5. Anatomy
• The lower end of humerus is enlarged to form the
trochlea medially and capitulum laterally.
• Medial to trochlea is medial epicondyle and
lateral to capitulum is lateral epicondyle.
• The two epicondyles are continuation of lateral
and medial supracondylar ridges respectively.
• Humeroulnar articulation is responsible for
alingement,stability and strength.
• The other two joint are responsible for position
and motion.

7. Epidemiology
• Most common pattern of distal humerus
fracture in adults.
• Most common in adult females and old males.
8. Mechanism Of Injury
• It usually occurs from
Low energy falls in elderly
High energy impact in younger population
• It results from fall on the point of the elbow so
the olecranon is driven into the distal
humerus, splitting the two humerus condyles
apart.
