In 2017, Global Pediatric Health published a case report series associated with the use of long-acting reversible contraceptives, specifically the etonogestrel implant.
In November 2020, the makers of the etonogestrel implant (Merck) recommended a change in practice with the release of a notice to health care providers certified in the training of this product. This mass marketing blast included an updated warning and cautions for prescribers as well as patient information on the potential risks of migration, fracture, and bent devices attributable to trauma or sports. “Broken or Bent Implant (Section 5.16). The addition of the following underlined language: “There have been reports of broken or bent implants, which may be related to external forces (e.g., manipulation of the implant or contact sports) while in the patient’s arm. There have also been reports of migration of a broken implant fragment within the arm.”
Clearly the etonogestrel subdermal hormonal implant is an effective form of contraception and particularly beneficial in nonadherent sexually active teens who struggle to remember oral contraceptives. But it is important to be aware of this alert. Little is known about the type of trauma or rate of external force required to cause migration, fracture, or bend implants. This update requires adequate counseling of potential risks and complications of the etonogestrel implant, including the risk of migration, fracture, or bent devices specifically in the event of contact sports and trauma.
