Supracondylar fractures (2)If there is only minimal or no displacement these fractures can be occult on radiographs. Posterolateral displacement of the distal fragment can be associated with injurie to the neurovascular bundle which is displaced over the medial metaphyseal spike. Out of these cookies, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. The most important finding is the posteromedial displacement of the radius and ulna in relation to the distal humerus. There are pads of fat close to the distal humerus, anteriorly and posteriorly. The rotation of the fracture fragment gives a typical appearance on the X-rays (arrow). Chacon D, Kissoon N, Brown T, Galpin R. Use of comparison radiographs in the diagnosis of traumatic injuries of the elbow. When a major displacement of the internal epicondyle occurs the bone can become trapped within the elbow joint.

Interpreting Elbow and Forearm Radiographs Taming the SRU If there is no displacement it can be difficult to make the diagnosis (figure). Usually there is some displacement and the anterior humeral line will not pass through the centre of the capitellum but through the anterior third or even anterior to the capitellum (figure). Occasionally doctors request an X-ray of the opposite elbow as well (the uninjured side) for comparison. 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 medical term for the injury is "radial head subluxation." Because a young child's bones and muscles are still developing, it typically takes very . A caveat:Occasionally a child in pain will hold the forearm in a position of slight internal rotation. // If there's another sharing window open, close it. return false; of the capitellum or in front of the capitellum due to posterior bending of the distal humeral fragment. If part of the epicondyle is covered by part of the humeral metaphysis then an avulsion has not occurred. Rotation will project the metaphysis of the humerus away from a normally positioned epicondyle. Your elbow bones include the upper bone of your elbow joint (humerus) and the lower bones of your elbow joint (radius and . Osteoporosis T-Score: Do I Have a Normal Bone Density? - Verywell Health I = internal epicondyle Distention of a structurally intact joint causes displacement of the fat pads - the posterior fat pad moves posteriorly and superiorly and becomes visible; the anterior fat pad becomes more sail-like.4 (Fig 2). Radial Head and Neck Fractures in children are relatively common traumatic injuries that usually affect the radial neck (metaphysis) in children 9-10 years of age.

Normal alignment: when drawn along the anterior cortex of the humerus, in most normal patients at least one third of the ossifying capitellum lies anterior to this line. The condition is cured by supination of the forearm. A major avulsion is easy to overlook when an elbow has been transiently dislocated and then reduces spontaneously 5 , 6 because the detached epicondyle may, on the AP radiograph, be mistaken for the normally . The medial epicondyle is an apophysis since it does not contribute to the longitudinal growth of the humerus. if it does not, think supracondylar fracture.

Upper Extremity : Lower Extremity: Age: Hand/Wrist: Forearm: Elbow: Humerus: Cervical Spine: Chest: Pelvis: Femur: Knee: Tibia/Fibula . I before T. Though the CRITOL sequence may vary slightly there is a constant: the trochlear (T) centre always ossifies after the internal epicondyle. Normal alignment. Below are eight sequential steps to aid in the radiographic recognition of occult signs of injury. I before T. Though the CRITOL sequence may vary slightly there is a constant: the trochlear (T) centre always ossifies after the internal epicondyle.
