Interpret elbow x-rays using a standard approach; Identify clinical scenarios in which an additional view might improve pathology diagnosis; Why the elbow matters and the radiology rule of 2's The Elbow. indications. 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. The coronal alignment of her elbows in extension is symmetric. When the elbow is dislocated and the medial epicondyle is avulsed, it may become interposed between the articular surface of the humerus and the olecranon (figure).

Skeletal surveys are performed in cases of: suspected non-accidental pediatric skeletal injury, post-mortem before an autopsy in cases of suspected sudden infant death syndrome (SIDS) to exclude traumatic skeletal injury or skeletal abnormalities indicative of an underlying naturally occurring disease. When the trochlea is not yet ossified the avulsed fragment may simulate a trochlear ossification centre. But X-rays may be taken if the child does not move the arm after a reduction. olecranon. and more. This is not about possible pathologies, because usually the dose of radiation and the duration of the procedure are adjusted so that they can not cause significant harm.

The fat is visualised as a dark streak amongst the surrounding grey soft tissues. }); Casting extends above the elbow and down to the wrist, leaving the fingers free and the arm placed in a sling. The elbow is stable. The low position of the wrist leads to endorotation of the humerus. The elbow becomes locked in hyperextension. When the forces have more effect on the humerus, the extreme valgus will result in a fracture of the lateral condyle. Tessa Davis. Medial Epicondyle avulsion (3).

The growth plate usually has a different oblique course compared to a fracture-line. No fracture. Be careful: in very young children the ossification within the cartilage of the capitellum might be minimal (ie normal and age related), and so is insufficiently calcified and does not allow application of the above rule. Nerve injurie almost always results in neuropraxis that resolves in 3-4 months. There are six ossification centres. They require reduction by closed or if necessary open means. Normal pediatric bone xray. In the older child, these fractures are due to a direct blow to the lateral epicondylar region and are usually associated with other injuries of the elbow. A normal Baumann angle is generally considered to be in the range of 70-80. When a major displacement of the internal epicondyle occurs the bone can become trapped within the elbow joint. Since these fractures are intra-articular they are prone to nonunion because the fracture is bathed in synovial fluid.
