A newly published multicenter clinical trial in the peer-reviewed medical journal Plastic and Reconstructive Surgery – Global Open demonstrates that office-based ultrasound-guided carpal tunnel release provides safe, long-term symptom relief and functional recovery over two years of follow-up.
Victor M. Marwin, M.D., a hand and upper extremity surgeon at Vero Orthopaedics, co-authored this landmark research evaluating 149 patients across seven clinical sites nationwide, alongside contributing surgeons including the late Paul D. Paterson, M.D., of Vero Orthopaedics. The results confirm that patients return to routine activities in a median of two days without the need for hospital operating rooms or general anesthesia.
What Did the ROBUST Clinical Trial Discover?
The ROBUST study shows office-based ultrasound-guided carpal tunnel release offers long-lasting pain relief and high satisfaction, making it a compelling option worth discussing during your consultation at Vero Orthopaedics.
Carpal tunnel release is one of the most common hand surgeries performed globally. Historically, these procedures required an operating room at a hospital or an ambulatory surgery center. The ROBUST trial followed 149 patients treated directly in an office procedure room under wide-awake local anesthesia no-tourniquet (WALANT).
Over the 24-month observation window, 92.6% of participants completed their scheduled clinical evaluations. Patient-reported symptom severity dropped dramatically within the first two weeks and remained low through year two. Pain severity scores dropped by a mean of 3.8 points on a 10-point scale. Only one minor complication occurred across 226 treated hands (a 0.4% complication rate per hand), and zero patients required a revision surgery for persistent or recurring nerve compression.
| Clinical Measure | Baseline (Pre-Procedure) | Two-Year Follow-Up | Long-Term Benefit |
|---|---|---|---|
| Boston Carpal Tunnel Questionnaire (BCTQ) Symptom Severity | 3.0 points | 1.25 points | Near-complete symptom relief |
| Boston Carpal Tunnel Questionnaire (BCTQ) Functional Status | 2.27 points | 1.19 points | Full restoration of hand function |
| Numeric Pain Scale (0 to 10 Scale) | 4.3 points | 0.5 points | Sustained reduction in wrist and hand pain |
| Michigan Hand Questionnaire (MHQ) Global Score | 54 points | 88 points | Marked improvement in day-to-day utility |
| Overall Patient Satisfaction | N/A | 95.7% | High, enduring procedural satisfaction |
The peer-reviewed findings were published online on August 26, 2026.
What Is Ultrasound-Guided Carpal Tunnel Release?
Ultrasound-guided carpal tunnel release is a micro-invasive surgical technique that divides the transverse carpal ligament using high-resolution ultrasound imaging rather than an open wrist incision.
In traditional carpal tunnel surgery, a surgeon makes an open incision across the palm and wrist to visualize the internal anatomy directly. By contrast, the minimally invasive approach uses real-time diagnostic ultrasound to see beneath the skin without a large opening.
The procedure utilizes specialized equipment designed for precise visualization. The surgeon administers local numbing medicine and creates an entry point smaller than one centimeter proximal to the wrist crease. A specialized single-use device, known as the UltraGuideCTR, enters the carpal tunnel under continuous ultrasound monitoring. Inflatable protective guards shield the median nerve and neighboring blood vessels while a small retrograde blade cleanly cuts the transverse carpal ligament. This instantly releases pressure inside the carpal tunnel. In 99% of procedures evaluated in the ROBUST study, the small puncture was closed simply using sterile adhesive strips, eliminating the need for traditional sutures.
According to clinical treatment guidelines from the American Academy of Orthopedic Surgeons (AAOS), relieving pressure on the median nerve is critical to prevent irreversible nerve injury and muscle wasting in chronic cases.
How Long Is Recovery After Office-Based Carpal Tunnel Release?
Recovery after office-based ultrasound-guided carpal tunnel release typically takes 2 to 4 days for most individuals to resume light daily activities and work, helping you feel reassured about a swift return to normal life.
