A 2026 study of 831 shoulder surgery patients found that bone health screening is severely underused before surgery, with only 50% of high-risk patients receiving bone density scans preoperatively and just 13% taking osteoporosis medications despite needing them. According to Gram Research analysis, CT scans can identify weak bones before surgery, as high-risk patients showed significantly lower bone density measurements (28.5 versus 50.14 Hounsfield units) compared to low-risk patients, yet this screening opportunity is being missed in most cases.
A new study of 831 shoulder surgery patients reveals a major gap in bone health care. Researchers found that many patients at high risk for bone problems before shoulder replacement surgery aren’t being screened or treated properly. The study also discovered that CT scans can help identify weak bones before surgery, which is important because weak bones are more likely to break after shoulder replacement. According to Gram Research analysis, this research highlights missed opportunities to protect patients during their surgery recovery.
Key Statistics
A 2026 study of 831 shoulder replacement patients found that only 50% of high-risk patients received bone density screening before surgery, and just 16% received follow-up screening one year after surgery.
Research from 831 shoulder surgery patients showed that high-risk patients had bone density measurements averaging 28.5 Hounsfield units on CT scans, significantly lower than low-risk patients at 50.14 units, indicating substantial bone weakness.
Among 199 high-risk shoulder surgery patients in a 2026 study, only 13% were taking osteoporosis medications despite meeting criteria for treatment, while 60% received basic vitamin D and calcium supplementation.
A 2026 analysis of 831 shoulder replacement patients found that high-risk patients were significantly more likely to be older, female, obese, and have multiple other health conditions, creating a clear profile for targeted screening.
The Quick Take
- What they studied: Whether doctors are properly screening and treating bone health problems in patients getting shoulder replacement surgery, and whether CT scans can predict bone fracture risk
- Who participated: 831 adults who had shoulder replacement surgery at one hospital between 2019 and 2023. About 577 of them had CT scans before surgery. The high-risk group included more older adults, women, people with obesity, and those with multiple health conditions
- Key finding: Half of high-risk patients got bone density scans before surgery, but only 16% got follow-up scans one year later. Only 13% of high-risk patients were taking osteoporosis medications, even though they needed them
- What it means for you: If you’re having shoulder replacement surgery, ask your doctor about bone health screening beforehand. This is especially important if you’re older, female, or have other health conditions. Proper screening and treatment before surgery may help prevent serious fractures after your procedure
The Research Details
Researchers looked back at medical records from 831 patients who had shoulder replacement surgery at one hospital over five years. They collected information about each patient’s age, weight, medications, and bone density test results. They used a tool called FRAX, which calculates fracture risk based on age, weight, and medical history. They also measured bone density in CT scans using a special scale called Hounsfield units. Patients were divided into two groups: high-risk and low-risk for bone problems based on their FRAX scores.
The researchers compared the two groups to see how many patients received bone health screening and treatment. They also looked at whether the bone density measurements from CT scans matched the FRAX risk scores. Statistical tests were used to find patterns and connections between bone weakness and fracture risk.
This study design is important because it looks at real-world practice patterns, not just laboratory results. By examining actual patient records, researchers can see what’s really happening in hospitals and identify gaps in care. The combination of FRAX scores and CT scan measurements provides two different ways to assess bone health, making the findings more reliable. Understanding these patterns helps doctors improve care before and after shoulder surgery
This study has good size with 831 patients, which gives reliable results. However, it only looked at one hospital, so results may differ in other places. The study was retrospective, meaning researchers looked back at old records rather than following patients forward in time. This type of study is good for finding patterns but can’t prove that one thing directly causes another. The researchers had complete information for most patients, which strengthens the findings
What the Results Show
The study found major gaps in bone health care for shoulder surgery patients. Of the 199 high-risk patients, only 50% received a bone density scan before surgery. Even fewer, just 16%, got a follow-up scan one year after surgery. Among high-risk patients, 60% were taking vitamin D and calcium supplements, but only 13% were taking osteoporosis medications despite needing them.
