Irreducible Phalangeal Fractures Due to Incarceration into the Extensor Tendon Apparatus - A Report of Two Patients.

Irreducible phalangeal fractures are uncommon, and if neglected can cause fracture non-union or functional deficits of the affected digit. We present two patients with irreducible phalangeal fractures - one in a child with a juxta-epiphyseal middle phalanx fracture incarcerated into the triangular ligament of the extensor apparatus and another in an adult following incarceration of a fractured proximal phalanx into the common intrinsic tendon on the radial side. Both required open reduction to extricate the incarcerated fracture ends, achieving good union and excellent functional outcomes. Level V (Therapeutic).
