Increasing Prevalence of Xylazine and Worsening Upper-Extremity Wounds in Injection Drug Use: A Local Phenomenon With National Implications.

The rising presence of xylazine in Philadelphia's fentanyl supply has led to various upper-extremity complications in individuals who inject drugs. Sociogeographic trends predict that our current local phenomenon will spread nationally. We aim to discuss the drug's impact on clinical presentation and patient care via a cohort of five patients with upper-extremity wounds related to drug use. Interventions included local wound care, revascularization, compartment release, free flap reconstruction, and amputation. Successful treatment of these patients, who are often in challenging psychosocial environments, requires an individualized and interdisciplinary approach including surgical services, infectious disease, wound care, addiction medicine, psychiatry, social services, and prosthetic services.
