Sonography-guided arthroscopy for wrist ganglion

Area of Science:

• Orthopedic Surgery
• Diagnostic Imaging
• Musculoskeletal Disorders

Background:

• Wrist ganglions are common soft tissue tumors.
• Arthroscopic resection is a standard treatment, but visualization can be challenging.
• Improving surgical precision is crucial for patient outcomes.

Purpose of the Study:

• To evaluate the combined use of sonography and arthroscopy for wrist ganglion resection.
• To enhance the safety and reliability of arthroscopic ganglion removal.

Main Methods:

• Sonography-assisted arthroscopic resection was performed on 22 patients with wrist ganglions.
• Evaluated sonographic visualization of ganglions, adjacent structures, and arthroscopic shaver.
• Assessed arthroscopic visualization of ganglions and stalks.
• Measured wrist range of motion, grip strength, and Hand 20 scores.

Main Results:

• Sonography successfully visualized ganglion stalks, adjacent structures, and the shaver in all cases.
• Arthroscopy alone visualized ganglion stalks in only 4 patients.
• Patient-rated Hand 20 scores significantly improved (17 to 6).
• No significant changes in wrist range of motion or grip strength were observed.
• Two cases (9%) experienced ganglion recurrence at 6 and 8 months.

Conclusions:

• Sonography-guided wrist arthroscopy offers superior visualization of ganglions and critical structures.
• This combined approach enhances surgical safety by identifying nerves, vessels, and tendons.
• Improved visualization aids in complete ganglion and stalk resection, potentially reducing recurrence.
