Congenital Dislocation of the Head of the Radius

Isolated congenital dislocation of the radial head: Good function in 4 untreated patients after 14–45 years

“…The 2 cases of bilateral anterior dislocation (mother-daughter) seem to have a hereditary basis. Congenital radial dislocation, especially the posterior type, is often associated with a variety of anomalies and syndromes (Almquist et al 1969, Miura 1990,Agnew andDavis 1993, Zidorn et al 1994), but in our cases clinical examination showed no further deformities or anomalies. We had 1 case of unilateral anterior, 1 of unilateral posterior and 2 cases of bilateral anterior radial head dislocation.…”

“…Radial head dislocation presents as congenital dislocations or posttraumatic (Weil 1959, Almquist et al 1969, Miura 1990, Mizuno et al 1991, Wiley et al 1991, Agnew and Davis 1993. In our cases there was no trauma.…”

“…We had 1 case of unilateral anterior, 1 of unilateral posterior and 2 cases of bilateral anterior radial head dislocation. Almquist et al (1969) reported that almost half of congenital radial head dislocations were anterior, almost half posterior and one tenth lateral. Almost half of the dislocations were bilateral.…”

Loeys-Dietz Syndrome with Bilateral Radial Head Dislocations: A Case Report

“…All joint contractures reported have been soft-tissue contractures and not bony deformities. Congenital radial head dislocations have been associated with the Cornelia De Lange syndrome, Klinefelter syndrome, and Mieten syndrome, 11,12 but never in Loeys-Dietz syndrome. Congenital radial head dislocations have a poor prognosis after surgical reduction and are best left alone.…”

Larsen's Syndrome:Report of Three Cases in the One Family, Mother and Two Offspring

“…As regards the aetiopathogeny of the disorder, the majority of authors (Almquist et al 1969, Boni et al 1974, Steel & Kohl 1972 concur that it must he a generalized mesenchymal alteration. This opinion, however, has not been proven to date.…”
