Summary
Surgical decompression significantly improves outcomes for tarsal tunnel syndrome (TTS), offering substantial pain relief and enhanced function. Early intervention may lead to better results, though further research is needed.
Area of Science:
- Orthopedics
- Neurosurgery
- Podiatry
Background:
- Tarsal tunnel syndrome (TTS) is a condition causing foot pain and numbness.
- Conservative treatments often fail, necessitating surgical intervention.
- Diagnostic tools like EMG, MRI, and ultrasound aid in TTS diagnosis.
Purpose of the Study:
- To assess the effectiveness of surgical decompression for TTS.
- To evaluate functional outcomes post-surgery.
- To determine the clinical utility of diagnostic tests in TTS management.
Main Methods:
- A retrospective study of 15 TTS patients undergoing open decompression.
- Preoperative assessment included clinical exams and diagnostic tests (EMG, MRI, ultrasound).
- Outcomes measured by AOFAS score, VAS pain, MCID, and complications at 12 months.
Main Results:
- Significant improvement in AOFAS scores (36.6 to 78.1) and reduction in VAS pain (7.0 to 3.4).
- 80% achieved minimal clinically important difference (MCID) for AOFAS, 100% for VAS.
- Low complication rate (13.3%) with no reoperations.
Conclusions:
- Surgical decompression is a safe and effective treatment for TTS.
- Significant functional gains and pain reduction were observed post-surgery.
- Further prospective studies are recommended to explore early intervention benefits.
