Elbow Injuries and Fractures | CE Article | NursingCenter A lateral elbow radiograph with no elbow fracture identified yet abnormal fat pads on the lateral film indicates an occult elbow fracture . The lack of an abnormal fat pad does not exclude an elbow fracture. Any fluid accumulation in the elbow joint can result in a positive fat pad such as septic arthritis and gout.
Occult fracture | Radiology Reference Article | Radiopaedia.org There may be clinical signs of a fracture without one actually being seen. MRI or nuclear medicine studies are sometimes required to make the diagnosis. Technically any fracture may be occult but classic examples include: distal radius fracture (pronator quadratus fat pad sign may be positive) neck of femur fracture

Point-of-Care Ultrasound: Sonographic Posterior Fat Pad Sign . Diagnosis of elbow fracture can sometimes be difficult with plain radiography due to overlapping bones growth plates and maturing bones in the pediatric population. The radiographic posterior fat pad (PFP) sign is one of the frequently referenced indirect signs of an occult elbow fracture.
Imaging of Elbow Fractures and Dislocations in Adults . Elbow fractures and dislocations. Elbow effusion with associated fat-pad elevation in the setting of radial head fracture. The anterior fat pad is elevated and its undersurface is convex giving the "spinnaker sail sign." The posterior fat pad is elevated out of the deep olecranon fossa and is visible just above the cortex of the distal humerus.
The Posterior Fat Pad Sign in Association With Occult . Conclusions: This prospective study demonstrated that the posterior fat pad sign was predictive of an occult fracture of the elbow following trauma in thirty-four (76 percent) of forty-five children who had no other evidence of fracture on anteroposterior lateral and oblique radiographs after the injury. This finding is in contrast to those .
The Radiology Assistant : Fractures in Children Positive fat pad sign (2) Any elbow joint distention either hemorrhagic inflammatory or traumatic gives rise to a positive fat pad sign. If a positive fat pad sign is not present in a child significant intra-articular injury is unlikely. A visible fat pad sign without the demonstration of a fracture should be regarded as an occult fracture.
Distal Humeral Fractures - Injuries; Poisoning - MSD Manual . However if a posterior fat pad is seen or if a large anterior fat pad (sail sign) is present an occult fracture should be assumed and should be treated as such. The anterior humeral line is a line drawn along the anterior border of the humerus on a true lateral x-ray.
A positive fat-pad sign reflects a response to an intra . A positive fat-pad sign reflects a response to an intra-articular disease process--such as occult fracture of the olecranon radial head or coronoid process. Other causes of the fat-pad sign include intra-articular blood from
Posterior Fat Pad Sign as an Indicator of Occult Elbow Fracture The posterior fat pad sign in association with occult fracture of the elbow in children. J Bone Joint Surg Am 1999;81:1429-1433. Consecutive pediatric subjects were prospectively enrolled in this study if they had an elevated posterior fat pad noted on initial radiographic evaluation of the post-traumatic elbow without evidence of fracture.
Posterior Fat Pad Sign as an Indicator of Occult Elbow . The posterior fat pad sign in association with occult fracture of the elbow in children. J Bone Joint Surg 1999;81-A:1429-1433. Consecutive pediatric subjects were prospectively enrolled in this study if they had an elevated posterior fat pad noted on initial radiographic evaluation of the post-traumatic elbow together with the absence of .
Radial Head Fracture These fractures can be subtle and indirect signs are used to infer their presence. A visible posterior fat pat is the most sensitive indicator of an occult fracture. The "sail sign" or displaced anterior fat pad is also used to diagnose occult radial head fractures but is less sensitive than displacement of the posterior fat pad.

How to Read an Elbow X-Ray - Emergency Medicine | NewYork . There is no obvious anterior or posterior fat pad and the radio-capitellar line is intact. The radial head and distal humerus appear fine while there is an obvious proximal olecranon fracture. Use this systematic approach to the elbow radiograph to avoid missing occult fractures of the elbow.
Rapid screening for the posterior fat pad sign in suspected . Fractures of the elbow are sometimes not visualized on plain radiographs and the only sign of an occult fracture is an elevated posterior fat pad that normally sits within the olecranon fossa . Thus the posterior fat pad sign which implies joint effusion is highly sensitive for fracture in the setting of elbow trauma [ 5 – 7 ].
Sail sign (elbow) | Radiology Reference Article | Radiopaedia.org Elevation of the anterior fat pad usually heralds the presence of an intra-articular fracture. In adults this is usually a radial head fracture whereas in children the commonest cause of a raised elbow fat pad is a supracondylar fracture. Where a fat pad is raised and no fracture is demonstrated an occult fracture should be suspected.

Elbow Effusions in Trauma in Adults and Children : American . These fat pads can be elevated by the presence of fluid in the joint caused by an acute fracture. We wondered how often an occult fracture was present. For years residents were taught that elbow effusions without a visible fracture are synonymous with an occult fracture in the setting of trauma. Indeed multiple articles have indicated a .
The role of fat pad sign in diagnosing occult elbow fractures . In 1954 Norell described the 'fat pad sign' for the first time. This refers to the radiological visualization of the elbow fatty tissue. This is a prospective study with the aim of clarifying the relation between the presence of a positive fat pad sign on the lateral radiograph and the type of injury verified on MRI.
Fat Pad Signs in Elbow Trauma - Idaho State University 1-A1.) The anterior fat pad can be elevat-ed in a patient with an occult fracture. This is known as the “sail sign” due to the triangular sail-like appearance of the anterior fat pad.4 (See Fig. 1-B1.) Posterior Fat Pad In contrast the posterior fat pad is located deep within the concavity of the olecranon fossa and is not normally visu-
Explorative study of the sensitivity and specificity of the . To investigate the value of post-traumatic pronator quadratus (PQ) fat pad sign as a reliable predictor of subtle wrist fractures. This was a prospective study of 68 patients undergoing X-ray for traumatic wrist injuries and subsequent MRI. The reliability of a positive PQ fat pad sign on X-ray defined as either raised interrupted or obliterated was evaluated in detection of subtle wrist .
EMRad: Can’t Miss Elbow Injuries Occult Radial Head Fracture. Epidemiology: This is the most common elbow fracture in adults. 2 They typically occur from a fall onto outstretched hands (FOOSH).

ELBOW: Don’t be a FOOL Fat pad without fracture: Occult fractures •Occult fracture? Suspicious….. – 17% (9/54) fracture on follow up films (Donnelly LF et al. AJR 1998) • 78% (7/9) higher likelihood of fracture if persistent joint effusion on follow-up – 76% (34/45) fracture on follow up films (Skaggs DL & Mirzayon R. J Bone Joint Surg Am. 1999)
Radiology In Ped Emerg Med Vol 1 Case 19 View AP and lateral view above: Discussion & Teaching Points: 1) A swollen elbow usually contains a fracture injury. In some instances a joint effusion (posterior fat pad sign or enlarged anterior fat pad sign) can be seen in the absence of a visible fracture. Occult fractures may still be present in such cases. It is prudent to treat such an .
PEM Pearls: Ultrasound for Diagnosing Occult Supracondylar . 12 If there is no obvious fracture on x-rays the patient may have an occult fracture; look for secondary radiographic signs including a posterior fat pad sign an enlarged anterior fat pad or ‘sail sign’ or malalignment. Occult supracondylar fractures (those with initial normal radiographs that are later diagnosed in follow up) make up 2 .
Supracondylar Humerus Fractures | Pediatric Orthopaedic . Type 4 – a controversial category describing a fracture that is unstable in flexion and extension implying a lack of intact periosteum.
