Bone surveillance is risk- and symptom-based and DEXA interpretation in children requires expertise. Ask the endocrine/bone team about vertebral-fracture screening and what result would change treatment.
What this means in real life
Bone monitoring in DMD is not a single universal DEXA schedule. Clinicians combine steroid exposure, fracture history, back pain, growth/puberty, mobility and imaging. Lateral spine imaging is important because vertebral compression fractures can occur without dramatic symptoms and may be treatable. DEXA measures bone density but needs height- and age-aware interpretation.
Ask what result would change management. A low DEXA value without symptoms is not interpreted the same way as a vertebral or long-bone fracture. Repeat testing should use the same useful sites and account for positioning limitations. Spine imaging may be obtained sooner for back pain, height loss or posture change.
The bone/endocrine team should connect surveillance to vitamin D/calcium, puberty and growth care, fracture treatment and rehabilitation. Families should keep copies of reports because images and Z-score adjustments are often hard to compare across systems.
A practical checklist
- ✓
Document steroid start date, fractures, back pain and height trend.
- ✓
Ask whether lateral spine imaging is needed now.
- ✓
Use a center able to interpret pediatric DEXA in short stature and DMD.
- ✓
Keep the numerical report and imaging comparison.
- ✓
Schedule follow-up based on findings and ongoing risk—not a generic interval alone.
Questions to bring with you
Use these at the clinic, school meeting, equipment evaluation, program interview or benefits call. Write down the answers and who owns the next step.
- What is the purpose of this scan?
- Was the result adjusted for height and development?
- Could positioning or contracture distort the measurement?
- Is there evidence of vertebral fracture?
- What finding would lead to treatment?
Important context
Individual needs, eligibility and safety can differ. Confirm the plan with the relevant Duchenne-experienced clinician, therapist, school team or program before acting.
