What is Trochlea fracture?
What is Trochlea fracture?
Isolated trochlea fractures are rare but are frequently encountered in complete articular fractures of the distal humerus involving both the trochlea and capitellum. The trochlea forms the articular surface of the medial column of the elbow and is responsible for allowing ulnohumeral flexion and extension.
Is the Trochlea part of the humerus?

What is a olecranon fracture?
An olecranon fracture is a break in the “pointy bone” of your elbow that sticks out when you bend your arm, which is actually the end of the ulna. This type of fracture is common and usually occurs in isolation (there are no other injuries) but can also be a part of a more complex elbow injury.
What are the trochlea and capitulum?
The trochlea and capitulum are the rounded, smooth, knuckle-like surfaces at the anterior and distal end of the humerus. The elbow flexes and extends around these structures. Two outcroppings of bone flank the trochlea and capitulum.
What does a trochlea do?
In each eye, the superior oblique muscle functions as the trochlea. The trochlear nerve innervates this muscle to lift the eyes so you can look down. The nerve also enables you to move your eyes toward your nose or away from it.

Surgery is usually not necessary if the fracture is a type 1 or a milder type 2, and if there are no complications. A cast or a splint can be used to immobilize the joint and allow the natural healing process to begin.
What is a trochanteric hip fracture?
An intertrochanteric fracture is a specific type of hip fracture. “Intertrochanteric” means “between the trochanters,” which are bony protrusions on the femur (thighbone). They’re the points where the muscles of the thigh and hip attach.
What fracture is called a closed fracture?
If the bone is in many pieces, it is called a comminuted fracture. In a non-displaced fracture, the bone cracks either part or all of the way through, but does move and maintains its proper alignment. A closed fracture is when the bone breaks but there is no puncture or open wound in the skin.
Can You fracture cartilage?
Cartilage fracture. If your fracture is due to a forceful blow, such as from an automobile accident, you also may experience a cartilage fracture. If your injury is severe enough to warrant surgical treatment, the surgeon should address both your bone and cartilage injuries. You can help prevent a nose fracture with these guidelines:
