A splinting apparatus treating a flexion deformity of a finger includes a phalangeal bracket and a first anchoring ring fixedly attached thereto and positioned on the finger proximally of the deformity, a nail bracket and a second anchoring ring fixedly attached thereto and positioned on the finger distally of the deformity, and a rigid connecting rod extending between, and fixedly attached to at least one of the phalangeal and nail brackets so as to couple the brackets in a spaced apart positional relationship to each other along the finger relative to the flexion deformity. Each of the first and second anchoring rings is formed from an elongated narrow band integrally connected respectively with one of the phalangael and nail brackets and having first and second band extensions being bendable in opposite directions circumferentially around the finger so as to overlap and secure to one another.
