Damage to progestin containing contraceptive implants has been reported for Implanon® rods but there appear to be few reports of damage to Nexplanon® rods. This report describes 2 cases of Nexplanon® rod breakage in an 18-year-old female and a 25-year-old female. The literature regarding damaged progestin implants is reviewed. These reports often involve an alteration in menstrual bleeding pattern and patients frequently request removal of bent or broken implants. The overall incidence of rod breakage and impact of damaged implants on contraceptive efficacy is not clear. Evidence based guidelines to inform management of suspected damage to contraceptive implants would be helpful. In the meantime, a shared decision-making process offering removal and replacement of damaged implants would seem reasonable.
据报道，依伴侬（Implanon®）皮下埋植剂中的孕激素成分会受到损害，但有关奈丝盼（Nexplanon®）皮下埋植剂受损的报告似乎较少。本报告描述了1例18岁女性和1例25岁女性的奈丝盼（Nexplanon®）皮下埋植剂断裂病例。本文对有关受损孕激素皮下埋植剂的文献进行了综述。这些报告通常涉及月经出血模式的改变，患者经常要求取出弯曲或断裂的皮下埋植剂。皮下埋植剂断裂的总体发生率以及受损皮下埋植剂对避孕效果的影响尚不清楚。基于证据的指导方针有助于指导对疑似受损避孕皮下埋植剂的处理。与此同时，提供取出和更换受损皮下埋植剂的共同决策过程似乎是合理的。
