Heterotopic Ossification of annular ligament: A case report and review of literature.

Abstract

Heterotopic Osification (HO) commonly occurs in the hip and elbow joint post, trauma, surgery or dislocation. HO can occur anywhere in the body, and the term Heterotopic Ossification of Ligaments and Tendon (HOTL) is specifically used to denote HO occurring in ligaments and tendons. HOTL of an annular ligament is reported rarely in the literature. Here we describe a case of calcified annular ligament in a neglected monteggia fracture (Bado Type - 1), which was managed by excision and reconstruction of the same using triceps fascia. Post-op review after 2.5 years showed a stable elbow, with some restriction in pronation.
