Self-injurious behavior to the lower extremities among children with atypical development: a diagnostic and treatment algorithm.

Self-injurious behavior is a devastating and persistent condition that results in severe tissue damage, permanent impairment, or, occasionally, death. This aberrant behavior seen in specific childhood syndromes is compounded when the lower limbs are injured. Secondary complications are more frequent, depending on the site of the injury, resulting in significant morbidity and depletion of hospital resources. A substantial body of empirical evidence indicates that this deviant behavior is partly learned and partly of biologic origin. Therefore, this article presents a case study and reviews the components of a biopsychosocial paradigm of treatment for self-inflicted wounds to the lower extremity and formulates a prototypical algorithm for its diagnosis and management.
