What Is Subtalar Instability?
Often called flat feet or overpronation, subtalar instability occurs when:
- The talus (ankle bone) partially dislocates over the calcaneus (heel bone)
- Motion exceeds normal range (3-5 degrees)
- Foot mechanics become compromised
Impact on Foot Health
This excessive motion can cause multiple problems:
Plantar Fascia Issues
- Strain on the broad ligament under your foot
- Micro tears in the tissue
- Inflammation and thickening
- Often misdiagnosed as simple plantar fasciitis
Great Toe Joint Problems
- Excessive strain on the first metatarsal joint
- Altered sesamoid bone position
- Compromised joint function
- Changes in forefoot mechanics
Traditional Treatment Limitations
Common approaches have shown limited success:
Orthotics and Arch Supports
- May provide some arch support
- Don't address excessive subtalar motion
- Don't correct underlying instability
Traditional Surgery
- Procedures like calcaneal osteotomy
- May not fully correct subtalar position
- Don't always address root cause
Advanced Solution: Extra-Osseous Talotarsal Stabilization
This innovative treatment offers several advantages:
- Minimally invasive approach
- Small stent placement
- Avoids joint interference
- Restores normal motion (3-5 degrees)
- Addresses root cause of instability
Benefits of This Approach
- Significantly limits excessive motion
- Maintains healthy joint function
- Corrects underlying misalignment
- Verifiable results through imaging
- Restores natural foot mechanics
This advanced treatment option provides a solution that addresses the root cause of subtalar instability while maintaining proper foot function. By restoring normal motion rather than restricting it entirely, we can help patients achieve long-term relief from their symptoms.
