title: Management of uterine adhesions with 'Massouras Duck's Foot' and 'Butterfly' IUDs.
abstract: The Massouras Duck's Foot (MDF) IUD and the Butterfly IUD have been clinically evaluated.  The MDF, which is Y-shaped, has 2 or 3 horizontal arms on a vertical stem and 2 triangular wings, in between the 'V'.  When inserted after curettage, it prevents intrauterine or intracervical adhesions.  The fan-shaped Butterfly IUD has 2 overlapping wings, thereby facilitating adjustment of the IUD to variable uterine cavities.  Its wing span occupies the entire uterine cavity when inserted according to the instructions.  Both IUDs are made of polyethylene plastic with barium sulfate.  Several substitutions for barium sulfate are suggested, e.g., copper, silver, hormones, biodegradable polymers.  The high antifertility action of these IUDs is due primarily to their occupancy of the entire uterine cavity.
