Arthritis Awareness Month is an important time to shed light on joint health—especially conditions like osteoarthritis that affect millions of women. While osteoarthritis is commonly associated with joint pain and stiffness, there is another critical piece of the puzzle that often goes overlooked: bone health. At Cary OB/GYN, we believe in a comprehensive approach to women’s wellness, including understanding how bone density plays a role in long-term mobility and quality of life.
“From the moment I walked in for my first pregnancy visit, Courtney made all the difference. She created an atmosphere that felt warm, welcoming, and genuinely caring. I wasn't just another patient, but truly seen and supported. She took her time, answered every question with patience, and made sure I felt comfortable and confident every step of the way. There's something powerful about being in the care of someone who not only knows what they're doing but also leads with compassion and that's exactly what she does. I left my appointment feeling safe, reassured, and in excellent hands. I'm beyond grateful to have her as part of this journey. If you're looking for someone who combines professionalism with heart, Courtney is truly exceptional.”

What Is Osteoarthritis?
Osteoarthritis (OA) is the most common form of arthritis and is considered a degenerative joint disease. It occurs when the protective cartilage that cushions the ends of bones gradually wears down over time. This leads to symptoms such as joint pain, stiffness, swelling, and reduced range of motion.
As osteoarthritis progresses, the underlying bone can also change. Research shows that OA involves not just cartilage damage, but also alterations in the bone beneath the joint (called subchondral bone), which may affect how the disease develops and progresses. (Springer)
Osteoarthritis most often affects weight-bearing joints such as the hips, knees, and spine—areas that are also critical for mobility and independence.
Why Women Are at Higher Risk
Women are more likely than men to develop osteoarthritis, particularly after menopause. Hormonal changes—especially the decline in estrogen—play a significant role in both joint and bone health.
Estrogen helps regulate bone remodeling, and when levels drop, bone loss accelerates. This not only increases the risk of osteoporosis but may also influence joint health and the progression of osteoarthritis.
Additionally, women tend to experience a natural decline in bone density as they age, making it even more important to monitor bone health proactively.
Understanding Bone Density and Why It Matters
Bone density, or bone mineral density (BMD), refers to the amount of minerals—primarily calcium and phosphorus—present in your bones. It is a key indicator of bone strength and fracture risk.
Healthy bone density is essential for supporting your joints. Strong bones provide a stable framework for movement, help absorb impact, and reduce the likelihood of fractures—especially in areas already affected by osteoarthritis. (genesis-hospital.com)
Low bone density, on the other hand, can lead to conditions like osteopenia and osteoporosis, which significantly increase the risk of fractures. In fact, weakened bones are more likely to break even with minor falls or stress, particularly in the hips and spine. (Wikipedia)
What Is a Bone Density Scan (DEXA Scan)?
A bone density scan—most commonly performed using dual-energy X-ray absorptiometry (DEXA)—is a quick, non-invasive test that measures the strength of your bones.
During the scan, low-dose X-rays are used to evaluate bone density in key areas such as the hips and spine. The procedure is painless, typically takes less than 30 minutes, and provides valuable insight into your fracture risk and overall bone health. (EP Wellness & Functional Medicine Clinic)
Results are reported as T-scores, which compare your bone density to that of a healthy young adult. Lower scores indicate decreased bone density and a higher risk of fractures.
Bone Density Scans and Osteoarthritis: What’s the Connection?
It’s important to understand that a bone density scan does not diagnose osteoarthritis. OA is a joint condition that affects cartilage and is typically evaluated through physical exams and imaging like X-rays. (Verywell Health)
However, bone density scans still play a crucial role in the overall picture of musculoskeletal health—especially for women with or at risk for osteoarthritis.
Here’s why:
- Fracture prevention: Osteoarthritis can affect mobility and balance, increasing the risk of falls. Low bone density further raises the likelihood of fractures.
- Comprehensive care: Many women with OA also have or are at risk for osteoporosis, making bone health monitoring essential.
- Tracking changes over time: Bone density scans can establish a baseline and monitor how your bones respond to aging, hormonal changes, or treatment. (EP Wellness & Functional Medicine Clinic)
In short, while osteoarthritis and bone density are different conditions, they are closely linked when it comes to maintaining strength, stability, and independence.
Who Should Get a Bone Density Scan?
Bone density screening is especially important for women, particularly as they age. General guidelines recommend:
- Women age 65 and older
- Postmenopausal women under 65 with risk factors (such as family history, low body weight, or certain medications)
- Women with a history of fractures or conditions that affect bone health
Early screening allows providers to detect bone loss before it leads to serious complications. In many cases, osteoporosis is not diagnosed until a fracture occurs—making proactive testing critical. (IPPF -)
Protecting Your Bones and Joints
The good news is that there are many ways to support both bone density and joint health:
- Stay active: Weight-bearing exercises like walking and strength training help maintain bone density and joint function
- Prioritize nutrition: Calcium, vitamin D, and protein are essential for strong bones
- Maintain a healthy weight: Reduces stress on joints while supporting overall health
- Avoid smoking and excessive alcohol: Both can negatively impact bone health
- Follow up with your provider: Regular check-ups and screenings ensure early detection and intervention
These lifestyle strategies not only support bone strength but can also help reduce the progression and symptoms of osteoarthritis.
