title: Transphyseal elbow fracture in newborn: review of literature.
abstract: Transphyseal elbow fracture is a rare entity in newborns, and in the last century, only case reports or small case series have been published; however, precise epidemiological data lack. Such fractures occur more often in emergency Caesarian section or vaginal delivery. The differential diagnosis with elbow dislocation can be challenging. Radiography, arthrography, magnetic resonance, ultrasound or a combination of these have already been described to make diagnosis, but guidelines for the management of this injury in the neonate are not well established. A review of the literature of the last century about distal transphyseal fracture of the humerus in newborns was performed. A bibliographic search was conducted accessing usual medical databases. The work-up methods, treatments, results at follow-up and the rate of complications were collected. Twenty case reports or small retrospective case series reporting a total of 33 cases were included. A posteromedial displacement of the radioulnar complex was found in 21 elbows (64 %). Four patients (12 %) underwent surgical treatment, whilst 29 (88 %) were managed without surgery. An attempt of reduction was reported in 23 cases (69 %). At follow-up, 88 % recovered completely the carrying angle and 80 % range of motion. A relationship between the type of treatment (conservative or surgical, with attempt of reduction or not) and results at follow-up could not be demonstrated. The most common complication was cubitus varus. Transphyseal elbow fractures are rare among newborns. Regardless of the treatment choice, such lesions are in most cases associated with a good prognosis.
