(A) Anteroposterior radiograph of the elbow, showing a Finnbogason type A fracture (stable).
(B) Internal oblique radiograph of the same patient showing a Finnbogason type C (unstable) traversing the capitellum.

Fig. 6Algorithm of treatment. Closed reduction and internal fixation is suggested as first line treatment option for unstable fracture.
Fig. 7
(A) Anteroposterior radiograph showing a completely displaced fracture with rotation of the fracture fragment. Intra-operative (B) anteroposterior and (C) lateral radiographs from same patient showing reduction by pushing the fragment backward and medially with operator's thumb. Intra-operative (D) anteroposterior and lateral (E) radiographs showing final reduction of the fragment <2 mm of displacement with Kirschner wire. (F) Post-reduction aneteroposterior arthrogram showing fixation with three Kirschner wires, congruent reduction of the articular surface.
