Objective: The fractures of the distal part of the humerus constitute 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 performed in 50 dried adult humerus which were used as educational materials in anatomy laboratories and in 50 radiographies of the humerus which are reported as normal by the radiologist.
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), respectively. 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 olecranon 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 procedures performed in this area.
