The triceps-dividing approach to open reduction of complex distal humeral fractures in adolescents: a Cybex evaluation of triceps function and motion.

Triceps function and elbow motion were evaluated in nine elbows after open reduction of complex distal humeral fractures through a triceps dividing approach. At 3-year 6-month follow-up, the patients had an average flexion/extension of 136 degrees to -6 degrees. Triceps peak torque decreased slightly, measured by Cybex testing with a 6% deficit at 60 degrees/s, 3% deficit at 120 degrees/s, and 3% deficit at 180 degrees/s. We recommend triceps division rather than olecranon osteotomy in children who require open reduction of complex distal humeral fractures.
