
On the lateral view of the normal elbow Figures 33 A and C without a joint effusion the posterior fat pad is not apparent while the anterior fat pad is visible but not elevated. In the presence of a joint effusion hemarthrosis the fat pads are displaced and both the anterior and posterior fat pads become visible Figures 33 B and D .
Figure 14.8B Lateral xray of the elbow displaying a humeral fracture. The anterior humeral line has been drawn on the image. Imaging Assessment. Findings There was a displaced fracture of the distal humerus with ventral displacement of the anterior fat pad consistent with a joint effusion. Interpretation Supracondylar humeral fracture.
Presence and elevation of the anterior and posterior fat pads on the lateral elbow xray. Interpretation Visible anterior fat pad radiolucency anterior to the distal humerus normally visible Visible posterior fat pad radiolucency posterior to the olecranon normally hidden behind olecranon and thus presence indi es effusion Occult fracture Sail sign raised anterior fat pad due to effusion Occult fracture usually of radial head
Fat pads The elbow joint has anterior and posterior fat pads which are extrasynovial but within the articular capsule. These are present as a radiolucent black line compared to bone and surrounding soft tissues in lateral Xrays. Normal finding Straight radiolucent line immediately anterior to the distal humerus anterior fat pad .