Because the procedure does not cut through sensitive palmar skin or underlying muscle, post-procedure recovery is remarkably faster than standard operative methods. In conventional open carpal tunnel procedures, patients frequently miss between 18 and 31 days of work while waiting for palmar tissue incisions to heal.
In the ROBUST trial co-authored by Dr. Marwin and Dr. Paterson:
- Patients resumed normal daily living activities within a median of two days.
- Patients returned to work in a median of four days.
- Desk-based workers returned to work in a median of three days.
- Light manual laborers returned in a median of four days.
- Heavy manual laborers returned to work in a median of four days.
- Only 10.1% of patients required post-procedure prescription pain medication, with a median use of just three days.
- At one year, 94.6% of hands were entirely free of incision sensitivity or scar discomfort.
Can Both Hands Undergo Carpal Tunnel Release at the Same Time?
Yes, eligible patients with nerve compression in both wrists can safely undergo simultaneous bilateral carpal tunnel release in a single office visit.
When both hands suffer from carpal tunnel syndrome, conventional surgery normally forces patients to stage their operations several months apart. This doubles total recovery time, extends time away from work, and increases the number of medical appointments.
The ROBUST trial evaluated 72 patients receiving unilateral release (one hand) and 77 patients receiving simultaneous bilateral release (both hands treated in the same session). Key findings from this comparison include:
- Both groups achieved the same median recovery speed, returning to routine daily activities in just two days.
- Unilateral patients returned to work in three days, and bilateral patients in four days.
- Opioid medication requirements were nearly identical (11.1% in the unilateral group versus 9.1% in the bilateral group).
- Long-term symptom relief, hand functional recovery, and quality-of-life scores at two years showed no statistically significant differences between groups.
Treating both hands in a single appointment lets patients recover once, minimizing time away from family and work.
Why Does the Office Setting Matter for Hand Procedures?
Choosing office-based hand procedures at Vero Orthopaedics offers convenience, cost savings, and faster recovery, making treatment easier and more accessible for patients.
Standard hospital operating rooms involve prolonged fasting, facility fees, IV lines, and preoperative clearances. Office-based release relies on wide-awake local anesthesia no-tourniquet (WALANT). This eliminates the grogginess, nausea, and cardiovascular stress often associated with sedation or general anesthesia.
Performing the procedure in an office exam room also removes costly hospital and surgical center facility charges, while freeing up regional hospital operating rooms for complex, emergency surgeries. Patients arrive in comfortable street clothes, receive treatment in a familiar setting, communicate with their care team throughout, and walk out shortly after the procedure.

Frequently Asked Questions (FAQ)
What are the main symptoms of carpal tunnel syndrome?
The primary symptoms of carpal tunnel syndrome include numbness, tingling, burning, or aching pain in the thumb, index finger, middle finger, and half of the ring finger. Symptoms frequently worsen at night or during repetitive hand tasks, such as driving, typing, or holding a phone. Over time, weakness in hand grip and frequent dropping of objects may occur.
Does ultrasound-guided carpal tunnel release leave a scar?
Ultrasound-guided carpal tunnel release leaves a minimal scar, typically less than one centimeter wide, positioned proximal to the wrist flexion crease. Because the technique avoids incisions across the palm, the cosmetic result is subtle, and 99.5% of study participants reported complete satisfaction with their incision appearance at one year.
Is the carpal tunnel release procedure painful?
The procedure is virtually painless because the surgeon numbs the wrist and hand thoroughly using local anesthetic before beginning. Patients remain fully awake and can speak with their care team throughout the appointment. Mild soreness following the procedure is typical and is easily managed with over-the-counter pain relievers or ice.
How quickly can I use my hand after an in-office carpal tunnel release?
Most patients are encouraged to use their hands for light activities, such as eating, writing, and dressing, immediately or within 24 to 48 hours. Heavy gripping, repetitive forceful twisting, and heavy manual labor are gradually reintroduced over the subsequent week depending on clinical healing.
