Purpose Thumb metacarpophalangeal joint radial instability occurs during the pinch motion in patients with hypoplastic thumb because of thumb-index web narrowing. We devised a radiographic technique to measure the thumb-index angle, applied while the patient holds a styrene foam cone, to evaluate th...
