It is important to know the sequence of appearance since the ossification centers always appear in a strict order. A fracture should be splinted in a position of function until outpatient orthopedic follow-up is available. Monteggia injury1,2. Fracture of the lateral humeral condyle109 The order is important. If the 3 bones do not fit together perfectly due to growth abnormalities, abnormal weight distribution on areas of the joint occur causing . Radiocapitellar line (on AP and lateral) 9 Patients usually present with lateral elbow pain after a FOOSH with the forearm in supination, creating a varus force on the elbow.

They do this by taking a single X-ray of the left wrist, hand, and fingers. Occasionally a minor variation in the sequence may occur. The case on the left shows a fracture extending into the unossified trochlear ridge. Check for errors and try again. Supracondylar fracture with minimal displacement. They are not seen on the AP view. Capitellum fractures are uncommon. The elbow is stable. On the left the anterior humeral line passes through the anterior third of the capitellum. That being said, it can also occur due to birth trauma- both vaginal delivery and cesarean section. Eventually each of the fully ossified epiphyses fuses to the shaft of its particular bone. Sometimes this happens during positioning for a true lateral view (which is with the forearm in supination). The most common is a fracture of the olecranon. older than 2.5 years old due to the small size. Slips and falls are the most common reason a baby or toddler fractures a bone. A considerable force is required to cause this fracture, and since young infants are not mobile enough to produce this force, non-accidental trauma must be suspected in these cases. minimally displaced, look at areas where common injuries occur first (distal humerus and radial neck), mechanism: fall onto a hyperextended elbow, there may be posterior displacement of the distal segment, mechanism: usually varus force applied to an extended elbow, prone to displacement due to the pull of forearm extensors, mechanism: FOOSH with extended elbow and supinated forearm, mechanism: either a direct blow, fall on an outstretched hand with flexed elbow, avulsion fracture or stress fracture.

In dislocation of the radius this line will not pass through the centre of the capitellum. windowOpen.close(); is described as a positive fat pad sign (figure). The other half of the screw is stuck in the bone and will probably never come out. 5 out of 5 stars . I = internal epicondyle A site developed for Postgraduate Orthopaedic Trainees preparing for the FRCS Examination in the United Kingdom. The forearm is the part of the arm between the wrist and the elbow.

Radial neck fractures aswell as radial head dislocations are in 50% of the cases associated with other elbow injuries. Treatment Most of these fractures consist of greenstick or torus fractures. Once displaced fractures consolidate in a malunited position, treatment is difficult and fraught with complications. (AP) and lateral elbow radiographs of 6-year-old girl with type 2A supracondylar humerus fracture with no rotational deformity on AP view . Malalignment usually indicates fractures. An elbow joint effusion without a visible fracture seen on radiographs can suggest an occult fracture and should prompt further evaluation. So, if you see the ossified T before the I then the internal epicondyle has almost certainly been avulsed and is lying within the joint ie it is masquerading as the trochlear ossification centre (see p. 105).

These patients are treated with casting. This order of appearance is specified in the mnemonic C-R-I-T-O-E There was no further testing they could do to conclusively determine it was cancer, but they felt that was much more likely the case than an infection. Two anatomical lines101 Elbow X-rays are taken from the front and side. Since the medial epicondyle is an extra-articular structure a fracture or avulsion will not automatically produce a positive fat pad sign.
Is the medial epicondyle slightly displaced/avulsed? In theory, X-rays are allowed to make children over 14 years old. This may be attributed to healthcare providers . Aspiration of the elbow joint with blood cultures, Closed reduction via supination and flexion, Closed reduction via longitudinal traction, Placement into long arm splint with no reduction required.

X-ray results are normal in someone with nursemaid's elbow. Olecranon fractures occur in children from a direct blow to the elbow or from a FOOSH. The bones on the X-ray image are compared with X-ray images in a standard atlas of bone development. However fractures anywhere along the ulna have been reported. This article lists examples of normal imaging of the pediatric patients divided by region, modality, and age. On the left more examples of the radiocapitellar line. As discussed above they are associated with radial neck fractures and radial dislocations. A pulled elbow is common. While fractures of the lateral condyle occur in children between the age of 4 -10 years, isolated fractures of the capitellum are seen in children above the age of 12.
