WHFO
Also written as: WHFO — Wrist-Hand-Finger Orthosis
Acronym for Wrist-Hand-Finger Orthosis, a device that extends support from the wrist through the hand to one or more fingers.
Full Definition
A Wrist-Hand-Finger Orthosis (WHFO) is an orthotic device that encompasses the wrist, hand, and fingers, designed to immobilise, support, or facilitate functional positioning of the entire distal upper extremity. It is commonly prescribed following stroke, spinal cord injury, or tendon repair surgery where finger positioning is critical to outcomes. Editorial confusion between WHFO and WHO (Wrist-Hand Orthosis) is common; the key distinction is whether finger components are included. In billing and clinical documentation, specifying the correct acronym is essential because HCPCS codes differ between WHO and WHFO devices. Editors should check whether any finger components are described in the clinical note to verify the appropriate acronym.
Usage
Usage note: Do not abbreviate to WHO; always use the full four-letter acronym to avoid confusion with Wrist-Hand Orthosis.
