When treating humeral shaft fractures, which approach do you prefer? Are you in the traditionalist camp: functional bracing, popularized by Sarmiento and beloved for its simplicity, low complication rates, and avoidance of the operating room?
Or do you sit with the modernists, armed with plates, screws, and the conviction that a well-fixed humerus makes for a happier patient.
Functionally speaking, the literature has long suggested that both strategies produce fairly comparable outcomes. But what about the other metric that increasingly influences modern healthcare decisions —cost?
A prespecified economic evaluation of the Finnish Shaft of the Humerus (FISH) trial set out to answer exactly that question. And the results may surprise even the most brace-loving surgeons.
(If nothing else, the acronym for this study should win an award).
Expensive FISH? Surgery vs. Brace for Humeral Shaft Fractures
The FISH trial enrolled 82 adults with displaced, closed humeral shaft fractures across two Finnish university hospitals between 2012 and 2018. These were mostly working-age patients — average age about 49 — meaning the economic ripple effects of treatment decisions extend well beyond the hospital bill.
Participants were randomized to either surgical fixation (38 patients), typically with plate osteosynthesis, or functional bracing (44 patients), the classic nonoperative approach.
Patients were followed for two years, allowing investigators to track not only clinical outcomes but also the broader economic impact of each treatment strategy.
Instead of focusing solely on hospital costs, the researchers used quality-adjusted life years (QALYs) as their primary measure of value. QALYs attempt to combine both quality and duration of life into a single metric — essentially asking: how much “good health” does a treatment buy?
They measured this using the 15D instrument, a validated health-related quality-of-life tool used in health economics.
The key question: Which treatment delivers more health per euro spent?
Surgery Wins…From Society’s Perspective
When investigators looked at the societal perspective — which includes healthcare costs plus productivity losses such as time off work — the results favored surgery.
In fact, surgery was both more effective and less costly overall.
Here’s how the numbers shook out.
| Treatment | Mean Total Cost | QALYs (6 weeks–2 years) |
| Surgery | €23,680 | 1.776 |
| Functional Bracing | €30,389 | 1.705 |
Surgery saved about €6,700 ($27,434) per patient with surgery. In terms of QALYs, surgeries health benefit was an additional 0.071.
The combined effect produced an incremental net monetary benefit of €9,423 ($10,917) in favor of surgery.
In other words, when lost productivity and societal costs are considered, plating the humerus appears to be the economically dominant strategy.
Why? The answer likely won’t shock anyone who has managed these injuries: return to function and return to work.
Patients treated surgically often mobilize faster, avoid prolonged bracing discomfort, and are less likely to experience delayed union or nonunion requiring later surgery. Those downstream benefits translate into fewer work absences and lower productivity losses.
But…The Hospital Sees It Differently
When investigators looked only at direct healthcare costs, the story flipped.
From a purely hospital or payer perspective, treatment direct healthcare cost for surgery was €10,967 ($12,706), while for bracing it was €4,904 ($5,682).
The divergence between these perspectives highlights one of the central tensions in healthcare economics. Hospitals typically account for direct medical expenses like operating room time, implants, surgical staff and hospital stay, while society also absorbs other costs like lost work productivity, disability payments, and caregiver burden.
In working-age populations — like those in the FISH trial — productivity losses often dwarf medical expenses.
The Clinical Reality
Of course, cost-effectiveness analyses rarely capture the full nuance of clinical practice.
Not every humeral shaft fracture behaves the same way.
Some patients tolerate bracing beautifully and heal uneventfully. Others struggle with malalignment, nonunion and prolonged discomfort. Likewise, surgery also carries its own risks.
So, while economic models are informative, the real-world decision remains more complicated.
What Should Surgeons Take Away?
The FISH trial’s economic analysis delivers several useful insights for practicing orthopedic surgeons.
- Surgery may create broader economic value: For working-age patients, surgical fixation may reduce societal costs by accelerating return to function and work.
- Hospitals and society often value treatments differently: A strategy that saves money for society may still cost more for the healthcare system. Understanding that tension is increasingly important in value-based care environments.
- Functional bracing remains a very reasonable option: Not every patient needs a plate. For individuals with lower functional demands or minimal work disruption, bracing remains cost-effective and clinically sound.
