BOA Dial Thumb Wrist Brace | Adjustable Steel Splint for Carpal Tunnel & Tenosynovitis Relief

Designed for people suffering from thumb and wrist discomfort, this upgraded thumb spica brace features an innovative BOA dial lace system and built-in steel support plates, providing stable immobilization for the thumb joint, limiting tendon friction in the tendon sheath, and effectively relieving pain from tenosynovitis, trigger finger, carpal tunnel syndrome, De Quervain's syndrome and thumb sprains. Ideal for daily wear, night rest and home rehabilitation recovery.

✨ Core Functional Highlights

1. Precision BOA Dial Tension System
   Adopts premium BOA lace system with high-strength pull wire for progressive, stepless compression adjustment:

• Press down the dial knob and twist clockwise to evenly tighten the brace for firm support
• Pull up the knob to release tension instantly for quick removal
  One-hand operation allows you to adjust tightness freely at any time, delivering a more customized and secure fit than ordinary Velcro straps.

2. Dual Aluminum Alloy Steel Plate Support
   Built-in curved rigid support plates on both sides of the thumb fully conform to the natural thumb curve, providing bidirectional strong fixation to stabilize the thumb metacarpal joint, restrict abnormal thumb movement, and prevent secondary injury during daily activities. The thin and lightweight plates add no extra burden to your hand.
3. Breathable 3D Mesh Fabric, All-Day Comfort
   Made of sandwich mesh fabric with large breathable holes, which allows air circulation freely to avoid stuffiness and sweat buildup. Soft skin-friendly lining reduces friction irritation, suitable for long-time wear during work, sleep or summer daily use without discomfort.
4. Universal Fit for Left & Right Hand
   Unisex one-size-fits-most design works for both left and right hands. The adjustable thumb strap with rotary buckle further strengthens fixation, prevents slipping off, and fits different wrist circumferences perfectly.
5. Ergonomic Immobilization Design
   Scientific thumb fixation limits excessive friction between tendons and tendon sheaths, helps reduce swelling and inflammation, and supports natural self-recovery of the tendon sheath with consistent wear. It retains flexible movement of other four fingers, so you can still complete daily tasks easily.
