An unsettling trend is quietly taking hold in hospitals across the United States.
A recent investigation has uncovered a troubling surge in life-changing amputations across the country, with a surprising demographic experiencing a particularly notable rise in recent years.
What is even more alarming is that these incidents often involve more severe amputations, such as the removal of an arm or the upper leg above the knee.
Researchers from Mass General Brigham and the University of California, San Francisco conducted a study examining US hospital admissions from 2016 to 2022 to assess changes in amputation rates over time.
During this period, there was an overall increase in amputations by 35.3%, rising from 58.9 to 79.7 per 10,000 hospitalizations. However, among patients with opioid-related cases, the escalation was significantly more pronounced, with a staggering 66% increase, surging from 55.6 to 92.3 per 10,000.
The most significant rises in amputations connected to opioid use were observed in regions of the Northeast and West.
Opioids â a class of drugs used to treat severe pain â include prescription medications like fentanyl and oxycodone, as well as illicit drugs such as heroin.
While highly effective for pain management, they also carry a high risk of dependence and addiction.
Widespread prescribing in the 1990s helped fuel a major public health crisis in the US, later driven further by a shift from prescription pills to cheaper street drugs in the 2010s.
Many of these drugs are injected, which raises the risk of serious skin, soft tissue and bone infections that can spread quickly without prompt medical care. In severe cases, those infections can lead to devastating medical emergencies that require intensive treatment, including amputations.
Diabetes-related complications still account for about 80% of lower-limb amputations nationwide. Out of more than 41 million adult hospitalizations analyzed in this study, roughly 3% were opioid-related.
But the rise in lost limbs linked to opioid use highlights another troubling layer of a epidemic now entering its fourth decade.
Study authors pointed to the growing presence of xylazine â a veterinary tranquilizer sometimes mixed into street drugs, nicknamed “tranq” â as a possible factor behind the increase. The drug has been linked to severe tissue damage and hard-to-treat wounds, and may be contributing to cases of limb loss, particularly in Northeastern states where it is more common.
However, cases also rose in areas where xylazine is less common, suggesting other factors are also at play, including limited access to wound treatment and housing instability, researchers said.
Rising amputation rates are just part of the wider toll of the opioid epidemic, widely described as one of the most severe public health crises in US history.
Across the country, an estimated 5.9 million Americans ages 12 and up â about 2.1% of the population â are living with opioid use disorder (OUD), according to the National Center for Drug Abuse Statistics.
Misuse of these drugs can lead to wide reaching consequences, including straining relationships, hurting performance at work or school, and leading to serious health and legal consequences.
While the chronic condition is treatable, research shows many people donât receive the help they need. In fact, CDC data shows that fewer than 25% of people with opioid use disorder receive medications that can reduce cravings, ease withdrawal symptoms and lower the risk of overdose death.
Since the opioid epidemic was declared a public health emergency in 2017, it has claimed more than half a million lives, according to KFF.
But there are signs the tide may be turning. Opioid overdose deaths fell sharply from 2023 to 2024, largely driven by a decline in fentanyl-related deaths, and provisional data suggests the downward trend continued into 2025.
In New York state, opioid-related deaths are down 51.9% since 2022.
