Diagnostic Evaluation and Management of Charcot-Marie-Tooth Disease
Diagnostic Approaches
- MRI is the recommended advanced imaging modality for CMT as it allows comprehensive assessment of bones, joints, ligaments, and tendons 1
- Early diagnosis is critical to prevent deformity and optimize functional outcomes 2, 1
- In cases where CMT is suspected but imaging is inconclusive, further investigations such as dual energy CT or bone biopsy may be warranted 3, 4
Orthotic and Rehabilitation Management
- Total contact casting (TCC) or non-removable knee-high devices are recommended for immobilization and offloading in cases with active neuro-osteoarthropathy 2, 5
- Custom footwear with specialized insoles should be prescribed to ensure ongoing offloading and prevent skin breakdown 6, 7
- Orthotic interventions should be implemented early to prevent progression of deformities 5
Considerations for Management
- Delayed diagnosis and referral to multidisciplinary care can lead to significant clinical deterioration and should be avoided 6, 3
- The presence of ulceration or infection does not exclude underlying CMT-related neuro-osteoarthropathy and should not delay appropriate management 3, 4
- Long-term immobilization with non-removable devices carries risks including muscle weakness, atrophy, falls, and psychological impacts that must be monitored 5