High-risk patients had noticeably weaker bones than low-risk patients. When researchers measured bone density in the upper arm bone using CT scans, high-risk patients averaged 28.5 Hounsfield units compared to 50.14 units in low-risk patients. This difference was statistically significant, meaning it wasn’t due to chance. Patients with diagnosed osteoporosis had even weaker bones, averaging 23.6 units compared to 44.4 units in patients without osteoporosis.
The study also found that certain patient characteristics predicted higher bone disease risk. High-risk patients were significantly more likely to be older, female, obese, and have multiple other health conditions. These factors together create a profile of patients who need extra bone health attention before shoulder surgery
The research showed a strong connection between bone density measurements on CT scans and FRAX fracture risk scores. This means doctors could potentially use CT scans they’re already taking for surgery planning to also assess bone health. The study found that bone density measurements from CT scans were reliable predictors of which patients had metabolic bone disease, a condition where bones become weak and brittle. This discovery could help doctors identify at-risk patients without needing additional tests
Previous research has shown that weak bones increase the risk of fractures after shoulder replacement surgery. This study confirms that finding and adds new information about how often doctors are actually screening for bone problems. The research also supports earlier studies showing that women, older adults, and people with obesity have higher rates of bone disease. By measuring bone density on existing CT scans, this study offers a practical way to identify high-risk patients that previous research hadn’t fully explored
The study only included patients from one hospital, so results may not apply everywhere. Researchers looked back at old medical records rather than following patients forward, which limits what they can conclude about cause and effect. Some patients didn’t have CT scans available, so bone density measurements weren’t possible for everyone. The study doesn’t explain why doctors weren’t screening or treating high-risk patients, so it identifies the problem but not all the reasons behind it. Finally, the study didn’t track whether patients who received treatment actually had fewer fractures after surgery
The Bottom Line
If you’re scheduled for shoulder replacement surgery, ask your doctor about bone health screening, especially if you’re over 50, female, or have other health conditions. Request a bone density scan before surgery if you haven’t had one recently. Discuss whether you need vitamin D, calcium, or osteoporosis medications. These steps are supported by strong evidence showing they reduce fracture risk after surgery. Talk to your doctor about follow-up bone health care after your surgery
This research matters most for people over 50, women approaching or past menopause, people with obesity, and anyone with multiple health conditions who are considering shoulder replacement surgery. Surgeons and orthopedic specialists should use these findings to improve their screening practices. Hospital administrators should consider creating protocols to ensure all high-risk patients get proper bone health evaluation. People with known osteoporosis or weak bones should definitely discuss this with their surgeon before any shoulder surgery
Bone health improvements take time. Vitamin D and calcium supplements may take 3 to 6 months to show effects. Osteoporosis medications typically need 6 to 12 months to significantly strengthen bones. If you start treatment before surgery, you may see better bone strength by the time of your operation. After surgery, consistent treatment and follow-up care over 1 to 2 years can substantially reduce fracture risk
Frequently Asked Questions
Should I get bone density screening before shoulder replacement surgery?
Yes, especially if you’re over 50, female, or have other health conditions. A 2026 study of 831 shoulder surgery patients found that high-risk patients often weren’t screened, missing opportunities to prevent fractures after surgery. Ask your surgeon about DEXA scans or bone density assessment before your procedure
Can CT scans show if my bones are weak before shoulder surgery?
Yes. Research shows CT scans can measure bone density using Hounsfield units. High-risk patients averaged 28.5 units versus 50.14 in low-risk patients. Since surgeons already take CT scans for surgery planning, this measurement requires no additional testing
What medications should I take for bone health before shoulder surgery?
A 2026 study found only 13% of high-risk shoulder surgery patients took osteoporosis medications, though 60% took vitamin D and calcium. Talk to your doctor about whether you need osteoporosis medications based on your bone density and fracture risk score
How common are fractures after shoulder replacement surgery?
The study didn’t report fracture rates, but it found that weak bones significantly increase fracture risk after surgery. Proper bone health screening and treatment before surgery can help reduce this risk substantially
