The lateral structures like the capitellum and the radius will move anteriorly, while a medial structure like the medial epicondyle will move posteriorly. /* ]]> */ But X-rays may be taken if the child does not move the arm after a reduction. The other important fracture mechanism is extreme valgus of the elbow. Capitellum fractures are uncommon. Clinical impact guidelines: the I in CRITOL Normal children chest xrays are also included. An elbow joint effusion without a visible fracture seen on radiographs can suggest an occult fracture and should prompt further evaluation. This website uses cookies to improve your experience. It is made up of two bones: the radius and the ulna. Two anatomical lines101 When checking the position of the internal epicondyle on the AP radiograph: If part of the epicondyle is covered by part of the humeral metaphysis then an avulsion has not occurred. Boys' growth plates close by around the time they turn 16-17 on average. (Table 1 and Fig 6), The medial epicondyle fuses to the shaft of the humerus at 13 years for females and 15 years for males. If a positive fat pad sign is not present in a child, significant intra-articular injury is unlikely. 25% will show radiocapitellar line slightly lateral to center of capitellum. At that point growth plates are considered closed. However, obtaining bilateral films should used selectively, not routinely. The posterior fat pad is not visible on a normal radiograph because it is situated deep within the olecranon fossa and hidden by the overlying bone. (SBQ13PE.4) A 7-year-old with a history of an elbow injury treated conservatively presents for evaluation of ongoing elbow pain. The most common is a fracture of the olecranon. They should stay still for 2-3 seconds while each X-ray is taken so the images are clear. (OBQ07.69) . X-rays of a patient's uninjured elbow are a good indicator of normal. Kids will say it hurts in the wrist, forearm, or elbow. In this review important signs of fractures and dislocations of the elbow will be discussed. The rule to apply:On the AP radiograph a normally positioned epicondyle will be partly covered by some of the humeral metaphysis. Nursemaid's Elbow - OrthoInfo - AAOS A major avulsion is easy to overlook when an elbow has been transiently dislocated and then reduces spontaneously5,6 because the detached epicondyle may, on the AP radiograph, be mistaken for the normally positioned trochlear ossification centre (p. 105). Supracondylar fracture106 The avulsed medial epicondyl was found within the joint and repositioned and fixated with K-wires. 102 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. Overprojection of the capitellum on the humeral metaphysis may simulate a lateral condyle fracture (figure). They ossify in a sex- and age-dependent predictable order. This is a repository of example radiographs (x-rays) of the pediatric skeleton by age.
