Combined Isolated Laugier's Fracture and Distal Radial Fracture: Management and Literature Review on the Mechanism of Injury

Oppenheim (16) described a peculiar case of concomitant fracture of the trochlea and capitellum. He suggested that both these fractures occurred due to shear force transmission from the radial head and coronoid to the capitellum and the trochlea respectively in extended position.

In the case of OCD, the loose body is usually located near the capitellum and radial head; for fractures, near the site of injury; for synovial chondromatosis, loose bodies are frequently anterior.

Elbow arthroscopy

The capitellum contains thick hyaline cartilage anteriorly that articulates with the proximal radius.

While this might be sufficient for fixation of a simple capitellum fracture, the coronal shear fracture requires a more extensile exposure of the anterior humeral articular surface.

(3) The radial head fractures are caused by a valgus force on the elbow as the head is driven into the capitellum. Radial head fractures have been classified into four types according to Mason.

Elbow fracture-dislocations: the role of hinged external fixation

In order to determine the effects of two different headless screw designs on fixation of simulated capitellum fractures six matched pairs of embalmed humeri had simulated capitellum fractures created.

The mnemonic "CRITOE" (Capitellum, Radial head, Internal (medial) epicondyle, Trochlea, Olecranon and External (lateral) epicondyle) can help diagnose certain fractures, particularly those where an ossification center 'appears' out of the expected order.

In addition, proximally, the radius abuts the capitellum leading to elbow pain and decreased range of motion.

The Essex-Lopresti Injury

The chronological order of appearance of the elbow ossification centers follows this rule: capitellum, radial head, medial epicondyle, trochlea, olecranon, and lateral epicondyle.
