The bone fragment was displaced laterally by the traction of the flexor muscles; however, dislocation of the humeroulnar joint was not observed (Figure 1).
Intraoperative imaging. The white arrow shows the bone fragment, and the black arrow shows the ulnar nerve.

Since multiple temporary fixations with wires were needed to fix the unstable bone fragment, we were afraid of bursting the fragment with a compression screw (Figure 3).
Follow-up from 1 to 4 years and contralateral anteroposterior radiography. (a) The 1-year follow-up examination. The black arrow shows the absorption of the trochlear groove (fishtail deformity). (b) The 2-year follow-up examination. (c) The 3-year follow-up examination. (d) The 4-year follow-up examination. (e) Contralateral anteroposterior radiography.
