WHAT'S KNOWN ON THIS SUBJECT: Self-embedding behavior is an extreme form of self-injury involving the insertion of inanimate objects into the soft tissues, either under the skin or into muscle. To date, no case series data on this behavior among adolescents has been described in the pediatric medical literature.
WHAT THIS STUDY ADDS:Goals of this study are to begin to develop a clinical picture of adolescents who engage in selfembedding behavior, resulting in an understanding that allows practitioners to pursue rapid and targeted intervention to interrupt the cycle of self-harm and institute appropriate longterm therapy.abstract OBJECTIVE: The goal of this study was to define self-embedding behavior (SEB), develop a clinical profile of adolescents who engage in SEB, and emphasize the importance of rapid, targeted, and effective identification and intervention.
METHODS:As part of a retrospective study with a database evaluating 600 patients percutaneously treated for soft-tissue foreign body removal, adolescents were identified with self-embedded soft-tissue foreign bodies. We describe patients' gender, age, and psychiatric diagnoses; SEB age of onset, frequency, and self-reported reasons; and the number, type, location of, and removal technique for objects.
RESULTS:Eleven patients (9 females) who engaged in SEB were identified. Ten of the 11 patients were members of a group home or psychiatric facility at the time they engaged in SEB. All patients had previous and multiple psychiatric diagnoses. SEB mean age-of-onset was 16 years, and mean number of SEB episodes per patient was 1.9. The most common self-reported purpose for SEB was suicidal ideation (6 of 8 [75%]) versus nonsuicidal ideation (2 of 8 [25%]), with 3 cases lacking this documentation. The mean number of objects embedded in a single episode was 2.4, usually composed of metal and embedded in the arm. Seventy-six foreign bodies were percutaneously removed (using ultrasound or fluoroscopic guidance), including metal, glass, wood, plastic, graphite, and crayon.
CONCLUSIONS:SEB is an extreme form of self-injury requiring aggressive and timely interdisciplinary assessment and treatment. An understanding of SEB allows medical professionals to pursue rapid, targeted, and effective intervention to interrupt the cycle of self-harm and institute appropriate long-term therapy.
