Summary
Hydrodissection and corticosteroid injections effectively treat carpal tunnel syndrome, improving symptoms and nerve function. No significant differences were found between these ultrasound-guided and traditional injection methods.
Area of Science:
- Orthopedics
- Neurology
- Medical Imaging
Background:
- Carpal tunnel syndrome (CTS) is a common condition affecting nerve function.
- Hydrodissection is an emerging ultrasound-guided technique for CTS management.
- Comparing hydrodissection with traditional corticosteroid injections is crucial for treatment optimization.
Purpose of the Study:
- To compare the efficacy of hydrodissection (with or without corticosteroids) against intra-carpal corticosteroid injection for CTS.
- To evaluate treatment outcomes including nerve size, symptom severity, and electrodiagnostic measures.
Main Methods:
- 66 wrists with mild to moderate CTS were divided into three groups.
- Ultrasound-guided hydrodissection with corticosteroid/lidocaine/saline or lidocaine/saline.
- Ultrasound-guided and non-guided intra-carpal corticosteroid injections.
- Outcomes assessed at 3 months included median nerve cross-sectional area, symptom severity, function, and electrodiagnostics.
Main Results:
- All interventions significantly reduced symptom severity, improved function, and decreased median nerve cross-sectional area (p < 0.05).
- Significant improvements in sensory and motor nerve conduction studies were observed across all groups.
- No significant differences in outcomes were found between the different treatment groups, except for muscle strength.
Conclusions:
- Hydrodissection and intra-carpal corticosteroid injections are effective for managing carpal tunnel syndrome.
- Ultrasound guidance does not appear to offer a significant advantage over traditional methods in this study.
- All evaluated interventions provide comparable improvements in CTS symptoms and nerve function.
