Abstract
BACKGROUND: The etonogestrel contraceptive implant (Implanon®) is an effective, long-acting subdermal method of hormonal contraception for women. CASE: We describe a case of forearm pain and hypoesthesia associated with the insertion of the Implanon® contraceptive implant in a healthy 26-year-old female. These symptoms were due to direct implant contact with the medial cutaneous nerve of the forearm. The importance of correct insertion technique is discussed. CONCLUSION: Care should be taken to avoid nerve injury during insertion of subdermal contraceptive implants. An understanding of regional anatomy and the correct insertion technique will prevent insertion-related complications. Nexplanon® has been developed to replace Implanon®. It has a redesigned applicator intended to increase insertion accuracy.
