title: "Butterfly flap": The retinaculum to the rescue of the extensors.
abstract: Extensor digitorum tendon (EDT) tear in the wrist is frequently associated with inflammation (rheumatoid arthritis, chondrocalcinosis) or distal radio-ulnar osteoarthritis. EDT protection and repair is often hampered by poor tissue trophicity and associated procedures. We describe an extensor retinaculum (ER) plasty, protecting and recentering the EDTs. The procedure consists in raising the ER on either side of Lister's tubercle so as to create a strap protecting and recentering the 4th, 5th and 6th compartment EDTs; the 2nd and 3rd compartment EDTs are left free on the lateral side of Lister's tubercle. This "butterfly plasty" provides solid and effective protection of the EDTs in an often fragile pathologic context. It creates a glide space, stabilizing EDTs and wrist.
