Listen to the evolving economics of prosthetics

Software subscriptions, licenses, and climate control systems add to 3D printing costs

Although the sharing of designs and reduced manual labor suggested the fabrication of prosthetics would be facilitated by 3D printing, particularly in developing regions, software and hardware requirements have posed hurdles to achieving this goal. While some insurance companies have refused to cover 3D-printed limbs, they are covered by Medicare.

Organ transplants can come with a price tag of more than $2M without insurance

According to 2025 report data that was graphically represented by Statista, average costs for organ transplants can be as steep as $2.3M for a double lung transplant and $1.9M for a heart. These figures are based on what was actually charged to insurance companies—not what individual patients paid. Following the actual transplant there are also additional costs associated with the procedure, including lifelong immunosuppressant drugs.

The brain doesn't seem to massively rewire following amputation—upending earlier beliefs about phantom pain

The findings, published in 2025, traced three amputees' brain-body maps and how they respond to body part movements—both before and after scheduled arm amputations. The unexpected neural stability suggests that the unchanged pathways for the missing limbs may explain why people continue to feel them so acutely.

Breaking down the knee's anatomy

The human knee is a remarkably complex structure carrying the full weight of the body throughout a person’s life while allowing a number of complex twists, flexes, and extensions. It's also one of the body's biggest weaknesses—the location of chronic pain and replacement surgeries for millions of Americans.

Black Americans with diabetes have amputation rates three times higher than average

Annually, 130,000 US diabetics undergo amputations due to complications from diabetes, with many patients located in low-income and uninsured neighborhoods. More than half of US diabetics who lose lower limbs are not subject to pre-surgery angiograms, imaging that shows blood flow blockages to determine if (and where) amputation is necessary.

Recent research found that the brain doesn't seem to massively rewire following amputation—upending earlier beliefs about the cause of phantom limb pain.

Implanted neurotechnology can leave users vulnerable when manufacturers go under

Despite providing relief from neurological conditions, patients are left stranded when the companies that make these devices shut down. The lack of regulation means patients often face technical failure, insurance battles, or risky surgeries to maintain their quality of life.

Limb regeneration research may lead to treatments for arthritis

For scientists pursuing the cure for arthritis, the holy grail of discoveries lies in how to regrow healthy cartilage inside human joints. While this feat has so far resisted our best scientific attempts, there are plenty of other human tissues—such as the liver and fingertips—that will successfully regenerate.

One estimate values concierge services at $38.9B by 2032

Data Horizons Research put the value of this global market at $18.9B in 2021, but anticipates massive growth by 2032, with North America comprising the majority of the market. Chronic health conditions, their analysis suggests, will be a contributing factor to this growth as medically complex individuals seek more personalized care.

In a first, eye prosthesis has restored sight to macular generation patients

In a clinical trial, 27 of 32 participants with advanced macular degeneration regained enough vision to read books, food labels, and subway signs about a year after receiving a prosthetic retina device. This is the first device to restore functional vision to patients with incurable vision loss, though in this case they can only see in black and white, with no shades in between.

The lifetime costs of caring for a dog can run anywhere from $16,440 to $52,075
