Objective: The fractures of the distal part of the humerus con- stitute 0.5–2% of all bony fractures. Approximately 33% of these fractures involve the elbow joint. Anatomical reduction of the fracture is very important for painless, stable and mobile elbow joint restoration. Many surgical methods including olecranon osteotomy and the triceps lifting approach are used to treat. The anatomical features of distal humerus should always be kept in mind for internal fixation which is commonly used as a surgical procedure.

 Methods: The measurements of distal humerus were per- formed in 50 dried adult humerus which were used as educa- tional materials in anatomy laboratories and in 50 radiogra- phies of the humerus which are reported as normal by the radi- ologist.

Results: Mean length of humerus (mean±SD) was measured as 300.8 mm (±17.3). The mean lenght and width of capitulum humeri were 18.26 mm (±2.56), 19.45 mm (±2.01), respective- ly. The mean lenght and width of trochlea humeri were 14.32 mm (±1.97), 21.73 mm (±2.16) respectively.The distance between medial and lateral epicondyle were measured as 58.38 mm (±4.41).The mean lenght, width and depth of coronoid fossa were 9.56 mm (±1.78), 13.07 mm (±2.28), 4.48 mm (±0.81), respectively.The mean lenght, width and depth of ole- cranon fossa were 19.39 mm (±2.37), 26.16 mm (±3.17), 14.35 mm (±2.43), respectively.

Conclusion: Morphometric data of distal humerus obtained from dry bones and radiographs may useful for surgical proce- dures performed in this area.
