[Direct measurement of cotyloid anteversion of a total hip prosthesis. Value of Arcelin's surgical lateral image]. / Mesure directe de l'antéversion cotyloïdienne d'une prothèse totale de hanche. Intérêt du cliché de profil chirurgical d'Arcelin.

Measurement of anteversion of cotyle of total hip prosthesis generally involves projection of equatorial guide included in cotyloid piece. Direct measurement of cotyloid anteversion on Arcelin's surgical lateral image showed this method to be a simple, reliable, direct procedure for determination of cotyloid anteversion of total hip prosthesis.
