The 18-G needle technique for first dorsal extensor compartment release showed high rates of incomplete release and tendon damage, particularly with an intertendinous septum. Ultrasound guidance may improve outcomes for this percutaneous release method.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Anatomy
Background:
- The first dorsal extensor compartment is crucial for hand function.
- De Quervain's syndrome often involves this compartment.
- Percutaneous techniques are explored for less invasive treatment.
Purpose of the Study:
- To evaluate the efficiency of the percutaneous 18-G needle technique for releasing the first dorsal extensor compartment.
- To identify factors influencing the success of this technique.
Main Methods:
- An 18-G needle was used for percutaneous release on 48 cadaver wrists.
- Specimens underwent dissection to assess release completeness and identify injuries.
- Tunnel length, tendon number, and presence of a septum were analyzed.
Main Results:
- Complete release was achieved in 52% of cases (25/48).
- Tendon complications occurred in 19 wrists (39.6%).
- An intertendinous septum was significantly associated with incomplete release and tendon damage.
Conclusions:
- The 18-G needle technique has limitations for first dorsal extensor compartment release, especially with septa.
- High rates of incomplete release and tendon damage were observed.
- Further research with ultrasound guidance is recommended to improve percutaneous release efficacy.
